Answer:
92% Confidence Interval = [8.515, 8.605]
Step-by-step explanation:
The number of samples given is 15,this less than 30, hence, we use the t score confidence Interval
= Mean ± t score × Standard deviation/√n
Mean = 8.56 ounces
Standard deviation = 0.09 ounces
n = 15
We find the degrees of freedom = n - 1
= 15 - 1 = 14
Using the T score table
T score for 92% confidence interval with degrees of freedom 14
= 1.8875
Hence:
Confidence Interval =
= 8.56 ± 1.8875 × 0.09/√15
= 8.56 ± 0.0454010035
Confidence Interval
8.56 - 0.0454010035
= 8.5145989965
≈ 8.515
8.56 + 0.0454010035
= 8.6054010035
≈ 8.605
92% Confidence Interval = [8.515, 8.605]
Answer: 1,200.65+ 985.43+ 1,200.23= 3,386.31

Answer:
x>4
Step-by-step explanation:
Use the distributive property to multiply 2 by x−3.
2x−6+5x<9x−14
Combine 2x and 5x to get 7x.
7x−6<9x−14
Subtract 9x from both sides.
7x−6−9x<−14
Combine 7x and −9x to get −2x.
−2x−6<−14
Add 6 to both sides.
−2x<−14+6
Add −14 and 6 to get −8.
−2x<−8
Divide both sides by −2. Since −2 is <0, the inequality direction is changed.
x>-8/-2
Divide −8 by −2 to get 4.
x>4

Answer:
7 pieces
Step-by-step explanation:
change 4 5/6 into an irregular fraction. 29/6
divide 29/6 by 2/3. to do this, flip and multiply
29/6 * 3/2 = 87/12 = 7.25 or 7 whole pieces
