Which point on the graph is a direct variation equation in which k=12.4

Mathematics
1 answer:
frez [133]3 years ago
4 0

Answer:

The correct answer would be A) (4, 49.6)

Step-by-step explanation:

In order to find the equation, we first have to start with the base form of direct variation.

y = kx

Now we input the k value.

y = 12.4x

Now that we have this, we can try the ordered pairs and look for which satisfies the equation.

y = 12.4x

49.4 = 12.4(4)

49.4 = 49.4

Since this is the true statement, this is the ordered pair that works.

What is 18 expressed as a percent?
andriy [413]
Your answer would be 18.00%, because 18 is not a decimal, and you add .00 at the end of it to make it an official percent.

Pavlova-9 [17]

Answer:

SE = 0.025

Step-by-step explanation:

We are given;

Sample mean; x¯ = 14.52

Sample standard deviation; s = 0.075

Sample size; n = 9

Now,formula for standard error of sample mean is;

SE = s/√n

SE = 0.075/√9

SE = 0.075/3

SE = 0.025

Provide the answer as a decimal​
olga55 [171]

Answer:

0.55

Step-by-step explanation:

The right-hand column of the table gives us the probabilities of the probability function. We know from elementary probability theory that the "probability" of any event(s) happening would be from 0 to 1 inclusive.

The total probability of all events would add up to 1. So, we look at the probabilities given for each even, x, and add them:

0.29 + 0.09 + 0.03 + 0.04 = 0.45

All of these probabilities and the probability at x = 2 (the unknown) would add up to 1, so we can say:

0.45 + probability (x = 2) = 1

Probability at x = 2 = 1 - 0.45 = 0.55
