Answer:
<u>TO FIND :-</u>
- Length of all missing sides.
<u>FORMULAES TO KNOW BEFORE SOLVING :-</u>
<u>SOLUTION :-</u>
1) θ = 16°
Length of side opposite to θ = 7
Hypotenuse = x
≈ 25.3
2) θ = 29°
Length of side opposite to θ = 6
Hypotenuse = x
≈ 12.3
3) θ = 30°
Length of side opposite to θ = x
Hypotenuse = 11
4) θ = 43°
Length of side adjacent to θ = x
Hypotenuse = 12
≈ 8.8
5) θ = 55°
Length of side adjacent to θ = x
Hypotenuse = 6
≈ 3.4
6) θ = 73°
Length of side adjacent to θ = 8
Hypotenuse = x
≈ 27.3
7) θ = 69°
Length of side opposite to θ = 12
Length of side adjacent to θ = x
≈ 4.6
8) θ = 20°
Length of side opposite to θ = 11
Length of side adjacent to θ = x
≈ 30.2
Answer:
We conclude that the mean number of residents in the retirement community household is less than 3.36 persons.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 3.36
Sample mean, = 2.71
Sample size, n = 25
Alpha, α = 0.10
Sample standard deviation, s = 1.10
First, we design the null and the alternate hypothesis
We use One-tailed(left) t test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and fail to accept it.
Thus, we conclude that the mean number of residents in the retirement community household is less than 3.36 persons.
Answer:
If two lines intersect, then there is one plane
that contain(s) them
Step-by-step explanation:
According to the plane-line postulate, if two points lie in a plane, the line containing them lies on the plane.According to the line intersecting theorem, if two lines intersect, then exactly one plane contains both lines.This should be the line-intersecting theorem.
