Use The Bar Graph To Find The Experimental Probability Of Spinning A 5 Or 7.

Answers

Answer 1

Answer:

6/23

Step-by-step explanation:

spinner was spun 23 times, 5 times it landed on 5 and once on 7, so:

P(5 or 7) = 5/23 + 1/23 which is 6/23

Answer 2

Answer: 6/23

Step-by-step explanation:

Experimental probability uses the numbers from the experiment.

The number of 5s and 7s total is 6.

Total spins is 23.

6/23

A circle has a diameter of 36 cm. Which expression could represent the area of this circle in square cm?

Answers

Answer:

Step-by-step explanation:

You haven't given the choices but I believe the equation below could represent the area of the circle:

(pi ~ 3.14) * (18)^2

The area for a circle is pi * radius squared, so to find the radius divide the diameter by 2.

Which expression is equivalent to -3x(x-4)-2x(x+3)?

Answers

Answer:

x(x^2 + 6)

Step-by-step explanation:

We are to simplify -3x(x-4)-2x(x+3).  Begin by performing the indicated multiplication.  We get -3x^2 + 12x - 2x^2 - 6x.

Combining like terms, we get    -5x^2 + 6x, which is equivalent to

                                                       x(x^2 + 6)

Answer

=5x²+12x-6

Step-by-step explanation:

Prove for any positive integer n, n^3 +11n is a multiple of 6

Answers

There are probably other ways to approach this, but I'll focus on a proof by induction.

The base case is that n = 1. Plugging this into the expression gets us

n^3+11n = 1^3+11(1) = 1+11 = 12

which is a multiple of 6. So that takes care of the base case.

----------------------------------

Now for the inductive step, which is often a tricky thing to grasp if you're not used to it. I recommend keeping at practice to get better familiar with these types of proofs.

The idea is this: assume that k^3+11k is a multiple of 6 for some integer k > 1

Based on that assumption, we need to prove that (k+1)^3+11(k+1) is also a multiple of 6. Note how I've replaced every k with k+1. This is the next value up after k.

If we can show that the (k+1)th case works, based on the assumption, then we've effectively wrapped up the inductive proof. Think of it like a chain of dominoes. One knocks over the other to take care of every case (aka every positive integer n)

-----------------------------------

Let's do a bit of algebra to say

(k+1)^3+11(k+1)

(k^3+3k^2+3k+1) + 11(k+1)

k^3+3k^2+3k+1+11k+11

(k^3+11k) + (3k^2+3k+12)

(k^3+11k) + 3(k^2+k+4)

At this point, we have the k^3+11k as the first group while we have 3(k^2+k+4) as the second group. We already know that k^3+11k is a multiple of 6, so we don't need to worry about it. We just need to show that 3(k^2+k+4) is also a multiple of 6. This means we need to show k^2+k+4 is a multiple of 2, i.e. it's even.

------------------------------------

If k is even, then k = 2m for some integer m

That means k^2+k+4 = (2m)^2+(2m)+4 = 4m^2+2m+4 = 2(m^2+m+2)

We can see that if k is even, then k^2+k+4 is also even.

If k is odd, then k = 2m+1 and

k^2+k+4 = (2m+1)^2+(2m+1)+4 = 4m^2+4m+1+2m+1+4 = 2(2m^2+3m+3)

That shows k^2+k+4 is even when k is odd.

-------------------------------------

In short, the last section shows that k^2+k+4 is always even for any integer

That then points to 3(k^2+k+4) being a multiple of 6

Which then further points to (k^3+11k) + 3(k^2+k+4) being a multiple of 6

It's a lot of work, but we've shown that (k+1)^3+11(k+1) is a multiple of 6 based on the assumption that k^3+11k is a multiple of 6.

This concludes the inductive step and overall the proof is done by this point.

Step-by-step explanation:

In order to find the number of solutions, we have to expand both sides out first.

[tex]3(x - 2) + 7x = \frac{1}{2} (6x - 2)[/tex]

First, expand 3(x-2), which will obtain 3x-6.

Next, expand (1/2)(6x-2), which gives 3x - 1.

The result at this point should be as shown below:

[tex]3x - 6 + 7x = 3x - 1[/tex]

Now, we would shift all x terms to the left and all number terms to the right.

[tex]3x + 7x - 3x = - 1 + 6[/tex]

After simplifying, the final equation would be:

[tex]7x = 5[/tex]

6. No  because the frequency table shows only ranges of times.

4. Only the first group ran under 9 minutes.

5. 8 students ran 1 mile in under 10 minutes (the first two sections)

15 students took 11 or more minutes to run 1 mile (the last 2 sections)

15 - 8 = 7

6. No, because the frequency table shows only ranges of times.

There are 31 students in PE class, 6 students ran 1 mile in under 9​ minutes, 8 students are there who ran 1 mile in under 10 minutes than students who took 11 or more minutes to run that​ distance and no student ran a mile in exactly 12​ minutes.

​12:00-12:59                  9

3. The number of students in the PE class

6+2+8+6+9

=31

4. Only the first group ran under 9 minutes which is 6 students

5.  8 students ran 1 mile in under 10 minutes
