Write a recursive formula for the arithmetic sequence: 7,4,1,-2

2 answers:

3 0

A1 = 7
a(sub)n = a(sub)n-1 - 3

(sub) indicates the values touching the parenthesis are written as a subscript.

The above would be the recursive formula as you are taking the previous number and subtracting 3 to get the next number in the sequence.

Answer:

N - 3

Step-by-step explanation:

It is a series of -3 so:

7 -3 = 4

4 - 3 = 1

1 - 3 = -2

So:

N-3

where N is the present value in the sequence.

If m∠agh = 4x and m∠ghd = 3x + 40, what is the value of x?

Mariulka [41]

I am attaching the full question...

Because AB is parallel to CD, the transversal line EF creates the same angles in AB and CD.

This means that 3x+40 = 4x

..........==>> x = 40 degrees

Joe is considering pursuing an MBA degree. He has applied to two different universities. The acceptance rate for applicants with

ANEK [815]

Answer:

The probability that Joe will be accepted at one and only one university

P(A n B ) = 0.1

Step-by-step explanation:

Given data the acceptance rate for applicants with similar qualifications is 25% for University A

P(A) = 25% =0.25

The acceptance rate for applicants with similar qualifications is 40% for University B

P(B) = 40% =0.40

<u>Independent events:</u>

let E and F are said to be independent events then

P(E n F ) = P(E ) P(F)

both universities are independent

The probability that Joe will be accepted at one and only one university

P(A n B ) = P(A) P(B) = 0.25 X 0.40 = 0.1

Stephen spends 10% of his salary on food, 15% of it on transportation, and saves the remaining 2000. what is his salary?

Ber [7]

Answer:

His salary is $2666.68

Step-by-step explanation:

First add the percent of the costs. 10% + 15% = 25%

Then subtract 25% from 100% to find the percentage that 2,000 is of the total salary. 100% - 25% = 75%

$2,000 is 75% of the total salary. Divide 2,000 by three to find the amount of money 25% of the salary is. ( 75% is 3/4 of 100) 2,000 divided by 3 = $666.67

25% of the salary is $666.67

Multiple that by 4 and you get the total salary.

666.67•4= $2666.68

Are you sure those were all the correct numbers because that was not a very nice number at the end there lol but that answer is correct with the numbers you gave me.
