Answer:

500.5

Step-by-step explanation:

The average of a set of numbers is the sum of the numbers divided by the number of numbers.

The sum of all whole number form 1 to n is n(n + 1)/2.

The sum of all whole numbers from 1 to 1000 is

1000(1000 + 1)/2 = 1000(1001)/2 = 500,500

The average is the sum of the numbers divided by the number of numbers.

average = 500,500/1000 = 500.5

Ivenika [448]

Answer:

7 , 8 , 9

Step-by-step explanation:

Assume three consecutive number are,

x , (x+1) , (x+2)

Multiplied by 2 ,3 and 4 respectively

2x , 3(x + 1) , 4(x + 2)

Sum of all = 74

So,

2x + 3(x + 1) + 4(x + 2) = 74

2x + 3x + 3 + 4x + 8 = 74

9x + 11 = 74

9x = 63

x = 7

So,

x , (x+1) , (x+2)

7 , (7+1) , (7+2)

7 , 8 , 9

Which of the following are characteristics of the graph of the absolute value parent function?
lora16 [44]

The graph of an absolute value parent function is a pair of rays in quadrant 1 & 2, as shown in the graph.

The absolute value function is

f(x) = |x| or y = |x|

We also know that the absolute function can be wriiten as

y = |x|

=> y = x    or   y = -x

Comparing with y = mx + c

We get

m = 1   or   m=-1    and c = 0

c = 0 implies that the line passes through the origin.

Hence the slopes shall be -1, 1 & the line passes through the origin.

Option A, B & D are the right answers.
