We know that
• The probability of a head is 1/2.
,• The probability of a tail is 1/2.
Notice that the number of times they flip a coin is 7. Since both probabilities are the same, we just have to multiply 1/2 seven times by itself.
[tex]P=(\frac{1}{2})^7[/tex]Now, we multiply the probability with 7 since there are 7 possibilities.
[tex]P=7\cdot(\frac{1}{2})^7=7(0.0078125)=0.0546\approx0.055[/tex]Then, we multiply by 100 to express it as a percentage.
[tex]0.055\cdot100=5.5[/tex]Therefore, the answer is C. 5.5%.group 1 bought 9 tickets and received a 120 discount, group 2 bougt 3 tickets and recived a 30 dollar discount both groups spentthe total amount of money on tickets
the price of each ticket was the same
what was the cost of each ticket?
The cost of each ticket bought by each of the group is $15.
What is the cost of each ticket?The linear equation that represents the total cost spent by group 1 on the tickets is:
Amount spent = total amount spent on the tickets - discount
9x - 120
The linear equation that represents the total cost spent by group 2 on the tickets is:
3x - 30
Where:
x = is the cost of the tickets
If both groups spend the same amount, the above two linear equations would be equal to each other
3x - 30 = 9x - 120
In order to determine the value of x, take the following steps:
Combine similar terms together: 120 - 30 = 9x - 3x
Add similar terms: 90 = 6x
Divide both sides by 6
x = 90 / 6
x = 15

Miguel reads that the average low temperature today is −8.5°F and that the average high temperature is 10.2º F.
Miguel plots the points on the number line to determine the temperature change between these two readings.
What is the temperature change?
Answer:
18.7 °F
Step-by-step explanation:
You want the temperature change between a low of -8.5 °F and a high of 10.2 °F.
ChangeThe change between the two readings is found by subtracting the smaller from the larger:
10.2 -(-8.5) = 10.2 +8.5 = 18.7

Which numbers are solutions of x^2 + 20 = 9x + 2?
Answer:
x = 6 or x = 3
Step-by-step explanation:
Solve for x over the real numbers:
x^2 + 20 = 9 x + 2
Subtract 9 x + 2 from both sides:
x^2 - 9 x + 18 = 0
The left-hand side factors into a product with two terms:
(x - 6) (x - 3) = 0
Split into two equations:
x - 6 = 0 or x - 3 = 0
Add 6 to both sides:
x = 6 or x - 3 = 0
Add 3 to both sides:
Answer: x = 6 or x = 3

What is proportion?A proportion can be defined as an equation in which two elements, or numbers are being set equal to each other.
It is known as a mathematical comparison between two elements or things.
It is also defined as a comparative relation on the basis of size or magnitude of elements, quantity and numbers.
From the information given, we have that;
41 grams of sugar is in each 12-ounce can
To determine the ounces in 9 cans, we have;
If 41 grams = 12 cans
Then, x = 9 cans
cross multiply
x = 41(9)/12
expand the bracket
x = 30. 75 grams
Let's convert grams to pounds
1 gram = 0. 0022 pounds

Write the equation of a line that is parallel to the line 2x - 3y = 5 and passes through the point (3, -1)
Answer:
The equation of the line is 2x - 3y = 9
Step-by-step explanation:
Given:
Write the equation of a line that is parallel to the line 2x - 3y = 5 and passes through the point (3, -1)
Solve:
- The line is parallel to the line 2x - 3y = 5
⇒ the slope of the line = the slope of the line 2x - 3y = 5
- Rearrange the terms of the equation to be in the form
⇒ y = mx + c to find the slope of it
2x - 3y = 5 → subtract 2x from both sides
-3y = 5 - 2x ⇒ divide two sides by -3
y = 5/-3 - 2x/-3 ⇒ y = 2/3 x - 5/3
The slope of the line is 2/3
Given that: The line passes through point (3, -1)
Lets use the rule to find the equation of the line:
y - (-1)/x - 3 = 2/3
y + 1/x - 3 = 2/3 ⇒ by using cross multiplication
3(y + 1) = 2(x - 3) ⇒ open the brackets
3y + 3 = 2x -6 ⇒ put x and y on one side
2x - 3y = 3 + 6
2x - 3y = 9
The equation of the line is 2x - 3y = 9

Integers are like the above ones, but also includes the zero and negative numbers.
Rationals are the ones that can be written as a quotient between two integers, and irrationals are these ones that can't be written like that.
Finally, real numbers are all the numbers.
In this case we have the square root of a prime number, √2, this is always a irrational number.

The probability of Ryan choosing a flavor that he does not like is 3/10.
What is probability?Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of various outcomes. Statistics is the study of events that follow a probability distribution. The probability is calculated by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.So, the formula for probability:
P = favourable events/Total eventsFavorable events: (Picking flavor that Ryan does not like) = 10 + 8Total events: (sum of all the jelly) = 60Now, insert the values in the probability formula as follows:
