Answer:
The value of x is 10.5 units.
Step-by-step explanation:
Given:
ABCD is a parallelogram.
AB =
BC =
CD =
We need to find the value of x.
Now the Definition of Parallelogram states that;
"A parallelogram is a quadrilateral with two pairs of parallel sides. The opposite sides of a parallelogram are equal in length and the opposite angles are equal in measure."
Hence from Above definition we can say that;
since these are the opposite sides of parallelogram.
Now Substituting the given values we get;
Now solving the equation we get;
Combining the like terms first.
Now using addition and subtraction property of equality we get;
Now using Division Property we will divide 2 on both side we get;
Hence the value of x is 10.5 units.
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.
