11. Let's assume that Ryan has x stamps, so Charlie has 5x stamps.

Set up the equation:
x + 5x = 1,608
6x = 1,608
x= 268

So Ryan has 268 stamps, and Charlie has 5*268 = 1340 stamps

12. You already calculated how many monitors he sold which is 33.

Multiply : 185 * 33 = $6105

(you might have done something wrong when multiplying :) )

estamos construyendo una carretera que enlace los puntos a = 12 ,21 y b =(17,23) otro punto se encuentra en c =(3,9) es posible

Nadusha1986 [10]

Answer:

is not possible

Step-by-step explanation:

<u><em>The question in English is</em></u>

we are building a road that links the points a = (12 ,21) and b =(17,23) another point is in c =(3,9) it is possible that a single road allows to join these three points?

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

step 1

Find the slope ab

we have

a = (12 ,21) and b =(17,23)

substitute

$m=\frac{23-21}{17-12}$

$m=\frac{2}{5}$

step 2

Find the slope ac

we have

a = (12 ,21) and c =(3,9)

substitute

$m=\frac{9-21}{3-12}$

$m=\frac{-12}{-9}$

simplify

$m=\frac{4}{3}$

step 3

Compare slopes ab and ac

The slopes are different

That means ----> is not possible that a single road allows to join these three points

The probability distribution function for the discrete random variable where x is equal to the number of red lights drivers typi

Ivahew [28]

Using probability concepts, it is found that:

a) The missing value is 0.04.

b) The mean is of 0.37.

The distribution is given by:

$P(X = 0) = 0.76$

$P(X = 1) = 0.15$

$P(X = 2) = 0.05$

$P(X = 3) = x$

Item a:

The sum of <u>all the probabilities has to be 1</u>, that is:

$\sum_{i = 0}^{3} P(X = i) = 1$

Thus:

$0.76 + 0.15 + 0.05 + x = 1$

$0.96 + x = 1$

$x = 0.04$

The missing value is 0.04.

Item b:

The mean is given by the <u>sum of each outcome multiplied by it's probability</u>, thus:

$E(X) = 0(0.76) + 1(0.15) + 2(0.05) + 3(0.04) = 0.37$

The mean is of 0.37.

Identify the initial amount a and the growth or decay factor b in the exponential function. y = 0.01025^x

Nastasia [14]

Answer:

The initial amount a = 1

The growth or decay factor = 0.01025

Step-by-step explanation:

The exponential function.

y = 0.01025^x

The initial amount a = 1

The growth or decay factor = 0.01025

The exponential equation can be rewritten as Y = 1(0.01025)^x
