Answer: 6/7
The mean is calculated by adding all the data values together, and then dividing the sum by the number of data values.
12+10+11+13+14+10+12+13+14=109
109÷9≈12.1
<u>The mean of the data set is about 12.1.</u>
Answer:
D
Step-by-step explanation:
If we use the calculator will find out that x= √151/2 ≈ 6.1441
D. 6 < x < 7
x is less then 7 and greater than 6
Without the calculator you can think that 151 is almost 144 that is 12² so
we can approximate √151 to be a bit more then 12
√151/2 = a bit more then 12 /2 = 6 and a bit more
Your business partner is correct; there is a positive correlation. As fat goes up, the calorie count tends to increase with it
Answer:
- Senators: 90
- Representatives: 430
Step-by-step explanation:
Let s represent the number of Senators in the Congress. Then the number of Representatives is (5s-20) and the total number of members is ...
s + (5s -20) = 520
6s = 540 . . . . . . . . . add 20, simplify
s = 90 . . . . . . . . . . . divide by 6
The number of Senators is 90; the number of Representatives is 430.
_____
You can find the number of Representatives either as 520 -90 = 430 or as 5·90 -20 = 430.
