Answer:
The desired equation is y = x + 8.
Step-by-step explanation:
As we move right from (-2,6) to (4,12), x increases by 6 and y also increases by 6. Thus, the slope, m, m = rise / run, is m = 6/6, or just m = 1.
Start with the slope intercept form y = mx + b. Since m = 1, we now have y = x + b. Subbing 4 for x, 12 for y, we can find b: 12 = 4 + b. Thus, b = 8.
The desired equation is y = x + 8.
Answer:
The answer to your question is y=1x+8
Step-by-step explanation: We already know that the slope formula is:
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
Substitute the values to find the slope
m= 12-6/4-(-2)
m= 6/4+2
m= 6/6
m=1, so, therefore, the slope is 1
And the y-intercept would be 8

Sandy mixed together 9 gallons of one brand of juice and 8 gallons of a second brand of juice which contains 48% real fruit juice. Find the percent of real fruit juice in the first brand if the mixture contained 30% real fruit juice.
A) 18%
B) 140%
C) 180%
D) 14%
Answer:
D) 14%
Step-by-step explanation:
Let the percent of the real fruit in the first brand = x
Given that number of gallons of real fruit in the first brand = 9 gallons
Given that percent of the real fruit in the second brand = 48%
Given that number of gallons of real fruit in the second brand = 8 gallons
Given that percent of the real fruit in the mixture = 30%
then number of gallons of real fruit in the mixture = (9+8) = 17 gallons
Then we get equation:
[x% of 9 gallons] + [48% of 8 gallons] = [30% of 17 gallons]
9x+48(8)=30(17)
9x+384=510
9x=510-384
9x=126
x=126/9
x=14
Hence final answer is D) 14%

Andrew is paid $4 per hour for the first 30 hours he works each week. He makes $5 per hour for each hour he works over 30 hours per week. In other words, total wages = fixed wages for 30 hours + additional wages at $5 per hour. Apply function notation to answer the following questions about Andrew’s wages. Part A Write a function that gives Andrew’s total wages when he works more than 30 hours. Use the variables w for wages and h for hours.
Answer:
w = 120 + 5*(h-30)
Step-by-step explanation:
Part A;
We are informed that Andrew is paid $4 per hour for the first 30 hours he works each week and makes $5 per hour for each hour he works over 30 hours per week. This implies that the $4 per hour for the first 30 hours is fixed while the $5 per hour overtime depends on the number of extra hours worked.
If we let w denote the wage and h denote the hours worked per week, then;
$4 per hour for the first 30 hours; 4*30 = 120
The number of extra hours worked would be; h-30
w = 120 + 5*(h-30)
This is the function that gives Andrew’s total wages when he works more than 30 hours each week.

