Answer:
3/4=75%
Step-by-step explanation:
the prob is the shaded area divided by the full Rect area
the Rect area is 3*2, and the shaded area is 3*2-1*1.5=4.5
such that the probability is 4.5/6=3/4
Answer:
P (z) = -1.5094
Step-by-step explanation:
We have to find P-value (that means we have to calculate the test value to evaluate a proportional hypothesis
From problem statement
P₀ = 0,44 44 % from publisher report
The claim :
350 = n random sample
P = 0,40 40 %
To calculate P value
P ( z ) = ( P - P₀ ) / √(P₀*Q₀)/n
then P ( z ) = - 0.04 / √(0,44)(0,56)/350 P(z) = - 0.04/0,02
P (z) = -1.5094
It would take them 12 minutes to finish 1 mile.
60 minutes/5 miles= 12 minutes
