Please help, 20 points.<br> Perimeter :)
djyliett [7]

Answer:

<h2>D. (42 - 2x)(32 - 2x) = 900</h2>

Step-by-step explanation:

<em>Look at the picture.</em>

The dimensions of the picture:

(42 - 2x)in × (32 -2x)in

The formula of an area of a rectangle:

A = l · w

l - length, w - width

Substitute l = (42 - 2x), w = (32 - 2x) and A = 900

(42 - 2x)(32 - 2x) = 900

A pizza delivery shop averages 20 minutes per delivery with a standard deviation of 4 minutes. What is the probability that a pi
Orlov [11]
We have the mean, μ = 20 and the standard deviation, σ = 4

X ≈ N(20, 4²)

We want P(X<15)

Standardising gives

P(X<15) = P(Z<\frac{15-20}{4})
P(X<15) = P(Z< -1.25) ⇒ When the value of the z-score is negative, we will read the value of z<1.25 on the z-table then subtract the answer from 1

P(X<15) = 1 - P(Z<1.25)
P(X<15) = 1 - 0.8944
P(X<15) = 0.1056

Hence, the probability that pizza takes less than 15 minutes to be delivered is 0.1056 = 10.56%

Round each number  to the nearest tenth what is the best estimate for the answer to 38.94+65.43
mel-nik [20]
38.94 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down

38.94

The number is 4, so we round down. 38.94 becomes 38.9

65.45 rounded to the nearest tenth. To know if we should round up or down, we look to the number in the hundredths place. If that number is 5 or greater, we round up. If the number is 4 or less, we round down.

65.43

The number is 3, so we round down. 65.43 becomes 65.4

38.9+65.4= 104.3

If you were to estimate 38.94+65.43, we round the number to numbers that we can easily calculate in our head. 38.94+65.43 becomes 40+65

40+65=105
