Ok, so we know the slope-intercept form of a line, y=mx+b, with m being the slope and b being the y-intercept. We know that the y-intercept has to be negative, so that means A is not a viable option. We also know that the slope is up 4 units and to the right 1 unit. Therefore, the slope is (rise over run) +4/+1, or 4. Therefore, C is your best answer.

You roll 4 fair, distinguishable, six-sided dice. What is the probability of rolling :______

Vikentia [17]

Answer:

a)0.25

b)0.375

Step-by-step explanation:

Possible outcomes when dice are rolled : 1 ,2 ,3,4,5 ,6

Even= 2,4,6

Odd = 1 ,3 , 5

Probability of getting even = $\frac{3}{6}=\frac{1}{2}$

Probability of getting odd = $\frac{3}{6}=\frac{1}{2}$

4 dices are rolled together

a)P(3 even and 1 odd numbers)

P(3 even and 1 odd numbers)= $^4C_3 (\frac{1}{2})^3 (\frac{1}{2})^1$

P(3 even and 1 odd numbers)= $\frac{4!}{3!1!} (\frac{1}{2})^3 (\frac{1}{2})^1 =0.25$

b)P(2 even and 2 odd numbers)

P(2 even and 2 odd numbers)= $^4C_2 (\frac{1}{2})^2 (\frac{1}{2})^2$

P(3 even and 1 odd numbers)= $\frac{4!}{2!2!} (\frac{1}{2})^2 (\frac{1}{2})^2$ =0.375

Someone please answer<br> 2.1 ( x + 5 ) = 7

tatuchka [14]

Since we have the 2.1 next to the parenthesis, we need to first distribute.

2.1 * x & 2.1 * 5

2.1x + 10.5

Then we take that and add the equals seven to the problem to move onto the next step.

2.1x + 10.5 = 7

We must get the 2.1x alone, therefore subtracting the 10.5 as it will also be subtracted on the other side as well.

2.1x + 10.5 = 7
- 10.5 -10.5

2.1x = -3.5

To get the x alone, we must divide both sides by 2.1, therefore removing the 2.1 from the x.

2.1x = -3.5
/2.1 /2.1

x = 1.66666666667

Hope this helped!

The U.S. Department of Housing and Urban Development publishes data on the fair market monthly rent for existing one-bedroom hou

Aleksandr [31]

Answer:

$n=(\frac{1.960(80)}{25})^2 =246.73 \approx 247$

So the answer for this case would be n=247 rounded up to the nearest integer

Step-by-step explanation:

We know that the standard deviation is :

$\sigma = 80$ represent the deviation

The margin of error is given by this formula:

$ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (a)

And on this case we have that ME =25 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=(\frac{z_{\alpha/2} \sigma}{ME})^2$ (b)

The critical value for 95% of confidence interval now can be founded using the normal distribution and the critical value would be $z_{\alpha/2}=1.960$ , replacing into formula (b) we got:

$n=(\frac{1.960(80)}{25})^2 =246.73 \approx 247$

So the answer for this case would be n=247 rounded up to the nearest integer
