7x + 4x - 11 = 22
Add 11 to both sides.
7x + 4x = 22 + 11
Simplify.
11x = 33
Divide both sides by 11.
x = 3

2/5 of the cake are left. Tiffany ate 1/5 and Omer ate 2x the amount, which is 2/5.
If x+20+35 = 180 so x = ?
Answer:
c) 125
Step-by-step explanation:
x + 20 + 35 = 180
x + 55 = 180
x = 180 - 55
x = <u>1</u><u>2</u><u>5</u>
So, the value of x is 125 (c)

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
