Answer:
SAS
Step-by-step explanation:
the correct answer is side angle side (SAS)
Answer:
see explanation
Step-by-step explanation:
Using the chain rule and the standard derivatives
Given
y = f(g(x)) , then
= f'(g(x)) × g'(x) ← chain rule
(tanx) = sec²x , (cotx) = - csc²x
(c)
y = tan = tan
= sec² × ( )
= sec² ×
= sec² ×
=
(d)
y = cot(1 + x)
= - csc²(1 + x) × (1 + x)
= - csc²(1 + x) × 1
= - csc²(1 + x)
I believe it would be 25% because you have a 1/4th chance of rolling tails twice
Answer: 0.16
Step-by-step explanation:
Given that the run times provided are normally distributed ;
Mean(x) of distribution = 3 hours 50 minutes
Standard deviation(s) = 30 minutes
The probability that a randomly selected runner has a time less than or equal to 3 hours 20 minutes
3 hours 20 minutes = (3 hrs 50 mins - 30 mins):
This is equivalent to :
[mean(x) - 1 standard deviation]
z 1 standard deviation within the mean = 0.84
z, 1 standard deviation outside the mean equals:
P(1 - z value , 1standard deviation within the mean)
1 - 0.8413 = 0.1587
= 0.16
