The measure of central tendency best suited for the given situation are mode (a), median (b) and mean (c) respectively.

a. The measure of central tendency best suited for this situation is the mode, because it would provide the most representative score of the favorite season. The mode is the most commonly occurring value in a set of data, so it would be useful for determining the most popular season among the sample of 50 adults.

b. The measure of central tendency best suited for this situation is the median, because it would provide the most representative score of the length of stay in the hospital after a routine appendectomy. The median is the middle value in a set of data when the values are arranged in numerical order, and it is not affected by very high or very low values (as the mean is). Therefore, it would be the most useful for determining the average length of stay in the hospital for this particular sample.

c. The measure of central tendency best suited for this situation is the mean, because it would provide the most representative score of the standardized reading test scores. The mean is the average of all the values in a data set, so it would be useful for determining the average score of the sample of children from the middle-class, suburban elementary school.

One possible transformation is a Rotation, followed by a Translation.

There are rigid and non-rigid transformations (where the preimage's size or shape is left unaltered) (where the size is changed but the shape remains the same). These are the fundamental principles that this idea abides by. It is a simple method for transforming 2D shapes.

By separating between planar transformations and spaces, the transformation can be grouped according to the dimensions of the operand sets. They can be categorised based on their characteristics as well.

An object's image will resemble its pre-image when its size is changed, whether for larger or smaller objects. Dimensions are proportionally equal for the similar figures.

The amount of silk used in one minute by the factory was 126

An equation is an expression showing the relationship between two or more numbers and variables. An equation can either be linear, quadratic, cubic and so on depending on the degree.

A factory makes 3.5 silk flowers every second.

60 second = 1 minute

Amount of silk made in one minute = 3.5 silk flowers every second * 60 seconds = 210 silk flowers

Each flower uses 60.3 cm of silk.

Hence, for 210 silk flowers:

Amount of silk used = 210 silk flowers * 60 cm of silk = 12600 cm of silk

100 cm = 1 m

12600 cm =  12600 cm * 1 m per 100 cm = 126 m

The amount of silk used was 126

The Pythagorean Theorem states that for a right triangle, the length of the hypotenuse squared is equals to the sum of the squared lengths of the sides of the triangle.

For this problem, we have that:

Applying the Pythagorean Theorem, the value of c is obtained as follows:

Answer: l = (2x-3) ; b = (2x-10) ; Perimeter = (10x - 26)

Step-by-step explanation:

l * b = area

area = 6x^2 - 29x + 30

l * b = 6x^2 - 29x + 30

Split the middle term of 6x^2 - 29x + 30

6x^2 - 20x - 9x + 30

2x(3x-10) -3(3x-10)

(2x-3) (3x-10)

l = (2x-3)

b = (3x-10)

Perimeter of a Rectangle = 2(l+b)

= 2 ((2x-3) + (3x-10))

= 2( 2x-3 + 3x-10 )

= 2 (5x -13)

= (10x - 26)cm

Step-by-step explanation:

The definite integral of the function (2x - 3) with respect to x can be found using the antiderivative, also known as indefinite integration.

The antiderivative of (2x - 3) is:x^2 - 3x + C, where C is the constant of integration.

For the definite integral, we need to find the antiderivative over a given interval. To calculate the definite integral, we need to evaluate the antiderivative at the limits of the interval and subtract the values.So, for example, if the interval is from a to b, the definite integral is given by:∫_a^b (2x - 3) dx = (x^2 - 3x) |_a^b = (x^2 - 3x) evaluated at b - (x^2 - 3x) evaluated at a.The definite integral of the function y³ (2y² – 3) with respect to y can be found in a similar way. The antiderivative of y³ (2y² – 3) can be found using power rule of integration.The antiderivative of y³ (2y² – 3) is:(1/4) y⁴ - 3y² + C, where C is the constant of integration.The definite integral of the function can then be found by evaluating the antiderivative at the limits of the interval and subtracting the values, as described above.

