Answer: Symmetrical, Bell-shaped
Step-by-step explanation:
The Normal Probability Distribution is very popular among all because of its unique mathematical characteristics like
- Normal distributions are symmetric.
- They are unimodal (i.e. it has only one mode).
- All mean, median, mode are equal.
- It is symmetrical around center where mean, median and mode lies.
- Its curve is always a bell shaped curve.
Hence, the major characteristics of a normal probability distribution:
Symmetrical, Bell-shaped
So, let’s find out the numbers needed to form the ratio. The length of the swimming pool is 50 ft long. We need to find the perimeter. 2(50+35)
2*85
170.
So, the perimeter is 170 ft. Now we need to form the ratio. Length is first, then the perimeter.
50:170 is your ratio, but we can simplify it to 5:17. Hope this helped!
Answer:
Science Club- y=10x+20
Math Club- y=5x+50
They will be equal 6 weeks
Step-by-step explanation:
X equals the number of weeks that have passed. In example of the science club, they would gain $10 every week, making the equation y (total money) equal to 10 dollars a week (or 10x.)
Since we know they begin with 20 dollars, we'll simply add that to the 10 dollars a week.
To find the week when they will be equal, we have to put both equations equal to each other.
10x+20=5x+50
Now we solve for x, or the number of weeks when the equations (and values) will be equal.
10x+20=5x+50
5x+20=50
5x=30
x=6
So... 6 weeks :)
You can use desmos to graph if you need it.
Answer:
$3675
Step-by-step explanation:
his total income is salary+commission
commission :
15/100 * 20000
= 3000
so total income is $675 + $3000
= $3675
