Answer:

Step-by-step explanation:

$2^{3} + 3^{2} - 3$ × $4-5^{2}$ ÷ 5 + (7×4)

To solve this equation, we need to use GEMDAS. < That shows us the order of operations for this problem.

G is for grouping. This can be (), {}, or []. There is one grouping in the given equation, (7x4). Now, you just multiply inside of the equation, giving you 28.

Now the equation looks like $2^{3} + 3^{2} - 3$ × $4-5^{2}$ ÷ 5 + 28

E is for exponents. These are numbers that are multiplied to a power. ( $x^{2}$ ). There are three terms with exponents in this equation, $2^{3}$ , $3^{2}$ , and $5^{2}$ . Now, just multiply to the powers giving you 8, 9, and 25.

Now the equation looks like

8 + 9 - 3 x 4 - 25 ÷ 5 + 28

M is for multiply. This is any number times another one. There is only one term that needs to be multiplied in this equation, 3 x 4. Now, just multiply the terms to get 12.

Now the equation looks like

8 + 9 - 12 - 25 ÷ 5 + 28

D is for divide. This is any term that needs to be divided. There is only one in this equation, 25÷5. Now, just divide those terms to get 5.

Now your equation looks like

8 + 8 - 12 - 5 + 28

A is for add. This is any term that needs to be added. There are two in this equation, 8+8. and 5+28. Now, just add to get 16 and 33.

Now your equation looks like

16 - 12 - 33

S is for subtract. This is any term that needs to be subtracted. These are the remaining three in the equation, 16 - 12 - 33. Now just subtract to get -33.

Now that you have completed all of the steps, your final answer is

-33

At Munder Difflin Paper Company, the manager Mitchell Short randomly places golden sheets of paper inside of 30% of their paper

Korvikt [17]

Answer:

90.67% probability that John finds less than 7 golden sheets of paper

Step-by-step explanation:

For each container, there are only two possible outcomes. Either it contains a golden sheet of paper, or it does not. The probability of a container containing a golden sheet of paper is independent of other containers. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

At Munder Difflin Paper Company, the manager Mitchell Short randomly places golden sheets of paper inside of 30% of their paper containers.

This means that $p = 0.3$

14 of these containers of paper.

This means that $n = 14$

What is the probability that John finds less than 7 golden sheets of paper?

$P(X < 7) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6)$

In which

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{14,0}.(0.3)^{0}.(0.7)^{14} = 0.0068$

$P(X = 1) = C_{14,1}.(0.3)^{1}.(0.7)^{13} = 0.0407$

$P(X = 2) = C_{14,2}.(0.3)^{2}.(0.7)^{12} = 0.1134$

$P(X = 3) = C_{14,3}.(0.3)^{3}.(0.7)^{11} = 0.1943$

$P(X = 4) = C_{14,4}.(0.3)^{4}.(0.7)^{10} = 0.2290$

$P(X = 5) = C_{14,5}.(0.3)^{5}.(0.7)^{9} = 0.1963$

$P(X = 6) = C_{14,6}.(0.3)^{6}.(0.7)^{8} = 0.1262$

$P(X < 7) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) + P(X = 5) + P(X = 6) = 0.0068 + 0.0407 + 0.1134 + 0.1943 + 0.2290 + 0.1963 + 0.1262 = 0.9067$

90.67% probability that John finds less than 7 golden sheets of paper

Last season Ellen and Janet together won 32 tennis matches Ellen won 6 more than then Janet How many more matches did Ellen win

joja [24]

T = J + E

T = J + (J + 6)

T = 32

32 = 13 + (13 + 6)

32 = 13 + 19

32 = 32

Ellen won 19 matches.
