Question:

The scatter plot shows the maximum noise level when different numbers of people are in a stadium. The linear model is given by the equation y=1.5x + 22.7 where y represents maximum noise level and x represents the number of people, in thousands, in the stadium.​​​​​​

A sports announcer states that there are 65,000 fans in the stadium. Estimate the maximum noise level. Is this estimate reasonable? Explain your reasoning.

Answer:

y  = 97522.7

Step-by-step explanation:

Given

y = 1.5x + 22.7

x = 65000

Required

Find y

Substitute 65000 for x in the given equation

y  = 1.5 * 65000 + 22.7

y  = 97500 + 22.7

y  = 97522.7

<em>It is reasonable because as the population increases, the noise level also increases</em>

Which angle measures are correct? Select three options,
masya89 [10]

Answer:

m∠W = 125°

m∠X = 55°

m∠Z = 55°

Step-by-step explanation:

The shape is parallelogram WXYZ. m∠Y = 125.

A parallelogram is a quadrilateral shape in which both opposite sides and opposite angles are equal to each other. The diagonals of a parallelogram bisect each other. Also consecutive angles in a parallelogram are supplementary.

Therefore in parallelogram WXYZ:

m∠Z + m∠Y = 180° (Consecutive angles in a parallelogram are supplementary)

m∠Z + 125 = 180

m∠Z = 180 - 125

m∠Z = 55°

m∠W = m∠Y (Opposite angles are equal)

m∠W = 125°

m∠W + m∠X = 180° (Consecutive angles in a parallelogram are supplementary)

m∠X + 125 = 180

m∠X = 180 - 125

m∠X = 55°

Find the midpoint M of the line segment joining the points P = (-4, 6) and Q = (8, -4).​
mrs_skeptik [129]

Answer:

M=(2,1)

Step-by-step explanation:

The mid points is half the distance of the x and y values so

-4 and 8 are 12 apart so 12/2=6 so -4+6=2

so the x value of M is 2

same for the y value 6 and -4 are 10 apart 10/2=5 and 6-5=1 so

so the y value of M is 1 so

M=(2,1)

Price of an article is 400 and sold with discount including 13% vat at 339 find discount rate
zvonat [6]
To add 13% vat we can multiply by (100%+13%) = 113% = 1.13
To remove 13% vat divide by 1.13
339 / 1.13 = 300 the discounted price.
The amount of discount = 400 - 300 = 100
Discount rate = 100 / 400 = 1/4 = 25%

The point (0, 0) is a solution to which of these inequalities?
strojnjashka [21]

The point (0, 0) is a solution to which of these inequalities are satisfied. so option B. y-7<2x-6is the only correct answer.

<h3>What is inequality?</h3>

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

The point (0, 0) is a solution to which of these inequalities are satisfied.

A. y+7<2x - 6

      7 < -6

So, it is incorrect.

B. y-7<2x-6

      -7 < -6

So, it is correct.

C. y-6<2x-7

         -6 < -7

So, it is incorrect.

D. y+7<2x+6

7 < 6

So, it is incorrect.

Hence, option B is the only correct answer.
