What is the sum of the first 100 even natural numbers?

The sum of the first 100 even natural numbers = 10, 100

Step-by-step explanation:

We can compute the sum of the first 100 even natural numbers using the formula    

Replacing n with the number of terms i.e. 100

                          ∵  

As we have to look for even number, just multiply them by

Therefore, the sum of the first 100 even natural numbers = 10, 100

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold
