Answer:
This statement can be made with a level of confidence of 97.72%.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 8.1 mm
Standard Deviation, σ = 0.5 mm
Sample size, n = 100
We are given that the distribution of thickness is a bell shaped distribution that is a normal distribution.
Formula:
Standard error due to sampling:
P(mean thickness is less than 8.2 mm)
P(x < 8.2)
Calculation the value from standard normal z table, we have,
This statement can be made with a level of confidence of 97.72%.
Answer:
<1 <2 and <1 <4
Step-by-step explanation:
A supplementary angle is a straight line with 180 degrees.
The cups of milk Laura gave to Maria is 19/12 cups is 19/12 cups
<h3>How to calculate fraction</h3>
- Total cups of milk to share = 2 1/4 cups
Total = Laura + Maria
2 1/4 = x + 2/3
2 1/4 - 2/3 = x
9/4 - 2/3 = x
(27-8) / 12 = x
19/12 = x
= 1 7/12
Therefore, the cups of milk Laura gave to Maria is 19/12 cups

The first thing you should do is make the equation 4x+1=13 to find x. You then remove 1 from each side to get 4x=12, and then you divide by 4 to get x=3.
The next thing you do is make the equation -2y+8(3)=y+2(3)
Which simplified is -2y+24=y+6. You then add 2y to each side and remove 6 from each side to get the 18=3y. You then divide by 3 to get y=6.
