Answer:

C

Step-by-step explanation:

-2 means that the y-intercept is (0, -2), so we can immediately eliminate option D. 3x means that it is a positive correlation, so left to right the line will go diagonally up, so we can eliminate option B.

Finally, we can see that 3x means that the slope is pretty steep, so we can choose C as our answer.

The angle between vectors v = -2i + 5j, w = 4i + 12j is approximately 41.66 degrees.

To find the angle between two vectors, we can use the dot product formula:

v · w = |v| |w| cosθ

where v · w is the dot product of vectors v and w, |v| and |w| are the magnitudes of v and w respectively, and θ is the angle between them.

Let's calculate the dot product of v and w:

v · w = (-2)(4) + (5)(12) = -8 + 60 = 52

Next, we need to calculate the magnitudes of v and w:

|v| = √((-2)² + 5²) = √(4 + 25) = √29

|w| = √(4² + 12²) = √(16 + 144) = √160 = 4√10

Now, we can substitute the values into the formula to find the cosine of the angle:

52 = (√29)(4√10) cosθ

Simplifying the equation:

cosθ = 52 / (4√29 √10)

cosθ = 13 / (√290)

cosθ ≈ 0.7616

To find the angle θ, we take the inverse cosine (arccos) of the value:

θ = arccos(0.7616)

Using a calculator, we find θ ≈ 41.66 degrees.

Answer:

The probability that a player selected at random does not bat left-handed is 20%.

Step-by-step explanation:

Assume that there are a total of 100 baseball players at an elite baseball camp.

The information provided is:

That is, the number of players can bat both right-handed and left-handed is,

n (L and R) = 60.

Now, if 25% of the players who bat left-handed do not bat right-handed, then 75% of all left-handed players can also bat right-handed.

⇒ n (L and R) = n (L) × 75%

            60     = n (L) × 0.75

           n (L)    =  60/0.75

           n (L)    = 80

So there are 80 left handed batters.

Compute the number of only left handed batters as follows:

n (Only L) = n (L) × 25%

                = 80 × 0.25

                = 20

So there are 20 only left handed batters.

Compute the number of only right handed batters as follows:

Total = n (Only L) + n (Only R) + n (L and R)

 100 = 20 + n (Only R) + 60

n (Only R) = 20

Thus, the probability that a player selected at random does not bat left-handed is 20%.

The total number of outcomes where all three dice show different numbers is 120.

To determine the number of outcomes in which all three dice show different numbers, you can use the multiplication principle. First, choose a number on the red die (6 options). Then, choose a different number on the blue die (5 options, since it cannot be the same as the red die). Finally, choose a different number on the green die (4 options, since it cannot be the same as the red or blue die). Multiply the options together: 6 x 5 x 4 = 120. Therefore, there are 120 possible outcomes in which the three dice all show different numbers.

The best estimate for the owl population is 2,378.

The population of the owl can be estimated using the concept of proportion. Proportion refers to a mathematical comparison between two numbers. According to the concept, if two sets of given numbers are increasing or decreasing in the same ratio, hence the ratios are said to be directly proportional to each other.

Based on the provided information, 29 owls are tagged and released as part of a research project. Assume that the total number of owl populations is x. At the later time, researchers counted 902 owls and found the 11 were tag. Hence, there are 18 tagged owls which are not accounted for. Assuming that the proportional of tagged owls to number of owls counted applies to the remaining population, the total number of owls can be best estimated as:

Answer: $7.65 for a dozen/12

Step-by-step explanation: 2.55 x 3

The class width is 15.175 with the first class limit as 12 and the last class limit as 72.7. The lower class limits are 12, 27.175, 42.35, and 57.525. The upper class limits are 27.175, 42.35, 57.525, and 72.7.

The given minimum and maximum data entries are 12 and 72.7 respectively with 4 classes. In order to find the class width, first, the range is found by subtracting the minimum value from the maximum value. Therefore, the range in this case is (72.7-12) = 60.7. The number of classes given is 4. The formula to find the class width is:

Class width = Range/Number of classes

Therefore, Class width = 60.7/4 = 15.175.

The first class limit is the minimum value itself, i.e., 12. The last class limit is the maximum value itself, i.e., 72.7. The lower class limits and upper class limits can be found by adding and subtracting the class width to and from the previous and subsequent class limits respectively.

