Answer:
$ 530.5
Step-by-step explanation:
Income = $415 + Commission
Sonia made sales of $2,200. This means she will earn 5.25% of 2,200 as commission.
5.25% of 2200= 0.0525 x 2200 = 5.25 x 22 = $ 115.5
Therefore, total income of Sonia would be:
Total income = $ 415+ $ 115.5 = $ 530.5
3a + 5b + 6a + 4b
Add up all the a's: (3a + 6a) + 5b + 4b
9a + 5b + 4b
Add up all the b's: 9a + (5b + 4b)
9a + 9b
If you want to, you can factor it: 9 (a + b)
So the fisrt thing we need to calculate is that 9 times out of 10 is 90% which will be the confidence interval.
<span>Margin of error is 6% = .06 </span>
<span>Confidence interval is 80 +/- .06 = .74 to .86. or 74% to 86$ </span>
<span>In 9 times out of 10 the confidence interval for similar samples of seniors will contain the </span><span>true mean of the population of senior scores. </span>
Answer:
x = 4
Step-by-step explanation:
Consecutive angles in a parallelogram are supplementary, sum to 180°, so
14x + 6 + 118 = 180
14x + 124 = 180 ( subtract 124 from both sides )
14x = 56 ( divide both sides by 14 )
x = 4
