<u>The probability is </u><u>1/12</u>

The probability of choosing a nickel is 9/18 = 1/2. The probability of choosing a dime is 3/18 (because there are 3 dimes and since there is replacement, we still have 18 total coins to choose). With these, we get: (1/2) * (3/18) = 3/36 = 1/12

What is the slope of the line that passes through the pair of point? (5, 7), (2, 1)
choli [55]

The slope of the line that passes through the pair of point (5, 7), (2, 1) is 2

<em><u>Solution:</u></em>

Given that line that passes through the pair of point (5, 7), (2, 1)

To find: slope of the line

<em><u>The slope of line is given as:</u></em>

For a line passing through two points (x_1, y_1) and (x_2, y_2) slope is given as:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

Here in this problem,

\left(x_{1}, y_{1}\right)=(5,7) \text { and }\left(x_{2}, y_{2}\right)=(2,1)

<em><u>Substituting the values in above formula,</u></em>

m=\frac{1-7}{2-5}=\frac{-6}{-3}=2

Thus the slope of given line is 2

ArbitrLikvidat [17]

Answer: 381.51 cubic inches

Step-by-step explanation:

1. Use the formula: V = πr^{2}h, or in this case, 3.14(4.5^{2})(6)

2. Simplify to 3.14(20.25)(6)

3. Simply multiply all three numbers using a calculator, or one by one if that's the preferred option.

4. You get: 381.51 cubic inches.

10p-2(3p-6)=4(3p-6)-8p
lisabon 2012 [21]

Answer:

undefined / no solution

Step-by-step explanation:

10p - 2(3p-6) = 4(3p-6) - 8p

10p - 6p - 12 = 12p - 24 - 8p

4p - 12 = 4p - 24

0 = -12

0 cannot equal -12
