18%
23%
29%
31%

Answers

Answer:

  (a)  18%

Step-by-step explanation:

The debt to credit ratio is found by dividing his debt by his credit limit.

  ratio = debt/credit limit = $1551.42/$8619.00 ≈ 0.18 = 18%

Quentin's debt to credit ratio is 18%.

Find the four second partial derivatives. Observe that the second mixed partials are equal. z=x^4 - 3xy + 9y^3. O ∂^2z/∂x^2 = ___. O ∂^2z/∂x∂y = ___. O ∂^2z/∂y^2 = ___. O ∂^2z/∂y∂x = ___.

Answers

The final answer is
O ∂^2z/∂x^2 = 12x^2
O ∂^2z/∂x∂y = ∂^2z/∂y∂x = -3
O ∂^2z/∂y^2 = 54y

To find the second partial derivatives, we first need to find the first partial derivatives:

∂z/∂x = 4x^3 - 3y
∂z/∂y = -3x + 27y^2

Now, we can find the second partial derivative:

∂^2z/∂x^2 = 12x^2
∂^2z/∂y^2 = 54y
∂^2z/∂x∂y = ∂/∂x (∂z/∂y) = ∂/∂y (∂z/∂x) =  -3
∂^2z/∂y∂x = ∂/∂y (∂z/∂x) = ∂/∂x (∂z/∂y) = -3

We can observe that the second mixed partials (∂^2z/∂x∂y and ∂^2z/∂y∂x) are equal, which is expected since z has continuous second partial derivatives and satisfies the conditions for the equality of mixed partials (i.e., the partial derivatives are all continuous in some open region containing the point of interest).

To insure a house valued at £3000 costs £2.25. Find the value of a house which costs £3.37 1/2 to insure.

Answers

Using the cross-multiplication method, we know that the house which costs £3.37  has a value of £4,493.33.

What is a cross-multiply method?One might cross-multiply an equation between two fractions or rational expressions in mathematics, more specifically in elementary arithmetic and elementary algebra, to make the equation simpler or to find the value of a variable.When using the cross-multiplication approach, the denominator of the first term is multiplied by the numerator of the second term and vice versa.

So, the value of the house costs £3.37:

House that costs £2.25 is valued at £3000.

Now, use the cross-multiplication method as follows:

2.25/3000 = 3.37/x2.25x = 3000 × 3.372.25x = 10,110x = 10,110/2.25x = 4,493.33

Therefore, using the cross-multiplication method, we know that the house which costs £3.37  has a value of £4,493.33.

Faizah is paid $11 per hour for her work at a factory. She works 9 hours a day and 24 days a month. She saves $594 a month. Express the amount she saves as a percentage of her income.​

Answers

Answer:

The amount she saves is 25% of her income

Step-by-step explanation:

She is paid $11 per hour

She works 9 hours per day

and for 24 days per month

So, she works 9(24) hours per month

= 216 hours per month

Now, she is paid $11 hourly, so for 216 hours,

she will have 11(216) = $2376

Total income = $2376 per month

Saving = $594 per month

As a percentage, we divide the savings by the total income,

savings/(total income) = 594/2376 = 1/4 = 0.25

Answers

The cost of renting the car of given function is 350$.

A special kind of function called an algebraic function is the answer to a polynomial equation with polynomial coefficients. Numerous hints about an algebraic function's characteristics can be found in its informal formulation. To gain an intuitive understanding, it may be helpful to regard algebraic functions as functions which can be formed by the usual algebraic operations: addition, multiplication, division, and taking an nth root.

The function is S(x)=110+60(x-1)=50+60x, for x=number of days total/partial, rounded up to the next integer.

Day 1 $110

Day 2 $110+60=$170

So S(4.5)=S(5)

S(4.5)=$110+$240=$350

Hence, the cost of renting the car is 350$

The proportion of a normal distribution located between z = .50 and z = -.50 is ____.

Answers

The proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.

We have,

A normal distribution located between z = 0.50 and z = -0.50,

So,

Now,

From the Z-score table,

We get,

The Probability corresponding to the Z score of -0.50,

i.e.

P(-0.50 < X < 0) = 0.191,

And,

The Probability corresponding to the Z score of -0.50,

i.e.

P(0 < X < 0.50) = 0.191,

Now,

The proportion of a normal distribution,

i.e.

P(Z₁ < X < Z₂) = P(Z₁ < X < 0) + P(0 < X < Z₂)

Now,

Putting values,

i.e.

P(-0.50 < X < 0.50) = P(-0.50 < X < 0) + P(0 < X < 0.50)

Now,

Again putting values,

We get,

P(-0.50 < X < 0.50) = 0.191 + 0.191

On solving we get,

P(-0.50 < X < 0.50) = 0.382

So,

We can write as,

P(-0.50 < X < 0.50) = 38.2%

So,

The proportion of a normal distribution is 38.2%.

Hence we can say that the proportion of a normal distribution located between z = .50 and z = -.50 will be 38.2%.

how many bit strings of length seven either begin with two 0s or end with three 1s?

Answers

There are 40 such bit strings.

To count the number of bit strings of length seven that either begin with two 0s or end with three 1s, we need to use the principle of inclusion-exclusion.

Let A be the set of bit strings that begin with two 0s, and let B be the set of bit strings that end with three 1s.

Then, we want to find the size of the set A ∪ B, which consists of bit strings that satisfy either condition.

