The amount that two groups of students spent on snacks in one day is shown in the dot plots below.
Group A
A dot plot titled Group A. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 5 above 1, 4 above 2, 1 above 3, and 0 above 4 and 5.
Group B
A dot plot titled Group B. A number line going from 0 to 5 labeled Amount in Dollars. There are 0 dots above 0, 3 above 1, 2 above 2, 4 above 3, 0 above 4, and 1 above 5.
Which statements about the measures of center are true? Select three choices.
The mean for Group A is less than the mean for Group B.
The median for Group A is less than the median for Group B.
The mode for Group A is less than the mode for Group B.
The median for Group A is 2.
The median for Group B is 3.
Answer:
1. The mean for Group A is less than the mean for Group B
2. The median for Group A is less than the median for Group B.
3. The mode for Group A is less than the mode for Group B.
Step-by-step explanation:
1. To find the mean for Group A, you use the formula: Total sum/Total frequency.
To find the total sum, you multiply the frequency(how many times the given number is repeated) with the given numbers.
0 × 0 = 0
1 × 5 = 5
2 × 4 = 8
3 × 1 = 3
4 × 0 = 0
5 × 0 = 0
Total Sum: 5 + 8 + 3 = 16
Total frequency: 5 + 4+ 1 = 10
[tex]\frac{16}{10}[/tex] = 1.6
To find the mean for Group B, you repeat everything above.
0 × 0 = 0
1 × 3 = 3
2 × 2 = 4
3 × 4 = 12
4 × 0 = 0
5 × 1 = 5
Total Sum: 3 + 4 + 12 + 5 = 24
Total frequency: 3 + 2 + 4 + 1 = 10
[tex]\frac{24}{10}[/tex] = 2.4
2. I can't explain it but I'm certain that it is correct.
3. The most repeated number for Group A is 1, it is repeated 5 times, while the most repeated number in Group B is 3, it is repeated 4 times.
Use the expression below.
-4b + 8c + 12 - 8b - 2c + 6
Part A
Simplify the expression.
Part B
Factor the simplified expression using
the GCF.
Part C
What is the value of the expression
when b = 2 and c = -3?
Answer:
Part A) − 12 b + 6 c + 18
Part B) -2b + 1c + 3
Part C) -4
Step-by-step explanation:
Part A)
Step 1:
-4b + -8b = -12b
Step 2:
8c + 2c = 6c
Step 3:
12 + 6 = 18
Answer: − 12 b + 6 c + 18
Part B)
GCF = 6
Step 1:
-12 divided by 6 = -2b
Step 2:
6 divided by 6 = 1c
Step 3:
18 divide by 6 = 3
Answer: -2b + 1c + 3
Part C)
Step 1: Subsitute 2 for b and 3 for c
(− 2 x 2 ) + (1 x -3) + 3
Step 2: Multiply (− 2 x 2 ) + (1 x -3) + 3
-4 + (-3) + 3
Step 2: Add -4 + (-3) + 3
-7 + 3 = -4
Answer: -4

A card was selected at random from a standard deck of cards. The suit of the card was recorded, and then the card was put back in the deck. The table shows the results after 40 trials.
What is the relative frequency of selecting a club?
17%
20%
25%
30%
PLEASE ANSWER QUICKLY
Answer:
25%
Step-by-step explanation:
This is the answer because there are 4 different types of cards that can be chosen, the amount of trials is insignificant in this question. Since there are 4 types, there is a 1/4 chance of picking a club, another way to put this is 25%, thus giving your answer!

If the crane operator works 30 years and the train engineer works 33 years, who makes the most lifetime income? How much more?
Crane Operater|| Annual salary : 54,830|| Years of Education: 4
Train engineer|| Annual salary : 50,610 || Years of Education: 6
Answer:
The train eingineer.
Step-by-step explanation:
So, to find the lifetime income, we must multiply the annual income by the years of work.
So for the cran operator:
54,830*30
=
1,644,900
Now lets compare this to the train eingineer:
50,610*33
=
1,670,130
So looking at the two numbers:
1,670,130(train eingineer)>1,644,900(crane operator)
So the trian eignineer makes more than the crane operator.
Now lets find the amount.
To do this, lets subtract the larger value by the smaller value:
1,670,130-1,644,900
=
25,230
So the train eingineer made 25,230 more dollars than the crane operator.
Hope this helps!
