Answer:
The last one
Step-by-step explanation:
Because 0 < -2 -2, 0 <-4. It is not a true statement. It tell you that the middle one is wrong. The first one is wrong to because there are no equal sign.
It's C because you need to find how many points each student earned per grade (freshman & sophomore). Then you multiply it by 30 to find out how many points each student scored in the whole class.
Hope this helps!
Answer:
True
Step-by-step explanation:
Using a random chance procedure to assign subjects to treatment or control reduces bias. d. In a blind experiment, the subjects do not know whether they are in the treatment group or control group.
Answer:
The probability of eating pizza given that a new car is bought is 0.952
Step-by-step explanation:
This kind of problem can be solved using Baye’s theorem of conditional probability.
Let A be the event of eating pizza( same as buying pizza)
while B is the event of buying a new car
P(A) = 34% = 0.34
P(B) = 15% = 15/100 = 0.15
P(B|A) = 42% = 0.42
P(B|A) = P(BnA)/P(A)
0.42 = P(BnA)/0.34
P(B n A) = 0.34 * 0.42 = 0.1428
Now, we want to calculate P(A|B)
Mathematically;
P(A|B = P(A n B)/P(B)
Kindly know that P(A n B) = P(B n A) = 0.1428
So P(A|B) = 0.1428/0.15
P(A|B) = 0.952
