Answer 1

Answer: You input the values and the equation would end up as

-5 = -3/2 (6) + b

You use y = mx + b

Y is -5
M is the slope = -3/2
X is 6
B is the y intercept but that is not given

Answer:

23.59 - 14.89 = x

x = 8.7

Step-by-step explanation:

To find x, you need to add all of the other sides and subtract it from the perimeter. 5.62 + 5.62 + 3.65 = 14.89.

23.59 - 14.89 = x, so x = 8.7

Answer:

8.7

Step-by-step explanation:

Add all the numbers together (5.62, 5.62, and 3.65) then take away from the result (23.59) to get answer.

Trick or treaters arrive to your house according to a Poisson process with a constant rate parameter of 20 per hour. Suppose you begin sitting on your front porch, observing these arrivals, at some point in time. Suppose a trick or treater arrived 30 minutes ago, but there have been none since. What is the expected value of interarrival time (in minutes) from the previous trick or treater to the next one

Answers

Answer:

The expected value of interarrival time (in minutes) from the previous trick or treater to the next one is 3 minutes.

Step-by-step explanation:

We have a Poisson process with a constant rate parameter of 20 arrival per hour.

This type of processes are memory-less, meaning that no matter how much time has passed form the last event, the probabilities of an arrival stay the same.

The mean interarrival time can be calculated as the inverse of the mean arrival for the Poisson process.

If the Poisson process has a rate of 20 arrivals per hour, the mean interarrival time is:

$\bar t=1/\lambda=1/20=0.05\,h/arrival=3 \,min/arrival$

In a clinical trial of 2165 subjects treated with a certain drug, 21 reported headaches. In a control group of 1718 subjects given a placebo, 23 reported headaches. Denoting the proportion of headaches in the treatment group by pt and denoting the proportion of headaches in the control (placebo) group by pc, the relative risk is pt/pc. The relative risk is a measure of the strength of the effect of the drug treatment. Another such measure is the odds ratio, which is the ratio of the odds in favor of a headache for the treatment group to the odds in favor of a headache for the control (placebo) group, found by evaluating StartFraction p Subscript t Baseline divided by (1 minus p Subscript t Baseline )Over p Subscript c Baseline divided by (1 minus p Subscript c Baseline )EndFraction . The relative risk and odds ratios are commonly used in medicine and epidemiological studies. Find the relative risk and odds ratio for the headache data. What do the results suggest about the risk of a headache from the drug treatment?

What is the reciprocal of 7 1/3? whats the reciprocal?

Answers

The reciprocal of a number in mathematics is referred to as the inverse of that number.

This means that:

Given a number x, its reciprocal is :

$x = x/ 1= 1/x$

Given a number 1/x, its reciprocal is

$1/x = x/1$

The reciprocal of $7(1)/(3)$ is $(3)/(22)$

From the question, $7(1)/(3)$ is called a mixed fraction

Converting to an improper fraction

$7(1)/(3)$ = $(22)/(3)$

The inverse of $(22)/(3)$

$(22)/(3)$ = $(3)/(22)$

Therefore, the reciprocal of $7(1)/(3)$ is $(3)/(22)$

Answer:

3/22

Step-by-step explanation:

Reciprocal means the inverse of the fraction. For your mixed number 7 and 1/3, turn it into fraction by multiplying 7 with the denominator which is 3, then add the numerator which is 1 to get the numerator of a normal fraction which is 22. The numerator remains the same.

The fraction is 22/3. As mentioned above, reciprocal means the inverse, so the final answer is 3/22