doroteo determined that the correlation coefficient for a set data was -0.9. what percent of the total variation in the y-values is not explained by the regression line?
Answer:
19% of the total variation in the y-values is not explained by the regression line
Step-by-step explanation:
The correlation coefficient, r, is a measure of the degree of association between two variables. It gives information on the direction and strength of the relationship.
On the other hand, [tex]R^{2}[/tex] is the coefficient of determination and is a measure of the percent of the total variation in the y-values explained by the regression line.
[tex]R^{2}[/tex] is simply the square of r;
[tex]R^{2}=r^{2}=(-0.9)^{2}=0.81[/tex]
This implies that 81% of the total variation in the y-values is explained by the regression line. Therefore, only 19% is not explained.
The odometer of a new automobile functions improperly and registers only 2 miles for every 3 miles driven. If the odometer indicates 48 miles, how many miles has the automobile actually been driven?
Final answer:
The odometer reads 2 miles for every 3 actual miles driven. To find the actual distance when the odometer shows 48 miles, a proportion is used, leading to the calculation that the automobile has driven 72 actual miles.
Explanation:
The student is dealing with a proportion problem in mathematics where the automobile's odometer is inaccurate. Given that the odometer registers 2 miles for every 3 miles driven, we can set up a proportion to find the actual distance driven. If the odometer indicates 48 miles, we can write the proportion as follows:
2 miles (odometer) / 3 miles (actual) = 48 miles (odometer) / x miles (actual)
Cross-multiply to solve for x: 2x = 48 × 3
Calculate x: 2x = 144
Divide both sides by 2 to isolate x: x = 144 / 2
Find the value of x: x = 72 miles
Therefore, the automobile has actually been driven 72 miles.
A product costs $29.75 for 5 pounds. How much does it cost per ounce? (1 pound = 16 ounces)
Answer:
The product costs $0.37 per ounce.
Step-by-step explanation:
$29.75 for 5 pounds = x for 1 pound (Cross-Multiply)
5x/5 = $29.75/5
x = $5.95 per pound
$5.95 per pound/16 ounces = $0.37
$0.37 per ounce!
Answer:
$0.371875 does it cost per ounce.
Step-by-step explanation:
Use conversion:
1 pound = 16 ounces.
As per the statement:
A product costs $29.75 for 5 pounds.
In 5 pounds = product cost $ 29.75
then;
In 1 pound = [tex]\$\frac{29.75}{5}[/tex]
Using conversion we have;
In 16 ounces = [tex]\$\frac{29.75}{5}[/tex]
then;
in 1 ounces = [tex]\$\frac{29.75}{80} = \$0.371875[/tex]
Therefore, $0.371875 does it cost per ounce.
Find an equation for the nth term of the arithmetic sequence.
a10 = 32, a12 = 106 (2 points)
an = -301 + 37(n - 1)
an = -301 + 37(n - 2)
an = -301 + 37(n + 1)
an = -301 - 37(n + 1)
I hope this helps witb you.
Final answer:
To find the nth term of the arithmetic sequence, we calculated the common difference to be 37, and deduced the first term as -301. The equation for the nth term is an = -301 + 37(n - 1). Therefore, option a is correct answer.
Explanation:
To find an equation for the nth term of the arithmetic sequence given two terms, a10 = 32 and a12 = 106, we first need to determine the common difference. The common difference d in an arithmetic sequence is the consistent interval between consecutive terms, calculated by subtracting one term from the next. In this case:
d = a12 - a10
d = 106 - 32
d = 74
Since the terms are two positions apart, this common difference corresponds to two steps, meaning the common difference per step is 74 / 2 = 37.
Now, we know that the general formula for the nth term of an arithmetic sequence is:
an = a1 + (n - 1)d
Where a1 is the first term. To find a1, we can plug in the values for a10:
32 = a1 + (10 - 1)×37
32 = a1 + 9×37
32 = a1 + 333
a1 = 32 - 333
a1 = -301
Now, the equation for the nth term of the sequence is:
an = -301 + 37(n - 1)
Therefore, option a is correct answer.

