Answer:

  (a)  Figure 3

  (b)  66.2 meters per second

Step-by-step explanation:

You want to know the figure that shows the best fit of a curve to the data, and you want to know the value of the curve when x = 8 seconds.

The fit is best when the difference between the data points and the curve is minimized. Often the sum of the squared differences is the metric that is minimized when the fit is best.

The gaps between the data points and the curve shown are greatest in Figures 1 and 2, so Figure 3 has the best fit.

The speed is estimated by the equation of the curve of best fit as ...

  y = 0.6x² +2.1x +11

A slight rearrangement can make this easier to evaluate:

  y = (0.6x +2.1)x +11

For x=8, the value of y is ...

  y = (0.6·8 +2.1)·8 +11 = 6.9·8 +11 = 66.2

The predicted speed at 8 seconds is 66.2 meters per second.

The area of the shaded region in the standard normal distribution can be found to be 0.3510.

To find the area of the shaded region between -2.25 and -0.35 in a standard normal distribution, you would use a Z-table or a calculator with a built-in Z-table function.

Area between -2.25 and -0.35 = Area to the left of -0.35 - Area to the left of -2.25

Area to the left of -0.35 = 0.3632

Area to the left of -2.25 = 0.0122

find the difference between these two areas:

Area between -2.25 and -0.35 = 0.3632 - 0.0122 = 0.3510

The parallelogram ABCD's congruency can be proven using Side-Angle-Side (SAS) congruence theorem.

Prove that ΔABC ≅ ΔDCB using the Side-Angle-Side (SAS) congruence theorem.

Given that ABCD is a parallelogram, AB || CD and BC || AD. Therefore, ∠ABC ≅ ∠DCB and ∠ACB ≅ ∠DCA because they are corresponding angles.

AB ≅ CD and BC ≅ AD because opposite sides of a parallelogram are congruent.

Lastly, AC ≅ AC because it is a shared side between the two triangles.

Therefore, the following congruent parts:

∠ABC ≅ ∠DCB (by corresponding angles)

AB ≅ CD (by opposite sides)

BC ≅ AD (by opposite sides)

AC ≅ AC (shared side)

The SAS congruence theorem concludes that ΔABC ≅ ΔDCB.

Therefore , the solution of the given problem of percentage comes out to be the firm expects that each warranty it sells will be worth $1.41.

In statistics, "a%" is used to refer to a figure or number that is expressed as a percentage of 100. Additionally rare are the forms that "pct," "pct," or "pc". It is typically represented by the symbol "%," though. Additionally, there are not any indicators and the proportion of each item to the overall amount is flat. Since percentages typically add up to 100, they are essentially integers. Either the expression "fraction" or the symbol for percentage (%) .

Here,

The price to substitute each item is $200. The anticipated price for each component is thus:

Expected cost per product equals Replacement cost x Failure Probability

=> Cost per product anticipated = 0.008 x $200

=>  Expected price per item is $1.60.

So, the following is the anticipated value of each warranty sold:

Expected worth of the warranty = Failure rate x (Replacement cost - Cost of warranty)

=>   Expected guarantee value = 0.008 * ($200 - $22 - $1.60).

=>  Expected guarantee value = 0.008 * $176.40

=>  Expected warranty worth is $1.41

As a result, the firm expects that each warranty it sells will be worth $1.41.

A: y=2x+3. This is an equation for the linear relationship in slope-intercept form. The equation states that the value of y is equal to the slope of the line, 2, multiplied by the value of x, plus 3.

Slope is a measure of the steepness of a line. It is the ratio between the vertical change in a line (change in y-values) over the horizontal change in the same line (change in x-values). It is also referred to as the rate of change, as it is a measure of how quickly the value of y changes with respect to the x-value.

This equation is used to describe a straight line that has a constant rate of change between two variables. This equation can be used to determine the slope, y-intercept, and x-intercept of a line.

The slope, which is the coefficient of x in the equation (2 in this case), is the rate at which y changes with respect to x. It is the rise over run, or the change in y over the change in x. The y-intercept is the value of y when x is equal to 0 (in this case, it is 3). The x-intercept is the value of x when y is equal to 0 (in this case, it is -3/2).

This equation is often used to represent a linear relationship between two variables, such as the amount of money a person earns in relation to the number of hours they work.

Because this problem is not easily solvable through factoring, we must use long division to find the answer.

