Answer:
<h2>8 times greater</h2>
Step-by-step explanation:
The formula of a volume of a cube:

a - edge length
-----------------------------------
The edge length of cube B is a.
The edge length of cube A is 2a.
Calculate the volumes:

How many times greater is the volume of the cube A than the volume of cube B?
Make the quotient:

Using the normal distribution, it is found that there is a 0.877 = 87.7% probability of a bulb lasting for at most 569 hours.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:

The probability of a bulb lasting for at most 569 hours is the <u>p-value of Z when X = 569</u>, hence:


Z = 1.16
Z = 1.16 has a p-value of 0.877.
0.877 = 87.7% probability of a bulb lasting for at most 569 hours.

just add 6.4 and 9.8 you will get 16.2 miles
We need to convert the equation of the circle to standard form only then we can find the radius and the center of the circle.

From this equation we can write:
Center of the circle is (-1,1) and the radius of the circle is 4.
