Answer:

To determine whether a quadrilateral is a rectangle, rhombus or square, you must show that it meets the definition of that shape OR that it has properties that only that shape has.

A rectangle is a quadrilateral with four right angles. Thus, all the angles in a rectangle are equal (360°/4 = 90°). Moreover, the opposite sides of a rectangle are parallel and equal, and diagonals bisect each other.

A rhombus is a quadrilateral with all sides equal in length. The opposite angles are equal in measure. The diagonals bisect each other at right angles.

A square is a quadrilateral with all sides equal in length and all angles equal to 90 degrees4.

To determine whether ▱ABCD with vertices A(−2,3), B(2,3), C(2,−1),and D(−2,−1) is a rectangle, we can check if all angles are right angles or if the diagonals of the parallelogram are congruent.

Step-by-step explanation:

Using Binomial distribution  ( as the arrival times of workers are independent).

Formula for standard deviation: \(\sqrt{{p(1-p)}{n}}\), where p= population proportion, n= sample size.

As per given ,

p= 0.06, n=300

Required standard deviation= \(\sqrt{0.06\left(1-0.06\right)300}\)

\(=\sqrt{(0.06)(0.94)(300)}\\\\=\sqrt{16.92}\approx4.11\)

Hence, the correct option is B.

The value of x in the given polygon is 71°

A closed, flat polygon is a geometry comprised of just straight lines.

The exterior angle of a polygon is the angle created when a polygonal side is extended.

A polygon's outside angles add up to 360°.

The sum of external angles in a polygon is 360°

In the given questions all the angles, whose values are given, are external angle.

2x-46° + 2x-50° + 2x-33° + 32° + 31° = 360°

6x - 129° + 63° = 360°

6x - 66° = 360°

6x = 360° + 66°

6x = 426°

x = 426°/6

x = 71°

The value of x in the given polygon is 71°

The P-value for this hypothesis test is 0.00215

The p-value hypothesis test gives a measure of how much evidence is present to reject the null hypothesis. The smaller the p-value, the higher the evidence against the null hypothesis.

Given that:

Null Hypothesis: mu1 = mu2

Alternative Hypothesis: mu1<mu2

Notice that the alternative hypothesis is a one-tailed test

Now, when a one-tailed alternative hypothesis is used, To obtain a one-tailed alternative probability value i.e p-value, we divide the result by two (2).

so, given output ( z=3.25, p=0.0043)

since its one-tailed test:

P-value for this hypothesis test = 0.0043/2 = 0.00215

Step-by-step explanation:

The standard deviation of demand over the lead time is 23.72.

The demand over lead time is normally distributed with a mean of 80. The reorder point for a 95% service level is 119. To calculate the standard deviation of demand over the lead time, we need to use the following formula:

z = (x - μ) / σ, where z is the number of standard deviations from the mean, x is the reorder point for a 95% service level, μ is the mean of the distribution, and σ is the standard deviation of the distribution.

To solve for σ, we need to first find the z-score for a 95% service level, which can be obtained from the standard normal distribution table.

The z-score for a 95% service level is 1.645.

Substituting the given values in the formula, we get:

1.645 = (119 - 80) / σ

Solving for σ, we get:σ = (119 - 80) / 1.645

σ = 23.72

Therefore, the standard deviation of demand over the lead time is 23.72.

Answer:

Step-by-step explanation:

the answer is B

There are 15! (15 factorial) permutations with 15 inversions. This is because each inversion must correspond to a single permutation.

For example, one inversion would be switching the first two elements of the permutation, and a different inversion would be switching the last two elements. All 15! permutations can have a unique set of 15 inversions.

The number of permutations with 15 inversions can be found by using the formula for the number of inversions in a permutation. The formula is: N = (n-1)! / (n-k)!
Where N is the number of permutations with k inversions, n is the number of elements in the permutation, and k is the number of inversions.
In this case, we have n = 15 and k = 15. Plugging these values into the formula gives us:
N = (15-1)! / (15-15)!
N = 14! / 0!
N = 14! / 1
N = 87178291199
Therefore, there are 87,178,291,199 permutations with 15 inversions.

