Step-by-step explanation:
angle AOB = x+3
angle AOC = 2x + 11
angle BOC = 4x-7
angle AOC = angle AOB + angle BOC
=> 2x +11 = (x+3) + (4x-7)
2x +11 = 5x - 4
=> 3x = 15
x = 5
subst x = 5 in the given formulas
angle AOB = x +3 =8
angle AOC = 2x + 11 = 21
angle BOC = 4x - 7 = 13
Answer:
Base = 3√5
Step-by-step explanation:
Given:
Hypotenuse = 9
Perpendicular = 6
Find:
Base(x)
Computation:
Using Pythagorean theorem
Base = √Hypotenuse² - Perpendicular²
Base = √9² - 6²
Base = √81 - 36
Base = √45
Base = 3√5
Answer:
I can only do mean and median
First, you have to write it in decreasing order
1, 4, 5, 6,7,8,9,9,9,11
Now, we seperate them
1, 4, 5, 6,7,8,9,9,9,11
the two middle numbers are 7 and 8 so the median is 7.5
upper quartile: 8,9,9,9,11
lower quartile: 1, 4, 5, 6, 7
To find the mean, we have to add all the numbers and divide it by the amount of numbers. There are 10 numbers and added togetehr they are 69 so divide 69 by 10 so 6.9 for the mean and 7.5 for median
