The value of A in the triple integral ∫∫∫ Ƒ dV = 14/15 is A = -15(14/15) / (16y+64y³/3).

To find the value of A in the triple integral ∫∫∫ Ƒ dV, where the limits of integration are given, and the result is equal to 14/15, we need to evaluate the integral and solve for A.

Let's compute the given triple integral step by step. We have ∫∫∫ Ƒ dV = ∫[0 to 4] ∫[0 to x] ∫[0 to -x-y²] Adzdxdy. Integrating with respect to z first, we obtain ∫[0 to 4] ∫[0 to x] -A(x+y²) dydx. Integrating with respect to y, we have ∫[0 to 4] [-A(xy+y³/3)] dx. Finally, integrating with respect to x gives [-A(x²y+xy³/3)] evaluated from 0 to 4.

Evaluating the upper limit, we get [-A(16y+64y³/3)]. Plugging in the lower limit, we have [-A(0+0)] = 0. Thus, the result of the triple integral is [-A(16y+64y³/3)]. Setting the result equal to 14/15, we have [-A(16y+64y³/3)] = 14/15. Rearranging the equation, we get -A(16y+64y³/3) = 14/15.

To solve for A, we divide both sides of the equation by (-16y-64y³/3), resulting in A = -15(14/15) / (16y+64y³/3). Therefore, the value of A in the triple integral ∫∫∫ Ƒ dV = 14/15 is A = -15(14/15) / (16y+64y³/3).

answer = Volume of rectangular prism box / volume of cube

Step-by-step explanation:

To determine the number of Dice that will fit in the rectangular prism box

First : calculate the volume of the cube box ( dice )

volume of a Cube box : V = L^3       where L = side length  

next : calculate the volume of the rectangular prism box

volume of rectangular prism box = L * b * h

L= length , b = width , h = height

final step : Divide the volume of the rectangular prism box by the volume of the cube box ( dice )

= ( L * b * h ) / ( L^3 )

Answer: \(1\dfrac13\) hours

Step-by-step explanation:

Lily's goal to walk =  6 miles

Lily has walked 2 miles.

Let h= number of hours it will take Lily to reach her goal.

She walk 3 miles an hour.

Total miles she can walk in h hour = 3h

According to the question,

\(3h +2 = 6\)   (Required equation)

Subtract 2 from both sides , we get

\(3h = 4\)

Divide both sides by 3 , we get

\(h=\dfrac43=1\dfrac{1}{3}\)

Hence, it will take \(1\dfrac13\) hours to reach her goal.

The equation to find the number of hours it will take Lily to reach her goal is (2 + 3h = 6) and this can be determined by using the given data.

Given :

The following steps can be used in order to determine the equation to find the number of hours it will take Lily to reach her goal:

Step 1 - The linear equation can be formed in order to determine the number of hours it will take Lily to reach her goal.

Step 2 - Let the number of hours be 'h'.

Step 3 - So, the linear equation that represents the given situation is given below:

2 + 3h = 6

Step 4 - Simplify the above equation in order to determine the value of 'h'.

3h = 4

h = 4/3 hours

Answer: C. 72

Step-by-step explanation:

The set is:

{R, E, L, O, A, D}

if we separate it into consonants and vowels, we have

consonants: {R, L, D}

vowels : {E, O, A}

Now, we want combinations of 3 consonants and one vowel.

we have 4-letters combinations, let's fixate the first letter as the vowel,

for this first letter, we have 3 options {E, O, A}

for the second letter, a consonant, we also have 3 options  {R, L, D}

for the third letter, we also need to choose a consonant, but now we have 2 options (because we already selected one)

for the fourth letter, we have only one option.

Now, the total number of combinations is equal to the product of the number of options in each selection:

C = 3*3*2*1 = 18

But remember that this is the case where the vowel is fixed for the first letter, we have 4 positions where the vowel can be (first, second, etc)

So the actual number of combinations is:

C*4 = 18*4 = 72

The correct option is C.

