Hi!

The median would be your best bet at convincing your parents to get you a new bike for $189 because the median which is $179 is the closest value to the one you want.

For mean:
119 + 139 + 149 + 179 + 189 + 199 + 209 = 1183
1183/7 (for the amount you added) = 169

For median:

119, 139, 149, 179, 189, 199, 209.
Find the middle number: 179 (is your median)

For mode:

119, 139, 149, 179, 189, 199, 209
Find the number that shows up the most: N/A (they all only show up once)

I believe Median will be your best choice (it has the closest answer to 189)

hope this helps

Answer:

The degrees of freedom associated with this problem are 16.

Step-by-step explanation:

The degrees of freedom associated with a problem, independent of the confidence level, is the sample size subtracted by 1.

In this problem, we have that:

She takes a random sample of 17 trucks, so the sample size is 17.

This means that the degrees of freedom associated with this problem are 16.

(Number 5)help plzzz

Answer:

See below.

Step-by-step explanation:

So we want to prove that:

$\sqrt8+\sqrt2=3\cdot 2^{\frac{1}{2}}$

First, simplify √8. This is the same as:

$\sqrt8=\sqrt{4\cdot 2}=\sqrt4\cdot\sqrt2=2\sqrt2$

Therefore, our equation is now:

$2\sqrt2+\sqrt2=3\cdot2^{\frac{1}{2}}$

Combine like terms on the left:

$3\sqrt2=3\cdot 2^\frac{1}{2}}$

The square root of something is the same as taking that number to the one-half power. Thus:

$3(2)^\frac{1}{2}}=3\cdot 2^\frac{1}{2}}$

Rewrite:

$3\cdot2^\frac{1}{2}}\stackrel{\checkmark}{=}3\cdot2^\frac{1}{2}}$

And we're done!

The area of a rectangular field is 8624 yd^2. If the length of the field is 98 yards, what is its width

Maslowich

A = L x W

$8624 = 98 \times w \\ 8624 \div 98 = w \\ 89.83 = w$
so the with is 89.83 yards.
