7. Quadrilateral MNPQ has vertices M(4,0), N(0,6), P(-4,0) and Q(0, -6). Determine whether
MNPQ is a parallelogram, a rhombus, a rectangle, a square, or a quadrilateral. Choose the most
specific term. Show work.
Answers
Answer:
SQUARE
Step-by-step explanation:
If Quadrilateral MNPQ has vertices M(4,0), N(0,6), P(-4,0) and Q(0, -6).
Find the following MN, NP, PQ and MQ
Using the formula for calculating the distance between two points
MN = √(6-0)²+(0-4)²
MN = √6²+4²
MN = √36+16
MN = √52
MN = 2√13
NP = √(0-6)²+(-4-0)²
NP = √6²+4²
NP = √36+16
NP = √52
NP = 2√13
PQ = √(-6-0)²+(0-(-4))²
PQ = √6²+4²
PQ = √36+16
PQ = √52
PQ = 2√13
MQ = √(-6-0)²+(0-4)²
MQ = √6²+4²
MQ = √36+16
MQ= √52
MQ = 2√13
Since the length of all the sides are equal, hence the shape is a SQUARE

The number of bacteria in a culture is increasing according to the law of exponential growth. There are 135 bacteria in the culture after 2 hours and 385 bacteria after 4 hours.. use the model to determine the number of bacteria after 8 hours. (round your answer to the nearest whole number.)
Answers
The number of bacteria after 8 hours is approximately 2,713.
Let's apply the exponential growth formula:
N = N0 * e(rt),
N is the number of bacteria at a particular period. N0 is the initial bacterial population, e is the mathematical constant (about equal to 2.71828), r is the growth rate, and t is the amount of time that has passed.
The information provided in the problem can be used to determine the growth rate:
N1 = N0 * e(r*2)
N2 = N0 * e(r*4)
To get eliminate N0, divide the second equation by the first equation:
N2/N1 = e(r4) / e(r2)
385/135 = e(r4) / e(r2)
If we condense this expression, we get:
e(r*2) = 385/135
e(r*2) = 2.8519
When we take the natural logarithm of both sides, we get:
r*2 = ln(2.8519)
r = ln(2.8519)/2
r = 0.5457 (rounded to 4 decimal places)
The number of bacteria after 8 hours can now be determined using the exponential growth algorithm once more:
N = N0 * e(rt)
N = 135 * e(0.5457*8)
N = 2,713 (rounded to the nearest whole number)
Therefore, the number of bacteria after 8 hours is approximately 2,713.

What type of number is the length? List as many types of numbers for the length as you can.A=50ft^2,A=16ft^2
Answers
Explanation:
Step-by-step explanation:
a) From the image attached, the area of the small section is 16ft² and the area of the large section is 50 ft². The area of a square = length × length = length².
\(\begin{gathered} A_{big}=L^2 \\ L^2=50 \\ L=\sqrt{50}ft \\ A_{small}=l^2 \\ l^2=16 \\ l=\sqrt{16} \\ l=4ft \end{gathered}\)The length of the entire shed will be calculated using the formul below
\(length(entireshed)=length(large)+length(small)\)By substituting the values, we will have
\(\begin{gathered} length(ent\imaginaryI reshed)=length(large)+length(small) \\ length(ent\mathrm{i}reshed)=L+l \\ length(ent\mathrm{i}reshed)=4+\sqrt{50}ft \end{gathered}\)Hence,
The length of the entire shed is

