7. i would guess 95-100 people were surveyed. the way you estimate this is by adding the number of students in each category. ex. about 3 in the first bar, about 9 in the next
8. no, you could not list the exact height because the data given only shows the number of students in between 75-80, not their actual height.
Answer: C
<u>Step-by-step explanation:</u>
5(z - 4) - z = 4z - 20
<u>5z</u> - 20 <u>- z</u> = 4z - 20
4z - 20 = 4z - 20
<u>-4z </u> <u>-4z </u>
-20 = -20
TRUE
Since it is a true statement, there are infinitely many solutions

Answer: D
<u>Step-by-step explanation:</u>
Eric: 1 hot dog
Mark: 1 hot dog + 1 soda + 1 peanuts
Total: 2 hot dogs + 1 soda + 1 peanuts
= 2(3.50) + x + 1(4.00)
= 7.00 + x + 4.00
= x + 11.00
Eric paid 3.00: x + 11.00 - 3.00
x + 8.00
Mark paid 11.50 which was the balance owed: 11.50 = x + 8.00
11.50 = x + 8.00
<u>-8.00</u> <u> -8.00 </u>
3.50 = x
the soda cost $3.50
Answer:
x=sqrt(3)/2 or -sqrt(3)/2
Step-by-step explanation:
(x,1/2) is on the unit circle at pi/6 and 5pi/6.
so x is either sqrt(3)/2 or -sqrt(3)/2
