Answer 1

Answer:

see below

Step-by-step explanation:

f(x) = 4x-3

Let x=-4

f(-4) = 4*-4 -3 = -16-3 = -19

Let x=-3

f(-3) = 4*-3 -3 = -12-3 = -15

Let x=1

f(1) = 4*1 -3 = 4-3 = 1

Let x=4

f(4) = 4*4 -3 = 16-3 = 13

Let x=5

f(5) = 4*5 -3 = 20-3 = 17

A company is approached by a new warehouse management systems vendor to adopt a new system. The vendor claims that the warehouse management system reduces the average pick, pack, and ship time to below 3 minutes per order through bin location and routing optimization. You are given an opportunity visit an existing customer of the vendor. The customer allowed you to collect data for further analysis. You performed a time study and collected data about pick, pack ship duration of 25 shipments. Given, the data in the attached excel sheet
(Q1) perform a hypothesis testing by Use alpha=0.05 for hypothesis testing.
a. Stating your null and alternate hypotheses
b. Perform the proper hypothesis test and discuss your assessment of the vendor's claim.

Answers

Answer:

The null hypothesis is [tex]H_o : \mu = 180[/tex]

The alternative hypothesis is [tex]H_a : \mu < 180[/tex]

The decision rule is fail to reject the null hypothesis

The conclusion

There no sufficient evidence to support the vendor claim that the warehouse management system reduces the average pick, pack, and ship time to below 3 minutes(180 seconds) per order through bin location and routing optimization

Step-by-step explanation:

From the question we are told that

The population mean is [tex]\mu = 3 \ minutes = 180 \ seconds [/tex]

The sample size is n = 25

The excel sheet is show on the first uploaded image

The level of significance is [tex]\alpha = 0.05[/tex]

The null hypothesis is [tex]H_o : \mu = 180[/tex]

The alternative hypothesis is [tex]H_a : \mu < 180[/tex]

Generally the sample mean is mathematically represented as

[tex]\= x = \frac{156 + 136 + \cdots + 181}{25}[/tex]

=> [tex]\= x = 173.2 [/tex]

Generally the standard deviation is mathematically represented as

[tex]\sigma = \sqrt{\frac{\sum (x_i - \= x )^2 }{n} }[/tex]

=> [tex]\sigma = \sqrt{\frac{ (156 - 173.2 )^2 + (136 - 173.2 )^2 + \cdots + (181- 173.2 )^2 }{25} }[/tex]

=> [tex]\sigma = 24.261[/tex]

Generally the test statistics is mathematically represented as

[tex]t = \frac{\= x - \mu }{\frac{\sigma}{\sqrt{n} } }[/tex]

=> [tex]t = \frac{173.2 - 180 }{\frac{24.261}{\sqrt{25} } }[/tex]

=> [tex] z = -1.40[/tex]

Generally p-value is mathematically represented as

[tex]p-value = P(Z < z)[/tex]

=> [tex]p-value = P(Z < -1.40)[/tex]

From the z-table

[tex]P(Z < -1.40) = 0.080757[/tex]

=> [tex]p-value = 0.080757 [/tex]

From the obtained value we that [tex]p-value > \alpha[/tex]

The decision rule is fail to reject the null hypothesis

B
A rotation of 90 degrees clockwise about the square's center.

C
A reflection over one of the square's sides.

D
A rotation of 180 degrees clockwise about the square's center.

E
A reflection over one of the square's diagonals.

Answers

Answer: E B D

Step-by-step explanation: I did a test

Transformation involves moving a shape from one position to another. The transformation that carries the square onto itself is:

A rotation of 90 degrees clockwise about the square's center. A rotation of 180 degrees clockwise about the square's center. A reflection over one of the square's diagonals.

For the square to carry itself onto itself, it must either be rotated or reflected.

For reflection:

It must be reflected across any of its diagonal

For rotations:

It must be rotated through its center, around multiples of 90 degrees (i.e. 90, 180, 270, 360.....)

Hence, the correct options are: B, D and E

What is midpoint of a line segment?

