A, the interquartile range is 10, does not fit.
The interquartile range is found by subtracting the upper quartile and the lower quartile; in a box-and-whisker plot these are the outer edges of the box. In this case, they are 40 and 20; 40-20 = 20, not 10.
Answer:
1,114 people
Step-by-step explanation:
The equation 
is the equation of the regression line that predicts the number of people attending a county fair, where x is the number of years after 2000.
To find the number of people that are expected to attend the fair in 2026, we determine how many years have passed and substitute into the equation.
From 2000 to 2026,
have passed.
The expected number who will attend the fair in 2026 is
To the nearest whole number 1,114 people will attend in 2026
Answer:
The food store used 3 lbs of clusters, 6 lbs of granola, and 3 lbs of raisins.
Step-by-step explanation:
Given that:
A food store makes a 12-lb mixture of granola, clusters, and raisins.
The cost of granola = 1.00 per pound
The cost of clusters = 3.00 per pound
The cost of raisins = 2.00 per pound
Let granola be = g; cluster be c and raisins be r
Then, g + c + r = 12
Similarly, the mixture calls for twice as much granola as clusters.
2c + c + r = 12
3c + r = 12
r = 12 - 3c
2c(1) + 3c + 2r = 21
2c + 3c + 2r = 21
5c + 2r = 21
5c + 2(12 -3c) = 21
5c + 24 - 6c = 21
24 - c = 21
-c = 21 - 24
c = 3
Thus, cluster c = 3 lbs
granola = 2(c) = 2(3) = 6 lbs
raisins = 12 - 3c
= 12 - 3(3)
= 12 - 9
raisins = 3 lbs
Answer:
For the Chinese students the mean is 6.8 and the median is 7. The mode is 6 and the range is 5.
Step-by-step explanation:
The mean is just the Sum of all the number on the left columns divided by the number students. The sum is 204 and there are 30 students. So divide 204 by 30 and you get 6.8.
To find the median for Chinese students, all you need to do is arrange the numbers from least to greatest and then find the number,or numbers, that are left in the middle. So you cross off numbers on both ends until you get to the middle. Ex: you are given the numbers 12,7, and 5. Arrange them like so, 5, 7, 12. cross off the numbers on the sides and you get 7 as your median. Because 30 is divisible by 2, you end up with two numbers in the middle. When that happens, you add both middle numbers together and then divide by 2.
Finding the mode shouldn't be too hard if you've arranged the numbers from least to greatest. The mode is just the number you see most often in a set of data. In this case, 6 is the most common number of letters a Chinese student has.
Lastly, to find the range, you need to find the lowest value or number and subtract it from the highest value or number. Here the highest value is 9 and the lowest is 4. So 9 - 4 = 5.
