Answer:
0.5532
Step-by-step explanation:
P( 31<X<35.7)
P(X>31)= P(Z>(31-μ)/σ)
= P(Z>(31-34.6)/2.8)
= P(Z> -1.2857)
P(X<35.7)= P(Z<(35.7-μ)/σ)
= P(Z<(35.7-34.6)/2.8)
=P(Z< 0.392857)
From z-distribution table
P(Z< -1.29)= 0.09853
p(Z< 0.39) = 0.65173
P( 31<X<35.7)= P(Z<0.39)- P(Z<-1.29)
= 0.65173- 0.09853
=0.5532
She should use the spinning wheel because its a 2/12 chance, with a wheel its a 1/6 chance.
Answer:
v = -2
Step-by-step explanation:
-9v – 9 = -27
add 9 to each side
-9v – 9+9 = -27+9
-9v = -18
divide by -9
-9v/-9 = -18/-9
v = 2
Answer:
0.5 repeating
Step-by-step explanation:
you would simply divide 5 by 9 to find the answer.
