when a number is added at the end it results in a vertical transformation
percent means out of 100
35/100
divide the top and bottom by 5
7/20
Answer:
d. She should reject the null hypothesis because p < 0.10.
Step-by-step explanation:
We have a t statistic, so let's solve for the P-value on our calculators. (tcdf on a TI-84 calculator is 2nd->VARS->6.)
tcdf(left bound, right bound, degrees of freedom)
- Our left bound is t=1.457.
- Our right bound is infinity, because we're interested in the hypothesis µ>40 mg/dL. We use 999 to represent infinity in the calculator.
- Our degrees of freedom is n-1 = 15-1 = 14.
tcdf(1.457,999,14) = .084
.084 < P-value of .10, so we reject the null hypothesis.
Answer: h(f(x)) = 2x-11
Step-by-step explanation:
h(x) = 2x + 3
f(x) = x-7
h(f(x)) = 2(x-7) + 3
h(f(x)) = 2x-14 + 3
h(f(x)) = 2x-11
