Six times a number plus another number tripled

Answer:

[tex]\displaystyle y > \frac{1}{4} x+1[/tex]

Step-by-step explanation:

To find the inequality of the shaded area which passes through points (-4, 0) and (4, 2), first we need to find the equation of the line.

To find the equation that passes through (x₁, y₁) and (x₂, y₂), we use this formula:

[tex]\boxed{\frac{y-y_1}{y_2-y_1}=\frac{x-x_1}{x_2-x_1} }[/tex]

Given:

Then:

[tex]\begin{aligned}\frac{y-y_1}{y_2-y_1}&=\frac{x-x_1}{x_2-x_1}\\\\\frac{y-0}{2-0}&=\frac{x-(-4)}{4-(-4)}\\\\\frac{y}{2}&=\frac{x+4}{8}\\\\y&=\frac{1}{4}x+1 \end{aligned}[/tex]

Now, we look at the line in the graph. Since the line is a dotted line, which means that the line is excluded from the shaded area. Then we can only use < or > for the inequality (instead of ≤ or ≥).

Finally, we look at the shaded area. Since the area is above the line, which means the y-value of the area is larger than the y-value of the equation (line), then we will use the larger than sign (>) and the answer will be:

[tex]\displaystyle y > \frac{1}{4} x+1[/tex]

Answer:

D. 12.3 ft

Step-by-step explanation:

This problem requires the use of trigonometric ratios. This one specifically uses the cosine ratio as it provides the hypotenuse and is asking for the side that is adjacent to the angle.

cos(40°)=a/16

cos(40°)×16=a/16×16

cos(40°)×16=a

a=12.256 ft

The length of side a is D. 12.3 ft.

Answer:

a) Length [tex]x + 12[/tex], Width [tex]x - 3[/tex], b) [tex]x = 3[/tex]

Step-by-step explanation:

a) The expressions for the length and width of the parallelogram can be determined by factorizing the polynomial:

[tex]A = x^{2} + 9\cdot x - 36[/tex]

[tex]A = (x+12)\cdot (x-3)[/tex]

Length

[tex]x + 12[/tex]

Width

[tex]x - 3[/tex]

b) Since area is a positive variable, the set of solutions encompass all values of x such that area is zero o greater. Then, there are two interval where A is positive:

- When both binomials are negative.

[tex]x \leq 3[/tex] and [tex]x \leq -12[/tex]

[tex]x \leq -12[/tex]

- When both binomials are positive.

[tex]x \geq 3[/tex] and [tex]x \geq -12[/tex]

[tex]x \geq 3[/tex]

Since x is an integer, x must be positive and therefore the least possible value of x is:

[tex]x = 3[/tex]

Step-by-step explanation:

Answer:

I think the answer is 4 1/2 out of 30 chance.

Step-by-step explanation:

The probability of selecting two solid chocolates in a row is 4/145.

To calculate the probability of selecting two solid chocolates in a row, we need to consider the probability of selecting a solid chocolate on the first draw and the probability of selecting a solid chocolate on the second draw, given that a solid chocolate was selected on the first draw.

There are a total of 30 chocolates, with 9 solid chocolates. Therefore, the probability of selecting a solid chocolate on the first draw is 9/30.

After eating the first chocolate, there are now 29 chocolates left in the box, with 8 solid chocolates remaining. So the probability of selecting a second solid chocolate is 8/29.

Since the two events are independent, we can multiply the probabilities of each event to find the probability of both events occurring:

Probability of selecting two solid chocolates = (9/30) * (8/29) = 4/145.

Step-by-step explanation:

The building's dimensions would be 22.5 inches by 12.5 inches on the drawing when the scale of 1 inch represents 10 feet.

The dimensions of the building you have mentioned are 225 feet by 125 feet. Given the scale of 1 inch represents 10 feet, we can calculate the dimensions of the building on the drawing by dividing each dimension of the building by the scale factor.

So, for the first dimension: 225 feet divided by 10 (scale factor) equals 22.5 inches. For the second dimension, 125 feet divided by 10 equals 12.5 inches.

Therefore, the dimensions of the building on the drawing would be 22.5 inches by 12.5 inches.

Answer: e = 10

Step-by-step explanation: 9e + 4 = -5e + 14 + 13 e

Now lets bring the variables and numbers on a different side

Remember that when the numbers go to the other side the sign changes

so 4 - 14 = -9e + 13e -5e

-10 = -e

10 = e

if plug in both equations on a graph then you will see that when e = 10 the lines meet at 94.

