Answer:

2x^3 + 5x^2 - x - 6

Step-by-step explanation:

[NOTE]

I am assuming x2 is x^2, if I am wrong about that then please notify me in the comments

[END NOTE]

The parenthesis are implications that we multiply the numbers within them.

Therefore, multiply.

(2x)(x2)

2x^3

(2x)(x)

2x^2

2x^3 + 2x^2

(2x)(-2)

-4x

2x^3+2x^2-4x

(3)(x2)

3x^2

2x^3+2x^2-4x+3x^2

(3)(x)

3x

2x^3+2x^2-4x+3x^2+3x

(3)(-2)

-6

2x^3+2x^2-4x+3x^2+3x-6

Now combine like terms, meaning the numbers with the same endings, you cannot add a number with different exponents and adding numbers with and without a variable.

2x^3 + 5x^2 - x - 6

A company is interested in evaluating its current inspection procedure on large shipments of identical items. The procedure is t
olchik [2.2K]

Answer:

0.91854

Step-by-step explanation:

Given that a  company is interested in evaluating its current inspection procedure on large shipments of identical items.

The procedure is to take a sample of 5 items and pass the shipment if no more than 1 item is found to be defective.

It is known that items are defective at a 10% rate overall.

If X is the number of defectives in the sample of 5, we find that X has two outcomes and each trial is independent of the other

So X is binomial with n =5, and p = 0.10

the probability that the inspection procedure will pass the shipment

= P(X\leq 1)\\ \\= (0.9)^5 + 5 (0.1)(0.9)^4\\= (0.9^4) (0.9+0.5)\\= 0.91854

Which ordered pair in the form (x,y) is a solution of this equation? 7x-5=1
leva [86]
ANSWER

B. (-2,-3)

EXPLANATION

The given equation is

7x - 5y = 1

We want determine which of the ordered pairs is a solution to the given equation.

For point A(-3,-2)

7( - 3) - 5( - 2) = 1

- 21 + 7 = 1

This statement is false.

For option B(-2,-3)

We have

7( - 2) - 5( - 3) = 1

- 14 + 15 = 1


For option C(0,4)

We have

7(0) - 5(4)=1

0 - 20=1


For option D(4,0)

We have

7(4) - 5(0)=1

28 - 0=1

This statement is false.

It takes 24 workers to complete the job in 5 days. How many days would 15 workers take to do the same job, assuming all the work
zimovet [89]

I'm guessing 10 days, since you lost a bit more than half of the workers, and it would take longer for the job to get done.
