The statement that is true about rhombus is d. some rhombuses have four right angles.

A rhombus is a parallelogram with equal-length sides, though the angles at the opposing ends need not be equal, nor must the sides be parallel. If a rhombus is also a cube, it can have four right angles. It can be viewed as an equal-sided trapezoid as well.

A parallelogram has two sets of parallel sides, whereas a trapezoid only has one pair of parallel sides. Therefore, it is untrue that a trapezoid has two sets of parallel edges. Not all rectangles are squares, but they are all quadrilaterals with four right angles. A unique variety of parallelogram called a square has equal-length edges. Therefore, it is untrue to say that all circles are squares.

Complete Question:

which statement about a quadrilateral is true?

a. a rhombus has exactly one pair of parallel sides.

b. a trapezoid has two pairs of parallel sides.

c. all rectangles are squares.

The probability is 0.9772. The average age of professors at a certain university is normally distributed with an average of 45.0 years and a standard deviation of 6.0 years.

If 16 professors are chosen at random for a committee, find the probability that the average age of those professors is greater than 42.0 years. We are required to find the probability that the average age of the 16 professors is greater than 42 years. Let us consider the mean of sample means as mu_x = 45 years. The standard error of the mean can be calculated as;  standard error = standard deviation/sqrt(n)`where n = sample size.

Standard error = 6.0/sqrt(16) = 1.5. Therefore, z-score is calculated as; z-score = (sample mean - population mean)/standard error = (42-45)/1.5 = -2. Now, the probability of Z being less than -2 can be found from the z-table as P(Z < -2) = 0.0228. So, the probability that the average age of those professors is greater than 42 years is 1- P(Z < -2) = 1- 0.0228 = 0.9772.

Answer:

C, 60 degrees

Step-by-step explanation:

Right Triangle, with a 30 degree angle:
Given degrees:
90 (Right Triangle)
30

90+30 = 120
180-120 = 60

180 Degrees total in a triangle, you simply subtract the measure you have to fidn the third one.

Answer:

The measure of the third angle is 60°.

Step-by-step explanation:

We are given a right triangle that has a 90 degree and two other angles that are unknown.

Since one known angle is 90° and another angle given is 30° then the third angle must be 60°. All triangles must add up to 180°.

180° - 90° -  30° = 60°.

In the ANOVA procedure, the variance observed in the data set is split into various sum of squares. The number of different sum of squares that an ANOVA usually has is three (option a).

These three sum of squares include:

1. Sum of Squares Total (SST):

This represents the total variance in the dataset. It is the sum of the squared differences between each observation and the overall mean of the dataset.

2. Sum of Squares Between (SSB):

This represents the variance between the group means. It is the sum of the squared differences between each group mean and the overall mean, multiplied by the number of observations in each group.

3. Sum of Squares Within (SSW):

This represents the variance within each group. It is the sum of the squared differences between each observation and its respective group mean.

ANOVA uses these sum of squares to determine if there is a significant difference among the group means by comparing the variance between the groups (SSB) to the variance within the groups (SSW).

If the ratio of SSB to SSW is large enough, it indicates that there is a significant difference among the group means, and the null hypothesis can be rejected.

\( \cos 9.28 = \cos \left(\frac{\pi}{187.5}\right) \). we can disregard the \( 4\pi \) term and focus on \( \frac{\pi}{4} \).

a. To express \( \sin \frac{17\pi}{4} \) in terms of \( s \) less than \( 2\pi \) or \( 6.2832 \), we can convert the given angle to an equivalent angle within the range of \( 0 \) to \( 2\pi \).

Since \( 2\pi \) is equivalent to a full revolution (360 degrees), we can subtract multiples of \( 2\pi \) to bring the angle within the desired range:

\( \frac{17\pi}{4} = \frac{16\pi}{4} + \frac{\pi}{4} = 4\pi + \frac{\pi}{4} \)

Now, let's check how many full revolutions we have in \( 4\pi \). Dividing \( 4\pi \) by \( 2\pi \) gives us 2, which means there are two full revolutions. Therefore, we can disregard the \( 4\pi \) term and focus on \( \frac{\pi}{4} \).

\( \frac{\pi}{4} \) corresponds to an angle of 45 degrees (or \( \frac{\pi}{4} \) radians). Since we want the value within the range of \( 0 \) to \( 2\pi \), there is no need for further adjustment.

Hence, \( \sin \frac{17\pi}{4} = \sin \frac{\pi}{4} = \frac{1}{\sqrt{2}} \).

b. To express \( \cos 9.28 \) in terms of \( s \) less than \( 2\pi \) or \( 6.2832 \), we can convert the given angle to an equivalent angle within the desired range.

Since \( 2\pi \) is equivalent to a full revolution (360 degrees), we can subtract multiples of \( 2\pi \) to bring the angle within the range of \( 0 \) to \( 2\pi \):

\( 9.28 = 2(4.64) + 0.96 \)

Since \( 4.64 \) corresponds to \( 2\pi \), we can ignore the \( 2(4.64) \) term and focus on \( 0.96 \).

To convert \( 0.96 \) to radians, we can multiply it by \( \frac{\pi}{180} \) since there are \( 180 \) degrees in \( \pi \) radians:

\( 0.96 \times \frac{\pi}{180} = \frac{\pi}{187.5} \)

Therefore, \( \cos 9.28 = \cos \left(\frac{\pi}{187.5}\right) \).

The fitted model log( ) = 1.6 - 0.2c is equivalent to the models y = 21.6 - 0.25(1+\(e^(1.6-0.2c)\)), y = 1.6 - 0.22/(1+\(e^(1.6+0.2)\)), and y = 1.6 - 0.22.

