One astronomical unit is about 93,000,000 miles. At 20,000 miles per hour how many astronomical units can Orion travel? ( Orion

uranmaximum [27]

Answer:

$2.15\times 10^{-4}\ AU$

Step-by-step explanation:

Given that:-

The speed of the orion= 20,000 miles per hour

Time = 1 hour ( From source )

Thus,

Distance = Speed * Time = 20,000*1 miles = 20,000 miles

Thus, in 1 hour, the orion can travel 20,000 miles

Also,

93,000,000 miles = 1 astronomical unit

1 mile = 1/93,000,000 astronomical unit

20,000 miles = (1/93,000,000)*20,000 astronomical unit

The orion can travel $2.15\times 10^{-4}$ AU in one hour.

What is the average rate of change for this function for the interval from x=3 to x=5?

timofeeve [1]

Answer:

B

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ 3, 5 ]

From the table of values

f(b) = f(5) = 32

f(a) = f(3) = 8

Hence

average rate of change = $\frac{32-8}{5-3}$ = $\frac{24}{2}$ = 12

What is meant by the term outlier? What should you do with an outlier?

saul85 [17]

Outliers are data that are in a very far distance from other values in a set of data

Once an outlier is detected in a set of data, we can do the following to them:

Discard the outlier
Change the value of the outlier with another value within close range
Consider the distribution given

We may have a set of data where some of the values are far in distance from the majority of the data. The set of such data are known as an outlier.

For example, give the set of data;

2, 4, 7, 45, 8

45 can be considered as an outlier since the distance of data to all other data is large.

Once an outlier is detected in a set of data, we can do the following to them:

Discard the outlier
Change the value of the outlier with another value within close range
Consider the distribution given

What is the area of this shape?

Elena L [17]

Answer:

12mm (triangle)

165mm (whole shape)

Step-by-step explanation:

The triangle is 6 x 4 = 24 ÷ 2= 12

(divide by 2 because its a teiangle)

2nd shape is 10 x 8 = 80

3rd shape is 6 x 12 = 72

72 + 80 + 12 = 165mm
