Y = mx + b is the slope-intercept form of the equation of a line,
where m = slope, and b = y-intercept.
In problems 1 and 3, your equations are written in the y= mx + b form, so you can read the slope and y-intercept directly.
1.
m = -5/2
b = -5
3.
m = -1
b = 3
5.
For problem 5, you need to solve for y to put the equation
in y = mx + b form. Then you can read m and b just like we did
for problems 1 and 3.
4x + 16y = 8
16y = -4x + 8
y = -4/16 x - 8/16
y = -1/4 x - 1/2
m = -1/4
b = -1/2
The average speed is the distance divided by the time.
Total distance:
12.8 miles + 17.2 miles = 30 miles
Total time:
noon - 9:00 a.m. = 3 hours
6:00 p.m. - 1:00 p.m. = 5 hours
Total time = 3 hours + 5 hours = 8 hours
average speed = 30 miles / 8 hours = 3.75 miles per hour
It’s 35 degrees since you do 180-125 to get 35. :)
Observation that we can make is min = 10, max = 19, range = 9, Maximum frequency of a number is 12, Average = 12.9, median = 12, mode = 12 it is slightly skewed on the right.
Step-by-step explanation:
- It is imperative to create a data in a tabular column before analyzing.
- Once the data is created use tally marks or frequency distribution.
- Frequency distribution helps the data to provide occurrence of event.
- Very important to number which is a counting numbers are discrete.
- Continuous of data are ones which are in decimal.
- Descriptive statistics is the 1st level of Statistics.
- It finds, where the data stands. Minimum, Maximum is understandable.
- Range is at what level data is expanded.
- Average is the one numeric of a number.
- Median is the mid point of data
- Mode is the repetitive number of the data.
- Skewness is whether data is having extreme directions.
Answer:
d. 15-(-18)
Step-by-step explanation:
Take the second point and subtract the first point
15 - (-18)
15 + 18
33
