65% of 80 is what number
Answers
Answer:
52
Step-by-step explanation:
We can find the percent of a number by converting the percent to a decimal.
65%=0.65
80(0.65)=52
To find 65% of 80, first write 65% as a decimal by moving the decimal point 2 places to the left and we will get .65. Next, the word "of" means multiply, so we have (.65) (80) = 52.
Therefore, 65% of 80 is 52.

3. Given the box plot, will the mean or the median provide a better description of the center?
2ND PIC ATTACHEMENT
The mean, because the data distribution is symmetrical
The mean, because the data distribution is skewed to the left
The median, because the data distribution is skewed to the left
The median, because the data distribution is skewed to the right
4. When the outliers are removed, how does the mean change?
3RD PIC ATTACHEMENT
The mean remains the same.
The mean decreases by 2.
The mean increases by 2.
There are no outliers.

middle is 1 and 2 ... so median is 1+2/2= 1.5 and it is the median not the mean
2.I believe the only outlier is 50. Finding the mean would be 80.11.
The answer would be D
3.D. Mean always goes toward the skewness due to outliers.
Median is minimally affected by outliers.
4.We remove an outlier because we can simply assume that there was some type of extreme experimental error, or something went wrong. The mean shouldn't be effected that much, but the median will be greatly effected.

The final result is, x = 3.
The solutions we gather were x = 0,3.
We dropped x = 0 from the equation since it does not become true, so we are left with x = 3.
↓
√x = x - 1 + 1
↓
√x = x
Since 1 is the only real number whose square root equals itself, we can safely assume that x = 1.
Hope that helped! =)

Partial fractions are used in numerous aspects of everyday life, especially in fields requiring mathematical calculations. This includes engineering, calculus, computer science, signal processing, and electrical circuits. While we may not directly observe their use, their applications make many of our daily operations possible.
Explanation:
The concept of partial fractions is widely used in numerous aspects of our daily life, especially in fields that require mathematical calculations. Partial fractions make complex mathematical processes simpler and easier to solve.
For instance, in the field of engineering, partial fractions are used to simplify complex fractions in control system design, particularly in Laplace Transform. Moreover, it's also used in calculus to integrate rational functions.
In the realm of computer science, partial fractions can assist with algorithm efficiency when dealing with fractions or rational numbers. They are also used in signal processing and electrical circuits, which are a major part of our daily life as most electronics operate on these principles.
In everyday life, the use of partial fractions might not be directly observed but their applications in various fields make many of our daily life operations and technologies possible.
