Answer:
12
Step-by-step explanation:
So we use PEMDAS:
-5 + 8 = 3
3 + 9 = 12
So take 13, 8 and 4 and add those together to get the budget she needs for the month.
13+8+4=25
so she needs $25 in all, to find how much more than 16 she needs you take 25 and minus 16 from it.
25-16=19
so she needs $19 more to have a balanced budget.
You subtract the known angle measurements from 180 because a straight line means the whole undivided angle is 180 degrees and the answer to the subtraction is your missing angle measurement

Answer: 0.9927
Step-by-step explanation:
We assume that the number of earthquakes that occur in Los Angeles follows normal distribution.
As per given , we have

Sample size : n= 35
Let
be the sample mean.
Now ,

Hence, the probability that the mean of the sample is between 34 and 37.5. is 0.9927 .
Answer:
Slope: 1
Y-intercept: (0,3)
Step-by-step explanation:
The y intercept is when the slope reaches the y-axis line. In this case, it is given to us. Anything that is formed like this: (0, y) is the y-intercept.
Y intercept: (0, 3)
For slope, you can use the formula rise over run. 
From the picture, I have drawn the rise over run, which is
, which is also 1.
Slope: 1
