A spinner with 12 equally sized slices has 12 yellow slices. The dial is spun and stops on a slice at random. What is the

saveliy_v [14]

Answer:

1/1

Step-by-step explanation:

The reason why is because the spinner has 12 slices and on that spinner there is 12 yellow slices meaning all the slices on the spinner are yellow.

This means it is a 100% chance to land on yellow but 100% aas a fraction is 100/100.

You can simplify 100/100 a hundred times to 99/99 to 98/98 you can keep doing it but it's lowest form is the lowest number besides zero and that is 1 so it's lowest form is 1 out of 1 or 1/1 or 100%.

Hope this helps have a great afternoon:)

Option d: Yes, Jacob is correct. The median amount he makes is $84.00 in a day.

Explanation:

It is given that Jacob's daily tips for week are $99, $78, $58, $91, $90, and $68.

We need to determine the median of how much money he makes in daily tips.

Thus, to determine the median, first let us arrange the tips in ascending order.

Ascending order: $58, $68, $78, $90, $91 and $99

Since, the group is an even number of terms, let us add the two middle terms and divide by 2.

Median = $\frac{78+90}{2} =84$

Thus, the median is 84.

Hence, The median amount Jacob makes is $84.00 in a day.

Thus, Option d is the correct answer.
