<u>Explanation </u><u>:</u>
<u>Given that:</u>
- In a box 25 cards are there and 1 to 25 numbers are written on them.
- • One card is drawn randomly.
<u>To Find:</u>
- • What is the probability that it is multiple of 5.
<u>We know that:</u>
P(E)= F/T
<u>Where,</u>
P(E)= Probability of an event
• F= Favourable outcomes . T = Total outcomes
<u>We have:</u>
F = Number of cards which are multiple of 5
Cards having the number 5, 10, 15, 20, 25 are the multiples of 5.
So, F = 5
T = Total number of cards
• T = 25
P(F) The probabilityP(E) = The probability that it is multiple of 5
Finding the probability that it is multiple of 5:
<u>Hence,</u>
The probability that it is multiple of 5 is ⅕

The numerator and denominator degrees of freedom
The denominator degrees of freedom is:



For the numerator, we have:


Answer:
B. 21.64
Step-by-step explanation:
We have been given a triangle and we are asked to find the length of AC (b).
We will use law of cosines to find the length of side AC.

Upon substituting our given values in the formula we will get,
Upon taking square root of both sides of our equation we will be get,
Therefore, the length of b is 21.64 and option B is the correct choice.
You can fill up 4 tanks because 20 divided by 5 is 4
A hemisphere is half a sphere.
So, the volume of a hemisphere is the half of the volume of the complete sphere.
The formula for the volume of a sphere is:
V = (4/3) π (radius)^3
Using π = 3.14 and radius = diameter / 2 = 50 feet / 2 = 25 feet.
You get:
V = (4/3) (3.14) (25 feet)^3 = 65,416.7 feet^3
Answer: 65,416.7 cu. ft.
