Answer:c=8

Step-by-step explanation:

AB + BC = AC

6c-8 + 3c+1 =65 (simplify)

9c -7 =65 (combine like terms) (cancel out the -7 by adding 7 to both sides).

9c = 72 (Divide both sides by 9 to get c by itself.

c=8

Then substitute c for 8

AB = 6(8)-8 = 40

BC = 3(8)+1 = 25

AC = 40 + 25 =65

Step-by-step explanation:

The probability of getting a sum of 5 when rolling 3 dice is approximately 0.0972

To find the probability of getting a sum of 5 when rolling 3 dice, we can use the concept of generating functions. The generating function for rolling a single die is:

(x + x^2 + x^3 + x^4 + x^5 + x^6)

To find the generating function for rolling 3 dice, we can simply multiply the generating functions for a single die together:

(x + x^2 + x^3 + x^4 + x^5 + x^6)^3

We are interested in finding the coefficient of the x^5 term in the expansion of this generating function, since this represents the number of ways we can roll 3 dice to get a sum of 5.

We can simplify the problem by using symmetry. The generating function for rolling a single die is symmetric around the term x^3. Therefore, we can rewrite the generating function for 3 dice as:

(x^3 + x^4 + x^5 + x^6 + x^7 + x^8)^3

Now we just need to find the coefficient of the x^2 term in this simplified generating function. Therefore, the number of ways to roll 3 dice to get a sum of 5 is:

C(5+3-1,3-1) = C(7,2) = 21

The total number of possible outcomes when rolling 3 dice is 6^3 = 216, since each die can have 6 possible outcomes. Therefore, the probability of getting a sum of 5 when rolling 3 dice is:

21/216 = 0.0972 (rounded to four decimal places)

So the probability of getting a sum of 5 when rolling 3 dice is approximately 0.0972, or about 9.72%.

Answer:

C. 98

Step-by-step explanation:

The proposed regression equation is weight = b + width * m

R2 = 0.423

A.) What is the regression equation for this example?

The estimate for the y-intercepts is b= 2.3013 and the estimate for the slope is m= 0.7963

In general, we can symbolize the estimated regression equation as ^Y= b + m*Xi. For this example you have to replace it with the calculated values of the regression coefficients to obtain the estimated regression equation:

^Y= 2.3013 + 0.7963Xi

B.) What is the explanatory, or predictor, variable in this study?

The explanatory or predictor variable is the variable that is suspected to have an effect over the response variable. In this example the predictor variable is:

X: Width of a horseshoe crab (cm)

C.) If the researcher wanted to test whether there is a statistically significant relationship between these two variables, what would the test statistic be? Calculate it from the table above.

To test if the regression is significant, the parameter of study will be the slope of the regression equation, symbolically: β. If the slope is equal to zero "β=0" then there is no linear regression between the response and explanatory variable. If the slope is different from zero "β≠0" then the regression is significant and the explanatory variable affects the response variable.

The hypotheses are:

H₀: β=0

H₁: β≠0

α: 0.05

The value of the statistic under the null hypothesis is t= 8.48

D.) What can we say about the p-value?

This test is two-tailed and so is the p-value, remember that the p-value is the probabulity of obtaining a value as extreme as the value of the statistic under the null hypothesis. The distribution for this test is a t with n-2= 100-2= 98 degrees of freedom. You can calculate the p-value as:

P(t₉₈≤-8.48) + P(t₉₈≥8.48)= P(t₉₈ ≤ -8.48) + (1 - P(t₉₈ < 8.48) ≅ 0.00001

E.) Ultimately, the reason that we find test statistics is so that we can compare them to a null distribution. For regression, that is a t-distribution based on the degrees of freedom. With 98 degrees of freedom (100-2), we can safely say that the critical t (or the confidence multiplier) is what?

As mentioned before, this test is two tailed, meaning that the rejection region is divided in two:

Critical values ± = ± = ± 1.984

This means that you'll reject the null hypothesis when the statistic is t ≤ -1.984 or if the statistic is t ≥ 1.984-

F.) Find the confidence interval for the slope.

Using a 95% confidence level, the interval for the slope is:

[m ± Sm]

[0.7963 ± 1.984 * 0.0939]

[0.61; 0.98]

G.) Is there a statistically significant relationship? Answer with the test statistic and the confidence interval.

Yes, there is a significant relationship between the width and weight of the horseshoe crabs.

Using the critical value approach:

The calculated statistic is 8.48 and the critical value is ± 1.984, since the statistic is greater than the positive critical value, the decision is to reject the null hypothesis.

If you pay attention to the confidence interval, which was made at a confidence level complementary to the significance level of the hypothesis test, this interval [0.61; 0.98] doesn't include the "zero". Since the interval doesn't include the value of the parameter stated in the null hypothesis, you can conclude that this hypothesis is not true and therefore reject it.

Slope (m) = 1

At data point (5, 60) and a slope of 1, a linear equation for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 60 = 1(x - 5)  

y = x - 5 + 65

y = x + 60

Part a.

