Answer:
Ratio
Step-by-step explanation:
First lets understand various scales of measurement in psychology
- Nominal: Separate numbers indicate separate objects. these no actual meaning other than separating between objects.
example: number on vests of football players
2.Ordinal: meaning order
example: place finished in a race 1st , 2nd
3. Interval: have no order
equal interval between the adjacent categories
the difference between two similar physical quantity is same
4. Ratio: Differences are meaningful like interval
ratios are meaningful , Existence of "true zero point"
Now in the above case money is spend to buy candies which is meaningful and if no money is spent no candies are purchased hence existence of "True zero point"
Hence Ratio scale would be most appropriate to measure this case
The correct answer for the question that is being presented above is this one: "A. (3/8)." According to the general equation for conditional probability <span>if P(AupsidedownuB) = (3/10) and P(B)= (2/5), then P(A|B) is 3/8.</span>
Here are the following choices:
<span>A. (3/8)
B. (1/2)
C. (3/4)
D. (1/16)</span>
Answer:
7/25
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
Probability = expected outcome/total outcome
If the box contains 3 black pens, 7 blue pens, and 5 red pens, the total number of pens in the box is 3+7+5 = 15pens
Probability of pulling a red pen and replacing = 5/15 = 1/3
Probability of pulling a blue pen and replacing = 7/15
Probability of pulling a black pen and not replacing(using it) = 3/15
{Note that the total number of outcome used will still be 15 since the black pen was pulled out last even though it wasn't replaced.}
P(red, then blue, then black) = 1/3×7/15×3/15
= 63/225
= 7/25
Answer:
D.30,40,50
Step-by-step explanation:
A.4,5,6
B.2,3,4
C.10,20,30
D.30,40,50
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
4² + 5² = 25 is not equal to the square of 6 which is 36
2² + 3² = 10 . 10 is not equal to the square of 4 which is 16
10² + 20³ = 500. 500 is not equal to the square of 30 which is 900
30² + 40² = 2500. this is equal to the square of 50
X
38 -> 24x
x > 38 -> 31(x-38) + 912
912 = 24*38 (You will have to have 38 hours to be able to be in this part of the piece wise function)
