In a particular lottery, 5 winning numbers are drawn from a set of 37 numbers. What is the probability of picking exactly 2 of the winning numbers in this lottery? Round your answer to the nearest
thousandth (three decimal places).

Answers

Answer 1

Since 5 winning numbers are draw and there are exactly 2 winning numbers, the other 3 numbers chosen have to be incorrect.

The 2 numbers picked right, there are 5C2=10 different possibilities.

The other 3 numbers are just picked from the rest of the 32 numbers. Getting there are 32C3=4960 different possibilities.

For each set of 2 correct winning numbers, you could have the 4960 different losing numbers to match up to make a unique set. This meant that there are 4690*10=46900 different total possibilities.

Now the total different outcomes of how you can choose the numbers are 37C5=435897 outcomes.

Now the way to find probabilities is want/total

The want is 46900 and the total is 435897

Doing the division you get the number rounded to the nearest thousandths as   0.107 or in percent form as

10.759% chance of picking exactly 2 winning numbers.

This seems like a competition problem of some sort therefore I assume that you already know what combinations in form nCk and permutation in form nPk means.

The ladder gets propped against the house, making a 75 degree angle with the ground. We can use the fact that cos(75°)=base distance/length of ladder to figure out the length of the base. Multiplying both sides by length of ladder we get, length of ladder×cos(75°)=base distance.Nov 6, 2019

The answer is 40 I got you fam

Answer:

The angle x, has the measurement of 40°

Step-by-step explanation:

Step 1:  Define complementary angles

Complementary Angles: Two angles are complementary when the sum of them is equal to 90°.  For example, 30° and 60° are complementary because they add up to 90°.

Step 2:  Figure out the complementary angle

Since ∠ABD and ∠DBC are complementary, that means that they should add up to 90°.  Since the angle value of ∠ABD is 50°, that means that the angle value of ∠DBC should be 90° - 50° = x.

90° - 50° = x

40° = x

Answer: The angle x, has the measurement of 40°

9x + 2 = -4(x + 6)

Answers

Answer:

The equation has 1 solution.

Step-by-step explanation:

Because you don't get the same answer on both sides, this equation does not have infinately many solutions. Because you don't get an invalid answer, such as 1 = 0, this equation doesn't have one solution. When you solve this equation, you'd get something similar to this

9x-2 = -4x-24 (distributive property)

13x-2=-24 (combine like terms)

13x=-22 (additive property of inversion)

x = -22/13

which is a valid, real-world solution.
