Answer:

D) 12 adult tickets and 4 child tickets

Step-by-step explanation:

I did process of elimination

A) 4*4=16

12*2 = 24

16+24=40 is not equal to 56

B) 8*4=32

8*2=16

32+16= 48 is not equal to 56

C) 10*4=40

6*2=12

40+12=52 is not equal to 56

D) 12*4=48

4*2=8

48+8=56 is equal to 56

Determine the unknown side lengths’ to the nearest tenth. for the first question and also please help with question 6
Levart [38]

Answer:

z =15cm and

y=9.0cm

Step-by-step explanation:

Use sine rule

12/ sin53 = z / sin 90

Z = 12 x sin 90 / sin 53

Z = 15cm

To find y the angle opposite to y will be 180-(90+53)=37º

So

15/sin 90= y/sin37

y= 15 x sin37 /sin 90

y = 9.0cm

A spinner is divided into six equal-sized sectors labeled 1 through 6. Dwayne spins this spinner 12 times. Let X
slavikrds [6]

Answer:

b) μ = 2 and σ = 1.29

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the A spinner is divided into six equal-sized sectors labelled 1 through 6</em>

<em>Given that the probability of labelled '1'</em>

<em>                       </em>p = \frac{1}{6} =0.16

<em>                      q = 1-p =  1- 0.16 = 0.84</em>

Let 'X' be a random variable in binomial distribution

The mean of the binomial distribution

      μ = n p

     μ  =  12 (\frac{1}{6} ) = 2  

<em>The mean of the binomial distribution  = 2</em>

<u><em>Step(ii):-</em></u>

The standard deviation of X

                σ = \sqrt{npq}

               σ = \sqrt{12(0.16)(0.84}

                  σ = 1.269

<em>The standard deviation of the binomial distribution</em>

<em>                </em> σ = 1.269

<u><em></em></u>

<u><em></em></u>
