The answer is 12.5 seconds.

48/5 = 120/x
x = 2.5
2.5 * 5 = 12.5

Answer:

12,5

Step-by-step explanation:

First, you need to find how many kilobytes do you download every seconds.

You simply divide 48 kilobyte / 5 seconds and you get 9,6 kB/s.

Now you know that your download speed is this you can find the amount of time needed for downloading 120 kilobytes.

You simply divide \frac{120 kilobytes}{9,6 kilobytes/s} = 12.5 s.

12,5 seconds.

Jon is launching rockets in an open field. The path of the rocket can be modeled by the quadratic function h(t) = -16t^2 + 96t,
IrinaVladis [17]
It will reach 80 feet for the second time after 5 seconds.

We set the equation equal to 80 feet:
80= -16t² + 96t

When solving quadratics, we want it equal to 0, so we subtract 80 from both sides:
80-80= -16t² + 96t - 80
0= -16t² + 96t - 80

We use the quadratic formula to solve:
t=\frac{-96\pm \sqrt{96^2-4(-16)(-80)}}{2(-16)}
\\
\\t=\frac{-96\pm \sqrt{9216-5120}}{-32}
\\
\\t=\frac{-96\pm \sqrt{4096}}{-32}
\\
\\t=\frac{-96\pm 64}{-32}
\\
\\t=\frac{-96+64}{-32} \text{ or } 0=\frac{-96-64}{-32}
\\
\\t=1 \text{ or } t=5

slope = y₂ - y₁/x₂-x₁

= 18- 13 / 8-11

= 5 / - 3

Given that the data distribution is approximately normal with the minimum value of 15 and the maximum value of 98 a) Estimate th
andrew11 [14]

Answer:

a) Mean, median, mode = 56.5

b) S = 20.75

Step-by-step explanation:

Normally distributed data have the same value for the mean, median and mode. This value is the addition of the maximum value by the minimum, divided by 2.

Also, the standard deviation in a normally distributed sample can be approximated by the following formula:

S = \frac{max - min}{4}

So

a) Estimate the values of Mean, Median, and Mode.

Highest value = 98

Minimum value = 15

\mu = \frac{98 + 15}{2} = 56.5

b) Estimate the value of the standard deviation of these data

Max = 98

Min = 15

So

S = \frac{max - min}{4}

S = \frac{98 - 15}{4}

S = 20.75
