Answers

Answer 1

The margin error is the amount that is added to and subtracted from a point estimate in order to create a confidence range for the population parameter.

The margin error, or error rate, in statistics refers to how inaccurate survey results utilizing random samples are. A larger statistical margin of error indicates a decreased likelihood of relying on a survey's or poll's results, indicating a decreased level of trust in the results' capacity to fairly represent a community. It is an essential tool for market research since it demonstrates the level of trust that should be placed by the researchers in survey results.

Is it a zero if it touches the x-axis?.

Answers

At the zero point the curve can either cross the x-axis or just touch it. The root of the function is the number c with f(c) = 0.

If the graph intersects the x-axis and looks nearly linear at the intersection, it is a single root. Even multiplicity zero if the graph touches the x-axis and bounces off the axis.

Different graphs with different x-intercepts. The graph may intersect the x-axis at the intersection. Otherwise, the graph touches the x-axis and bounces.

For example, suppose you plot a function.

f (x) = (x + 1) (x - 2)²

See the figure above to see how the function behaves differently for different x intercepts.

x intercept at x = -1 is the solution of the equation

x + 1 = 0 , graph goes straight through the x intercept at x= −1 . We call it a single zero because zero corresponds to a single factor in the function.

x intercept at x = 2 is the iterative solution of the equation ( x - 2 )= 0

The graph touches the axis at the intercept and changes direction. The coefficients are quadratic (order 2), so, (x-2)²= (x - 2 )(x - 2)

coefficients are repeated and appears twice. The number of times a given factor appears in the factored form of a polynomial equation is called its multiplicity. Zero associated with this factor, the factor is (x-2), occurs twice, and has a multiplicity of 2 .

thus, the behaviour of graph shows that any point of f(x) which touch or intersect x-axis is call zero of f(x).

b. in the below figure, the system has been balanced using lean techniques to meet the takt time as much as possible and the facility works 1 shift of 8 hours with two 15 min breaks, what is the daily demand?

Answers

The system has been balanced using lean techniques to meet the takt time as much as possible and the facility works 1 shift of 8 hours with two 15 min breaks, so the daily demand is 2700 units / day.

In the given question, the system has been balanced using lean techniques to meet the takt time as much as possible and the facility works 1 shift of 8 hours with two 15 min breaks.

We have to find the daily demand.

The figure is given below:

Total operating time of the facility = 8 hours - 2 breaks of 15mins each

Total operating time of the facility = 480 mins - (2*15 mins)

Total operating time of the facility = 480 mins - 30 mins

Total operating time of the facility = 450 minutes.

Time taken for 1 output = Cycle time of system = Bottleneck of the supply-demand matched process = 10 seconds.

Total output = Total operating time / Time taken for 1 output

Total output = 450 minutes / 10 seconds

Total output = 2700 units / shift.

Since the market's demand and operational time are in balance, all production is created using the pull principle.

That means; Supply = demand.

Therefore the market demand for the product = 2700 units / day.

What other pair of corresponding congruent parts is needed to prove that the two triangles are congruent by ASA congruence postulate?.

Answers

Two triangles if the side between any two corners of one triangle cornor corresponds to the side between the corresponding two angles of the second triangle corner are said to be congruent by the ASA rule.

Create a point F' on ray AC such that BF' is equal to DE.

Angle BAF' = angle BAC, which equal to

angle EDF, AB = DE (given), so ∆ DEF

= ∆ ABP

Point F' has two possibilities: F' is equal to point C please.

If F' is not on C, line AC and ray BC intersect only at C, so F' is not on ray BC. Therefore the angle ABF' is not = the angle ABC. But this is a contradiction. Because angle ABF' = angle DEF (because ∆ DEF = ∆ ABF') and angle DEF = angle ABC (given). So, this case does not occur.

Therefore, F' = C must be true.

∆ABC = ∆ABF' = ∆DEF.

The reasonwe only need some parts to

c) 12.3x – 8 = 3(–6 + 4.1x)

What is  Linear equations?

A linear equation is an equation within which the very best power of the variable is usually one.

Main body:

A linear equation can be said to have an infinite number of solutions when the number of the right hand side is the same at the number on the left hand side of the equation.

