Answer: -2

Step-by-step explanation: In algebra, we use the word slope to describe how steep a line is and slope can be found using the ratio rise over run between any two points that are on that line.

When finding the slope, first look at y-intercept.

We can see that a point crosses it at 2 units up.

From there, the tie it touches a point

would be to the right 1 on the x-axis.

So the slope is -2/1.

Since we go down 2 and to the right 1 or -2.

A recent survey found that 70% of all adults over 50 wear

Answer:

There is an 84.97% probability that at least six wear glasses.

Step-by-step explanation:

For each adult over 50, there are only two possible outcomes. Either they wear glasses, or they do not. This means that we use the binomial probability distribution to solve this problem.

Binomial probability distribution

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

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

In which $C_{n,x}$ is the number of different combinatios of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

In this problem we have that:

$n = 10, p = 0.7$

What is the probability that at least six wear glasses?

$P(X \geq 6) = P(X = 6) + `P(X = 7) + P(X = 8) + P(X = 9) + P(X = 10) = 0.8497$

There is an 84.97% probability that at least six wear glasses.

My best guess is a line graph because it shows the consistent numbers and then you can lay them all out after you have completed the graph

PLZZZ HELP XD WILL GIVE BRAINLIEST WHERE TO PUT THE POINT ON THE NUMBER LINE!!!!!

lana66690 [7]

Every number has its purpose in this case you start at -3 then the negative sign tells you which way you are going but since we have another negative sign in between the number we go to the right instead of left with that said you put the point in number 4
