Answer:
yes
Step-by-step explanation:
0.731 < p < 0.775
We have a sample proportion of 753/1000 = 0.753
We need to construct a 90% confidence interval for the population proportion. Since n > 30, we use the corresponding z-value of 1.645.
See attached photo for the formulas and construction of the confidence interval.
14w+26
So use PEMDAS, distribute, and combine like terms
14w+21+5
then
<span>P(X=0) = 3C0 (0.72^0)(0.28^3) = 0.022P(X=1) = 3C0 (0.72^1)(0.28^2) = 0.169P(X=2) = 3C0 (0.72^2)(0.28^1) = 0.435P(X=3) = 3C0 (0.72^3)(0.28^0) = 0.373 </span>
<span>Notice how they all equal 1.</span>
x = -2
Steps:
10x-10(-4)=10
15x+10*4=10
15x+40=10
15x+40-40=10-40
15x=-30
