Answer:

1. D) 0.113

2 C) 11

Step-by-step explanation:

1. #males that chose super strength/total males

$\frac{25}{222}$ = 0.113

2. the relative frequency can be converted to a percent which is 11.3%

given that a percent is out of 100, the expected number would be 11

A bag of marbles contains 6 bluemarbles, 2 yeloow marbles, 4 red marbles, and 1 green marble. What is the [robability of reachin

irina [24]

Answer:

The probability of picking a yellow marble is 2/13

Step-by-step explanation:

First of all, we need to know the total number of marbles that are in the bag. To do this, we will have to add up all the marble colors together.

This will give us 6 + 2 +4+ 1 = 13 marbles in total.

The next step is to find the number of yellow marbles in the bag.

We can get this from the question. There are 2 yellow marbles in the bag.

The probability of selecting a yellow marble can be obtained by dividing the number of yellow marbles by the total number of marbles in the bag

This will give us 2/13.

Therefore, the probability of picking a yellow marble is 2/13

Consider the following planes. 3x − 2y + z = 1, 2x + y − 3z = 3

prisoha [69]

Solve for any of the variables; for instance, $z$ :

$z=1-3x+2y$

$z=-\dfrac{3-2x-y}3$

Then

$1-3x+2y=-\dfrac{3-2x-y}3\implies11x-5y=6\implies\begin{cases}y=\frac{11x-6}5\\z=1-3x+\frac{22x-12}5\end{cases}$

Let $x=t$ ; then the intersection is given by the vector-valued function

$\vec r(t)=\left(t,\dfrac{11t-6}5,1-3t+\dfrac{22t-12}5\right)$

$\vec r(t)=\left(t,\dfrac{11t-6}5,\dfrac{7t-7}5\right)$