Answer:

[tex]e=10[/tex]

Step-by-step explanation:

[tex]9e+4=-5e+14+13e[/tex]

Simplify both sides by combining [tex]-5e+13e[/tex] :

[tex]9e+4=8e+14[/tex]

Isolate the variable e. Subtract  8e from both sides:

[tex]9e-8e+4=8e-8e+14\\\\e+4=14[/tex]

Subtract 4 from both sides:

[tex]e+4-4=14-4\\\\e=10[/tex]

They're same side interior angles because since it's a parallelogram, the lines are parallel, and in this case, AB and CD are the parallel lines, AD is the transversal, and therefore, x and 115 are same side interior.

Same side interior angles are supplementary so x + 115 = 180

x = 180 - 115 = 65

complete question:

The volume of the sphere is 500/3 π cubic units. What is the value of x?  

x = radius

Answer:

x = 5 units

Step-by-step explanation:

The volume for a sphere can be represented as follows

volume = 4/3πr³

volume = 500/3 π

x = radius

volume = 4/3πx³

500/3 π = 4/3 × π × x³

multiply both sides by 3/4

500/3 × π × 3/4 = π × x³

125π = πx³

divide both sides by π

x³ = 125π/π

x³ = 125

cube root both sides

x³ = ∛125

x = 5 units

Step-by-step explanation:

The missing angle is ...

  180° -60° -75° = 45°

Knowing that, the Law of Sines can be used to find the side opposite the 75° angle.

  ?/sin(75°) = 900 km/sin(45°)

  ? = (900 km)sin(75°)/sin(45°) ≈ 1229.423 km

Answer: (0.2215, 0.5785)

Step-by-step explanation:

Given, Trinity takes a sample of 50 songs and finds that 20 are by a female artist.

Let p be the proportion of songs on her phone by a female artist.

Then , the 99% confidence interval for p would be :-

[tex]\hat{p}\pm z\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}[/tex]  ...(i)

As per given , Sample size : n= 50

Sample proportion of songs on her phone by a female artist. [tex]\hat{p}=\dfrac{20}{50}=0.4[/tex]

For 99% confidence level , critical z-value =2.576

Substituting values in (i), we get

[tex]0.4\pm 2.576(\sqrt{\dfrac{0.4(1-0.4)}{50}})\\\\=0.4\pm 2.576\sqrt{0.0048}\\\\\approx0.4\pm0.1785\\\\=(0.4-0.1785,\ 0.4+0.1785)\\\\=(0.2215,\ 0.5785)[/tex]

Hence, a 99% confidence interval for the proportion of songs on her phone by a female artist : (0.2215, 0.5785)

The correct answer is B) Yolanda should have found the volume by multiplying 8 by Four-thirds.

Yolanda incorrectly used the formula for volume of a sphere instead of the correct formula. The volume of a sphere is V = (4/3)πr³, not V = four-thirds(8) cubed.

By using the correct formula, Yolanda should have multiplied 8 by four-thirds to find the volume of the sphere, resulting in a different value.

Answer:

Assuming that the die has sides that are equal and that the sides are numbered 1 to 666 (since there are 666 sides), then the probability of rolling a 555 and flip a heads is 1/1,332.

Step-by-step explanation:

Probability of flipping a heads: 1/2

Probability of rolling a 555: 1/666

Multiply the two probabilities to get your probability for rolling both.

1/2 times 1/665 is 1/1,332.

Step-by-step explanation:

8^2 + x^2 = 10^2

64 + x^2 = 100

x^2 = 36

x = 6 (-6 can't be a length)

Answer:

The Answer Is 6

Step-by-step explanation:

By Pythagoras Theorem

(AC)^2 = (AB)^2 + (BC)^2

(AB)^2 = (AC)^2 - (BC)^2

(AB)^2 = (10)^2 - (8)^2

(AB)^2 = 100 - 64

(AB)^2 = 36

(AB) = 6

Answer:

Step-by-step explanation:

per bag

9/3=3 lollipops

6/3=2 peanut butter cups

3/3=1 chocolate

then add them together to get 6

Answer: 6 pieces of candy

Step-by-step explanation:

Assuming lollipops, peanut butter cups, and chocolate are wanted in 3 bags, we would add all the candy together.

9+6+3=18

We have a total of 18 candies. Since we have to split the candy into 3 bags, you would divide 18 by 3.

18/3=6

There will be 6 pieces of candy in each bag.
