Answer:

B and D.

Step-by-step explanation:

B  This is a fair method. There is an equal chance  for all 3 people because picking one of the three is random.

D. I can't see all of it  but it looks like it will be  ' if the number is 5 or 6 Elena will bathe the dog. This is fair because the probabilities are all 1/3.

Method D is a fair method because the probability of each is equal.

Determining the proper option, acquiring evidence, and exploring various options are all steps in the decision-making process.

Ana, Mateo, and Elena are arguing about who has to give the dog a bath.

Then a fair decision will be

A. Roll a number cube. If the number rolled is 2 or 4, Ana bathes the dog. If the number is odd, Elena bathes the dog. If it lands on any other number, Mateo bathes the dog.

This is not a fair method because the probability of each is not equal.

B. Put each person's name on a separate piece of paper in a bag Randomly draw a name. The person whose name is chosen bathes the dog.

This is not a fair method because the number of pieces of paper is not given.

C. Flip a coin twice. If both tosses are heads, Ana bathes the dog. If one is headed and one is tail, Mateo bathes the dog. If both are tails, Elena bathes the dog.

This is not a fair method because the probability of each is not equal.

D. Roll a number cube. If the number rolled is 1 or 2, Ana bathes the dog. If the number is 3 or 4, Mateo bathes the dog. If the number​ rolled is 5 or 6, Elena bathes the dog.

This is a fair method because the probability of each is equal.

Then the correct option is D.

Answer:

  f(x) = -2|x-2| +4

Step-by-step explanation:

Step 1: recognize this as an inverted, scaled, and translated absolute value function.

Step 2: identify the scale factor as 2, because each section has a "rise" of 2 for each "run" of 1. The scale factor is -2 because the function is inverted (reflected across the x-axis).

Step 3: identify the vertex* as (2, 4).

Step 4: Use the scale factor and translation information to make the transformation ...   (let abs(x) represent the absolute value function)

  f(x) = (scale factor)×abs(x -horizontal shift) + (vertical shift)

  f(x) = -2|x -2| +4

_____

* The vertex is an identifiable point on the graph of this function. Knowing how the vertex is translated tells you how the whole function is translated. In general, you want to use an identifiable point (a turning point, point of symmetry, extreme point, whatever) when you're trying to determine the translation. For some functions, like a line, there is no specific identifiable point, so determining any specific translation is difficult or impossible.

Step-by-step explanation:

Given:

Position of car = s(t) = 60t-1.5t^2

The speed is the change in position.

  165 + 40w = 500 +0.10×500

  40w = 385 . . . . . subtract 165 and simplify

Answer:

0.000052

1 nanometer = .000000001 meters

.000000001 x 52000 = 0.000052

To convert 52,000 nanometers to meters, divide by the conversion factor of 1,000,000,000 nanometers per meter, resulting in a thickness of 5.2 x 10-8 meters in standard form.

To convert the thickness of a piece of thread from nanometers to meters, we need to use the conversion factor that 1 meter equals 1,000,000,000 nanometers, or 1 m = 109 nm.

Using this conversion factor, we can set up the following calculation:

Thickness in meters = Thickness in nanometers \/ Conversion factor

Thickness in meters = 52,000 nm \/ (109 nm/m)

Thickness in meters = 52,000 nm \/ 1,000,000,000 nm/m

Thickness in meters = 0.000000052 m or 5.2 x 10-8 meters when expressed in standard form.

The best predicted value of y for x = 5 is 27.

A regression equation is a mathematical model that represents the relationship between a dependent variable and one or more independent variables. It expresses the linear or nonlinear association between these variables and is derived from statistical methods like linear regression analysis.

To predict the value of y for x = 5 using the regression equation, you can substitute x = 5 into the equation y = 5x + 2:

y = 5(5) + 2 = 27

Therefore, the predicted value of y for x = 5 is 27.

The best predicted value of [tex]\( y \) for \( x = 5 \) is \( y = 27 \).[/tex]

To find the best predicted value of [tex]\( y \) for \( x = 5 \),[/tex]we substitute [tex]\( x = 5 \)[/tex] into the regression equation:

[tex]\[ y = 5x + 2 \] \[ y = 5(5) + 2 \] \[ y = 25 + 2 \] \[ y = 27 \][/tex]

To reconcile this discrepancy, if we assume that the provided value of [tex]\( y = 18.3 \)[/tex] corresponds to [tex]\( x = 5 \),[/tex] then we would set the regression equation equal to 18.3 and solve for \( x \):

[tex]\[ 18.3 = 5x + 2 \] \[ 16.3 = 5x \] \[ x = \frac{16.3}{5} \] \[ x = 3.26 \][/tex]

Observational study.

