Hey there,

<span>Summarize categorical data for two categories in two-way frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data.

Hope this answer has helped you...

The midsegment theorem says that the midsegment is half the third side and parallel as well. 20*2 is 40 so x = 35

The dataset Restaurant Tips contains data recorded from 157 restaurant bills at a bistro in New York over a two week period and

xz_007 [3.2K]

Answer: ($3.532, $4.166)

Step-by-step explanation:

Given : Significance level : $\alpha: 1-0.90=0.10$

Critical value : $z_{\alpha/2}=1.645$

Sample size : n= 157

Sample mean : $\overline{x}=\$\ 3.849$

Standard deviation : $\sigma= \$\ 2.421$

The confidence interval for population mean is given by :_

$\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}$

$\text{i.e. }\$\ 3.849\pm (1.64)\dfrac{2.421}{\sqrt{157}}\\\\\approx\$\ 3.849\pm0.317\\\\=(\$\ 3.849-0.317,\$\ 3.849+0.317)=(\$\ 3.532,\$\ 4.166)$

Hence, the 0% confidence interval for the average tip given at this restaurant = ($3.532, $4.166)

Given m ll n,<br> find the value of x and y.<br> Can someone answer this today please

Artemon [7]

Answer:

x = 15, y = 50

Step-by-step explanation:

m and n are parallel and cut by a transversal

<u>Finding x</u>

8x + 12 + 2x + 18 = 180 (consecutive interior angles sum up to 180°)
10x + 30 = 180
10x = 150
x = 15

<u>Finding y</u>

8x + 12 = 3y - 18 (vertical angles are equal)
8(15) + 12 = 3y - 18
132 = 3y - 18
150 = 3y
y = 50
