Scarlett is practicing math fluency. She has 100 math operation flashcards with 42 addition problem cards, 56 subtraction cards, and 2 multiplication cards. Scarlett will time herself to see how fast she can solve the problems on seven cards. She chooses her seven cards and they are all addition cards. Is choosing all addition cards likely? Explain by running a simulation.

Part A: State the problem or question and assumptions. (2 points)

Part B: Describe the process for one repetition, including possible outcomes, assigned representations, and measured variables. (3 points)

Part C: Use digits from a table of random digits or use your calculator to perform one repetition. Submit the list of random digits and indicate those that represent addition cards. (3 points)

Part D: Suppose there was one repetition when all seven cards were addition cards after 200 repetitions of the simulation. State your conclusions from these results. (2 points) (10 points)

Answer 1

The problem is; To examine the chance that all chosen 7 cards are addition cards.

What is the probability of Selection?

A) 7 cards are drawn from 100 cards such that each set of 7 cards has an equal chance of being selected.

The problem is; To examine the chance that all chosen 7 cards are addition cards.

B) The process for One repetition is as follows;

Use the representation: numbers 1 to 42 represent addition cards, numbers 43 to 98 represent subtraction cards, and numbers 99 and 100 represent multiplication cards.

Randomly choose 7 numbers from 1 to 100 without replacement.

The following set of 7 numbers are selected using a table of random numbers.

65 60 44 97 30 3 83

Among these numbers, 3 and 30 represent addition cards.

44,60,65,83 and 97 are subtraction cards.

There are no multiplication cards.

The outcome is 2 addition cards, 5 subtraction cards and no multiplication cards.

C) From part b above, the random digits are

65 60 44 97 30 3 83

The fifth and sixth cards, that is, 30 and 3 represent addition cards.

D) If the event (all 7 cards are addition cards) happens once in 200 repetitions, the estimated likelihood of the event is 1/200 = 0.005.

Answers

Answer:

m∠SWX=39°, and m∠VWY=51°

Step-by-step explanation:

∠XWU and ∠VWY are vertical angles. Vertical angles are congruent.

∠XWU=∠VWY

we are given ∠XWU=(7x+2)° and ∠VWY=(4x+23)°, so:

7x+2=4x+23

3x+2=23

3x=21

x=7

Now substitute x for 7 in both expressions to get the measures of the angles.

∠XWU=(7(7)+2)°=(49+2)°=51°

∠VWY is also 51° because it is congruent to ∠XWU, but just to make sure:

∠VWY=(4(7)+23)°=(28+23)°=51°

we also need ∠SWX. We can see it makes a right angle with ∠XWU, so their sum is 90°.

∠SWX+51=90

∠SWX=39°

Answer:

7x+2 and 4x +23 are the same

so 7x+2=4x+23

7x-4x=23-2

3x=21

x=21/3

x=7

Plug it in to the angles

UWX = 7(7)+2 = 51

VWY = 51 because they are  vertically opposite

so because UWX is 51

SWU makes up 90

so you do 90-51 to get SWX

and thats equals to 39

In summary

VWY = 51

SWX = 39

Fiona has a box with 5 red buttons and 9 blue buttons.She randomly selected one button, took it out of the box, then selected another button.What is the probability that both buttons are red?
A.4/25
B.10/91
C.9/29
D.1/3

Answers

Answer:

B. 10/91

Step-by-step explanation:

Box has 5 red buttons and 9 blue buttons.

We add 5 and 9 to get the total buttons.

5 + 9 = 14

Then, we find the probability for a red button.

5/14 = .35

Now, that we've taken out 1 button.

The amount of buttons available changes.

14 - 1 = 13

There are 4 red buttons remaining.

The probability for a red button changes to 4/13.

4/13 = .30

Then, we multiply both probabilities.

.30 x .35 = .111

Convert to a fraction.

.111 = 10/91

Thus it would be B.

Answer:

Answer:

A

Step-by-step explanation:

Commenter is right cause I graphed it to doublecheck

The centre and radius of the circle is (2, 3) and 6 units respectively

What are equation of a circle?

The standard equation of a circle is expressed as:

(x – a)² + (y – b)² = r²

where:

centre = (a, b)r is the radius

Given the equation

(x – 2)² + (y – 3)² = 36

Compare

(a, b) = (2, 3)

r² = 36

r = 6 units

Hence the centre and radius of the circle is (2, 3) and 6 units respectively

what is the probability that you choose a yellow marble and then a blue marble assuming you replace the first marble?
(A bag of marbles contains 5 red, 3 blue, 2 green, and 2 yellow marbles.)

Answers

Answer:

1/24

Step-by-step explanation:

To find the first probability of getting a yellow marble, first you have to add up the total number of marbles:

5+3+2+2=12

There are two yellow marbles so the probability is:

2/12

Next is finding the probability of grabbing a blue marble. Since the first marble was replaced, we can still use the total number of marbles and the probability is:

3/12

Since the problem says to choose a yellow and then a blue, we will multiply the two.

2/12×3/12 = 6/144 = 1/24
