Riley is playing a game that requires rolling a number cube 1-6 ans spinning a spinner with 3 consonants and 1 vowel. The sections of the spinner are all the same size. What is the probability that Riley rolls a number less than 3 and lands on a consonants. 1. 1/12 2. 3/8 3. 1/8 4. 1/8 Answer now to get 10 points!!!

Answers

Answer 1
Answer:  1/4

Work Shown:

The outcomes of the cube are {1,2,3,4,5,6}. The outcomes less than 3 are {1,2}. We have 2 outcomes we want out of 6 total, so the probability of getting an outcome less than 3 is 2/6 = 1/3.

The probability of landing on a consonant is 3/4 because there are 3 consonants and 3+1 = 4 letters total

Multiply the two probabilities: (1/3)*(3/4) = (1*3)/(3*4) = 1/4

The probability of getting a dice roll less than 3, and getting a consonant on the spinner, is 1/4.

Answer 2

Using it's concept, it is found that the probability that Riley rolls a number less than 3 and lands on a consonants is given by: [tex]\frac{1}{4}[/tex].

What is a probability?

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

For the number cube, 2 out of the 6 numbers are less than 3, hence P(A) = 2/6 = 1/3.For the spinner, 3 out of the 4 sections are consonants, hence P(B) = 3/4.

The events are independent, hence the probability of both is given by:

P(A and B) = P(A) x P(B) = 1/3 x 3/4 = 1/4.

The area of the surface of the largest known star is about 1015 square miles. The area of the surface of the Earth is about 1011 square miles. How many times larger is the star's area?

Answers

Answer:

The surface area of the star is approximately 1.004 times larger than the earth's surface area

Step-by-step explanation:

To find the number of times b which the area of the star is larger than that of the earth, we will divide the area of the area of the star by the area of the earth.

Area of surface of star = 1015 square miles

Area of surface of the earth = 1011 square miles

∴ (Area of star) ÷ (Area of the earth)

= 1015 ÷ 1011 = 1.00395 times

Therefore the surface area of the star is approximately 1.004 times larger than the earth's surface area

From the graph, we have;

For the next inequality line at y = -5, we have;

1) The inequality line, starts with an open circle on the left at x = -3, which is equivalent to less than or equal to symbol, ≤ as -3 ≤ x because the point x =-3 is the left boundary.  The inequality line extends to the point x = 2, where we have a closed circle (on the right), which is equivalent to a x ≤ 2 with the 2 on the right hand side because, the 2 is the right boundary of the inequality

2) The inequality can be summarized as starting from x = -3 extends to x = 2

3) As stated in point 1) the point x = 3, we have -3 ≤ x and at point x = 2, we have x ≤ 3 which can be combined as  -3 ≤ x < 2, to give;

{ -5 if x ∈ -3 ≤ x < 2

For the next inequality line at y = 5, we have;

1) The inequality line, starts with an open circle on the left at x = 2, which is equivalent to less than or equal to symbol, ≤ as 2 ≤ x because the point x =2 is the left boundary.  The inequality line extends to the right to reach point x = 5, where we have a closed circle (on the right), which is equivalent to a x ≤ 5 inequality, with the 5 on the right hand side because, the 5 is the right boundary of the inequality

2) The inequality can be summarized as starting from x = 2 extends to x = 5

3) As stated in point 1) the point x = 2, we have 2 ≤ x and at point x = 5, we have x ≤ 5 which can be combined as  2 ≤ x < 5, to give;

[ 5 if x ∈ 2 ≤ x < 5.

Answer:

1st box = [-4, -3]

2nd box = (-3, 2]

3rd box = (2, 5]

For f(x) = -2 we see that x is between -4 to -3 with closed endpoints.

So the interval will be [-4, -3].

For f(x) = -5 we see that x is between -3 to 2 with closed endpoint at 2 and open endpoints at -3.

So the interval will be (-3, 2].

For f(x) = 5 we see that x is between 2 to 5 with open endpoint at 2 and closed endpoint at 5.

So the interval will be (2, 5].

What is a number line?

A number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.

A horizontal number line is the most common representation and can be extended infinitely in any direction.

Given the number lines with labeled points as A, B, C, D, and E.

The midpoint of AE is the mean of AE

Mean of AE ;

(A + E )/ 2 = (- 6 + 8) / 2
