Answer:


Step-by-step explanation:

An adult ticket costs $2 more than a child ticket

Let x and (x + $2)represent the cost of the child and adult ticket respectively

2(x+ $2) + 3x = $34

now solving for x

2x+ $4 + 3x = $34

       5x = $30

        x = $6 , the cost of the child ticket.

the cost of adult ticket $6+2=$8

tatyana61 [14]

Answer:

Following are the solution to the question:

Step-by-step explanation:

p = 0.43\\\\n = 243\\\\\sigma =\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.43 (1 -0.43)}{243}}=0.0013

z-score for \hat{p}=0.2 will be:

z score for will be:

z=\frac{\hat{p}-p}{\sigma}=\frac{0.39 - 0.43}{0.0013}=-30.76

P(0.2 using excel method to calculate the value.

Can someone help me do this
SCORPION-xisa [38]

Answer:

6

Step-by-step explanation:

Find the missing angle:

180⁰ - 82⁰ = 98⁰

Find the sum of the angles given without the missing angle:

180⁰ - 98⁰ = 82⁰

The sum of both the angles is 82⁰

Write an equation:

5x + 8 + 6x + 8 = 82⁰

Collect the like terms together

11x + 16⁰ = 82⁰

Subtract 16⁰ from both sides

11x = 66⁰

Divide by 11 on both sides

x = 6⁰

Kevin, can clean a stadium in 5 hours working alone. Chris, can
LenaWriter [7]

Answer: It will about 1.88 hours or 1 hour 52.5 minutes to clean the stadium if they work together .

Step-by-step explanation:

Given : Time taken by Kevin to clean a stadium = 5 hours

Rate of work done by Kelvin =\dfrac{1}{5}

Time taken by Chris to clean a stadium  = 3 hours

Rate of work done by Chris =\dfrac{1}{3}

Let t be the time taken by both of them to clean the stadium together.

According to the question , we have

Rate of work done together = Rate of work done by Kelvin+Rate of work done by Chris

\dfrac{1}{t}=\dfrac{1}{5}+\dfrac{1}{3}\\\\ \Rightarrow\ \dfrac{1}{t}=\dfrac{3+5}{15}\\\\ \Rightarrow\ \dfrac{1}{t}=\dfrac{8}{15}\\\\\Rightarrow\ t=\dfrac{15}{8} =1.875

t=1+0.875 hours

t=1\text{ hour }+0.875(60)\text{ minutes}  [∵ 1 hour = 60 minutes]

t=1\text{ hour }+52.5\text{ minutes}= \text{1 hour 52.5 minutes}

Hence, It will about 1.88 hours or 1 hour 52.5 minutes to clean the stadium if they work together .
