Answer:
$7.93
Step-by-step explanation:
20 - 12.07 = 7.93
Option C: 6 is the value of ![b(-10)](https://tex.z-dn.net/?f=b%28-10%29)
Explanation:
The given expression is ![b(x)=|x+4|](https://tex.z-dn.net/?f=b%28x%29%3D%7Cx%2B4%7C)
We need to determine the value of ![b(-10)](https://tex.z-dn.net/?f=b%28-10%29)
To find the value of
, let us substitute
in the given expression.
Thus, substituting
in the expression, we have,
![b(-10)=|-10+4|](https://tex.z-dn.net/?f=b%28-10%29%3D%7C-10%2B4%7C)
Adding the terms, we get,
![b(-10)=|-6|](https://tex.z-dn.net/?f=b%28-10%29%3D%7C-6%7C)
Since, we know the absolute rule that
and the simplified expression is of the form
, let us apply the absolute rule in the simplified expression.
Thus, we have,
![b(-10)=6](https://tex.z-dn.net/?f=b%28-10%29%3D6)
Thus, the value of
is 6.
Hence, Option C is the correct answer.
<h3>
Answer: 12.5 (choice C)</h3>
=================================================
We apply the pythagorean theorem to find this answer.
a = 11 and b = 6 are the given legs
c = unknown hypotenuse
So,
a^2+b^2 = c^2
c = sqrt( a^2+b^2 )
c = sqrt( 11^2 + 6^2 )
c = sqrt( 121 + 36 )
c = sqrt( 157 )
c = 12.52996 approximately
c = 12.5
Side note: once you replace 'a' and b with 11 and 6, you can compute everything with a calculator in one single step more or less. The steps above are shown if you wanted to find the exact value sqrt(157).
The upper 70th percentile is the number below which 70% of the data lie.
The 70th percentile position is given by:
![P_{70}= \frac{70N}{100} = \frac{70(36)}{100} =25.2](https://tex.z-dn.net/?f=P_%7B70%7D%3D%20%5Cfrac%7B70N%7D%7B100%7D%20%3D%20%5Cfrac%7B70%2836%29%7D%7B100%7D%20%3D25.2)
Thus, the 70th percentile position is approximately the 25th data item (after the data has been arranged in acsending order).
Given the following data:
<span>16 24 25 26 27 29 36 39 39 39 40 44 45 47 47 48 50 51 51 53 53 54 57 58
58 60 65 66 67 69 69 71 72 74 74 74
The 25th data in the data set is 58.
Therefore, the upper P70 is 58.