------APEX

Answer:

Step-by-step explanation:

The choices for this question are

a. Double-blind study

b. Experiment

c. Sample survey

d. Observational study

The right answer would be d. Observational study, because this type of study is defined as an empirical and non-experimental research where all information is obtained by observation. When we apply this study, we try to find a cause-effect relation by observing the phenomenon as it naturally happens, that is, without interfering with the course of events like experimental investigations do.

So, in this case, Matilda is just observing, without altering anything that could influence the birds. She just sits observe and recover information, that's an observational study.

Therefore, the right answer is d.

Step-by-step explanation:

The easiest segment to work with is BC, since the y-values are the same for coordinates B and C and for B' and C'.

The length of BC = 9 -(-9) = 18.

The length of B'C' = 7 -(-1) = 8.

The scale factor is B'C'/BC = 8/18 = 4/9.

Answer:

  D)  33

Step-by-step explanation:

The sum of the lengths of the segments is equal to the overall length:

  (3x -5) + 8 = 4x -7

  10 = x . . . . . . . . . . . . add 7-3x to both sides

Then the overall length is ...

  MO = 4·10 -7 = 33

Answer:

The zeros of the polynomial function f(x) = x^3 + x^2 + 20x are 0, -5, -4.

The zeros of a polynomial function are the values of x that make the function equal to zero.

We are given that one zero of the polynomial function f(x) = x^3 + x^2 + 20x is x = 0.

To find the other zeros, we can use polynomial long division or synthetic division to factor out x = 0 and find the remaining quadratic equation.

Factoring the quadratic equation, we find that the zeros are x = -5 and x = -4.

Therefore, the correct answer is 0, -5, -4.

Final answer:

The zeros of the polynomial function f(x) = x^3 + x^2 + 20x are 0, -5, and -4.

Explanation:

The zeros of a polynomial function are the values of x that make the function equal to zero. Given that one zero of the polynomial function f(x) = x^3 + x^2 + 20x is x = 0, we need to find the other zeros. To do this, we factor the polynomial using synthetic division or long division. In this case, the factored form of the polynomial is f(x) = (x)(x + 5)(x + 4). Therefore, the zeros of the polynomial function are 0, -5, and -4.

  f(x) = -2.5

You can leave the equation like this, or write it as ...

Answer:

  see below

Step-by-step explanation:

The formula for the sum of an infinite geometric series with first term a1 and common ratio r (where |r| < 1) is ...

  sum = a1/(1 -r)

Applying this to the given series, we get ...

a. sum = 5/(1 -3/4) = 5/(1/4) = 20

b. sum = d/(1 -1/t) = d/((t-1)/t) = dt/(t-1)

_____

The derivation of the above formula is in most texts on sequences and series. In general, you write an expression for the difference of the sum (S) and the product r·S. You find all terms of the series cancel except the first and last, and the last goes to zero in the limit, because r^∞ → 0 for |r| < 1. Hence you get ...

  S -rS = a1

  S = a1/(1 -r)

Find the perimeter of the yard ( the distance around the yard).

A rectangle has two sides of each dimension.

The perimeter is 20 + 20 + 45 + 45 = 130 feet.

Now multiply the total feet by the cost per foot:

130 feet x 25 per foot = $3,250 total.

Danny needs to spend on his yard $3250 to fencing.

The rectangle is a geometrical figure in which opposite sides are equal.

The angle between any two consecutive sides will be 90 degrees.

Area of rectangle = length × width.

Perimeter of rectangle = 2( length + width).

Length of fence = Perimeter of his yard(rectangle)

Perimeter of rectangle = 2( length + width).

Perimeter of fence =2 ( 20 + 45 )

The perimeter of fence =130 foot.

Now

Cost = $25 per foot

So,

Cost of 130 feet at the rate of  $25 per foot

⇒ 130 × 25 = $3250

Hence, Danny needs to spend on his yard $3250 to fencing.
