Come now ! I'm sure you could unravel it if you look at it and think about it
for a minute or two.
What's an angle bisector ? It's a line that splits an angle exactly in half.
The two little angles on each side of it are EQUAL. Each of them is exactly
half of the big angle.
So in this drawing, (3/2 x - 6) is equal to (1/4 x + 4) .
Do you think you could find 'x' ?
3/2 x - 6 = 1/4 x + 4
Add 6 to each side of the equation: 3/2 x = 1/4 x + 10
Multiply each side by 4 : 6 x = x + 40
Subtract 'x' from each side: 5 x = 40
Divide each side by 5 : x = 8
Angle CBD is 1/4 x + 4 . That's 1/4 (8) + 4 = 2 + 4 = <u>6 degrees </u>
Answer:
The 95% confidence interval for the population variance is (8.80, 32.45).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for the population variance is given as follows:
It is provided that:
<em>n</em> = 20
<em>s</em> = 3.9
Confidence level = 95%
⇒ <em>α</em> = 0.05
Compute the critical values of Chi-square:
*Use a Chi-square table.
Compute the 95% confidence interval for the population variance as follows:
Thus, the 95% confidence interval for the population variance is (8.80, 32.45).
It should be noted that the hourly delivery rate is calculated by dividing the income made by the number of hours worked.
<h3>How to calculate the hourly delivery rate</h3>
Your information is incomplete. Therefore, an overview of the information will be given.
In order to get an hourly rate, it's important to divide the income that the person gets by the number of hours that the person worked.
In this case, let's say that the income is $20000 and the number of hours that was worked monthly was 240 hours, the hourly rate will be:
= $2000/240
= $8.33 per hour
