Answer:
(A) 0.377,
(B) 0.000,
(C) 0.953,
(D) 0.047
Step-by-step explanation:
We assume that having a bone of intention means not liking one's Mother-in-Law
(A) P(all six dislike their Mother-in-Law) = (85%)^6 = (.85)^6 = 0.377
(B) P(none of the six dislike their Mother-in-Law) =
(100% - 85%)^6 =
0.15^6 =
0.000
(C) P(at least 4 dislike their Mother-in-Law) =
P(exactly 4 dislike their Mother-in-Law) + P(exactly 5 dislike their Mother-in-Law) + P(exactly 6 dislike their Mother-in-Law) =
C(6,4) * (.85)^4 * (1-.85)^2 + C(6,5) * (.85)^5 * (.15)^1 + C(6,6) * (.85)^6 = (15) * (.85)^4 * (.15)^2 + (6) * (.85)^5 * .15 + (1) * (.85)^6 =
0.953
(D) P(no more than 3 dislike their Mother-in-Law) =
P(exactly 0 dislikes their Mother-in-Law) + P(exactly 1 dislikes her Mother) + P(exactly 2 dislike their Mother-in-Law) + P(exactly 3 dislike their Mother-in-Law) =
C(6,0) * (.85)^0 * (.15)^6 + C(6,1) * (.85)^1 * (.15)^5 + C(6,2) * (.85)^2 * (.15)^4 + C(6,3) * (.85)^3 * (.15)^3 =
(1)(1)(.15)^6 + (6)(.85)(.15)^5 + (15)(.85)^2 *(.15)^4 + (20)(.85)^3 * (.15)^3 =
0.047
Answer:
It's D
Step-by-step explanation:
2t - 30(
) = 20
2t - 
() = 20
2t - 
= 20
2t - 6 = 20
2t - 6 + 6 = 20 +6
2t = 26
= 
t = 13
Answer:
2.15
Step-by-step explanation:
Let g= cost of granola bars
b = cost of bottles of water
10g+12b =23
5g +4b = 10
I will solve this system by elimination
Multiply the second equation by -2
-2(5g +4b) = -2*10
-10g -8b = -20
Now we add this equation to the first equation to eliminate g
-10g -8b = -20
10g+12b =23
---------------------
4b = 3
b = 3/4
A bottle of water = $.75
Now we need to find g
5g+4b =10
5g +4(.75) = 10
5g +3 = 10
Subtract 3 from each side
5g +3-3 = 10-3
5g =7
Divide by 5
5g/5=7/5
g = 7/5
g = 1 2/5
g =1.40
We want the cost of one bottle of water and 1 granola bar
1g + 1b
1.4+.75
2.15
Answer:
I think its D
Step-by-step explanation:
Because if it was standing still the line would be vertical. And its moving way from the starting point and its moving at a constant speed because its increasing
