con you be more organized on how you post the question will answer if fixed
Step-by-step explanation:
A trade magazine routinely checks the drive-through service times of fast-food restaurants. Upper AA 9595% confidence interval that results from examining 773773 customers in one fast-food chain's drive-through has a lower bound of 169.0169.0 seconds and an upper bound of 172.2172.2 seconds. What does this mean?
Answer:
One can be 95% confident that the drive-through service times of fast-food chain is between 169 seconds and 172 seconds.
Step-by-step explanation:
The confidence interval gives a range of value for the population mean or parameter, which is calculated from the statistic value of the data (that is sample statistic). This range gives the interval which is associated with a certain level of confidence for which the interval will contain the true value of the unknown parameter (true value). In the scenario above, the associated confidence level is 95%.Hence, we can be 95% confident that the true value will be continued with the interval (169 ; 172)
How do you find the perimeter on s polygon?PLS HELP ME on this question
Answer:
To find the perimeter of a polygon, you just have to add the values of each side.
For example, if a rectangle has a length of 10 inches and a width of 5 inches, you would add, 10 + 10 + 5 + 5, which is equal to 30. This is found because the length of one side is 10, the other is also 10, and the width is 5, and the other is also 5.

A trapezoid with base measures of 23 km and 29 km has an area of 390
km2 find the height of the trapezoid.
Answer:
height (h) = 15
Step-by-step explanation:
To figure this out, we use the formula 2 · [tex]\frac{A}{a + b}[/tex], where "A" is the area, "a" is one base measure, and "b" is the other base measure.
After plugging in the numbers into the formula, we get 2 · [tex]\frac{390}{23 + 29}[/tex], which equals 15.

Isaac’s dad built a shelf for his video games that is 42 inches wide.Each video game is 6/8 inches wide.How many video games can Isaac fit on the shelf ?
Answer: 56
Step-by-step explanation:
Since we are informed that Isaac’s dad built a shelf for his video games that is 42 inches wide and that each video game is 6/8 inches wide.
The number of video games that Isaac can fit on the shelf will be gotten by dividing the length of the shelf by the width of each video game. This will be:
= 42 ÷ 6/8
= 42 × 8/6
= 56
Therefore, Isaac can fit 56 video games on the shelf.

yo i need help wit 17 and 18 i’ll give u a brainliest you please
Answer:
17. See below
18. 750
Step-by-step explanation:
17. Since the lollipops are being sold at the same price, 50 cents, for each one sold, they make a constant amount of money. For each increase in lollipops sold, there is a constant increase in money made, and thus the situation is a linear function.
18. To solve this equation, let's say y is the money made at the convention in dollars and x is the number of lollipops sold. If the principal gave them 125 dollars before they sold any lollipops (0 lollipops sold), then 125 is the y-intercept of the function, and in the equation y=mx+b, b=125. If each lollipop costs 50 cents (half of a dollar), then for each lollipop, x, sold, .5 dollars are made and are added to the profit, y. Thus, .5 dollars is the slope. The equation then becomes:
[tex]y=0.5x+125[/tex]
Now, if they need 500 dollars, y is thus equal to 500 dollars. Solving the equation:
[tex]500=0.5x+125[/tex]
[tex]500-125=0.5x[/tex]
[tex]375=0.5x[/tex]
[tex]\frac{375}{0.5} =x[/tex]
[tex]375*2=x[/tex]
[tex]750=x[/tex]
Thus, 750 lollipops must be sold.

This is what it is.
Answer: 358,002,479
Step-by-step explanation:
First, you have 358 million, or 358,000,000.
Next, you have 2,000. You can add that to 358,000,000 and you get 358,002,000.
Finally, you have 479. You can add that to 358,002,000, and get 358,002,479.
Here's a visual representation:
358,000,000
