"At least" refers to greater than or equal to (≥).
This is because "at least" means:
- it can't be less than
- it can be equal to
- it can be greater than
This is basically like saying no less than.
If you must have at least 10 oranges for some recipe, then you must have 10 oranges, but you can also have more.
"Twice the difference of a number and 8"
This means that 2 times a number minus 8.
This can be written as 2(w - 8), since w is unknown and it's the difference between w and 8.
The 2 is being multiplied by this because it's 2 times this difference.
"At least 26"
This means ≥ 26.
Now for the actual inequality.
"Twice the difference of a number and 8"
translates to 2(w - 8)
"is at least 26"
translates to ≥ 26
Now put them together.
2(w - 8) ≥ 26
So the answer is 2(w - 8) ≥ 26.
Hope this helps! :)
Answer:
<h3> 20 feet </h3>
Step-by-step explanation:
x - the hight of another sail
Answer:
The degrees of freedom are given by:
And replaicing we got:
The 95% confidence interval would be between 26.9 and 31.1
Step-by-step explanation:
Information given
represent the sample mean
population mean
s represent the sample standard deviation
represent the margin of error
n represent the sample size
Solution
The confidence interval for the mean is given by the following formula:
(1)
And this formula is equivalent to:
![\bar X \pm ME[/te]xThe degrees of freedom are given by:[tex]df=n-1=317-1=316](https://tex.z-dn.net/?f=%20%5Cbar%20X%20%5Cpm%20ME%5B%2Fte%5Dx%3C%2Fp%3E%3Cp%3EThe%20degrees%20of%20freedom%20are%20given%20by%3A%3C%2Fp%3E%3Cp%3E%5Btex%5Ddf%3Dn-1%3D317-1%3D316)
And replaicing we got:
The 95% confidence interval would be between 26.9 and 31.1
This equation is already in slope intercept form.
Slope intercept form is y = mx + b, which is the form it is in now. However, if you would like it changed to standard form, you would multiply by the lowest common denominator and then rearrange as follows.
y = -1/7x + 22/7 -----> Multiply both sides by 7
7y = -x + 22 ------> Add x to both sides
x + 7y = 22
