Answer:

Step-by-step explanation:
The missing parameters are:
--- population
--- population mean
-- population standard deviation
Required

First, calculate the sample standard deviation




Next, calculate the sample mean 

So:

So, we have:



Calculate the z score




So, we have:

From the z table

So:

subtract 4x from both sides
-2y=14-4x
divide each side by -2
y=2x+7
Answer:
dy/dx = x=-1
Step-by-step explanation:
by use of intergration to get the values of yaxis and x axis,,the values are -2, -4,
Answer:
m∠WUV = 23°
Step-by-step explanation:
m∠TUW and m∠WUV must add up to m∠TUV
Step 1: Set up equation
m∠TUW + m∠WUV = m∠TUV
8x + 7 + 4x - 1 = 78
Step 2: Solve for <em>x</em>
12x + 6 = 78
12x = 72
x = 6
Step 3: Find m∠WUV
m∠WUV = 4x - 1
m∠WUV = 4(6) - 1
m∠WUV = 24 - 1
m∠WUV = 23°
