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 number m and 58 are additive inverses.
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.
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.
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
The complete question is:

3/8 c−2= 3/2 c−12 helpp
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

A triangle in the coordinate plane has coordinates of (2,3), (-4,-5), and (-2, 4). It is translated 3 units down. What are its new coordinates?
A (5,3), (-1,-5), (1,4)
B (2,6), (-4,-2), (-2, 7)
C (2,0), (-4,-8), (-2, 1)
D (-1,3), (-7,-5), (-5,4)
I need this done fast
translated 3 units down means the x stays the same and you subtract 3 from the Y
so (2,3) becomes (2,0)
(-4,-5) = (-4,-8)
and (-2,4) = (-2,1)
so new coordinates are C. (2,0), (-4,-8), (-2,1)

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
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.
