Answer:
[tex] p =\frac{25}{40+20+25+15}= \frac{25}{100}= 0.25[/tex]
So then the probability for this case would be 0.25 or 25%
Step-by-step explanation:
For this case we have 40 black , 20 yellow, 25 orange, and 15 purple wristbands
And we want to find the probability that Melanie will select an orange wristband so we can use the definition of probability:
[tex] p =\frac{successes}{total}[/tex]
And replacing we got:
[tex] p =\frac{25}{40+20+25+15}= \frac{25}{100}= 0.25[/tex]
So then the probability for this case would be 0.25 or 25%
Mrs. Patterson’s bakery sells fruit pastries in packages of 15, while chocolate pastries come in packages of 12. What is the smallest number of each type of package you need to buy to get the same number of both type of pastries? Answer: package (s) of fruits, package (s) of chocolate
Answer: 4, 5
Step-by-step explanation:
To answer this, first find the lowest common multiple of 12 and 15.
Simplifying 12 and 15 into their factors, we get (2 * 2 * 3) and (5 * 3).
The lowest common multiple is 3.
You can then multiply each package's value by the other's factors, excluding 3. For example, we could multiply 12 by 5 and 15 by 2 * 2.
Both are equal to 60, which is the lowest number of each type of pastry you can buy in equal amounts.
60 / 15 = 4, the amount of packages of fruits needed
60 / 12 = 5, the amount of packages of chocolates needed
Yesterday, the price of a gallon of gas at five gas stations was $3.72, $3.87, $3.78, $4.09, and $3.989, respectively, but today each gas station raised its price by $0.08. What is today's mean price of a gallon of gas at the five stations?
A. 3.97
B. 4.05
C. 3.89
D. 3.81
Answer:
Option (A) 3.97.
Step-by-step explanation:
Price for one gallon of gas in gas station 1 = $3.72 (Yesterday)
Price for one gallon of gas in gas station 2 = $3.87 (Yesterday)
Price for one gallon of gas in gas station 3 = $3.78 (Yesterday)
Price for one gallon of gas in gas station 4 = $4.09 (Yesterday)
Price for one gallon of gas in gas station 5 = $3.989 (Yesterday)
Prise raised by each gas station Today = $0.08
Price for one gallon of gas in gas station 1 = $3.72 + $0.08
= $3.80 (Today)
Price for one gallon of gas in gas station 2 = $3.87 + $0.08
= $3.95 (Today)
Price for one gallon of gas in gas station 3 = $3.78 + $0.08
= $3.86 (Today)
Price for one gallon of gas in gas station 4 = $4.09 + $0.08
= $4.17 (Today)
Price for one gallon of gas in gas station 5 = $3.989 + $0.08
= $4.069 (Today)
Mean = Sum of the Terms Number of Terms / Total Number of Terms
= $3.80 + $3.95 + $3.86 + $4.17 + $4.069 / 5
= 19.849 / 5
= 3.9694
= 3.97 (Approximately)
As we can see that the Option (A) 3.97 correctly matches the answer.
So the correct answer is Option (A) 3.97.

answer:
step by step explanation:
Pls show me the work too
Answer:
1). Mean: 14.2
Median: 13.5
Step-by-step explanation:
To calculate the mean, sum all values and divide by the number of values:
(13+16+14+17+13+12) / 6 ≈ 14.2
To calculate the median, order the values from small to large and take the middle value. If there is no middle. average the two values in the middle:
12,13,13,14,16,17
The median is (13+14)/2 = 13.5.
Using this explanation you should be able to find the rest.

36 is 8 3/4% of what number?
Answer:
28.8 or 28 8/10
Step-by-step explanation:
A percentage is out of 100. We have to convert 8 3/4 into a percentage. 8 3/4 can also be written as an improper fraction 35/4. Now we have to make the denominator 100. We already knoe that 4 multiplied by 25 equals 100, then we do the same to the numerator. 35 multiplied by 25 gets us to 125. Now we got 125/100. Now since we converted the fracrion into a percentage, now what we do is divide 36 by 125% and that will get you to 28.8 or 28 8/10.
To double check your answer, you can multiply 28.8 by 125% and you will get 36.

3a + 2 - 5a = -14. Can someone solve this for me.
Answer:
a = 8
Step-by-step explanation:
-2a + 2 = -14
-2a = -16
-16/-2 = 8
a = 8
Answer:
a=8
Step-by-step explanation:
3a + 2 - 5a = -14
Combine like terms
-2a +2 = -14
Subtract 2 from each side
-2a +2-2 = -14-2
-2a = -16
Divide each side by -2
-2a/-2 = -16/-2
a = 8
Ms. Pettini's history class has too many students in it. If the class were split
into equal parts to form 3 new classes, each class would have no more than
14 students in it.
If s= the number of students in Ms. Pettini's history class, which
mathematical sentence expresses the information above?
Answer:
s/3 <= 14
Step-by-step explanation:
The number of students is divided by three because of the three clauses, hence s/3. Each new class can have 14 or less students. Therefore, s/3 <= 14.

A quadratic has been factored, as shown below:
f(x) = (x − 6)(x + 5)
What are the zeros of the quadratic?
a
6 and −5
b
6 and 5
c
-6 and 5
d
-6 and -5
Answer:
a
Step-by-step explanation:
Given
f(x) = (x - 6)(x + 5)
To find the zeros, let f(x) = 0, that is
(x - 6)(x + 5) = 0
Equate each factor to zero and solve for x
x - 6 = 0 ⇒ x = 6
x + 5 = 0 ⇒ x = - 5
