1/5 is 60% of what number
1/5 = 60/100 * x
1/5 * 100/60 = x
100/300 = x
1/3 = x
Answer:
[tex] \frac{1}{3} [/tex]
Step-by-step explanation:
According to what we know, one-fifth is 60% of a number. Let us call that unknown number x. Since
[tex] \frac{1}{5} = 60\% \: \\ then \\ x = 100\%[/tex]
60% as a fraction is 6/10 or 3/5, in that case 100% as a fraction would be 5/5.
Recall: 60% = 3/5 and 100% = 5/5
therefore:
1/5 = 3/5
x = 5/5
note in order to find the value of x we cross multiply*
[tex] \frac{1}{5} ( \frac{5}{5}) = \frac{3}{5} x[/tex]
[tex] \frac{1}{5} = \frac{3}{5} x \\ \\ \frac{ \frac{1}{5} }{ \frac{3}{5} } = \frac{ \frac{3}{5} }{ \frac{3}{5} } x \\ \\ \frac{1}{5} \times \frac{5}{3} = x[/tex]
[tex] \frac{1}{3} = x[/tex]

All computers are on sale for 10% off the original price.
If x is the original price of the computer, then the function that represents the price after only a 10% discount is:
P(x) = x - 0.1x
P(x) = 0.9x
The function that gives the price, C, if only a $150 coupon is used is:
C(x) = x - 150
Choose the composition function that gives the final sale price after a 10% discount is followed by a $150 coupon.
C(P(x)) = 0.9x – 150
P(C(x)) = 0.9x – 150
C(P(x)) = 1.9x – 150
P(C(x)) = 1.9x – 150
capital gross is calculated by doing...
A)selling price-purchase price
B)purchase price-selling price
The capital gross is calculated by doing subtracting purchase price from selling price option first “selling price-purchase price” is correct.
What is capital gross?The entire value of gross fixed capital formation, changes in inventories, and acquisitions less disposals of assets for a unit or sector is used to calculate gross capital formation.
As we know, deducting the asset's or portfolio's acquisition price from the selling price yields the capital gain formula.
Thus, the capital gross is calculated by doing subtracting purchase price from selling price option first “selling price-purchase price” is correct.

After rolling a fair 20-sided die 200 times The observed or experimental probability of rolling a 20 was 25% what will happen to the probability of rolling a 20 if the dye is ruled 10,000 more times
Answer:
Step-by-step explanation:
The theoretical probability of getting a 20 in 1 throw is 1/20 = 5%.
The more times you roll the dye the closer the experimental probability moves to the theoretical.
So the probability will get less than 25% and get closer to the theoretical 5%.
If the die is rolled 10,000 more times, we can expect the experimental probability of rolling a 20 to be close to 500/10,000, which simplifies to 0.05 or 5%.
We have,
The probability of rolling a 20 on a fair 20-sided die is 1/20 or 0.05.
If the die is rolled 200 times and the observed probability of rolling a 20 is 25%,
We can calculate the number of times a 20 was actually rolled as follows:
Number of times a 20 was rolled
= Observed probability × Number of rolls
= 0.25 × 200
= 50
So, out of 200 rolls, 20 were rolled 50 times.
Now, if the die is rolled 10,000 more times, we can use the law of large numbers to expect the experimental probability of rolling a 20 to approach the true probability of 0.05.
The expected number of times a 20 will be rolled in 10,000 rolls is:
The expected number of times a 20 will be rolled
= Probability of rolling a 20 × Number of rolls
= 0.05 × 10,000
= 500
Therefore,
If the die is rolled 10,000 more times, we can expect the experimental probability of rolling a 20 to be close to 500/10,000, which simplifies to 0.05 or 5%.

art museum. What is the total number of miles Finley rode the bus on Saturday
and Sunday?
The total number of miles Finley rode the bus on Saturday and Sunday is 7.98 miles
Calculating distanceFrom the question, we are to determine the total distance travelled by Finley on Saturday and Sunday
From the given information,
On Saturday, Finley rode the bus from her apartment 3.35 miles to the city park and then 2.51 miles to the library
Total distance travelled on Saturday = 3.35 miles + 2.51 miles
Total distance travelled on Saturday = 5.86 miles
Also,
On Sunday, Finley rode the bus 2.12 miles to the art museum
Total distance travelled on Sunday = 2.12 miles
∴ Total distance travelled on Saturday and Sunday = 5.86 miles + 2.12 miles
Total distance travelled on Saturday and Sunday = 7.98 miles
Hence, the total number of miles Finley rode the bus on Saturday and Sunday is 7.98 miles.

Given ΔABC. Choose which of the following sides create a right triangle:
21
I. a=1.2,b=3.5,c=3.6
II. a=6,b=9.1,c=10.9
III. a=6,b=8,c=9
Answer:
II. a = 6 , b = 9.1 , c = 10.9
Step-by-step explanation:
I. a = 1.2 , b = 3.5 , c= 3.6
c² = a² + b²
3.6² = 1.2² + 3.5²
12.96 = 1.44 + 12.25
12.96 ≠ 13.69
These sides cannot create a right triangle.
II. a = 6 , b = 9.1 ,c = 10.9
c² = a² + b²
10.9² = 6² + 9.1²
118.81 = 36 + 82.81
118.81 = 118.81
Therefore, these sides can create a right triangle.
III. a = 6 , b = 8 , c = 9
c² = a² + b²
9² = 6² + 8²
81 = 36 + 72
81 ≠ 108
These sides cannot create a right triangle.

Find the Mean Absolute Deviation (MAD) of the following test scores.
Remember, the Mean is just the first step.
Scores:
{ 48, 61, 73, 76, 76, 74 }
Based on the calculation below, the Mean Absolute Deviation (MAD) of the test scores is 0.
How to calculate Mean Absolute Deviation (MAD)The mean of the 6 test scores is first calculated as follows:
Mean = Sum of the test scores / Number of test scores = (48 + 61 + 73 + 76 + 76 + 74) / 6 = 68
We can now calculate the MAD of the test scores as follows:
MAD = Sum of deviations of all the test scores from the Mean / Number of test scores = ((48 - 68) + (61 – 68) + (73 – 68) + (76 – 68) + (76 – 68) + (74 – 68)) / 6 = 0 / 6 = 0

Answer:
The sum of 1.8 and 1.56 is 3.36 according to the model
Sum of decimals
Given the expression 1.8 + 1.56
Using the partial sum method
1.8 + 1.56 = (1.0 + 0.8) + (1.0+0.56)
Regroup as whole and decimal number
1.8 + 1.56 = (1.0 + 1.0) + (0.8 +0.56)
1.8 + 1.56 = 2.0 + 1.36
