Answer:
a = 2
b = 3
c = 2³ or 8
Step-by-step explanation:
Exponent Rule:
log₂(4) = 2 or 2² = 4
2⁵/2² = 2³
2³ = 8
Answer:
Y=106
X=18
Step-by-step explanation:
Both sides would have 65° because of the Alternet interior angles.
180° minus the 65° gives you 115° when you solve for X and solve for Y Use the 115° as shown in the photo below
Complete Question:
a) Is it plausible that X is normally distributed?
b) For a random sample of 50 such pairs, what is the (approximate) probability that the sample mean courtship time is between 100 min and 125 min?
Answer:
a) It is plausible that X is normally distributed
b) probability that the sample mean courtship time is between 100 min and 125 min is 0.5269
Step-by-step explanation:
a)X denotes the courtship time for the scorpion flies which indicates that is a real - valued random variable, and since normal distribution is a continuous probability distribution for a real valued random variable, it is plausible that X is normally distributed.
b) Probability that the sample mean courtship time is between 100 min and 125 min
From the probability distribution table:
