Answer:
d=14.5
r=14.5/2=7.25
area=4πr^2=3.14×7.25×7.25=165.04 inches sq
Answer:
Std deviation would change but IQR would not change.
Step-by-step explanation:
Given that after entering the test scores from her Statistics class of 25 students, the instructor calculated some statistics of the scores. Upon checking, she discovered that she had entered the top score as 46, but it should have been 56.
When arranged in ascending order the last entry would be 56 instead of 46.
Hence this would not affect the middle entry or quartiles
i.e. in other words there would not be any change in the Interquartile range and Quartile 1 and Quartile 3 are not changed
But standard error would change. this is because total of all entries now increase by 10, so average would increase by 10/25 = 0.40
This in turn would change the mean deviation x-average for each entry and hence square of deviations. Thus variance would change and also standard deviation.
Answer:
x = 8/3 and y = 32/3
Step-by-step explanation:
Add the two equations, getting -3y = -32, thus y = 32/3
Sub for y in first equation, getting 5x + 32/3 = 24
5x = 40/3
x = 8/3
-1 3 5 8 13 It is because x is grows by the number you put in and you add the 5
5 small milkshake outcomes
5 medium milkshake outcomes
and
5 large milkshake outcomes
since there are only 5 flavors you can only make 5 different milkshakes unless you want to mix the flavors to make
5+10= 15 so you could make 15 that mixing each ice cream with each other and then mixing all of them.