An Easter basket contains eggs of three different colors. Find the total number of eggs in the basket if 2 7 of all eggs are green, 1 4 of all are blue and the rest 26 eggs are red.
Answer:
Total number of eggs in basket = 56
Step-by-step explanation:
Let z be the total number of eggs
Green eggs = [tex]\frac{2}{7}[/tex] × z ........1
Blue eggs = [tex]\frac{1}{4}[/tex] × z .......2
Rest of eggs = 26 ........3
The addition of 1, 2 and 3 is equal to z
[tex]\frac{2}{7}[/tex] × z + [tex]\frac{1}{4}[/tex] + 26 = z
[tex]\frac{8z + 7 z}{28}[/tex] + 26 = z ∵GCF for 4 and 7 is 28
[tex]\frac{15z}{28}[/tex] + 26 = z
15z + (26 × 28) = 28z ∵ multiply both sides by 28
15z + 728 = 28z
28z - 15z = 728 .......... rearranging above equation
13z = 728 ⇒ z = [tex]\frac{728}{13}[/tex] ⇒ z = 56
Total number of eggs = z = 56
Answer: There are total 56 eggs in the basket.
Step-by-step explanation: Given that an Easter basket contains eggs of three different colors, out of which [tex]\dfrac{2}{7}[/tex] are green, [tex]\dfrac{1}{4}[/tex] are blue and rest 26 eggs are red.
We are to find the total number of eggs in the basket.
Let x be the total number of eggs in the Easter basket.
Then, according to the given information, we have
[tex]\dfrac{2}{7}\times x+\dfrac{1}{4}\times x+26=x\\\\\\\Rightarrow \dfrac{8x+7x}{28}+26=x\\\\\\\Rightarrow \dfrac{15x}{28}+26=x\\\\\\\Rightarrow x-\dfrac{15x}{28}=26\\\\\\\Rightarrow \dfrac{28x-15x}{28}=26\\\\\\\Rightarrow \dfrac{13x}{28}=26\\\\\Rightarrow x=\dfrac{26\times 28}{13}\\\\\Rightarrow x=56.[/tex]
Thus, there are total 56 eggs in the basket.
7 example of independent event
8 pieces of fruit are drawn twice with replacement what is P
Answer:
7.
rolling two number cubes
8.
2/25
Step-by-step explanation:
7.
Events A and B are said to be statistically independent if the probability of A happening, P(A), in no way affects the probability of event B occurring, P(B);
P(A∩B) = P(A) P(B)
If A and B are independent the above equation is always true.
From the list given, rolling two number cubes is an example of independent events since the outcome from the first cube does not affect the outcome of the second cube.
8.
We are informed the bag contains 4 apples, 1 plum, 2 apricots, and 3 oranges. We are required to determine the following probability;
P(Apple then Apricot) given that the fruits are drawn with replacement.
The probability of drawing an apple from the bag is;
(number of apples)/(total number of fruits)
= 4/10 = 2/5
The probability of drawing an apricot from the bag given that the apple drawn is replaced is;
(number of apricots)/(total number of fruits)
= 2/10 = 1/5
Now, P(Apple then Apricot) = 2/5 * 1/5 = 2/25

An irregular polygon has its external angles as 28°,40°,120°,142° and x. Find the value of x
Answer:
X=30
Step-by-step explanation:
The whole polygon is 360 degrees so:
360-28-40-120-142=X, which is 30
The value of x = 30°.
What is an exterior angles of an Irregular Polygon?
As in the case with a regular polygon, an irregular polygon even contains exterior angles that count up to 360°. Each exterior angle in an irregular polygon even exists (180° - its linear pair). Therefore the exterior angles add up to 360°.
The entire external angle is equal to 360.
28° + 40° + 120° + 142° + x = 360°
Simplifying the above equation, we get
330° + x = 360°
x = 360°- 330°
x = 30°
Therefore, the value of x = 30°.

