Going upstream takes longer because of the flow of the water
Answer:
110 degrees, 84 degrees
Step-by-step explanation:
Picture 1:
See attached image for the angles I am referencing.
measure of angle a= measure of the 110 degree angle because of corresponding angles
measure of angle b=measure of angle a because of vertical angles
Therefore, through transitivity, we can state that the measure of
angle b= angle a= 110 degrees
Picture 2:
angle x=84 degree angle through alternate interior angles.
Answer:
The length of AB = 17
Step-by-step explanation:
AB = √[(10-2)^2 + (4-19)^2]
AB = √(64 + 225)
AB = √289
AB = 17
We have the identity

Take the square root of both sides and rearrange terms on the right to get

Decrementing n gives

and substituting the previous expression into this, we have

Continuing in this fashion, after k steps we would have

After a total of n - 2 steps, we arrive at

Then as n goes to infinity, the first nested radical converges to √x + 1/4. Similar reasoning can be used to show the other nested radical converges to √x - 1/4. Then the integral reduces to

Answer:
the probability of a Type I error is 0.10
Step-by-step explanation:
Given the data in the question;
significance level ∝ = 0.10
Null H₀ hypothesis is true;
the probability of a Type I error = ?
we know that; a type 1 error is the error of rejecting a Null hypothesis when in reality, it is true. That is false positive.
Hence, our type 1 error will be;
P(rejecting null | null true ) = significance level ∝ = 0.10
Therefore, the probability of a Type I error is 0.10
