Answer: f(x) = 0.30x + 2.50

This is the same as writing y = 0.30x + 2.50

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

Explanation:

x = number of pounds

y = f(x) = total cost in dollars

1 pound costs $0.30

x pounds cost 0.30x

This is ignoring the entrance fee

Tacking on the entrance fee leads to a total of y = 0.30x + 2.50

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

The independent variable is always x and the dependent variable is always y.

The independent variable (number of pounds) determines what the dependent variable (total cost) will be.

Deja has two baskets of berries. One of the baskets has 3 3/8 pounds of berries and the other basket has 2 7/8 pounds of berries

ElenaW [278]

Answer:

(b) The number of pounds of berries each person would receive is $1\frac{5}{8}$ pounds.

Step-by-step explanation:

The amount of berries in first basket = 3 3/8 pounds

Now, $3\frac{3}{8} = 3+\frac{3}{8} = 3 + 0.375 = 3.375$

So, the amount of berries in first basket = 3.375 pounds

The amount of berries in second basket = 2 7/8 pounds

Now, $2\frac{7}{8} = 2+\frac{7}{8} = 2 + 0.875 = 2.875$

So, the amount of berries in second basket = 2.875 pounds

Now, the total berries = Berries in ( First + Second) basket

= 3.375 pounds + 2.875 pounds

= 6.25 pounds

So, the number of pounds each person would have = $\frac{\textrm{Total weight of viable berries}}{\textrm{4}} = \frac{6.25}{4} = 1.5625$

Now, $1.5625 = 1 + 0.5625 = 1 + \frac{5625}{10000} = 1 + \frac{5}{8} = 1\frac{5}{8}$

So, the number of pounds of berries each person would receive is $1\frac{5}{8}$ pounds.

What is the value of 6x-3x +7 if x=9?

Lynna [10]

$6x - 3x + 7 \\ 3x + 7 \\ 3(9) + 7 \\ 27 + 7 \\ = 34$
Combine like terms and "plug in" x into the equation to eventually get 34 after some addition

Given :

Scores Number of students

0 1

1 2

2 5

3 3

4 6

5 7

6 9

To Find: Mean

Solution:

Mean = $\frac{\text{Sum of all scores}}{\text{number of students}}$

Mean = $\frac{0 \times 1+1\times 2+2\times 5+3\times 3+4\times 6+5\times 7+6\times 9}{1+2+5+3+6+7+9}$

Mean = $\frac{134}{33}$

Mean = $4.06$

Hence, The Mean of baseball score is 4.06 .
