As the Earth revolves around the sun, it travels at a speed of approximately 18

zzz [600]

So if the earth goes 18 miles per second you would multiply 18 and 60 since 60 seconds are in a minute. And that is 1,080 miles in a minute then times that by 5 and your answer is 5,400 miles in 5 minutes.

F(t)=10t2+5t+1 . Find the value of t for which the tangent line to the graph of f(t) has slope 1.

kozerog [31]

$\bf f(t)=10t^2+5t+1\implies \stackrel{\textit{slope of tangent}}{\cfrac{df}{dt}}=20t+5\implies 1=20t+5
\\\\\\
-4=20t\implies -\cfrac{4}{20}=t\implies -\cfrac{1}{5}=t$

A normal curve with a mean of 500 and a standard deviation of 100 is shown. Shade the region under the curve within one standard

N76 [4]

Answer:

And for this case we want to find how much of the data within the shaded region given in the figure attached.

And we can use the zscore formula given by:

$z = \frac{X -\mu}{\sigma}$

And if we find the z score for the limits we got:

$z = \frac{400-500}{100}=-1$

$z = \frac{600-500}{100}= 1$

And we want to find this probability using the normal standard distribution or excel:

$P(-1$

So we would expect about 68.2 % of the data within one deviation from the mean

Step-by-step explanation:

For this case we know that the variable of interest let's say x follows a normal distribution with the following parameters:

$X \sim N(\mu = 500, \sigma =100)$

And for this case we want to find how much of the data within the shaded region given in the figure attached.

And we can use the zscore formula given by:

$z = \frac{X -\mu}{\sigma}$

And if we find the z score for the limits we got:

$z = \frac{400-500}{100}=-1$

$z = \frac{600-500}{100}= 1$

And we want to find this probability using the normal standard distribution or excel:

$P(-1$

So we would expect about 68.2 % of the data within one deviation from the mean
