The cruising speed of a prototype jet is approximately mach 0.92, meaning 0.92 times the speed of sound. if the speed of sound at cruising altitude is approximately 295 m/s, what is the cruising speed of the prototype jet in miles per hour? a) what is mach 0.92 in m/sec?
(b) sahill, who has a resting heart rate of 68 bpm, increased it to 119 bpm. by what percent did he increase his resting heart rate?

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

"a" determine whether sage found the correct quotient. show your work

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

i would say b) is your answer
