Answer:
Step-by-step explanation:
<u>Measure B and C:</u>
<u>Subtract 110° - 40°:</u>
- 110° - 40°
- = 110 - 0
- = 110 - 40
- = 70°
<u>The measure of ∠BFC is 70°.</u>
Answer:
$8.75
Step-by-step explanation:
It is given that,
Roger sells 23 necklaces at a fair a total of $ 201.25.
We need to find the price of 1 necklace. We can use unitary method to find it.
23 necklaces = $201.25.
For cost of 1 necklace, divide $201.25 by 23 as follows :
So, the cost of 1 necklace is $8.75.
Answer:
(0.1753 ; 0.2447)
Step-by-step explanation:
Using the relation :
Confidence interval :
p ± margin of error
p = 0.21
1 - p = 0.79
n = 530
Zcritical at 95% confidence level = 1.96
Margin of Error : Zcritical * sqrt[(p(1-p))/n]
1.96 * sqrt[(0.21(0.79))/530]
1.96 * 0.0176923 = 0.0346769
Margin of Error = 0.0346769
Lower boundary = 0.21 - 0.0347 = 0.1753
Upper boundary = 0.21 + 0.0347 = 0.2447
Confidence interval :
(0.1753 ; 0.2447)
Answer:
$80.99
Step-by-step explanation:
Turn the percentage into a decimal.
19% -> 0.19
Multiply.
99.99 * 0.19 ≈ 19
Subtract.
99.99 - 19 = 80.99
Best of Luck!
