The correlation coefficient is increasing, which may have an effect on the influential points. Thus, option (a) is correct.

The correlation coefficient, in general, quantifies the strength of the association between two variables.

To find non-linearity, influential spots, or improper grouping in a dataset, for example. A scatter plot is used to graph the data set.

Here, the correlation coefficient is r = 0.813.

Linearity is evident since there is a significant link between the two variables. As a result, non-linearity has no effect on it. It is not influenced by incorrect categorization when it appears that type of case correlation may be lower.

The correlation coefficient is increasing, which may have an effect on the influential points.

Answer:

(1.5, -3)

Step-by-step explanation:

Both equations are in slope intercept form which means that:

for y = mx + b

m = slope

b = y-intercept

The slope can help us go from the y-intercept to the next point on the graph to make the line

For the equation

y = 2x - 6

the y-intercept is -6, so plot a point there.

The slope is 2 which means you will go up 2 then to the right by 1  to the next point on the graph.

Use the same process to find the line for y = -4x + 3, but you have to keep in mind that when the "m" value is negative, that means the line will point to the left of the graph instead of the right.

Once the lines are draw, the point where they intercept will be the solution.

The weight of the other apple is 250 grams.

As per the given data:

The weight of 2 apples is 400 gram.

The weight of 1 apple is 150 grams which I ate.

We have to determine the weight of the other apple.

Subtract the weight of 1 apple from weight of 2 apples

Subtraction is the process of taking away a number from another. It is a primary arithmetic operation that is denoted by a subtraction symbol (-) and is the method of calculating the difference between two numbers

One value is 400 and the other value is 150.

Means subtract 150 from 400.

The weight of the other apple = Weight of 2 apples - The weight of 1 apple

= 400 - 150

= 250 grams

Therefore the answer is 250 grams.

She completed one training day in a triathlon- 62.5 km.

Convert meter to kilometer :

               1 kilometer = 1000 meter

          ⇒  1 meter = [tex]\frac{1}{1000}[/tex] kilometer

On a training day, she swam = 1500 meter

                                                 = [tex]\frac{1500}{1000}[/tex] kilometer

                                                 = 1.5 kilometer

She rode a bike = 47000 meter

                           = [tex]\frac{47000}{1000}[/tex] kilometer

                           = 47 kilometer

She ran = 14 km

We may get the total distance by adding the distances she covered with swimming, riding, and running.

∴ Total distance she covered for a triathlon = ( 1.5 + 47 +14) km

                                                                         = 62.5 km

To draw a linear inequality in graph the steps are mentioned below.

The graph of a two-variable inequality is the set of points that describe all solutions to the inequality. The coordinate plane is split in half by a boundary line created by a linear inequality, with one-half representing the solutions to the inequality.

Steps are described below:

Step 1: Always begin by separating the variable y from the inequality's left side.

Step 2: Replace the symbol for inequality with that for equality.

Step 3: In the xy plane, graph the boundary line from step 2. You are creating the boundary line that would divide or cut the xy-plane into two sections in this stage.

Step 4: Shading one side or area of the boundary line is the final step.

Step 5: Use this optional step to check or confirm that you have shaded the boundary line's side appropriately.

3/5 is the quotient of these fractions in lowest form when 3/10 divides by 2/4

When two fractions are divided, the first fraction is multiplied by the second fraction's reciprocal. Finding the reciprocal of the second fraction and this can be obtained by reversing its numerator and denominator—is and then dividing the  fractions. Multiply the two numerators after that. Multiply the two denominators after that, After that we need to simplify the fraction to its lowest form.

so in order to find quotient when 3/10 is divided by 2/4 we get:

quotient = (3/10) / (2/4)

=> (3/10) * (4/2)

=> 12/20

so the quotient of this division is 12/20

now we have to find the lowest form of quotient

so gcd(12,20) = 4

Without spectacles, Witney Pete has a 5/10 chance of hitting the bullseye. Witney Pete could strike the bullseye with his spectacles 0.7 of the time. This likelihood is far higher than hitting the bullseye without glasses. the probability that Pete hits five or fewer of his next ten shots is approximately 2.487.

Generally, To find the probability that Pete hits five or fewer of his next ten shots, we need to find the probability that he hits exactly 0, 1, 2, 3, 4, or 5 bull's eyes.

The probability that Pete hits exactly k bull's eyes in n throws is given by the binomial distribution:

P(k bull's eyes in n throws) = (n choose k) * p^k * (1-p)^(n-k)

where p is the probability of hitting a bull's eye on a single throw and n choose k is the binomial coefficient, which is equal to n!/(k!(n-k)!).

Substituting the given values, we get:

P(0 bull's eyes in 10 throws) = (10 choose 0) * (0.7)^0 * (0.3)^10 = 0.028 P(1 bull's eyes in 10 throws) = (10 choose 1) * (0.7)^1 * (0.3)^9 = 0.189 P(2 bull's eyes in 10 throws) = (10 choose 2) * (0.7)^2 * (0.3)^8 = 0.462 P(3 bull's eyes in 10 throws) = (10 choose 3) * (0.7)^3 * (0.3)^7 = 0.605 P(4 bull's eyes in 10 throws) = (10 choose 4) * (0.7)^4 * (0.3)^6 = 0.501 P(5 bull's eyes in 10 throws) = (10 choose 5) * (0.7)^5 * (0.3)^5 = 0.302

The probability that Pete hits five or fewer bull's eyes in his next ten shots is the sum of the probabilities of hitting exactly 0, 1, 2, 3, 4, or 5 bull's eyes:

P(hitting 5 or fewer bull's eyes in 10 shots) = 0.028 + 0.189 + 0.462 + 0.605 + 0.501 + 0.302 = 2.487

Step-by-step explanation:

The measure of angle SXU is m ∠SXU = 128°.

What is linear angles?

If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°. These are also referred to as supplementary angles. Angles that share a vertex are said to be adjacent.

Given: m ∠RXU = 52°

We have to find the measure of angle m ∠SXU.

Let RS and VW are two lines intersects by a transversal TU.

∠3 and ∠4 are adjacent to each other after the intersection of the two lines.

Since the sum of angles of a linear pair is always equal to 180°.

⇒ ∠3 + ∠4 = 180°

52° + ∠4 = 180°

∠4 = 180° - 52°

∠4 = 128°

Hence, the measure of angle SXU is m ∠SXU = 128°.

Answer:

3.82 km

Step-by-step explanation:

Assuming that the change in elevation is linear, we can calculate the elevation change per km traveled.  The known values are the start (0km) and the sign (3km).  The elevation gain over that interval is (0.95-9.0)km = 0.5km.  That was for an distance interval of  3km, so we can write:

(0.5km elevation gain)/(3km distance)

We can use this as a rate change and and use it in a linear equation to predict the elevation as a function of distance.

Let y be the elevation and x the distance, both in km.

y = (0.183)(x)+b, where b is the elevation at the start of the trail.  We can find b by using this equation and entering one of the two data points.  Lets use the elevation of 0.95m at 3km distance:

y = (0.183)(x)+b

0.95 = (0.183)(3)+b

b = 0.4km

The full equation is :

y = (0.1833)X + 0.4

Enter 1.1 km for y and calculate x, the distance to reach 1.1 km altitude.

1.1 = (0.1833)X + 0.4

X = 3.82 km
