<h2>Answer:</h2>

The  probability of first drawing a girls name and then a boys name from the hat is:

                \dfrac{9}{55}

<h2>Step-by-step explanation:</h2>

It is given that:

The names of nine boys and two girls are in a hat.

This means that the total number of names in the hat are: 9+2=11.

Also, the probability of first drawing a girls name and then a boys name from the hat is given by:

Probability of drawing a girl name×Probability of drawing a boy name.

Also, the drawing of names is done without replacement.

Hence, we get probability as:

=\dfrac{2}{11}\times \dfrac{9}{10}\\\\=\dfrac{9}{55}

The probability is:  \dfrac{9}{55}

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?
zaharov [31]

After 6 years the investment is $5555.88

Step-by-step explanation:

A principal of $3600 is invested at 7.5% interest, compounded annually. How much will the investment be worth after 6 years?

The formula used to find future value is:

A(t)=P(1+\frac{r}{n})^{nt}

where A(t) = Accumulated amount

P = Principal Amount

r = annual rate

t= time

n=  compounding periods per year

We are given:

P = $3600

r = 7.5 %

t = 6

n = 1

Putting values in formula:

A(t)=P(1+\frac{r}{n})^{nt}\\A(t)=3600(1+\frac{0.075}{1})^{6*1}\\A(t)=3600(\frac{1.075}{1})^6\\A(t)=3600(1.075)^6\\A(t)=3600(1.543)\\A(t)=5555.88

So, After 6 years the investment is $5555.88

Branda and Laurie have rectangular shaped backyards. Branda's yard measures 35 feet by 90 feet. Laurie's yard measures 40 feet b
tia_tia [17]
To find the area of each backyard, we need to multiply the length and width together.

For Branda, her yard is 35 by 90, which means the area is 35*90 which = 3150.

For Laurie, her yard is 40 by 65, which means the area is 40*65 which = 2600.

Now, we are asked to find the difference between Branda and Lauries yard areas. The difference means how much larger Branda's area is than Lauries. 

This means we have to subtract Laurie's area from Branda's.

So, we do 3150 - 2600 = 550 

So, our answer is 550ft^2

Can anyone explain how you graph things for example, like y=x-4 how would you graph that
Savatey [412]

Answer:

In basicallity if a question such as this pops up, the correct way to go would first be to graph this. y=x-4 would be equivalent to x=4.

My paper work is below:

y = x - 4

0 = x - 4

-x = -4

x = 4

Hope this helped..
