# In the Numbers Game, a state lottery, four numbers are drawn with replacement from an urn containing balls numbered 0-9, inclusive. Find the probability that a ticket holder has the indicated winning ticket. (Put your answer to three decimal places.) Three digits in exact order.

P(first number correct) = 1/10
P(second number correct) = 1/10
P(third number correct) = 1/10
P(fourth number correct) = 1/10

P(all four numbers correct) = 1/10 x 1/10 x 1/10 x 1/10
= 1/10000
= 0.0001

Which ordered pair is a solution of the equation 2x − y = 9 (-4,1) (-2,5) (5,1) (6,-3)

In order to confirm if which ordered pair is a solution of the given equation above, we can just simply plug in the values.
So based on my solution, the correct answer would be the third option: (5,1)
So let us try to plug in the values.
2(5) - 1 = 9
10 -1 = 9
9 = 9

Find the multiplicative inverse of 6 + 2i.

The solution to the problem is as follows:

First thing to do is get rid of the i. Multiplying by 6 - 2i will do this

( 6 + 2i)(6 - 2i) = 6^2 - (2i)^2 = 36 - 4(-1) = 36 + 4 = 40

Dividing by 40 gets you 1

(6 + 2i) (6-2i)/40 = 1

The answer is (6 - 2i)/40 = (3 - i)/20

I hope my answer has come to your help. God bless and have a nice day ahead!

The price of a cup of coffee was $2.65 yesterday. today, the price fell to$2.50 . find the percentage decrease. round your answer to the nearest tenth of a percent.

We must find the difference between prices. $2.65 -$2.50 = $0.15. Now we need to calculate what percent$0.15 is of $2.65. It is 5.7%! The price decreased, so it is a 5.7% decrease!

The sum of the measures of any two angles of a triangle is greater than the measure of the third angle. B. The sum of the lengths of any two sides of a triangle is greater than the length of the third side. C. The longest side of a triangle is opposite the largest angle. D. The largest angle of a triangle is between the two longest sides. we know that The triangle inequality theorem states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side so Let a,b,c------> the length sides of a triangle The theorem states that three conditions must be met case 1) case 2) case3) therefore the answer is the option B.

In a typical month, it sells between 35 and 45 footballs and between 40 and 55 baseballs. The store has no more than 80 footballs and baseballs in stock during the month. What is the maximum profit the store can make from selling footballs and baseballs in a month? We are given with$6 profit per football sold and $5.50 profit per baseball sold. There are 35-45 footballs and 40-55 baseballs sold but there are only 80 balls stock in the store. The maximum profit is incurred from selling more of football and less of baseball. The equal number could also be possible. Having 40 footballs and 40 baseballs can be a possibility. However, having 39 footballs and 41 baseballs has smaller profit than the equal number. Likewise, 41 footballs lead to 39 baseballs which are not within the range. The answer is 40 footballs and 40 baseballs with a total profit of$460.

If np >5 and nq>5 estimate P (fewer than 4) with n=13 p=0.4 by using normal distribution as an approximate to the binomial distribution if np <5 or nq< then state that the normal approximation is not suitable.

The Normal approximation to the binomial

is as follows

mean=13(.5)=6.5
variance=6.5(.5)=3.25
Pr[fewer than 4]=
Pr[N<=3] Apply the continuity correction
Pr[N<=3.5]~=Pr[Z<3.5-6.5/sqrt(3.25)]=

Pr[Z<-1.66]=0.048457226

Sophia is saving money for a new bicycle. The bicycle will cost at least $623. Sophia makes$8.22 per hour. Which inequality could be used find the number of hours Sophia needs to work to make enough money to buy a new bicycle? $8.22h >$623 $8.22h ≤$623 $8.22h ≥$623 $8.22h <$623

C.$623 Step-by-step explanation: We are given that Sophia is saving money for a new bicycle. The bicycle will cost atleast$623.

Sophia makes $8.22 per hour. We have to find the inequality that could be used to find the number of hours Sophia needs to work to make enough money to buy a new bicycle. Let Sophia works h hours to make enough money to buy a new bicycle. Sophia makes money per hour =$8.22

Total money made by Sophia in h hours =
