Answer:
4
Step-by-step explanation:
A false statement implies a true statement,so the conditional statement is false.
Answer:
(x+1)^2 = x^2 + 2x +1
so b =2
Step-by-step explanation:
You would use the Law of Sines here. First realize that if A and B equal 35 and 65 respectively, C=180-65-35=80°. Then from the Law of Sines:
b/sin65=15/sin80
b=15sin65/sin80
b≈13.8 units (to the nearest tenth of a unit)
Answer:
Step-by-step explanation:
The square root of 16 is 4, which is less than 4.001
Answer: 0.9746
Step-by-step explanation:
Given : A normally distributed population has a mean of 250 pounds and a standard deviation of 10 pounds.
i.e.
Sample size : n= 20
Let sample mean values.
Then, the probability that this sample will have a mean value between 245 and 255 be
Hence , the probability that this sample will have a mean value between 245 and 255 is 0.9746 .
