Answer:

Step-by-step explanation:

Note that the horizontal axis notes the years since 2000. This means that each increase in the x axis increases the year by 1. Thus, it means that at x=1, it is 2001, at x=2, it is 2002. In other words, in 2016, x=16.

We can just put this number into the equation:

y=1.5(16)-1

y=24-1

y=23

Answer:

24.5

Step-by-step explanation:

Year 2000 would be 1, so year 2016 would be 17

Your equation is 1.5x - 1, and since we have x = 17, we simply plug it in:

1.5(17) - 1

25.5 - 1

24.5 is our estimated population using the line of best fit.

Katy makes 48 cookies an hour. If she has 24 alr, how long would it take her to make 120?

rosijanka [135]

Question:

Katy makes 48 cookies an hour. If she has 24 already, how long would it take her to make 120?

Answer:

It takes 2.5 hours for Katy to make 120 cookies

Step-by-step explanation:

Given:

Time taken to make 48 cookies = 1 hour

To Find:

Time taken to make 120 cookies = ?

Solution:

Time taken to make 48 cookies = i hour

So now time taken to make 1 cookie = $\frac{1}{48} hour$

So time taken to make 120 cookies

= Number of cookies X time taken to make one cookie

=> $120 \times \frac{1}{48}$

=> $\frac{120}{48}$

=> 2.5 hours

Answer:

Area of the Rectangle is (length×breadth)

$5 {x}^{5} {y}^{3} \times {(7 {x}^{3}y) }^{4} = 5 {x}^{5} {y}^{3} \times 2401 {x}^{12} {y}^{4} \\ = 12005 {x}^{17} {y}^{7}$

Third option is the right answer.

If p and q are non-zero rational numbers, and s and t are irrational numbers, select all of the statements that are always false

Svetllana [295]

Answer:

The false choices are A, C, and E

Step-by-step explanation:

Let's make an example:

p=1

q=2

s=sqrt(3)

t=sqrt(6)

Since pq=1*2=2, the answer is rational and A is false.

Since pt=1*sqrt(6)=sqrt(6), the answer is irrational and B is true.

Since p/q=1/2=0.5, the answer is rational and C is false.

Since st=sqrt(3)*sqrt(6)=sqrt(18), the answer is irrational and D is true.

Since s/t=sqrt(3)/sqrt(6)=sqrt(1/2), the answer is irrational and E is false.
