Answer:

the statements given above are true.

Step-by-step explanation:

Given that Frederick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin.  

He spun a 4 five times.

The statements true are:

i) For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.

iii) If the number of trials is changed, the experimental probability also changes.

iv) If the number of trials is changed, the predicted number of outcomes also changes.

v) If the number of trials is changed, the number of experimental outcomes also changes.

Answer:

For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.; If the number of trials is changed, the experimental probability also changes. ; If the number of trials is changed, the predicted number of outcomes also changes. ;  and If the number of trials is changed, the number of experimental outcomes also changes.

Explanation:

The more trials you perform, the closer your experimental probability will be to the theoretical probability.  Thus the first statement is true and the second statement is false.

As the number of trials increases, the experimental probability changes; this is because for each trial, you will possibly have a different outcome.  Thus the third statement is true.

As the number of trials increases, the predicted number of outcomes changes.  This is because the predicted number will change to keep the ratio of predicted outcomes to number of trials the same.  Thus the fourth statement is true.

As the number of trials increases, the number of experimental outcomes changes.  This is because, as with number three, for each trial, you will possibly have a different outcome.  Thus the fifth statement is true.

We cannot change the theoretical probability by performing an experiment.  Thus the sixth statement is false.

Martha's mom is making party bags for all of her guests. She has 24 green gumballs and 33 blue gumballs. If she splits them even
Dmitry_Shevchenko [17]

Answer:

3 bags

Step-by-step explanation:

Suppose there are  

x

bags of candy.

If the  

33

blue gumballs are to be split evenly with no leftovers among the  

x

bags, then  

x

must divide evenly into  

33

.

If the  

24

green gumballs are to be split evenly with no leftovers among the  

x

bags, then  

x

must divide evenly into  

24

.

To get the largest number of bags (

x

),

x

must be the Greatest Common Divisor of  

33

and  

24

Factoring:

33

=  

3

×

8

24

=  

2

×

2

×

2

×

3

The only common factor is  

3

and therefore the product of the common factors is  

3

or, in other words,

the Greatest Common Factor is  

x

=

3

Write an equation for the line parallel to y= -2x+1 that contains (-2,5)
grin007 [14]

Answer:

y = - 2x + 1

Step-by-step explanation:

Parallels line have the same slope, when an equation is in the form y= mx + b, m is the slope. In this problem slope = - 2

Now with the slope what is missing is the y-intercept, the problem says that the line contains the point (-2, 5), replacing that point in the equation you can solve it to find the y-intercept

y = mx + b

5 = (-2)(-2) + b

5 = 4 + b

1 + b

y = - 2x +1

For this case we have the following expression:

\frac {216 ^ {n-2}} {(\frac {1} {36}) ^ {3n}} = 216

We multiply both sides by: (\frac {1} {36}) ^ {3n}

216 ^ {n-2} = 216 * (\frac {1} {36}) ^ {3n}

We divide both sides by 216:

\frac {216 ^ {n-2}} {216} = (\frac {1} {36}) ^ {3n}

To divide powers of the same base, we place the same base and subtract the exponents:

216 ^ {n-2-1} = (\frac {1} {36}) ^ {3n}\\216 ^ {n-3} = (\frac {1} {36}) ^ {3n}

Rewriting:

(6 ^ 3) ^ {n-3} = (\frac {1} {6 ^ 2}) ^ {3n}\\6 ^ {3n-9} = \frac {1} {6 ^ {6n}}\\6^{ 3n-9} * 6^{ 6n} = 1

To multiply powers of the same base, we place the same base and add the exponents:

6^{ 3n-9 + 6n} = 1\\6^{ 9n-9} = 1

We know that any number raised to zero is 1, a ^ 0 = 1.

So, for equality to be true:

9n-9 = 0\\9n = 9\\n = \frac {9} {9}\\n = 1

Answer:

n = 1
