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.

A protein mix claims to contain a bonus of 20% more mix than the usual size container. If the bonus size contains 18 ounces of m
agasfer [191]

Answer:

The usual size of the container is 15 ounces.

Step-by-step explanation:

Consider the provided information.

A protein mix claims to contain a bonus of 20% more mix than the usual size container.

Let the usual size of the container was x ounces.

They increase 20% of usual size and the bonus size is 18 ounces.

Therefore, the new size should be:

x+20\%x=18

x(1+0.20)=18 (∴20%=\frac{20}{100}=0.20)

x(1.20)=18

x=\frac{18}{1.20}

x=15

Hence, the usual size of the container is 15 ounces.

I need help pls and thank you...
lapo4ka [179]

Answer:

AB = 32

Step-by-step explanation:

Since line l bisects AB at point M, we have AM = MB.

4x = 5x - 4

4x + 4 = 5x

x = 4

AM = 4(4) = 16, MB = 5(4) - 4 = 16.

So AB = AM + MB = 16 + 16 = 32.