The system of equations is:

-2x + 3y = 15

x + y = 10

We can use elimination to solve this system. One way to eliminate x is to multiply the first equation by -2 and add it to the second equation:

(-2) * (-2x + 3y = 15) + (x + y = 10)

4x - 6y + x + y = 15 + 10

5x - 6y = 25

5x = 25 + 6y

x = 5 + (6/5)y

Substituting x back into the second equation, we get:

x + y = 10

5 + (6/5)y + y = 10

Combining like terms:

y = 10 - 5 - (6/5)y

(11/5)y = 15 - 5

(11/5)y = 10

y = 10 * (5/11)

y = 10/11

Finally, substituting x = 5 + (6/5)y back into the equation we found earlier:

x = 5 + (6/5)y

x = 5 + (6/5) * (10/11)

x = 5 + (60/55)

x = 55/11 + 60/55

Combining like terms:

x = (55 + 60) / 55

x = 115/55

The solution to the system of equations is (x, y) = (115/55, 10/11).

So the answer is (d) (9, 11).

yes ,it is easier to get a precise estimate of the binomial parameter when π is near 0 or 1 than when it is near 1/2

in binomial distributions, we have parameters for the probability of success or failure (either of the two conditions that the variable may take), and for the number of trials, which turn out to be easier to estimate for extreme values.

Due to the estimator's decreasing standard error, it is simpler to estimate a binomial parameter when it is closer to 0 or 1 than when it is 0.50. Since the latter has p(1 - p) in its numerator, a value close to 0 or 1 reduces the standard error to almost zero. It is simpler to estimate a binomial parameter correctly when the standard error of the estimate is exceptionally low. It is more challenging to estimate when the parameter is 0.50, which reflects the highest amount of inaccuracy. As either event is equally likely, a value of 0.50 can be thought of as introducing greater ambiguity. When it's far away from 1 or 0, it appears to be much more likely that one of the answers is correct.

The member of the art club are making keychain that require 18 bead apiece and the art club adviser brought a bag with 250 bead for them to use, if there are 70 bead left in the end, then 5 keychain were made.

The member of the art club are making keychain that require 18 bead apiece.

The art club adviser brought a bag with 250 bead for them to use.

Let the member of the art club are make x keychain.

So the number of beads used in making x keychains = 18x

The left beads are 70.

So the total beads = 18x + 70

But they have total 250 beads.

So the equation should be:

18x + 70 = 150

Subtract 70 on both side, we get

18x = 80

Divide by 18 on both side, we get

x = 5

Rounding to the nearest tenth of a foot, the ramp length is 150.7 feet.

To find the length of the ramp, we can use the Pythagorean theorem, which states that in a right triangle, the square of the length of the hypotenuse (the ramp) is equal to the sum of the squares of the other two sides (the rise and the run).

We have the rise (15 feet) and the run (150 feet), so we can use the formula: ramp length = √(rise^2 + run^2)

Plugging in the values, we have: ramp length = √(15^2 + 150^2) = √(225 + 22500) = √22725 = 150.7 feet

Therefore, rounding to the nearest tenth of a foot, the ramp length is 150.7 feet.

A unit circle has a radius of 1, so r = 1. The point P(9/10, y) in the IV quadrant will have a positive x-value and a negative y-value.

Using the Pythagorean theorem we know that, x² + y² = r², in a Cartesian coordinate system. We can solve for y by rearranging the formula, r² - x2 = y², or y = ±√(r² - x²).

y = ±√(r² - x²)

y = ±√([1]² - [9/10]²)

Simplify the expression we have

y = ±√(1 - 81/100)

y = ±√(1-0.81)

y = ±√0.19, we choose the negative for quadrant IV.

y = -√0.19

y = -0.4359

To calculate the speed of the car, you can use the following formula:

Speed = \frac{Distance}{Time}

In this case, the speed of the car is:

Speed = \frac{44 ft}{0.5 s} = 88 ft/s

To convert from feet per second to miles per hour, you can use the following formula:

Miles per hour = \frac{Feet per second}{1.467}

Therefore, the speed of the car is:

Miles per hour = \frac{88 ft/s}{1.467} = 59.89 mph
