Answer:
The answer is 3/4 = 75%
Step-by-step explanation:
3/4 = 75%
It is: 3/4 = 75%
Answer:
95% Confidence interval for the variance:

95% Confidence interval for the standard deviation:

Step-by-step explanation:
We have to calculate a 95% confidence interval for the standard deviation σ and the variance σ².
The sample, of size n=8, has a standard deviation of s=2.89 miles.
Then, the variance of the sample is

The confidence interval for the variance is:

The critical values for the Chi-square distribution for a 95% confidence (α=0.05) interval are:

Then, the confidence interval can be calculated as:

If we calculate the square root for each bound we will have the confidence interval for the standard deviation:

So we already drew two cards and both of them are spades. So that means there are 50 cards and 11 spades left.
Then third card being spades would be 11 / 50
Now there are 10 spades and 49 cards left.
So the probability for fourth card would be 10 / 49
Fifth card would be 9 / 48.
So the probability of next three cards being spades would be

Hope this helps.
Answer:
Step-by-step explanation:
Compare any two points on same horizontal line.
<u>The easy one is:</u>
<u>Since g(x) = f(kx), substitute the x- coordinates to find the value of k:</u>
- - 1 = k*(-3)
- k = - 1/ - 3
- k = 1/3
Correct choice is B
The answer is 1 : 1 : square root of 3
