Answer:
x = 15°
Step-by-step explanation:
Due to Alternate Exterior Angles, we can tell that '5x = 75'. Now, let's simplify x.
=> 5x = 75
=> 5x/5 = 75/5
=> x = 15
Therefore, 'x = 15°'
Hoped this helped.
Firstly, we have to find the mean. The mean is simply the average of the numbers, which we find by adding each number in the sequence and then dividing that result by the total amount of numbers.
<em>13.3 + 14.3 + 15.3 + 16.3 + 17.3 = 76.5</em>
<em>76.5 / 5 = 15.3
</em>Okay, so our average is 15.3.
<em>
Now, </em>we have to subtract the mean from each number and then square the result.
<em>(13.3 - 15.3)^2 = 4</em>
<em>(14.3 - 15.3)^2 = 1</em>
<em>(15.3 - 15.3)^2 = 0</em>
<em>(16.3 - 15.3)^2 = 1</em>
<em>(17.3 - 15.3)^2 = 4
</em>Now we have to find the mean of those numbers!
<em>
4 + 1 + 0 + 1 + 4 = 10
10 / 2 = 2
</em>Finally, we take the square root of that number and we have our standard deviation. =)<em>

This question requires you find the total cost per case
28x=252
divide 28 from each side
x=9
Multiply 9 by 10 to get your answer of $90
I'm guessing D, but no so sure.
