Answer:
0.003
Step-by-step explanation:
By formula we know that:
z (x) = (x - m) / [sd / sqrt (n)]
where x is the value we want to know (60,000), m is the mean (63500), sd is the standard deviation (6100) and n is the sample size (35).
Replacing we have:
z (60000) = (60000 - 63500) / [6100 / sqrt (35)]
z = -3.39
If we look in the normal distribution table (attached), we have that the probability is 0.0003.
Answer:
C
Step-by-step explanation:
Supplementary angles because their sum is 180 degrees
108 in^2
Because,
As you can see, inside the trapezoid has the square.
AND
A = lw
and the length is 9 and width 12.
9 * 12 = 108

Answer:
40 exhibits dose the aquarium have.
Second model represent the problem.
Step-by-step explanation:
let number of exhibits dose the aquarium have = x
According to given condition;
90% of x = 36
(90/100) x = 36
x = (36×100)/90
x = 40
40 exhibits dose the aquarium have.
Second model represent the problem.
