Answer:
Step-by-step explanation:
ah, probability, so the std. deviation is 2 MPH, so that means to get from the mean.. or average speed of 94, he'll have to vary by 3 std. deviations or 6 MPH to hit 100
99.7% of throws fall into that area of with in 3 std. deviations so that means
0.3% fall outside also , 1/2 of those will 3 std. deviations slow while the other half is fast
so
0.15% will be 100 or faster.... not many
Answer:
15) 37 16) -5x+13=-112, x=25 23) l=38, w=19
Step-by-step explanation:
15) l=5w+2, 2l+2w=88
2(5w+2)+2w=88
12w+4=88
w=7, l=37
16a) -5x+13=-112
16b) x=25
23) l=2w, 2l+2w=114
2l+l=114
l=38, w=19
