To solve for this, we need to use Pythagorean Theorum.
Pythagorean Theorum is when we add the squares of the legs (A & B) to solve for the hypotenuse (C) or the side that's across from the 90 degree angle.
The formula for Pythagorean Theorum is A^2 + B^2 = C^2.

We have our two leg lengths, 15 and 36 (A & B).
Square 15 and 36.
15^2 = 225
36^2 = 1,296

Now that we have our side lengths, let's add them up.
225 + 1,296 = 1,521.

Now, to solve for C, we need to square root our sum.

The square root of 1,521 is 39.

Your hypotenuse is 39.

Your answer is C.) 39.

I hope this helps!

Elijah bought a total of pounds of peanuts and cashew nuts and paid $49.50. If peanuts cost $2.75 per pound and cashew nuts cost

konstantin123 [22]

Answer:

11 pounds of cashew nuts

Step-by-step explanation:

To solve this problem, we call:

p = number of pounds of peanuts bought

n = number of pounds of cashew nuts bought

We also know that:

- Each pound of peanuts costs $2.75, so the cost of p pounds of peanuts is

$2.75p$

- Each pound of cashew nuts costs $3.25, so the cost of n pounds of cashew nuts is

$3.25p$

So the total cost, which in this case is $49.50, can be written as:

$49.50=2.75p+3.25 n$ (1)

We also know that the total number of pounds is 16, so:

$16=p+n$ (2)

From this equation we get

$p=16-n$

And substituting into (1), we find n:

$49.50=2.75(16-n)+3.25n\\49.50=44-2.75n+3.25n\\5.50=0.5n\\n=\frac{5.50}{0.5}=11$

So, 11 pounds of cashew nuts.

Three students want to estimate the mean word length of the same book. To do this, each student randomly chose 4 words from the

Firlakuza [10]

The solutions to the questions are given below

sample(n) word length sample mean

1 5,4,4,2 3.75

2 3,2,3,6 3.5

3 5,6,3,3 4.25

b)R =0.75

The mean of the sample means will tend to be a better estimate than a single sample mean.
The closer the range of the sample means is to 0, the more confident they can be in their estimate.

<h3>What is the students are going to use the sample means to estimate the mean word length in the book.?</h3>

The table below shows sample means in the table.

sample(n) word length sample mean

1 5,4,4,2 3.75

2 3,2,3,6 3.5

3 5,6,3,3 4.25

Generally, the equation for is mathematically given as

variation in the sample means

R =maximum -minimum

R=4.25-3.5

R =0.75

In conclusion, In most cases, the mean of many samples will provide a more accurate estimate than the mean of a single sample.

They may have a higher level of confidence in their estimate if the range of the sample means is closer to 0 than it is now.
