Answer:
The translated function is g(x)= 1/x+2 +3
Step-by-step explanation:
$22x5% = $1.10 or 22x.05= 1.1
$22.00 + $1.10 = $23.10
Let the unknown number be x. Then (1/10)x = 0.002. To solve for x, multiply both sides by 1000 to remove the decimal fraction 0.002.
Then 1000(1/10)x = 1000(0.002), or 100x = 2. Dividing both sides by x returns
x=100/2, or x= 50 (answer)

Answer:
AB
Step-by-step explanation:
If blood type is independent of gender then we must have for each blood type 50% males and 50% females
Let us compare with this view each blood type
A
Observed 105 93 198 105 93 198
Expected 99 99 198 99 99 198
(O-E)^2 36 36 72
(O-E)^2/E 0.363636364 0.363636364 0.727272727
B
Observed 105 93 198 99 84 183
Expected 99 99 198 91.5 91.5 183
(O-E)^2 56.25 56.25 112.5
(O-E)^2/E 0.614754098 0.614754098 1.229508197
AB
Observed 15 18 33
Expected 16.5 16.5 33
(O-E)^2 2.25 2.25 4.5
(O-E)^2/E 0.136363636 0.136363636 0.272727273
O
Observed 160 140 300
Expected 150 150 300
(O-E)^2 100 100 200
(O-E)^2/E 0.666666667 0.666666667 1.333333333
We find that the deviations are the least for blood group AB
So AB blood group is independent of gender
