Play soccer: _________67% / 33% / 100%
Do not play soccer:___ 45% / 55% / 100%
Total : _____________112% / 88% / 200%
Step-by-step explanation:
play soccer: total is 90, to find percentage :
60/90 = 0.6666666667 estimated = 0.67
0.67 x 100 = 67%
30/90 = 0.3333333333 estimated = 0.33
0.33 x 100= 33%
33% + 67% = 100%
don’t play soccer : total is 60, to find percentage:
27/60 = 0.45
0.45 x 100 = 45%
33/60= 0.55
0.55 x 100 = 55%
45% + 55% = 100%
Total for first column going down
67% + 45% = 112%
Second column going down
33% + 55%= 88%
Third column going down
100% + 100% = 200%
Third column going across

Play soccer: 67% / 33% / 100%

if you rolled two dice what is the probability that you would roll a sum of 10
Answers
The probability of rolling a sum of 10 with two dice is 1/12.
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
Given that two dice are rolled and find the probability of a sum of 10.
The sample space of the event of rolling two dice is
S = {(1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6),
(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6),
(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6),
(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6),
(5, 1), (5, 2), (5, 3), (5, 4), (5, 5), (5, 6),
(6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)}
The total possible outcomes is 36.
The favorable outcomes that is the outcomes where the sum is 10 is
(1, 4), (2, 3), (3, 2).
The number of favorable outcomes are 3.
To find the probability of rolling a sum of 10 with two dice, write the sample space and then determine the number of favorable outcomes that is the outcomes where the sum is 10 and the total number of possible outcomes.
The formula to find out the probability of any event is:
\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)
By using the data and formula, the probability of rolling a sum of 10 is,
\(\text{P(event)} = \dfrac{(\text{number of favorable outcomes})}{\text{total number of possible outcomes}}\)
\(\text{P(rolling a sum of 10)} = \dfrac{3}{36}\)
On dividing both numerator and denominator by 3 gives,
\(\text{P(rolling a sum of 10)} = \dfrac{1}{12}\)
Hence, the required probability of rolling a sum of 10 with two dice is 1/12.

The probability that you would roll a sum of 10 if you rolled two dice is 1/12.
We need to consider all the possible outcomes and count the favorable outcomes to determine the probability of rolling a sum of 10 when rolling two dice.
When rolling two dice, each die has six possible outcomes, ranging from 1 to 6. To find the total number of outcomes, we multiply the number of outcomes for each die: 6 * 6 = 36.
Next, we need to count the number of favorable outcomes, which are the combinations of two dice that result in a sum of 10. These combinations include:
1. Rolling a 4 on the first die and a 6 on the second die: (4, 6)
2. Rolling a 5 on the first die and a 5 on the second die: (5, 5)
3. Rolling a 6 on the first die and a 4 on the second die: (6, 4)
There are three favorable outcomes.
Therefore, the probability of rolling a sum of 10 when rolling two dice is:
Probability = (Number of favorable outcomes) / (Number of total outcomes) = 3/36 = 1/12.
Hence, the probability is 1/12.

Perimeter = 14
Step-by-step explanation:
- Calculating the distance AB between (2,-6) and (5,-6)
AB = Square Root((x2 - x1)2 + (y2 - y1)2)
AB = Square Root((5 - 2)2 + (-6 - -6)2)
AB = Square Root((32 + 02))
AB = √(9 + 0)
AB = √9
AB = 3
- Calculating the distance BC between (5,-6) and (5,-2)
BC = Square Root((x2 - x1)2 + (y2 - y1)2)
BC = Square Root((5 - 5)2 + (-2 - -6)2)
BC = Square Root((02 + 42))
BC = √(0 + 16)
BC = √16
BC = 4
- Calculating the distance CD between (5,-2) and (2,-2)
CD = Square Root((x2 - x1)2 + (y2 - y1)2)
CD = Square Root((2 - 5)2 + (-2 - -2)2)
CD = Square Root((-32 + 02))
CD = √(9 + 0)
CD = √9
CD = 3
- Calculating the distance AD between (2,-6) and (2,-2)
AD = Square Root((x2 - x1)2 + (y2 - y1)2)
AD = Square Root((2 - 2)2 + (-2 - -6)2)
AD = Square Root((02 + 42))
AD = √(0 + 16)
AD = √16
AD = 4
- Perimeter
Perimeter of ABCD = AB + BC + CD + AD
Perimeter of ABCD = 3 + 4 + 3 + 4
Perimeter of ABCD = 14

Step-by-step explanation:
Angle 4 and 5 are the same.
Which means that angle 3 and 6 are the same.
A straight line has an angle of 180 degrees in total.
This means that we have to subtract 35 from 180.
This gives us 145.
So, the missing angle is going to be 145 degrees.
*also, 1, 4, 5, and 8 are the same angle.

Banana Cupcakes
makes 10 cupcakes
1 cup granulated sugar
cup vegetable oil
1 large egg
4 tablespoons sour cream
2 medium-sized ripe bananas, mashed
1 cups all-purpose flour
1 teaspoon baking soda
teaspoon salt
1 teaspoon vanilla extract
pinch of nutmeg
You will use the recipe above to answer the following questions:
This recipe serves 10, but you need to serve 30. What number will you need to multiply the amount of each ingredient by to adjust the recipe? How did you determine this number?
How much vegetable oil do you need for 30 cupcakes?
How much flour do you need for 30 cupcakes?
What is the difference in the amount of vanilla extract you would need for 30 cupcakes?
What is the difference in the amount of salt you would need for 30 cupcakes?
In the real world, even though you make adjustments to a recipe to accommodate the number of people you need to serve, you sometimes round the amount of an ingredient instead of using an exact amount. Which ingredient would it make more sense to round rather than coming up with the exact amount? Why?
Answers
Answer: Hey give me 1 hour and ill answer it I'm doing odessyware rn so Ill get back to you later appreciate yo patients.
Step-by-step explanation:
Then, if we want to make 30 servings, we need to use that recipe 3 times. (because x*10 = 30, then x = 30/10 = 3)
This would be equivalent to multiply each ingredient by 3.
for 30 cupcakes we need:
3 cups of vegetable oil.
3 cups of all-purpose flour
(because for each one of these ingredients we needed only 1 cup to make 10 cupcakes).
for 10 cupcakes we need 1 teaspoon of vanilla.
for 30 cupcakes we need 3 teaspoons of vanilla, the difference is 3 - 1 = 2.
So the difference is 2 teaspoons.
About which quantities we should round are those where we may have mixed numbers or big numbers.
For example, we have 4 tablespoons of sour cream for 10 servings, then for 30 servings we should have:
3*4 = 12 tablespoons.
We could round this down to 10 tablespoons.

Step-by-step explanation:
5x + 15y =20 multiply all by 3 to get 15x
15x +45y=60
- 3x +25y =75 multiply all by -5 to get 15x
15x -125y = -375
rewrite ans together
15x +45y=60
15x -125y = -375
-80y = -315
y = -315/ - 80
y = 3.9375 = y= 4 substitute to find x
5x + 15(4 )=20
5x +60 = 20
5x=-40
x= -40/5
x=-8
15x +45(4)=60
15x +180 =60
15x =-120
x=-8
a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.
