Answer:

x=−3 and y=10

Step-by-step explanation:

Let's solve your system by substitution.

x=−3;4x+2y=8

Step: Solvex=−3for x:

x=−3

Step: Substitute−3forxin4x+2y=8:

4x+2y=8

(4)(−3)+2y=8

2y−12=8(Simplify both sides of the equation)

2y−12+12=8+12(Add 12 to both sides)

2y=20

(Divide both sides by 2)

y=10

Julius is buying beverages for brunch. He needs to buy a total of 5

xeze [42]

Well, he only needs 5 gallons of beverages. Because he buys two containers of each, however, that means he bought 320 gallons total (I would say). How I got my answer:

There are 8 pints in a gallon (8 x 2)
There are 4 quarts in a gallon (4 x 2)
There are 16 cups in a gallon (16 x 2)
There are 128 ounces in a gallon (128 x 2)

With that being said, we can add these to find the total amount of gallons of beverages Julius bought. 16 + 8 + 8 + 32 + 256 = 320.

Hopefully this helps!

vDetermine if a Poisson experiment is described, and select the best answer: Suppose we knew that the average number of typos in

goldenfox [79]

Answer:

probability that a randomly selected page that contains only text will contain no typos that is

P(x=0) = $e^{-0.08}$ = 0.923

Step-by-step explanation:

<u>Poisson distribution</u>:-

Explanation of the Poisson distribution :-

The Poisson distribution can be derived as a limiting case of the binomial

distribution under the conditions that

i) p is very small

ii) n is very large

ii) λ = np (say finite

The probability of 'r' successes = $\frac{e^{-\alpha }\alpha^r }{r!}$

Given the average number of typos ∝ = 0.08 per page.

probability that a randomly selected page that contains only text will contain no typos that is = $p(x=0) = \frac{e^{-0.08 }\(-0.08)^0 }{0!}$

After calculation P(x=0) = $e^{-0.08}$ = 0.923

probability that a randomly selected page that contains only text will contain no typos =0.923

PLEASE HELP ME I BEG YOU!!!!!

WARRIOR [948]

You need to find what 34 is 25% of.

I personally would take 34 and divide it by .25 (25%) to get your answer and then to double check it, multiple the answer you get by 25%

$34 \div .25 = 136$
$136 \times .25 = 34$
so originally the farmer had 136 kg of apples of I'm not mistaken.
