So it looks like the numbers are already in numerical order, that's good. The median is simply the middle number. I shouldn't have to help you find that. If there are 2 middle numbers, take the average and that's the median.

To find mean, you need a calculator. Add up all the numbers, and then divide by 10, since there's 10 numbers total. That's the mean.

The mode is 99, because that's the most frequent number. It appears twice.

The range is the span of the data set. To find this, take the largest number (99) and minus the smallest number (1). This is the range.

Compare the values of the underlined digits.

In the first number, the "4" is in the thousands place - meaning it is 4,000 + 30,258
 In the second number, the "4" is in the ten thousands place - meaning it's
40,000 + 7,163. 
 40,000/4,000 = 10 
 The value of 40,000 in the second value is 10x greater than the value of 4,000 in the first value.

What are the zeros of the quadratic function f(x) = 2x2 + 16x – 9?
Aleksandr-060686 [28]

Answer:

The zeros of the function are -0.488 and -7.39

Step-by-step explanation:

Given the quadratic function

f(x) = 2x²+16x-9

The zeros of the function is gotten at when f(x) = 0

2x²+16x-9 = 0

Using the general equation

x = -b±√b²-4ac/2a

From the equation, a = 2, b = 16 and c= -9

x = -16±√16²-4(2)(-9)/2(2)

x = -16±√256-72/4

x = -16±√184/4

x = -16+13.56/4

x = -16+13.56/4 and -16.13.56/4

x = --2.44/5 and -29.56/4

x = -0.488 and -7.39
