Kamila [148]3 years ago

Answer:

x-intercept (2,0) or x=2

y-intercept (0,-4) or y=-4

Step-by-step explanation:

4x-2y>8

2x-y>4

2x-4>y

y<2x-4

y=2x-4

when y=0

2x=4

x=2

x-intercept is (2,0)

and y-intercept is (0,-4)

put x=0,y=0

0-0>8

or 0>8 which is not true. so (0,0) does not lie on the graph.

so graph lies right of the line .

4 letters are typed, without repetition. What is the probability that all 4 will be vowels? Write your answer asa percent. Round

Marysya12 [62]

There are 26 letters in the alphabet, 5 are vowels, therefore, the probability of choosing a vowel the first time is:

$\frac{5}{26},$

and the second time is:

$\frac{4}{25}\text{.}$

Continuing with this reasoning, we get that the probabilities each time are:

$\frac{5}{26},\frac{4}{25},\frac{3}{24},\frac{2}{23}\text{.}$

Finally, the probability that you get all vowels is the product of the probabilities:

$\frac{1}{2990}\text{.}$

Writing the above result as a percentage we get:

$0.033\%.$

Answer:

$0.033\%\text{.}$

ANTONII [103]

Answer:

$722444.49386776

Step-by-step explanation:

Use Compound Intrest Formula

$a = p(1 + \frac{r}{n} ) {}^{nt}$

where p is the original amount.
R is the amount of percentage compounded
N is amount of times compounded per year.
T is how long the interest last.

P is 400,00p

T is 12% or 0.12

N is 4 since it is compounded quarterly

T is 5.

Plug the values in

$400000(1 + \frac{0.12}{4} ) {}^{20}$

Ypu get

$722444.49386776

krek1111 [17]

Answer:

72 cans

Step-by-step explanation:

step 1

Find the number of people

we know that

She ordered 1 pizza for every 4 people

using proportion

Find out the number of people for 6 pizzas

$\frac{1}{4}=\frac{6}{x}\\\\x=24\ people$

step 2

Find the number of cans ordered

we know that

Charissa ordered 3 cans of lemonade for each person

using proportion

Find out the number of cans of lemonade she ordered for 24 people

$\frac{3}{1}=\frac{x}{24}\\\\x=24(3)\\\\x=72\ cans$
