x = average of next 5 quizzes
4 * 73 = first 4 quizzes
There will be a total of 4 +5 = 9 quizzes
Average of all quizzes = 88 = (4*73+5x)/9
9*88 = 9*(292 +5x)/9
792 = 292 + 5x
500 = 5x
X = 500/5 = 100
<span> Next 5 quizzes need
to average 100</span>
Answer:
0.651%
Step-by-step explanation:
using Binomial expansion: nCr*p^n*(1-p)^(n-r)
probability he will get at least 5 hits in the game = probability he will get 5 hits in the game + probability he will get 6 hits in the game + probability he will get 7 hits in the game = 7C5*0.215^5*(1-0.215)^2 + 7C6*0.215^6*(1-0.215)^1 +7C7*0.215^7*(1-0.215)^0 = 21* 0.0004594*0.616225 + 7*0.00009877*0.785 + 1*0.000021235 = 0.00651 = 0.651%
P^4, p^3,p^2,p is descending powers of p. Hope this helps!
Answer:
Q=(2,-1)
Step-by-step explanation:
We are given point as N=(-1,2)
Point Q is symmetric to point N with respect to line y=x
we know that any point symmetric with respect to line y=x means inverse of that point
For example: If we have to find symmetric about y=x line of point (a,b)
a changes to b
and b changes to a
so, symmetric of (a,b) with respect to y=x line would be (b,a)
We have point N(-1,2)
-1------>2
2----->-1
so, we get point as
Q=(2,-1)
Answer: The answer is 
Step-by-step explanation: Given that the area of the whole circle is represented by the expression
We are to find the area of the outer ring of the circle, i.e., to find the circumference of the circle.
Now, if 'r' represents the radius of the circle, then we have
Thus, the area of the outer ring is
