Answer:
72 runners
Step-by-step explanation:
Total runners = 360
20% of the total runners are in the 35-39 age bracket.
<em>We need to find number of runner in this age bracket.</em>
<em>Which tells us that this number is simply 20% of the total, or 20% of 360.</em>

How to find percentage of number?
We convert percentage to decimal and then multiply it with the other number.
Converting percentage to decimal requires us to divide by 100. So:
20% = 20/100 = 0.2
Now,
0.2 * 360 = 72
Hence,
72 runners are in the 35-39 age bracket

We are given a parallelogram with sides:
3 1/8 and 2 3/16.
Let us convert each into improper fraction.
3 1/8 = 25/8
2 3/16 = 35/16
Now perimeter of parallelogram is given by:
Now we have to find lcd of 8 and 16.
lcd of 8 and 16 is 16.
Perimeter = 85/8 km
Answer : Perimeter of parallelogram is given by 85/8 km.
Answer:
The statement provided is TRUE.
Step-by-step explanation:
The four principle assumptions of the simple linear regression model are,
- The linearity of the relationship between the dependent variable and the independent variable. That is, value of <em>y, </em>the dependent variable for each value of <em>x</em> the independent variable is, .
- Normality of the error distribution. That is, . Thus, the variance of random error e is .
- Statistical independence of the errors or specifically no correlation between consecutive errors. That is, if , it implies that.
- Homoscedasticity of the errors, i.e. constant variance.
The first assumption clearly indicates that the <em>y</em>-values are statistically dependent upon the <em>x</em>-values.
Thus, the statement provided is TRUE.
