Peggy completed 5/6 of the math homework and Al completed 4/5 of the math homework. Did Peggy or Al complete more of the math homework?

Answers

Answer 1

Answer: Peggy completed more because more equal parts that are smaller with more shaded means it has to be more.

Answer 2

Answer:

Answer:

I would say that 4/5 is smaller than 5/6 So Al did less than Peggy Correct me if I'm wrong.

Step-by-step explanation:

For the 1st fraction, since 5 × 6 = 30,

/5= 4 × 6 = 24

5 × 6 = 30

Likewise, for the 2nd fraction, since 6 × 5 = 30,

5/6 = 5 × 5

=25

6 × 5 30

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

24 25 4 5

30 < 30

or 5 <6

Henry recorded the number of miles he biked each day for a week. His miles were 25, 40, 35, 25, 40, 60, and 75. Enter the data into the statistics calculator.what is the standard deviation of the miles Henry biked to the nearest tenth?

Answers

The standard deviation of the given data is 17.1

What is standard deviation?

Standard deviation meaning in statistics is a measure of how much the data points vary from the mean or average. It is calculated as the square root of the variance, which is the average of the squared deviations of each data point from the mean.

Given is a data set, we need to find the standard deviation of the data set,

S = 25, 40, 35, 25, 40, 60, 75

Finding the mean =

(25+40+35+25+40+60+75)/7 = 42.86

Finding the variance =

(25-42.86)² = 319

(40-42.86)² = 8.2

(35-42.86)² = 61.8

(25-42.86)² = 319

(40-42.86)² = 8.2

(60-42.86)² = 293.8

(75-42.86)² = 1033

(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9

Therefore, the standard deviation =

√291.9 = 17.1

Hence, the standard deviation of the given data is 17.1

Answer:

17.1

Step-by-step explanation:

1. Find the Mean

(25+40+35+25+40+60+75)/7 = 42.9

2.For each number, subtract the Mean and square the result.

(25-42.86)^2=319

(40-42.86)^2=8.2

(35-42.86)^2=61.8

(25-42.86)^2=319

(40-42.86)^2=8.2

(60-42.86)^2=293.8

(75-42.86)^2=1033

3. Find the Mean of those squared differences.

(319+8.2+61.8+319+8.2+293.8+1033)/7=291.9

4.Take the square root of that and this is what you want.

square root of 291.9 = 17.1

I am so confused on functions! Please help!

Answers

Functions are basically another way of expressing a way to get y or x or anything (mostly used for graphs) You will see functions like f(x)= 23y-5 (that was made up). Basically the number in the parenthesis in front of the f is what you're finding. So the equation after the equal sign is how to find whatever is being found. So in this case, finding x can be pretty easy. By the way, when graphing this you have x as the run and y as the rise.
