Answer:

Step-by-step explanation:

10 miles/65 minutes

65 minutes/10 miles

you need to find minutes per mile

Divide (Total number of Minutes) by (Total number of miles)

PLEASE ANSWER THIS MATH QUESTION FOR THOSE MATH LOVERS :)

viva [34]

Remark

The general formula for these types of questions is

(x1 + k(x2 - x1) ) , (y1 + k(y2 - y1))

<u>Problem 1 -- Point G</u>

Givens

(x1,y1) is the starting point which in this case is (-3, -3)

(x2,y2) is the ending point which in this case is (6 , -3)

k = 1/4

Sub and solve

(-3 + 1/4(6 - - 3), - 3+ 1/4(- 3 - - 3)

(-3 + 1/4(9) , - 3 + 1/4 (-3 + 3)

(-3 + 9/4, -3 + 1/4(0) )

(-12/4 + 9/4 , -3)

(-3/4 , - 3) Answer

<u>Problem 2 Point F Much harder</u>

Givens

(x1,y1) = (-3 , -1)

(x2,y2) = (6, - 3)

k = 3/4

Sub and solve

(-3 + 3/4(6 - - 3) , -1 + 3/4(-3 - - 1) )

(-3 + 3/4(9) , - 1 + 3/4(-2) )

(-3 + 27/4 , -1 - 6/4 )

(-12/4 + 27/4, -4/4 - 6/4)

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 2,6, 18,... Find the 8th term.

Andrei [34K]

Answer:

4,374

Explanation:

Given the sequence: 2, 6, 18, ...

If we study the pattern we observe that:

$\begin{gathered} \frac{6}{2}=3 \\ \frac{18}{6}=3 \end{gathered}$

This is a geometric sequence with:

• The first term, a=2

• Common Ratio, r=3

The nth term of a geometric sequence is obtained using the formula:

$U_n=ar^{n-1}$

Therefore, the 8th term will be:

$\begin{gathered} U_8=2\times3^{8-1} \\ =2\times3^7 \\ =4374 \end{gathered}$

The 8th term of the sequence is 4,374.

The random variable x is the number of occurrences of an event over an interval of ten minutes. It can be assumed that the proba

padilas [110]

Answer:

A Poisson distribution, with λ=5.3

$P(x) = \frac{\lambda^{x} *e^{-\lambda}}{x!}$

Step-by-step explanation:

For this type of random variables, a Poisson distribution is the most adecuate.

If the number of occurrences in ten minutes is 5.3, we can define the parameter λ=5.3 and the probability function as:

$P(x) = \frac{\lambda^{x} *e^{-\lambda}}{x!} =\frac{5.3^{x} *e^{-5.3}}{x!} \approx\frac{0.005*5.3^{x}}{x!}$
