Answer:
$11.25
Step-by-step explanation:
You take the original cost and multiply it by 0.25 for 25%. You get 3.75. Then you subtract 3.75 from 15.00. The answer is $11.25
The probability is 0.7734.
The z-score for this value is given by:
z =(X-μ)/σ = (83-101)/24 = -18/24 = -0.75.
Using a z-table (http://www.z-table.com) we see that the area to the left of this (lower than) is 0.2266. We want the percentage that will score higher on the test, so we subtract fro 1:
1 - 0.2266 = 0.7734.
Answer:C
Step-by-step explanation:
trust meh
Answer:
C has a magnitud of 10.4 units and is directed 270° from the positive x-axis
Step-by-step explanation:
As it shows on the attached picture, the xA and xB have equal magnitudes but opposite directions, therefore they cancel eachother out in the x-axis.
However, the yA and yB are equal in magnitud, but have the same direction. So, the create a total vector the is completely on the y-axis and it's magnitude is 2*(sin(60°)*6)=10.4 units.
In order for C to cancel this vector, it's magnitude also needs to be 10.4 units, but pointing the other way. Therefore, the angle needs to be 270° from the positive x-axis.
Answer:
D
Step-by-step explanation:
to find the value in grams, we just multiply by a 1000
so, 31.8 × 1000 = 31,800 grams
