Shawna, Ryan, and Dominic ate a whole pizza. Shawna ate 1

mafiozo [28]

Answer:

$\frac{1}{6}$

Step-by-step explanation:

You need to add the amount Shawna & Ryan ate together, then subtract it from 1 to find the amount of pizza that was left for Dominic to eat.

$\frac{1}{3}$ + $\frac{1}{2}$ = ?

Make all the denominators the same to add fractions.

$\frac{1}{3}$ is $\frac{2}{6}$

$\frac{1}{2}$ is $\frac{3}{6}$

$\frac{2}{6}$ + $\frac{3}{6}$ = $\frac{5}{6}$

1 - $\frac{5}{6}$ = $\frac{1}{6}$

Complete Question

The complete question is shown on the first uploaded image

Answer:

The 95% confidence interval is $-0.00870$

Step-by-step explanation:

From the question we are told that

The first sample size is $n_1 = 1068000$

The first proportion $\r p_1 = 0.084$

The second sample size is $n_2 = 1476000$

The second proportion is $\r p_2 = 0.092$

Given that the confidence level is 95% then the level of significance is mathematically represented as

$\alpha = (100 - 95)\%$

$\alpha = 0.05$

From the normal distribution table we obtain the critical value of $\frac{ \alpha }{2}$ the value is

$Z_{\frac{\alpha }{2} } =z_c= 1.96$

Now using the formula from the question to construct the 95% confidence interval we have

$(\r p_1 - \r p_2 )- z_c \sqrt{ \frac{\r p_1 \r q_1 }{n_1} + \frac{\r p_2 \r q_2 }{n_2} }$

Here $\r q_1 = 1 - \r p_1$

=> $\r q_1 = 1 - 0.084$

=> $\r q = 0.916$

and

$\r q_2 = 1 - \r p_2$

=> $\r q_2 = 1 - 0.092$

=> $\r q_2 = 0.908$

So

$(0.084 - 0.092 )- (1.96)* \sqrt{ \frac{0.092* 0.916 }{1068000} + \frac{0.084* 0.908 }{1476000} }$

$-0.00870$

If you can help would that would be amazing

shutvik [7]

Answer:

yes for the first one

because if you take number one for an example and use it for y

1^7*1^7*1^7=1 and 1^7*7*7=1

they both equal one

2.) $\sqrt{x}$

$\sqrt[3]{x}\sqrt[6]{x}=\:x^{\frac{1}{3}}x^{\frac{1}{6}}=\:x^{\frac{1}{3}+\frac{1}{6}}$

$=x^{\frac{1}{3}+\frac{1}{6}}$

join 1/3+1/6= 1/2

then you get the answer

$\sqrt{x}$
