Suppose jamal fell during one race and recorded a time of 210s. Which of the mean, median, and mode would be most affected

Answers

Answer:

Mean would be most affected

Step-by-step explanation:

The mean is defined as the average value . If the data has extreme values then the average value automatically changes.

The median is the value which divides the data in to two halves. It is not affected by the extreme values. The middle value remains the same.

The mode is the value which occurs repeatedly. An extreme value in a data does not affect the mode.

For example I have 5 chocolate bars of sizes 5,6,7,7,9  and another 5 chocolate bars of sizes  5,6,7,7,12

Mean for the two sizes will be 34/5= 6.8  and 37/5=7.4

The median and mode in both sets is 7

So the mean is most affected with change in value.

Answer:

The price of one ticket is $76.

Step-by-step explanation:

5% of $330 is $16.50 and 45% of $330 is $148.50. Add those two together and then add $13 to it. You should get 178 and subtract it from 330 which leads you to 152. It asks for the price of one ticket, so you divide that by 2 which results to $76.

James has $10 in 5-cent and 10-cent coins in his change jar and counts 157 coins in total. How many 10-cent coins does he have?

Show working out!!

Answers

Answer:

10 cent coins = 43

Step-by-step explanation:

x = 10 cent coins

y = 5 cent coins

x + y = 157, then y = 157 - x

$10 = 1000 cents

0.10x + 0.05y =1000

substitute for y:

0.10x + 0.05(157 - x) = 1000

0.10x + 7.85 - 0.05x = 1000

combine like terms:

0.05x = 2.15

x = 43

y = 114
