creativ13 [48]

Answer:

50 deciliters

Step-by-step explanation:

Given that,

Jennifer buys a 2-liter bottle of apple juice and a 3-liter bottle of orange juice at the market.

Total = 2 L bottle of apple juice + 3 L bottle of orange juice

= 5 L

We need to find how many deciliters of juice does Jennifer buy in all.

5 L = 50 Deciliter

So, she will buy 50 deciliters of juice.

Determine whether or not the following question can be considered as a statistical question.

Naddika [18.5K]

The situation would come as follows: "Does Andrew make more money than Laura?"

The question can only be answered with a yes or no. Which does not generate any statistics because they are characterized by having an inherent variability in the data used to answer the question. And in this question there is no variability since if you earn more money or not because they are focused on itself, there is a positive or negative side and from there there is no variation.

Therefore NOT a statistical question.

What's the round tens of 14,249?

grin007 [14]

Rounding a number means to change its value slightly so it is not as exact as the original number. Numbers are rounded to a certain place value - tens, hundreds, thousands. etc..

Numbers are rounded to make it easier to do various math processes such as estimating costs in one's head or dividing larger numbers.

RULE: To round a two digit number or higher number to the nearest tens place:

If the number in the ones place of a two digit number is less than five, round the number down to the nearest tens place. If the number in the ones place is greater than five, round it up to the nearest tens plac.

Example 1: Round 23 to the nearest tens place

The number 3 in the ones place is less than five. Therefore the number 23 is rounded down to 20.
23 rounded to the nearest tens place is 20.

Example 2: Round 28 to the nearest tens place.

The number 8 in the ones place is greater than five. Therefore the number 28 is rounded up to 30.
28 rounded to the nearest tens place is 30.

Example 3: Round 94 to the nearest tens place.

The number 4 in ones place is less than five. Therefore the number 94 is rounded down to 90.
94 rounded to the nearest tens place is 90.

Example 4: Round the number 97 to the nearest tens place.

This one is tricky. The number 7 in the ones place is greater than five. Therefore the number 97 is rounded up to 100.
97 rounded to the nearest tens place is 100.

A pet owner has 5 cats. Each cat has 2 ears and 4 paws. Complete the double number line to show the numbers of ears and paws for

aleksandrvk [35]

Answer:

If there are 3 cats in the room, what is the ratio of ears to paws? 1 : 2

If there are 4 cats in the room, what is the ratio of paws to ears? 2 : 1

If all 5 cats are in the room, how many more paws are there than ears? the number of paws is twice as more than the number of ears, we have 10 more paws than ears.

Step-by-step explanation:

You can see the double number line for this situation in the attached photo.

So as we can see in the double number line diagram, if there are 3 cats in the room we would have an ears to paws ratio of 6 : 12 , which simplified would be 1 : 2, meaning that for every ear there are 2 paws.

For the next question, if there are 4 cats in the room, the paws to ears ratio would be 16 : 8, simplified to 2 : 1, meaning that for every 2 paws there is 1 ear.

And for the last question, if all 5 cats are in the room, we have that the paws to ears ratio is 20 : 10, simplified again to 2 : 1, meaning the number of paws is twice as more than the number of ears, so in this case we have 10 more paws than ears.
