Given:
40 people

box plot data:
minimum age : 20
Q1: 28
Median: 34
Q3: 42
maximum age: 48

Q1 represents 25% of the data set. 

40 x 25% = 10 

There are 10 people who are aged 28 and below. 

1st quartile is equal to 25% of the data set, the median is equal to 50% of the data set, 3rd quartile is equal to 75% of the data set.

Find the zeros of polynomial function.<br> f(x)=x^2-x-90
Fofino [41]

First step is to factor. With a polynomial function in the form ax² + bx + c = f(x), we have to find what factors of term C have a sum of term B.

So with this, we need factors of -90 add up to become -1. Your factors are - 10 and 9.

f(x) = x² + 9x - 10x - 90

Now we group together and pull out GCFs.

f(x) = (x² + 9x) + (10x - 90)

f(x) = x(x² + 9) - 10(x + 9)

f(x) = (x - 10)(x + 9)

Now, set each factor equal to zero.

x - 10 = 0, x + 9 = 0

For the first equation you are going to add 10 to both sides to get x by itself. Subtract 9 from both sides in the second equation for the same reason.

x = 10, x = -9

Your zeros are at x = -9, 10 or at the ordered pairs (-9, 0) and (10, 0).

Find the median of the data set: 3, 7, 3, 2, 7, 9.<br><br> A: 7 <br> B: 5<br> C: 5.3<br> D: 3
harina [27]

To find the median, you order the numbers from least to greatest, then find the middle number.

3,7,3,2,7,9

2,3,3,7,7,9

There are two middle numbers, so we have to find the middle of the two.

3,4,5,6,7

5 is the median, so the answer is B.

hope it helps

B)N times 4= P

C) 15 times 4= $60 Profit. Because each pie is 4$

D) if 144$ are made and each pie is $4, you’d divide 144 by 4= 36. 36 Pies were sold.
