Respuesta: Uno

La suma de la probabilidad de todos los resultados posibles de un experimento aleatorio debe ser igual a uno.

Porque algunos resultados más ocurren en cada sendero y la suma de todas las probabilidades es 100% o uno.

Espero haber ayudado, buena suerte! :)

64 = 4(p + 2) + 24 please solve step by step

Wittaler [7]

Answer:

Step-by-step explanation:

Step-1 : Multiply the coefficient of the first term by the constant 1 • -16 = -16

Step-2 : Find two factors of -16 whose sum equals the coefficient of the middle term, which is 6 .

-16 + 1 = -15

-8 + 2 = -6

-4 + 4 = 0

-2 + 8 = 6 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -2 and 8

p2 - 2p + 8p - 16

Step-4 : Add up the first 2 terms, pulling out like factors :

p • (p-2)

Add up the last 2 terms, pulling out common factors :

8 • (p-2)

Step-5 : Add up the four terms of step 4 :

(p+8) • (p-2)

Which is the desired factorization

Find the slope and y intercept 2x+3y=1,470

oksano4ka [1.4K]

First we need to put it in slope intercept form (solve for y). Then we get tex]y= -\frac{2}{3} x+490[/tex]. So the slope is-2/3 and the y intercept is 490.

beaus recipefor granola bars calls for 3 1/2 cups of oatmeal. he only have 1/6 cup scoop.how many scoops of oatmeal will he need

Stells [14]

<h2>Answer:</h2>

The number of scoops of oatmeal he will need for the recipe is:

21 scoops.

<h2>Step-by-step explanation:</h2>

It is given that:

Beaus recipe for granola bars calls for 3 1/2 cups of oatmeal.

i.e. the cups of oatmeal required is:

$3\dfrac{1}{2}\ cups=\dfrac{3\times 2+1}{2}\ cups$

i.e.

$\dfrac{7}{2}\ \text{cups\ of\ oatmeal\ is\ required}$

Also, he has:

$\dfrac{1}{6}\ \text{cup scoop}$

This means that:

$\text{Number of scoops of oatmeal he need}=\dfrac{\text{Number of cups of oatmeal}}{\text{Number of cup scoop he has}}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=\dfrac{\dfrac{7}{2}}{\dfrac{1}{6}}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=\dfrac{7\times 6}{1\times 2}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=21\ \text{scoops}$

Geometry PLS HELP due soon

egoroff_w [7]

Answer:

(3) $x = 7.5$ and $y = 51$

(4) $x = 6$

Step-by-step explanation:

Question 3

Required

Solve for x and y

We have:

$16x - 18 + 10x +3 = 180$ --- angle on a straight line

Collect like terms

$16x + 10x = 180 + 18 - 3$

$26x = 195$

Solve for x

$x = 195/26$

$x = 7.5$

Also:

$16x - 18 = 2y$ ---- opposite angles

So, we have:

$16 * 7.5 - 18 = 2y$

$120 - 18 = 2y$

$102 = 2y$

Divide by 2

$51 = y$

$y = 51$

Question 4:

Required

Solve for x

We have:

$11x - 2 + 5x - 4 = 90$ ---- angle at right-angled

Collect like terms

$11x + 5x = 90 +2 + 4$

$16x = 96$

Divide by 16

$x = 6$

Solve T=L(2+RS) for R

True [87]

Answer:

Step-by-step explanation:

I would begin by distributing the L. It will be easier in the end to do it this way. There are a couple of ways you can do this, but distribution is the easiest. After you distribute the L you have

T = 2L + LRS

Next subtract the 2L to get

T - 2L = LRS. Lastly, to isolate the R, divide away the LS to get

$\frac{T}{LS}-\frac{2L}{LS}$ = R In that second term, the L's cancel each other out, leaving us with

$\frac{T}{LS}-\frac{2}{S}$ = R
