Slope= $\frac{y_2-y_1}{x_2-x_1}$

We are given two coordinates:
(x1,y1) and (x2,y2)

Plug given numbers into the formula:
$\frac{1-(-3)}{1-(-2)}$

Two "-"'s next to each other make a positive so we add:
$\frac{1+3=4}{1+2=3}$

Final answer: D.
Slope= $\frac{4}{3}$

What is the answer to 6(1+8n)=-39+3n

MissTica

For this case we must simplify the following expression:

$6 (1 + 8n) = - 39 + 3n$

We apply distributive property on the left side of the equation:

$6 * 1 + 6 * 8n = -39 + 3n\\6 + 48n = -39 + 3n$

We subtract 3n from both sides of the equation:

$6 + 48n-3n = -39\\6 + 45n = -39$

We subtract 6 from both sides of the equation:

$45n = -39-6\\45n = -45$

We divide between 45 on both sides of the equation:

$n = \frac {-45} {45}\\n = -1$

Answer:

$n = -1$

Luba_88 [7]

Answer:

The answer is false

Step-by-step explanation:

In a sample above 30 obs like this the confidence interval is defined as

X+- t* (s/sqrt(n)) where X is the mean t the tvalue for a given confidence level, n the size of sample and s standar deviation.

To find de appropiate value of t we must see the T table where rows are degrees of freedom and columns significance level

The significance is obtained:

significance = 1 - confidence level = 1 - 0.9 = 0.10

Degrees of freedom (df) for the inteval are

df = n - 1 = 18 - 1 = 17

So we must look for the value of a t with 17 values and significance of 0.10 which in t table is 1.740 not 1.746 ( thats the t for 16 df)

How many times can 2 go into 245 in fraction form

zzz [600]

Answer:

244 1/1

Step-by-step explanation:

Since 2 goes into 245 122 times with 1 left over, it would be 244 and a whole, it would probably just be 244 and 1/1 or 245 but you asked for fraction so 244 1/1
