Answer:
The value of x is 4
Step-by-step explanation:
y = 2.5x + 65; y = 75
Now, Substitute
y = 2.5x + 65
75 = 2.5x + 65
75 – 65= 2.5x + 65 – 65
10 = 2.5x
2.5x = 10
2.5x/2.5 = 10/2.5
x = 4
Thus, The value of x is 4

Hey there!
Answer:
_____________________
Step-by-step explanation:
There are two different kind of ways in order to complete this real world scenario, but, we'll start with the most easiest and basic.
Both equal 176, as the problem stated out. Then we simply plug it in with the information that was brought out.
Therefore, we know see how we got our answer as 520 bags for each kind of mulch. I hope this helps you!
Part A.
32'1/4÷1/8=258
1 team has 8 people, we currently have 32'1/4 teams, so how many people do we have? We have 258 people.
you can adjust this any way you want. you can say. if we have 258 people, we can make 32'1/4 teams of 8 people. and so on...
Part B.
32'1/4(teams)×8(people per team)=258 people
Part C.
you can explain this from what I said in Part A and Part B.
but 32'1/4 is 1/8 of 258
The approximate percentage of daily phone calls numbering between 37 and 47 is of:
68%.
<h3>What is defined by the Empirical Rule?</h3>
These approximate percentages are defined by the Empirical Rule, for a normally distributed variable:
- 68% of the measures within one standard deviation of the mean.
- 95% of the measures within two standard deviation of the mean.
- 99.7% of the measures within three standard deviation of the mean.
The mean and the standard deviation in this problem are given as follows:
- Mean: 42 calls answered each day.
- Standard deviation: 5 calls answered each day.
Hence the percentage is of 68%, as these measures are within one standard deviation of the mean.
