IQR = 40
1) Put the numbers in order: 40, 45, 50, 60, 60, 75, 90, 90, 120
2) Find the median: Median is 60 (the 2nd one)
3) Place parentheses around the numbers above and below the median. For easy identification of Q1 and Q3. (40, 45, 50, 60,) 60, (75, 90, 90, 120)
4) Find the Q1 and Q3. Q1 = median of the lower half of the data; Q3 = median of the higher half of the data. Q1 and Q3 have even sets so its median cannot be defined.
5) Had both sets contain odd sets, the median of Q1 is subtracted from the median of Q3 to get the IQR.
We can then use the Alternative definition of IQR.
IQR is the difference between the largest and smallest values in the middle 50% of a set data.
40, 45, 50, 60, 60, 75, 90, 90, 120
Middle 50% is 50, 60, 60, 75, 90; IQR = Largest value - smallest value;
IQR = 90 - 50 = 40
Answer:
<h2>C</h2>
Step-by-step explanation:
To determine a function rule, look at the table. Input the x and y value from one column into the function to see if it is correct.
<h3>Function a: y = 10 - 2x</h3>
Input values
22 = 10 - 2(6)
22 = 10 - 12
22 ≠ -2 ❌
As we can see, function a gives us a false statement, so a is incorrect.
<h3>Function b: y = 2 - 10x</h3>
Input values
22 = 2 - 10(6)
22 = 2 - 60
22 ≠ -58 ❌
We once again get a false answer, so b is also not correct.
<h3>Function c: y = 10 + 2x</h3>
Input values
22 = 10 + 2(6)
22 = 22 ✔
Finally, we get a true statement, so option c is correct.
<h3>Function d: y = 2 + 10x</h3>
Just to check that option c is correct, we need to prove that d is incorrect.
Input values
22 = 2 + 60
22 ≠ 62 ❌
This is also wrong, so that proves that c is correct.
I'm always happy to help :)
The volume of the triangular prism is 66 cubic inches.
In order for us to know the volume of the triangular pyramid, first we need to know the ratio of the volume of triangular prism and the volume of the triangular pyramid.
Volume of the pyramid = 1/3 * volume of the prism.
Volume of the pyramid = 1 / 3 * 66
<span>Volume of the pyramid = 22 cubic inches.
</span>
So the volume of the triangular pyramid is 22 cubic inches.
Answer:
is the question g inverse ??
i have answered for g inversed
g(x)=3x-7
y=3x-7
interchanging the value of x and y
x=3y-7
(x+7)/3=y
g-1(x)=(x+7)/3
so g-1(2)=(2+7)/3
=9/3
=3
therefore 3 is the answer
