<h3>Answer:</h3>

3) likely

4) 1/2; equally likely

<h3>Step-by-step explanation:</h3>

3) You are being asked to translate a numerical value to a subjective statement. There are no hard-and-fast rules for this. Generally, the meanings of the terms you're asked to choose from are ...

impossible: probability is zero. The outcome cannot occur.
unlikely: chances are less than even; often, "unlikely" means a probability of 10%, 5%, 1% or lower, depending on the context.
equally likely: probability is near 50%
likely: more likely than not. Again, this depends on the context.
certain: probability is 1. There is no chance the outcome will not occur.

An 80% probability is greater than 50%, so might reasonably be called "likely."

___

4) a. Four of the eight numbers are even, so the probability of obtaining an even number at random is 4/8 = 1/2.

b. A probability of 50% might reasonably be called "equally likely", as the probability the event will occur is equal to the probability it won't.

Rectangular implies the area to be length times height

let height=x

let width=2 more than the height or Length=2+x

Area=F(x)=(2+x)(x)=2x+x^2

f(x)=x^2+2x

****************To Answer your Additional question

You see the standard price is $100 for any mural, And also charges $40 per square foot.

So to show you the approach, Lets say that a mural of 1 square feet needs to be painted, then the charge will be $100 plus the $40 for every square feet, then it will be 100+40(1 square feet)=$140.

The problem asks for the charge of mural whose area is x, so lets do the same thing.

$100+40(x square feet)=100+40x and that is the function that gives the price of mural with an area of x.

so, g(x)=100+40x

What is the common difference in the sequence -40,-22,-4,14

mario62 [17]

Answer:

-18

Step-by-step explanation:

This is rather simple is it not?

To find the difference between the numbers, we simply have to subtract one from another. $-40-(-22)$ , which can be simplified into $-40+22$ because subtracting a negative from a negative is simply done by adding the second negative as a positive to the first negative. Therfore $-40+22$ = -18 which is your answer.
