The sequence is

740, 707.60,675.20,642.80,...

Here first term is 740, and common difference, d is

707.60-740 = -32.40

Now we use the formula of nth term, which is

a_{n} = a+(n-1)d

Substituting the values of a,n and d, we will get

=740+(n-1)(-32.40), 23 months

Correct option is the second option .

fomenos

Answer:

0.37

Step-by-step explanation:

we have given that emails arrives at the server at the rate of 10 per hour means \frac{10}{60}=0.166  per minute

we have to find the probability that the time difference between the two email is more than 2 minute

so probability P\left ( X> 2 \right )=e^{-2\lambda }=e^{-2\times 0.166}=0.7166

Write the equation of the line that passes through the points (7,-6) and (0,2). Put
Alex

Answer:

y+6=\frac{-8}{7} (x-7)

Step-by-step explanation:

To find the slope of the equation use \frac{y_2-y_1}{x_2-x_1}.

So, \frac{-6-2}{7-0} = \frac{-8}{7}. Now we can use our slope and any of the two points to write in point-slope form, which is y-y_1=m(x-x_1). Using the point (7,-6), the formula will give y+6=\frac{-8}{7} (x-7).

To check, you can plug in this equation and the points into a calculator to graph. The line passes through both points.
