adoni [48]

The area of the metal strips:
A = L * W , where L stays for length and W stays for wirth.
A = 11 ft * 2 ft ;
A = 22 ft^2.
If it costs $6 per foot:
Total cost = 22 * 6 = $132.
Answer: The total cost of a metal strip is $132.

Use compatible numbers to estimate the quotient <br> 252÷3

ICE Princess25 [194]

Answer:

The value of the given expression is 84.

Step-by-step explanation:

The given expression is

$\frac{252}{3}$

The number 252 can be written as 240+12, because 24 can easily divisible by 3.

The compatible numbers are 240 and 12

$\frac{252}{3}=\frac{240+12}{3}$

$\frac{252}{3}=\frac{240}{3}+\frac{12}{3}$

$\frac{252}{3}=80+4$

$\frac{252}{3}=84$

Therefore the value of the given expression is 84.

Assume that a set of test scores is normally distributed with a mean of 70 and a standard deviation of 10. In what percentile is

vlabodo [156]

Given:
μ = 70, the mean
σ = 10, the standard deviation

The random variable is x = 65.
Calculate the z-score.
z = (x - μ)/σ = (65 -70)/10 = - 0.5

From standard ables, obtain
P(x<5) = 0.3085 ≈ 30%
The score of 65 is in the 30th percentile.

Answer: 30th
