I think it’s 90% cuz it’s 45/50 therefore 90/100
Answer:
For a height of 66 inches, Z = 0.65.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The average height was about 64.3 inches; the SD was about 2.6 inches.
This means that
66 inches:
The z-score for a height of 66 inches is:
For a height of 66 inches, Z = 0.65.

Step-by-step explanation:
Answer:
c) (
d) (
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the binomial expression
(
Multiply
( 36 + 6√12 -6√12 -(√12)²)
= ( 36 -12)
= 24
c) (
<u><em>Step(ii):- </em></u>
Given that the binomial expression
(
Multiply
= 9 - 3√8 + 3√8 -(√8)²
= 9 - 8
= 1
d) (
1. Line 3 is the first error. In order to get rid of the 25, you add it to both sides, not subtract. So, your answer is B.
2. Line 1 because it says in the question "4
less than a number" and the equation adds 4, instead of subtracting. Your answer is A.
3. Line 4. To get rid of the 6 in front of 6x, you have to divide by it, but instead they multiply. So, your answer is C.
4. To solve this, you will use the distributive property first:
Turns into:
Get rid of the 12:
Divide by 4:
Your answer is B.
5. You have to set it up:
Just solve for x:
Multiply both sides by 3 to isolate x:
Your answer is B.