The quantitative analysis also focused on finding critical statistical values like mean, median, mode, standard deviation, variance, and minimum/maximum variables. The results of the data are summarized in Table 2. Revenue Passenger Miles (RPM) mean is 6,624,897, the median is 6,522,230, and mode is NONE. The minimum is 5,208,159 and the maximum is 8,277,155. The standard deviation is 720,158.571, and the variance is 518,628,367,282.42.
Load Factors (LF) mean is 82.934, the median is 83.355, and mode is 84.56. The minimum is 74.91, and the maximum is 89.94. The standard deviation is 3.972, and the variance is 15.762. The Available Seat Miles (ASM) mean is 7,984,735, the median is 7,753,372, and mode is NONE. The minimum is 6,734,620, and the maximum is 9,424,489. The standard deviation is 744,469.8849, and the variance is 554,235,409,510.06.Figure 1 above displays the performance of American Airlines (Domestic).
The mean RPM is 7,984,735, and the linear regression line is y = 50584x - 2.53E+8. The linear regression line indicates a positive relationship between RPM and year, with a coefficient of determination, R² = 0.6806. A coefficient of determination indicates the proportion of the variance in the dependent variable that is predictable from the independent variable. Therefore, 68.06% of the variance in RPM is predictable from the year. A one-way ANOVA analysis of variance test was conducted to determine the equality of means of three groups of variables; RPM, ASM, and LF. The null hypothesis is that the means of RPM, ASM, and LF are equal.
The alternative hypothesis is that the means of RPM, ASM, and LF are not equal. The level of significance is 0.05. The ANOVA results indicate that there is a significant difference in means of RPM, ASM, and LF (F = 17335.276, p < 0.05). Furthermore, a post-hoc Tukey's test was conducted to determine which variable means differ significantly. The test indicates that RPM, ASM, and LF means differ significantly.
The skewness test was conducted to determine the symmetry of the distribution of RPM, ASM, and LF. The test indicates that the distribution of RPM, ASM, and LF is not symmetrical (Skewness > 0).
Additionally, the z-statistic test was conducted to determine the deviation of RPM, ASM, and LF from the mean. The test indicates that RPM, ASM, and LF significantly deviate from the mean.

A normal distribution (X) has a mean of 100 and a standard deviation of 10.
What is the probability that X will be smaller than 80?
Use the Normal Table and keep all 4 decimal positions in your answer.
Answers
Using the normal distribution, it is found that there is a 0.0228 = 2.28% probability that X will be smaller than 80.
Normal Probability DistributionIn a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem:
The mean is of \(\mu = 100\).The standard deviation is of \(\sigma = 10\).The probability that X will be smaller than 80 is the p-value of Z when X = 80, hence:
\(Z = \frac{X - \mu}{\sigma}\)
\(Z = \frac{80 - 100}{10}\)
\(Z = -2\)
\(Z = -2\) has a p-value of 0.0228.
0.0228 = 2.28% probability that X will be smaller than 80.

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.

Given:
Actual production and sales =n26,600 units
Actual direct labor rate = $13.00 per hour
Actual direct labor hours worked = 63,000 hours
Direct labor cost = Actual direct labor rate × Actual direct labor hours worked
Direct labor cost = $13.00/hour × 63,000 hours
Direct labor cost = $819,000

Answers
Answer:
The value of the test statistic is \(t = -1.61\)
Step-by-step explanation:
Central Limit Theorem
For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \(\mu = p\) and standard deviation \(s = \sqrt{\frac{p(1-p)}{n}}\)
Our test statistic is:
\(t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}\)
In which X is the sample mean, \(\mu\) is the expected mean, \(\sigma\) is the standard deviation and n is the size of the sample.
A publisher reports that 52% of their readers own a laptop.
This means that \(\mu = 0.52\)
Sample of 180:
Means that \(n = 180\)
By the Central Limit Theorem:
\(\frac{\sigma}{\sqrt{n}} = s = \sqrt{\frac{0.52*0.48}{180}} = 0.0372\)
A random sample of 180 found that 46% of the readers owned a laptop.
This means that \(X = 0.46\)
Find the value of the test statistic.
\(t = \frac{X - \mu}{s}\)
\(t = \frac{0.46 - 0.52}{0.0372}\)
\(t = -1.61\)
The value of the test statistic is \(t = -1.61\)
