Answer:
24.03 units (nearest hundredth)
Step-by-step explanation:
The distance between B and A is: AB = AH + HB
We have been given AH, so we just need to find the measure of HB.
First, find the angle AOH using tan trig ratio:
where:
is the angle- O is the side opposite the angle
- A is the side adjacent the angle
Given:
- = ∠AOH
- O = AH = 8
- A = OH = 19.80
∠BOA = ∠BOH + ∠AOH
⇒ ∠BOH = ∠BOA - ∠AOH
⇒ ∠BOH = 61° - 22.00069835°
= 38.99930165°
Now we can find HB by again using the tan trig ratio:
Given:
- = ∠BOH = 38.99930165°
- O = HB
- A = OH = 19.80
Substituting given values:
Therefore:
AB = AH + BH
⇒ AB = 8 + 16.03332427
= 24.03 units (nearest hundredth)
Answer:
The fraction which would represent this question is 
Step-by-step explanation:
The way to represent a division problem as a fraction is to put the dividend (3) over the divisor (5).
Answer:
e. Two-sample t-test.
Step-by-step explanation:
This is simply because you only have interval level of measure and you are comparing two populations.
Moreso, this hypothesis test is used to determine questions related to the mean in situations where data is collected from two random data samples. The two sample T-test is often used for evaluating the means of two variables or distinct groups, providing information as to whether the means between the two populations differs. It also can be used to compare the responses of males and females who have each received different treatment within an experiment.
Answer:
Step-by-step explanation:
Step 1. Switch sides.
Step 2. Since the fraction 1/2 multiplies b, multiply both sides by the reciprocal of 1/2 which is 2.
Step 3. Since h is multiplying b, and you want b alone, divide both sides by h.
