Answer:
The value for the test statistics = 3.48
Step-by-step explanation:
Given that:
population mean = 75
sample size n = 25
sample mean = 78.48
standard deviation = 5
The value for the test statistics can be computed by using the formula:
z = 3.48
The value for the test statistics = 3.48
1. Given that we have 4 green marbles, 4 pink marbles and 5 orange marbles, let us first find the probability that we select a pink marble.
We can find this by taking the number of pink marbles and dividing it by the total number of marbles:
Pr(P) = 4/(4 + 4 + 5)
= 4/13
2. Now that we have chosen one pink marble, we must find the probability that we choose an orange marble from the remaining marbles (4 green, 3 pink, 5 orange):
Pr(O) = 5/(4 + 3 + 5)
= 5/12
3. If we want to find the probability of picking a pink marble and then an orange marble, we must multiply the probabilities we have found in the first two steps:
Pr(P)*Pr(O) = (4/13)*(5/12)
= 20/156
= 5/39
Therefor, there is a probability of 5/39 that you pick a pink and then an orange marble.
Hello there!
First of all, find the slope of the right side of the graph. The slope is 2. So far we have:
y=2
Now look at the x coordinate of the point. Now we have:
y=2|x-0|
y=2|x|
Next the graph is shifted down 2 so add a negative two.
y=2|x|-2
I hope this helps!
Best wishes.
