Vertical angles are equal

4x = 45 + 15
4x = 60
x = 60/4
x = 15

Firstly,we need to find the sum of opposite angle of 4x,which is 45°+15°=60°

since the right opposite angles have a same degree,the equation would be:

4x=60°
x=60°/4
x=15°

Thus,the answer is 15°

Steph makes 90 % 90%90, percent of the free throws she attempts. She is going to shoot 3 33 free throws. Assume that the results

zmey [24]

Using the binomial distribution, it is found that there is a 0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

For each free throw, there are only two possible outcomes, either he makes it, or he misses it. The results of free throws are independent from each other, hence, the binomial distribution is used to solve this question.

Binomial probability distribution

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

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

The parameters are:

x is the number of successes.

n is the number of trials.

p is the probability of a success on a single trial.

In this problem:

He makes 90% of the free throws, hence $p = 0.9$ .

He is going to shoot 3 free throws, hence $n = 3$ .

The probability that he makes exactly 1 is P(X = 1), hence:

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

$P(X = 1) = C_{3,1}.(0.9)^{1}.(0.1)^{2} = 0.027$

0.027 = 2.7% probability that he makes exactly 1 of the 3 free throws.

Graph the following features:<br> • Slope = 2<br> Y-intercept = -5

Arada [10]

y = mx + b

y = 2x - 5

you can go to desmos calculator online and simply put in the equation. but what you're going to do is find -5 on the y axis. then you will go up 2 and then 1 to the right.

it should look like this:
