Solution:
<u>Note that:</u>
- Triangle = 180°
- 5x + 130 + 3x + 2 = 180
<u>Simplify the equation to find x.</u>
- 5x + 130 + 3x + 2 = 180
- => 8x + 130 + 2 = 180
- => 8x + 2 = 180 - 130
- => 8x = 50 - 2
- => 8x = 48
- => x = 48/8 = 6
The value of x is 6.
Answer:
median: 8
mean: 7.7
Step-by-step explanation:
In order to find median (the middle number is a set of data), you need to first put the numbers in order from least to greatest:
4, 5, 8, 8, 10, 11
Since there are two numbers in the middle - 8 and 8, you can add them together and divide by two to get the median:
8 + 8 = 16 ÷ 2 = 8
Mean is the average of the set of data and can be found by finding the sum of the data and dividing by the total number of data points.
4 + 5 + 8 + 8 + 10 + 11 = 46 ÷ 6 ≈ 7.7
Answer:
Step-by-step explanation:
Note the f(0) = 9
and f(1) = 15
Since, f(x) = abˣ substituting for x, we get:
9 = f(0) = a . b⁰ = a
⇒ a = 9
Now, f(1) = 15
⇒ 15 = a . b¹
⇒ 15 = 9 . b
⇒ b = 15/19
Therefore,
f (r) = 9. (5/3)
Hence, the answer.
