10 000 samples wiegh 1 pound.

1 sample would weigh (1 / 10 000) pound

10 samples would then weigh 1 / 10 000 * 10 = 1/1000 = 0.001 Pound

The correct answer is:

1/1000 of a pound.

Explanation:

We will set up a proportion to solve this.

The first ratio of the proportion comes from our given information. 10,000 samples weigh 1 pound; this gives us the ratio 10,000/1.

The second ratio will be set up in the same fashion; in this case, the number of samples over the number of pounds. We know we have 10 samples, but an unknown number of pounds; this means we use a variable to represent the number of pounds:

10/x

This makes our proportion

10,000/1 = 10/x

Cross multiplying, we have

10000(x) = 10(1)

10000x = 10

Divide both sides by 10000:

10000x/10000 = 10/10000

x = 10/10000 = 1/1000

PLease tell me how to do it that will give you brainliest

Evgen [1.6K]

Answer: Table H would be the correct answer;

The rule of a function is that for each x-value given there can't be more than 1 y-value

In Table F:

x = -13, then y = -2

x = -13, then y = 0

x = -13, then y = 5

x = -13, then y = 7

For the x-value -13, there are 4 different y-values, so it's not a function.

In Table G:

x = -6, then y = 3

x = -1, then y = -1

x = -1, then y = 5

x = 10, then y = -9

For the x-value -1, there are 2 different y-values, hence this isn't a function.

In Table H:

x = 1, then y = 4

x = 3, then y = 4

x = 7, then y = 4

x = 12, then y = 4

For each x-value, there is only 1 y-value, so this is a function.

In table J:

x = -9, then y = -7

x = -2, then y = -5

x = 0, then y = 0

x = 0, then y = 6

For the x-value 0, there are 2 different y-value therefore this isn't a function

Hope this helps!

A parking lot has seventy-eight parking spaces numbered from 1 to 78. There are no cars in the parking lot when Jillian pulls in

polet [3.4K]

Answer:

49/78

Step-by-step explanation:

Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.

For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.

probability that the number on the parking space where she parks is greater than or equal to 30 = numbers greater than or equal to 30 / total numbers

Sin 2A + sin A/1+cos A + cos 2A=tan A

Nezavi [6.7K]

Answer:

= 2sinA.cosA+ sinA / 1+cos2A+ cosA

= sinA(2cosA + 1) / 2cos^2A + cosA

= sinA(2cosA + 1) / cosA( 2cosA + 1)

= sinA / cosA

= tan A
