Answer:

I. 1 cup is $4.50

2 cups is $9.00

3 cups is $13.50

ll. 6 cups is $27.00

Step-by-step explanation:

Now since the number of cups is proportional to the total cost of frozen yoghurt,and the cost of 4 yoghurts cups where given .ie. $18.00

then 1 cup is $18/4 which is $4.50 per one cup, thus the other cost of cups are given.

therefore 6 cups is 6•18/4 which is $27.00.

hence 5 cups is 5•18/4 which is $22.50.

Answer:

WX = 7.9

Step-by-step explanation:

By applying tangent rule (law of tan) in the given right triangle WXY.

tan(W) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(27)° = $\frac{\text{XY}}{\text{WX}}$

0.509525 = $\frac{4}{\text{WX}}$

WX = $\frac{4}{0.509525}$

WX = 7.85

WX ≈ 7.9

Therefore, length of side WX is 7.9 units.

Answer:

you are unwilling to predict the proportion value at your school = 0.90

b)

The large sample size 'n' = 864

Step-by-step explanation:

Given estimated proportion 'p' = 10% = 0.10

Given Margin of error M.E = 0.02

Level of significance α = 0.05

you are unwilling to predict the proportion value at your school

q = 1- p = 1- 0.10 =0.90

The Margin of error is determined by

$M.E = \frac{Z_{\frac{\alpha }{2} } \sqrt{p(1-p)} }{\sqrt{n} }$

$0.02 = \frac{1.96 X \sqrt{0.10 (0.90)} }{\sqrt{n} }$

Cross multiplication , we get

$\sqrt{n} = \frac{1.96 X \sqrt{0.10 (0.90)} }{0.02 }$

√n = 29.4

Squaring on both sides , we get

n = 864.36

Conclusion:-

The large sample size 'n' = 864
