Its the 1st answer: A
Step-by-step explanation:
I already knew this.
Answer:
2 - 79 years is the mean and 82 years is the median.
Step-by-step explanation:
In a given skewed to the left graph, to be able to distinguish between the two measures of center for this expectancy study, the mean is relatively smaller than the median in a skewed left distribution curve.
In this study, The two measures of center for the life expectancy of US males born in the 2018 are 79 years and 82 years. Thus, 79 years is the mean and 82 years is the median.
Add all the like terms
3b + b = b(3 + 1) = 4b
So, 3b + b + 6 = 4b + 6
Answer:
Step-by-step explanation:
The figures dont have enough letters to explain step by step all the exercises.
Bread 1:
The horizontal lines are parallels so both angles must be the same
2x + 21 = 4x - 17
21 + 17 = 4x - 2x
38 = 2x
x = 19
Bread 2:
Angles sum 180°
3y - 5 + 2y - 25 = 180
5y - 30 = 180
5y = 180 +30
5y = 210
y = 42
Bread 3:
Angle ABC is the same as the other 2, since x = 19
ABC = 2x + 21
ABC = 2 * 19 + 21
ABC = 59
Bread 4:
Angle ABC is the same as 3y - 5, y = 42
ABC = 3y - 5
ABC = 3 * 42 -5
ABC = 121
Bread 5:
Angles must be the same
5x - 14 = 2x + 13
5x - 2x = 13 + 14
3x = 27
x = 9
Bread 6:
Angle ABC = 5x - 14 , x = 9
ABC = 5 * 9 - 14
ABC = 31
If you need to understand why the angles must be the same just comment and I will give you more details