      _______________                                                                                  x+7 | x3 + kx2 - 34x + 56

When performing long division on polynomials, we should try to cancel out the term with the greatest power first. So, we must figure out how many x's go into x3, because x is the first term of the first polynomial and x3 is the first term of the second polynomial. x*x2 = x3, so:

     x2

      _______________                                                                                  x+7 | x3 + kx2 - 34x + 56

  (-)  x3 + 14x2

         (k-14)x2 - 34x

Then, we see how many x's go into (k-14)x2. x*(k-14)x = (k-14)x2, so:

     x2 + (k-14)x

      _______________                                                                                  x+7 | x3 + kx2 - 34x + 56

  (-)  x3 + 14x2

         (k-14)x2          - 34x

    (-)  (k-14)x2 - 7kx - 98x

                        -7kx - 132x + 56= (-7k-132)x + 56

x*(-7k-132) = (-7k-132)x, so:

     x2 + (k-14)x + (-7k-132)

      _______________                                                                                  x+7 | x3 + kx2 - 34x + 56

  (-)  x3 + 14x2

         (k-14)x2          - 34x

    (-)  (k-14)x2 - 7kx - 98x

                        (-7k-132)x          + 56

                    (-) (-7k-132)x - 7k - 924

                                          -7k - 868

The answer is x2 + (k-14)x + (-7k-132) - [(7k-868)/(x+7)]

Using the right cone formula we know that the surface area is 1281.77638m³ respectively.

An axis that is perpendicular to the base plane defines a right circular cone. By rotating a right triangle around one of its legs, we may create a right cone.

The right circular cone in the illustration has an axis that is perpendicular to the base and a circular base with a radius r.

So, the formula for the surface area of the right cone is as follows:

πr(r+√h²+r²)

We have the values: r = 13m and h = 13m

Now, insert values as follows:

= πr(r+√h²+r²)

= π13(r+√13²+13²)

= 1281.77638

Answer:

To solve the problem, we can draw a number line and mark off the distances that Amiya jogged.

We start at 0 and mark off 1/3 of a mile to represent the distance Amiya jogged initially. Then we mark off another 1/3 of a mile to represent the distance she jogged after resting.

The total distance Amiya jogged is the distance from the starting point (0) to the end point (2/3), which is 2/3 of a mile.

Therefore, Amiya jogged a total of 2/3 of a mile.

Taking it further, to convert miles to meters, we need to know that 1 mile is equal to 1609.34 meters (approximately).

So to find out what 2/3 of a mile is in meters, we can multiply 2/3 by the conversion factor:

2/3 mile x 1609.34 meters/mile = 1072.89 meters

Therefore, 2/3 of a mile is approximately equal to 1072.89 meters.

Check the attached image for labeling. Since each number is the product of the two numbers directly beneath it. We can say:

m = -4 * 0.5 = -2

k = 0.5 * 1/8 = 1/16

x * (-1/8) = 8

x = 8/(-1/8)

x = -64  

y = x * 1/8

y = -64 * 1/8

y = -8

j = m * k

j =  -2 * 1/16 = -1/8

p = -48 * m

p = -48 * (-2) = 96

n = y * 8

n = -8 * 8 = -64

t = p * j

t = 96 * (-1/8) = -12

w = -1/2 * n

w = -1/2 * (-64) = 32

c = t * 1/16

c = -12 * 1/16 = -3/4

The mean is a measure of central tendency that represents the average value of a set of numbers. It is also called the arithmetic mean or simply the average.

We cannot make a general assumption about whether the mean is greater or less than 3.5 based solely on the fact that the median is 3.5.

The mean and the median are two different measures of central tendency, and they can have different values depending on the distribution of the data. In general, if a data set is symmetric and bell-shaped, the mean and the median are close to each other. However, if the data set is skewed, the mean and the median may be different.

For example, consider the following two data sets:

Set 1 data: 1, 2, 3, 4, and 5.

The median is 3.

The mean is (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3.

Data set 2: 1, 2, 3, 4, 10

The median is 3.

The mean is (1 + 2 + 3 + 4 + 10) / 5 = 20 / 5 = 4.

In data set 1, the mean is the same as the median. In data set 2, the mean is greater than the median because the value 10 is an outlier that pulls the mean up.

Additional comment

You can figure the hypotenuse using the Pythagorean theorem if you haven't memorized the side relations of this "special" right triangle.

  c² = 7² + b²

  c² = 7² +7² = 2·7²

  c = √(2·7²) = 7√2
