2. a) $18, b) $27, c) $36
3. a) $1.64, b) $2.46, c) $3.28

7. a) $14.85, b) $24.75, c) $39.60
Explanations:
Whatever we multiply the item by, we multiply the cost by. If we double the number of socks, we double the price. If we triple the number of socks, we triple the price.
1. a) 3 costs $12, and 3 x 2 = 6, so we do the same to the price: $12 x 2 = $24
b) 3 times 3 is 9, so 3 x 12 gives you that cost, $36
c) 3 x 4 = 12, so 12 x 4 = $48
2. a) 3 pairs is $9, and we need 6 pairs. 3 x 2 = 6, so we also multiply the price x 2 = $18
b) 3 x 3 = 9 pairs, multiply the cost times 3 as well. 9 x 3 = $27
c) 3 x 4 = 12, multiply the cost x 4. 9 x 4 = 36
3. 4 apples cost $0.82
a) 4 x 2 = 8 apples, $0.82 x 2 = $1.64
b) 4 x 3 = 12 apples, $0.82 x 3 = $2.46
c) 4 x 4 = 16 apples, $0.82 x 4 = $3.28

Diego has 3 times as many, so you would multiply the amount Han had by 3.
Han has 6, so Diego has 6 x 3 = 18 comic books
A. 18 comic books.
To find the number Han has using what Diego has you would divide Diego’s number by 3:
27/3 = 9
Han has 9 comic books
B. 9 comic books
A screening test for a disease shows a positive result in 91% of all cases when the disease is actually present and in 7% of all cases when it is not. Assume that the prevalence of the disease is 1 in 650. If the test is administered to a randomly chosen individual, what is the probability that the result is positive
Answer:
0.0713 = 7.13% probability that the result is positive.
Step-by-step explanation:
Probability of a positive test:
91% of 1/650(has the disease).
7% of 1 - 1/650 = 649/650(does not have the disease). So
[tex]p = 0.91\frac{1}{650} + 0.07\frac{649}{650} = \frac{0.91 + 0.07*649}{650} = 0.0713[/tex]
0.0713 = 7.13% probability that the result is positive.

The sampling distribution describes the a. long-run behavior of a statistic. b. short-term behavior of the population. c. sample size. d. population proportion.
Answer:
Option A
Step-by-step explanation:
A probability distribution of a statistic that represents a large sample derived from a certain specific population size to determine a range of possible outcomes of statistics such as Mean, Standard deviation, mode, median etc. in a way that it represents the existing entire population is known as a sampling distribution
Hence, option A is correct

Find the median and mean of the data set below:
5, 7, 3, 36, 7, 23
Ed
Answer: mean is 13.5 and median is 7
Step-by-step explanation:
to get median you do (7+7)/2 and get 7 and for the mean you just add all of the numbers and divide by how many numbers there are. Basically it is 81/6 to get 13.5
Answer:
Median = 7
Mean = 13.5
Step-by-step explanation:
To find the median, put them in increasing order:
3, 5, 7, 7, 23, 36
cross out the values on the ends until you meet in the middle:
/, 5, 7, 7, 23, /
/, /, 7, 7, /, /
Find the average of the two middle numbers: (7+7)/2 = 7
Median = 7
For the mean, add all numbers and divide by the amount of numbers you have:
3 + 5 + 7 + 7 + 23 + 36 / 6
=81/6
= 13.5

Answer:
C. ΔABE≅ΔDBC by SAS
Step-by-step explanation:
Only two sides are marked as congruent. So, any claim using SSS is automatically false. (SSS requires 3 corresponding sides be congruent.)
Of the claims citing SAS, the one regarding ΔABD is false. The points A, B, and D are on the same line, so do not form a triangle.
The only correct claim is that of C: ΔABE≅ΔDBC by SAS
The track team has 12 more boys than girls. There are a total of 142 team members. How many boys and girls are on the team?
Answer:
77 boys, 65 girls
Step-by-step explanation:
x as the variable to represent amount of girls, and there are 12 more boys than girls (x+12). So the equation would be:
x + x + 12 = 142
2x + 12 = 142
x = 65
65 girls
then 65+ 12 = 77 boys

Write an equation to represent the following description. The difference of seven times a number and 15 is 41.
Answer: 3
7x + 15 = 41 or 7x - 15 = 41
Answer:
7x - 15 = 41
Step-by-step explanation:
The key word is "difference" so keep that in mind. 7 times a number and 15 is 41. The "number" is unknown so a variable can be put in place until the number is known. The whole equation equals 41. The word "and" is where the "difference" or subtraction sign should go. Now we have a translated description! I hope this helps and if I'm wrong, please let me know!

Answer:
D. 7°C
Step-by-step explanation:
The difference between two numbers is the distance between them on the number line.
4 -(-3) = 4 +3 = 7
Temperatures -3°C and +4°C are 7°C apart. The difference between the temperatures is 7°C.
_____
Additional comment
Often, in math, when we talk about the difference between A and B, we mean specifically the value (A-B). In plain English, when we talk about the difference between A and B, we mean the positive difference--the value obtained by subtracting the smaller number from the larger one.
Here, the difference between New York and London temperatures would ordinarily be interpreted in math to be -3 -4 = -7°C. That is not an answer choice, so we must assume the positive difference, 7°C, is intended.

Assume the total cost of a college education will be $200,000 when your child enters college in 16 years. You presently have $55,000 to invest. What annual rate of interest must you earn on your investment to cover the cost of your child’s college education?
Answer:
8.4%
Step-by-step explanation:
let x = interest rate
55,000(1 + x)^16 = 200,000
divide both sides by 55,000
(1 + x)^16 = 3.636
find the invese of 16
1 + x = 1.084
x = 0.084
x = 8.4
