Answer:

a. We get 56 heads out of 100 tosses.
We will use one sample proportion test
x = 56
n = 100



Formula of test statistic =

refer the z table for p value
p value = 0.8849

p value of part B is less than Part A because part B have 10 times the number the tosses.
Answer: 3:1
Step-by-step explanation:
They are all perfect squares
(9x+2)(9x+20
(9x+2)^2
-66 is the 27th term.
You have a function in terms of n. Recall that n is the nth term in the sequence.
Substitute n = 27 into the equation to find the 27th term.
a₂₇ = -10 + (27 + 1)(-2) = -10 + (28)(-2) = -10 - 56 = -66
