To find the quotient you do 6/ (-1/2). You keep, change, flip when dealing with fractions.
Answer:
The largest average score the researcher should consider is 117
Step-by-step explanation:
Mean = xbar = 114
Standard deviation = σ = √(variance) = √(400) = 20
Let The standardized score that corresponds with lower 56% be x'.
Let the z value that corresponds to the probability of 0.56 be z'
We need to obtain the z value that corresponds with a Probability of P(z ≤ z') = 0.56
using the normal probability distribution table,
z' = 0.151
P(z ≤ z') = P(z ≤ 0.151) = 0.56
z' = (x' - xbar)/σ
0.151 = (x' - 114)/20
x' = 117
Answer:
35 feet or 11
or ≈11.67 yards.
Step-by-step explanation:
A yard is 3 feet.
35÷3=
11.66... (6 continues forever) or 11
(11 2/3) yards
A compass and straightedge are supposed to be part of the required equipment for your class. You are expected to use them here. Your assignment paper should be complete with pencil marks and holes from the compass point. Nobody can do it for you on-line.
Here is a picture of the first one worked. The remaining ones are just like it. The whole assignment should take about 3 minutes, tops.
