The last two questions on a quiz were a
true or false question and a multiple choice
question with 4 answer choices. Each ques-
tion had only one right answer. What is the
probability of guessing ______
(a) both questions correctly

(b) both questions incorrectly

(c) both correctly from the remaining
options, knowing that a and b on the
multiple choice were incorrect


Write the probability as a reduced fraction, decimal rounded to the hundreds place, and a whole percent

Answers

Answer 1

Answer:

(a) The probability of guessing both questions correctly is (1/2) * (1/4) = 1/8, or 0.125, or 12.5%.

(b) The probability of guessing both questions incorrectly is (1/2) * (3/4) = 3/8, or 0.375, or 37.5%.

(c) The probability of guessing both questions correctly from the remaining options is (1/3) * (1/3) = 1/9, or approximately 0.111, or 11.1%.

Answer: 33.3%

Step-by-step explanation:

Since you want numbers less than 3, that would mean you want the sides with #1 and #2. And since there are six sides on the dice, you would put the number of sides you wish over the total number of sides. This would be 2/6 which could be simplified to 1/3 and if you want a decimal answer divide 1/3 to get a repeating decimal then move two decimal places to the right to make it 33.3% (This is rounded to the nearest tenth decimal place)

probability of rolling ________
(a) a 1 and then a 6
(b) an even number and then an odd
number
(c) a number less than 3 and then a
number greater than 3


Write the probability as a reduced fraction

Answers

Answer:

Part - A = 1/36

Part - B = 1/4

Part - C = 1/6

Step-by-step explanation (Part - A):

The numbers on the cube are, 1 , 2 , 3 , 4 , 5 and 6.

Formula to calculate probability =
Total Number of the particular number / Total Number of Numbers

The probability of rolling 1 is 1/6 as there is only one 1 in a numbered cube.

The probability of rolling 6 is 1/6 as there is only one 6 in a numbered cube.

So, the probability of rolling 1 and 6 is 1/6 * 1/6.

The probability of rolling 1 and 6 = 1/36.


Step-by-step explanation (Part - B):

The numbers on the cube are, 1 , 2 , 3 , 4 , 5 and 6.

Formula to calculate probability =
Total Number of the particular number / Total Number of Numbers

The probability of rolling an even number is 3/6 = 1/2 because there are 3 even numbers in a numbered cube.

The probability of rolling an odd number is 3/6 = 1/2 because there are 3 odd numbers in a numbered cube.

So, the probability of rolling an even and an odd number is 3/6 * 3/6 = 1/2 * 1/2.

The probability of rolling an even and an odd number = 9/36 = 1/4.


Step-by-step explanation (Part - C):

The numbers on the cube are, 1 , 2 , 3 , 4 , 5 and 6.

Formula to calculate probability =
Total Number of the particular number / Total Number of Numbers

The probability of rolling a number that is less than 3 is 2/6 = 1/3 because there are 2 numbers that are less than 3 in a numbered cube.

The probability of rolling a number that is greater than 3 is 3/6 = 1/2 because there are 3 numbers that are greater than 3 in a numbered cube.

So, the probability of rolling a number that is less than 3 and a number that is greater than 3 is 2/6 * 3/6 = 1/3 * 1/2.

The probability of rolling a number that is less than 3 and a number that is greater than 3 is 6/36 = 1/6.

Answers

Answer: A

Explanation: The y intercept it set on -10 and the x intercept is on 4. To find the slip you will count how far the y intercept is from the origin which is 10 spots away, then how far the x intercept is away from the origin which is 4 spots away. Since both are factors of 2 you divide each part my 2 to give you the slope of 5/2

Answer:

A.  Slope = 5/2 , y-intercept = -10

Step-by-step explanation:

To find the y-intercept, it is always at the point on the y-axis where x=0. In the graph, the function crosses over -10 at x=0. So the y=intercept would be -10.

The slope "equation" is rise/run, aka y / x. In this case, an easy way to find it is by taking the y-intercept and seeing how far it is away from the origin. It is 10 away from the origin. Since this graph is heading right and upwards, it is increasing, resulting in the slope being positive. To find the "x" portion, from the origin, find when the graph crosses the x-intercept (the point where the line crosses through the x-axis). In this case, it will be 4.

Now that we know our y value and x value, put them into the slope formula.

Slope = rise/run --> 10/4 ---> 5/2

which of the following equations has exactly one solution?

A. 3x+5-x-2x=1
B. 8-2(x+1)=6x+6
C. 5x+3+x=3(2x+1)
D. 4(x-4)= 2x+2(x-4)

Answers

A. 3x+5-x-2x=1 has only one solution.

To have exactly one solution, the equation must be consistent (have a solution) and not have infinitely many solutions. An equation will have infinitely many solutions if both sides of the equation simplify to the same expression, meaning that any value of x that satisfies one side of the equation will also satisfy the other side. Therefore, we need to simplify each equation and check for consistency and the possibility of infinitely many solutions.

A. 3x + 5 - x - 2x = 1

Simplifying, we get:

0 = -6x - 4

6x = -4

x = -2/3

This equation is consistent and has exactly one solution, x = -2/3.

B. 8 - 2(x + 1) = 6x + 6

Simplifying, we get:

6 - 2x = 6x + 6

-8x = 0

x = 0

This equation is consistent, but it simplifies to -8x = 0, which means that any value of x will satisfy the equation. Therefore, this equation has infinitely many solutions.

C. 5x + 3 + x = 3(2x + 1)

Simplifying, we get:

6x + 3 = 6x + 3

0 = 0

This equation simplifies to 0 = 0, which means that any value of x will satisfy the equation. Therefore, this equation has infinitely many solutions.

D. 4(x - 4) = 2x + 2(x - 4)

Simplifying, we get:

4x - 16 = 4x - 8

-16 = -8

This equation simplifies to -16 = -8, which is not true for any value of x. Therefore, this equation is inconsistent and has no solutions.

Therefore, the only equation that has exactly one solution is A. 3x + 5 - x - 2x = 1.

Y=-x+18

-4+18=14

So, y[tex]\neq[/tex]-x+18

C- Let's take point 4,10

Y=-2x+18

-8+18=10

y does =-2x+18

D-  wrong since C is right

Answer:

The correct answer is C.

Step-by-step explanation:

First off, identify the y-intercept. In this case, the y-intercept, or b, is 18. Now that we got the y-intercept, we have to identify if the slope is going up or down. In this particular case, the slope is going down, so the slope is negative. Slope is always delta y over delta x, rise over run in how they teach this in schools, so we have to find two points in particular. I chose (0, 18) and (2, 14) since they're the easiest to find out. We do 18 minus 14, which gives us 4. We then do 0 minus 2, giving us negative 2. 4 over negative 2 is negative 2, which is our slope. We try to match this with one of our answers, and C gives us an exact replica. C is the correct answer.
