Answer:
Step-by-step explanation:
(x-2)/2 = -3
x - 2 = -6
x = -4
(y + 2)/2 =4
y + 2 =8
y = 6
(-4, 6)
It'd be best if you were to enclose that fraction 4/3 inside parentheses:
<span>2>8−(4/3)h
Mult. all 3 terms by 3: 6>24 -4h
Add 4h to both sides: +4h +4h
------------------
7+4h > 24
Subtract 7 from both sides: -7 -7
------------------
4h > 17
Then h>17/4 (answer) Note: We want h to be positive. That's why I moved (-4/3)h to the other side of the = sign.</span>
If about 20% of British children are deficient in vitamin and doctors test a group of elementary school children, the probability that the first vitamin d-deficient child is the 8th one tested is 4.19% determined using geometric distribution formula.
In probability and statistics, geometric distribution refers to the probability that first success would occurs after n number of trials and is given by:
P(X)=q^(x-1)p
Where p is the probability of success and q is (1-p)
In this case,
p=probability of children deficient in vitamin= 0.2
q= probability of children not deficient in vitamin= 0.8
Hence,
P(8)=0.8^(8-1)*0.2= 0.0419
Hence, the probability that 8th child is deficient is 4.19%

Answer:
C |p| = 4
Step-by-step explanation:
If a player wins 4points during each turn, then, the total points will be +4points
If the player looses 4points, total points lost will be -4points
The total number of point p the player can have will be represented as;
|p| = 4 (since is both positive and negative 4 )
Note that the nodulus of a variable will return both positive and negative value of that variable
3(3-y)+1=31
9-3y+1=31
10-3y=31
-3y=31-10
-3y=21
y=-21/3 = -7
the solution is y=-7
