Answer:
Part A:
The probability that all of the balls selected are white:
Part B:
The conditional probability that the die landed on 3 if all the balls selected are white:
Step-by-step explanation:
A is the event all balls are white.
D_i is the dice outcome.
Sine the die is fair:
for i∈{1,2,3,4,5,6}
In case of 10 black and 5 white balls:
Part A:
The probability that all of the balls selected are white:
Part B:
The conditional probability that the die landed on 3 if all the balls selected are white:
We have to find
The data required is calculated above:
Answer:
Step-by-step explanation:
We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean
For the null hypothesis,
µ = 25235
For the alternative hypothesis,
µ > 25235
This is a right tailed test.
Since the population standard deviation is not given, the distribution is a student's t.
Since n = 100,
Degrees of freedom, df = n - 1 = 100 - 1 = 99
t = (x - µ)/(s/√n)
Where
x = sample mean = 27524
µ = population mean = 25235
s = samples standard deviation = 6000
t = (27524 - 25235)/(6000/√100) = 3.815
We would determine the p value using the t test calculator. It becomes
p = 0.000119
Since alpha, 0.05 > than the p value, 0.000119, then we would reject the null hypothesis. There is sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area.
Answer:74.55 beat per minute
Step-by-step explanation:
Given
Heart beat is 52 beat per minute
i.e. beat per sec
If heart rate is increases 1.25 % each sec
suppose B is the heart beat at first second therefore heat beat at 2 nd second
For 3 rd sec
similarly for 3 sec
For ΔABD, it is given that side AB is congruent to side CB, that ∠ABD is congruent to ∠CBD. In order to invoke the SAS Postulate, the remaining side(s) fo the triangles must be shown to be congruent. Those sides are BD and BD.
The appropriate choice is ...
... b. BD ≅ BD
