Answer:
x = -20
Step-by-step explanation:
First we can rearrange the equation:
-18 = -28
2 * - 18 = -28 * 2
The 2s canel out
x - 36 = - 56
x = -20
2(p+w)=240
p+w=120
w=120-p, we will use this value for w below...
2(p-w)=210
p-w=105, now use the w from earlier...
p-120+p=105
2p-120=105
2p=225
p=112.5 mph (and wind is 7.5 mph)
Function 1 has a maximum at y = 1
Now we need to find the maximum of Function 2 by completing the square:
-x^2 + 2x - 3
= -(x^2 - 2x) - 3
= -(x - 1)^2 +1 - 3
= -(x - 1)^2 - 2
Therefor the turning point is at (1, -2) and the maximum is at y = -2
-2 < 1, therefor Function 1 has the larger maximum
Answer:
1 / 7
Step-by-step explanation:
Given the distribution above :
P(grade B or higher) can be defined explicitly as :
P(Grade A) + P(Grade B)
P(grade A) = 2/35
P(Grade B) = 3 / 35
Hence,
P(Grade B or higher) = 2/35 + 3/35 = 5/35 = 1/7
