What is the probability of rolling a die and having it land on a factor of 30?

Daniel [21]

Answer:

So, since there is an equal chance to roll any number on a six sided die, that means the chance of rolling any one number is one out of 6 or 1/6. You can see that with a diagram. Now, rolling two different numbers in a specific order you can tell with a diagram is 1/36.

A student's cost for last semester at her community college was $2800. She spent $308 of that on books. What percent of last sem

Rudik [331]

You want to divide the cost of the books by the total costs.

308/2800 = 0.11

You then need to convert 0.11 to a percent: 0.11 = 11%

Therefore, 11% of her costs last semester were spent on books.

That’s too much!

Use the same coordinate plane to draw the graphs of the functions. Y=kx-2 if k=1, 0.4,-1

mario62 [17]

Graphs can be used to represent functions.

See attachment for the graphs of: <em>y =x - 2, y = 0.4x - 2, y =-x - 2</em>

The function is given as: $\mathbf{y = kx - 2}$

When k = 1,

We have:

$\mathbf{y = 1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = x - 2}$

So, the equation is: $\mathbf{y = x - 2}$ when k = 1

When k = 0.4,

We have:

$\mathbf{y = 0.4\times x - 2}$ ----- substitution property of equations

$\mathbf{y = 0.4x - 2}$

So, the equation is: $\mathbf{y = 0.4x - 2}$ when k = 0.4

When k = -1,

We have:

$\mathbf{y = -1\times x - 2}$ ----- substitution property of equations

$\mathbf{y = -x - 2}$

So, the equation is: $\mathbf{y = -x - 2}$ when k = -1

See attachment for the graphs of: $\mathbf{y = x - 2}$ , $\mathbf{y = 0.4x - 2}$ and $\mathbf{y = -x - 2}$

A jar contains 38 red marbles numbered 1 to 38 and 38 blue marbles numbered 1 to 38 a marble is drawn at random from the jar

liq [111]

Answer:

$P(Red) = 0.50$ '

$P(Odd) = 0.50\\$

Step-by-step explanation:

Given

$Red = 38$

$Blue = 38$

Required (Missing part of the question)

(a) The marble is red. (b) The marble is odd-numbered

Solving (a): Probability of Red.

This is calculated as:

$P(Red) = \frac{Red}{Total}$

$P(Red) = \frac{38}{38+38}$

$P(Red) = \frac{38}{76}$

$P(Red) = 0.50$

Solving (b): Probability of Odd

Since each marble type is numbered 1 to 38, then half of it are odd.

i.e. 19 odd numbered red marbles and 19 odd numbered blue marbles.

So, the probability of odd is:

$P(Odd) = \frac{Odd}{Total}$

$P(Odd) = \frac{19+19}{38+38}$

$P(Odd) = \frac{38}{76}$

$P(Odd) = 0.50\\$
