What is the slope of the line through (-1, 4) and (1, -2)?
Answer:
slope = - 3
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 4) and (x₂, y₂ ) = (1, - 2)
m = [tex]\frac{-2-4}{1+1}[/tex] = [tex]\frac{-6}{2}[/tex] = - 3

x² + 4x = 0
Answer:
(x+2)^2 = 4
Step-by-step explanation:
x² + 4x = 0
Take the coefficient of the x term
4
Divide by 2
4/2 =2
Square it
2^2 =4
Add this to each side
x^2+4x+4 = 0+4
(x+4/2)^2 = 4
(x+2)^2 = 4
Of the 24,400 working hours logged at a beauty salon last year, Beatrice worked 976 hours. What percentage of the total hours did Beatrice work?
Answer: 4% (or 4.1% when rounded to the nearest tenth or 4.08 % when rounded to the nearest hundredth)
Step-by-step explanation:
First, you would need to put it into a fraction.
You have [tex]\frac{996}{24400}[/tex].
When you divided it, you would get:
0.04081....
Then you have to multiply times 100 to get it into percent form. This gives you:
4.081%
Then, round as you please!

B 24 cups
C 32 cups
D 48 cups
Answer:
The answer is C

There are 32 oz in a quart, 8 oz in a cup, and therefore 4 cups
in a quart. 4 cups(quart) X 8 quarts (Punch bowl)= 32 cups
The figure below has one base
and eight lateral faces. Find its surface
area to the nearest whole number.
Answer: B
Total surface area = 320 m^2
Step-by-step explanation:
The figure is a combination of a cuboid and pyramid.
The Surface Area of a Pyramid When all side faces are the same:
[Base Area] + 1/2 × Perimeter × [Slant Length]
Let us use pythagorean theorem to calculate the slant length
Slant length = root(6^2 + 4^2)
Slant length = 7.2 m
Base area = 8 × 8 = 64 m^2
Perimeter = 8+8+8+8 = 32 m
Surface area of the pyramid will be
= 64 + ( 1/2 × 32 ) × 7.2
= 64 + 16 × 7.2
= 64 + 115.4
= 179.4 m^2
The surface area of the cuboid will be
LB + LH + BH = 8×8 + 8×5 + 8×5
= 64 + 40 + 40
= 144 m^2
Total surface area = 179.4 + 144
Total surface area = 323.4 m^2
= 320 m^2 to the nearest whole number.
Consider the equation, 3x+4y=12.
Write the equation in slope-intercept form.
Identify the y-intercept.
Identify the slope.
The equation in slope-intercept form is y = -3x/4 + 3.
The y-intercept is 3.
The slope is -3/4.
What is the slope-intercept form?In Mathematics and Geometry, the slope-intercept form of the equation of a straight line is given by this mathematical equation;
y = mx + b
Where:
m is the slope or rate of change.x and y are the points.b is the y-intercept or initial value.Based on the information provided about this line, a linear equation that models it is given by;
y = mx + b
3x + 4y = 12
By making y the subject of formula, we have the following:
4y = -3x + 12
4y/4 = -3x/4 + 12/4
y = -3x/4 + 3
Therefore, the y-intercept is 3 and the slope is -3/4.

4. If a student is chosen at random from

what is the probability that the student
participates in school sports, given that
the student is a male?
Answer choices:
0.379
0.476
0.524
0.621
Answer:
0.524
Step-by-step explanation:
To find the probability that a student participates in school sports given that the student is a male, we use conditional probability. The probability is approximately 0.624.
Explanation:To find the probability that a student participates in school sports given that the student is a male, we need to use conditional probability. Conditional probability is calculated by dividing the probability of two events happening together by the probability of the given condition.
Let's denote the event of a student participating in school sports as A and the event of a student being a male as B.
The probability of a student participating in school sports and being a male is given as 0.409. The probability of a student being a male is given as 0.654. Therefore, the conditional probability of a student participating in school sports given that the student is a male can be calculated as:
P(A|B) = P(A and B) / P(B)
P(A|B) = 0.409 / 0.654 ≈ 0.624
So, the probability that a student participating in the survey participates in school sports, given that the student is a male, is approximately 0.624.

The sum of three numbers is -39.22. One of the numbers is 22.8. The other two numbers are equal to each other. What is the value of the other two numbers?
Answer:
The value of the other two numbers is 31.01
Step-by-step explanation:
Let the two numbers equal to each other be x
One of the numbers is 22.8
The sum of three numbers is -39.22.
So, x+x+22.8=-39.22
2x+22.8=-39.22
2x=-39.22-22.8
2x=-62.02
[tex]x=\frac{-62.02}{2}[/tex]
x=-31.01
Hence the value of the other two numbers is 31.01

Help me please again :))
Answer:
x= 15
Step-by-step explanation:
85 and 6x+5 form a straight line.
They sum to 180
85+ 6x+5 = 180
Combine like terms
90 +6x = 180
Subtract 90 from each side
90+6x-90 = 180-90
6x = 90
Divide each side by 6
6x/6 = 90/6
x =15
Answer: x = 15
Step-by-step explanation: since it's a straight line so it's 180 degrees
so 6x + 5 = 95
6x = 90
x = 15

which box plot represents a data set with a lower quartile or 24 and an upper quartile of 42
The box plot that represents a data set with a lower quartile of 24 and an upper quartile of 42 from the given option is D(The bottom option on the right end).
What are quartiles?When we get data that can be compared relatively with each other, for finding quartiles, we arrange them in ascending or descending order.
Quartiles are then selected as 3 points such that they create four groups in the data, each group approximately possessing 25% of the data.
The lower quartile, also called the first quartile has approx 25% in its left partition, and on its right lies approx 75% of the data.Similarly, the second quartile (also called median) is approximately in mid of the data.The third quartile (also called the upper quartile) has approx 75% in its left partition, and on its right lies approx 25% of the data.Left to right is said in the assumption that data were arranged increasingly from left to right
Since we need to find the box plot that has a lower quartile of 24 and an upper quartile of 42, therefore, we need to find a box plot whose rectangle starts at 24 and ends at 42, from left to right.
Hence, the box plot that represents a data set with a lower quartile of 24 and an upper quartile of 42 from the given option is D(The bottom option on the right end).
