Answer:
Option D.
Step-by-step explanation:
In this question figure of pyramid is attached below the question .
Surface area of the rectangular pyramid :
Area of the Base = Length × Width
= 10 × 2 = 20 cm²
Area of Lateral #1 =
=
= 31.5 cm²
Area of Lateral #2 =
=
= 8 cm²
Surface area of the pyramid = 20 + 2(31.5) + 2(8)
= 20 + 63 + 16
= 99 cm²
Surface area of the pyramid is 99 cm²
Answer: 60%
1000÷2=500
Clive: 500-100= 400
Gillian: 500+100= 600 (Because Gillian has 100 more votes than Clive)
Answer:
a.
b.
Step-by-step explanation:
We are given that
a.Substitute z=0
...(1)
..(2)
Subtract equation (1) from equation (2)
Substitute y=0 in equation(1)
The point (6,0,0) lie on a line.
Let
Therefore, the vector
Line is parallel to vector a' and passing through the point (6,0,0).
The parametric equation is given by
Using the formula
The parametric equation is given by
Angle between two plane
and
Using the formula
Where in degree.
Answer:
The probability of getting exactly 2 soles is 0.375.
Step-by-step explanation:
The question is:
If you toss a fair coin 4 times, what's the probability that you get exactly 2 soles?
Solution:
A fair coin has two parts.
On tossing a coin once there is 50-50 odds of both the sides.
So, the probability of one side is, <em>p</em> = 0.50.
It is provided that a fair coin is tossed <em>n</em> = 4 times.
The event of any of the sides showing up after the toss are independent of each other.
The random variable <em>X</em> defined as soles, follows a Binomial distribution with parameters <em>n</em> = 4 and <em>p</em> = 0.50.
The probability mass function of <em>X</em> is:
Compute the probability of getting exactly 2 soles as follows:
Thus, the probability of getting exactly 2 soles is 0.375.
