You select a marble without looking and then put it back. If you do this 5 times, what is the best prediction possible for the number of times you will pick a pink marble?

Answers

Answer 1

Since the ratio of pink marbles to other marbles is 1:5 meaning only 1 pink marble for every five you pick usually, the number of times you might pick a pink marble is 1 if you did it 5 times.

Of the students in your class, 12% are left-handed. What fraction of the students are left-handed? Are there more right-handed or left-handed students? Explain. Write your answers in simplest form.

what is the fraction for the right handed people

Answers

Answer:

Step-by-step explanation:

12% is equivalent to 12/100. This reduces to 3/25. Thus, 3/25ths of the students are left-handed. The corresponding fraction for the right handed people is (25-3)/25, or 22/25ths. There are more right-handed people (22/25ths) versus left-handed people.

Yes the answer above is right. 12% of the class is left but in fraction form it is 12/100 because a whole percent is 100% so 12 out of 100 is 12% :) hope it helped

It would be 70 pages because 210 divided by 3 is 70

She can read 70 pages in 3 hours.

What is proportion?

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We are Given:

Giovanni can read 210 words per minute and, books contain 540 pages

So, she can read the portion of book

=210/540

= 21/54 per minutes

= 21/54 x 60

= 23.3 pages in one hour

and in 3 hours she can read

= 23.3 x 3

= 70 pages in 3 hours

A holiday meal cost $12.50 a person plus a delivery fee of 30$. Which equation is right?

1. y=30+12.50x
2. y= 12.50+30
3. 12.50x=30
4. y=12.50+30x

Answers

Answer:

1. y = 12.50x + 30

Step-by-step explanation:

A holiday meal cost $12.50 a person plus a delivery fee of 30$

Let x = number of people ordering a meal and y = total cost

It cost 12.50 per person so the cost regarding the number of people that orders food can be represented by 12.50x.

There is also a $30 delivery fee.

So the total cost would (y) = 12.50x + 30

The answer would be 1. 12.50 and 30 just swapped places.

y=12.50x= 30

Answer: See the diagram below

==========================================================

Explanation:

She starts off finding the mean of the data. So she adds up the values to get 48+54+57+62+69 = 290, and then divides by 5 to get the mean of 290/5 = 58. That explains why there's a 58 in the first row of the second column.

---------------------

For the next step, she subtracts 58 from each data item. If the result is negative, then go with the positive version (ie apply the absolute value)

|48-58| = 10|54-58| = 4|57-58| = 1|62-58| = 4|69-58| = 11

This leads to the list 10,4,1,4,11 which goes in the first slot labeled "drag and drop an item here". This is the list of distance values each item is from the mean.

---------------------

The last thing to do is find the mean of the set {10,4,1,4,11}

add: 10+4+1+4+11 = 30

divide by five: 30/5 = 6

The mean absolute deviation (MAD) is 6

This represents the average distance each data value is from the mean. The MAD tells us how spread out the data is. It's similar to the standard deviation.

V = 4/3πr^3

A sphere with a diameter of 20 yards has a radius of 10 yards, so its volume is ...