Answer:

1. 3 cookies

2. 2 cups

3. 300 calories

4. $35 per month

5. k = y/x

6. If there is no constant (k)

Step-by-step explanation:

1. The number of cookies the factory makes in one minute = (The number of cookies the factory makes in 12 minutes)/(12 minutes)

∴ The number of cookies the factory makes in one minute = 36 cookies/(12 minutes) = 3 cookies/minute

The correct answer is 3 cookies

2. The number of cups of water that leak every minute = (The number of cups of water that leak in 1/4 minute) × (The number of 1/4 minute per minute)

The number of cups of water that leak every minute = 1/2 cup per 1/4 minute × 4_1/4 minute per minute

The number of cups of water that leak every minute = 1/2  × 4 = 2

The number of cups of water that leak every minute = 2 cups

3. 5 glazed donuts contains 750 calories

∴ 1 glazed donuts contains 750/5 = 150 calories

2 = 2 × 1 glazed donuts will contain 2 × 150 = 300 calories

4. The charge of the cell phone company for 2 months = $70

The charge of the cell phone company for 6 months = $210

The constant rate per month = The rate of change of the cell phones companys charges

∴ The constant rate per month = (210 - 70)/(6 - 2) = 140/4 = 35

The constant rate (per month) for the service = $35 per month

5. The formula to find the constant of a chart, k = y/x

6. A chart is not considered proportional if there is no constant (k)

The evidence from the test does not support the claim that the medicine is 80% effective in stopping the growth of skin cancer on rats.

Null hypothesis (H0): The medicine is not effective, and the true proportion of rats with the cancerous growth stopped is equal to or less than 80%.

Alternative hypothesis (Ha): The medicine is effective, and the true proportion of rats with the cancerous growth stopped is greater than 80%.

Given:

Sample size is 400 and 310 rats had their cancerous growth stopped.

We will calculate the sample proportion (p) of rats with the growth stopped:

p = 310/400

= 0.775

To perform the hypothesis test, we are using test statistic formula: z = (p - p) / √(p(1-p)/n)

Data:

p = 0.80 =  (80%)

n = 400.

z = (0.775 - 0.80) / √(0.80*(1-0.80) / 400)

= -0.025 / √(0.16/400)

= -0.025 / √0.0004

= -0.025 / 0.02

= -1.25

Using a significance level (α) of 0.05, we will compare the test statistic to the critical value from the standard normal distribution. The critical value for a one-tailed test at α = 0.05 is 1.645.

Since -1.25 < 1.645, we do not have enough evidence to reject the null hypothesis.

The value of x, the exterior angle, is 44°.

Given is a triangle ABC with two opposite interior angles 14° and 30° we need to find the value of x which is the exterior angles,

The sum of the measures of the interior angles of a triangle is always 180 degrees.

Since you have two opposite interior angles given, which are 14° and 30°, you can find the third interior angle by subtracting the sum of these two angles from 180°:

180° - (14° + 30°) = 136°

Now, let's consider the exterior angle, which is supplementary to the interior angle.

The sum of an interior angle and its corresponding exterior angle is always 180 degrees.

Therefore, the value of the exterior angle, x, can be found by subtracting the corresponding interior angle from 180°:

x = 180° - 136° = 44°

So, the value of x, the exterior angle, is 44°.

#SPJ1

Answer:

Step-by-step explanation:

The second theorem states that the exterior angle is equal to the sum of the two interior angles that are not adjacent to it. This second theorem is particularly important because it allows us to prove that the sum of the interior angles of a triangle is a straight angle.

so

Angle x = 30 + 14 = 44°

The angle x in the diagram is 98 degrees.

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angle, alternate exterior angles, vertically opposite angles, same side interior angles etc.

Therefore, let's find the angle of x using the angle relationships as follows:

The size of the angle x can be found as follows:

82 + x = 180(same side interior angles)

Same side interior angles are supplementary.

Hence,

82 + x = 180

x = 180 - 82

x = 98 degrees

Therefore, the answer is option B.

The correct answer is option D. Above the mean by a distance equal to 1.20 standard deviations .What is z-score? A z-score is also known as the standard score and is used to calculate the probability of a score occurring within a normal distribution's distribution.

It is a measure of how many standard deviations a data point is from the mean. It is denoted by the letter “Z.”Z-score calculation formula isz = (x- μ) / σ Where,

x = Score

μ = Mean

σ = Standard deviation

In this question, the z-score given is 1.20, which means it is 1.20 standard deviations above the mean. Therefore, option D. Above the mean by a distance equal to 1.20 standard deviations is the correct answer to the given question.

