Answer:

f(x) = 8 - 1.5x

Step-by-step explanation:

Here, we want to write a function that can be used to describe the x th term of the sequence

Mathematically, this can be calculated by looking at the numbers in the sequence

The difference between each successive term

is -1.5 ( 6.5-8, 3.5 -5)

So the formula for then x th term will be;

f(x) = 8 - 1.5x

where x refers to the number of the term , for example the 4th term

Answer:

-1.5x+9.5

Step-by-step explanation:

-1.5(1)+9.5=8

How to write fractions in simplest form?<br> ( I give brainliest )
diamong [38]

It's pretty easy, take the example of this fraction... \frac{2}{4}

What you do in here is that you note down the <em>factors</em> of 2 and 4 over here.

<u><em>Factors of 2 and 4:</em></u>

2 = 1, 2

4 = 1, 2, 4

Now, you see that the <em>GREATEST</em> Common Factor (GCF) over here is 2.

Now that we see the GCF of 2 and 4 is 2, what you do next is, you have to <u>divide 2 by 2 AND 4</u><u><em>. </em></u>When you do this, you will get your results. 2 = 1 and 4 = 2, now put this in the fraction form again, meaning switch 2 with 1, and 4 with 2 in the fractions... \frac{1}{2}

So your simplified fraction is \frac{1}2}!

The probability that house sales will increase in the next 6 months is estimated to be 0.25. The probability that the interest r
marin [14]

Answer:

0.11

Step-by-step explanation:

Probability that house sale will increase = P(A) = 0.25

Probability that interest rate on house loans will go up = P(B) = 0.74

Probability that either house sales will go up or interest rates will go up = P(A or B ) = 0.89

We have to find the probability that neither house sales nor interest rates will increase. This event is the compliment of the event that either house sales will go up or interest rates will go up.

i.e.

Probability that neither house sales nor interest rates will increase = P(A \cup B)^{c}

P(A\cup B)^{c} = 1 - P(A \cup B)

Using the value of P(A U B), we get:

P(A\cup B)^{c} = 1 - 0.89\\\\ P(A\cup B)^{c} = 0.11

The probability that neither house sales nor interest rates will increase during the next 6 months is 0.11
