It takes a jet 2 hours to fly 1100 miles at this rate. How far does it fly in 8 hours

aivan3 [116]

Answer: The jet will fly 4400miles in 8 hours.

Step-by-step explanation:

Let the missing value be represented by x

2 hours = 1100 miles

8 hours = x

We cross multiply:

2x = 1100 x 8

2x = 8800

Divide both sides by 2 to get the value of x

x = 8800/2

x = 4400

Therefore, the jet will fly 4400miles in 8 hours.

Suppose the path of a baseball follows the path graphed by the quadratic function ƒ(d) = –0.6d2 + 5.4d + 0.8 where d is the hori

Vinil7 [7]

Answer:

Domain is all real numbers

Range is

$y\le 12.95$

Step-by-step explanation:

The given function is

$f(d)=-0.6d^2+5.4d+0.8$

This is a maximum quadratic function therefore the domain is all real numbers.

Let us complete the square to find the vertex.

$f(d)=-0.6(d^2-9d)+0.8$

$f(d)=-0.6(d^2+9d)+-0.6(\frac{9}{2})^2- -0.6(\frac{9}{2})^2+ 0.8$

$f(d)=-0.6(d-\frac{9}{2})^2+\frac{243}{20}+ 0.8$

$f(d)=-0.6(d-\frac{9}{2})^2+\frac{259}{20}$

Therefore the range is

$y\le \frac{259}{20}$

$y\le 12.95$

No

Step-by-step explanation:

Here we are taking only one measurement: the height of one person. Strictly speaking, this is NOT a statistical question.

"List the heights of a sample of 50 first-graders" would definitely be a stat. question.
