Answer:
The slope is 1/2
Step-by-step explanation:
m=y²-y¹/x²-x¹
m=2-1/4-2
m=1/2
1:
3*3=8 ;
8*3=23
23*3=68
68*3=204
1.3,8,23,68,204 ...
2.
2*3=6
6*3=18
18*3=54
2, 6,18,54
multiply all on 3)
1. Volume of the sphere

Choice c
2. Algebra making a token effort to pretend to be geometry. Complementary angles add to 90 degrees.
(x+1) + (x-3)=90
2x -2 = 90
2x = 92
x = 46
Angles x+1=47 and x-3=43
Choice b
3. midpoint A=-5, E=5
The midpoint is just the average of A and E, here zero, point D
choice b
4. I can't really tell if x is supposed to be an angle or a length in this figure; presumably a length. I suppose we're to assume parallel lines; so this makes similar shapes, i.e. a proportionality:


Choice a
Answer:

Step-by-step explanation:
If the probability of having a boy or a girl is the same, then
the probability of having a boy = a probability of having a girl = 1/2.
Let B denote boy and G denote the girl.
The sample space of having three children is:
BBB, BBG, BGB, GBB, BGG, GBG, GGB, GGG.
The probabilities of each of those events is
