Answer:

Step-by-step explanation:

The slope: $m=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{8-6}{8-7}=\dfrac21=2$

y = mx + b ← slope intercept form

(8, 8) ⇒ x = 8, y = 8

so:

8 = 2·8 + b

b = - 8

The equation: y = 2x - 8

What is the solution to the equation x + 14 = 63? (Input a whole number only.) (3 points) Blank 1:

Alex

Hey there!

This is a one-step equation, meaning that we can solve it in one step.

This is the step:

Subtract 14 from both sides

Goal:

To find out the value of x

Subtract 14:

x+14-14=63-14

the 14's on the left cancel:

x=49

Hence, the answer is

$\boxed{\boxed{\bold{x=49}}}$

Hope everything is clear.

Let me know if you have any questions!

According to a survey, 78% of residents in Summerville own a home. If 30 residents

Answer:

0.1732 = 17.32% probability exactly 24 residents own a home.

Step-by-step explanation:

For each resident, there are only two possible outcomes. Either they own a home, or they do not. The probability of a resident owning a home is independent of any other resident. This means that the binomial probability distribution is used to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$