The fitted model log( ) = 1.6 - 0.2c represents a logarithmic relationship between the dependent variable and an independent variable, denoted as "c." To identify equivalent models, we need to examine the given options.

Option 1: y = 21.6 - 0.25(1+\(e^(1.6-0.2c)\))

This model is equivalent to the fitted model log( ) = 1.6 - 0.2c because the right side of the equation contains the term 1+\(e^(1.6-0.2c)\), which corresponds to the exponential function e^(1.6-0.2c). The coefficient -0.25 in front of the parentheses can be absorbed into the equation without altering its equivalence.

Option 2: y = 1.6 - 0.22/(1+\(e^(1.6+0.2)\))

This model is also equivalent to the fitted model because it contains the term 1+e^(1.6+0.2) in the denominator. The coefficient -0.22 in front of the fraction can be absorbed into the equation without changing its equivalence.

Option 3: y = 1.6 - 0.22

This model is a simplified version of the fitted model. It does not involve any exponential or logarithmic functions, but the coefficients 1.6 and -0.22 remain the same as in the original equation.

Therefore, the correct answers are options 1 and 2, as they preserve the logarithmic nature of the fitted model. Option 3 is not equivalent to the fitted model, as it lacks the logarithmic and exponential components.

Answer:

The equation of the perpendicular bisector of the segment QR (with endpoints Q(-2,0) and R(6,12) is... \(y=-\frac{2}{3}x+\frac{22}{3}\) 

Step-by-step explanation:

01. Review what we know:

We are told that the endpoints of the segment QR is Q(-2,0) and R(6,12).

02. Find the midpoint:

We need to find the coordinates of the midpoint of the segment. The formula for this is \((\frac{x_1+x_2}{2} ,\frac{y_1+y_2}{2})\)

We can do \((\frac{-2+6}{2} ,\frac{0+12}{2})\), which would become \((\frac{4}{2} ,\frac{12}{2})\). This is equal to (2,6), so we know that the midpoint of the segment is at (2,6).

03. Find the slope:

Now, to find the slope of the segment, we must use the formula \(\frac{(y_2-y_1)}{(x_2-x_1)}\)

Using this, we can input the coordinates of Q and R to find the slope.

\(\frac{(0-12)}{(-2-6)}\) would become \(\frac{(-12)}{(-8)}\), which can be simplified to \(\frac{(3)}{(2)}\)

04. Find the slope of the perpendicular bisector:

Whenever we need to find the slope of something perpendicular to the original, we need to take the original slope and find the opposite reciprocal. To find the reciprocal, we would flip the fraction, and to make it opposite, we would make it positive if the original was negative, or negative if the original was positive.

In this case, we would flip \(\frac{3}{2}\) to \(\frac{2}{3}\), and because the original was positive, we would make \(\frac{2}{3}\) negative, into \(-\frac{2}{3}\).

So the slope of the perpendicular bisector is \(-\frac{2}{3}\).

05. Plug in our information to begin to write the equation:

Now, we have all the information we need to begin to form our equation.

Our equation needs to be in the format of y=mx+b, also known as slope-intercept form (m is our slope, b is our y-intercept, and x and y represent the coordinates).

Plugging in our new slope for the perpendicular bisector, we would have \(y=-\frac{2}{3} x+b\)

However, we need to find the y-intercept in order to complete the equation!

06. Finding our y-intercept (aka "b"):

We can do this by plugging in the midpoint coordinates into x and y and solving for b!

We can plug in 2 and 6 into x and y, respectively.

That would give us \(6=-\frac{2}{3} (2)+b\)

Through basic algebra, we can solve this equation.

First we need to multiply \(-\frac{2}{3}\) and \((2)\), which gives us \(-\frac{4}{3}\)

Then, we need to isolate b, which we can do by adding \(\frac{4}{3}\) on both sides of the equation.

\(6=-\frac{4}{3}+b\\+\frac{4}{3}+\frac{4}{3}\\\) (<-- like this)

This would cancel \(-\frac{4}{3}\) out on the right side and move it to the left side, giving us \(6+\frac{4}{3}=b\)

Now, we need to add \(6+\frac{4}{3}\), which we can do by finding the common denominator of both. \(6=\frac{6}{1}\), and \(\frac{6}{1} *3=\frac{18}{3}\)

Now they share the same denominator, and we can add them together. \(\frac{4}{3} +\frac{18}{3}=\frac{22}{3}\), so the y-intercept, or "b," is \(\frac{22}{3}\)

07. Add the y-intercept to the equation:

Now that we have our y-intercept, we can finalize our equation!

\(y=-\frac{2}{3} x+b\) becomes \(y=-\frac{2}{3} x+\frac{22}{3}\) when we add in the y-intercept.

Now we have our equation for the perpendicular bisector of QR! Our answer is \(y=-\frac{2}{3} x+\frac{22}{3}\)

The equation of f(x) from the graph if, G(x) = x², is F(x) = 2x² + 3, so option A is correct.

A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.

Given:

G(x) = x²,

As you can see from the graph, the vertex of the parabola is (0, 3),

Write the equation of a parabola as shown below,

y = a(x - 0)² + 3

y = ax² + 3

Here a is the slope of the parabola,

slope = 4 / 2  (from the graph),

slope = 2

Lara will be paying the total amount is $5310

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.

Given that, Lara borrowed $4500 for some home repairs. She will be paying 6% in simple interest over the next three years.

We need to find the total amount she will be paying on the loan,

So, the formula for simple interest is - SI = PRT / 100

P = principal, r = rate and t = time

Therefore,

SI = 4500 x 6 x 3 / 100

= 45 x 18 = 810

The interest = $810

She will pay = interest + principal = 810 + 4500 = $5310

Hence, Lara will be paying the total amount is $5310
