An observation that has a strong effect on the regression results is called a(n) O a. influential observation b. residual O c. sum of squares error d. None of these answers are correct.
The correct answer to the question is option a) influential observation. An influential observation is an observation that has a significant impact on the regression results, meaning that if it is removed, the regression equation and the coefficients can change significantly.
In other words, it can have a strong effect on the fit of the regression model.
For instance, an influential observation could be an outlier, a point that deviates significantly from the general pattern of the data. This point can affect the slope and intercept of the regression line, and therefore the predictions and inference based on the model. Another example of an influential observation could be a point that has a high leverage, meaning that it has a high leverage on the estimated coefficients due to its position in the predictor space.
Therefore, it is essential to detect and address influential observations when building regression models to ensure that the results are reliable and valid. Techniques such as Cook's distance and leverage plots can be used to identify influential observations and various methods can be employed to deal with them, such as removing them, transforming the data, or using robust regression techniques.

The marked price of fan is Rs.1250, and the shopkeeper allows a discount of 6% on it . Find the selling price of the fan .
Given:;
Marked price of a fan = Rs. 1250.
Discount percent = 6%.
To find:
The selling price of the fan.
Solution:
We have,
Marked price of a fan = Rs. 1250.
Discount percent= 6%.
So,
Selling price = Marked price - Discount
\(S.P.=1250-\dfrac{6}{100}\times 1250\)
\(S.P.=1250-75\)
\(S.P.=1175\)
Therefore, the selling price of the fan is Rs. 1175.

The volume of a cube is 681472 cubic cm. Find the side of the cube.
Answer:
\(l = 88 cm\)
Step-by-step explanation:
Volume of Cube = \(l*l*l\)
Volume of Cube = \((Length)^3\)
Where volume = 681472 cubic cm
=> \(l^3 = 681472\)
Taking square root on both sides
=> \(l = \sqrt{681472}\)
=> \(l = 88 cm\)

Evaluate for b:
-5/6b = 30
Answer:
b = -36
Step-by-step explanation:
In other words, solve this given equation -5/6b = 30 for b.
For clarity we rewrite this as (-5/6)b = 30.
To isolate b, we multiply both sides of the above equation by (-6/5):
(-6/5)(-5/6)b = (30)(-6/5), or
b = -36

A CBS News/New York Times opinion poll asked 1,190 adults whether they would prefer balancing the federal budget over cutting taxes; 59% of those asked said "yes." Suppose that in fact 62% of all adults favor balancing the budget over cutting taxes. If this poll was not biased, what is the probability you would get p^=0.59 or less?
Using the normal distribution and the central limit theorem, it is found that there is a 0.0166 = 1.66% probability of a sample proportion of 0.59 or less.
In a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X. By the Central Limit Theorem, the sampling distribution of sampling proportions of a proportion p in a sample of size n has mean \(\mu = p\) and standard error \(s = \sqrt{\frac{p(1 - p)}{n}}\)In this problem:
1,190 adults were asked, hence \(n = 1190\)In fact 62% of all adults favor balancing the budget over cutting taxes, hence \(p = 0.62\).The mean and the standard error are given by:
\(\mu = p = 0.62\)
\(s = \sqrt{\frac{p(1 - p)}{n}} = \sqrt{\frac{0.62(0.38)}{1190}} = 0.0141\)
The probability of a sample proportion of 0.59 or less is the p-value of Z when X = 0.59, hence:
\(Z = \frac{X - \mu}{\sigma}\)
By the Central Limit Theorem
\(Z = \frac{X - \mu}{s}\)
\(Z = \frac{0.59 - 0.62}{0.0141}\)
\(Z = -2.13\)
\(Z = -2.13\) has a p-value of 0.0166.
0.0166 = 1.66% probability of a sample proportion of 0.59 or less.

Max loves fishing. He and his family chartered a fishing boat that left Florida and traveled towards the Bahama Islands at an average speed of 10 km/hour. Some time later a cruise ship left traveling in the same direction but at an average speed of 14 km/hour. After traveling for ten hours the cruise ship caught up with the fishing boat. How long did the fishing boat travel before the cruise ship caught up?
The fishing boat traveled for 14 hours before the cruise ship caught up.
In this question, we have been given Max and his family chartered a fishing boat that left Florida and traveled towards the Bahama Islands at an average speed of 10 km/hour.
After some time, a cruise ship left traveling in the same direction but at an average speed of 14 km/hour.
The cruise ship caught up with the fishing boat after traveling for 10 hours.
Let a cruise traveled 'm' km after 10 hours.
Using the formula of speed,
speed = distance / time
14 = m / 10
m = 14 * 10
m = 140 km
This means, a cruise traveled 140 km in 10 hours.
Now, we find the time needed for a fishing boat to cover 140 hours.
speed = distance / time
10 = 140/t
t = 140 / 10
t = 14 hours
Therefore, the fishing boat traveled for 14 hours before the cruise ship caught up.

Use the initial term and the recursive formula to find an explicit formula for the sequence an. Write your answer in simplest form.
Answer:
\(a_n = -11-14n\)
Step-by-step explanation:
Given
\(a_1 = -25\)
\(a_n = a_{n-1}-14\)
Required
The explicit formula
First, calculate \(a_2\)
Set n=2; So:
\(a_2 = a_{2-1}-14\)
\(a_2 = a_{1}-14\)
Substitute -25 for \(a_1\)
\(a_2 = -25-14\)
\(a_2 = -39\)
Calculate the common difference (d)
\(d = a_2 - a_1\)
\(d = -39 --25\)
\(d = -14\)
So, the nth term is:
\(a_n = a_1 + (n - 1)d\)
\(a_n = -25+ (n - 1)*-14\)
Open bracket
\(a_n = -25-14n + 14\)
Collect like terms
\(a_n = 14-25-14n\)
\(a_n = -11-14n\)

Answer
linear
nonproportional
Step-by-step explanation:
Since for each equal change in time (1 week), there is an equal change in weight (5 lb), the situation is linear.
At time zero, the first week, the weight was not zero. It was 60 lb, so it is not proportional.

The equation of line line a gis y = (startfraction b over a c endfraction)x. the midpoint of bc is (a c, b). does the midpoint of bc lie on line a g? why or why not? no, because (startfraction b over a c endfraction)b does not equal a c no, because (startfraction b over a c endfraction)(a c) does not equal b yes, because (startfraction b over a c endfraction)b = a c yes, because (startfraction b over a c endfraction)(a c) = b
yes, because the midpoints (a+c) = b
Given that the line's equation is y=x.
B and C are the two points on this line.
( a+ c, b) is the midpoint of B and C.
We can see from this that using the midpoint formula
a + c = \(\frac{x1+x2}{2}\)
b=\(\frac{y1+y2}{2}\)
Because both points are on y=x, we get
x1=y1, x2=y2.
As a result, x1 = a+c and 2y1 = 2b or y1 =b.
Because x1=y1, we have a+c =b.
In other words, the coordinates of the midpoint satisfy the equation y=x.
Thus, the answer is
because (a+c) = b
