Answer:

The experimental probability of rolling a 3 is greater than the theoretical probability of rolling a 3

Step-by-step explanation:

* Lets explain the difference between the theoretical probability and

experimental probability

- Theoretical probability is what we expect to happen

- Experimental probability is what actually happens when we try it out

- Both of them calculated by the same way, the number of possible ways

an outcome can occur divided by the total

* Lets solve the problem

- The table has two column;

# Number Cube # Observed Frequency

1 18

2 16

3 24

4 26

5 16

6 20

Total 120

∵ The experimental probability of rolling a 3 = 24/120 = 1/5 = 0.2

∴ The experimental probability of rolling a 3 = 0.2 = 20%

∵ The theoretical probability of rolling a 3 = 1/6

∴ The theoretical probability of rolling a 3 = 0.1666 ≅ 17%

∵ 20% is greater than 17%

∴ The experimental probability of rolling a 3 is greater than the

theoretical probability of rolling a 3

a coin lands on heads 200 times. the relative frequency of heads is 0.4. how many times was the coin thrown?

Kazeer [188]

Answer:

The number of times coin thrown was 500.

Step-by-step explanation:

Given:

A coin lands on heads 200 times. the relative frequency of heads is 0.4.

Now, to find the times coin was thrown.

Let the number of times coin thrown was be $x.$

Relative frequency = 0.4.

Number of lands on heads = 200.

So, to get the number of times coin was thrown we put formula:

$Relative\ frequency=\frac{Number\ of\ lands\ on\ heads}{Number\ of\ times\ coin\ thrown}$

$0.4=\frac{200}{x}$

By cross multiplying we get:

$0.4x=200$

Dividing both sides by 0.4 we get:

$x=500.$

Therefore, the number of times coin thrown was 500.

The sum of the measures of angle LMN and angle NMP is 180 degrees

Vaselesa [24]

Answer:

angle LMN is 153 degrees.

Step-by-step explanation:

180 = 15g + 18 +3g; combine like terms

180 = 18g + 18; subtract 18 on both sides

162 = 18g; divide 18 on both sides

g = 9

plug in: 15(9) + 18 = 153

Help ur boy out abcdefghijklmnopqrstuvwxyz

Umnica [9.8K]

Answer:

(-6, 10)
(-10, 9)
(-11, -6)
(-5, 1)

Step-by-step explanation:

(x,y) → (x-8, y+4)

1. (2, 6)

(2-8, 6+4)

(-6, 10)

2. (-2, 5)

(-2-8, 5+4)

(-10, 9)

3. (-3, -10)

(-3-8, -10+4)

(-11, -6)

ídk man u should connect it to (11, -7) since it's the only choice closest to the right answer, but If u can write the correct then write this. there's prolly an error in that quiz ídk

4. (3, -3)

(3-8, -3+4)

(-5, 1)

 still not in the choices nanii but (5, -14) is the only choice left and also the closest, and even if u use calculator the correct answer is still (-5, 1). sigh, I hope this helper at least

Question 2 of 5

AlekseyPX

Given:

The different recursive formulae.

To find:

The explicit formulae for the given recursive formulae.

Solution:

The recursive formula of an arithmetic sequence is $f(n)=f(n-1)+d, f(1)=a,n\geq 2$ and the explicit formula is $f(n)=a+(n-1)d$ , where a is the first term and d is the common difference.

The recursive formula of a geometric sequence is $f(n)=rf(n-1), f(1)=a,n\geq 2$ and the explicit formula is $f(n)=ar^{n-1}$ , where a is the first term and r is the common ratio.

The first recursive formula is:

$f(1)=5$

$f(n)=f(n-1)+5$ for $n\geq 2$ .

It is the recursive formula of an arithmetic sequence with first term 5 and common difference 5. So, the explicit formula for this recursive formula is:

$f(n)=5+(n-1)(5)$

$f(n)=5+5(n-1)$

Therefore, the correct option is A, i.e., $f(n)=5+5(n-1)$ .

The second recursive formula is:

$f(1)=5$

$f(n)=3f(n-1)$ for $n\geq 2$ .

It is the recursive formula of a geometric sequence with first term 5 and common ratio 3. So, the explicit formula for this recursive formula is:

$f(n)=5(3)^{n-1}$

Therefore, the correct option is F, i.e., $f(n)=5(3)^{n-1}$ .

The third recursive formula is:

$f(1)=5$

$f(n)=f(n-1)+3$ for $n\geq 2$ .

It is the recursive formula of an arithmetic sequence with first term 5 and common difference 3. So, the explicit formula for this recursive formula is:

$f(n)=5+(n-1)(3)$

$f(n)=5+3(n-1)$

Therefore, the correct option is D, i.e., $f(n)=5+3(n-1)$ .
