8 times 10 to the power of 5 is how many as great as 8 times 10 to the power of -1

10^6

Step-by-step explanation:

● 8×10^5

● 8 × 10^(-1)

Divide the the first number by the second one

● 8×10^5/ 8×10^(-1) = 10^(5-(-1)) = 10^6

So 8×10^5 is greater 10^6 times than 8×10^(-1)

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
