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:
31.5 quarts
Step-by-step explanation:
5x7=35
35pints=17.5quarts
8x7=56
56cups=14quarts
17.5+14=31.5quarts
Here it is…
Simplifying
C = 25h + 50
Reorder the terms:
C = 50 + 25h
Solving
C = 50 + 25h
Solving for variable 'C'.
Move all terms containing C to the left, all other terms to the right.
Simplifying
C = 50 + 25h
The equation is y=-2x^2+6
