Answer:

D)The height of the red prism is three times the height of the blue prism

Step-by-step explanation:

Here is the complete question

Two rectangular prisms have the same volume. The area of the base of the blue prism is 2 1/6 square units. The area of the base of the red prism is one third that of the blue prism.

which statement is true?

a)The height of the red prism is one-third the height of the blue prism

B)The height of the red prism is the same as the height of the blue prism

C)The height of the red prism is six times the height of the blue prism.

D)The height of the red prism is three times the height of the blue prism

Solution

Since both prisms have the same volume, V = A₁h₁ = A₂h₂ where A₁ and A₂ are the areas of the red and blue prisms respectively and h₁ and h₂ are the heights of the red and blue prisms respectively. For the question, A₁ = A₂/3. Substituting this into the equation, A₁h₁ = A₂h₂

A₂h₁/3 = A₂h₂

h₁ = 3h₂ . So the height of the red prism is thee times the height of the blue prism.

There has been a statistically significant change in the mean length of the candy bars since the computed t value, -2.913, is less than the critical t value of -2.718. Therefore, we reject the null hypothesis that the mean length has not changed.

A hypothesis test is performed to test the claim at the 0.02 level that there has been no change in the mean length of candy bars. The null hypothesis is that the mean length remains 43mm, as given. The alternate hypothesis is that the mean length has changed. A sample of twelve bars is taken and with the given data, the computed t value is -2.913.

For a two-tailed test at the 0.02 significance level and degrees of freedom (n-1) equals 11, the critical t values are -2.718 and 2.718. If the computed t value falls beyond this range, that is, below -2.718 or above 2.718, we reject the null hypothesis. In this case, -2.913 is less than -2.718

Therefore, there has been a statistically significant change in the mean length of the bars as the t value lies in the rejection region.

The correct option is Yes, because the computed t lies in the rejection region. The t-test analysis indicates a statistically significant change in the mean length of candy bars based on the computed t-value falling in the rejection region.

Null Hypothesis (H0): The mean length of the candy bars is 43 mm.

Alternate Hypothesis (Ha): There has been a change in the mean length of the candy bars.

T-Test Analysis: The computed t-value of -2.913 falls in the rejection region, indicating statistical significance, therefore rejecting the null hypothesis. Hence, there has been a statistically significant change in the mean length of the bars.

Answer:

The slope is 2

Step-by-step explanation:

Slope = [tex]\frac{rise(changeiny)}{run(changeinx)} =\frac{y2-y1}{x2-x1} =\frac{12-4}{6-2} =\frac{8}{4}[/tex]

8/4 reduces to 2/1 which makes the slope 2

The slope of the line is m = 2.

     To find the slope through two points, you need to apply the following formula:

[tex]\sf m=\cfrac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the values:

[tex]\sf m=\cfrac{12-4}{6-2}[/tex]

Answer: All of the answers are correct.

Step-by-step explanation:

A probability distribution is the collection of probabilities which defines the likelihood of observing all the various outcomes of an experiment or event. A probability distribution has two main properties which are that:

• Each probability in the distribution consist of a value between 0 and 1.

• The sum of all probabilities in the distribution equals 1.

Also, in probability, an outcome is the possible result of an experiment and each possible outcome gotten is unique, therefore the different outcomes are mutually exclusive i.e. only one outcome can occur on each trial during the experiment.

The sum of all probabilities of possible outcomes in a probability distribution must equal 1.0, and the probability of each outcome must be between 0.0 and 1.0, inclusive.

A probability distribution is a function that assigns probabilities to all possible outcomes of an experiment. The correct statement about a probability distribution is that the sum of all probabilities of possible outcomes must equal 1.0. This is known as the axiom of probability. In addition, the probabilities of each outcome must be between 0.0 and 1.0, inclusive. This ensures that probabilities are valid and within the appropriate range. The outcomes themselves do not have to be mutually exclusive; they can overlap or have common elements.

