Answer:

yes

Step-by-step explanation:

Direct variation is represented as

y = kx, where k is a constant.

We can rewrite y - x = 0 as

y = x (add x to both sides)

This can be looked at as

y = (1)x , so this is a direct variation relationship where k = 1

From the set 1/2/3/4/5 which values make the inequality n + 1 > true?

saul85 [17]

Hi there!

To make n+1>4 true, you must have n be a numebr greater than 3...

The reason why is because if it is less than 3 or 3, it’ll have to be <.

The two numbers that can make this equation true is 4 and 5...

$4+1=5>4$

$5+1=6>4$

And if it is 1,2, and 3 it would be:

$1+1=2$

$2+1=3$

$3+1=4=4$

Complementary events must have a sum of 1.

Bas_tet [7]

This is a true statement.

Consider two events A and B. We say they are complementary if P(A)+P(B) = 1

This means that either event A or event B must happen, since the "1" represents 100% probability. Having a probability of 100% means absolute certainty.

---------

Example:

A = the event it rains

B = the event it does not rain

P(A) = 0.30 = 30% chance of rain

P(B) = 0.70 = 70% chance it does not rain

P(A)+P(B) = 0.30+0.70 = 1

So this shows the two events are complementary.
