In a lottery, the top cash prize was $642 million, going to three lucky winners. Players pick five different numbers from 1 t

kramer

Answer:

$\frac{10}{53 \times 46 \times 26}$

Step-by-step explanation:

The probability of matching the number drawn on the gold ball is

$\frac{1}{46}$

The number of possible pairs of numbers from 1 to 53 is

$\binom{53}{2} = \frac{53 \times 52}{2} = 53 \times 26$

Choosing 5 numbers, you are choosing 10 different pairs:

$\binom{5}{2} = \frac{5 \times 4}{2} = 10$

Therefore the probability of correctly matching the drawn pair is

$\frac{10}{53 \times 26}$

Thus, the probability of winning (matching the pair AND the gold ball) is

$\frac{10}{53 \times 46 \times 26}$

Find the slope of the line passing through the points (-3, 7) and (2, -6)

ruslelena [56]

Answer:

Step-by-step explanation:

$Slope =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\=\dfrac{-6-7}{2-[-3]}=\dfrac{-6-7}{2+3}\\\\\\=\dfrac{-13}{5}$

Find the sum (3/7m-3+4n)+(2/7m-2m+6)

aleksley [76]

Answer:

(5/7)m + 2n + 3

Step-by-step explanation:

Rewrite 3/7m as (3/7)m for added clarity, also 2/7m as (2/7)m.

Adding (3/7)m and (2/7)m results in (5/7)m.

Next, combine -3 and 6, which yields 3.

I expected that there'd be only one term in m in both quantities. (3/7)m - 3 + 4n does have only one term, but (2/7)m - 2m + 6) seems to have two m terms. I will assume that you actually meant (2/7)m - 2n + 6).

Combining like terms, we get (5/7)m + 3 + 4n - 2n, or

(5/7)m + 2n + 3
