Answer:
0.0475
Step-by-step explanation:
First find the z-score.
z = (x − μ) / σ
z = (125 − 100) / 15
z = 1.67
Use a calculator or chart to find the probability. Using a chart:
P(Z > 1.67) = 1 − P(Z < 1.67)
P(Z > 1.67) = 1 − 0.9525
P(Z > 1.67) = 0.0475
Answer:
x=15.73292
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
cos theta = adj/ hyp
cos 70 = x / 46
46 cos 70 =x
x=15.73292
You need to select two points on the line:
The rise is the vertical distance, and the run is the horizontal distance:
Rise: Use the coordinates in y to find the rise:

Run: Use the coordinates in x to find the run:

The slope (m) is: 1/2 or 0.5
Your answer would be:
Formula: I = P * r * t
P = Principle $5000
R = Rate 2.5% per year, or in decimal form, 2.5/100 =0.025
T = Time involved 7 years time period
I = Interest
Part A:
P = 5000
R = 2.5%, or .025
Part B: Riley To find the simple interest, we multiply
I = 5000 * 0.025 * 7
T = 7
The Interest is = $875.00
Part C: Investment Balance = Investment + Interest
Usually the interest is added onto the principal t figure out the new amount after 7 years.
= $5000.00 + $875
= $5875.00
Ex. if you borrowed $5000, you would now owed $5875.00
Hope that helps!!!
