find a perimeter of a rectangle with a length of 665 feet and width of 421 feet. Draw your model and solve.

Tomtit [17]

Well the formula for the perimeter of a rectangle is 2w+2l
w=width
l=length
So it is 2(665)+2(421)=2172

What is the volume of a rectangular prism with the dimensions: base 2 3 /8 cm, height 1 1/3 cm, and length 3 3 /4 cm?

Ugo [173]

Answer: 11.84 cm³

Step-by-step explanation:

1. Let's rewrite the given dimensions (expressed as mixed numbers) as decimals. Divide the numerator by the denominator of the fractional part and add the result to whole number part. Then:

$2^\frac{3}{8}cm=(2+0.375)cm=2.375cm\\1^\frac{1}{3}=(1+0.333)cm=1.333cm\\3^\frac{3}{4}=(3+0.75)cm=3.75cm$

2. Then, to calculate the volume you must multiply its dimensions. Therefore, you obtain the following result:

$V=2.375cm*3.75cm*1.33cm\\V=11.84cm^{3}$

Suppose a large population has a mean μand standard deviation σ, and a simple randomsample of size nis taken. The sampling distr

My name is Ann [436]

Answer:

(d) μ and σ²/n

Step-by-step explanation:

In a sampling distribution of sample means, the mean is equal to the population mean, which is μ.

The standard deviation of the sampling distribution of sample means is given by

σ/√n.

The variance of a distribution is the square of the standard deviation; this means the variance of the sampling distribution of sample means would be

(σ/√n)² = σ²/(√n)² = σ²/n
