Answer:

Sample because it's only the first ten games of the season not of all the games in the season

Step-by-step explanation:

Answer:

Sample but the power of a study is its ability to detect an effect when there is one to be detected. ... A sample size that is too small increases the likelihood of a Type II error skewing the results, which decreases the power of the study.

Within accompaniment order to be a population then it would need to be justifiable to be comparable to a larger cross section same teams different players that could be at the end of the season, and a population that shows cross section of change, such as the inevitable and include distractions that occur in sports as season starts and progresses till end. Examples of this would include ie) playing with man down etc. or against a team with man down or during penalties etc..

It only becomes a population when it defines all home games only being used as a population as this would show less distraction for each team. Which would be unlikely event in first 10 games, just like it would be unfair to not show the differences for away games within a population.

The higher proportion showing the whole season, thereafter would show population as things change too fast in seasonal events.

The required solution for Lines p, q, r, and s has been given.

Parallel lines are defined as identical lines with identical orientations, parallel lines never intersect each other but meet at infinity.

here,
Part A:

If line p || line q, then angles 1 and 2 are corresponding angles and have the same measure. Since angle 1 has a measure of 84°, angle 2 must also have a measure of 84°.

Part B:

If line r || line s, then angles 1 and 4 are alternate angles and have the same measure. Since angle 1 has a measure of 84°, angle 4 must also have a measure of 84°.

Part C:

In order for m∠1 = m∠6, line r must be a transversal that intersects lines p and q at points A and B respectively, such that angles 1 and 6 are corresponding angles. This means that angle 1 and angle 6 are in the same position relative to their respective parallel lines and therefore have the same measure.

Answer:

x≤4

Step-by-step explanation:

Step 1: Simplify both sides of the inequality.

−1/4

x≥−1

Step 2: Multiply both sides by 4/(-1).

(4−1)*(−14x)≥(4−1)*(−1)

Answer:

1. multiply both sides of the equality by -4 and flip the equality sign

that makes the problem: -4×x/-4 >_ -4×(-1)

2.since you multiplied -4 the divisor cancels and you are left with : x<_ -4×(-1)

multiplying 2 negatives makes it a positive so now you get x<_4

Answer:

  A.  f(0) = 4

  B.  f(6) = 8

Step-by-step explanation:

When evaluating a piecewise function, the fist step is to determine the applicable domain. Then the function defined for that domain is the one that is used for the evaluation.

x = 0 is in the domain x < 5, so the applicable function is f(x) = x+4.

  f(0) = 0 +4 = 4

__

x = 6 is in the domain 5 ≤ x < 7, so the applicable function is f(x) = 8.

  f(6) = 8

Answer:

24 miles

Step-by-step explanation:

50 minutes = 8 miles

100 miles = 16 miles

150 minutes = 24 miles

Answer:

Jason can travel 24 miles in 150 minutes.

Step-by-step explanation:

8= miles. 50&150= mins

8=50.

Your trying to find how many miles Jason can travel in 150 mins. So your going to divide the new amount of minutes to the old amount.

150÷50= 3.

So since 50 can go into 150 3 full times that means you will multiply the original amount of miles by 3 to get your new amount.

3×8= 24

So, if Jason can travel 8 miles in 50 mins (8=50) Then, he can travel 24 miles in 150 mins (24=150)

Hope this wasn't too confusing,

Hope this helps!

The equation of a line that passes through the point (1,-5) with slope -1 is y = -x - 4.

Given:

(1,-5) with slope m = -1

The standard slope intercept form is y = mx + c.

substitute m = -1 and (1,-5)

-5 = -1(1) + c

-5 = -1 + c

c = -4.

y = mx + c

y = -1(x) + (-4)

y = -x - 4.

Therefore the equation of a line that passes through the point (1,-5) with slope -1 is y = -x - 4.

Therefore equation of a line that passes through the point (1,-5) with slope -1 is y = -x - 4.

Therefore, another set of values for r and h that could be used to make a cylinder with a volume that is 8 times greater than the given soda can are r = 6 cm and h = 24 cm

The given soda can has a radius of 3 cm and a height of 12 cm. The formula for the volume of a cylinder is V = πr²h where r is the radius and h is the height of the cylinder.

