250 miles ÷ 4.5 hours = 56 mph (rounded from 55.55555)
The sample proportion is a point estimate of the population proportion. Therefore we need to convert the given percentage to a decimal fraction to find the best point estimate.
35/100 = 0.35
The best point estimate is 0.35.
The arithmetic sequence of 161,147,133,119
Compute the general progression formula of 161,147,133,119 d=-14, a↓n+175
Compute ᵃ₂₂ = -133
Answer:
Step-by-step explanation:
So since triangle jkl and wyz are similar angles j and w must equal each other, angles k and y must equal each other, and angles l and z are equal. So to find x just set 4x-13 equal to 71
4x-13=71
add 13 to both sides to cancel the -13 from the left
4x=84
and divide both sides by 4 to cancel the 4 on the left
x=21
