Every person has blood type O, A, B, or AB. A random group of people are blood-typed, and the results are shown in the table. A 2-column table with 4 rows is shown. The first column is labeled Blood Type with entries O, A, B, AB. The second column is labeled Number of People with entries 22, 20, 6, 2. Use the table to determine the following probabilities. The probability that a randomly chosen person from this group has type B is . The probability that a randomly chosen person from this group has type AB is . The probability that a randomly chosen person from this group has type B or type AB blood is .

Answers

Answer 1

Answer:

1 -- 3/25

2 -- 1/25

3 -- 4/24

Step-by-step explanation:

To find the probability of a randomly selected person being in any category, divide the amount of people in that category by the total amount of people.

We can find the total amount of people by adding the amount of people with each blood type.

Total = O + A + B + AB = 22 + 20 + 6 + 2 = 50

There are 50 total people in this group. Now we can find the probability of randomly selecting a person from each category.

Probability of type B

There are 6 people with type B blood. The probability of randomly selecting a person from this group is 6/50, or 3/25.

Probability of type AB

There are 2 people with type AB blood. The probability of randomly selecting a person from this group is 2/50, or 1/25.

Probability of type B or AB

We need to find the amount of people who are in either group. There are 6 people with type B blood and 2 people with type AB blood, so 8 people satisfy this criteria. The probability of randomly selecting a person with type B or AB blood is 8/50, or 4/25.

Answers

Answer:

4(-5a + 3b - 2)

Step-by-step explanation:

Aside from changing the order of the terms so that the "a" term comes first and the "b" term second, there's nothing you can do with this expression -20a -8 + 12b.  But notice that 4 is a factor common to all three terms, and therefore it can be factored out:

Rearranging the terms, we get

-20a + 12b - 8  =  4(-5a + 3b - 2)

Salma suggested they sol a Grande box with 24 cupcakes. The ratio of
chocolate to vanilla cupcake is the same ratio of chocolate to vanilla for the
small box. Salma says that she can use equivalent ratios lo find how many
cupcakes in the Grande box are chocolate. What does she mean by that? How
many chocolate cupcakes will that be?​

Answers

Answer:

12... If there is an even ratio between the two, then there is an even amount, so you divide 24 by 2 and you have 12 chocolate and 12 vanilla cupcakes in the Grande box.

Step-by-step explanation:

It izz wat it izzzz!!!

                              :)

Answer:

If the ratio of chocolate to vanilla cupcakes is the same, that would make there 12 chocolate and 12 vanilla cupcakes.  She means that she can use equivalent ratios by, lets say the grande box had 100 cupcakes, then we know 50 are chocolate. We don't know how many chocolate cupcakes that will be because we don't know how much bigger the bigger box of cupcakes is.

Cedric has 200 songs on his Apple Music account. Of these songs, 24 are Indie songs. What percent of Cedric's songs are Indie songs?

Answers

Answer:

12%

Step-by-step explanation:

First put it into a fraction 24/200

Half it to make it to 100%

12/100=100%

Final answer:

To find the percentage of Cedric's songs that are Indie songs, divide the number of Indie songs by the total number of songs and multiply by 100%. The percentage of Indie songs is 12%.

Explanation:

To find the percentage of Cedric's songs that are Indie songs, we need to divide the number of Indie songs by the total number of songs and then multiply by 100.

So, the percentage of Indie songs is calculated as:

Percentage of Indie songs = (Number of Indie songs / Total number of songs) * 100% = (24 / 200) * 100% = 12%.

$42

Answers

Answer:

 Justin has a lower mean tip for the week with $42.

Step-by-step explanation:

To find the mean you must add all the numbers and then divide the sum by how many numbers there are.

For Justin you must add 32 + 45 + 50 + 33 + 50 then you'll get the sum 210. There are 5 numbers so you divide 210 by 5 which gives you the quotient 42.

As for T.J. you add 58 + 48 + 40 + 42 + 42 which gives you the sum of 230. Then you divide 230 by 5 since there's 5 numbers. Now you have the quotient of 46.

46 is greater than 42 so Justin has the lower mean.

Answer:

Justin by 4

Step-by-step explanation:

you add all the numbers for T.J. and for Justin separately and divide by five. you get 42 for Justin and 46 for T.J.

are they different?

Answers

1. 10/8-4/8= 3/4
2. 10-4= 6
The difference is the answers/solutions
Final answer:

The subtraction of 10/8 - 4/8 is similar to 10-4 only in the general subtraction process, but they differ in the types of numbers used (fractions vs. whole numbers) and the results generated (a fraction vs. a whole number).

Explanation:

The process of subtracting 10/8 - 4/8 is similar to subtracting 10-4 because in both cases, you are subtracting one number from another (~subtraction process~). However, they are different in terms of the kind of numbers used for subtraction. In the first operation, we are subtracting fractions while in the second operation, we are subtracting whole numbers.

To elaborate, in 10/8 - 4/8, they have the same denominators (8), so it's straightforward to subtract the numerators (numbers on top of the fraction): 10 - 4 = 6. So, the result is 6/8, which simplifies to 3/4.

In 10 - 4, the operation is simpler because we are working with whole numbers. By subtracting 4 from 10, we get 6 as the result. So, the results of the operations bear another difference, one yields a fraction, the other yields a whole number.
