First you want to break down both numbers to prime factors so for 10 you would get 10=2x5 and 14 you would get 14=2x7 then you will want to take the greatest common factor of both which is 2 because it is the only factor that is shared between the two then you take the two beginning numbers and divide them by 2 because it is the greatest common factor and 5/7 is your anwser

Does anyone know the answers to these?

dem82 [27]

Step-by-step explanation:

a. The point estimate is the mean, 47 days.

b. The margin of error is the critical value times the standard error.

At 31 degrees of freedom and 98% confidence, t = 2.453.

The margin of error is therefore:

MoE = 2.453 × 10.2 / √32

MoE = 4.42

c. The confidence interval is:

CI = 47 ± 4.42

CI = (42.58, 51.42)

d. We can conclude with 98% confidence that the true mean is between 42.58 days and 51.42 days.

e. We can reduce the margin of error by either increasing the sample size, or using a lower confidence level.

How would I do this? What would it be?

Answer: $x=80$

Step-by-step explanation:

By definition, the sum of the exterior angles of a polygon is 360 degrees.

Knowing this, you can write the following equation:

$(x+8)+(2x+12)+(x+20)=360$

Then, you must solve for "x" in order to find its value. To do it, you can follow these steps:

1. You need to add the like terms:

$(x+8)+(2x+12)+(x+20)=360\\\\4x+40=360$

2. Now, subtract 40 from both sides of the equation:

$4x+40-(40)=360-(40)\\\\4x=320$

3. Finally, you must divide both sides of the equation by 4. Then:

$\frac{4x}{4}=\frac{320}{4}\\\\x=80$