A z-score is the number of standard deviations that a data point is from the mean of a distribution. To solve this problem, we'll first need to determine the position in the distribution that corresponds to a z-score of 1.20. The formula for calculating z-score is z = (x - μ) / σwhere z is the z-score, x is the raw score, μ is the mean, and σ is the standard deviation. Using this formula, we can solve for the raw score that corresponds to a z-score of 1.20. We know that the z-score is 1.20, so we can substitute that value in for z:1.20 = (x - μ) / σWe also know that the mean is 0 (since z-scores are calculated based on a standard normal distribution with a mean of 0 and a standard deviation of 1), so we can substitute that value in for μ:1.20 = (x - 0) / σSimplifying the equation,

we get: 1.20σ = x Now we know that the raw score is equal to 1.20 standard deviations above the mean. So the correct answer is D. Above the mean by a distance equal to 1.20 standard deviations.

The probability that a rental car will be stolen is 0.0004, hence, for 3500 cars, the mean is:

\(\mu = 3500 \times 0.0004 = 1.4\)

The probability that 2 or fewer cars will be stolen is:

\(P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)\)

In which:

\(P(X = x) = \frac{e^{-\mu}\mu^{x}}{(x)!}\)

\(P(X = 0) = \frac{e^{-1.4}1.4^{0}}{(0)!} = 0.2466\)

ΔABC

A(-3, -1), B(0, 3), C(1, 2)

Find

the length of the perimeter of ΔABC to the nearest tenth

Solution

The perimeter of a triangle is the sum of the lengths of its sides. The length of each side can be found using the Pythagorean theorem. Effectively, each pair of points is treated as the end-points of the hypotenuse of a right triangle with legs parallel to the x- and y-axes. The leg lengths are the differences betweeen the x- and y- coordinates of the points.

The difference of the x-coordinates of segment AB are 0-(-3) = 3. The y-coordinate difference is 3-(-1) = 4. So, the leg lengths of the right triangle whose hypotenuse is segment AB are 3 and 4. The Pythagorean theorem tells us

... AB² = 3² +4² = 9 +16 = 25

... AB = √25 = 5

You may recognize this as the 3-4-5 triangle often introduced as one of the first ones you play with when you learn the Pythagorean theorem.

LIkewise, segment AC has coordinate differences of ...

... C - A = (1, 2) -(-3, -1) = (4, 3)

These are the same leg lengths (in the other order) as for segment AB, so its length is also 5.

Segment BC has coordinate differences ...

... C - B = (1, 2) -(0, 3) = (1, -1)

The length of the line segment is figured as the root of the sum of squares, even though one of the coordinate differences is negative. The leg lengths of the right triangle used for finding the length of BC are the absolute value of these differences, or 1 and 1. Then the length BC is

... BC = √(1² +1²) = √2 ≈ 1.4

So the perimeter of the triangle ABC is

... AB + BC + AC = 5 + 1.4 + 5 = 11.4 . . . . perimeter of ∆ABC in units

The present value of a 10 year bond with a face value of AUD 100 and annual coupons of AUD 10, when the market yield (yield to maturity) is 11% is AUD 94.11.

Calculate the present value of the annual coupon payments. The present value of a perpetuity is equal to the periodic payment (in this case, AUD 10) divided by the discount rate (in this case, 0.11)P = C / r

P = AUD 10 / 0.11

P = AUD 90.91

Calculate the present value of the face value. The present value of the face value is equal to the face value (in this case, AUD 100) divided by (1 + the discount rate raised to the number of periods remaining (in this case, 10)). P = F / (1 + r)n

P = AUD 100 / (1 + 0.11)10

P = AUD 38.65

Add the present value of the annual coupon payments and the present value of the face value to get the present value of the bond. Present Value of Bond = Present Value of Coupons + Present Value of Face Value Present Value of Bond = AUD 90.91 + AUD 38.65Present Value of Bond = AUD 129.56

Present Value of Bond = Present Value of Coupons + Present Value of Face Value Present Value of Bond = AUD 90.91 + AUD 38.65 Present Value of Bond = AUD 129.56

Therefore, the present value of the bond is AUD 129.56 or AUD 94.11 after rounding to two decimal places.