To find the radius and height of a cylinder that has a volume 8 times greater than the given soda can, we need to multiply the volume of the soda can by 8, and then solve for the radius and height of the cylinder.

Volume of the given soda can = π(3 cm)²(12 cm) = 339.292 cm³

Volume of the cylinder with 8 times the volume of the soda can = 8 × 339.292 cm³ = 2714.336 cm³

Now, we can substitute the values of V and r²h into the formula V = πr²h and simplify it to solve for the possible values of r and h.πr²h = 2714.336 cm³

Substituting the value of V and r²h, we get:π( r²)(h) = 2714.336

Dividing both sides by π, we get:r²h = 864 cm³

Solving for r and h using the given values:

r = 3 cm

h = 12 cm

Substituting these values in the equation:

r²h = 3² × 12 = 108 cm³

Since r²h = 864 cm³, we can find another set of values for r and h by dividing 864 cm³ by 108 cm³ and multiplying both r and h by that same factor.864 ÷ 108 = 8

Multiplying both r and h by 8, we get:

r = 3 cm × 2 = 6 cm

h = 12 cm × 2 = 24 cm

Therefore, another set of values for r and h that could be used to make a cylinder with a volume that is 8 times greater than the given soda can are r = 6 cm and h = 24 cm

a) The dot product of the first two vectors is not zero but the dot product of the second pair is zero, the given vectors are not orthogonal.

b)  The given vectors are linearly independent.

a) To check if the given vectors are orthogonal, we need to compute the dot products of each pair of vectors and verify that the dot product is zero for all pairs:

(1,1,-1) . (2,0,1) = 2 + 0 - 1 = 1

(1,1,-1) . (0,3,3) = 0 + 3 - 3 = 0

(2,0,1) . (0,3,3) = 0 + 0 + 3 = 3

Since the dot product of the first two vectors is not zero but the dot product of the second pair is zero, the given vectors are not orthogonal.

b) To check if the given vectors are linearly independent, we need to determine whether there exist non-zero constants c₁, c₂, and c₃ such that

c₁(1,1,-1) + c₂(2,0,1) + c₃(0,3,3) = (0,0,0)

This leads to the system of equations:

c₁ + 2c₂ = 0

c₁ + 3c₃ = 0

-c₁ + c₂ + 3c₃ = 0

We can solve this system using elimination or substitution. Without going into details of elimination or substitution, we obtain c₁ = 0, c₂ = 0, and c₃ = 0 as the only solution. This means that the only linear combination of the given vectors that produces the zero vector is the trivial one, where all coefficients are zero.

Therefore, the given vectors are linearly independent.

Where W is the width, L is the length, and x is defined by where she divides the rectangle.

So originally, we have a rectangle of length L and width W.

Let's assume that tina divides the length, by cutting "x" of the length to make one of the rectangles.

Then, we have two rectangles of width W, and one has a length of (L - x) and the other has a length of x. (A diagram of this can be seen below).

Then the area of these two rectangles will be:

A = W*(L - x)

A' = W*x

Answer:

Step-by-step explanation:

The perimeter is equal to 14x + 8 but it is also equal to 2a + 2b, so

14x + 8 = 2(4x - 4) + 2b

14x + 8 = 8x - 8 + 2b

Let's move 2b to the other side of the equation, we get:

14x + 8 - 2b = 8x - 8

Now, let's move 14x + 8 to the other side too to find what -2b is equal to

-2b = 8x - 14x + 8 - 8

Gonna simplify:

-2b = -6x

Now, let's multiply both sides with -1 to find what 2b is equal to

-2b * -1 = -6x * -1

2b = 6x

Now, we know that 2*b is equal to 6x, but we need to find what side b is equal to, so we gonna divide 6x by two to get what b is equal to

2b = 6x

b = 3x

Side b is equal to 3x

The time that the plane left London City Airport, given the average speed of the plane and the miles flown, is 17 : 55

To find the time that the plane left London City airport, find the number of hours the plane spent flying the 256 miles distance at an average speed of 192 mph.

The time can be found by the formula :

= Distance / Speed

= 256 / 192

= 1 .33 hours

0.33 hours in minutes is:

= 0.33 x 60 minutes per hour

= 20 minutes

So the time spent flying was 1 hour 20 minutes

If the plane arrived at 19 : 15 then it must have left at :
