Drag numbers to use a negative factor to factor the expression-5g+15h-25

Answers

Answer: -5g + 15h - 25 = -5 × (g - h + 5)

Step-by-step explanation:

Step-by-step explanation:

first we do this -5g = -5 × g

then 15h = 5 × 3h

so, -25 = -5 × 5

when -5g + 15h - 25 = -5 × g - (-5 × 3h) + (-5 × 5)

the answer is = -5 × (g - h + 5)

According to the Factors of a Negative Number

First The factors of a number entail all of the numbers that can be multiplied by one another to produce that many numbers.

According to The laws of multiplication that the state when a negative number is multiplied by a positive number then also the product will be negative.

Although when the Factors are those numbers. when it is multiplied with together then the result is another number, which is known as a product.

For a field trip 9 students rode in cars andthe rest filled eight buses. How many
students were in each bus if 265 students
were on the trip?

Answers

Answer:

32 students were on each bus.

Step-by-step explanation:

First deduct 9 students from the total number: 265 - 9 = 256

Then divide the students among the total number of buses, which is 8: 256/8 = 32

So there are 32 students on each bus.

2-23 Ace Machine Works estimates that the probability its lathe tool is properly adjusted is 0.8. When the lathe is properly adjusted, there is a 0.9 probability that the parts produced pass inspection. If the lathe is out of adjustment, however, the probability of a good part being produced is only 0.2. A part randomly chosen is inspected and found to be acceptable. At this point, what is the posterior probability that the lathe tool is properly adjusted?

Answers

Answer:

The posterior probability that the lathe tool is properly adjusted is 94.7%

Step-by-step explanation:

This can be formulated as the following problem:

What is the probability of B happening, knowing that A has happened.

It can be calculated by the following formula

$P = (P(B).P(A/B))/(P(A))$

Where P(B) is the probability of B happening, P(A/B) is the probability of A happening knowing that B happened and P(A) is the probability of A happening.

In your problem we have that:

-A is the probability that the part chosen is found to be acceptable.

The problem states that the probability its lathe tool is properly adjusted is 0.8. When it happens, there is a 0.9 probability that the parts produced pass inspection. There is also a 0.2 probability of the lathe is out of adjustment, when it happens the probability of a good part being produced is only 0.2.

So, P(A) = P1 + P2 = 0.8*0.9 + 0.2*0.2 = 0.72 + 0.04 = 0.76

Where P1 is the probability of a good part being produced when lathe tool is properly adjusted and P2 is the probability of a good part being produced when lathe tool is not properly adjusted.

- P(B) is the the probability its lathe tool is properly adjusted. The problem states that P(B) = 0.8

P(A/B) is the probability of A happening given that B has happened. We have that A is the probability that the part chosen is found to be acceptable and B is the probability its lathe tool is properly adjusted. The problem states that when the lathe is properly adjusted, there is a 0.9 probability that the parts produced pass inspection. So P(A/B) = 0.9

So, probability of B happening, knowing that A has happened, where B is the lathe tool is properly adjusted and A is that the part randomly chosen is inspected and found to be acceptable is:

$P = (P(B).P(A/B))/(P(A)) = (0.8*0.9)/(0.76) = (0.72)/(0.76) = 0.947 = 94.7%$

The posterior probability that the lathe tool is properly adjusted is 94.7%
