Can the following quadrilateral be proven to be a parallelogram based on the given information? Explain.
(picture shown below)
A.) No. It cannot be proven because at least two of the adjacent angles are not congruent to each other
B.) Yes. It can be proven because both pairs of opposite sides are congruent.
C.) No. It cannot be proven because it does not have an angle that is supplementary to both of its consecutive angles.
D.) Yes. It can be proven because both pairs of opposite angles are congruent.
Answer:
Step-by-step explanation:
The answer is, no!
Step-by-step explanation:
The reason to that answer is that some other shapes are also, having the same properties as shown. An example for that property would also mean a rectangle and not always a parallelogram.
So, here is the given information on what we need to classify a shape as a parallelogram:-
1) Parallel Sides
2)Opposite Sides are equal.
3) Adjacent sides are not equal.
4) Opposite angles are equal.
5)Adjacent angles are not equal.
Based on this, we can classify a shape as a parallelogram.

The 1057 houses she surveyed have a mean price of $169 comma 400, with a standard deviation of $ 68 comma 438. The mean living area is 2058 sq ft, with a standard deviation of 790 sq ft. Which is more unusual, a house in that market that sells for $300 comma 000 or a house that has 3000 sq ft of living area? Explain. Choose the correct answer below. The house that sells for $300 comma 000 has a z-score of nothing and the house with 3000 sq ft has a z-score of nothing. Thus, a house in that market that ▼ sells for $ 300 comma 000 has 3000 sq ft of living area is more unusual than a house that ▼ sells for $ 300 comma 000 has 3000 sq ft of living area .
Answer:
A a house in that market that sells for $300,000 is unusual.
Step-by-step explanation:
Let the random variable X denote the price of a house and the random variable Y denote the living area of a house.
The number of houses surveyed by the real estate agent is, n = 1057.
Assume that both the random variables, X and Y are approximately normally distributed.
That is,
\(X\sim N(\$169400,\ \$68438)\\\\Y\sim N(2058\ \text{sq. ft.},\ 790\ \text{sq. ft.})\)
To compute the probability of a Normal distribution we first need to convert the raw scores to z-scores.
\(z=\frac{\text{Raw score}-\mu}{\sigma}\)
A z-score higher than 1.96 and lower than -1.96 are considered unusual. The values having these z-scores are considered as outliers.
(1)
Compute the z-score for X = 300000 as follows:
\(z=\frac{X-\mu}{\sigma}\\\\=\frac{300000-169400}{68438}\\\\=2.70\)
(2)
Compute the z-score for Y = 3000 as follows:
\(z=\frac{Y-\mu}{\sigma}\\\\=\frac{3000-2058}{790}\\\\=1.19\)
The z-score for a house in that market that sells for $300,000 is more than 1.96.
This implies, that the price $300,000 is unusually high.
The complete statement is:
The house that sells for $300 comma 000 has a z-score of 2.70 and the house with 3000 sq ft has a z-score of 1.19.

Solve for a and b.
Simplifying
10x + -8 = ax + b
Reorder the terms:
-8 + 10x = ax + b
Solving
-8 + 10x = ax + b
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1ax' to each side of the equation.
-8 + -1ax + 10x = ax + -1ax + b
Combine like terms: ax + -1ax = 0
-8 + -1ax + 10x = 0 + b
-8 + -1ax + 10x = b
Add '8' to each side of the equation.
-8 + -1ax + 8 + 10x = 8 + b
Reorder the terms:
-8 + 8 + -1ax + 10x = 8 + b
Combine like terms: -8 + 8 = 0
0 + -1ax + 10x = 8 + b
-1ax + 10x = 8 + b
Reorder the terms:
-8 + -1ax + -1b + 10x = 8 + b + -8 + -1b
Reorder the terms:
-8 + -1ax + -1b + 10x = 8 + -8 + b + -1b
Combine like terms: 8 + -8 = 0
-8 + -1ax + -1b + 10x = 0 + b + -1b
-8 + -1ax + -1b + 10x = b + -1b
Combine like terms: b + -1b = 0
-8 + -1ax + -1b + 10x = 0

You want to restrict the domain of the function shown in the graph below to make it one-to-one so that it will have an inverse. What are the largest domains, in interval notation you could use
Answer:
(-∞, -3] or [-3, ∞)
Step-by-step explanation:
You want the largest domain interval(s) on which the function shown in the graph could be one-to-one.
One-to-oneA one-to-one function must pass the horizontal line test. That is, no horizontal line can intersect its graph in more than one place.
ApplicationFor that to be true of the given function, the interval on which it is defined cannot include values on both sides of x=-3, where the graph has a minimum. That is, the domain must be either x ≤ -3, or x ≥ -3, (or some subset of either of these).
The largest intervals on which the function has an inverse are ...
(-∞, -3] or [-3, ∞)
<95141404393>
To make the given function one-to-one and have an inverse, we can restrict its domain to (-∞, a) or (a, ∞), where 'a' is the x-coordinate of the highest or lowest point on the graph.
Explanation:To make the given function one-to-one and have an inverse, we need to restrict its domain. The largest domains, in interval notation, that can be used are: (-∞, a) or (a, ∞) where 'a' is the x-coordinate of the highest or the lowest point on the graph, depending on the function type.
If the graph has a highest point, the domain is restricted to (a, ∞), where 'a' is the x-coordinate of the highest point. If the graph has a lowest point, the domain is restricted to (-∞, a), where 'a' is the x-coordinate of the lowest point.
For example, if the graph has a highest point at (3, 5), the domain would be restricted to (3, ∞) to make the function one-to-one and have an inverse.

If 12 kilograms of meat costs R30.00, the unit price per kilogram is B. R2.50.
What is the unit price?The unit price refers to the price charged for an item or a measurement unit of the item.
For example, a unit price may be based on a kilogram or pint. The unit price can also be based on other measurement units, like a pound, a meter, a kilometer, etc.
The number of kilograms of meat bought = 12 kilograms
The total cost of 12 kilograms of meat = R30.00
The unit price of each kilogram of meat = R2.50 (R30.00 ÷ 12)
Thus, the unit price is found as the quotient of the total cost and the total number of items purchased or sold.

If the claim is true, in a sample of 160
batteries, what is the probability that the mean battery life would be greater than 553.9
minutes? Round your answer to four decimal places.
As a result, the probability that the average battery life exceeds 553.9 minutes is 0.0262 (or 2.62%). The answer, rounded to four decimal places, is 0.0262.
What is probability?Probability serves as an indicator of how likely an event is to occur. It is represented by a number between 0 and 1, with 0 representing an unlikely event and 1 representing an unavoidable event. Switching a fair coin and coin flips has a probability of 0.5 or 50% because there are two equally likely outcomes. (Heads or tails). Probability theory is a branch of mathematics that studies happenings rather than their properties. It is applied in many fields, including statistics, fund, science, and engineering.
The central limit theorem can be used to approximate the sample mean distribution as a normal distribution with a mean of the population mean and a standard deviation of the population standard deviation divided by the square root of the sample size.
The standard error of the mean (SE) is calculated as follows:
SE = σ/√n
Where n is the sample size and is the population standard deviation.
SE = 83/√160 = 6.575
Z = (X - μ) / SE
Where X represents the sample mean, is the population mean, and SE represents the standard error of the mean.
Z = (553.9 - 541) / 6.575 = 1.94
As a result, the probability that the average battery life exceeds 553.9 minutes is 0.0262 (or 2.62%). The answer, rounded to four decimal places, is 0.0262.

The multiplication of 4/5 and 10/7 is 8/7 in its simplest form.
To multiply 4/5 by 10/7,
We simply multiply the numerators (4 and 10) to get 40 as the new numerator and multiply the denominators (5 and 7) to get 35 as the new denominator.
Therefore, 4/5 x 10/7 = 40/35.
To simplify this fraction,
We can first find the greatest common factor (GCF) of the numerator and denominator,
Which is 5. We can divide both the numerator and denominator by 5 to get:
40/35 = (5 x 8) / (5 x 7)
= 8/7

It is known that the number of hours a student sleeps per night has a normal distribution. The sleeping time in hours of a random sample of 8 students is given below. See Attached Excel for Data. 8.6, 8.3, 7.6, 6, 7.1, 5.6, 5.1, 6 Compute a 98% confidence interval for the true mean time a student sleeps per night and fill in the blanks appropriately. We have 98 % confidence that the true mean time a student sleeps per night is between and hours. (round to 3 decimal places)
We have 98 % confidence that the true mean time a student sleeps per night is between 6.2928 hours and 7.1832 hours.
Mean = (8.6 + 8.3 + 7.6 + 6 + 7.1 + 5.6 + 5.1 + 6)/ 8 = 6.7875
Standard deviation = √Σ(x - mean)²/n
Σ(x - mean)² = (8.6 - 6.7875)^2 + (8.3 - 6.7875)^2 + (7.6 - 6.7875)^2 + (6 - 6.7875)^2 + (7.1 - 6.7875)^2 + (5.6 - 6.7875)^2 + (5.1 - 6.7875)^2 + (6 - 6.7875)^2

