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: 0.8% of 5,700 = <u><em>45.6 </em></u>
Step-by-step explanation:
0.8% × 5,700 =
(0.8 ÷ 100) × 5,700 =
(0.8 × 5,700) ÷ 100 =
4,560 ÷ 100 =
45.6;
Given 460 
a) convert it into 
=> It means 
and 
1 ft = 0.3048 m
1 gal = 3.78541 l
![460ft^2= [tex]460\frac{ft^2}{gal} = \frac{42.7354m^2}{3.78541l} = 11.2895m^2/l](https://tex.z-dn.net/?f=460ft%5E2%3D%20%5Btex%5D460%5Cfrac%7Bft%5E2%7D%7Bgal%7D%20%3D%20%5Cfrac%7B42.7354m%5E2%7D%7B3.78541l%7D%20%3D%2011.2895m%5E2%2Fl)

Answer:
or 
Step-by-step explanation:
first use the y2-y1/x2-x1 formula then use y=mx+b after
plug in 2 for y2 and -1 for y1
plug in -5 for x2 and 5 for x1
=
2+1=3
-5-5=-10
is ur slope
_____________________
this is the y=mx+b formula *extra info ig*
i usually use the first point for this but u can use watever point u want
plug in 5 for x
plug in -1 for y
and plug -3/10 for m
-1=-3/10(5)+b
-3/10*5=-3/2
-1=-3/2+b
add -3/2 on both sides
-1+3/2=1/2
1/2=b and b is ur y-intercept
y=-3/10x+1/2
hope this helps
