il63 [147K]

Answer:

Sylvia's investment would double first

Step-by-step explanation:

The number of years it takes for amount invested to double itself using the 72 rule is 72 divided by rate of interest as computed below:

Sylvia investment:

Sylvia's investment would double in 9 years' time (72/8)

Manuel's investment"

Manuel investment of $600 would double itself in 9.9 years' time (72/7.25)

From the above analysis,Sylvia's investment of $500 at the 8% rate of interest would double first

If a rectangle has an area of 2x^2+7x+3 find the perimeter

Helen [10]

Answer:

Perimeter of the rectangle=6x+8 square units

Step-by-step explanation:

Given that area of rectangle is $2x^2+7x+3$

Area of rectangle=lw square units

$2x^2+7x+3=2x^2+x+6x+3$

$=x(2x+1)+3(2x+1)$

$=(x+3)(2x+1)$

$2x^2+7x+3=(x+3)(2x+1)$

Comparing the above equation with the given area we get

lw=(x+3)(2x+1)

Therefore length=x+3 and width=2x+1

To find the perimeter :

Perimeter of the rectangle=2(l+w) square units

$=2((x+3)+(2x+1))$

$=2(x+3+2x+1)$

$=2(3x+4)$

$=6x+8$

Therefore perimeter of the rectangle=6x+8 square units

REALLY NEED HELP: The Venn Diagram shows a universe with 26 elements and two different outcomes: B and Y

Goshia [24]

Answer:

P(B|Y)=0.4

Step-by-step explanation:

We are given with a Venn diagram of a universe with 26 elements and two different outcomes: B and Y

And we are asked to find P(B|Y)

The formula for P(B|Y)= $\frac{P(B\cap Y)}{P(Y)}$

From Venn diagram, $P(B\cap Y)=\frac{n(B\cap Y)}{26} =\frac{8}{26} =\frac{4}{13}$

And P(Y)= $\frac{n(Y)}{26}=\frac{8+12}{26}= \frac{20}{26}= \frac{10}{13}$

Hence P(B|Y)= $\frac{(\frac{4}{13})}{\frac{10}{13}} =\frac{4}{10}=0.4$
