Please help. Which spinner will give maria the best probability of winning a prize
Explain why.
Answers
Spinner A has the same scenario, except that green has a 50% chance to be chosen while orange and yellow have a 1/4 chance of being chosen each.
Spinner C, however, represents that orange and yellow individually have a 1/6 chance of being chosen and green has a 4/6 chance of being chosen. This would mean that in this spinner, there is an approximate 66% chance that green would be chosen, which leaves orange and yellow with a total of an approximate 33% chance.
Because spinner B has one of the colors with the greatest fraction that are in favor of Maria winning the prize, she should go with spinning spinner B. If you need any extra help, let me know and I will gladly assist you.

In a football tournament, each team played exactly 19 games. Teams get three points for everyone and one point for every time. At the end of the tournament, team Olympus got a total of 28 points. How many could team Olympus have tied?
Answers
We can actually deduce here that when the tournament ended, team Olympus have tied for 13, 10, 7, 4, 1 times.
What is inequality?In Mathematics, inequality is used to express or show quantities that are less than, greater than, greater than or equal to, less than or equal to.
The following can be seen in inequality expressions:
≤≥ ><≠Looking at the question, we can see that each team plays exactly 19 games.
Every win (w) = 3
Every tie (t)= 1
Every loose = 0
But Olympus got a total of 28 points
Thus: 3w + t = 28 ---------(1)
Note that each team plays 19 games
Thus, T + W ≤ 19 --------------(2)
and T , W ≥ 0
Looking at equation (1) and (2)
=> 2W ≥ 9
=> W ≥ 4.5
( match can be won in integers only )
=> W ≥ 5
W - 5, 6, 7, 8, 9
T - 13, 10, 7, 4, 1
Loose - 1, 3, 5, 7, 9
Thus, team Olympus have tied for 13, 10, 7, 4, 1 times.

Congruent angles intercept congruent chords, so since the circumference of a circle exists 360 degrees, arc angle 1 exists inscribed in measures 110 degrees.
So, by the inscribed angle theorem, angle 1 measures 55 degrees.
What are congruent angles?Congruent angles exist as two or more angles that exist identical to each other. Therefore, the measure of these angles exists equivalent to each other. The kind of angles does not create any distinction in the congruence of angles, which implies they can be acute, obtuse, exterior, or interior angles.
The Inscribed Angle Theorem states that the measure of an inscribed angle exists half the measure of its intercepted arc. Inscribed angles that intercept the exact arc exist congruent. This exists named the Congruent Inscribed Angles Theorem and exists shown below.
∠ A D B and ∠ A C B intercept, so m ∠ A D B = m ∠ A C B.

The number of permutations of picking 4 pens from the box is 30.
There are six different unique colored pens in a box.
We have to select four pens from the different unique colored pens.
We have to find in how many different orders the four pens can be selected.
What is a permutation?A permutation is the number of different arrangements of a set of items in a particular definite order.
The formula used for permutation of n items for r selection is:
[tex]^nP_r = \frac{n!}{r!}[/tex]
Where n! = n(n-1)(n-2)(n-3)..........1 and r! = r(r-1)(r-2)(r-3)........1
We have,
Number of colored pens = 6
n = 6.
Number of pens to be selected = 4
r = 4
Applying the permutation formula.
We get,
= [tex]^6P_4[/tex]
= 6! / 4!
=(6x5x4x3x2x1 ) / ( 4x3x2x1)
= 6x5

The sum of three numbers is 100. The second number is 2 times the third. The third number is 8 less than the first. What are the numbers?
Answers
Answer:
Step-by-step explanation:x+y+z=100(let x ,y,z represent the first second and third numbers respectively)
Therefore,y=2z
z=x-8
y=2x-16
substituting the values of x,y and z into the question,we have
x+(2x-16)+(x-8)=100
Simplifying,we have
4x-24=100
adding 24 to both sides of the equation,
4x=100+24
4x=124
dividing both sides of the equation by the co-efficient of x,we have
4x/4=124/4
4.31=124
therefore,x=31.
