Answer:
Step-by-step explanation:
Let the probability of getting employed after graduated within a year be P(A)
and the probability of buying a car within a year be P(B)
Given that:
The probability of getting employed after graduated within a year = 90% = 0.9
Then; Let that be P(A)
The probability of getting employed and buying a car within a year = 72% = 0.72.
Then; Let that be P(A∩ B).
The probability that a college student will get both events is P(B/A)
P(B/A) = 0.80
Answer:
There is difference in the scores of males and females
Step-by-step explanation:
Given that a professor teaches a certain section of material using a lot of examples with sports and cars to illustrate. He is concerned that this may have biased his instruction to favor male students
Since simple variances are unequal, we can do t test for comparison of two means with unequal variances
Group Group One Group Two
Mean 84.00 78.00
SD 4.00 8.00
SEM 1.26 2.53
N 10 10
The mean of Group One minus Group Two equals 6.00
95% confidence interval of this difference: From 0.06 to 11.94
t = 2.1213
df = 18
standard error of difference = 2.828
The two-tailed P value equals 0.0480
Since p <0.05 we reject null hypothesis
There is difference in the scores of males and females
Answer is dilation and then reflection
Step-by-step explanation: It goes down at first so that dilation then it reflects to C.
The diameter is = (4/3)(pi)(d/2)(d/2) = (4/3)(pi)(16) = pi*64/3
