Answer:
B. 1010
Step-by-step explanation:
<u>Simplify:</u>
<u>Note that:</u>
- ab = 10a +b
- ab0 = 10* (10a + b) = 10ab
- ab0ab = 1000ab + ab = 1001 ab
<u>Therefore:</u>
- (ab0+ab0ab) ÷ (ab) - 1 =
- (10ab + 1001ab) ÷ (ab) - 1 =
- (1011ab) ÷ (ab) - 1 =
- 1011 - 1=
- 1010
<u>Correct choice is</u> B.1010
We have five value in the data-set
The third value will be 10 since we want the median to be 10
We want the mean to be 14
To find the mean of a data set, we divide the sum of the values by the number of values
Mean = Sum of values ÷ Number of values
14 = Sum of values ÷ 5
Sum of values = 14 × 5
Sum of values = 70
So we need 5 values that add up to 70, one of the value is 10, which is the median. We would want two values that are smaller than 10 and two values more than 10.
These four value must add up to 70 - 10 = 60
From here we can do trial and error:
Choose any two values less than 10, say 9 and 8
We now have in total 8 + 9 + 10 = 27
We have 70 - 27 = 43 left to find
Choose any two values that are bigger than 10 that add up to 43, for example, 20 and 23
Now we have our 5 values;
8 9 10 20 23
Do the checking bit:
We can see from the set, the median is 10
Mean = [8+9+10+20+23] ÷ 5 = 70 ÷ 5 = 14
We can have values other than 8, 9, 20 and 23 as long as two values smaller than 10 and two values more than 10. All five values must add up to 70.
Answer:
Exterior Angle = 36 degrees
Step-by-step explanation:
<u><em>Each interior angle of a regular decagon measures 144 degrees.</em></u>
=> <u><em>We'll subtract 144 from 180 to get the measure of the exterior angle.</em></u>
=> Exterior Angle = 180-144
=> Exterior Angle = 36 degrees
the pythagorean theorem is a^2+b^2=c^2
You have a and c already, so its 5^2+b^2=13^2
13^2 equals 169. 5^2 equals 25.
You now have 25+b^2=169
169-25=144
The square root of 144 is 12.
The other leg is 12 units
Given the expression:
Let's simplify the expression.
To simplify the expression, we have:
Rewrite y⁸ = (y⁴)²
Thus, we have:
