Write the inequality in interval notation and graph.
Answers
The inequality in interval notation is [ -1, ∞ ) from the given equation x ≥ - 3
What is interval notation ?Continuous sets of real numbers can be represented using interval notation by the numbers that bound them. When written, intervals resemble ordered pairs in several ways. They do not, however, intend to indicate any particular location. Instead, they serve as a concise approach to express an inequality or a set of inequalities.A set of real numbers known as an interval in mathematics contains all real numbers falling inside any two of the set's numbers. For instance, the interval containing 0, 1, and all integers in between is the set of values x satisfying 0 x 1.a collection of all real numbers. The interval notation (,) can be used to denote a function's domain as only real values.Given data :
x ≥ - 3
x is greater than or equal to - 3, so - 3 is our smallest value of the interval so it goes on the left. Since there is no upper endpoint (it is ALL values greater than or equal to 3),
we put the infinity symbol on the right side. The boxed end on 3 indicates a closed interval.
In interval notation it is [ -1, ∞ )

Part B: Calculate the measures of variability. Show all work. (1 point)
Part C: If you are interested in a smaller class size, which school is a better choice for you? Explain your reasoning. (1 point)
Answers
Part A: The mean and median for Bay Side School are 3.8 and 5, respectively, while for Seaside School they are 4.93 and 5.
Part B: The range and IQR for Bay Side School are 8 and 4, respectively, while for Seaside School they are 8 and 2.
Part C: Bay Side School is a better choice for smaller class sizes due to its smaller mean, smaller range, and larger IQR.
Part A: Measures of Center
Bay Side School:
Mean = 3.8 (The sum of all class sizes divided by the number of classes)
Median = 5 (The middle value when class sizes are arranged in ascending order)
Seaside School:
Mean = 4.93 (The sum of all class sizes divided by the number of classes)
Median = 5 (The middle value when class sizes are arranged in ascending order)
Part B: Measures of Variability
Bay Side School:
Range = 8 (The difference between the maximum and minimum class sizes)
Interquartile Range (IQR) = 4 (The difference between the first quartile and third quartile)
Seaside School:
Range = 8 (The difference between the maximum and minimum class sizes)
Interquartile Range (IQR) = 2 (The difference between the first quartile and third quartile)
Part C: Conclusion and Reasoning
If you are interested in a smaller class size, Bay Side School is a better choice. Bay Side School has a smaller mean (3.8) compared to Seaside School (4.93), indicating a generally smaller class size. Additionally, the median class size is the same for both schools, but the range and IQR are smaller for Bay Side School.
This suggests that class sizes at Bay Side School have less variation and are more consistently smaller. Therefore, based on the provided data, Bay Side School is the better choice for smaller class sizes.

What is the length of the fence around the enclosure not including the gates?
Answers
The length of the fence around the enclosure not including the gates is:2l + 2w + 8 m
To find the length of the fence around the enclosure, we need to first find the perimeter of the rectangle and then subtract the combined length of the two gates from it.
Let's assume the length of the rectangle is 'l' and the width is 'w'.
From the given data, we know that each gate is 4 m wide.
Therefore, the width of the rectangle is:
Width = w + (4 m + 4 m) = w + 8 m
The perimeter of the rectangle is:
P = 2l + 2(w + 8 m) = 2l + 2w + 16 m
Now, we need to subtract the combined length of the two gates from the perimeter:
P - 2 × 4 m = 2l + 2w + 16 m - 8 m = 2l + 2w + 8 m
So, the length of the fence around the enclosure not including the gates is:2l + 2w + 8 m

If the width of the compass changed, it would make the arc smaller or larger. This would then make the line segment to be drawn smaller or larger, so it would not match the original.
Step-by-step explanation:
We assume your construction is trying to copy the length of a line segment. That length is "measured" by the width of the compass. If it is changed, it no longer matches the length of the segment you're trying to copy, so you will not get the copy you want.

The reason why is because of the proportions to each intersection of linesare equal to each other (each is SIMILAR, like forming a triangle). In this case, they will both end up having the same fraction but in different form.
So, for the smaller set on the right the fraction is 8.5/5, meaning the fraction is width/height.
The same will go for the left one: width/height. This means that the left will be 29/h.
So, the answer is J. 29/h=8.5/5.

Find the interest.
Periodic Deposit is $6000 at the end of each year
Rate 5% compounded annually
Time 10 years
a. The value of the annuity is $
b. The interest is $
Answers
The value of the annuity is approximately $79,243.59, and the Interest earned is $19,243.59.
The value of the annuity and the interest earned, we can use the formula for the future value of an ordinary annuity.
The formula for the future value of an ordinary annuity is:
V = P * [(1 + r)^n - 1] / r
Where:
V is the value of the annuity
P is the periodic deposit
r is the interest rate per period
n is the number of periods
In this case:
P = $6000 (periodic deposit)
r = 5% (interest rate per period, compounded annually)
n = 10 years (number of periods)
a. To find the value of the annuity:
V = $6000 * [(1 + 0.05)^10 - 1] / 0.05
V ≈ $79,243.59
Therefore, the value of the annuity is approximately $79,243.59.
b. To find the interest earned:
Interest = V - (P * n)
Interest = $79,243.59 - ($6000 * 10)
Interest = $79,243.59 - $60,000
Interest = $19,243.59
Therefore, the interest earned is $19,243.59.
In summary, the value of the annuity is approximately $79,243.59, and the interest earned is $19,243.59.

4. RSTU is a trapezoid because the opposite sides RS and UT are parallel.
5. RSTU is not an isosceles trapezoid because the diagonals are not congruent.
How to verify that RSTU is a trapezoid?In order to verify that RSTU is a trapezoid, we would have to determine slope of the pair of opposite sides and check whether at least one pair of opposite sides are parallel;
RU ║ ST
Slope of side RU = Slope of side ST
Slope of RU = (y₂ - y₁)/(x₂ - x₁)
Slope of RU = (1 + 3)/(5 + 3)
Slope of RU = 4/8
Slope of RU = 0.5.
Slope of RS = (y₂ - y₁)/(x₂ - x₁)
Slope of RS = (-9 + 3)/(-4 + 3)
Slope of RS = -6/-1
Slope of RS = 6.
Slope of ST = (y₂ - y₁)/(x₂ - x₁)
Slope of ST = (-2 - 1)/(10 - 5)
Slope of ST = -3/5
Slope of ST = -0.6.
Slope of UT = (y₂ - y₁)/(x₂ - x₁)
Slope of UT = (-2 + 9)/(10 + 4)
Slope of UT = 7/14
Slope of UT = 0.5.
Therefore, RSTU is a trapezoid because the opposite sides RS and UT are parallel.
Question 5.
In order to determine whether RSTU is an isosceles trapezoid, we would have to determine length of the diagonals by using the distance formula and check whether they are congruent;
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance RT = √[(-2 + 3)² + (10 + 3)²]
Distance RT = √170 units.
Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]
Distance US = √[(5 + 4)² + (1 + 9)²]
Distance US = √181 units.
Therefore, RSTU is not an isosceles trapezoid because the diagonals RT and US are not congruent.
