Answer:

c. 2/3

Step-by-step explanation:

To find the slope, you subtract y^1 from y^2 and divide it by x^2 - x^1

Our y^2 is 7 and our y^1 is 1.

7-1 = 6

Our x^2 is 3 and our x^1 is -6.

3 - (-6) = 3+ 6 = 9

so our slope is 6/9, reduced is 2/3

I hope this helped, please mark Brainliest, thank you!!

Find the median, Q1, Q3, interquartile range (IQR), and list any outliers. 2) 74, 63, 69, 62, 33, 79, 70, 60, 107, 119

e-lub [12.9K]

Answer:

Since the sample size is n=10 we can find the first quartile taking in count the first 5 observations from the data set ordered and we have this:

33 60 62 63 69

$Q_1 =62$

We can find the third quartile taking in count the last 5 observations from the data set ordered and we have this:

70 74 79 107 119

$Q_3 =79$

And finally the median can be calculated with the average of the two moddlie values and we got:

$Median= \frac{69+70}{2} =69.5$

And the IQr would be:

$IQR = 79-62= 17$

Step-by-step explanation:

Assuming that 2 is not part of the data we have:

74, 63, 69, 62, 33, 79, 70, 60, 107, 119

We can sort the values on increasing order and we got:

33 60 62 63 69 70 74 79 107 119

Since the sample size is n=10 we can find the first quartile taking in count the first 5 observations from the data set ordered and we have this:

33 60 62 63 69

$Q_1 =62$

We can find the third quartile taking in count the last 5 observations from the data set ordered and we have this:

70 74 79 107 119

$Q_3 =79$

And finally the median can be calculated with the average of the two moddlie values and we got:

$Median= \frac{69+70}{2} =69.5$

And the IQr would be:

$IQR = 79-62= 17$

Jill’s teacher asked her to construct a rectangular prism from unit cubes. She has built the structure about. In order for Jill

malfutka [58]

Answer:

36 cubes
There are several forms to figure it out: see two different ways explained below.

Explanation:

The first way to figure out how many more cubes Jill will need to add to complete the structure until forming a rectangular prism is to add the cubes from column to colum,

The first column is complete: it has four rows each with 4 cubes.

The second column (the one next to the right of the first column) has three rows. Then Jill has to add one more row. This is 4 cubes.

The third column has two rows. Then, Jill will need to add two rows with 4 cubes each, for a total of 8 cubes. So far, the count is 4 + 8 = 12 cubes.

The fourth and fifth columns have just one row. Then, Jill will need 3 rows for each column, making it 2 × 3 × 4 = 24 cubes.

The total final count is 12 + 24 = 36 cubes. ← answer

There are different ways to figure out the number of cubes needed to complete the rectangular prism. This is another one:

How many cubes shall the complete pyramid have? : 4 × 4 × 5 = 80 (length × width × height).

How many cubes does the shown incomplete structure have?: 4×4 + 3×4 + 2×4 + 4 + 4 = 16 + 12 + 8 + 4 + 4 = 44.

Difference: 80 - 44 = 36 cubes. ← answer

(-64)^(1/2) evaluated?

bazaltina [42]

Answer:

Step-by-step explanation:

When a quantity is raised to a fractional power, you need to root it to the power of the denominator.

For example, (-64)^(1/2) = √(-64) 

Since you are taking the root of a negative, you will need to put an i (imaginary) in your answer.
