No, I don't aree with him because the formula for the median is formula is {(n + 1) ÷ 2}th, where “n” is the number of items in the set and “th” just means the (n)th number. To find the median, first order the numbers from smallest to largest. Then find the middle number.
so it's 1,4,7,8 and 13 so the median is 7
so we do not agree with him

Answer:
x^4- x^3- 4x^2-3
Step-by-step explanation:
Given
f(x)= x^4- x^2+9
And
g(x)= x^(3 )+ 3x^2+12
We have to find
(f-g)(x)= ?
The operations on functions are as easy as the operations on numbers or polynomials.
We have to subtract the functions to find the above mentioned operation.
=(f-g)(x)=f(x)-g(x)
(f-g)(x)=[x^4- x^2+9]-[x^(3 )+ 3x^2+12]
The minus will change the signs of function g.
= x^4- x^2+9- x^(3 )- 3x^2-12
= x^4- x^3- x^2- 3x^2+9-12
=x^4- x^3- 4x^2-3
Given :
There are 50 people at the city swim park today. Everyone in the park was wearing swim suits or sunglasses, some people had both.
38 have swim suits on and 25 have sunglasses.
To Find :
How many people had swim suits on but not sunglasses.
Solution :
Let, A refer swim suits and B refer sunglasses.
∞∪∩
A ∪ B = 50
A = 38
B = 25
We need to find, A - (A ∩ B) .
We know,
(A ∩ B) = A + B - (A ∪ B)
(A ∩ B) = 38 + 25 - 50
(A ∩ B) = 13
So, A - (A ∩ B) = 38 - 13 = 25
Therefore, number of people with swim suits on but not sunglasses are 25.
Answer:
The quotient is: x-7
The remainder is: -2
Step-by-step explanation:
We need to divide (x^2 - 13x +40) divided by (x- 6)
The quotient is: x-7
The remainder is: -2
The division is shown in the figure attached
Answer:
Match the stem and leaf plot to the correct set of data.
The set of data that can be created from the given stem and leaf plot using the key 1 | 6 means 1.6 is:
1.5, 1.5, 1.6, 2.1, 2.1, 2.1, 3.5, 3.6
From the given options, the option C) is correct.
Hence, the option C) 1.5, 1.5, 1.6, 2.1, 2.1, 2.1, 3.5, 3.6 is the correct data set for the given stem and leaf plot
