For this case we have the following fraction:
To write three equivalent fractions, what we must do is multiply the numerator and the denominator of the expression by the same factor.
We have then:
For k = 3:
For k = 5:
For k = 2:
Answer:
the three equivalent ratio of 5/7 are:
B.He incorrectly determined the actual number of times he chose a red card.
C.He used too few trials for the sample space.
D.He used too many trials for the sample space.
Answer: C. He used too few trials for the sample space.
Step-by-step explanation:
Given: Josh used a standard deck of 52 cards to conduct an experiment.
As half of the cards in the deck were red.
If we take sample space= 52 cards
Then probability of getting a red card
But Josh took 8 cards as sample space which is not enough for the sample space.
therefore, C. is the right answer. "He used too few trials for the sample space."
Answer:
Option C - He used too few trials for the sample space.
Step-by-step explanation:
Given: Josh used a standard deck of 52 cards to conduct an experiment. Half of the cards in the deck were red. The other half were black.
Josh predicted that he would choose a red card in 4 out of 8 trials.
When he conducted the experiment, he actually chose a red card 6 out of 8 times.
To find : Which explains the most likely reason for the discrepancy between Josh’s predicted and actual results?
Solution :
Sample space = 52 cards
As half of the cards in the deck were red.
Probability of getting a red card is
He predict and conduct to choose a red card out of 8 trials which is not enough for the sample space.
Therefore, Option C is correct.
He used too few trials for the sample space.
Answer:
You're correct, it's 7.5!
Step-by-step explanation:
15% is still 15/100. So, if you to divide 100 by 2 to convert it to 50, then you divide 15 by 2 as well! And the answer to that is 7.5.