s = 0.42991
Confidence interval is written in the form,
(Sample mean - margin of error, sample mean + margin of error)
The sample mean, x is the point estimate for the population mean.
Margin of error = z × s/√n
Where
sample standard deviation
number of samples
From the information given, the population standard deviation is unknown and the sample size is small, hence, we would use the t distribution to find the z score
In order to use the t distribution, we would determine the degree of freedom, df for the sample.
df = n - 1 = 8 - 1 = 7
Since confidence level = 98% = 0.98, α = 1 - CL = 1 - 0.98 = 0.02
α/2 = 0.02/2 = 0.01
the area to the right of z0.01 is 0.01 and the area to the left of z0.01 is 1 - 0.01 = 0.99
Looking at the t distribution table,
z = 2.998
Margin of error = 2.998 × 0.42/√8
= 0.4452
The lower limit of this confidence interval is

The two lines are neither parallel nor perpendicular.
What is condition for perpendicular, parallel?
if two given lines are parallel, perpendicular, or neither, we need to compare their slopes. For this, we need to make sure that their equations are in the form y = mx + b. This represents the equation of a straight line in the slope-intercept form, where m is the slope and b is the y-intercept.
If the given lines have the same slope, they’re parallel to one another. On the other hand, if they have slopes that are opposite reciprocals, i.e., the slopes have opposite signs and are flipped fractions of one another, they are perpendicular to each other. Else, they are neither.
The given lines are
- 3x + 6y = 12 or, y = (1/2)x + 2 ... (1)
y = - 3x + 10 ... (2)
The gradient of the lines (1) and (2) are 1/2 and (- 3) respectively.
Since the gradients are not equal, the lines are not parallel and also since (1/2) × (- 3) ≠ - 1, the lines are not perpendicular to each other.

the sum of four consecutive odd numbers is 48?
Answer:
The numbers are 9 + 11 + 13 + 15.
Step-by-step explanation: The equation for this is simple.
Take x as the smallest number of the 4 numbers. The second number would be x +2, third number is x+4, and the fourth number is x+6. you add these together, and you get: 4x +12 = 48, you then solve this as a linear equation. 48-12 = 36. Then you divide by 4, which gives you 9 as the smallest number of the 4 numbers. Remember that the second number is 9+2=11, third is 9+4=13, and the fourth is 9+6=15. If you add these together you get 9+11+13+15=48.
6. Rewrite y = √√4x+16 +5 to make it easy to graph using a translation. Describe the graph.
Answer:
~
Step-by-step explanation:
To make it easier to graph using a translation, we can rewrite the given equation as:
y - 5 = √√4x + 16
This is obtained by subtracting 5 from both sides of the equation.
The graph of the original equation y = √√4x+16 +5 can be obtained by taking the graph of y = √√4x + 16 and shifting it upwards by 5 units. The graph of y = √√4x + 16 is a square root function that has a vertical stretch of 2, a horizontal compression of 4, and a vertical translation of 16 units upwards. So the graph of the given equation y = √√4x+16 +5 will be the same as the graph of y = √√4x + 16, but shifted upwards by 5 units.
Consider a circle whose equation is x2 + y2 – 2x – 8 = 0. Which statements are true? Select three options.
The radius of the circle is 3 units.
The center of the circle lies on the x-axis.
The center of the circle lies on the y-axis.
The standard form of the equation is (x – 1)² + y² = 3.
The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
The three statements that are true include the following:
A. The radius of the circle is 3 units.
B. The center of the circle lies on the x-axis.
D. The radius of this circle is the same as the radius of the circle whose equation is x² + y² = 9.
What is the equation of a circle?In Mathematics, the standard form of the equation of a circle is represented by this mathematical expression;
(x - h)² + (y - k)² = r² .......equation 1.
Where:
h and k represents the coordinates at the center of a circle.
r represents the radius of a circle.
Based on the information provided, we have the following equation of a circle:
x² + y² – 2x – 8 = 0 ......equation 2.
In order to determine the true statements, we would rewrite the equation in standard form and then factorize by using completing the square method:
x² – 2x + y² = 8 = 0
x² – 2x + (2/2)² + y² = 8 + (2/2)²
x² – 2x + 1 + y² = 8 + 1
(x – 1)² + (y - 0)² = 9 .......equation 3.
By comparing equation 1 and equation 3, we have the following:
Center (h, k) = (1, 0)
Radius (r) = 3
Additionally, this line and the center of the given circle lies on the x-axis (x-coordinate) because the y-value is equal to zero (0).
(x - 0)² + (y - 0)² = 3²
x² + y² = 9.
