Up to 2 integers can have the same absolute value (a number and its opposite).

For example, 2 and -2 have the same absolute value. 5 and -5 also have the same absolute value.

Answer:

Only two integers can have the same absolute value.

Step-by-step explanation:

Consider the provided information.

We need to find the number of different integers which gives same absolute value.

Absolute value is the number value, regardless of the sign whether it is negative or positive. On number line it is the distance between number and 0.

As we know integers can both positive and negative, and absolute value always remains positive.

If we take any integer let say -10 the absolute value of the number will be 10.

Similarly if we take 10 then the absolute value of the number will be 10.

Thus, the number 10 and -10 have same absolute value.

Hence, only two integers can have the same absolute value.

A discrete variable is a type of variable which contains a finite number of values. It usually takes its values from the set of whole numbers.

From the random variable described, the random variable that is descrete is "You measure the maximum heart rate in beats per minute".

This is because, heart rate cannot be partitioned it only takes counting number values. You either have 1 beat per minutes, 2 or 3 and so on beats per minute. But you cannot have 2.5 or 3.8 and so on beats per minute.
So heart rate cannot take decimal or fractional values and hence, it is a discrete random variable.

Sixty-five campers arrive. Nine go home early. If 8 people sleep in 1 tent, how many tents will the campers need?

allsm [11]

65-9=56

56 divided by 8 is 7

So they will need 7 tents

Evaluate the series shown. Then write an equivalent series using summation notation such that the lower index starts at 0.

Vitek1552 [10]

The summation indicates the sum from n = 1 to n = 3 of the expression 2(n+5).

2 (n+5) = 2n + 10

2n + 10 denotes an Arithmetic Series, with a common difference of two and first term as 12.

For n =1, it equals 12
For n = 2, it equals 14
For n = 3, it equals 16

So the sum from n=1 to n=3 will be 12 + 14 + 16 = 42

Sum of an Arithmetic Series can also be written as:

$S_{n} = \frac{n}{2}(2a_{1} +(n-1)d)$

Using the value of a₁ and d, we can simplify the expression as:

$S_{n} = \frac{n}{2} (24+2(n-1)) \\ \\ 
 S_{n} =n (12+(n-1))\\ \\ 
 S_{n} =n (11+n)$

This expression is equivalent to the given expression and will yield the same result.

For n=3, we get the sum as:

S₃ = 3(11+3) = 42
