Answer:

For knowing what the probability will be, you need to see the dice individually.

The probability that dice 1 will get a 1, is 1/6.

The probability that dice 2 will get an odd number, is 3/6 or 1/2.

Now what is the probability that those two both come true?

I have no clue maybe multiply both and then you will get something like;

1/6.1/2 = 1/12

Whats the coefficient <br>x - 7y + 8

s2008m [1.1K]

Answer:

-7

Step-by-step explanation:

-7 is the number that is attached to the y. It is the coefficient. Another possible coefficient is 1, but you do not need to write it, as anything multiplied by 1 is equal to the original number.

Hope this was helpful! Let me know if you have any further questions. :)

stat crunch A simple random sample of size n=250 individuals who are currently employed is asked if they work at home at least o

Masteriza [31]

Answer:

The 99% confidence interval for the population proportion of employed individuals who work at home at least once per week is between (0.104, 0.224).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 250, \pi = \frac{41}{250} = 0.164$

99% confidence level

So $\alpha = 0.01$ , z is the value of Z that has a pvalue of $1 - \frac{0.01}{2} = 0.995$ , so $Z = 2.575$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.164 - 2.575\sqrt{\frac{0.164*0.836}{250}} = 0.104$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.164 + 2.575\sqrt{\frac{0.164*0.836}{250}} = 0.224$

The 99% confidence interval for the population proportion of employed individuals who work at home at least once per week is between (0.104, 0.224).

A cone has a volume of 602.88 cubic centimeters and a radius of 6 centimeters. What is its height? Use ≈ 3.14 and round your a

meriva

Answer:

15.98cm

Step-by-step explanation:

Given data

Volume= 602.88cm^3

Radius= 6cm

The formula for the volume of a cone is

V= 1/3 πr^2h

substitute

602.88= 1/3*3.142*6^2*h

602.88=1/3*3.142*36*h

602.88=37.704*h

h= 602.88/37.704

h= 15.98cm

Hence the height is 15.98cm
