Each serving for a box of trail mix is 3/8 of a cup.

Enter the number of 3/8 -cup servings there are in 1 1/2 cups of trail mix.

Answers

Answer:

It's 4

Step-by-step explanation:

It asks how many 3/8 cups are in 1 1/2 cups. So, we divide.

1 1/2 ÷ 3/8. We have to change the 1 1/2 into a improper fraction. 1 1/2 = 3/2. 3/2 ÷ 3/8 = 3/2 ÷ 8/3 = 24/6. Simplify, and you get 4. :)

Find the area of a square that has a side length of 4.8 cm.

Answers

A=23.04cm² , A=a2=4.82=23.04cm²

Answer: 23.04 cm.

Step-by-step explanation:

To find the area of something, we use the equation l x w, or length x width.

A square has 4 sides, and all 4 sides are equal. If the length of a square is 4.8, then the width is also 4.8 since all 4 sides of a square are equal.

Since we're using the equation l x w to find the area of the square, we have to multiply 4.8 x 4.8.

4.8 x 4.8 = 23.04.

Therefore, the area of the square is 23.04 centimeters!

You roll a spinner that is numbered 1-4. What is the probability of landing on a number less than 3 and then landing on a 4? (determine the answer and explain your process for doing so)

Answers

Answer:

The probability is 1/4

Step-by-step explanation:

So there's 4 possible outcomes. So if you roll the spinner and you can only get one outcome. So it'll be 1/4.

Answer:

P(<3, then 4) = 1/2 x 1/4 = 1/8

Step-by-step explanation:

probability of a number less than 3 would mean landing on a 1 or 2, which has a prob. of 1/2

probability of landing on the number 4 is 1/4

Determine whether the function rule models discrete data, continuous data, or neither.


A hardware store sells bolts for $.35 apiece. The function C(p) = 0.35p relates the total cost of the bolts to the number p purchased.


A.
neither


B.
continuous data


C.
discrete data

Answers

Answer:

C.

discrete data

Step-by-step explanation:

The given function is:

                                                  C(p) = 0.95p

Where p represents the number of bolts purchased. We can calculate the cost based on the number of bolts purchased.

An important distinction between discrete and continuous data is that the continuous data is measured while discrete data is calculated or counted. Since we are obtaining the data by calculation, it must be discrete data.

The function can take on only specific values. For example for p=0, C is 0 and for p=1 the value of C is 0.95. The function cannot take any value in between 0 and 0.95. This is a characteristic of discrete function. A continuous function can take all possible values in an interval.  

Therefore, the answer to this question is: The Function models discrete data.
