Answer:
See Below
Step-by-step explanation:
We are given 3 equations.
3x + 8
5x - 20
and
5x + 4y
First lets solve for x using the first two
3x + 8 = 5x -20
Move the variables to one side
3x + 8 = 5x -20
-3x -3x
8 = 2x -20
+20 +20
28 =2x
28/2 =2x /2
14 = x
Now we have x = 14
Lets plug this into the second equation to solve for the angle
3(14) + 8
42 + 8 = 50
5(14) - 20
70 - 20 =50
Now, lets plug the x and the angle into the third equation to find y
5 (14) +4y = 50
70 + 4y = 50
-70 -70
4y = -20
4y/4 = -20/4
y = -5
So now we have:
x = 14
y = -5
and the angle = 50
Hope this helps!

Answer with explanation:</h2>
The confidence interval for population mean is given by :-
Given : Sample size : n=106
Sample mean : 
Standard deviation : 
Significance level : 
Critical value : 
Then , 99% confidence interval estimate of the mean body temperature of all healthy humans will be :-
Since 98.6 is higher than the upper limit of the confidence interval (98.473), then this suggest that the mean body temperature could be lower then 98.6 degrees.
The best estimate of population mean is always the sample mean. 
Answer:
1101 base 2
Step-by-step explanation:
you first take the larger number up the the lower number down
- 11010 -1101
- when dividing if it's zero you borrow one from the number on the left hand side
- since it's in base 2 the number you borrow would be 2 then u subtract
- I hoped it helped u
