Answer:

Step-by-step explanation:

You need to first put the numbers in suitable catagories

0-120

120-130

130-140

140-150

then figure out the frequency of them

0-120=4

121-130=20

131-140=2

141-150=2

then put in a graph(sry its not very good i was in a rush)

I will give brainliest to the first person who answers.

nasty-shy [4]

Answer:

the answer is $\sqrt{5\\}$ , and - $\sqrt{5\\}$ which is C.

Step-by-step explanation:

well I got that answer by doing this

we have $x^{2}$ = 5

For $x^{2}$ = f (a) the solutions are x = $\sqrt{f(a)\\}$ , - $\sqrt{f(a)\\}$

so in this case the solutions are $\sqrt{5\\}$ , and - $\sqrt{5\\}$

HOPE THIS HELPS :)

A movie theater has a seating capacity of 329. The theater charges $5.00 for children, $7.00 for students, and $12.00 of adults.

kipiarov [429]

Answer:

170 children

74 students

85 adults

Step-by-step explanation:

Given

Let:

$C = Children; S = Students; A = Adults$

For the capacity, we have:

$C + S + A = 329$

For the tickets sold, we have:

$5C + 7S + 12A = 2388$

Half as many as adults are children implies that:

$A = \frac{C}{2}$

Required

Solve for A, C and S

The equations to solve are:

$C + S + A = 329$ -- (1)

$5C + 7S + 12A = 2388$ -- (2)

$A = \frac{C}{2}$ -- (3)

Make C the subject in (3)

$C = 2A$

Substitute $C = 2A$ in (1) and (2)

$C + S + A = 329$ -- (1)

$2A + S + A = 329$

$3A + S = 329$

Make S the subject

$S = 329 - 3A$

$5C + 7S + 12A = 2388$ -- (2)

$5*2A + 7S + 12A = 2388$

$10A + 7S + 12A = 2388$

$7S + 22A = 2388$

Substitute $S = 329 - 3A$

$7(329 - 3A) + 22A = 2388$

$2303 - 21A + 22A = 2388$

$2303 +A = 2388$

Solve for A

$A = 2388 - 2303$

$A = 85$

Recall that: $C = 2A$

$C = 2 * 85$

$C = 170$

Recall that: $S = 329 - 3A$

$S = 329 - 3 * 85$

$S = 329 - 255$

$S = 74$

Hence, the result is:

$C = 170$

$S = 74$

$A = 85$

David's dinner cost $24. He wants to leave a 20% tip. The tax rate is 8%. What is the total he will pay? (not $31.10)

Hitman42 [59]

Answer:

$30.72

Step-by-step explanation:

You were right with your answer, the teacher is probably just wanting you to tip on the subtotal (before tax) instead of the total total. Instead of doing total+tax+tip, we're going to figure out the tax and tip separately and then add it all together.

<u>Tipping on the subtotal (what your teacher wanted)</u>

20% of $24 = $4.80

8% of $24 = $1.92

$24+$4.80+$1.92=$30.72

<u>Tipping on the total (what you did)</u>

8% of $24 is $1.92

New total is $25.92

20% of $25.92 is $5.18

$25.92 + $5.18 = $31.10