The first lower class limit is the same as the minimum value, which is 12. The first upper class limit is the sum of the first lower class limit and the class width. Therefore, the first upper class limit is 12+15.175=27.175. The second lower class limit is the sum of the first upper class limit and 0.001 (to avoid overlapping of classes), which is 27.175+0.001=27.176.

The second upper class limit is the sum of the second lower class limit and the class width. Therefore, the second upper class limit is 27.176+15.175=42.35. The third lower class limit is the sum of the second upper class limit and 0.001 (to avoid overlapping of classes), which is 42.35+0.001=42.351. The third upper class limit is the sum of the third lower class limit and the class width.

Therefore, the third upper class limit is 42.351+15.175=57.525. The fourth lower class limit is the sum of the third upper class limit and 0.001 (to avoid overlapping of classes), which is 57.525+0.001=57.526. The fourth upper class limit is the same as the maximum value, which is 72.7.

One major difference in the style Shakespeare uses for Lady Macbeth's sleepwalking scene is the use of prose instead of verse. He does this to emphasize her confusion and disorientation, as well as create a sense of tension in the scene.

Shakespeare uses text rather than verse for Lady Macbeth's sleepwalking episode, which is a significant departure from his usual usage of verse. In addition to heightening the tension in the moment, he does this to highlight her confusion and disorientation.

Shakespeare uses prose to represent Lady Macbeth's disturbed mental state and her inability to express her thoughts coherently. In contrast, Macbeth speaks in verse throughout the play, expressing his thoughts in a logical and articulate manner. This contrast serves to further highlight Lady Macbeth's mental state and to illustrate the dramatic change in her character following the murder of Duncan.

Step-by-step explanation:

To find out how much it'll cost Melissa to buy the ribbon, we simply need to find all the side lengths (the perimeter) and then multiply then by the cost.

We already know two of the side lengths: 6 and 8. To find the third, remember that the question tells us that the triangle is a right triangle. Therefore, we can use the Pythagorean Theorem. The unknown side is the longest side. Therefore:

\(a^2+b^2=c^2\)

Substitute 6 for a and 8 for b. This gives us:

\((6)^2+(8)^2=c^2\)

Solve for c. Square the values:

\(36+64=c^2\)

Add:

\(100=c^2\)

Take the square root of both sides:

\(c=10\)

Therefore, our unknown side is 10 feet.

Therefore, the sum of our side lengths or the perimeter is:

\(P=6+8+10\)

Add:

\(P=24\text{ feet}\)

This means that the total cost will be:

\(T=\frac{0.82\text{ dollars}}{\text{foot}}\cdot24\text{ feet}\)

Multiply. The foot/feet cancel:

\(T=24(0.84)\text{ dollars}\)

Multiply:

\(T=\$19.68\)

So, it will cost Melissa a total of $19.68 to buy the ribbon.

And we're done!

Step-by-step explanation:

Bearing of Q from P = 72 degrees

Bearing of R from Q=320 degrees

Therefore, the second angle of Q is 50 degrees.

\(\angle P=72^\circ\\\angle Q=68^\circ\\\angle R=180^\circ-(72^\circ+68^\circ)=40^\circ\)

Using Law of Sines

\(\dfrac{r}{\sin R} =\dfrac{p}{\sin P} \\\dfrac{24}{\sin 40} =\dfrac{p}{\sin 72} \\p=\sin 72 \times \dfrac{24}{\sin 40}\\\\p=RQ=35.51$ km\)

In order to determine the number of permutations of the set {1, 2, · · · , 14} in which exactly 7 integers are in their natural positions, we can use the following formula:\($$\binom{n}{k} \cdot D_{n-k}$$\) Where n is the number of elements in the set, k is the number of elements in their natural positions, and D is the number of derangements of the remaining (n-k) elements.

So for this problem, we have n = 14 and k

= 7. The number of derangements of the remaining 7 elements is given by: \($D_7 = 7!\left(1 - \frac{1}{1!} + \frac{1}{2!} - \frac{1}{3!} + \cdots + \frac{(-1)^7}{7!}\right)$$D_7 = 7! \cdot \frac{223}{720}\)

= 18144$ Therefore, the number of permutations of the set {1, 2, · · · , 14} in which exactly 7 integers are in their natural positions is given by: \($$\binom{14}{7} \cdot D_7 = \binom{14}{7} \cdot 18144$$$$\frac{14!}{7!7!} \cdot 18144 = 6174448960$$\) Thus, there are 6,174,448,960 permutations of the set {1, 2, · · · , 14} in which exactly 7 integers are in their natural positions.
