The speed of the boat is approximately 9.21 km/h.

In order to ascertain the speed of the boat, we must find out the number of kilometers traversed by it and the amount of time taken for traveling that distance.

The traveled distance by the boat is equal to the space between two points,

or the magnitude of (final position vector - initial position vector),

which in this case is (-7i - 3j). Hence, the total distance of sqrt((-7)^2 + (-3)^2) kilometers is obtained.

Regarding the amount of time taken to travel that predetermined distance, it computes to be 2 hours 45 minutes, or 2.75 hours.

Therefore, through simple division, the speed of the boat can be determined at roughly 9.21 km/h, which results when you divide the traveled distance of sqrt(58) by the time taken in hours, that is, 2.75.

Answer:

To determine the density of the mixture, we need to first find the total volume of the mixture, which can be calculated by adding the volumes of metal A and metal B.

The volume of metal A can be calculated using the formula:

Volume = Mass / Density

So, the volume of metal A is:

Volume of A = 3.3g / 2.7g/cm³ = 1.2222... cm³ (rounded to four decimal places)

Similarly, the volume of metal B is:

Volume of B = 2.4g / 4.8g/cm³ = 0.5 cm³

The total volume of the mixture is therefore:

Total Volume = Volume of A + Volume of B

= 1.2222... cm³ + 0.5 cm³

= 1.7222... cm³ (rounded to four decimal places)

To find the density of the mixture, we can use the formula:

Density = Mass / Volume

The total mass of the mixture is:

Total Mass = Mass of A + Mass of B

= 3.3g + 2.4g

= 5.7g

So, the density of the mixture is:

Density = Total Mass / Total Volume

= 5.7g / 1.7222... cm³

= 3.3103... g/cm³ (rounded to four decimal places)

Therefore, the density of the mixture is approximately 3.3103 g/cm³

The probability of getting a large or blueberry smoothie is 7/15.

The probability is calculated based on the following assumptions:

Probability of getting a large smoothie = 1/3

Probability of getting a blueberry smoothie = 1/5

P(large and blueberry) = P(large) * P(blueberry)

P(large and blueberry) = (1/3) * (1/5)

P(large and blueberry) = 1/15

P(large or blueberry) = P(large) + P(blueberry) - P(large and blueberry)

P(large or blueberry) = 1/3 + 1/5 - 1/15

Given the following vectors:

[tex]\vec u =-5 \hat i +8 \hat j\\\vec v =56 \hat i +35 \hat j\\[/tex]

We are asked to determine whether vectors u and v are parallel or perpendicular.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

How do we do this?

To determine whether two vectors are parallel, the result of their cross product is zero.

To determine whether two vectors are perpendicular, the result of their dot product is zero.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

[tex]\bold{Given \ two \ vectors...}\\\vec a=a_x \hat i + a_y \hat j +a_z \hat k\\\\\vec b=b_x \hat i + b_y \hat j +b_z \hat k\\[/tex]

[tex]\bold{Cross \ Product} \Rightarrow \vec a \times \vec b= \begin{vmatrix}\hat i & \hat j & \hat k\\a_x & a_y & a_z\\b_x & b_y & b_z\end{vmatrix} \rightarrow \begin{vmatrix}a_y & a_z \\b_y & b_z \end{vmatrix} \hat i- \begin{vmatrix}a_x & a_z \\b_x & b_z \end{vmatrix} \hat j+\begin{vmatrix}a_x & a_y \\b_x & b_y \end{vmatrix} \hat k[/tex]

[tex]\bold{Dot \ Product} \Rightarrow \vec a \cdot \vec b = a_xb_x+a_yb_y+a_zb_z[/tex]

Note: The result of the cross product is a vector while the result of a dot product is a scalar.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Cross product:

[tex]\vec u \times \vec v = \begin{vmatrix}\hat i & \hat j & \hat k\\-5 & 8 & 0\\56 & 35 & 0\end{vmatrix}[/tex]

