Answer:
The radius is 7
The diameter is 14
The circumference is 43.98 (if they want it simplified put 44)
Step-by-step explanation:
1.The radius is already given in the picture so the answer is 7
2.To find the diameter, multiply the radius by two. 7 times 2=14
3.The formula for circumference is C=2r. Remove the r and replace it with the number 7. Plug 2
7 into your calculator and you will get 43.98
Answer:
Step-by-step explanation:
We need to write the equation in slope-intercept form which passes through points (1/5,-4) and (16/5,-9)
Slope is given formula:
Now plug the value of slope m and any one of the given point into point slope formula:
Now simplify this and write in slope intercept form y=mx=b
Hence final answer is
Answer:
The probability that the page will get at least one hit during any given minute is 0.9093.
Step-by-step explanation:
Let <em>X</em> = number of hits a web page receives per minute.
The random variable <em>X</em> follows a Poisson distribution with parameter,
<em>λ</em> = 2.4.
The probability function of a Poisson distribution is:
Compute the probability that the page will get at least one hit during any given minute as follows:
P (X ≥ 1) = 1 - P (X < 1)
= 1 - P (X = 0)
Thus, the probability that the page will get at least one hit during any given minute is 0.9093.
Answer:
A normal distribution or z-test is used to construct a confidence interval.
Step-by-step explanation:
We are given the following in the question:
Sample mean, = $3120
Sample size, n = 40
Population standard deviation, σ = $677
The distribution of earnings of college is a normal distribution.
Conditions:
Conclusion:
Thus, we use a normal distribution or z-test to construct a confidence interval.
