Answer:5/1
Step-by-step explanation:5 times 1 is 5 so for every female it’s 5 male
It realistically could be any number based on the person but the most likely answer is 40 hours.
8 in x 10 in because you multiply each length by the Scale factor which is 2
Step-by-step explanation:
(6+r)^2 = 81 + r^2
36 + 12r+ r^2 = 81 + r^2
12r = 81-36 = 45
r = 15/4 = 3.75
Confidence interval is given by the formula
x ⁺/₋ z* ( σ/ (√n) )
Where:
x = the sample mean = 130
z* = the z-value for 90% confidence = 1.645
σ = standard deviaton = 7
n = sample size = 145
Substituting these values into the formula gives:
130 ⁺/₋
130 ⁺/₋ 0.956
So the interval is in between (130 - 0.956) and (130 + 0.956)
