ms. reynolds, the math teacher, was disappointed to announce that only 22% of her 68 students passed an exam. How many students failed the test?

Answers

Answer 1
Answer: either a student passes an exam or fails it. that means the percentage of students who pass plus the percentage of students who fail must add to 100%. this also means that if 22% pass, then 78% fail. there are 68 students total and 78% fail so the number of students failing is:
(78/100)(68) = 53.04 which is approximately 53 students.

let me know if you have any questions!!!!

The ratio of adults to children at a picnic is 4 to 5. The total number of people at the picnic is 27. How many adults and children are at the picnic? Include steps.

Answers

There are 12 children and 15 adults at the picnic.

Add together the ratios 4 and 5 and divide the amount of people by that number (so 27 divided by 9)

You then get 3. So then multiply both sides of your ratio by 3. (4:5 ----> 12:15)

Hope this helps a little.

Josie has a 1364 page book to read over summer vacation she wants to read the same number of pages each day for 62 days what is the total number of pages Josie will need to read each day

Answers

1364 pages/62 days = 22 pages per day

Final answer:

Josie must read 22 pages per day in order to finish her 1364 page book over a 62-day summer vacation.

Explanation:

This question is about dividing a total quantity into equal daily amounts. It requires the use of division in mathematics. To find out how much Josie needs to read each day, we need to divide the total number of pages (1364) by the total number of days (62).

The division equation is: 1364 ÷ 62 = 22.

So, Josie needs to read 22 pages each day in order to complete her book in the given time period.

What number is 74% of 58?

Answers

You have to learn how to translate some common words into
algebraic expressions and equations.

Here are a few:

"is" means "equals".
When you see "is", write an 'equals sign.  (  =  ).

"percent" or the symbol " % " means "divided by 100".
When you see (a number) with 'percent' or ' % ' after it,
write (the number) 'divided by 100'.

"of" means "times".
When you see "of", write 'times' or whatever symbol you like to use for it.

A fraction-bar ( / ) and 'divided by' mean the same thing.
When you see either one, you can always write the other one if you want to.
Examples:
                  ' 1 divided by 2 ' means  1/2 .

                 47/54 means ' 47 divided by 54 '.

Now we're ready to look at the example in your question:

               What number is 74% of 58 ?

Translation:    Answer =  74/100  times 58

Look how simple that is !

Just punch that into your calculator, or work it out with a pencil,
and you've got it.

                        Answer = (74 x 58) divided by 100 = 42.92


74%=0.74

0.74 x 58= 42.92

Given the data, as shown in the image below, determine if the distribution is uniformly distributed, symmetrically distributed, skewedright, or skewed left.
a. skewed left
b. skewed right
c. Symmetric d. Uniform

Answers

Answer:

Option C) Symmetric

Step-by-step explanation:

Skewed left graph is the one where, the data is much more distributed to the left.

Skewed right graph is the one where, the data is much more distributed to the right.

A uniform graph is the one where all the data in the graph is same or nearly same, for each variable on X axis.

A symmetric graph is the one where, all the data from the center is evenly distributed on both the sides, from center it looks they look like a mirror image.

In the above data, looking from the center the data is increasing on both sides uniformly, cat-rabbit and dog-mice have same values, thus is symmetric.

The distribution in the image is b) skewed right.

A skewed right distribution has a longer tail on the right side than on the left side. This means that there are more values in the distribution that are greater than the mean than there are values that are less than the mean.

In the image, we can see that the tail of the distribution on the right side is longer than the tail on the left side. This indicates that there are more values in the distribution that are greater than the mean than there are values that are less than the mean. Therefore, the distribution is skewed right.

The other answer choices are not correct.

Uniform distribution: A uniform distribution is one in which all values are equally likely. The distribution in the image is not uniform because the values on the right side of the distribution are more likely than the values on the left side of the distribution.

Symmetric distribution: A symmetric distribution is one in which the left and right sides are mirror images of each other. The distribution in the image is not symmetric because the tail on the right side is longer than the tail on the left side.

Skewed left distribution: A skewed left distribution has a longer tail on the left side than on the right side. The distribution in the image is not skewed left because the tail on the right side is longer than the tail on the left side.

Therefore, the distribution in the image is b) skewed right.

PLEASE HELP ASAP!!!Which sets of side lengths represent Pythagorean triples? Check all that apply.

Answers

Answer with Step-by-step explanation:

For the Pythagorean triples, the square of largest number must be equal to the sum of squares of remaining two numbers.

1,2,5

5²=25

1²+2²=5

25≠5

Hence, it is not a Pythagorean triple.

6,8,14

14²=196

6²+8²=100

100≠196

Hence, it is not a Pythagorean triple.

8,15,17

17²=289

8²+15²=289

Hence, it is a Pythagorean triple

10,24,26

26²=676

10²+24²=676

Hence, it is Pythagorean triple

15,20,30

30²=900

15²+20²=625

900≠625

Hence, it is not a Pythagorean triple

28,45,53

53²=2809

28²+45²=2809

Hence, it is a Pythagorean triple

8,15,17 is one, 10,24,26 is one, and 28,45,53 is one
