Answer:

-16

Step-by-step explanation:

Subtract all the numbers to get -112.

To find the mean (average) you need to divide by the amount of values in your data set, in this case 7.

-112 ÷ 7 = -16

Jessica invests​ $250 each quarter in an ordinary annuity with a​ 5% interest rate compounded quarterly. Determine the accumulat
madam [21]

Answer:

Step-by-step explanation:

Usimg formula for calculating compound interest.

A = P(1+r/n)^nt

P is the principal =$250

r is the rate = 5%

t is the time = 25years

n = 1/4(compounded quarterly)

Substituting to get the amount A.

A = 250(1+5/25)^25/4

A = 250(1+0.2)^6.25

A = 250(1.2)^6.25

A = 250(3.125)

A = $781.31

Hence the accumulated amount in​ Jessica's annuity after 25 years is $781.31

Factor........................
elena55 [62]

For this case we have a quadratic polynomial given by:


6x ^ 2-7x-5

Where:


a = 6\\b = -7\\c = -5

We must factor, for this we follow the steps below:


Step 1:


The term of the medium must be rewritten as the sum of two terms, whose sum is -7 and the product is a.c = 6 * (- 5) = - 30:


Then, the term of the medium, fulfilling the two previous conditions, can be written as:


-10x + 3x

We check:


-10 * 3 = -30\\-10 + 3 = -7

So, we have:


6x ^ 2-10x + 3x-5

Step 2:


The maximum common denominator (the largest integer that divides them without leaving residue) of each group is factored


6x ^ 2-10x + 3x-5\\2x (3x - 5) + 1 * (3x - 5)

Step 3:


We take common factor (3x - 5):


(3x - 5) (2x + 1)

Thus, the expression 6x^2-7x-5can be factored as:


(3x - 5) (2x + 1)

Answer:


(3x - 5) (2x + 1)
