For ABC:
The interior angle of C is 180 - 142 = 38
The three interior angles add up to 180°
(2x - 15) + (x - 5) + 38 = 180
3x - 20 + 38 = 180
3x + 18 = 180
3x = 162
x = 54
The measure of angle ABC = x - 5 = 54 - 5 = 49
For JKL:
The interior angle of L is 180 - 100 = 80°
The 3 interior angles add up to 180°
(2x + 27) + (2x - 11) + 80 = 180
4x + 16 + 80 = 180
4x + 96 = 180
4x = 84
x = 21
The measure of angle JKL is 2x - 11 = 2(21) - 11 = 42 - 11 = 31°
Answer:
12/10 =1.2 - 1 = 0.2 x 100 = 20%
Step-by-step explanation:
Answer:
444,444
Step-by-step explanation:
total amount=737373
jerry=292929
Brandon=unknown
To figure the amount of video games Brandon has, we have to subtract the amount of both he and his friend altogether amount with Jerry's current amount of video games.
737,373-292,929=444,444
So, by subtracting the two, the answer would be 444,444.
Brandons total amount of video games:444,444
Step-by-step explanation:
Let the coordinates of point b be (x,y).
Given the coordinates of a (-7,5) and c(5,-1)
Now according to question
ab = 5bc
using distance formula
Solving we can get
'
However, we do need either x or y coordinate of point b to find the other.
Answer:
The margin of error is multiplied by 
Step-by-step explanation:
margin of error (ME) from the mean can be calculated using the formula
ME=
where
- z is the corresponding statistic of the given confidence level
- s is the standard deviation of the sample (or of the population if it is known)
Since margin of error is proportional with inverse of
,
if we cut the sample size in half, the margin of error is multiplied by
.