For example:

2 = 2 or x = x or 0 = 0

Solving the question above:

Which linear equations have an infinite number of solutions? Check all that apply.

a) (x – 3\7) = 2\3 (3\2x – 9\14 )

x - 3/7 = 6x/6 - 18/42

x - 3/7 = x - 3/7

Collect like terms

x - x = -3/7 + 3/7

0 = 0

The linear equation in option a has an infinite number of solutions

b) 8(x + 2) = 5x – 14

8x + 16 = 5x - 14

Write an equation of a line in lope-intercept for that i perpendicular to the line y=1/2x-5 and pae through the point (1, -2)

Answers

Step-by-step explanation:

the slope-intercept form is

y = ax + b

"a" being the slope, "b" being the y-intercept (the y-value when x = 0).

to find the slope of the target line we use the slope of the given line : 1/2.

remember, the slope is expressed as ratio (y coordinate change / x coordinate change).

the given line increases the y- value by 1, when the x-value increases by 2.

a perpendicular slope (90°) simply turns y and x upside-down and flips the sign.

so, 1/2 turns into -2/1 = -2.

so, we see our line equation looks like

y = -2x + b

to get b we use the coordinates of the given point :

-2 = -2×1 + b

-2 = -2 + b

0 = b

so thar equation is simply

y = -2x

p-hat = 0.02029286

b) Now, more than 30% do not have own credit card.

P(p-hat>0.3) = P((phat- p)/sqrt(p×(1-p)/n) >(0.3-0.29)/sqrt(0.29× (1-0.29)/500))

=P(Z>0.49) =0.3121 (from standard normal table)

c) Sample size (n) = 500 and p-hat lies between 25% to 30% .

at one school, the average amount of time that tenth-graders spend watching television each week is 20.8 hours. the principal introduces a campaign to encourage the students to watch less television. one year later, the principal wants to perform a hypothesis test to determine whether the average amount of time spent watching television per week has decreased from the previous mean of 20.8 hour

Answers

the average amount of time spent watching television per week has decreased from the previous mean of 20.8 hour then the test is left tailed

In two tailed hypothesis, the alternative hypothesis is when mean can either be lesser or greater than the given value. Usually uses the symbol ≠.

In right tailed, the alternative hypothesis is when the mean is greater than the given value.

In left tailed, the alternative hypothesis is when the mean is lesser than the given value.

In this question, the hypothesis test to be performed is to determine if the average amount of time spent watching television per week has decreased from the given value of 20.8 hours.

Thus, it is left tailed test.

Why is partitioning a directed line segment into a ratio of 1/2 is not the same as finding half the length of the directed line segment?.

Answers

The difference between partitioning into a ratio of 1/2 and finding half of a line segment is that partitioning in that ratio means one part is longer than the other, whereas finding half the length means both parts are the same length.

What is the partition of the line?

Partition means to separate or to divide. A line segment can be partitioned into smaller segments which are compared as ratios.

When we say we want to partition a line into a ratio of say x/y, it means that the line has been divided in that ratio and as such, the total number of parts is x + y.

Similarly, when we partition a line in the ratio 1/2, it implies that the total number of parts of the line segment is 1 + 2 = 3.

This means one part of the divided segment is bigger than the other one.

In contrast, half of the line segment means that the line segment is divided into two equal parts.

Thus, the fundamental difference between partitioning into a ratio of 1/2 and finding half of the line segment is that partitioning in that ratio means one part is longer than the other while half the length means that both parts are the same length.

Because 1:2 is not a fraction while 1/2 is, you cannot assume that 1:2 is one-half of a line or anything that is being delt with in fact. The length of the line might be 18 units, and if it says that there needs to be some sort of action with a ratio of 1:2, you are not splitting that length in half, you are taking one unit from the left side, and two from the right, which does not equal the length of half of 18 units.

here is a hanger that is in balance. squares are worth 2 grams and circles are worth 3 grams, and triangles are x grams. write an equation to represent the hanger diagram.

Answers

The equation to represent the hanger diagram is   5x - 2x = 21 - 12 and weight of 1 triangle in the hanger is 3 gram. .

In the question ,

it is given that ,

the the weight of one square is = 2 gram

the weight of one circle is = 3 gram

and the weight of one triangle is is = x gram

When the hanger is balanced , then weight on Left side =  weight on Right side

we see that left side have 2 triangles , 6 squares and 3 circles ,

and the Right side have 2 circle , 3 square and 5 triangle ,

So , the balanced equation for the hanger can be written as

2*x + 6*2 + 3*3 = 2*3 + 3*2 + 5*x

2x + 12 + 9 = 6 + 6 + 5x

2x + 21 = 12 + 5x

5x - 2x = 21 - 12

3x = 9

x = 3

Therefore , the equation is 5x - 2x = 21 - 12  and the weight of triangle is 3 grams .

The given question is incomplete , the complete question is

There is a hanger that is in balance. squares are worth 2 grams and circles are worth 3 grams, and triangles are x grams. write an equation to represent the hanger diagram and find the weight of 1 triangle .
