Ask all the students from a randomly chosen class of 25 students to choose their favorite vegetables.

Ask 100 randomly chosen students from the student population to choose their favorite vegetables.

Ask the parents of 100 randomly chosen students to choose their favorite vegetables.

Ask 25 students who have purchased vegetables during lunch to choose their favorite vegetables.

Answers

Answer 1

the answer is b.

a is biased because it is only one class answering.

c is wrong because the school is supposed to survey children.

d is biased because children who normally purchase vegetables are more likely to like ones that other students don’t like.

Kim deposited $1,422 into a savings account. After 5 years, she had a total of $1,635.30 in her account. What is the interest rate?

Answers

Answer:

42.66%

Step-by-step explanation:

subtract the amount of money from after and before: 1,635.30 - 1,422 = 213.3

divide the amount of money gained by the years: 213.3/5 = 42.66

The person above is correct because if you take the original amount Kim had and subtract that from the amount currently there you get 213.30 and you take that and divide that by 5 because of the 5 years you get
42.66%

Answer:

d = -10/7 = -1 3/7

that is the answer for number 1.

For number 2. the answer is U = 13/4 = 3 1/4 = 3.25

step by step explanation

multiply both sides of the equation by 4 the least common multiple of 2,4

2 (5 x 2 + 1) -4 u = 9 then multiply 5 and 2 to get 10

2 (10 + 1) -4u =9

then add 10 and one to get 11

2 x 11 -4u =9

then multiply two and 11 to get 22

22 -4u = 9

then subtract 22 from both sides

subtract 22 - 9 to get -13

-4u = -13 then undo multiplication by dividing both sides divide both sides by 4-13 / -4 can be divided by positive 13/4

your answer is 13/4

then, C is 5

50+10=60

50-10=40

Answer:

Step-by-step explanation:

A+B=60

A=60-B

substitute the value of A in

A-B=40

60-B-B=40

60-40=2B

20/2=B

10=B

Now, substitute the value of B in

A+B=60

A+10=60

A=60-10

A=50

There are a few reasons thay Tammy's
sample may not be valid. Firstly, she had a

she had a potentially large margin of error.
Additionally, she was asking students from

created a bias simply due to the fact that

What is the total amount of Luis' pies that were left over?

Answers

Answer:

2 1/4 pies

Step-by-step explanation:

Find out how much pie was leftover from each pie:

Apple pie: 3/4, 4 - 3 = 1, 1/4

Blackberry: 1/2, 2 - 1 = 1, 1/2

Blueberry: 1/8, 8 - 1 = 7, 7/8

Cherry: 5/8, 8 - 5 = 3, 3/8

Peach: 3/4, 4 - 3 = 1, 1/4

There are 1/4, 1/2, 7/8, 3/8, and 1/4 pies left. The LCD if these numbers is 8, since 2*4 = 8, 4*2 = 8, and 8*1 = 8

1/4 = 2/8

1/2 = 4/8

7/8 = 7/8

3/8 = 3/8

1/4 = 2/8

2 + 4 + 7 + 3 + 2 = 18, so 18/8 pies, or 2 2/8, or 2 1/4

The two dot plots below show the heights of some sixth graders and some seventh graders:

Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot for the first mark, there are 3 dots above the second mark, 2 dots above the third mark.

Lisa went on a 52km hike. She divided the distance traveled evenly over 4 days.

How many meters did Lisa walk each day?

Answers

Answer:

52km divided by 4 = 13000m

Step-by-step explanation:

52 kilometers divided by 4 days is 13000 meters

4 days hike = 52km
1 day hike = 52/4
= 13km

1 km = 1,000m
13km = (13 x 1,000)
= 13,000m

Therefore Lisa walked 13,000 metres each day on her 4 day hike.

What part of 1hr and 40 min is 25 min as a fraction?

Answers

Step-by-step explanation:

1 hour = 60 minutes

40 minutes out of an hour can be written as: 40/60

Fraction = 40/60

= (2 × 30) / (3 × 20)

Canceling out common factors of numerator and denominator, we get 2/3

Therefore, 40 minutes is 2/3 of an hour.

40 minutes is 2/3 of an hour
