Mathematics

Scilla [17]3 years ago
7 0

The equivalent expression to (4-7)(2x-1)  is -6x+3

First, you multiply the binomials using the multiplying binomial that you are used to. I like to use the box method.

Multiply 4 by 2x and -1      and multiply -7 by 2x and -1

8x-14x-4+7

Then, add like terms.

-6x+3

Ganezh [65]

Correlation coefficients are expressed by a number between -1 and 1.

If the value is -1 or 1 it indecates a perfect (negative and positive) correlation.

If the value is 0 indicates null correlation.

As the correlation value for you data set is -0.833 it is very close to the -1. It indicates a good correlation in the data. Then, the value you predicted is reasonably close to the actual value.

FinnZ [79.3K]
4 x 1,151.65 = 4,606.60 
<span>This is invested in two accounts. Twenty-five percent is invested in savings (4,606.60 x 25% = 1,151.65). The remainder is invested in a CD (4,606.60 - 1,151.65 = 3,454.95) </span>

<span>Interest accrued for CD </span>
<span>3,454,95 x 0.043 x 60/360 = $24.76 </span>
<span>Total interest accrued </span>
