Answer: Our required probability is 0.99338.
Step-by-step explanation:
Since we have given that
n = 100
p = 0.200
So,
So, we can apply normal approximation.
Mean = 20
Standard deviation =
Since
So, Probability that fewer than 30 but a packet after testing a free sample is given by
Hence, our required probability is 0.99338.
4 feet since the shadows are half the size of the original object
B..............
c>=3 and n<0 and p<=(9-3 c)/n
Answer:
answer down below
Step-by-step explanation:
1.A+B=61
2.41+25=61
Answer:
x = 22√2
Step-by-step explanation:
In a triangle,
AB = 22
B = 90
C = 45
Now,
<em>sin </em><em>C </em><em>=</em><em> </em><em>opp/</em><em>h</em><em>y</em><em>p</em>
<em>sin </em><em>4</em><em>5</em><em> </em><em>=</em><em> </em><em>AB/</em><em>A</em><em>C</em>
<em>1</em><em>/</em><em>√</em><em>2</em><em> </em><em>=</em><em> </em><em>2</em><em>2</em><em>/</em><em>x</em>
<em><u>x = 22√2</u></em>
