Which statement comparing the modes to the ranges is true?
Answer: A. The modes differ by 40 and the ranges differ by 40.
Step-by-step explanation:
The required, modes differ by 40 and the ranges differ by 40. Option A is correct.
To compare the modes and ranges of the given data, let's first find the modes and ranges.
Last Summer:
140, 220, 190, 180, 190
This Summer:
150, 170, 150, 190, 180
The mode is the value that appears most frequently in a dataset, while the range is the difference between the maximum and minimum values in a dataset.
The modes are as follows:
Last summer: The mode is 190 since it appears twice, more frequently than any other value.
This summer: The mode is 150 since it appears twice, more frequently than any other value.
The ranges are as follows:
Last summer: The range is 220 - 140 = 80.
This summer: The range is 190 - 150 = 40.
Now, let's compare the modes to the ranges:
Statement: The modes differ by 40 and the ranges differ by 40. Since the modes differ by 40 and the ranges differ by 40, the statement is true.
Therefore, the correct statement is:
A. The modes differ by 40 and the ranges differ by 40.

A market research survey has 15 questions and will be sent to 500 people. What is the total cost to conduct the survey if it has a $1,000 base fee plus $5 per question and $2 per person surveyed?
Answer:
Total cost to conduct survey = $2075
Step-by-step explanation:
Given that:
Number of questions on survey = 15
Number of people = 500
Base fee = $1000
Per question charge = $5
Per person surveyed = $2
Let,
q be the number of questions
p be the number of people
Total cost = Base fee + 5q + 2p
Total cost = 1000 + 5(15) + 2(500)
Total cost = 1000 + 75 + 1000
Total cost = $2075
Hence,
Total cost to conduct survey = $2075
A rectangular field is 10m longer than wide. The area of the field is 2000m². Find the perimeter of the field.
Answer:
180m
Step-by-step explanation:
Let L = length of field,
W = width of field,
A = field area = 2000 m^2
Lenght = Width + 10m
Let Lenght= x
Width=y
A = X ×Y = (Y + 10)Y= 2000
Y^2 + 10Y- 2000 = 0
Solving using Quadratic eqn with plot
Y= 40 or -50 but we go for the positive root
Width=40m
Length= 40m +10m
= 50m
Perimeter= 2(l+w)
=2(50+40)
180m
Hence, the perimeter is 180 m

The required cost of the item after 4% of sales tax is given as $78.
What is the percentage?The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
Here,
Let the total cost of the item be x,
According to the question,
x = cost + sales tax
X = 75 + 4% of 75
x = 75 + 3
x = $78
Thus, the required cost of the item after 4% of sales tax is given as $78.

6 boy students make up 24% of the total class how many total students are in class
Answer:
There are 25 students in the class.
Step-by-step explanation:
1. Set up an equation. The equation would be 6 = 24/100x.
2. Solve the equation. You can solve this by multiplying both sides by 100/24, and 100/24 * 6 = 25. You would then get that x = 25, which means that the number is 25.

If the probability that the Islanders will beat the Rangers in a game is 5/6, what is the probability that the Islanders will win exactly five out of seven games in a series against the Rangers?
Answer:
0.234
Step-by-step explanation:
Given that:
Proportion, (p) ; Islanders beat rangers = 5/6 = 0.8333
Probability that islander win exactly 5 out of 7 games
1 - p = 0.1667
Usingbthe binomial distribution formula :
P(x =x) = nCx * p^n * (1 - p)^(n - r)
P(x = 5) = 7C5 * 0.833^5 * 0.1667^2
P(x = 5) = 21 * 0.833^5 * 0.1667^2
P(x = 5) = 0.23405369484362783281917
P(x = 5) = 0.234

Mr. Selan loves the 99-cent menu at Wendy's (sadly prices went up a few years ago). He used to buy two chicken sandwich at 99-cents each. With a tax of 8.5%, how much would he pay for the two sandwiches? Round your answer to the nearest cent
Answer:
Mr. Selan would pay $2.15 for the sandwiches with tax.
Step-by-step explanation:
Given that:
Cost of each sandwich = 99 cents
Cost of two sandwiches = 99*2 = 198 cents
Sales tax = 8.5%
Sales tax = [tex]\frac{8.5}{100}*198=16.8\ cents[/tex]
Sales tax = 17 cents
Total cost = 198 + 17 = 215 cents
Total cost = $2.15
Hence,
Mr. Selan would pay $2.15 for the sandwiches with tax.

Answer:
$88
Step-by-step explanation:
first, you find 20% of 57 which = 11.4
then subract it with 57 which looks like 57-11.4 = 45.6
= 45.6
first, you find 20% of 53 which = 10.6
then subract it with 53 which looks like 53-10.6 = 42.7
= 42.4
then you add them both which = 45.6+ 42.4= 88
