with that template in mind, let's see, it went to the right 2 units, and then up 3 units.
that simply means, C = -2, D = 3.

Answer:
<u>36 in²</u>
Step-by-step explanation:
<u>Area of the figure</u>
- Area (small rectangle) left + Area (big rectangle) right
- 3 x (6 - 4) + 5 x 6
- 3 x 2 + 30
- 6 + 30
- <u>36 in²</u>
Answer:
The word problem is "How many $25 are there in $125?"
<em></em>
Step-by-step explanation:
Given
Required
Write a word problem for the expression
We start by solving the given equation
Divide both sides by $25
This implies that there are 5, $25 in $125
<em>Hence; The word problem is "How many $25 are there in $125?"</em>
Answer:
1. The probability that x will be more than 25 is 0.6305.
2. The 55th percentile is 26.38.
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.
Mean 26 and standard deviation 3.
This means that
1 Find the probability that x will be more than 25.
This is 1 subtracted by the p-value of Z when X = 25. So
has a p-value of 0.3695.
1 - 0.3695 = 0.6305.
The probability that x will be more than 25 is 0.6305.
2 Find the 55th percentile of x.
This is X when Z has a p-value of 0.55, so X when Z = 0.125.
The 55th percentile is 26.38.
