the spinner below is spun three times, find all possible outcomes. the spinner has 12 numbers
For the spinner with 3 sectors, the total number of outcomes for 3 spins is 27.
What is the combination?
A combination is a mathematical technique that determines the number of possible arrangements.
Let's we have to define
A, B, and C, as the regions in the spinner.
So, we spin it 3 times, and for each of these times there are 3 outcomes, so the outcomes will be of the form:
The outcome of spin 1, the outcome of spin 2, outcome of spin 3.
The total number of different outcomes will be:
3^3 = 27

- The spinner shown is spun 4 times. What is the probability that you will spin gray at least 2 times?
Answer:
26.17%
Step-by-step explanation:
P(Grey) = 1/4
P(Grey at least 2 times in 4) = 1 - P(no Grey in 4) - P(1 Grey in 4)
P(no Grey in 4) = 4C0 * 3/4 * 3/4 * 3/4 * 3/4 = 81/256
P(1 Grey in 4) = 4C1 * 1/4 * 3/4 * 3/4 * 3/4 = 27/64
P(Grey at least 2 times in 4) = 1 - 81/256 - 27/64 = (256-81-108)/256=67/256=26.17%

Answer:
(6, 0)
Step-by-step explanation:
Coordinates are written in the form (x, y), where x is the x-axis value that the point is in, in this case 6, and where y is the y-axis value, in this case 0.
Hi!
Answer:
(6, 0)
Step-by-step explanation:
Coordinate point "G" on this graph is on the very bottom. On the X axis, point G is on the 6. On the Y axis, its on the 0, so since the domain, (X) comes first before the range, (Y), you get (6, 0)

Don't worry about the x and w, I just need the answer to y. Find the value of y if JKLM~PQRS
Answer:
y = 15
Step-by-step explanation:
JKLM ~ PQRS means that quadrilateral JKLM is similar to quadrilateral PQRS.
In similar shapes the corresponding sides have same ratio and the corresponding angles are congruent.
This means angle J is congruent to angle P, K is congruent to Q, L is congruent to R and M is congruent to S. Order of the vertices matters.
Solving for y.
Angle J is congruent to angle P.
5y - 4 = 71 Add 4 on both sides.
5y = 71 + 4
5y = 75 Divide both sides with 5.
y = 15

Help can you help me with angles please ＞﹏＜
===========================================================
Explanation:
There are two approaches here.
Method 1
Focus on the numbers along the top only.
The left arrow points at 50 while the arrow on the right points at 180. Subtract these numbers to get 180 - 50 = 130
------------------------------
Method 2
Focus on the numbers along the bottom row this time.
The left arrow points at 130 and the right arrow points at 0
The difference of which is 130 - 0 = 130
Because we're subtracting off 0, it means we can simply look at only one number without having to do any math. This only works if the other portion of the angle is pointing at 0 or 180.
------------------------------
Notice that 130 degrees is larger than 90, so this angle is obtuse. This means that if you aren't sure whether to go with 50 or 130, it will depend on if it's acute or obtuse.

Find the value of x.
135°
(7x + 2)°
x = [?]°
The required value of the x in the expression of angle is 19.
An expression of angle is given as 7x + 2 = 135°, the value of the x is to be determined.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
7x + 2 = 135
Simplifying,
7x = 135 - 2
7x = 133
x = 133 / 7
x = 19
Thus, the required value of the x in the expression of angle is 19.

Answer:
a) 11/100
b) 60 times
Step-by-step explanation:
a)
We want to find the probability that a 3 will be rolled.
Probability = # of favorable outcomes / total # of outcomes.
Here the number of favorable outcomes will be the number of times a 3 was rolled and the total number of outcomes will simply be the # of times that the dice was rolled which can be calculated by finding the sum of the frequencies of each number.
So # of favorable outcomes = 11 ( as the dice was rolled on a 3 11 times.)
And the total number of outcomes would be 100 ( the sum of the frequencies , 12 + 35 + 11 + 23 + 7 + 12 = 100 )
So the probability of rolling a 3 would be 11/100
b)
For this part we want to find the expected times that a 6 would be rolled if we rolled the die 500 more times.
To calculate this we simply find the probability of rolling a 6 and then multiply that by 500.
So again probability = # of favorable outcomes / total # of outcomes.
Here # of favorable outcomes is frequency of rolling a 6 which would be 12 and the total number of outcomes is 100 as we found out during the last part.
So the probability of rolling a 6 is 12/100 or 3/25
We then multiply this by 500 to find the expected number of times a 6 would be rolled if the dice was rolled 500 more times
So our answer = 3/25 × 500 = 60 times
