(x² + 2x - 1) - (x² - 2x + 1)

Add like terms.

(x² - x²) + (2x + 2x) + (-1 - 1)

Simplify.

4x - 2

So, the answer is the THIRD CHOICE.

~Hope I helped!~

A sociologist recently conducted a survey of senior citizens who have net worths too high to qualify for Medicaid but have no pr

hjlf

Answer:

a) $s= 9.74$

D. 9.74

b) $Median= 74$

B. 74

Step-by-step explanation:

Part a

We have the following dataset given:

69 74 75 62 70 93 64 69 61 88 67 77 87 90 66 91 77 63 82 82 71 74 76 65 83

We can begin calculating the sample mean with the following formula:

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

And replacing we got:

$\bar X = 75.04$

Now we can calculate the sample deviation with the following formula:

$s =\sqrt{\frac{\sum_{i=1}^n (X_i-\bar X)^2}{n-1}}$

And after replace we got:

$s= 9.74$

Part b

For this case we need to sort the value on increasing way:

[1] 61 62 63 64 65 66 67 69 69 70 71 74 74 75 76 77 77 82 82 83 87 88 90 91 93

And the median would be the value in the position 13 and we got:

$Median= 74$

У = 3х +8<br> What is the x-intercept?

m_a_m_a [10]

Answer:

-8/3

Step-by-step explanation:

To solve for x-intercept, we set y as 0.

0 = 3x + 8

-8 = 3x

-8/3 = x

The x-intercept of the line is -8/3.
