<u>Given</u>:
Given that there are 10 marbles in a bag. 4 are blue, 3 are black, 2 are white and 1 is red.
The marbles are selected by not replacing the drawn ones.
We need to the probability of selected a black marble and then a white marble without replacement.
<u>Probability</u>:
Let B denote the black marble.
Let W denote the white marble.
The probability of selecting a black marble is 
The probability of selecting a white marble without replacement is 
The probability of selecting a black marble and then a white marble without replacement is given by
Substituting the values, we get;
Thus, the probability of selecting a black marble and then a white marble without replacement is 
8k+14

Step-by-step explanation:
<em>To find out what she paid with the discount and no tax, turn the percentage into a decimal. To do that, divide it by 100.</em>
Then, multiply that by the total.
<em>Subtract that by the total.</em>
<em>Now, we need to find the sales tax. Again, we know to divide the percentage by 100 to get the decimal. In that case, 6.5% is now .065.</em>
Multiply that by the discounted price.
<em>Add that to the price.</em>
$
would be the total price.

Answer:
B)
and C) 
Step-by-step explanation:
Once a linear function has a constant rate of change, you just have to find the linear functions. Also, the other ones are quadratic functions, and their graph are parabolas, which don't have a constant rate of change.
Considering 
has a constant positive rate of slope 2.
has a constant negative rate of slope -7
Answer:
8
Step-by-step explanation:
–16 • 1/8 • 4 + 32 ÷ 2
Using PEMDAS, we multiply and divide from left to right since there are no parentheses or exponents.
-2 • 4 + 32 ÷ 2
-8 +32 ÷ 2
-8 + 16
Now we add and subtract from left to right
8
