Answer:

Step-by-step explanation:

2(x-3)-5x<9 expand left side

2x-6-5x<9. group like terms on left side

-3x-6<9. add 6 to each side

-3x<15. divide each side by -3 (reverse sign because of division by a negative)

x>-5

Answers

Answer:

15 to10

Step-by-step explanation:

Find 7% of 280
Find 12% of 300
Find 2% of $1250

Answers

percent means parts out of 100
7%=7/100=0.07
'of' means multiply so

7%=0.7
7% of 280=0.07 times 280=196

12%=0.12
12% of 300=36


2%=0.02
2% of $1250=$25

Which of the following types of statement cannot be used to explain the steps of a proof? Check all that apply. A.Postulate B.Guess C.Conjecture D.Theorem

Answers

Answer:

Guess and Conjecture

Step-by-step explanation:

Conjecture is simply an opinion gotten from an incomplete information .Fro example. 10 boys selected from Nigeria were served pizza. None of them ate pizza.

it is a conjecture to conclude that all the males in Nigeria do not eat pizza, because the information is incomplete

Guess is almost similar to conjecture. It is  conclusion from incomplete information. It is based on one's personal opinion. Guess can be true or false. it is underprobaility and hence cant be banked upon to explain a proof.

Answer:

guess, conjecture

4. When interpreting a scatterplot, the association must be positive or negative.True
False

Answers

True True True True True True True True 

The correct answer is:

True.

Explanation:

An association between two variables in a scatterplot is shown by most of the points following a pattern.  This pattern can be linear or non-linear.  The more closely the points seem to follow this pattern, the stronger the association.

An association in a scatterplot can be negative, meaning that as one variable increases the other decreases, or positive, meaning that as one variable increases the other increases as well.  A negative association will appear to decrease on a graph, and a positive association will appear to increase on a graph.

What is the exponential equation for this problem?
What is the decay FACTOR?
What is the decay RATE?

Answers

A  = Ao(x)^t 

Ao = 500

A = 500(x)^t

400 = 500 (x)^1

x = 4/5

A = 500(4/5)^t   << The exp eqn