The size of A can be calculated as follows:

since the first two digits must be 0, the remaining five digits can be any combination of 0s and 1s,

so there are \(2^5 = 32\) possible strings that begin with two 0s.

Similarly, the size of B can be calculated as follows:

since the last three digits must be 1, the first four digits can be any combination of 0s and 1s,

so there are\(2^4 = 16\) possible strings that end with three 1s.

However, we have counted the strings that both begin with two 0s and end with three 1s twice.

To correct for this, we need to subtract the number of strings that belong to both A and B from the total count.

The strings that belong to both A and B must begin with two 0s and end with three 1s, so they have the form 00111xxx,

where the x's can be any combination of 0s and 1s.

There are \(2^3 = 8\) such strings.

Therefore, the total number of bit strings of length seven that either begin with two 0s or end with three 1s is:

|A ∪ B| = |A| + |B| - |A ∩ B| = 32 + 16 - 8 = 40.

halfway through the fourth year , harrys collection contains 400 pennies. study the graph provided at the beginning of this activity. find the point that represents his progress. what are the coordinates of the points

Answers

Answer:

The coordinates of the point is (3,5 , 400)

Step-by-step explanation:

The question is incomplete as the graph is not given in the question. Lets complete the question first. I have attached the graph related to this question below.

We can see in the graph that x-axis represents the years while the y-axis represents the pennies collected by Harry.

We have to find the coordinates of the point where he is able to collect 400 pennies.

As y-axis represents pennies, and the point to be found is at 400 pennies, so the y-coordinates of the point is 400.

Harry collects 400 pennies when he is halfway through 4rth year, which means that he has been collecting for:

3 years + Half of 4rth year = 3.5 years.

As x-axis represents the year and the point to be found is at 3.5 years, so the x-coordinate of the point is 3.5.

So, the coordinates of the point is (3,5 , 400)

This point can be seen in the second graph

2/3g = 3 13/24 + 156

2/3g = 159 17/24

a sack contains n unbiased coins. among them, n-1 coins are normal (i.e., head on one side andtail on the other side), and one coin is fake, having heads on both sides. you pick a coin,uniformly at random, from the sack and flip it twice. you get heads both times. what is theconditional probability that you picked the fake coin?

Answers

The conditional probability that you picked the fake coin given that you got heads twice is 4/(3n-1).

Let E be the case where you choose the bogus coin and F be the case where you got heads twice. We wish to calculate P(E|F), which is the likelihood that you chose the fake coin given that you received heads twice.

By Bayes' theorem, we have:

P(E|F) = P(F|E)P(E) / P(F)

We can calculate each term on the right-hand side as follows:

P(F|E) = 1, Because the fake coin contains heads on both sides and always results in two heads when flipped.

P(E) = 1/n, since there is only one fake coin among n coins.

P(F) = P(F|E)P(E) + P(F|not E)P(not E), where not E is the event that you picked a normal coin. We can calculate:

P(F|not E) = (n-1) * (1/2)^2 = (n-1)/4, Because each normal coin has a 50% chance of revealing heads on each given flip and there are n-1 normal coins

P(not E) = (n-1)/n, since there are n-1 normal coins among n coins.

Therefore, we have:

P(F) = 1 * (1/n) + (n-1)/4 * (n-1)/n = (3n-1)/(4n)

Substituting these values into Bayes' theorem, we get:

P(E|F) = 1 * (1/n) / ((3n-1)/(4n)) = 4/(3n-1)

Thus, the conditional probability that you picked the fake coin given that you got heads twice is 4/(3n-1).

what is unitary method ?

Finding the worth of one unit of a quantity, then using this value to determine the value of a specified number of units of the quantity, is known as the unitary technique. When solving issues involving rates, ratios, and proportions, this approach is helpful. The fundamental tenet of the unitary technique is that we can use the value of one unit of a quantity to determine the value of any number of additional units of the same quantity.

given

Let's symbolise the cost of a cup of apple juice by the variable x.

So, a cup of lemon juice is sold for 3/2 times x, or (3/2)x.

Mr. Tan offers 5 cups of apple juice for every 2 cups of lemon juice. This indicates that there are 2.5 sales of lemon juice for every 1 sales of apple juice.

Assume Mr. Tan sells 5y cups of apple juice and 2y cups of lemon juice.

Based on the information provided, we can conclude that apple juice generates $12 more revenue than lemon juice.

in order to create an equation:

5yx = 2(3/2)x + 12

Simplifying:

5yx = 3x + 12

adding two to both sides:

10yx = 6x + 24

x(10y - 3) = 12

x = 12 / (10y - 3) (10y - 3)

We can now re-use this number of x to represent the revenue from apple juice in the equation:

5yx = 3x + 12

5y(12 / (10y - 3)) = 3(12 / (10y - 3)) + 12

Therefore, Mr. Tan charges $1/7 for each cup of apple juice and (3/2)($1/7) Equals $3/14 for each cup of lemon juice.

He charges (5/7)($1/7) = $5/49 for 5y = 5(1/7) = 5/7 glasses of apple juice.

For a sum of (2/7)($3/14) = $3/49, he sells 2y = 2(1/7) = 2/7 cups of lemon juice.

For each 7 cups of juice sold, Mr. Tan makes a sum of $5/49 + $3/49 = $8/49.

Consider that he offers 2n cups of lemon juice and 5n glasses of apple juice. (2n)($3/14) + (5n)($1/7) = $6n/49 + $5n/49 = $11n/49

He makes $8/49 for every 7 cups of juice sold, so his overall profits will be some multiple of $8/49.
