Answer:  x = 400 MPH    x+60 = 460 MPH

Step-by-step explanation:

(Distance = (Rate)(Time)

Let x = speed of the LA bound plane

Then, x+60 = speed of NYC bound plane

Sum of distances = 2464

3.4x + 2.4(x+60) = 2464

         5.8x + 144 = 2464

                  5.8x = 2320

                      x = 400 MPH    x+60 = 460 MPH

Sonja [21]

Answer:

b) Both 1,004 and 251 are greater than 10.

Step-by-step explanation:

p = 0.80

n = 1255

In order to use CLT the distribution of \hat{p} should have np and n(1-p) greater than 10.

np = 1255*0.80

np = 1004

n(1-p) = 1255*0.20

n(1-p) = 251.00

Since Both 1004 and 251 are greater than 10,

<h3>The height of a building that is 25.40 meters tall is 9.910 cm</h3>

<em><u>Solution:</u></em>

Given that,

If you want a car that is 5.126 meters long to be represented by a matchbox car of length 2.000 cm

Therefore,

5.126 meters is represented as 2 cm

What would be the height of a building that is 25.40 meters tall ?

25.40 meters = ? cm

Let "x" be the height of a building that is 25.40 meters tall

From given,

5.126 meters = 2 cm

25.40 meters = x cm

This forms a proportion and we can solve the sum by cross multiplying

5.126 \times x = 25.40 \times 2\\\\x = \frac{50.8}{5.126}\\\\x = 9.910

Thus height of a building that is 25.40 meters tall is 9.910 cm
