9 times 8 equals 72
72 plus 2 equals 74
74 minus 1 equals 73
your answer would be 73
Answer:
The correct option is D i.e. Quantitative because numerical values found by either measuring or counting are used to describe the data.
Step-by-step explanation:
As the number of respondents is a numerical value and is identified by counting thus it is a quantitative variable. Also all the other options are incorrect.
A is incorrect because the reason described is not the property of quantitative data.
B is incorrect because the data is not described in descriptive terms.
C is incorrect because the reason described in not a property of qualitative data.
Answer:
B - 9
Step-by-step explanation:
5 x 9 = 45 or 45 divided 5
Answer: For the sum of 130
First: $90
Second: $40
Step-by-step explanation:
We write equations for each part of this situation.
<u>The Total Charge</u>
Together they charged 1550. This means 1550 is made up of the first mechanics rate for 15 hours and the second's rate for 5 hours. Lets call the first's rate a, so he charges 15a. The second's let's call b. He charges 5b. We add them together 15a+5b=1550.
<u>The Sum of the Rates</u>
Since the first's rate is a and the second is b, we can write a+b=130 since their sum is 130.
We solve for a and b by substituting one equation into another. Solve for the variable. Then substitute the value into the equation to find the other variable.
For a+b=130, rearrange to b=130-a and substitute into 15a+5b=1550.
15a + 5 (130-a)=1550
15a+650-5a=1550
10a+650-650=1550-650
10a=900
a=$90 was charged by the first mechanic.
We substitute to find the second mechanic's rate.
90+b=130
90-90+b=130-90
b= $40 was charged by the second mechanic
