Answer:
Step-by-step explanation:
Given that the sitting back-to-knee length for a group of adults has a normal distribution with a mean of mu equals 22.1 in. and a standard deviation of sigma equals 1.2 in.
We have to find values of x such that
and
a=2.33 and b =-2.33 as z values
Let us convert to X values
i.e. values below 19.304 and above 25.496
Hence for x below 19.304 and above 25.496 are significantly low and high.
24.2 length is not significantly high.

Answer: Yes we have a direct proportional relationship</h3><h3>constant of proportionality = 8</h3>
equation is y = 8x
=============================================
Explanation:
Divide each x and y pair like so: y/x
If we get the same result each time, then we have a direct proportion.
y/x = 32/4 = 8
y/x = 56/7 = 8
y/x = 96/12 = 8
Each time we get the same result 8, which is the constant of proportionality. The table does show a direct proportional relationship. The equation is y = 8x which is in the form y = kx. The k value is the constant of proportionality. So k = y/x.

For 1 pie , she needs 2 cup
so , for 4 pie , she needs 8 cups
hope it is clear;)
