Answer:

$\huge \boxed{\textnormal{The slope is 2.}}$

Step-by-step explanation:

Slope formula:

$\displaystyle M=\frac{Y_2-Y_1}{X_2-X_1}=\frac{RISE}{RUN}$

$\displaystyle \frac{1-(-5)}{4-1}=\frac{6}{3}=2$

$\large \textnormal{Therefore, the slope is 2, and the correct answer is 2.}$

Please answer this question

USPshnik [31]

Answer:

C - The relationship represents a function because each input gives one unique output.

Step-by-step explanation:

To see if it is a function we can do the line test where we have a vertical line and "drag" it along the line. As long as it only hits the line once in every situation it is a function! We can see this passes and therefore the answer is c.

(why is it not d? you can have a non-linear line, but still have a function)

Solve the equation X/-2=5

Ipatiy [6.2K]

Answer:

$\boxed {x = -10}$

Step-by-step explanation:

Solve for the value of $x$ :

$\frac{x}{-2} = 5$

-Multiply both sides by $-2$

$x = 5 \times (-2)$

$\boxed {x = -10}$

So, therefore, value of $x$ is $-10$ .

A certain company sends 35% of its overnight mail parcels via express delivery service 1 and the rest by express delivery servic

sineoko [7]

Answer:

55.32% probability that a late package was delivered by express delivery service 2

Step-by-step explanation:

Bayes Theorem:

Two events, A and B.

$P(B|A) = \frac{P(B)*P(A|B)}{P(A)}$

In which P(B|A) is the probability of B happening when A has happened and P(A|B) is the probability of A happening when B has happened.

In this question:

Event A: Late delivery.

Event B: Service 2 was used.

A certain company sends 35% of its overnight mail parcels via express delivery service 1 and the rest by express delivery service 2.

100 - 35 = 65%.

So $P(B) = 0.65$

Service 2 has a record of 2.0% of packages being delivered late.

This means that $P(A|B) = 0.02$

Probability of a late delivery.

35% from service 1. Of those, 3% are late.

65% from service 2. Of those, 2% are late.

$P(A) = 0.35*0.03 + 0.65*0.02 = 0.0235$

What is the probability that a late package was delivered by express delivery service 2

$P(B|A) = \frac{0.65*0.02}{0.0235} = 0.5532$

55.32% probability that a late package was delivered by express delivery service 2
