Answer:
B And D
Step-by-step explanation:
B is for the number of donuts
D is for the cost of donuts
She needs 6 packages. 4(1/4)=1 + 1/4+1/4=1/2.
Answer:
a= 1/2 and b= 1/2
Step-by-step explanation:
The given probability can be expressed in the form of binomial expansion where a= p and b= q
Therefore a= 1/2 and b= 1/2
For n= 8 trials the binomial expansion can be written as
[ p+q] ^n = [ 1/2+1/2]^8
=(1/2)^0(1/2)^8 +8C1(1/2)^7(1/2)+8C2(1/2)^6(1/2)^2+8C3(1/2)^5(1/2)^3+8C4(1/2)^4(1/2)^4+8C5(1/2)^3(1/2)^5+8C6(1/2)^2(1/2)^6+8C7(1/2)(1/2)^7+8C8(1/2)^0(1/2)^8
=
1(1/2)^0(1/2)^8 +8(1/2)^7(1/2)+28(1/2)^6(1/2)^2+56(1/2)^5(1/2)^3+70(1/2)^4(1/2)^4+56(1/2)^3(1/2)^5+28(1/2)^2(1/2)^6+8(1/2)(1/2)^7+1(1/2)^0(1/2)^8
=
1/(2)⁸ { 1+ 8+28+56+70+56+28+8+1}
= 1/(2)⁸ {256}
= 1
The total probability is always 1.
Also P+q= 1
1/2+1/2= 1
Answer:
0.625N
Step-by-step explanation:
0.50N
0.80M = 0.50N, so M = ------------
0.80
and so:
0.50N
N*M = N*------------ = (5/8)N, or 0.625N
0.80
Answer:
![A=\displaystyle\frac{1}{2} bh](https://tex.z-dn.net/?f=A%3D%5Cdisplaystyle%5Cfrac%7B1%7D%7B2%7D%20bh)
Step-by-step explanation:
Hi there!
Let <em>A</em> be equal to the area of a triangle.
Let <em>b</em> be equal to its base.
Let <em>h</em> be equal to its height.
We're given that the area (A) is equal to 1/2 of its base (b) times its height (h):
![A=\displaystyle\frac{1}{2} bh](https://tex.z-dn.net/?f=A%3D%5Cdisplaystyle%5Cfrac%7B1%7D%7B2%7D%20bh)
I hope this helps!
