F(4) = 2(4)^3 -5
= 2(64) -5
= 128-5
= 123
Hope this helps!
Answer:
4x°= 4x18= 72°=measure of angle SQR
Step-by-step explanation:
6x +4x = 180
10x = 180
x = 180/10
x= 18°
because m L SQR =4x°
now place the value of x in the above equation
m L SQR = 4 x(18°)= 72°
Answer:
Step-by-step explanation:
Assuming there is a punitive removal of one point for an incorrect response.
Five undiscernable choices: 20% chance of guessing correctly -- Expectation: 0.20*(1) + 0.80*(-1) = -0.60
Four undiscernable choices: 25% chance of guessing correctly -- Expectation: 0.25*(1) + 0.75*(-1) = -0.50
I'll use 0.33 as an approzimation for 1/3
Three undiscernable choices: 33% chance of guessing correctly -- Expectation: 0.33*(1) + 0.67*(-1) = -0.33 <== The approximation is a little ugly.
Two undiscernable choices: 50% chance of guessing correctly -- Expectation: 0.50*(1) + 0.50*(-1) = 0.00
And thus we see that only if you can remove three is guessing neutral. There is no time when guessing is advantageous.
One Correct Answer: 100% chance of guessing correctly -- Expectation: 1.00*(1) + 0.00*(-1) = 1.00
Answer:
1) b=-1.6 2) g=3 3) x=0.8 4) w=4.9 5) p=-16.2 6) y=9.2
Step-by-step explanation:
Use inverese operations to isolate variables ex. x+4=2
x times 2 = 6 -4
/2 x=-2
x=3
