Answer:
3. the correlation between pre-treatment and post-treatment values
Step-by-step explanation:
two treatment groups (A and B). Rats were subcutaneously injected with carrageenan to induce thrombosis. Rats in the treatment group A were intragastrically administered with Huisheng Oral Solution at a dose of 2 ml/100 g body weight (once per 8 hours), 72 hours after carrageenan injection, while those in the treatment group B were administered with Huisheng Oral Solution both 72 hours before and after induction of thrombosis.
The leftmost line segment has a domain of -4 ≤ x < -1, or [-4, 1).
The central line segment has a domain of -1 ≤ x ≤ 2, or [-1, 2].
The rightmost line segment has a domain of 2 < x ≤ 5, or (2, 5].
Overall, this function has a domain of
[-4, 1) U [-1, 2] U (2, 5]
(where U means "union" in the set-theoretic notion)
But this also simplifies to the interval [-4, 5].
These correspond to the <u>first</u> and <u>last</u> choices.
EACH central angle = 360 / number of sides
number of sides = 360 / each central angle
number of sides = 360 / 40
number of sides = 9
Answer:
25×4 + 10×5
He can but 4 reserved seats and 5 general seats.
Step-by-step explanation:
25×4 is 100
10×5 is 50
100+50 is 150 dollars.
