Question one

Answers

By using the concept of differentiation, it can be calculated that

value of P is -2 and value of Q is 1

What is differentiation?

Differentiation is the process where  the instantaneous rate of change of function can be calculated based on one variable. Differentiation is a very important tool in calculus

Here differentiation is used

f(x) = [tex]x^2y[/tex]

[tex]df = 2xydx+x^2dy[/tex]

Here P = 2xy, Q = [tex]x^2[/tex]

At x = 1, y = -1

P = 2(1)(-1) = -2

Q = [tex](-1)^2[/tex] = 1

So value of P is -2 and value of Q is 1

Answers

The value of ∠FED is 120° and ∠CBD is complementary to ∠FDE

What are complementary angles?

Complementary angles are two angles that sum up to 90°

For example 60° and 30° are complementary.

Either angle is called the complement of the other angle.

∠FED, ∠FDE and ∠DFE are in a triangle.

so,

∠FED + ∠FDE  +  ∠DFE = 180°

16x - 8 + 2x + 9 + 35 = 180 ( sum of angles in a triangle)

18x +36 = 180

18x = 180 - 36

18x = 144

x = 144/18

x = 8

so ∠FED = 16x - 8

Substitute x = 8 into the equation above we have

16(8) - 8 = 128 - 8 = 120°

∠FDE = 2x + 9

∠FDE = 2(8) + 9 = 25°

∠BED = 6x + 12

∠BED = 6(8) + 12

∠BED = 48 + 12

∠BED = 60°

∠CBD = -2x + 81

∠CBD = -2(8) + 81

∠CBD = 65°

so since ∠CBD = 65° and 90 - 65 = 25°

∠CBD is complementary to ∠FDE

In conclusion, ∠FED is 120° and ∠CBD is complementary to ∠FDE

Lena took out a $9000 loan for 7 months and was charged simple interest. The total interest she paid on the loan was $336.

Answers

The loan given has a rate of 0.53%

Simple Interest

Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time. In simple interest, the principal amount is always the same, unlike compound interest where we add the interest of previous years principal to calculate the interest of the next year.

The formula of simple interest is given as;

S.I = P(1 + RT)

S.I = Simple interestP = principalR = rateT = time

Substituting the values into the formula;

(9000 + 336) = 9000(1 + r * 7)

9336 = 9000 + 63000r

Collecting like terms

336 = 63000r

r = 0.0053

r = 0.0053 * 100

r = 0.53%

The standard deviation of the sampling distribution is 0.01767.

What is a standard deviation?

Standard deviation is a measure of the amount of variability or spreads in a set of data.

It is calculated as the square root of the variance and is often denoted by the symbol σ (sigma) for a population and s for a sample.

We have,

Given that the sample size is sufficiently large (n=400) and the population proportion is known, we can use the formula for the standard deviation of the sampling distribution of the sample proportion, which is:

[tex]\sigma_{\hat{p}} = \sqrt((p (1 - p)) / n)[/tex]

where p is the population proportion and n is the sample size.

In this case,

p = 0.53 (as given in the problem) and n = 400.

Substituting these values into the formula, we get:

[tex]\sigma_{\hat{p}} = \sqrt((0.53 (1 - 0.53)) / 400)\\\sigma_{\hat{p}} = \sqrt((0.53 0.47) / 400)\\\sigma_{\hat{p}} = \sqrt(0.0003121)\\\sigma_{\hat{p}} = 0.01767[/tex]

Given, The bag contains,

Number of gold marbles (P1)  = 3

Number of silver marbles (P2) = 5

Number of black marbles (P3) = 26

Also given,

The winning value if a gold marble is selected = $3

The winning value if a silver marble is selected = $2

The losing value if a black marble is selected = $1

Probability = Expected value/ Sum of the total number of events

Probability of picking a gold marble,

A family has two cars. During one particular week, the first car consumed 30 gallons of gas and the second consumed 40 gallons of gas. The two cars drove a combined total of 1600 miles, and the sum of their fuel efficiencies was 45 miles per gallon. What were the fuel efficiencies of each of the cars that week?

Answers

If the fuel efficiencies of each of the cars that week is  20 gallons of gas and  25 gallons of gas.

How to find the efficiencies?

Let x represent the gallons consumed by car 1

Let y represent gallons consumed by car 2

Formulate an equation:

30x+40y = 1600      equation 1

x+y = 45                equation 2

Substituting equation  2 into equation 1,

30x+40(45-x) = 1600

30x+ 1800-40x = 1600

-10x+1800 = 1600

-10x = -200

Divide both side by -10x

x = -200/-10

  x = 20

Substitute value of x into equation 2

x+y = 45

20+y = 45

     y = 25

Hence,

Car 1 consumes 20 gallons of gas and Car 2 consumes 25 gallons of gas.

What are the points on the graph called?

These points are called Coordinates, where the horizontal line denotes the x-axis and the verticle line is the y-axis.

Each point is identified by both x and y coordinates. A point's x-coordinate is a value that indicates how far the point is from the horizontal or x-axis origin.

According to the given information:

y denotes the distance of the point on the vertical line from the origin

x denotes the distance of the point on the horizontal line from the origin

In the given equation y=-1/3x-1

We can substitute x with any integer (i.e any number among the positive or negative numbers)

Putting, x=1 in the given equation we get

y=-1/(3x1)-1

⇒ y=-1/3-1

⇒y=-1/2

Thus the coordinate when x=1 is (1,-1/2)

y=6x+1

Substitute 6x+1 for y in 7x−2y=−1:

7x−2(6x+1)=−1

−5x−2=−1 (Simplify both sides)

C) X → Z: If a shape has three sides, then the sum of the interior angles of the shape is 180°. D) X → Z: If the sum of the interior angles of a shape isn't 180°, then it doesn't have three sides.

The correct statement that is a combination of both conditional statements is;  X → Z: If the sum of the interior angles of a shape is 180°, then it has three sides.

How to interpret conditional statements?

A triangle is defined as a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees.

We are given the conditional statements as;

X → Y: If the sum of the interior angles of a shape is 180°, then it's a triangle.

Y → Z: If a shape is a triangle, then it has three sides.

Now, transitive property states that “if two quantities are equal to a third quantity, then we can say that all the quantities are equal to each other”.

Thus, applying transitive property to our given statements we can say that;  X → Z: If the sum of the interior angles of a shape is 180°, then it has three sides.

We are given the function; f(x) = x²

Also, we want to find the graph of g(x) = f(x)

From the above, it means that we put x in place of x for function f(x) to get the function g(x).