Based on the equation above, the y-intercept is equal to 60.

Part b.

Based on the equation above, the slope is equal to 1.

Nate has a deductible of $1,000, which means he is responsible for paying that amount out of pocket before his insurance coverage kicks in. The cost of repairing his car is $7,000, which exceeds his deductible.

However, Nate's collision coverage limit is $5,000, which is the maximum amount his insurance will cover for repairs.

Since the cost of repairs exceeds Nate's coverage limit, he will have to pay the difference between the coverage limit and the actual repair cost.

In this case, Nate's out-of-pocket expenses would be $7,000 (repair cost) - $5,000 (coverage limit) = $2,000.

By employing given tools, veterinarians can make evidence-based decisions, enhance patient care, and improve overall animal health outcomes.

Probability, data, trends, likelihoods, and statistics are used in various aspects of veterinary medicine to inform decision-making, assess risk, and improve patient outcomes.

Here are some specific examples:

Epidemiology and Disease Surveillance: Veterinarians use probability and statistics to track and analyze disease trends in animal populations. By collecting and analyzing data on disease occurrence, veterinarians can identify patterns, determine risk factors, and develop strategies for prevention and control.

Diagnostic Testing: Veterinary medicine often relies on diagnostic tests to detect and confirm the presence of diseases in animals. Probability plays a crucial role in interpreting test results. Veterinarians use statistics to determine the sensitivity (the probability of a positive test result given that the disease is present) and specificity (the probability of a negative test result given that the disease is absent) of different tests. These measures help assess the accuracy and reliability of diagnostic tests and guide treatment decisions.

Clinical Research and Evidence-Based Medicine: Probability, data, and statistics are fundamental in conducting clinical research in veterinary medicine. Researchers use statistical analysis to evaluate the effectiveness of treatments, compare different interventions, and assess clinical outcomes. This allows veterinarians to make evidence-based decisions when selecting treatments and managing patients. Additionally, statistics help determine sample sizes, calculate confidence intervals, and perform statistical tests to determine the significance of research findings.

Pharmacology and Drug Efficacy: Probability and statistics are used to assess the effectiveness and safety of medications in veterinary medicine. Clinical trials employ statistical methods to determine the optimal dosage, evaluate drug interactions, and assess the likelihood of adverse effects. These statistical analyses help veterinarians understand the benefits and risks associated with specific drugs, enabling them to make informed decisions when prescribing medications.

Risk Assessment and Predictive Modeling: Veterinarians often use probability and statistics to assess risks and predict outcomes in various scenarios.

Answer:

Triangle PQR maps onto triangle KLM. This is possible because △PQR ≅ △KLM by ASA, and one congruent figure can be mapped onto another using rigid motions.

Step-by-step explanation:

For the first blank, we are given congruence statements for 1 side on each triangle and their two adjacent angles. This means we can use the Angle-Side-Angle theorem to declare △PQR and △KLM congruent.

For the second blank, we know that rigid transformations do not change the figure, they simply move its position on a plane, so this is the correct answer; had the △PQR and △KLM not been congruent, a non-rigid transformation would have to have occured, but this is not the case here.

Answer:

Step-by-step explanation:

Given triangles PQR and KLM with QR ≅ LM, ∠Q ≅ ∠L, and ∠R ≅ ∠M, you want to know the applicable congruence postulate and whether the triangles are mapped to each other by rigid or non-rigid motion.

The segment QR has angle Q at one end and angle R at the other end. That means the side lies between the two angles. Likewise, segment LM lies between angles L and M.

When claiming congruence of these triangles, the appropriate postulate is the one that refers to the geometry with the congruent side between the congruent angles: ASA.

"Rigid" motion is motion that preserves angle and length measures. By contrast, "non-rigid" motion may involve stretching or compression in one or more directions. It may or may not preserve angles or lengths.

Congruence is about showing that angles and lengths are the same from one figure to another. If you want to map congruent figures to each other, you must do so using rigid motion.

Step-by-step explanation:

I DON'T KNOW

Answer:

m<P = 50°

Step-by-step explanation:

Given:

Arc CE = 82°

Arc DF = 98°

Ratio of arc CD to Arc EF = 2:7

Thus, let,

Arc CD = 2x

Arc EF = 7x

A full circle = 360°

Therefore,

Arc CE + Arc DF + Arc CD + Arc EF = 360°

Substitute

82° + 98° + 2x + 7x = 360°

Add like terms

180° + 9x = 360°

Subtract 180° from both sides

180° + 9x - 180° = 360° - 180°

9x = 180°

Divide both sides by 9

9x/9 = 180/9

x = 20

✔️Arc CD = 2x

Plug in the value of x

Arc CD = 2(20) = 40°

Arc EF = 7x = 7(20) = 140°

✔️Find m<P:

Recall: the measure of the external angle created when two secants intersect = half the difference of the major and minor arcs that are intercepted

Thus:

m<P = ½(arc EF - arc CD)

Substitute

m<P = ½(140° - 40°)

m<P = ½(100°)

m<P = 50°
