Answer:

2 inches

Step-by-step explanation:

First, find out how many times 3 feet goes into 24 feet. You should get 8 times. Then, multiply 1/4 times 8, and the answer should be 2. For every 2 inches, on the blueprint, it will be 24 feet in real life. Hopefully this helps!

Answer:

The value of the test statistic is z = -1.5

Step-by-step explanation:

The formula for the test statistic is:

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the statistic, \mu is the mean, \sigma is the standard deviation and n is the number of observations.

In this problem, we have that:

\mu = 20, X = 17, \sigma = 6, n = 9

So

z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

z = \frac{17 - 20}{\frac{6}{\sqrt{3}}}

z = -1.5

The value of the test statistic is z = -1.5

Can someone help me? I'm trying to find the slope form of 4x + 2y = 4.
Neporo4naja [7]
Here, Equation: 4x + 2y = 4
Divide the equation by 2, 
2x + y = 2
y = -2x + 2

Now, compare the equation with y = mx + c
Here, slope (m) = -2

In short, Your Answer would be -2

Hope this helps!
