Answer:
She divided wrong
Step-by-step explanation:
Answer:
k=4
Step-by-step explanation:
First, we can subtract 3k on both sides. It is ultimately easier to start by subtracting the term with a variable. This would result in 45=5k+25. Then, we can subtract 25 on both sides to get closer to isolating k. This becomes 20=5k. We can then divide by 5 on both sides. This means that k=4.
Answer:
45
Step-by-step explanation:
3 and 5 both go into 45 and 45 is the smallest for it
$34.80 because, if you add 15+2+21=58x12.00=696x0.05=34.80
Answer:
Step-by-step explanation:
.
a. Yolanda only wins if the cup lands upright.
From the experimental data we see that the probability of winning is 5 out of 50, or
10%. Therefore, if Yolanda plays 10 times she can expect to win 10% of 10 times = 1
time. She will lose 9 times. (Note: Ten trials is a very small number of trials, so we should not be surprised if Yolanda’s results are very different from the percentages
produced by the longer experiment.)
b. If Yolanda wins 1 time and plays 10 times, she will have spent $10 to play and won
back only $5, so she would have less money at the end of 10 games.
