Answer:
0
Step-by-step explanation:
To find the slope of two points, here is the formula (y2-y1)/(x2-x1)
So we have (1,2) and (4,2),
We let y2 = 2 and y1 = 2 and we let x2 = 4 and x1 = 1
So, (2-2)/(4-1) = 0/3
Our slope is 0.
Answer:
The 95% confidence interval for the population mean weight of newborn elephants is between 242.12 pounds and 245.88 pounds.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 244 - 1.88 = 242.12 pounds.
The upper end of the interval is the sample mean added to M. So it is 244 + 1.88 = 245.88 pounds
The 95% confidence interval for the population mean weight of newborn elephants is between 242.12 pounds and 245.88 pounds.
To find the measure of the smallest angle of the triangle, we multiply 4 times 10. So, 4 x 10 = 40. Remember, the sum of the angles of a triangle is 180 degrees. Just take what you are given in a problem and try to determine what will make the final angle add up to 180 degrees.
Answer:
160
Step-by-step explanation:
First Simplify the numbers we know. Therefore we get: x2=75/3 which is the same as x2=25
Now find the square root of 25, which is 5 or -5. Therefore x=5 or -5
