Answer:

pls give me brainliest

Step-by-step explanation:

A compound event is an event where there are more than 1 type of possibilities. for example, a non compound event like tossing a coin, has only 2 outcomes, either heads or tails, this is one possibility, but while tossing a die, there are various possibilities, like p(getting 1), p(getting even number), p(getting prime number), etc. this is known as a compound event.

a sample space is is where all outcomes of an event is enlisted, for example in tossing a die, sample space is {1,2,3,4,5,6}. and sample space for tossing a coin, {H,T}. Note : if 2 dices are tossed, the number of possibilities or 6^2, because there are 6 possibilities in one die and it will be 6^2 if there are 2.

a tree diagram helps in easily writing down the outcomes easily, here is an example.

The correct answer is:  [A]:  " - 1 " .
__________________________________________________________
Explanation:
__________________________________________________________
Given:  " If h(x) = -3x <span>−</span><span> 10, find h(-3). "

So; we plug in "-3"  for all values of "x" ; to solve for " h(-3)" ; as follows:

       </span>→  h(-3)  =  -3(-3) − 10 = 9 − 10 = - 1 .

The answer is:  " - 1 " .

A rectangle's area is 6 units larger than its perimeter. The height of the rectangle is 4 units. What is the base of the rectang
choli [55]

The area of a rectangle is the product of its dimensions

The base of the rectangle is 7 units

<h3>How to calculate the base of the rectangle</h3>

The area of a rectangle is:

Area (A) = Base (B) * Height (H)

From the question, we have:

A = 6 + P

H = 4

The perimeter of the rectangle is:

P =2 * (B + H)

So, we have:

P =2 * (B + 4)

Substitute P =2 * (B + 4) in A = 6 + P

A = 6 + 2 * (B + 4)

Expand

A = 6 + 2B + 8

Evaluate

A = 2B + 14

The area of the rectangle is:

A = BH

So, we have

A = 4B

Substitute 4B for A in A = 2B + 14

4B = 2B + 14

Subtract 2B from both sides

2B = 14

Divide both sides by 2

B = 7

Hence, the base of the rectangle is 7 units

write an equation in point-slope form of the line that passes through the point (3, 5) and has a slope or -1
frez [133]

Answer:

y = -x + 8

Step-by-step explanation:

m = -1  ; x1 = 3 ; y1 = 5

Slope point form: y - y1 = m(x -x1)

y - 5 = -1(x - 3)

y -  5 = -1x - 3 *(-1)

y - 5 =-x + 3

    y =  -x + 3 + 5

     y = -x + 8
