Let r be the binomial random variable corresponding to the number of people that will live beyond their 90th birthday, r ≥ 15.

We want to find
P(r ≥ 15)
using the normal approximation given 625 trials and a probability of a 4.4% success on a single trial.

360/29

step-by-step explanation:

there is nothing below so i cannot

step-by-step explanation:

the answer is:

the answer is:

to solve the problem, we need to remember the quotient of power property, it's defined by the following relation:

if we have a quotienf of powers that have the same base, we need to keep the same base and subtract the exponent of the denominator power to the exponent of the numerator power.

so, we are given the expression:

then, calculating we have:

hence, the answer is:

have a nice day!

after 1 year: 221 deer

step-by-step explanation:

30% of 170 is 51. 170+51=221