The midpoint of a line segment is given as,

x = (a + c)/2

y = (b + d) / 2

Where (x, y) is the midpoint and (a, b) and (c, d) are the two endpoints.

We have,

C is a point between AB.

Point C is 3/4 of the way from point A (-4,1) to point B (6,5).

This means,

AC : CB = 3 : 1 = m : n

Now,

m = 3

n = 1

(-4, 1) = (a, b)

(6, 5) = (c, d)

C = (x, y)

x = (mc + na)/(m + n)

x = (3 x 6 - 4)/4

x = (18 - 4)/4 = 14/4 = 7/2

y = (md + nb)/(m + n)

y = (15 + 1)/4 = 16/4 = 4

Now,

The coordinates of C is (7/2, 4).

Thus,

C is at the point (7/2, 4).

Answers

By answering the above question, we may state that angle with the smallest measure, the smallest-measured angle

what are angles?

An angle is a form in Euclidean geometry made composed of two rays, referred to as the angle's sides, that converge at a centre point known as the angle's vertex. In the plane where they are positioned, two rays may come together to make an angle. A planar collision produces an angle as well. Dihedral angles are what these are known as. A potential arrangement of two rays or lines that share a termination is called an angle in plane geometry. The Latin word "angulus," which means "horn," is where the English word "angle" originates. The intersection of the two rays, often referred to as the angles' sides, is known as the vertex.

Each state imposes its own excise tax on gasoline. Suppose, for example, that the state of Massachusetts imposes a state gasoline tax of $0.26 per gallon. Suppose further that an average of 1,022,000 gallons of gasoline per day were sold in Massachusetts in 2010.

Answers

Complete question :

Answer:

$265,720

Step-by-step explanation:

Given that:

State gasoline tax = $0.26 per gallon

Average number of gasoline sold per day = 1,022,000 gallons

. From the availabke information given :

Revenue generated = gasoline tax per gallon multiplied by the average number of gallons sold

= $0.26 * 1,022,000

= $265,720

The average revenue from gasoline tax in 2010 is $265,720.

Calculation of the average revenue:

Since the state of Massachusetts imposes a state gasoline tax of $0.26 per gallon. Suppose further that an average of 1,022,000 gallons of gasoline per day

So, here the average revenue should be

= 0.26 of 1,022,000

= $265,720

hence, The average revenue from gasoline tax in 2010 is $265,720.

Let triangle ABC be an isosceles triangle where angle ABC is congruent to angle BCA. Prove that the sides (AB and AC) opposite the congruent base angles of a triangle are congruent.

Answers

I constructed line AD as a perpendicular bisector of line BC. Angles BDA and CDA are both 90 degrees because of the construction of a perpendicular bisector. Angles BDA and CDA are congruent because of the transitive property of equality. Line BD is also equal to CD according to the definition of a perpendicular bisector. Triangles ABD and ACD are congruent by the angle side angle postulate. Since the parts of the congruent triangles are congruent, lines AB and AC are congruent.

The sides AB and AC opposite the congruent base angles of a triangle are congruent.

What is an isosceles triangle?

An isosceles triangle is a triangle with (at least) two equal sides. A polygon that consists of two equal sides, two equal angles, three edges, three vertices and the sum of internal angles of a triangle equal to 180°.

For the given situation,

Triangle ABC be an isosceles triangle.

∠ABC ≅ ∠BCA.

The diagram below shows an isosceles triangle ABC with AD is the perpendicular bisector of BC.

The perpendicular bisector AD divides the line BC as BD and DC.

Then, BD = DC.

We get triangles ΔADB and ΔADC,

AD = AD [∵ common side]

⇒ [tex]\angle ADB = \angle ADC=90[/tex]

Thus by ASA theorem,

The two triangles ΔADB and ΔADC are similar.

Then by CPCT theorem,

Side AB ≅ AC.

Therefore the sides AB and AC opposite the congruent base angles of a triangle are congruent.

Hence we can conclude that the sides AB and AC opposite the congruent base angles of a triangle are congruent.