Answer:

The value of x is 5.

Step-by-step explanation:

We are given the following in the question:

Area of rectangle = 70 square miles

The sides of the rectangle are:

[tex]w = x, l = (2x+4)[/tex]

Area of rectangle =

[tex]A = l\times w[/tex]

Putting values, we get.

[tex]70 = (2x+4)x\\\Rightarrow 2x^2 + 4x - 70 = 0 \\\Rightarrow 2(x + 7)(x - 5) = 0\\\Rightarrow (x+7) = 0, (x-5) = 0\\\Rightarrow x = -7, x = 5[/tex]

Since, the value of x cannot be negative as it represents side of a rectangle.

Thus, the value of x is 5.

Answer:

x = 55 degrees.

y = 49 degrees.

Step-by-step explanation:

AB =  AD and BC = DC so we have 2 isosceles triangles here thus the base angles are equal.

Therefore  m < y = (180 - 82)/2 = 98/2

= 49 degrees.

m < x = (180 - 2*35)/2 = 55 degrees.

Answer:

A. f(x) increases by 3.5%

Step-by-step explanation:

Given:

City of Thomasville.

Population in 2006, [tex]P_o[/tex] = 2460

Exponential function, f(x) = 2460(1.035) ^x    ...equivalent to [tex]P=P_o(1+r)^t[/tex]

Function change at x = 2, 3

According to the question:

Plugging the values of x= 2 and x=3 we have to find the population at different x.

So,

At x= 2                                      At x=3

⇒ [tex]P_2=P_o(1+r)^t[/tex]                        ⇒ [tex]P_3=P_o(1+r)^t[/tex]

⇒ [tex]P_2=2460(1.035)^x[/tex]                     ⇒ [tex]P_3=2460(1.035)^x[/tex]

⇒ [tex]P_2=2460(1.035)^2[/tex]                     ⇒ [tex]P_3=2460(1.035)^3[/tex]

⇒ [tex]P_2=2622.4[/tex]                               ⇒ [tex]P_3=2707.7[/tex]

Percent change :

⇒ [tex]\triangle \% =\frac{Final\ value -Initial\ value}{Initial\ value} \times 100[/tex]

⇒ [tex]\triangle \% = \frac{(P_3-P_2)}{P_2} \times 100[/tex]

⇒ [tex]\triangle \% = \frac{(2707.7-2622.4)}{2622.4} \times 100[/tex]

⇒ [tex]\triangle \% = 3.5[/tex]

So,

The function f(x) increases by 3.5% option A is the right choice.

The center of the plot is at $36 rather than $37

Center = $ 36

Step-by-step explanation:

The description by Margot is accurate except for the following observation

From the dot plot there are 31 dots, therefore, the center should be at the median mark of the dot plot of the graph which is the 16th dot.

By looking at the dot plot it is observed that both 16th dot and the middle of the cluster are located on the $37.

That is the point where Margot make an error is defining the center as $37, where the center is observed to be $36.

Answer:

Not enough statistical evidence to prove that treatment 2 sample mean u2 is less than treatment 1 sample mean u1. So the claim may be supported.

Step-by-step explanation:

Solution:-

- The sample size of two treatments, n = 16

- The mean of sample treatment 1, u1

- The mean of sample treatment 2 , u2

- The significance level, α = .05

- State the hypothesis:

                      Null hypothesis : u2 - u1 > 0

                      Alternate hypothesis : u2 - u1 ≤ 0

- The rejection region of the T- critical for lower tailed test.

                      significance level, α = .05

                      degree of freedom v = n - 1 = 16 - 1 = 15

                      T-critical =  - 1.75

- The T-test value is compared with T-critical:

                      T-test = 1.94

                      T- critical = -1.75

                      T-test > T-critical  .. ( Null not rejected )

- Not enough statistical evidence to prove that treatment 2 sample mean u2 is less than treatment 1 sample mean u1. So the claim maybe supported.
