Answer:

1. 5 miles

2. 5 4/12 cups

3. 9/16 gallons

4. 45.7 km/h

5. 18.7 m/h

Step-by-step explanation:

For the first one, she jogs 1/2 miles in 1/10 of an hour. So to get an hour you can do the reciprocal of 1/10 to get 1

1/10 * 10/1 = 1 hour

Now you have to do that to the miles as well.

1/2 * 10/1

1 * 10 = 10

2 * 1 = 2

10/2

5 miles

So she jogged 5 miles in 1 hour

For the second one, 8 3/4 cups of milk for 3 1/3 cups of cereal. You need 1 cup though.

So to find 1 cup you have to get a common denominator first.

1/3

3/4

A common factor is 12. multiply 4 for both the top and the bottom for 1/3 and 3 to top and bottom for 3/4. What's done to the top must be done to the bottom as well.

1/3 *4/4 = 4/12

3/4 * 3/3 = 9/12

8 4/12 and 3 9/12 is what you have now.

You only need 1 cup so you can subtract 2 9/12 to both.

8 4/12 - 2 9/12 = 5 4/12

3 9/12 - 2 9/12 = 1

So 1 cup of oatmeal uses 5 4/12 cups of milk.

For the third one, 3/16 gallons of water for 1/3 feet of garden.

You need to find that for 1 foot so it be similar to the first one.

Use reciprocal on 1/3 to get that 1 foot you need.

1/3 * 3/1 = 1

What you do to one you have to do to the other.

3/16 * 3/1 = 9/16

You can't simplify it so that's its simplest form.

S 1 foot of garden uses 9/16 gallons of water.

Numero four. This one seems hard but really all you have to do is divide km by h.

822.6 km/ 18 h

45.7 km/h

Last one, once again all you have to do is divide m by h to get m/h.

768.57m/41.1h

18.7 m/h

And thats it! I hope this helps you and if you ever need any more help, don't be afraid to reach out.

Complete question

The number of absences per student in each of two classes is shown on the dot plots below.

A dot plot titled Number of absences per student in Misses Anderson's class. The number line goes from 0 to 6. There is 1 dot above 0, 3 above 1, 3 above 2, 3 above 3, 1 above 4, and 0 above 5 and 6.

A dot plot titled Number of absences per student in Misses Bergot's class. The number line goes from 0 to 6. There is 1 dot above 0, 1 above 1, 2 above 2, 3 above 3, 2 above 4, 1 above 5, and 1 above 6.

Which statements accurately compare the two data sets? Select three options.

a. The mean number of absences is greater in Mrs. Anderson’s class.

b. The mean number of absences is greater in Mrs. Bergot’s class.

c. There is more variability in Mrs. Anderson’s data set.

d. There is more variability in Mrs. Bergot’s data set.

e. The mean and MAD are better representations of these data sets than the median and IQR.

Answer:

b. The mean number of absences is greater in Mrs. Bergot’s class.

d. There is more variability in Mrs. Bergot’s data set.

e. The mean and MAD are better representations of these data sets than the median and IQR.

Step-by-step explanation:

From the above data given in the question and the options given to us, we can observe from the comparison of both the number of absences in Mrs Bergot's class to that in Mrs Anderson's class, there will be a presence of variation in the data of one of the classes and that class happens to be Mrs Bergot's class.

The appropriate statistical tool that we can be used to determine and measure the centre of variability of the data is Mean and Mean Absolute Deviation.

Which is irrational?
sladkih [1.3K]

Answer:

  (b)  √5

Step-by-step explanation:

The square root of an integer is rational if the integer is a perfect square. You probably know the first few perfect square integers are 1, 4, 9, 16, 25, 36, ...

The integer 5 is not on that list, so its square root will be irrational.

  √5 is irrational
