Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Stacy spins the pointer 120 times and records the results. The pointer lands 30 times on a section numbered 2, 19 times on 3, 25 times on 4, 29 times on 5, and 17 times on 6. A winning spin is a 2.
Complete the table to find the theoretical and experimental probabilities of winning, and compare the two.

Answer 1
Answer: To compute the probabilities, just divide the number of times a number was landed by the total amount of outcomes. Stacy would spin a 6 approximately 0.14*50 = 7 times in 50 tries.

The diagram shows a circle inscribed in a square.12 m12 mWhat is the area of the shaded part of the diagram?

Answers

Answer:

A

Step-by-step explanation:

first lets find the area of the square

A=l*w

12*12=144 m^2

then lets find the are of the circle

A=pi*r^2

A=3.14*(d/2)^2

the diameter of the circle is 12m

A=3.14*(12/2)^2

A=3.14*(6)^2

A=3.14*36

A=113.04 m^2

Now, lets subtract the area of the circle form the area of the square

144-113.04= 30.96 m^2

So, the answer is A

what is the equation of this line

what is the equation of this line

Answers

Answer:

y=4x-6

Step-by-step explanation:

The equation of the line is y=mx+c where m is the slope and c is the intercept.

To find the slope, take two points \((x_{1},y_{1})\) and \((x_{2},y_{2})\) and use the equation \(m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\). Let's take (1,-2) and (2,2) as our two points:

\(m=\frac{2-(-2)}{2-1}=\frac{4}{1}=4\)

The y-intercept is where the line crosses the y-axis. We can see from the graph that the line crosses the y-axis at -6, therefore c= -6.

Now we can write the equation of this line: y=4x-6

Answer:

The answer is y=4x-6

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?

Answers

C(7, 4) = 7! / (4!(7-4)!) = (7 * 6 * 5) / (3 * 2 * 1) = 35

and

C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287

Multiply these two combinations since the faculty members and students are selected independently:

Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045

Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
To determine the number of ways to form the committee with 4 faculty members and 5 students, we need to calculate the combinations of faculty members and students separately and then multiply them together.

For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:

C(7, 4) = 7! / (4!(7 - 4)!) = 35.

So, there are 35 ways to select 4 faculty members from the 7 eligible ones.

For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:

C(13, 5) = 13! / (5!(13 - 5)!) = 1287.

Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.

To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:

35 * 1287 = 44,895.

Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

Step-by-step explanation:

Question: (4 x 10⁴)(2 x 10¹)

Answer:

Using the knowledge that a x 10ⁿ = a followed by ⁿ zeroes (eg: 5 x 10³ = 5,000)

We know that:

4 x 10⁴ is equal to 40,000

2 x 10¹ is equal to 20

Using the knowledge that (a)(b) = a x b, our next step would be to multiply those figures together.

40,000 x 20. We can do this without a calculator by counting how many zeroes are there.

Since there’s 5 zeroes, we know our answer will have 5 zeroes and we can take those 5 zeroes out of our equation:

So instead of 40000 x 20, we have 4 x 2 which we know is 8. Using our knowledge that our answer will have 5 zeroes, 40000 x 20 is equal to 800,000 (8 followed by 5 zeroes).

Our final step is to put that number into scientific notation. We know that 800,000 contains 5 zeroes, therefore 800,000 in scientific notation is:

8 x 10⁵

The correct answer would be D.

I hope this made sense and helps you and if you have any questions or think that I’ve made a mistake please let me know!

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:  Choice A is correct

Explanation:

The LCM of the coefficients 14 and 16 is 112 because (14*16)/2 = 112. We multiply the values and divide by the GCF 2.

The 'a' terms are \(a^5\) and \(a^3\). We pick the one with the largest exponent when forming the LCM. Go for the smallest exponent when finding the GCF. Similar situations occur with the b and c terms as well.

So that's how we end up with \(112a^5b^4c^2\) as the LCM.

Side note: Choice D is the GCF of the two given expressions.
