Answer:
60%
Step-by-step explanation:
To solve this, we need to divided 18 by 30, and the multiply the result by 100%:
percentage 18 out of 30 = [tex](\frac{18}{30} )[/tex](100%)
percentage 18 out of 30 = (0.6)(100%)
percentage 18 out of 30 = 60%
We can conclude that 18 is the 60% of 30.
Check your work:
Find the 60% of 30
First, we convert the percentage to decimal by diving it by 100%
60% = (60%/100%) = 0.6
Next, we multiply the decimal by 30
(0.6)(30) = 18
We just confirmed that 18 is the 60% of 30.

What is the median of this set of data values 11,13,14,15,18,20,23,26
Answer: The required median of the given data set is 16.5.
Step-by-step explanation: We are given to find the median of the following set of values :
11, 13, 14, 15, 18, 20, 23, 26.
We know that
(i) If the data contain an odd number of values, then the mid-value is the required median.
(ii) If the data contain an even number number of values, then the average of the two mid-values will be the required median.
Since the given data contains 8 values, which is an even number, so we will consider two mid-values and those are 15 and 18.
The average of 15 and 18 is given by

The difference is 6
Step-by-step explanation:
The difference means the absolute value, so not what -4-2 is, but how far apart these two are on a number line. We need to take the absolute value of -4-2 so |-4|-|2|=|-6| and absolute value ignores signs so your answer is 6. Let me know if you need more help
if you place these marbles in a bag, close your eyes, and choose a marble, what is the probability that it will be
Answer:
P(blue) = 3/7
So '7' belongs in the box
Step-by-step explanation:
There are 14 total marbles, 6 of which are blue. The probability of pulling a blue marble out of the bag is
P(blue) = 6/14, which reduces to 3/7
The probability of drawing a particular marble from a bag depends on the number of that marble initially in the bag and whether the marbles are replaced after being drawn. Probabilities are calculated based on these conditions, including removing a marble of a particular color after another specific color has been removed.
Explanation:The subject of the question is probability, a concept in mathematics. The possibility of drawing a particular color of marble from a bag depends on how many of that color is in the bag to start with, as well as whether or not the marbles are replaced after being drawn.
In the case of James and his bag of four blue and three white marbles, the probability of drawing a blue marble is 4 out of 7 the first and second time he draws because the blue marble is replaced each time.
On the other hand, if the first drawn marble is not replaced (like in the second example), the total number of marbles, and thus the probabilities, change. For instance, after drawing and setting aside one blue marble from a bag containing four blue and three white marbles, the probability of drawing another blue marble becomes 3 out of 6, or 1/2.
Finally, in the case of Mark and his bag of green, red, and yellow marbles, the probability of drawing a yellow marble and then a green marble without replacement can be calculated as the product of the possibility of attracting a yellow marble first, and then the conditional probability of drawing a green marble given that a yellow one has already been removed. This shows how probabilistic events can be dependent on one another.

Final answer:
1/12 of the Brown family's garden is planted with carrots, as the vegetable section is 1/3 of the garden and is equally divided among four types of vegetables.
Explanation:
The Brown family is planting 1/3 of their garden with flowers, 1/3 with berries, and 1/3 with vegetables.
The vegetable section is equally divided into four parts for carrots, onions, peppers, and tomatoes.
To find the fraction of the garden planted with carrots, you would divide the vegetable section's fraction by the number of vegetable types.
Since 1/3 of the garden is planted with vegetables, and there are 4 types of vegetables, the fraction of the garden with carrots is:
1/3 ÷ 4 = 1/3 × 1/4 = 1/12.
Therefore, 1/12 of the garden is planted with carrots.
There are bytes in a gigabyte. There are bytes in a megabyte. How many times greater is the storage capacity of a 1-gigabyte flash drive than a 1-megabyte flash drive?
Answer:
1000 times greater
Step-by-step explanation:
1 gigabyte = 1000000000 bytes
1 mega byte = 1000000 bytes
Therefore;
1 gigabyte = 1000 megabyte
Thus;
The storage capacity of 1 gigabyte is 1000 times greater than a flash drive with a capacity of 1 megabyte
Answer:
"1,000 times greater"
Step-by-step explanation:
We will do the calculation in BYTES.
We want to figure out HOW MANY TIMES GREATER is 1 Gigabyte than 1 Megabyte.
1 Gigabyte (GB) = 10^9 Bytes
1 Megabyte (MB) = 10^6 Bytes
So, how many times is 10^9 is of 10^6? We just need to divide 10^9 by 10^6.
[tex]\frac{10^9}{10^6}=\frac{1000000000}{1000000}=1000[/tex]
So, 1 GB is 1000 times greater than 1 MB.

