In a class of 160 students, 90 are taking math, 78 are taking science, and 62 are taking both math and science. What is the probability of randomly choosing a student who is taking only math

Answers

Answer 1

The probability of choosing a student who is taking only math from a class of 160 students, with 90 taking math and 62 taking both math and science, is 0.175.

The question asks for the probability of randomly choosing a student who is taking only math in a class of 160 students, where 90 are taking math, 78 are taking science, and 62 are taking both math and science. To find the number of students taking only math, subtract the number of students taking both subjects from the total number taking math (90 - 62 = 28). The probability is then the number of students taking only math divided by the total number of students, which is 28/160.

The probability can be calculated as 28 divided by 160, or 0.175.

The table shows Katrina's prices for dog walking. If she walks 5 medium-sized dogs and 8 large-sized dogs for 12 weeks, how much will she earn?

Table:
•Small Dog = $10 Per Week
•Medium Dog = $12 Per Week
•Large Dog = $14 Per Week

Answers

5x$12= 60$ so 60$per week 60$x12 = $720 for the Medium dogs.

8x14$= 112$ per week, she walked them 12 weeks. 112x12= $1344 for the large dogs.

Now take the two prices $720+$1344= $2,064 

She earned a total of $2,064 from walking the dogs.

What is 40% of 25? Use an appropriate technique to solve. A. 10 B. 62.5 C. 100 D. 1000

Answers

The correct answer is A.10.
The answer for this is A. 10
In this type of question, you need to transfrom the amount of percentage into fractions first and multiply it as usual.

40%  =   40/100    = 4/10 

So, 40% of 25 is:

4/10 x 25

= 100 / 10

= 10

Please show all work, and this on solving equations with integers, Thank you:)

Answers

the answer would be 15 because
v could be any number so you just divide 195 by -13 and you will get 15 just make it negative because negative x negative = positive
You divide -13 from both sides. So V=-15

Drag and drop 58 and m to their correct positions on the number line.

Drag and drop the label “Sum” to the sum of 58 and m.

Answers

it's zero, additive inverse means they're opposite numbera

Answer:

[tex]m=-\frac{5}{8}[/tex]

Step-by-step explanation:

We have been given that the number m and 58 are additive inverses.

We know that two numbers are additive inverses when they add up-to 0.

[tex]\frac{5}{8}+m=0[/tex]

[tex]\frac{5}{8}-\frac{5}{8}+m=0-\frac{5}{8}[/tex]

[tex]m=-\frac{5}{8}[/tex]

Therefore, the additive inverse of [tex]\frac{5}{8}[/tex] would be [tex]-\frac{5}{8}[/tex].

at a yard sale you find 5 paperback books by your favorite author. each book is $0.75. write a rule for the amount (in dollars) you spend as a function of the number of books you buy.

Answers

y = 0.75x....where y is the total cost and x is the number of books

or it could be f(x) = 0.75x...in function notation

The function for the amount of money left after buying books is y = 10 - 0.75x.

Let x represent the number of books you buy. Each book costs $0.75, so the total cost for x books is 0.75x. You start with $10.

Therefore, the amount of money you have left, y, can be represented by the function:

y = 10 - 0.75x

For example, if you buy 3 books, the remaining money would be:

y = 10 - 0.75(3)

= 10 - 2.25

= 7.75

​3/8 c−2= ​3/2 c−12 helpp

Answers

Final answer:

The solution involves clearing the equation of fractions, rearranging terms to isolate the variable c, and then solving for c by dividing both sides by 9 to obtain c = 80/9.

Explanation:

The student is asking for help solving a linear equation. To assist with this mathematics problem, it's crucial to use algebraic methods to isolate the variable c. Here is the step-by-step solution:

Given:

​3/8 c − 2 = ​3/2 c − 12

First, let's clear the fractions by multiplying every term by 8 to get rid of the denominators:

8(​3/8 c) − 8(2) = 8(​3/2 c) − 8(12)

Which simplifies to:

3c − 16 = 12c − 96

Next, subtract 3c from both sides to move all terms with c to one side:

− 16 = 9c − 96

Now, add 96 to both sides to isolate the c term:

80 = 9c

Finally, divide both sides by 9 to get the value of c:

c = 80 / 9

Rohan did a survey in four bird parks and wrote the following observations:


Bird Park Survey
Park Number of Yellow Birds Total Number of Birds
P 33 53
Q 20 48
R 54 90
S 44 83


Based on the survey, which park had the greatest percentage of yellow birds?
Park P
Park Q
Park R
Park S

Answers

Answer:  Park P

Step-by-step explanation:

Since, According to the question,

Number of yellow bird in park P = 33

Total number of the bird in park P = 53

Thus, the percentage of yellow bird in park P = [tex]\frac{33}{53} \times 100[/tex]= 62.264150943% ≈ 62 %

Number of yellow bird in park Q = 20

Total number of the bird in park Q = 48

Thus, the percentage of yellow bird in park P = [tex]\frac{20}{48} \times 100[/tex]=41.666666666% ≈ 42%

Number of yellow bird in park R = 54

Total number of the bird in park R = 90

Thus, the percentage of yellow bird in park R = [tex]\frac{54}{90} \times 100[/tex]= 60 %

Number of yellow bird in park S = 44

Total number of the bird in park S = 83

Thus, the percentage of yellow bird in park P = [tex]\frac{44}{83} \times 100[/tex]=53.012048192 % ≈ 53 %

Since, 62% > 60% > 53% > 42%

Therefore, highest percentage of the yellow bird is 62 %

Which is present in park P.
