Answer:

<h2>27 times</h2>

Step-by-step explanation:

The formula of a volume of a pyramid:

V=\dfrac{1}{3}BH

<em>B</em><em> - base area</em>

<em>H</em><em> - height</em>

<em />

We have two square pyramids.

The bases are squares. The formula of an area of a square with sides <em>s</em> :

A=s^2

Pyramid A:

<em>s = 12in, H = 8in</em>

B_A=12^2=144\ in^2\\\\V_A=\dfrac{1}{3}(144)(8)=384\ in^3

Pyramid B:

<em>s = 36in, H = 24in</em>

B_B=36^2=1296\ in^2\\\\V_B=\dfrac{1}{3}(1296)(24)=10368\ in^3

Calculate the quotient:

\dfrac{V_B}{V_A}=\dfrac{10368}{384}=27

In your random sample of 25 Chips Ahoy bags, you find a mean of 985 chips per bag, with a standard deviation of 10 chips. Run a
stealth61 [152]

Answer:

The p -value is less than 0.001.

Step-by-step explanation:

Given information:

Sample size = 25 chips

Sample mean = 985

Sample standard deviation = 10

Let as assume that sample is distributed normally.

The formula for test statistic

t=\frac{\overline{x}-\mu}{\frac{s}{\sqrt{n}}}

where,

\overline{x} is sample mean

μ is population mean.

s is sample standard deviation.

n is sample size.

The value of test statistic is

t=\frac{985-1000}{\frac{10}{\sqrt{25}}}

t=\frac{985-1000}{\frac{10}{\sqrt{25}}}

t=-7.5

The p-value is

p=2\times p(t

Therefore the p -value is less than 0.001.

What is the range of the function y = x 2?
garik1379 [7]

Answer:

The range of the function y = x2 is all real numbers, y, such that y ≥ 0. In the case of the function y = x2, the domain consists of all real numbers, because there is no number that, when plugged in for x into x2, would create an undefined expression.