What is the equation of the line, in point-slope form, that passes through the points (9, 1) and (4, 16)?
A. y + 1 = -3(x + 9)
B. y - 1 = -3(x - 9)
C. y + 1 = 3(x + 26)
D. y - 1 = 3(x - 26)
Answer:
B. y - 1 = -3(x - 9)Step-by-step explanation:
The point-slope form of an equation of a line:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
(x₁, y₁) - point
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (9, 1) and (4, 16). Substitute:
[tex]m=\dfrac{16-1}{4-9}=\dfrac{15}{-5}=-3[/tex]
[tex]y-1=-3(x-9)[/tex]
The equation of the line that passes through the points (9, 1) and (4, 16) in point-slope form is y - 1 = -3(x - 9).
Explanation:To find the equation of a line, we can use the point-slope form, which is y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope of the line.
Given the points (9, 1) and (4, 16), we can calculate the slope using the formula m = (y₂ - y₁) / (x₂ - x₁).
Substituting the values, we get m = (16 - 1) / (4 - 9) = -3. So, the equation of the line in point-slope form is y - 1 = -3(x - 9).

Answer:
the mean is 4.2
Step-by-step explanation:
Answer:
Mean absolute deviation: 1.84.
Step-by-step explanation:
How do you find the mean absolute deviation for a bunch of numbers?
Calculate the average (a.k.a. mean) of the numbers.Calculate the absolute difference (just discard any negative "-" sign in front of the difference) between each number and the mean. The mean absolute deviation is the average of all those absolute differences.What's the mean of those numbers?
(3 + 5 + 8 + 1 + 4) / 5 = 4.2.
Absolute difference:
3 - 4.2 = -1.2. Drop the negative sign to get 1.2.5 - 4.2 = 0.8.8 - 4.2 = 3.8.1 - 4.2 = -3.2. Drop the negative sign to get 3.2.4 - 4.2 = - 0.2. Drop the negative sign to get 0.2.What's the average of those absolute differences?
(1.2 + 0.8 + 3.8 + 3.2 + 0.2) / 5 = 1.84. That's the mean absolute deviation of those five numbers.

How do you simplify 16m^2/24m^7
To simplify 16m^2/24m^7, you divide both numbers by 8 and subtract the exponents, getting 2/3m^(-5), which is then rewritten with positive exponents as 2/(3m^5).
Explanation:To simplify the expression 16m^2/24m^7, we need to reduce the fraction by dividing both the numerator and the denominator by their greatest common factor. Additionally, we apply the laws of exponents to simplify the expression further.
First, we observe that 16 and 24 have a common factor of 8. So we divide both by 8:
16 / 8 = 2
24 / 8 = 3
Now our expression looks like this:
2m^2 / 3m^7
Next, we apply the laws of exponents. Since both the numerator and denominator have the base m, we subtract the exponent in the numerator from the exponent in the denominator:
m^2 / m^7 = m^(2-7) = m^(-5)
Combining the reduced coefficients and the exponents, we get:
2/3m^(-5)
To have positive exponents, we can write:
2/(3m^5)
