Answer: Our required probability is 0.304.
Step-by-step explanation:
Since we have given that
N = 21
Number of improperly drilled holes k = 4
Number of properly drilled holes = N-k= 21-4=17
Let X be the number of improperly drilled holes in a sample of 5.
We will use "Binomial distribution":
So, our required probability is 0.304.
Answer:
C) 2094.40
nearest answer.
Step-by-step explanation:
Since the given region is bounded by y = x, y = 10 and x = 0
⇒ 0 ≤ y ≤ 10
Radius and Height are 'y'
∴ The required volume
= ∫₀¹⁰2π(radius)(height)dy
= ∫₀¹⁰2π (y) (y) dy
= ∫₀¹⁰2π y² dy
= 2π ∫₀¹⁰ y² dy
Integrate y
= ![2\pi [\frac{y^3}{3}]_0^{10}](https://tex.z-dn.net/?f=2%5Cpi%20%5B%5Cfrac%7By%5E3%7D%7B3%7D%5D_0%5E%7B10%7D)
= ![2\pi [\frac{10^3}{3} - 0]](https://tex.z-dn.net/?f=2%5Cpi%20%5B%5Cfrac%7B10%5E3%7D%7B3%7D%20-%200%5D)
= 
where π is 3.142
= 2,094.66
Answer:
34 degress
Step-by-step explanation:
34+56=90
we know that the whole angle is 90 degress because its sign is given.
Answer:
2
Step-by-step explanation:
∵a+1,2a+1,4a-1 are in A.P.
2(2a+1)=a+1+4a-1
4a+2=5a
5a-4a=2
a=2
