148.41315910= answer is b 148.4
Answer: hope this help u to find the answer
Step-by-step explanation:Combine any like terms on each side of the equation: x-terms with x-terms and constants with constants. Arrange the terms in the same order, usually x-term before constants. If all of the terms in the two expressions are identical, then the two expressions are equivalent.The verbal expression for 2x is: "Two times some value." or "The product of two and some value.
First you have to put it into slope intercept form. You have to put it into y = mx + b then m is the slope and b is the y intercept on the graph.

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
