Answers

Answer 1
Answer:

Answer:

22% probability the student is a junior.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes:

The table says that:

There are 4 + 6 + 2 + 2 + 3 + 4 + 6 + 6 + 3 = 36 total students.

2 + 6 = 8 are juniors.

If a student is selected at random, find the probability the student is a junior.

8/36 = 0.2222 = 22.22%

Rounding to the nearest whole percent, 22% probability the student is a junior.

Answers

Answer:

x = 4(y + 6)/5

Step-by-step explanation:

2x - y = (3/4)x + 6

2x - (3/4)x = y + 6

(8x - 3x)/4 = y + 6

5x/4 = y + 6

5x = 4(y + 6)

5x = 4y + 24

x = (4y + 24)/5

Therefore, x = 4(y + 6)/5

Laura is stuck in aisle six at the supermarket trying to decide which jar of peanut butter to buy.She can buy a 16-ounce jar for $2.59 or a 24-ounce jar for $3.29. Which jar has a lower unit price,
per ounce?

Answers

Answer: 24 ounce jar

Step-by-step explanation:

Unit price of 16 ounce jar

= 2.59 / 16

= 0.161875

Unit price of 24 ounce jar

= 3.29 / 24

= 0.137083

Each of the following tables defines a relationship between an input x and an output y. Which of the relationships represent functions? Table A x -8 -3 0 6 y 24 4 9 72 Table B x 9 15 24 38 y -14 -16 53 29 Table C x 15 24 24 100 y -16 53 29 7 Table D x -8 6 0 6 y 24 4 9 72 a. Table A and Table C b. Table A and Table B c. Table B and Table C d. Table C and Table D Please select the best answer from the choices provided

Answers

The relationship representing the function as per the input and output value is given by option b. Table A and Table B.

In order for a relationship between an input x and an output y to represent a function,

each input value x must be associated with exactly one output value y. Let's analyze the given tables:

Table A:

x -8 -3 0 6

y 24 4 9 72

Table B:

x 9 15 24 38

y -14 -16 53 29

Table C:

x 15 24 24 100

y -16 53 29 7

Table D:

x -8 6 0 6

y 24 4 9 72

Let's examine the options:

a. Table A and Table C: Table A represents a function because each x value corresponds to a unique y value.

Table C has duplicate x values, which means it doesn't represent a function.

b. Table A and Table B: Both Table A and Table B represent functions because each x value is associated with a single unique y value in both tables.

c. Table B and Table C: Table B does not represent a function

because the x value 24 is associated with two different y values (-16 and 53) in Table B.

Table C does not represent a function either because of the duplicate x value 24.

d. Table C and Table D: Similar to options a and c,

Table C does not represent a function due to duplicate x values.

Table D represents a function as each x value is associated with a unique y value.

Therefore, based on the analysis above, the correct answer for the function is option b. Table A and Table B.
