Substitute the values of x, y and z to the expression:

$x=-1,\ y=-8,\ z=\dfrac{1}{4}\\\\xyz=(-1)(-8)\left(\dfrac{1}{4}\right)=(8)\left(\dfrac{1}{4}\right)=\dfrac{8}{4}=2$

A politician wants to estimate the proportion of constituents favoring a controversial piece of proposed legislation. suppose th

Volgvan

Answer:

We are given:

Confidence level = 99%. Therefore, the critical value at 0.01 significance level using the standard normal table is given below:

$z_{\frac{0.01}{2}}=2.576$

Margin of error is given in the question as:

$E=0.05$

Since the previous proportion is not given, therefore, we need to assume $\hat{p} = 0.5$

Therefore, the sample size is:

$n=\hat{p}(1-\hat{p}) \left( \frac{z_{\frac{0.01}{2}} }{E} \right)$

$=0.5(1-0.5) \left( \frac{2.576}{0.05} \right)$

$=0.25 \times 51.52^2$

$=663.6 \approx 664$

Therefore, 664 sample observations are required.

Stacey is selling tickets to the school play. The tickets are $8 for adults and $3 for children. She sells twice as many adult t

Leona [35]

48 adult tickets and 24 children tickets were sold.

Step-by-step explanation:

Given,

Cost of one adult ticket = $8

Cost of one child ticket = $3

Total worth of sold tickets = $456

Let,

Number of adult tickets sold = x

Number of child ticket sold = y

According to given statement;

8x+3y=456 Eqn 1

x = 2y Eqn 2

Putting value of x from Eqn 1 in Eqn 2

$8(2y)+3y=456\\16y+3y=456\\19y=456$

Dividing both sides by 19

$\frac{19y}{19}=\frac{456}{19}\\y=24$

Putting y=24 in Eqn 2

$x=2(24)\\x=48$

48 adult tickets and 24 children tickets were sold.
