Answer:
b your answer is 0, no need to yell.
So the slope is (y2-y1)/(x2-x1)
(8-4)/(2-1)=
4/1 =
4
Aka. For every 1 week, the number of pictures taken increases by 4.
So it is 4 * w
Check:
4*w = total number of pictures
4*1 = 4
4*2 = 8
4*3 = 12
4*4 = 16
All match the table.
Multiply the quantity in gallons by (3.785 liter/gal) .
The product is the same quantity in liters.
This is a hypergeometric distribution problem.
Population (N=50=W+B) is divided into two classes, W (W=20) and B (B=30).
We calculate the probability of choosing w (w=2) white and b (b=5) black marbles.
Hypergeometric probability gives
P(W,B,w,b)=C(W,w)C(B,b)/(C(W+B,w+b)
where
C(n,r)=n!/(r!(n-r)!) the number of combinations of choosing r out of n objects.
Here
P(20,30,2,5)
=C(20,2)C(30,5)/(20+30, 2+5)
=190*142506/99884400
=0.2710
Alternatively, doing the combinatorics way:
#of ways to choose 2 from 20 =C(20,2)
#of ways to choose 5 from 30=C(30,5)
total #of ways = C(50,7)
P(20,30,2,5)=C(20,2)*C(30,5)/C(50,7)
=0.2710
as before.
Answer:
J + W = T.
Step-by-step explanation:
T would be the total.
