Answer:

x = 5

y = 40°

Step-by-step explanation:

the median and the base of the large triangle are parallel so angle y has the same measure as the one labeled as 40°

the median is half the base of the large triangle, so 5x = 8x + 10/2

cross-multiply: 10x = 8x + 10

2x = 10

x = 5

Which of the following equations have no solutions? Choose all answers that apply:

Harlamova29_29 [7]

$- 40x + 40 = 20x + 20 \\ - 60x = - 20 \\ x = \frac{1}{3}$

This equation has a solution

$20x + 40 = 40x + 20 \\ - 20x = - 20 \\ x = 1$

This equation has a solution

$- 20x + 40 = - 20x + 20 \\ 0x = - 20$

This equation has no solution

$40x + 40 = 40x + 20 \\ 0x = - 20$

This equation has no solution

A defunct website listed the "average" annual income for Florida as $35,031. What is the role of the term average in statisti

ahrayia [7]

Answer:

For this case the average is an statistic unbiased for the population parameter $\mu$

And the average is calculated with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

Where n represent the sample size

N represent the population size, and X the observations for this case the annual income.

This statistic is an unbiased estimator of the population mean since $E(\bar X) = \mu$

After calculate the average they got:

$\bar X= 35031$

And we can use the term "sample mean" instead of the average, and is a measure of central tendency for the data
