Answer: AB = 21
Step-by-step explanation:
Find the value of x by setting them equal to each other
x + 5 = 2x - 11
solve like a normal two step equation
x = 16
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
Answer:
Step-by-step explanation:
The area available to the goat is 3/4 of a circle with 6 ft radius plus 2/4 of a circle with 3 ft radius.
A = (3/4)π*(6 ft)² + (1/2)π*(3 ft)²
= π*((3/4)*36 +(1/2)*9) ft²
= 31.5π ft² ≈ 98.96 ft²
The goat can roam over an area of about 99 ft².
