When solving x² - 10x-13-0 by completing the square, which equation is a step in the
process?
1) (x - 5)² = 38
2) (x - 5)² = 12
3) (x-10)² = 38
4) (x-10)² = 12
Answers
Answer:
1)
Step-by-step explanation:
\( {(x - 5)}^{2} = 38\)
The required step solving the equation using Completing the square method is (x - 5)² = 38.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
We have the Equation: x² - 10x-13 = 0
Now, half the coefficient of x and add and subtract the square of the half of the coefficient of x.
So, x² - 10x-13 = 0
x² - 10x-13 -5² + 5² = 0
(x - 5)² - 25 - 13 = 0
(x-5)² -38= 0
(x - 5)² = 38

Use the graph to answer questions. Part A Which inequality does graph representPart B Find two solutions to the graph and verify algebraically
Answers
For part A, first observe that the line in the graph is not dotted, but continuous, so you have an inequality of type ≤ or ≥.
Now, notice that if you take some random points on the Cartesian plane, for example, (5,6), (4,-3),(-3,6) and (-6,-7) the first and third points belong to the shaded region, while the second and fourth points do not.
As you can see in the points that if they belong to the shaded region, the y coordinate is greater than the x coordinate.
On the other hand, at the points that do not belong to the shaded region, the Y coordinate is less than the x coordinate.
Therefore, the inequality represented by the graph is
\(y\ge\frac{1}{2}x-1\)For part B, you can take, for example, the points or ordered pairs that you used in part A and replace in the inequality. So for (5,6) you have
\(\begin{gathered} y\ge\frac{1}{2}x-1 \\ 6\ge\frac{1}{2}(5)-1 \\ 6\ge\frac{5}{2}-1 \\ 6\ge\frac{3}{2} \\ 6\ge1.5 \end{gathered}\)Since you get a true statement then the point (5,6) is a solution. Now for (-3,6) you have
\(\begin{gathered} y\ge\frac{1}{2}x-1 \\ 6\ge\frac{1}{2}(-3)-1 \\ 6\ge\frac{-3}{2}-1 \\ 6\ge\frac{-5}{2} \\ 6\ge-2.5 \end{gathered}\)Since you get a true statement then the point (-3,6) is a solution too.
Therefore, two solutions to the graph are (5,6) and (-3,6).
The R command for calculating the critical value tos7 of the t distribution with 7 degrees of freedom is "qt(0.95, 7):" True False
Answers
True. The R command for calculating the critical value (tos7) of the t distribution with 7 degrees of freedom is "qt(0.95, 7)".
This command provides the t value associated with the 95% confidence level and 7 degrees of freedom based on t distribution.
When the sample size is small and the population standard deviation is unknown, statistical inference frequently uses the t-distribution, a probability distribution. The t-distribution resembles the normal distribution but has heavier tails, making it more dispersed and having higher tail probabilities. As a result, it is more suitable for small sample sizes. Using a sample as a population's mean, the t-distribution is used to estimate confidence intervals and test population mean hypotheses. It is a crucial tool for evaluating the statistical significance of research findings and is commonly utilised in experimental studies. Essentially, the t-distribution offers a mechanism to take into consideration the elevated level of uncertainty.

which of the following samples is used as a means of ensuring that convenience samples will have the desired proportion of different respondent classes? a. convenience sampling. b. judgement sampling. c. referral sampling. d.
Answers
Referral sampling is the method used to ensure that convenience samples will have the desired proportion of different respondent classes.
Convenience sampling is a non-probability sampling method that involves selecting participants who are readily available and easily accessible. However, convenience samples may not represent the entire population accurately, as they may introduce biases and lack diversity.
To address this limitation, referral sampling is often employed. Referral sampling involves asking participants from the convenience sample to refer other individuals who meet specific criteria or belong to certain respondent classes. By relying on referrals, researchers can increase the chances of obtaining a more diverse sample with the desired proportion of different respondent classes.
Referral sampling allows researchers to tap into the social networks of the initial convenience sample participants, which can help ensure a broader representation of the population. By leveraging the connections and referrals within the sample, researchers can enhance the diversity and representation of different respondent classes in the study, improving the overall quality and validity of the findings. Therefore, referral sampling is used as a means of ensuring that convenience samples will have the desired proportion of different respondent classes.

B.) The results are untrustworthy
C.) We would expect the results to occur by chance less than 95 times out of 100
D.) We would expect the results to occur by chance less than 5 times out of 100.
Answers
If researchers report that the results from their study were significant, p < .05, this means that we would expect the results to occur by chance less than 5 times out of 100.
What does it indicate when researchers report results with p < .05?When researchers report that the results from their study were significant, p < .05, it means that we would expect the results to occur by chance less than 5 times out of 100. This threshold is commonly used in statistical hypothesis testing.
In statistical hypothesis testing, the p-value represents the probability of obtaining results as extreme as the observed results, assuming that the null hypothesis is true. If the p-value is less than the predetermined significance level of .05 (or 5%), it is considered statistically significant. This means that the observed results are unlikely to have occurred by chance alone, and there is evidence to support the alternative hypothesis.
Therefore, option D, "We would expect the results to occur by chance less than 5 times out of 100," is the correct interpretation of reporting significant results with p < .05.

The monthly cost of driving a car depends on the number of miles driven. Lynn found that in May it cost her $356 to drive 380 mi and in June it cost her $404 to drive 620 mi. The function is C(d)=0.2+280 (b) Use part (a) to predict the cost of driving 1800 miles per month. (c) Draw a graph (d) What does the slope represent? What does the C-intercept represent? Why does a linear function give a suitable model in this situation?
(b) $640 (c) y-int of 280, positive slope (d) It represents the cost (in dollars) per mile. It represents the fixed cost (amount she pays even if she does not drive). A linear function is suitable because the monthly cost increases as the number of miles driven increases.
Answers
To predict the cost of driving 1800 miles per month, substitute 1800 in the given function C(d) = 0.2d + 280C(1800) = 0.2 (1800) + 280= $640 per month. Therefore, the cost of driving 1800 miles per month is $640.
(b) Graph is shown below:(c)The slope of the graph represents the rate of change of the cost of driving a car per mile. The slope is given by 0.2, which means that for every mile Lynn drives, the cost increases by $0.2.The y-intercept of the graph represents the fixed cost (amount she pays even if she does not drive).
The y-intercept is given by 280, which means that even if Lynn does not drive the car, she has to pay $280 per month.The linear function gives a suitable model in this situation because the monthly cost increases as the number of miles driven increases.
This is shown by the positive slope of the graph. The fixed cost is also included in the function, which is represented by the y-intercept. Therefore, a linear function is a suitable model in this situation.

Answers
Answer:
12f + 9.8g + 5.7 centimeters
Step-by-step explanation:
Side A = (9.8f-8.4) centimeters
Side B = (2.2f+4.9) centimeters
Side C = (9.8g+9.2) centimeters.
Perimeter of a triangle = Side A + Side B + Side C
= (9.8f-8.4) + (2.2f+4.9) + (9.8g+9.2)
= 9.8f - 8.4 + 2.2f + 4.9 + 9.8g + 9.2
Collect like terms
= 9.8f + 2.2f + 9.8g - 8.4 + 4.9 + 9.2
= 12f + 9.8g + 5.7 centimeters
Therefore, the expression which represents the perimeter of the triangle 12f + 9.8g + 5.7 centimeters