We will have that the relationship is proportional because each time he bought more sets they had the same cost, and the total cost added to the sum of the independent cost. And we have the following relationship for the 2 sets and 4 sets:

2 sets:

So, each individual set is $12.5.

4 sets:

So, each individual set is $12.5.

So, each individual set for each relationship has the same cost, therefore the relationship is proportional.

The that Reflecting a point across an axis simply involves negating the applicable  match while keeping the other Coordinate the same.The correct answer is( A)(- 5, 9).  

To reflect a point across the y- axis, we simply negate the x-coordinate while keeping the y-  match the same. thus, the reflection of the point( 5, 9) across the y- axis is(- 5, 9).  

The correct answer is( A)(- 5, 9).  Option( B)( 5,-9) represents a reflection across the x-axis, where the y-  match is negated while keeping the x-coordinate the same. Option( C)(- 5,-9) represents a point that's reflected across both the x-axis and the y- axis, performing in a point in the third quadrant.

Answer:

79°

Step-by-step explanation:

Please check the picture below.
For our ease, we label the angles as x and y

y = 180°-127° = 53°

Since, sum of three angles in a triangle is 180°,

48° + 53° + x° = 180°

x = 79°

According to the theorem of opposite angles, g° = x°

thus g° = 79°

H0: μ = 23.5 versus Ha: μ < 23.5, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam

The hypothesis is H0: μ = 25 versus Ha: μ < 25, So option (C) is the correct answer.

Mean is the ratio of the sum of all the observations and the total number of observations in a data set. The standard deviation is a statistic that measures the dispersion of a data set relative to its mean and is calculated as the square root of the variance.

For the above suituation,

There are 20 math questions to be answered in 25 minutes.

After investigation with 35 students, the meantime needed for them is 23.5 and the standard deviation is 4.8.

From the above information, we can say that the hypothesis, H0: μ = 25 versus Ha: μ < 25, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam.

Answer:

The area of the trapezoid is 108 square feet

Step-by-step explanation:

The given vertices of the trapezoid are;

(-6, 9), (-6, 6), (3, -9, and (3, 12)

Let the letters A, B, C, and D represent the vertices of the trapezoid, we have;

A(-6, 9), B(-6, 6), C(3, -9) and D(3, 12)

The drawing of the trapezoid on the coordinate plane created with MS Excel is attached

The area of a trapezoid, \(A_T\) = (a + b)×h/2

Where;

'a', and 'b' = The length of the bases (parallel sides)

h = The height of the trapezoid (The distance between the bases)

Let 'a' represent the length of the long base CD and let 'b' represent the length of the short base AB

a = √((-9 - 12)² + (3 - 3)²) = 21

∴ a = 21 feet

Similarly, we have;

b = √((9 - 6)² + (-6 - (-6))² = 3

The height, h = The distance between AB and CD = AE

We note that sides AB and CD are parallel to the y-axis, therefore, the height which is the perpendicular distance to the between AB and CD will be parallel to the x-axis

Therefore, the t-coordinates of the points A and E are both equal to 9 and the length of AE = √((3 - (-6))² + (9 - 9)²) = 9

The height of the trapezoid, AE = 9 feet

∴ The area of the trapezoid, A = (21 + 3) × 9/2 = 108

The area of the trapezoid, \(A_T\) = 108 ft.²

Step-by-step explanation:

Alex has $15.78 and Rick has $12.15 money.

According to the question,

We have the following information:

Alex had $3.63 more than Rick. Together they had $27.93.

Let's take the money Rick has to be $x.

Now, we have the following expression for the money Alex has:

3.63+x

Now, we have:

x+3.63+x = 27.93

2x+3.63 = 27.93

Subtracting 3.63 from both the sides:

2x = 27.93-3.63

2x = 24.3

Dividing by 2 on both the sides:

x = 24.3/2

x = $12.15

So, Rick has $12.15.

Now, the money Alex has:

3.63+12.15

$15.78

Hence, Alex has $15.78 and Rick has $12.15 money.
