The sample space of picking a 2

Alchen [17]

Answer:

$Pr = \frac{1}{15}$

Step-by-step explanation:

Given

See attachment for sample space

Required

$P(1\ Y\ and\ 1\ P)$

From the attached sample space, we have:

$n(S) =30$ ---- total outcomes

$n(PY) = 2$ --- outcomes with 1 Y and 1 P = 2 i.e. (P,Y) and (Y,P)

So, the required probability is:

$Pr = \frac{n(PY)}{n(S)}$

$Pr = \frac{2}{30}$

$Pr = \frac{1}{15}$

<em>The error is that; Carlos omitted the numerator</em>

The only items in a container A are 150 pencils and 725 pens. The ratio of the number of pencils to the number of pens in contai

Norma-Jean [14]

Answer:

Option E) 8000

Step-by-step explanation:

It is given in the question that the number of pencils and pens in a container A are 150 and 725.

Let the number of pens and pencils in container B are x and y.

As per statement " Ratio of the number of pencils to the number of pens is 2:3"

Equation will be $\frac{x}{y}=\frac{2}{3}$

Or $x=\frac{2}{3}y$ ------(1)

Second statement says "If all pens and pencils of container B are placed in container A then ratio of pencils and pens would be 3:5"

Equation will be $\frac{x+150}{y+725}=\frac{3}{5}$

5(x + 150) = 3(y + 725) [By cross multiplication]

5x + 750 = 3y + 2175

5x - 3y = 2175 - 750

5x - 3y = 1425 ------(2)

Now we put $x=\frac{2}{3}y$

$5(\frac{2y}{3})-3y=1425$

$\frac{10y}{3}-3y=1425$

$\frac{10y-9y}{3}=1425$

$\frac{y}{3}=1425$

y = 3×1425

y = 4275

Now we put y = 4275 in equation 1

$x=\frac{2}{3}(4275)$

x = 2850

Now (x + y) = 2850 + 4275

= 7125

Now Total number of pen and pencils in container A and container B

= 150 + 725 + 7125

= 8000

Therefore, Option E) is the answer

Johnny and Cage are working together to mold figurines for a craft fair. They already have 8 figurines which were left from the

alukav5142 [94]

Answer:

See Explanation

Step-by-step explanation:

Given

$Initial = 8$

$Increment = 3$ (every hour)

Required

Explain why it is linear

First, we need to determine the equation that represents the scenario

Let x be the number of hours worked and y be the number of figurines at x hours.

The equation is determined as follows:

$y = Initial\ Figurines + Increment * x$

This gives:

$y = 8 + 3 * x$

$y = 8 + 3x$

Reorder

$y = 3x + 8$

A linear equation is of the form

$y = mx + b$

By comparison,

$y = mx + b$ is equivalent to $y = 3x + 8$

<em>Hence, we can conclude that the situation is linear</em>
