Step-by-step explanation:
Given that an electrical power company is looking to expand into a new market. Before they commit to supplying the new area with electricity, they would like know the mean daily power usage for homes there.
Population std deviation = 
Sample size =
STd error of sample mean = 
Margin of error for 95% would be Critical value ( std error)
Here since population std dev is known we can use Z critical value= 1.96
Sample size should be atleast 385
Answer:
-4/3 = y
Step-by-step explanation:
-1/2 = 3/8y
Multiply each side by 8/3 to isolate y
-1/2 * 8/3 = 3/8y * 8/3y
-8/6 =y
-4/3 = y
Answer:
A=174
Step-by-step explanation:
Step 1: Separate the figure into two separate shapes, a triangle and a square
Step 2: Find the dimensions of the triangle and square.
Square - l=12 w=12
Triangle - h=5, b=12. (The height was found by subtracting the length of the square (12) from the total length (17).
Step 3: Solve by using formulas
A=(5)(12)/2=30
A=12*12=144
Step 4: Add the parts together
144+30=174
A=174
