2-3x = -x - 8

Move -x to the other side

Sign changes from -x to +x

2-3x+x= -x+x-8

2-3x+x=-8

2-2x= -8

Move 2 to the other side

2-2-2x= -8-2

-2x= -10

Divide both sides by -2

-2x-2= -10/-2

Answer: x= 5

By what percent will the product of two numbers change, if the first number increases by 70%, while the second number decreases

FinnZ [79.3K]

Answer:

Step-by-step explanation:

Let x be the first number

It increases by 70 %

The new number is

m = x+ .70x

= 1.7x

Let y be the second number

It decreases by 40 %

The new number is

n =y - .40 y

= .6y

The product of the original numbers is xy

The product of the new number is

mn = (1.7x * .6y) = 1.02xy

The new number is larger than the old number so it is an increase.

Percent increase is new - original divided by original times 100%

Percent increase = (1.02 xy - xy)

----------------- * 100%

= .02 xy

------- * 100 %

= .02 * 100 %

= 2%

Allisa [31]

Answer:

Probability of stopping the machine when $X < 9$ is 0.0002

Probability of stopping the machine when $X < 10$ is 0.0013

Probability of stopping the machine when $X < 11$ is 0.0082

Probability of stopping the machine when $X < 12$ is 0.0399

Step-by-step explanation:

There is a random binomial variable $X$ that represents the number of units come off the line within product specifications in a review of $n$ Bernoulli-type trials with probability of success $0.91$ . Therefore, the model is ${15 \choose x} (0.91) ^ {x} (0.09) ^ {(15-x)}$ . So:
