PLEASE HELP!!! In a set of 1,000 integers from 1 to 1,000, an integer chosen at random on a single trial should be an integer fr

om 1 to 25 about 25 out of every 1,000 trials, or one out of every 40 integers selected. A sample of 5 integers selected is shown. Does this sample represent the general rule for picking an integer from 1 to 25 in the population of integers from 1 to 1,000?
A. Yes - the sample is representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be none or zero.
B. No - the sample is not representative of the expected number of integers from 1 to 25 in a sample of 5 integers, which would be at least 10.

You are applying fertilizer to a football field. The field is 360 feet long and 160 feet wide. You use 8 pounds of fertilizer pe
Assoli18 [71]

Answer: 10 bags

Step-by-step explanation:

First we must calculate the field area. Assuming it is a rectangle then its area equals the product of its length times its width

A =360*160\\\\A = 57600 ft^2

You use 8 pounds of fertilizer per 1,000 square feet

So the amount of fertilizer you should use is:

57,600 ft^2 * \frac{8\ pounds}{1,000\ ft^2} = 460.8\ pounds

As the fertilizer comes in bags of 50 pound then you need

460.8\ pounds * \frac{1\ bag}{50\ pounds} = 9.2\ bags

Since you can not buy 9.2 bags then we round up to the next whole number.

Finally you need 10 bags of fertilizer

How do you factor 1/4(-16x+8)?​
Nikitich [7]
We know that we can take 4 out of (-16x + 8) [ we know this because we can divide 16 by 4 ( to get 4 ) and we can divide 8 by 4 ( to get 2 ) ]

we can factor out a 4 then from the parentheses to get 4(-4x + 2), but since we are multiplying by 1/4 we get

1/4(4)(-4x + 2), and since 1/4 * 4 = 1, our final answer is

-4x + 2

Would really love some help, 20 points
Vilka [71]

Answer:

x=23.78 cm

Step-by-step explanation:

As this problem is involving the adjacent and hypotenuse sides, we will be using the cosine function

We can setup an equation as follows

cos(18)=\frac{x}{25}

We can now solve for x

x=25cos(18)\\\\x=23.776

This rounds to

x=23.78
