Answer:399
Step-by-step explanation:
Sp= 100-5/100*420
95*42/10= 399

The answer would be 66.30
Answer:
Step-by-step explanation:
Hello!
Be X: air pressures of properly inflated sports balls.
<em>Average recommended psi Tolerance(pounds per square inch)</em>
<em>Soccer ball 12.05 ±3.55</em>
<em>Basketball 8.00 ±0.5 </em>
<em>Volleyball 4.44 ±0.18</em>
Each recommendation is expressed like the "average air pressure" ± "standard deviation of the recommended air pressure" so if you express it in inequality it will be:
X[bar]-S ≤ X ≤ X[bar]+S
So for each ball type, you can write it as:
<u>Soccer ball</u>
12.05-3.55 ≤ X ≤ 12.05+3.55
8.5 ≤ X ≤ 15.6
<u>Basketball</u>
8.00-0.5 ≤ X ≤ 8.00+0.5
7.5 ≤ X ≤ 8.5
<u>Volleyball</u>
4.44-0.18 ≤ X ≤ 4.44+0.18
4.26 ≤ X ≤ 4.62
I hope this helps!
When the events are independent, the probability of both is the product of the probabilities of the individual events.
P(A∩B) = P(A)×P(B) = 0.7×0.8 =
D. 0.56
