Answer 1

Answer:

Answer:

The average number of pizzas sold in one night if no coupons are issued is 43.

Step-by-step explanation:

In the scatter plot the average number of pizzas sold is represented on x and number of coupons issued is represented on y.

The trend line of this linear model is $y = 3.4x + 43$

So, when no coupons are issued then the value of x becomes 0, then putting the value of x in the equation,

$\Rightarrow y=3.4(0)+43$

$\Rightarrow y=0+43$

$\Rightarrow y=43$

Therefore, the average number of pizzas sold in one night if no coupons are issued is 43.

Answer 2

Answer:

Answer:

The correct answer option C.

Step-by-step explanation:

Let x be the number of coupons issued.

Let y be the number of the pizzas sold.

The given equation:

$y=3.4x+43$

This given equation of an straight line.

Number of pizzas when no coupons were issued.

$y=3.4x+43=3.4* 0+43=43$

43 number of pizzas were sold in one night.

Hence, the correct answer option C.

Answer:

a) YES. Repeating decimal

b) YES. Repeating decimal

c) NO. Decimal neither terminates nor repeats

d) YES. Terminating decimal

Step-by-step explanation:

Any rational number can be written as a fraction, that is, a division of integers.

a) The number $\overline{0.54}$ has a repetitive period of 54. It can be expressed as a fraction because its decimal are repeating forever

b) The number 0.16666... (expressed as a repeating 6) can also be converted to a fraction because it's a repeating decimal

c) The number 0.5473... cannot be expressed as a fraction because the ellipsis (...) means the decimals continue with no limit and no pattern can be found (no repetitive decimal)

d) The number 0.378 can be easily expressed as a fraction because it has a finite number of decimals (no ellipsis) or a terminating decimal
