Answers

Answer:

The answer is c

Step-by-step explanation:

The middle line is in the same spot

The boxplot that could represent this data is boxplot B.

What is the interquartile range?

An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.

W can find the values of the upper and lower quartile and median from a box plot.

The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.

The formula used is Upper quartile - Lower quartile.

We have,

Ramon drew boxplots to summarize the number of pages in each chapter of two books.

The value of the interquartile ranges of these boxplots is the same.

So,

We see that,

Box plot B has the same interquartile range.

i.e

35 - 20 = 15

30 - 15 = 15

This is the only boxplot that has the same interquartile ranges.

Thus,

Box plot B has the same interquartile range.

Can someone please help me find the measure of the exterior angle.

Answers

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180° because they are supplementary angles

k = 140°

Answer:

k = 140°

Step-by-step explanation:

The sum of the interior angles of any triangle = 180°.

64° + 76° + x = 180°

x = 40°

40° + k = 180°

k = 140°

Answer:

Step-by-step explanation:

Income: 600,000 + 600,000 + 400,000 =

$1,600,000

Expenses: 400,000 + 500,000 + 600,000 =

$1,500,000

B .

Expenses: 600,000 + 700,000 =

$1,300,000

Income: 400,000 + 600,000 =

$1,000,000

1,300,000 - 1,000,000 = $300,000

Expenses:

Year 1: 400,000

+ 100,000 =

Year 2: 500,000

+ 100,000 =

Year 3: 600,000

+ 100,000 =

Year 4: 700,000

+ 100,000 =

Year 5: 800, 000

Adds 100,000 each year not 200,000.

Income:

Year 1: 600,000 x 2 =

$1,200,000

Year 5:

$900,000

Answer:

The combined expenses in Years 3 and 4 were $300,000 more than the combined income of Years 3 and 4.

Step-by-step explanation:

The combined income in years 1, 2, and 3 is $1,400,000 and the combined expenses in the same years is $1,500,000; so number 1 is incorrect.

Expenses have increased $100,000 each year over the last 5 years. Year 1 = $400,000 , Year 2 = $500,000 , Year 3 = $600,000 , Year 4 = $700,000 , Year 5 = $800,000. So number 3 is incorrect.

Year 1's income was $600,000 and Year 5's income was $900,000. Twice Year 1's income would have been $1,200,000. So number 4 is incorrect.

The molecules in the rods and cones in the eye are turned to absorb photons of particular energies. The retinal molecule, like many molecules, is a long chain. Electrons can freely move along one stretch of the chain but are reflected at the ends, thus behaving like a particle in a one-dimensional box. The absorption of a photon lifts an electron from the ground state into the first excited state.
