1/42

First, find the probability of Willie winning the grand prize. He has 1 ticket out of the 7 total tickets, so the probability is 1/7.

Now, find the probability of Emily winning the second prize. After the grand prize winner has been announced, there are only 6 tickets left. Emily has 1, so the probability is 1/6.

Finally, multiply the two probabilities together to find the probability that they will both happen together. To multiply fractions, multiply the numerators together and multiply the denominators together. This leaves us with (1 * 1) / (7 * 6), which is easy to simplify to 1/42, which is the final probability.

Tatesville had x inches of rainfall in April, (x + 1.3) inches of rainfall in May, and (2x + 0.5) inches in June. If x=2 inches,
inna [77]

Answer: 9.8 inches

Step-by-step explanation:

Since x = 2 inches

Rainfall in April = x inches = 2 inches

Rainfall in May = x + 1.3 = 2 + 1.3 = 3.3 inches

Rainfall in June = 2x + 0.5 = 2(2) + 0.5 = 4.5

Total rainfall = 2 + 3.3 + 4.5 = 9.8 inches

An expression that is equivalent to (-8a-1)-(-7a+5)
horrorfan [7]

Answer:

Step-by-step explanation:

(-8a - 1)- (-7a + 5) = -8a - 1 - 7a*(-1) + 5*(-1) { (-1) is disturbed to all the terms in (-7a +5)}

                         = -8a - 1 + 7a - 5

                         = -8a + 7a -1 - 5 {Combine like terms}

                         = -a - 6

Please help thanks !

Answer:

option D

Step-by-step explanation:

x^{2} + y^{2} = 16\\\\x^{2} = 16- y^{2}

equation 2:

\frac{x^{2}}{4} - \frac{y^{2}}{25} = 1

so we have:

\frac{16- y^{2} }{4}-\frac{y^{2}}{25}= 1
