All these ratios people are having trouble with today.
Its pretty easy once you get the hang of it.
So they release 12 grizzly.
We can say 12/x since we dont know the amount of grizzly bears in total.
We can then set 12/x equal to 2/21 and solve for x by using cross multiplication
The IQR is the difference between Q3 and Q1.
First we need to get the data from the stem and leaf plot:
10, 23, 23, 28,] [33, 45, 80, 90
Since there are 8 data items Q1 would be the median of the lower half (4 items), both are 23 so Q1 is 23.
Q3 is the median of the upper half, since the middle numbers are not the same we need to average 45 and 80. (45 + 80)/2 = 62.5 so Q3 = 62.5
IQR = 62.5 - 23 = 39.5
Answer:
Option (2)
Step-by-step explanation:
Parent function has been given as,
f(x) = 
When translated by 3 units left,
f(x + 3) = 
g(x) = 
If the translated function is stretched vertically by a scale factor = k
New function will be,
g'(x) = 
Since a point (1, 4) passes lies on the transformed function.
g'(1) = 
4 = 2k
k = 2
Therefore, transformed function represents the translation by 3 units in the negative side of the x-axis and stretched vertically by 2 units.
Option (2) will be the answer.
X(-x^4)(-x^4)=
The answer is x^9
