1). Use the same ratio as 16 people in 25 square feet to estimate the size of a
crowd that is 10 feet deep on both sides of the street standing along a 1-mile
section of a parade route.
Answer:
33,792 people
Step-by-step explanation:
The parade route is rectangular in nature. The area of the parade route will be expressed as:
Area = Length × Breadth
If the route is 10feet deep, the length of the route = 10feet
Is the section of the route is 1 mile, the width of the parade route = 1mile × 5280ft = 5280ft
Area of the parade route = 10×5280 = 52,800ft²
If 16 people in 25 square feet is used to estimate the size of a crowd, the number of a crowd in a 52800ft² parade route is expressed as;
25ft² = 16
52800ft² = x
Cross multiply
25×x = 16×52800
25x = 844,800
x = 844,800/25
x = 33,792
Hence there are 33,792 people on 1-mile section of a parade route that is 10ft deep.

Complete the graduated commission problem: You earn 20%
commission on the first $500 of sales, 25% commission on the next
$1000 of sales, and 30% commission on all sales over $1500. If you sold
$1940, what is your total commission?
Answer: I'll give you both the percentage and dollar amount. 75% = $144
Step-by-step explanation: first, I added up all the percentages to total 75%. then I took the total sales, and divided that by .75 (75% in decimal form), so:
1940 x .75 = 1455
1940 - 1455 = 144
Write this ratio as a fraction in lowest terms

7/8 + (-3/4) + (-7/-8)+ 3/4
Answer:
1.75 or 1 3/4
Step-by-step explanation:
7/8 + (-3/4) + (-7/ -8)+ 3/4
Simplify
7/8 -3/4 -7/-8 +3/4
We can get rid of -3/4 + 3/4, because together they = 0.
7/8 - 7/-8
So then we divide and subtract and get
1.75 or 1 3/4

1. Original numbers are rounded to the nearest hundred and to the nearest thousand. The
original numbers are different from all the rounded numbers in the table.

Thousand
14,000
2,400
2,000
Answer:
Your answer would be 14,000
Answer:13,555
Step-by-step explanation: because in order for it to be rounded to the nearest 100 of 600 it would have to be over 550. If it was 550 or lower it would be rounded to 500. And in order for it to be rounded to the nearest thousand of 14,000 it would have to be a higher number than 13,550.

Which of these distributions is most likely to show data collected while studying the number of the plates people use while eating at an all you can eat buffet explain your reasoning
Answer: The second distribution.
Step-by-step explanation:
We should to expect to see a large density for the lowest number of plates (because is more common to eat 1, 2 or 3 plates than more)
For example, in the first distribution, we can see a normal distribution with a mean of 6.
This does not really make sense, because 6 plates is really a lot.
The third distribution has two peaks, one at 1 plate that has a lot of sense, and another at 10 plates, so this also does not have really a lot of sense (again, 10 plates is really a lot)
The fourth distribution seems to be even for all the number of plates, which would say that there is almost the same number of customers that eat 1 or 2 plates than the number that eats 9 or 10. This does not seem really logical, so we can assume that this is incorrect.
The second distribution is the correct one, because we see a larger density at a smaller number of plates (with a maximum at 2 plates) and the number of customers starts decreasing as the number of plates decreases (in this case, we can see that no one ordered more than 9 plates, which makes a lot of sense)

Determine what to add to make the trinomial a perfect square. x2+8x+___
Answer: 16
Step-by-step explanation:
For a perfect square each factor is identical.
Now, we have to find a number that adds to get 8.
The only option is (x+4)(x+4). When you distribute, you get x²+8x+16.
Now, we know that the missing number is 16.
