3x-4y=22x-4y=-4
x=-4
put in equation 1
3(-4)-4y=2
-12-4y=2
-4y=2+12
-4y=14
y=14 divided by - 4
y=-3.5

Given the following formula, with A = 27 and t = 3, solve for r. <br> A=p(1+rt)

Nookie1986 [14]

Answer:

Step-by-step explanation:

The given formula is

$A=p(1+rt)$

Where $A=27$ and $t=3$

To solve for $r$ , first we need to move $p$

$\frac{A}{p}=1+rt$

Then, we move the term 1

$\frac{A}{p}-1=rt$

Finally, we move the factor $t$

$\frac{\frac{A}{p}-1 }{t} =r$

Replacing given values, we have

$\frac{\frac{27}{p}-1 }{3} =r\\r=\frac{\frac{27-p}{p} }{3} \\r=\frac{27-p}{3p}$

Thereofre, the right answer is A.

A manager for an insurance company believes that customers have the following preferences for life insurance products: 20% prefe

Zanzabum

Answer:

Yes the sales manager claims can be refuted based on the calculated percentages

Step-by-step explanation:

<u>From the table attached below </u>

Total number of customers = 200

<em>Calculated percentages</em><em> </em>

customers that prefer whole life insurance = 90 = 90/200 = 45%

customers that prefer universal life insurance = 15 = 15/200 = 7.5%

customers that prefer Annuities = 95 = 95/200 = 47.5

<em>Expected percentages:</em>

whole life = 20%

Universal life = 10%

Life Annuities = 70%
