3. x-2y = 12<br>y=3x+ 14 substitution to solve system of equation

OLEGan [10]

Answer:

$\displaystyle [-8, -10]$

Step-by-step explanation:

12 = x - 2[3x + 14]

12 = x - 6x - 28

12 = −5x - 28

+ 28 + 28

____________

$\displaystyle \frac{40}{-5} = \frac{-5x}{-5}$

$\displaystyle -8 = x$ [Plug this back into both equations above to get the y-coordinate of −10]; $\displaystyle -10 = y$

musickatia [10]

Answer:

a) 0.567

b) (0.5414,0.5926)

c) (0.5364,0.5976)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 1007

Number of respondent that they will be able to afford health insurance in the future, x = 571

a) point estimate of the population proportion

$\hat{p} = \displaystyle\frac{x}{n} = \frac{571}{1007} = 0.567$

b) 90% Confidence Interval.

$\hat{p} + z_{\text{critical}}\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.10} = \pm 1.64$

Putting values, we get,

$0.567 \pm 1.64\times \sqrt{\dfrac{0.567(1-0.567)}{1007}}\\\\0.567 \pm 0.0256=(0.5414,0.5926)$

c) 95% Confidence Interval.

$\hat{p} + z_{\text{critical}}\times \sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}$

$z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.96$

Putting values, we get,

$0.567 \pm 1.96\times \sqrt{\dfrac{0.567(1-0.567)}{1007}}\\\\0.567 \pm 0.0306=(0.5364,0.5976)$

Theo made a donation to a charity. His grandfather agreed to add $4.00 to Theo's donation amount and then donate half of that su

miss Akunina [59]

So you have to solve for "donation" - so let's call that X. And the things we know are what the grandfather donated, as a function - meaning based upon - Theo's donation. We'll call that Y.

So Y is equal to 1/2 of $4 plus Theo's donation...... 0.5*(x+4).

So... 4.25 = 0.5(X+4), solving for X

4.25=0.5x + 2

-2 -2

2.25=0.5x - divide each side by 0.5 to get x alone.

x = 4.50

Plugging back in:

(4.50 + 4.00)*0.5 = 4.25!
