Ms.Nichols recorded the amount of time, in minutes, that she exercised during the first ten days of the month. 30,45,25,25,35,5,40,35,40,20. What is the mean of the data set?
Answers
Hi!
I'm Happy to help you today!
The answer to this question would be 30!
This is because to find the mean you have to add everything up, then divide it by how many number's there are so for this problem it is:
30 + 45 + 25 + 25 + 35 + 5 + 40 + 35 + 40 + 20 = 300
Then Divide!
300 ÷ 10 = 30
So 30 is your answer!

A bakery sold 36 brownies in a day, which was 30% of the total items sold that day. What was the total number of items the bakery sold that day?
(show work please)
Answers
Answer: The answer is 120
Step-by-step explanation:
We know that 36 is 30% of total items
So our equation would be 36/? = 30/100
From there we cross multiply so 36x100 = 3600
From there, we divide 3600 by 100
Therefore, your answer is 120

You pay 15 dollars for something that was 25% off. What was the original price of the hat before the discount?
Answers
Answer:$18.75
Step-by-step explanation: 15*0.25=3.75
15+3.75=18.75
Answer:
20
Step-by-step explanation:
So we first subtract 25% from 100% so we can see what percent 15 is:
100 - 25 = 75 so 15 is 75% of ___:
This gives us a standard percentage problem, so:
75% = 0.75
we can rewrite the equation as a one-step equation:
15 = 0.75a
Dividing both sides by 0.75 and swapping sides gives
a = 15 ÷ 0.75 = 20
So the original price of the hat was $20
OR
because 25% is 1/4, and 75% is 3/4 and 15 is therefore 3/4:
15 ÷ 3 = 5
5 x 4 = 20

A fair 6-sided die is rolled 360 times. What is a reasonable prediction for the number of times the event of landing on an odd number will occur?
60
180
240
320
Answers
Answer:
correct answer is B) 180.
Step-by-step explanation:
When rolling a fair 6-sided die, there are three odd numbers (1, 3, and 5) and three even numbers (2, 4, and 6). The probability of rolling an odd number on a single roll is therefore 3/6 or 1/2.
If the die is rolled 360 times, we can expect that the event of landing on an odd number will occur roughly (1/2) * 360 = 180 times, on average. Therefore, the most reasonable prediction for the number of times the event of landing on an odd number will occur is 180.

Answer:
The answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent
Step-by-step explanation:
By adding all the numbers you get 500, but you need to make it 100% so you divide the total number by five. To know what percent out of 100 you need to divide all of the variables by 5.
85 ÷ 5 = 172
40 ÷ 5 = 48
125 ÷ 5 = 25
50 ÷ 5 = 10
Thus the answer to your problem is, B. a circle graph titled social media usage, with four sections labeled vidtok 17 percent, headbook 48 percent, picturegram 25 percent, and tweeter 10 percent

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Light travels from the sun at 1.12 x 107 miles per minute. The planet, Mars, is approximately 1.42 x 108 miles away from the sun.
What is the approximate amount of time, in minutes, for light to travel from the Sun to Mars? Write your answer in scientific notation rounded to the nearest hundredth.
Answers
Answer:
Time = 1.27 x 10^1 minutes
Step-by-step explanation:
To calculate the approximate amount of time it takes for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light.
Given:
Speed of light = 1.12 x 10^7 miles per minute
Distance between the Sun and Mars = 1.42 x 10^8 miles
Time = Distance / Speed
Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)
Time = (1.42 / 1.12) x 10^(8 - 7) minutes
Time = 1.27 x 10^1 minutes
Rounded to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.70 minutes in scientific notation.
Time = Distance / Speed
Given:
Speed of light = 1.12 x 10^7 miles per minute
Distance from the Sun to Mars = 1.42 x 10^8 miles
Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)
To simplify the calculation, we can divide the numerical values and subtract the exponents:
Time = 1.42 / 1.12 x 10^(8 - 7) minutes
Time = 1.27 x 10^1 minutes
Rounding to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.7 minutes in scientific notation.

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.
The volume of a cone is 80π cubic units. The radius of this cone is tripled.
Eric says the new volume will be tripled. It is 240π cubic units.
Natalie says the new volume will be multiplied by 9. It is 720π cubic units.
Who is correct? Explain your reasoning.
Answers
V = (1/3)πr^2h
Where V is the volume, r is the radius, and h is the height. If the radius of a cone is tripled, the volume of the cone will be multiplied by 9. This is because the radius is squared in the formula, so tripling the radius is the same as multiplying it by 3*3=9.
To see this more clearly, consider the following example:
Suppose the radius of a cone is 2 units and the height is 4 units. The volume of the cone is:
V = (1/3)π(2^2)(4) = (1/3)π(4)(4) = (1/3)π(16) = 16π/3 cubic units
If we triple the radius of the cone to 6 units, the volume of the cone becomes:
V = (1/3)π(6^2)(4) = (1/3)π(36)(4) = (1/3)π(144) = 144π/3 cubic units
The volume of the cone has been multiplied by 9.

How many integers between 2020 and 2400 have four distinct digits arranged in increasing order?
Answers
Answer: E=15
There are 15 integers between 2020 and 2400 which have four distinct digits arranged in increasing order.
Step-by-step explanation:
This can be obtained by after a simple counting of number from 2020 and 2400 as follows:
The first set of integers are:
2345, 2346, 2347, 2348, and 2349.
Therefore, there are 6 integers in first set.
The second set of integers are:
2356, 2357, 2358, and 2359.
Therefore, there are 4 integers in second set.
The third set of integers are:
