Answer:
Step-by-step explanation:
<u>Use slope formula:</u>
1) Points (1, 2) and (5, 4)
- m = (4 - 2)/(5 - 1) = 2/4 = 1/2
2) Points (1, -5) and (3, 5)
- m = (5 - (-5))/(3 - 1) = 10/2 = 5
3) Points (2, 3) and (-1, 6)
- m = (6 - 3)/(-1 - 2) = 3/-3 = -1
- Slope is negative, so function is decreasing
4) Points (4, 2) and (-2, 2)
- m = (2 - 2)/(-2-4) = 0/-6 = 0
I = Prt
$192 = P*.016*3
$192/.048 = P = $4000
Bert should deposit $4000 to reach his interest goal.
Answer:
3i √3
Step-by-step explanation:
you can't have the square root of a negative number
so we use "i"
Answer:
0.41
Step-by-step explanation:
Given the data:
Subject Hours of Sleep
Subject 1 6
Subject 2 6.5
Subject 3 6
Subject 4 7.5
Subject 5 5
The standard error of the sample mean :(S. E) is given by standard deviation / square root of sample size.
To calculate the standard deviation :
Using the formula :
Sample size = n = 5
Sqrt(Σ(X - mean)^2 / n - 1)
This can be obtained faster using a calculator :
Hence, using calculator the standard deviation of the sample is 0.90829
Hence,
Standard Error = 0.90829 / sqrt(5)
Standard Error = 0.90829 / 2.2360679
Standard Error = 0.4061996
Answer:
$40.34
Step-by-step explanation:
x+(x+.91)=81.59
2x+.91=81.59
2x=80.68
x=40.34
