Abby's MAD is 45 and her IQR is 51.5. Caleb's MAD is 28 and his IQR is 16. The coach should choose Caleb.
MAD
Simply calculate the mean (average) of all the data and find the maximum deviation. Make sure you look at data both larger and smaller than the mean. e.g. Abby:
(146+147+178+231+195+209+207+219+187)/9 = 191
The data with the largest deviation from the mean is 146, so 191-146=45
IQR
To compute the quartiles, the data must be put into ascending order of value. I will use Caleb's data set as an example; please see the photo for details.
Therefore, because both Caleb's MAD and his IQR are lower than those of Abby, the coach should choose him.
Answer:
A. 144 feet.
Step-by-step explanation:
f(x) = -16x^2 + 96x.
The maximum height is 144, as time (x) = 3. More than 3 seconds after, it'll fall back down.
Answer:
second one
Step-by-step explanation:
Answer:
angle C =113 degree
Step-by-step explanation:
angle A + angle C =180 degree
angle C = 180 degree - angle A
angle C = 180 degree - 67 degree
=113 degree
Answer:
The 4 t h term is f(4) = 143
Step-by-step explanation:
<em>Explanation</em>:-
Given function f(1) = -4
Given 'nth' term is f(n) = -3f(n-1) +5
Put n =2 <em> f(2) = -3 f(2-1) +5</em>
= -3 f(1) +5
= -3 (-4) +5
= 12 +5
f(2) = 17
put n= 3
f(n) = -3f(n-1) +5
<em> f(3) = -3 f(3-1) +5</em>
= -3f(2) +5
= -3(17) +5
= -51+5
f(3) = -46
Put n=4
f(n) = -3f(n-1) +5
<em> f(4) = -3f(4-1) +5</em>
<em> f(4) = -3f(3)+5</em>
f(4) = -3(-46)+5
f(4) = 138 +5
f(4) = 143
<u><em>Final answer</em></u>:-
<em>The 4 t h term is f(4) = 143</em>
