Answer: 2(x + 5) less than 3x
Step-by-step explanation: 2 = twice the... x + 5 = the sum of a number and 5 (number = x) 3x = three times the number
Solution:
Number of times a die is rolled = 20
1 - 3=A
2 - 5=B
3 - 4=C
4 - 2=D
5 - 3=E
6 - 3=F
Total number of arrangements of outcomes , when a dice is rolled 20 times given that 1 appear 3 times, 2 appears 5 times, 3 appear 4 times, 4 appear 2 times , 5 appear three times, and 6 appear 3 times
= Arrangement of 6 numbers (A,B,C,D,E,F) in 6! ways and then arranging outcomes
= 6! × [ 3! × 5! × 4!×2!×3!×3!]
= 720 × 6×120×24×72→→[Keep in Mind →n!= n (n-1)(n-2)(n-3)........1]
= 895795200 Ways
The length of the radius of the cylinder is 2 units.
The lateral surface area of a cylinder = <span>
2πrh</span>
where, r = base radius
h = height of cylinder
Now, height of cylinder = 2r units
⇒ 16 π = 2×π×r×<span>h
</span>⇒ 16 π = 2×π×r×2r
⇒
= 4
⇒ r = 2 units
Thus, radius is 2 units.
The four is in the thousandths place.
Answer:
REAL NUMBER - real number is union of rational and irrational numbers .... whole numbers, natural numbers, integers, rational and irrational numbers are included in real numbers.
INTEGER -. integer means
means whole - valued positive or negative number or 0......
suppose 1, 2, 3, -6, -2....
whole numbers, such as 3, 4, but not 3.6 or √4 .
I hope you understand the difference between real numbers and integers.......
