Answer:
No
Step-by-step explanation:
It is a solution to the first equation, but not the second equation.
34.60 or 35
Depends on what to round, tenths or hundreds....
Answer:
36h + 75 < 1200
solve:
36h + 75 = 1200
36h = 1125
h = 1125 divided by 36 = 31.25.
Therefore, Traci has to dance a minimum of 31.25 hours to raise $1200
Answer:
29
Step-by-step explanation:
Answer:
a. 0.5
Step-by-step explanation:
We know that X follows normal distribution with
mean=75
standard deviation=8


P(0<Z<∞)
The area under the normal curve is 1 and the (0<Z<∞) =0.5 and (-∞<Z<0) =0.5
So, P(0<Z<∞)=0.5
Hence the P(X ≥ 75)=0.5
