If function f is a cubic polynomial which statement most accurately describes the function over the interview (0,1)
inysia [295]

Answer:

Option (B)

Step-by-step explanation:

From the given table,

With the increase in the values of x (from x = -2 to x = 2), values of the function is decreasing from x =2 to x = 4.

Interval (0, 1) lies in the domain of the function in which the y-values of the function are,

At x = 0,

f(0) = -6

At x = 1,

f(1) = 0

Therefore, values of the given function are increasing in the interval of (0, 1).

Option (B) will be the correct option.

You live 3.67 miles from your grandparents and you are biking how do you solve this
ipn [44]
To solve for revolutions, we will have to take the distance of the travel and divide that by the circumference of the wheel.

Distance of travel = 3.67 miles
Circumference of wheel = 82.6 inches

We have to convert the inches to miles. There are 63360 inches in one mile.

Circumference of wheel = 82.6 in * (1 mi/63360 in) = 0.0013 miles

Revolutions = Distance/Circumference = 63,538.46 revolutions

"In a mid-size company, the distribution of the number of phone calls answered each day by each of the 12 receptionists is bell-
creativ13 [48]

Answer:

For this case we want to find this probability:

P(10

And we can use the z score formula to see how many deviation we are within the mean and we got:

z = \frac{10-37}{9}=-3

z = \frac{64-37}{9}=3

And for this case we know that within 3 deviation from the mean we have 99.7% of the values and that's the answer for this case.

Step-by-step explanation:

Previous concepts

The empirical rule, also known as three-sigma rule or 68-95-99.7 rule, "is a statistical rule which states that for a normal distribution, almost all data falls within three standard deviations (denoted by σ) of the mean (denoted by µ)".

Let X the random variable who represent the number of phone calls answered.

From the problem we have the mean and the standard deviation for the random variable X. E(X)=37, Sd(X)=9

So we can assume \mu=37 , \sigma=9

On this case in order to check if the random variable X follows a normal distribution we can use the empirical rule that states the following:

• The probability of obtain values within one deviation from the mean is 0.68

• The probability of obtain values within two deviation's from the mean is 0.95

• The probability of obtain values within three deviation's from the mean is 0.997

Solution to the problem

For this case we want to find this probability:

P(10

And we can use the z score formula to see how many deviation we are within the mean and we got:

z = \frac{10-37}{9}=-3

z = \frac{64-37}{9}=3

And for this case we know that within 3 deviation from the mean we have 99.7% of the values and that's the answer for this case.
