Answer: $69811
Step-by-step explanation:
Given : A survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years, but with a smaller percentage of participants.
One of these surveys estimates with 90% confidence that the mean household income in the U.S. falls between $69,702 and $69,920. (1)
We know that the confidence interval is given by :-
Point estimate of mean ± Margin of error
From (1) , we have
Point estimate for mean -Margin of error = $69,702 (2)
Point estimate for mean +Margin of error = $69,920 (3)
Add (2) and (3), we get
2 (Point estimate for mean) = $139622
Divide both sides by 2, we get
Point estimate for mean=$ 69811
Therefore , the point estimate for mean U.S. household income. = $ 69811
The point estimate for mean U.S. household income is $69,811.
The given information states that a survey organization, as part of the United States Census Bureau, conducts a yearly census similar to the one taken every ten years. This survey estimates with 90% confidence that the mean household income in the U.S. falls between $69,702 and $69,920. To find the point estimate for mean U.S. household income, we can simply take the average of the lower and upper bounds of the confidence interval:
Point estimate = (lower bound + upper bound) / 2
Substituting the given values, we get:
Point estimate = ($69,702 + $69,920) / 2 = $69,811

$2,000 plus a $200 bonus for each car he or she sells. At B, each salesperson is paid a fixed monthly amount of $2,500 but
does not receive a bonus for each car he or she sells. In which setting will a member of the sales staff be more likely to
work harder? Why is this important?
They would work harder at A because if they sell 3 cars they would get paid more than if they worked at B
Answer:
345
Step-by-step explanation:
To find out how many cakes the bakery can make, you'll need to convert the amount of milk they have into cups and then divide by the amount of milk needed to make one cake.
First, let's convert the 72 half-gallons of milk into cups:
1 half-gallon = 8 cups (since 1 cup is 1/8 of a half-gallon)
So, 72 half-gallons = 72 x 8 cups = 576 cups of milk.
Now, you mentioned that it takes 1 2/3 cups of milk to make a cake.
Let's convert this mixed number into an improper fraction: 1 2/3 = (3 x 1 + 2)/3 = 5/3 cups of milk for one cake.
Now, we can find out how many cakes the bakery can make by dividing the total cups of milk by the amount needed for one cake: 576 cups of milk ÷ (5/3) cups per cake = 576 cups ÷ (5/3) ≈ 345.6 cakes.
Since you can't make a fraction of a cake, the bakery can make approximately 345 cakes with the milk they have.
