A data set includes the following grades: 98, 94, 93, 82, 61, 80. Suppose that 61 is removed from the data. How is the median af
1 answer:
Answer:b
Step-by-step explanation:
A data with values
98,94,93,82,61,80 is given
If we arrange the number according to their values
61,80,82,93,94,98
Median of set
Now if 61 is removed then
80,82,93,94,98 are the remaining data
so New median is 93
So the median is increased by 5.5
Therefore option b is correct

<h3>What is function?</h3>
Function is an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
According to the question,
The given function is
Here f(x) = -12
Substitute f(x) and solve for x
By subtracting 3 on both sides
By dividing -5 on both sides
We get absolute values for the function.
By subtracting 1 on both sides
Therefore, the values of x are 2 and - 4 of the given function f (x) =-5|x+1| +3

Answer:
11.6 ft
Step-by-step explanation:
I attached a diagram for you to easily visualize this problem.
To solve this problem, you would use the pythagorean theorem. The 12-ft ladder is the hypotenuse and the 3 ft from the barn is one of the side legs. You want to find the length of the "other side leg", or the height of the barn.
Substitute 3, 12, and x into the pythagorean theorem like so.
a^2 + b^2 = c^2
3^2 + x^2 = 12^2
Evaluate the exponents.
9 + x^2 = 144
Subtract 9 from both sides.
x^2 = 135
Square root both sides.
x = 11.618
Round this to the nearest tenth: 11.6 feet.