[tex]\Longrightarrow \begin{vmatrix} 8 & 0 \\ 35 & 0 \end{vmatrix} \hat i- \begin{vmatrix}-5 & 0 \\56 & 0 \end{vmatrix} \hat j+\begin{vmatrix}-5 & 8 \\56 & 35 \end{vmatrix} \hat k[/tex]

[tex]\Longrightarrow [(8)(0)-(0)(35)]\hat i -[(-5)(0)-(0)(56)]\hat j +[(-5)(35)-(8)(56)] \hat k[/tex]

[tex]\Longrightarrow (0)\hat i (0)\hat j +[-175-448] \hat k[/tex]

[tex]\Longrightarrow (0)\hat i (0)\hat j +(-623) \hat k[/tex]

[tex]Thus, \ \boxed{\vec u \times \vec v = 0\hat i + 0\hat j -623 \hat k}[/tex]

Which does not equal zero. So, these vectors aren't parallel.

Now, dot product:

[tex]\vec u \cdot \vec v = (-5)(56)+(8)(35)+(0)(0)[/tex]

[tex]\Longrightarrow \vec u \cdot \vec v = -280+280+0[/tex]

[tex]Thus, \ \boxed{ \vec u \cdot \vec v = 0}[/tex]

The dot product of vectors u and v equals zero. These vectors are perpendicular!

The point estimator of the mean percentage of airline reservations canceled on the day of the flight is the midpoint of the 95% confidence interval, which is (3% + 9%) / 2 = 6%.

The point estimator of the mean percentage of airline reservations being canceled on the day of the flight is the midpoint of the confidence interval, which is (3% + 9%) / 2 = 6%. Therefore, the point estimator of the mean percentage of reservations that are canceled on the day of the flight is 6%.

This means that based on the data, we can estimate that the mean percentage of airline reservations being canceled on the day of the flight is around 6%. However, since this is a point estimate, there is some uncertainty associated with it. The 95% confidence interval provides a range of values within which we can be 95% confident that the true mean percentage of cancellations falls. In this case, we can be 95% confident that the true mean percentage of cancellations on the day of the flight falls between 3% and 9%.

Overall, the interval and the point estimator provide us with useful information about the mean percentage of airline reservations being canceled on the day of the flight and allow us to make informed decisions and predictions about future cancellations.

we have given that 3 consucetive sum are 18 so we write this equetion as

x + x + 1 + x + 2 = 18

3x + 3 = 18

3x = 18 - 3

3x = 15

3x/3 = 15/3

x = 5

Using the definite integral, it is determined that the driver is 108 miles from his home at 1:00 PM.

We need to find the distance travelled by the driver between 11:00 AM and 1:00 PM.

The velocity of the driver is given by v(t) = 54t − 24t^2.

We can find the distance travelled by finding the definite integral of v(t) with respect to t, between 0 and 2 (since the driver leaves at 11:00 AM and we need to find the distance travelled by 1:00 PM, which is 2 hours later).

[tex]\int\limits^0_2[/tex]v(t) dt   =    [tex]\int\limits^0_2[/tex](54t − 24t²) dt

= [27t² - 8t³] between 0 and 2

= [27(2)² - 8(2)³] - [27(0)² - 8(0)³]

= 108 - 0

Answer: To determine the probability that there exists a triangle with side lengths x, y, and z, we need to find the probability that the three side lengths satisfy the triangle inequality, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

Since x, y, and z are independent and uniformly distributed on [0, 1], the probability density function of each variable is f(t) = 1 for 0 ≤ t ≤ 1 and 0 otherwise.

