What is the sum of the first 150 odd positive integers?
Show work please!!!

11325.

Step-by-step explanation:

Step 1: address the formula, input parameters & values.

Input parameters & values:

The number series 1, 2, 3, 4, . . . . , 149, 150.

The first term a = 1

The common difference d = 1

Total number of terms n = 150

Step 2: apply the input parameter values in the formula

Sum = n/2 x (a + Tn)

= 150/2 x (1 + 150)

= 22650/2

1 + 2 + 3 + 4 + . . . . + 149 + 150 = 11325

Therefore, 11325 is the sum of positive integers up to 150.

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
