If y=-8 when x=-2, find x when y=32

Answers

Answer 1

Answer: tryfind the relationships between x and y.
I am sure that it is y=4x because when you multiply 4 to the -2 it becomes -8...
and then you plug in the 32 into the y:
32=4x
then divide 4 from the both sides for the value of x.
x=8

Answer 2

Answer: y = -8 when x = -2
y = 32 when x = 8

Fred got a score of 80 on the test. Enter a division sentence using negative numbers where the quotient represents the number of questions Fred answered incorrectly on the test.

Answers

The division sentence using negative numbers where the quotient represents the number of questions Fred answered incorrectly on the test is 20 ÷ (-1) = -20.

Let "x" represent the number of questions Fred answered incorrectly on the test.

Since he got a score of 80, then the equation:

Total Questions - Incorrectly Answered Questions = Score

100 - x = 80

To create a division sentence using negative numbers, express this equation in a different form:

x = 100 - 80

Now, subtract:

x = 20

So, a division sentence using negative numbers is:

20 ÷ (-1) = -20

This division sentence represents that Fred answered 20 questions incorrectly on the test.

The number p is 20 more than the number q . using algebra write the relationship between p and q .

Answers

From what we know, p is 20 more than q. So, we can assume p = 20 + q. Q can also be found by subtracting 20 from both sides. So, q = p - 20.

The number of nails of a given length is normally distributed with a mean length of 5 in. and a standard deviation of 0.03 in. In a bag containing 120 nails, how many nails are more than 5.03 in. long?a.about 38 nails
b.about 41 nails
c.about 16 nails
d.about 19 nails

Answers

The length 5.03 inches belonged to the first range of span of standard deviation. The probability of having length below 5.03 is equal to 68%. The proprobability of having length above 5.03 therefore is (100-68)/2 or equal to 16%. 16% of 120 nails given is 19.2 or D. about 19 nails.

Answer:

(D) About 19 nails

Step-by-step explanation:

It is given that mean length= 5 inches and the standard deviation =0.03.