We can use geometric probability to determine the probability that x, y, and z satisfy the triangle inequality. Imagine a cube with side length 1, where the x-axis represents the value of x, the y-axis represents the value of y, and the z-axis represents the value of z. The region of the cube where x + y > z, x + z > y, and y + z > x corresponds to a tetrahedron with vertices at (0, 0, 0), (1, 0, 0), (0, 1, 0), and (0, 0, 1), as shown below:

    (0,1,0)         (1,0,0)

       *---------------*

      /|              /|

     / |             / |

    /  |            /  |

(0,0,1)  *----------/---* (1,0,1)

   |   / (0,0,0)  |   /

   | /            | /

   |/             |/

   *---------------* (0,1,1)

  (0,1,1)        (1,1,0)

The volume of this tetrahedron is 1/6 of the volume of the cube, since each of the four triangular faces has half the area of a face of the cube.

Therefore, the probability that x, y, and z satisfy the triangle inequality (i.e., that there exists a triangle with side lengths x, y, and z) is equal to the volume of this tetrahedron, which is 1/6.

Hence, the probability that there exists a triangle with side lengths x, y, and z is 1/6, or approximately 0.1667.

The probability that there exists a triangle with side lengths x, y, and z is 1/6 or approximately 0.1667.  The probability that there exists a triangle with side lengths x, y, and z can be found by determining the probability that the three sides satisfy the triangle inequality.

This inequality states that the sum of any two sides must be greater than the third side.

Since x, y, and z are chosen uniformly from [0, 1], we can assume that they are continuous random variables with a uniform distribution over the interval [0, 1].

Therefore, the probability that the three sides satisfy the triangle inequality can be found by integrating the joint probability density function of x, y, and z over the region where the triangle inequality holds. This region can be described as the set of all (x, y, z) that satisfy the following three conditions:

1) x + y > z
2) x + z > y
3) y + z > x

To find the probability, we integrate the joint probability density function over this region:

P(triangle exists) = ∫∫∫ R f(x, y, z) dxdydz

where R is the region defined by the three conditions above, and f(x, y, z) is the joint probability density function of x, y, and z, which is 1 over the interval [0, 1] since they are uniformly distributed.

Evaluating this triple integral is a bit tricky, but it turns out that the probability is 1/6. Therefore, the probability that there exists a triangle with side lengths x, y, and z is 1/6, which is approximately 0.1667.

The biconditional statement p <-> q is true when p and q have the same truth values and is false otherwise.

Step-by-step explanation:

This is because the biconditional is saying "p if and only if q"

A biconditional statement, written as "p if and only if q" or "p <--> q," is only true when both p and q have the same truth value. In other words, if p is true, then q must also be true for the biconditional statement to be true. Likewise, if p is false, then q must also be false.

Therefore, a biconditional statement is only true when the two statements being compared have equivalent truth values. A biconditional statement, represented as p ↔ q, is only true when both p and q have the same truth values. In other words, it is true when:

1. p is true and q is true, or
2. p is false and q is false.

A biconditional essentially means "p if and only if q." If both statements are true or both statements are false, then the biconditional is true. If one statement is true and the other is false, then the biconditional is false.

A(full block)=LA+2B          P= 9+9+16+16=50    h=10     B=(9)(16)

= Ph+2B              P, perimeter of Base;   h, height    B, area of base

=(50)(10)+2(144)

=788 yd²

A(cut out) = LA +2B         P=13+13+4+4=34     h=10   B=(13)(4)=52

=Ph +2B

=34(10)+2(52)

=444 yd²

Now subtract the 2 areas and that will give you your shape

A(shape)=A(full block)-A(cut out)

A(shape)= 788-444=344 yd²

A confidence interval is a range of values that is likely to contain the true value of an unknown parameter with a certain level of confidence.

We can use the formula for the confidence interval of a proportion:

p±z α/2√p(1− p)/n

where $\hat{p}$ is the sample proportion, $n$ is the sample size, and $z_{\alpha/2}$ is the critical value from the standard normal distribution.

In this case, we have $\hat{p} = \frac{14}{130} = 0.1077$ and $n=130$. Using a table or calculator, we find that $z_{\alpha/2} = 2.33$ for a 98% confidence interval.

Plugging in the values, we get:

0.1077±2.33 √0.1077(1−0.1077)/130

Simplifying, we get:

(0.063,0.153)

So the answer is (A).
