-15=-15
Since both sides equal, they are infinitely many solutions
D) infinitely many solutions
Since only 2 sides are equal (not 3), this is an "isosceles triangle."
25$ because if you bout something that was 25$ 25$ off would make it free but 25% off would make it 6.25
Answer:
The correct answer is C
Step-by-step explanation:

Given:
population mean, μ =135
population standard deviation, σ = 15
sample size, n = 19
Assume a large population, say > 100,
we can reasonably assume a normal distribution, and a relatively small sample.
The use of the generally simpler formula is justified.
Estimate of sample mean

Estimate of sample standard deviation


to 5 decimal places.
Thus, using the normal probability table,





Therefore
The probability that the mean weight is between 125 and 130 lbs
P(125<X<130)=0.0731166-0.0018308
=
0.0712858
