Answer:
5+9+-23
Step-by-step explanation:
137 - 16X = Y
Since Lorraine is picking blackberries in her backyard at a rate of 15 berries per minute, and after 16 minutes of picking, there are still 137 blackberries left to pick, to determine an equation that models how many berries are left (y) after x minutes of picking, the following calculation must be performed:
137 - 16X = Y
Thus, for example, after 5 minutes the calculation would be as follows:
- 137 - 16 x 5 = Y
- 137 - 80 = Y
- 57 = Y

Answer:
D. a = 60 and b = 58.8
Step-by-step explanation:
Z-score:
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.
Z-score for data point a is 0.
This means that a is the mean, that is, a = 60.
The z-score for data point b is -0.4.
This means that b must be a value below the mean, that is, a value below 60.
The option that satisfies a = 60 and b < 60 is option D, which is the answer.
Answer:
The only way of getting to 10 using 2x it should mean that x = 5
2 * 5 = 10
The calculation of the expression “four times as large as 124+645” end up in 1141.
<u>Step-by-step explanation:</u>
- The question is asked to Express the calculation “four times as large as 124+645”.
- The given statement can be written in the expression form to perform the calculations.
Here, the phrase 'four times' represents the multiplication of 4.
⇒ “four times as large as 124+645” = 4(124) + 645
So, the first step is to multiply 4 with 124.
⇒ 4 × 124
⇒ 496
The expression is now modified as “496+645"
We know that, the final result is the addition of the two numbers 496 and 645 which is calculated as
⇒ 496+645
⇒ 1141
Therefore, the calculation of the expression “four times as large as 124+645” end up in 1141.
