(a+b)/2 = 25
(a*b)^0.5 = 20
a = 400/b
b^2-50b+400=0
b=40, b=15
a=15, a=40

In mathematics how do you work out the range?
The Range is the distance on the number line that the smallest number is from the biggest number, in sbsolute value. Basically, to find it using math, you would subtract the smallest number in the series of numbers from the largest number in the same series.
What is the absolute value of the product of all the integers from -6 to 3?
0any number, or series of numbers, multiplied together (product) with zero equals zero; and the absolute value of zero is zero.
The mean of 100 numerical observations is 35.73 What is the value of the sum of all 100 numbers?
The mean of a series is equal to the sum divided by the number of items in the series. So, mean = sum/number, which means the sum is equal to the mean times the number. In this case, the sum is 3573.
Can an numbers absolute value be zero?
The only number whose absolute value is zero is zero. This is because a number's absolute value is its distance from zero on the number line.
How many numbers have an absolute value of five fourths?
Two (assuming you are talking about real numbers). In general, for any given positive number, there will be two real numbers whose absolute value is that given number. In the case of complex numbers, the answer is "infinitely many" - all the numbers on a circle centered on the origin, with that radius, have that absolute value.
What is a number?
The Fibonacci numbers is a series of numbers that are found in nature and other things. The series goes 0,1,1,2,3,5,8,13,21 and so on. You just add the last two numbers in the series. 0+1=1, 1+1=2, 2+1=3, and so on.

How can you estimate the value of an irrational number?
There are different methods for estimating irrational numbers. For numbers like pi or e, there are infinite series which can be used to calculate their value to the required degree of accuracy. There are numerical methods - such as the Newton-Raphson iteration - for estimating roots of numbers.

0any number, or series of numbers, multiplied together (product) with zero equals zero; and the absolute value of zero is zero.
What do the numbers stand for on a BMW car?
The first number stands for the Series 1,3,5,6,7- which the higher the series the higher the value and basicly more gadgets, the number following that is the sie engine 2.5 liter 2.8 liter so a BMW 328i is 3 series-2.8liter

No added value. G7 is just a plate number. Look at some other bills and you'll find that they all have similar numbers on them.

The mean of a series is equal to the sum divided by the number of items in the series. So, mean = sum/number, which means the sum is equal to the mean times the number. In this case, the sum is 3573.
The difference of the absolute value of two numbers is positive?
Yes. The absolute value of two numbers is ALWAYS positive. This is because absolute value means "the number of spaces a number is from zero on a number line.
What negative numbers are less than positive numbers. Does this mean that the absolute value of a negative number must be less than the absolute value of a positive number Explain?
No it is not true. The absolute value of a number is simply the value of the number with a positive sign.
How do you add two numbers with opposite signs?
Subtract the absolute value of the smaller number from the absolute value of the larger number. The answer will have the sign of the larger numbers.
How do you write C program to print a Series of Odd Numbers and Even Numbers.?
Generate a random number in half the range you are interested in. If generating odd values, subtract 1 from the upper bound of the range. That is, if the range is 0 to 100, then generate a random number in the range 0 to 50 for even numbers and 0 to 49 for odd numbers. Double the generated number to obtain the even value, or double it and add 1 to obtain the odd value.
