Find P (Sophomore | Boy)

Mandarinka [93]

Answer:

$\textbf{P} \textbf{(Sophomore}\hspace{1mm} | \hspace{1mm} \textbf{Boy)} \hspace{1mm}\textbf{=} \hspace{1mm} \frac{\textbf{5}}{\textbf{12}} $$

Step-by-step explanation:

We are asked to find the probability of picking a Sophomore who is a boy.

There are 5 Sophomores who are boys out of total boys.

$\textbf{P(A} | \textbf{B)} \hspace{1mm} \textbf{=} \hspace{1mm} \frac{\textbf{P(A and B)}}{\textbf{P(B)}}$

$\implies P(Sophomore | Boy) = \frac{P(Sophomore \& Boy)}{P(Boys)}$

$= \frac{5}{12}$

Hence, the answer.

How many liters fit in a cube that is 30 centimeters on a side

astra-53 [7]

Answer:

$27\ liters$

Step-by-step explanation:

step 1

Find the volume of the cube

The volume of a cube is

$V=b^{3}$

where

b is the length side of the cube

we have

$b=30\ cm$

substitute

$V=(30)^{3}$

$V=27,000\ cm^{3}$

step 2

Convert cm^3 to liters

Remember that

$1\ liter=1,000\ cm^3$

$27,000\ cm^{3}=27,000/1,000=27\ liters$

In the Changing Dimensions of 3D Figures

den301095 [7]

Answer:factor of 9

Step-by-step explanation:

Given

prism were changed by a scale factor of 3

Suppose prism is rectangular in shape

So surface are is $S.A.=2(lw+wb+lb)$

Where l=length

w=width

b=breadth

So new length,breadth and width is

$l'=3l$

$w'=3w$

$b'=3b$

$S.A.=2(3\times 3lw+3\times 3wb+3\times 3lb)$

$S.A.=2\times 3^2(lw+wb+lb)$

$S.A.=3^2\times 2(lw+wb+lb)$

So new surface area would change by a factor of 9

Simplify the expression. What classification describes the resulting polynomial? (3x^2-11x-4)-(2x^2-x-6)

Gnoma [55]

The expression can be simplified to a polynomial of degree 2.

$x^2 - 10x + 2$

<h3>How to simplify the expression?</h3>

Here we have the expression:

$(3x^2 -11x - 4) - (2x^2 - x - 6)$

We can directly simplify this by taking the variable as common factor:

$(3 - 2)*x^2 + (-11 + 1)*x + (-4 + 6)\\\\x^2 - 10x + 2$

This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.
