Step-by-step explanation:
per week, while Theodore predicts that it
will grow 3/4 foot per week. The sunflower
grows 4 1/2 feet in 7 1/2 weeks. Which
statement is correct?
The sunflower grew at a rate of 0.6 feet per week, which is closer to Rachael's prediction of 0.4 feet per week. Therefore, Rachael's prediction was more accurate.
To solve this problem, we have to find the rate at which the sunflower grows in a week. The rate was given as 4 1/2 feet in 7 1/2 weeks. When we divide 4.5 feet (the total growth) by 7.5 weeks (the total time), we get a weekly growth rate of 0.6 feet.
Comparing this with the predictions made by Rachael and Theodore, we can see that the sunflower grew at a rate closer to Rachael's prediction of 2/5 feet per week, which is equivalent to 0.4 feet per week. Therefore, the statement-making Rachael's prediction correct is the accurate one.

Can someone explain me how to make this one step by step?
The median of the data set 42, 67, 33, 79, 33, 89, 21 is 42 after arranging the data set in ascending order.
A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.
It is given that:
The data set is:
42, 67, 33, 79, 33, 89, 21
First, arrange the number in ascending order:
21, 33, 33, 42, 67, 79, 89
From the definitionof the middle term representing the median of the data set 42, 67, 33, 79, 33, 89, 21
The middle term = 42
The median of the data set = 42
First, you want to put all the numbers in order from least to greatest.
Thus, the median of the data set 42, 67, 33, 79, 33, 89, 21 is 42 after arranging the data set in ascending order.