find the volume of the sphere. express your answer in term of Pie
Answer:
[tex]\large\boxed{36\pi}[/tex]
Step-by-step explanation:
The formula of a volume of a sphere:
[tex]V=\dfrac{4}{3}\pi R^3[/tex]
R - radius
We have R = 3 ?. Substitute
[tex]V=\dfrac{4}{3}\pi(3^3)=\dfrac{4}{3}\pi(27)=(4)\pi(9)=36\pi[/tex]
If the radius is 30, then the volume is:
[tex]V=\dfrac{4}{3}\pi(30^3)=\dfrac{4}{3}\pi(27,000)=(4)\pi(9,000)=36,000\pi[/tex]
If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:
[tex]V=\dfrac{4}{3}\pi(15^3)=\dfrac{4}{3}\pi(3,375)=(4)\pi(1,125)=4,500\pi[/tex]
For what values of a and m does f(x) have a horizontal asymptote at y = 2 and a vertical asymptote at x = 1?
for a rational expression the vertical asymptotes occur when the denominator equals 0, in this case that will be when x + a = 0.
now, if there were to be a vertical asymptote of x = 1, that simply means that
x = 1 ==> x - 1 = 0.
meaning that a = -1.
horizontal asymptotes occur when the denominator has a higher degree than the numerator OR when both have the same degree.
when the degree of the denominator is higher, then the only horizontal asymptote occurring is y = 0.
when the degrees are the same, then the horizontal asymptote occurs at the leading terms' coefficient fraction.
now, if this expression were to have a horizontal asymptote of y = 2, that simply means
[tex]\bf \cfrac{2x^m}{x+a}\implies \cfrac{2x^1}{1x^1+a}\implies \stackrel{\textit{horizontal asymptote}}{\cfrac{2}{1}\implies y=2}\qquad \textit{meaning m = 1}[/tex]
ANSWER
a=-1,m=1
EXPLANATION
The given function is
[tex]f(x) = \frac{2 {x}^{m} }{x + a} [/tex]
For this rational function to have a horizontal asymptote at y=2, the degree of the numerator must equal the degree of the denominator.
This implies that, we must have m=1.
For the function to have a vertical asymptote at x=1, then,
[tex]1 + a = 0[/tex]
This implies that,
[tex]a = 0 - 1[/tex]
[tex]a = - 1[/tex]

andre drinks 15 ounces of water, which is 3/5 of a bottle. How much does the bottle hold? Use x for the number of ounces of water the bottle holds.
Answer:
25 ounces of water
Step-by-step explanation:
3/5 = 15
Cross multiplying this:
1 = x
3/5 = 15
3/5x=15
x=25
Answer:
The bottle hold 25 ounces of water
Step-by-step explanation:
To find the amount of water the bottle hold, we will follow the steps below;
let x be the number of ounces of water the bottle holds
3/5 of x = 15 ounces
3/5 × x = 15
[tex]\frac{3X}{5}[/tex] = 15
Multiply both-side of the equation by 5
[tex]\frac{3X}{5}[/tex] × 5 = 15×5
At the left-hand side of the equation 5 will cancel-out 5 leaving us with 3x
3x = 75
Divide both-side of the equation by 3
[tex]\frac{3X}{3}[/tex] = [tex]\frac{75}{3}[/tex]
(On the left-hand side of the equation 3 at the numerator will cancel-out 3 at the denominator leaving us with x while on the right-hand side of the equation 75 will be divided by 3)
x = 25 ounce
ASAP HELP PLEASE A cylinder and its dimensions are shown. Which equation can be used to find V, the volume of the cylinder in cubic centimeters?
A)
V = π(4.5h)2
B)
V = π(9h)2
C)
V = π(4.5)2h
D)
V = π(9)2h
Answer:
Option A, π(4.5)²
Step-by-step explanation:
Volume of a cylinder is-
V = πr²h
Substitute the value of the radius. (9 is the diameter of the base, so it needs to be half of it)
V = π(4.5)²h
Bring the "h" inside with 4.5
V = π(4.5h)²
Hope this helps
The volume of the cylinder is [tex]\pi (4.5)^{2} h[/tex] and thus option c) [tex]\pi (4.5)^{2} h[/tex] is the correct option
Given: a cylinder of diameter 9 cm and height h cm
To find: equation to find the volume of the cylinder
We know that the volume of a cylinder can be calculate by using the formula:
[tex]\text{volume} = \pi r^{2} h[/tex]
where r is the radius of the cylinder and h is the height
It is given that the diameter of cylinder is 9 cm so radius of the cylinder will be half of the diameter:
[tex]\text{radius} = \frac{9}{2} = 4.5[/tex] cm
Now putting the values in the formula of volume:
[tex]\text{volume} = \pi (4.5)^{2} h[/tex]
Therefore, the volume of the cylinder is [tex]\pi (4.5)^{2} h[/tex] and the option that is same as our answer is option C. So, option C) [tex]\pi (4.5)^{2} h[/tex] is the correct answer
