Dimas [21]3 years ago

Answer:

A.  The mean will increase.

Step-by-step explanation:

The mean is the average of the numbers. You just add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

84 + 75 + 76 + 80 + 48 + 75 = 438

438 / 6 = 73

mean = 73

The outlier is 48, so when you remove it, there will now be only five numbers in the set, and the mean will increase in size.

84 + 75 + 76 + 80 + 75 = 390

390 / 5 = 78

NEW mean (without the outlier) : 78

sweet [91]

Answer: there are 25 red flowers in Sakura's garden.

Step-by-step explanation:

In Sakura's garden, for every 5 red flowers, there are 10 yellow flowers. This means that if there are 10 red flowers, there would be 20 yellow flowers. if there are 20 red flowers, there would be 40 yellow flowers. Therefore, the ratio of red flowers to yellow flowers in the garden is

5/10 = 10/20 £= 20/40 = 1/2 = 1:2

Total ratio = 2 + 1 = 3

If there are 75 total red and yellow flowers, then the total number of red flowers are in Sakura's garden would be

1/3 × 75 = 25
