The mean is 4.93333 (3 is repeating)

Explanation

So mean is just the sum of the numbers divided by the number of terms
So we would solve this by adding up all terms as shown here

10.6 + 4 + 4 + 6 + 4 + 1 = 29.6 = sum

Then we will divide the sum by the number of terms which is 6 in this case to get our mean as shown here

29.6 / 6 = 4.9333

The mean is 4.9333 (3 is repeating)

Together Kate and Matt have 47 cards. If Kate and Zach combine cards they have 126. If Matt and Zach combine they have 93. How m

Ede4ka [16]

Answer:

Matt has 7 cards.

Step-by-step explanation:

Let K, M and Z represent number of cards that Kate, Matt and Zach have.

We have been given that together Kate and Matt have 47 cards. We can represent his information in an equation as:

$K+M=47...(1)$

We are also told that Kate and Zach combine cards they have 126. We can represent his information in an equation as:

$K+Z=126...(2)$

Further, Matt and Zach combine they have 93. We can represent his information in an equation as:

$M+Z=93...(3)$

Upon subtracting equation (3) from equation (2), we will get:

$K-M=126-93$

$K-M=33$

$K=33+M$

Upon substituting this value in equation (1), we will get:

$33+M+M=47$

$33-33+2M=47-33$

$2M=14$

$M=\frac{14}{2}=7$

Therefore, Matt has 7 cards.

A recipe for a batch of 3 dozen chocolate chip cookies calls for 3 cups of flour, one cup of sugar, and 2 cups of chocolate chip

BaLLatris [955]

Answer:

2 cups of flour

2/3 cup of sugar

1 1/3 cups of chocolate chips

Step-by-step explanation:

3 dozen chocolate chip cookies

3 cups of flour

1 cup of sugar

2 cups of chocolate chips

The recipe is for 3 dozen cookies as stated above.

If you make 2 dozen cookies, then you are making 2/3 of the recipe since 2 is 2/3 of 3.

That means you need 2/3 of all the ingredients.

2/3 × 3 dozen chocolate chip cookies

2/3 × 3 cups of flour

2/3 × 1 cup of sugar

2/3 × 2 cups of chocolate chips

We simplify the amounts to:

2 dozen chocolate chip cookies

2 cups of flour

2/3 cup of sugar

1 1/3 cups of chocolate chips
