Answer:

false

Step-by-step explanation:

6x - 6 = 6x -6

to get x by itself you would have to divide by 6

6x / 6 = x

There is a chowder eating contest in a small New England town. The distribution of the amount of chowder consumed is bell-shaped

Y_Kistochka [10]

Answer:

Interval ( 24 ; 40 ) has 136 participants

Interval ( 16 ; 40 ) has 163 participants

Step-by-step explanation:

Normal distribution.

As variance is 64 then standard deviation is σ = 8

And mean μ₀ = 32

We can see that μ₀ ± σ is 32 ± 8

The interval ( 32- 8 ; 32+8 ) is ( 24 ; 40 )

By empirical Rule we know that μ₀ ± σ contains 68% of the population then 200*0,68 = 136

The number of participants between 24 and 40 is 136

By symmetry of these 136 half of them are between 32 and 40 ( 136/2 = 68 ) ( between mean and 40 )

Now in the interval ( 16 ; 40 ) we note that 16 is 32 - 16 = 16 or μ₀ - 2σ

And again by empirical rule μ₀ ± 2σ has 95 % of the population that means 200*0.95 = 190 and by symmetry 190/2 95 are between μ₀ - 2σ, therefore

95 people are between μ₀ - 2σ or between ( 16 ; 32 ) and between ( 32 ; 40 ) there are 68 people then

The interval ( 16 ; 40 ) has 95 + 68 = 163 participants

Would do anything for the answer to this question

<u>Given</u>:

The length of the entire rectangle is 10x + 7.

The width of the entire rectangle is 6x.

The length of the unshaded rectangle is 4x - 5.

The width of the unshaded rectangle is 2x.

We need to determine the area of the shaded region of the rectangle.

<u>Area of the entire rectangle:</u>

The area of the entire rectangle can be determined using the formula,

$A=length \times width$

Substituting the values, we have;

$A_1=(10x+7)(6x)$

$A_1=60x^2+42x$

Thus, the area of the entire rectangle is 60x² + 42x

<u>Area of the unshaded rectangle:</u>

The area of the unshaded rectangle can be determined using the formula,

$A=length \times width$

Substituting the values, we have;

$A_2=(4x-5)(2x)$

$A_2=8x^2-10x$

Thus, the area of the unshaded rectangle is 8x² - 10x

<u>Area of the shaded region of the rectangle:</u>

The area of the shaded region of the rectangle can be determined by subtracting the area of the entire rectangle by the area of the unshaded rectangle.

Thus, we have;

$A=A_1-A_2$

Thus, we have;

$A=60x^2+42x-(8x^2-10x)$

$A=60x^2+42x-8x^2+10x$

$A=52x^2+52x$

$A=52x(x+1)$

Thus, the area of the shaded region of the rectangle is 52x(x + 1)
