Answer:

21°

Step-by-step explanation:

In an sosceles trapezoid, the lower base and upper base angles are congurent

⇒ ∠HGF = ∠EFG

⇒ 9y + 3 = 8y + 5

⇒ 9y - 8y = 5 - 3

⇒ y = 2

⇒ ∠HGF = 9(2) + 3

= 18 + 3

= 21

The measure of angle HGF in the given isosceles trapezoid EFGH is calculated to be 21 degrees.

This problem deals with the properties of an isosceles trapezoid, which is a type of quadrilateral. In an isosceles trapezoid, opposite angles are equal. In this case, angle EFG and angle HGF would be equal to each other given the shape is an isosceles trapezoid. So, their measures should be equal.

Here, the measure of angle HGF is given as (9y + 3)°, and the measure of angle EFG is (8y + 5)°. Setting these equal to each other to find the value of y, we get 9y + 3 = 8y + 5. By simplifying, we get the value of y is 2. Substituting the found value of y in angle HGF we get, 9*2+3 = 21 degrees.

The function is an exponential growth function

The function is given as

y=2(1.06)^9

We can begin by rewriting the given equation as:

y = 2 * 1.06t

So, we have

y = 2 * (1 + 0.06)^t

Now we can see that the equation is in the form y = a*b^t,

where a = 2 and b = 1.06^9

This equation represents exponential growth because the base of the exponent, b = 1.06, is greater than 1.

We can re-write it in the form y = a(1+r)t,

we can find the value of r by subtracting 1 from 1.06 which is 0.06 and the value of a is 2.

so we have y = 2(1+0.06)^t

So, the equation represents exponential growth with a = 2 and r = 0.06

The general form of the equation of a line in slope intercept is y = mx+b where m is the slope and b is the intercept. To find the equation, we simply need to find the values of m and b.

Have in mind that if we have two lines y = mx+b and y = dx+e, we say that two lines are perpendicular if the product of their slopes is -1. That is

We are given the line y = (3/2)x+(1/4). For this line, the slope is (3/2). Since we want that our line y =mx+b is perpendicular to the given line, it must happen that

If we multiply by 2 on both sides and then divide by 3, we get

So far, we have the equation of our line to be y = (-2/3)x+b. We are given that this line passes through the point (6,1). This means that in this equation, if we replace x by 6, then we get y=1. This leads to the equation

So, if we add 4 on both sides, we get

So the equation of our line is y = (-2/3)*x + 5.

Answer:

100000+45000+500+60+7

Answer:

correct answer is 456 sq units.

Step-by-step explanation:

Let us have a look at the formula for Surface Area of a prism:

\(A =p \times h+2 \times B\)

Where p is the perimeter of base

h is the height of prism

and B is the base area of prism.

Given that:

h = 7.5 units

Hypotenuse of prism's base = 20 units

One of the Other sides = 12  units

Pythagorean theorem can be used to find the 3rd side of right angled base.

Square of hypotenuse = Sum of squares of other two sides

\(20^2=12^2+side^2\\\Rightarrow 400=144+side^2\\\Rightarrow side =\sqrt{256}\\\Rightarrow side =16\ units\)

Area of base = area of right angled triangle:

\(B = \dfrac{1}{2} \times \text{Base Length} \times \text{Perpendicular Length}\\\Rightarrow B = \dfrac{1}{2} \times 16\times 12 = 96\ sq\ units\)

Perimeter \(\times\) height = (12+20+16) \(\times\) 7.5 = (48) \(\times\) 7.5 = 360 sq units

Now putting the values in formula:

Surface area, A = 360+96 = 456 sq units

So, correct answer is 456 sq units.

Unbiased estimators are statistical estimators that give an estimate of a population parameter that is equal to the true population parameter on average, regardless of the sample size.

The analysis suggests that the process Î 3 is more efficient than Î 1 and Î 2 when considered separately. However, when combined, the processes Î 1/2 and Î 2/2 are less efficient.

(a) To find out if Î 3=Î 1+Î 22 is unbiased, we must compute its anticipated value and contrast it with Î.

If Î 1 and Î 2 are unrelated and unbiased, E(Î 3) = E(Î 1 + Î 22) = E(Î 1) + E(Î 22) = Î + Î = 2Î

E(Î3) is biased as it does not equal Î.

(b) The formula for the variance of a linear combination of random variables can be used to assess if Î3 is more effective than Î1 and Î2.

Var(Î 3) is equal to Var(Î 1) plus 2Cov(Î 1, Î 2) plus Var(Î 2)/4.

Var(Î 1) = Var(Î 2) and Cov(Î 1, Î 2) = 0 result in:

Var(^θ3) = 5/4

Var(^θ1)

Var(Î 1) > 4/5Var(Î ), meaning that Î 3 is more effective than Î 1 and Î 2. If not, Î1 is more effective.

(c) If Var(Î1|Î2|Î3] Var(Î1|Î3]), then Î2 is more effective than Î1. Assume that Î1 and Î2 are equal and that Var(Î1) Var(Î2) independent. To calculate the variance of Î3, we can use the following formula for the variance of a linear combination of random variables:

As Î1 and Î2 are independent, Var(Î 3) = Var(Î 1) + 2Cov(Î1, Î2) + Var(Î2)/4 = Var(Î1) + 0 + Var(Î2)/4.

Var(Î 1) + Var(Î 2) = 4 and (Var(Î 1) + Var(Î 2)) = 2

As a result, Ï 3 is more effective than Î 1 and Î 2 taken separately, but not as effective as Î 2/2 and Î 1/2 taken together.

The loss percentage is 91%.Given that Venessa bought 80 apples for 4$, out of these apples, 25% were rotten and had to be thrown away. Venessa sold the remaining apples at 6 cents per apple.To calculate the profit or loss percentage, we need to determine the cost price, selling price, and the number of apples sold.

Cost price (CP) = 4 $.Selling price (SP) = 80 × 0.75 × 6 cents= 36 cents = 0.36 $.Now, let's calculate the profit.Profit = SP – CP= 0.36 $ – 4 $= – 3.64 $Loss = CP – SP= 4 $ – 0.36 $= 3.64 $.

Therefore, Venessa incurred a loss of $3.64 when she sold 80 apples at 6 cents per apple.Now let's calculate the loss percentage Loss Percentage = (Loss / CP) × 100= (3.64 / 4) × 100= 91%.

The same variable word is frequently used in mathematical formulas to attempt to ensure consistency between two assertions. Mathematical equations, also referred to as assertions, are used to demonstrate the equality of many academic figures. Instead of dividing 12 into two portions in this instance, the normalise function adds b + 6 to use the illustration of

y + 6.

Here,

Part 1: We will add 1 to both sides of the equation because we want to separate n in this situation:

=> n - 1 + 1 = 2 + 1

Simplifying:

=> n = 3

Consequently, n = 3 is the answer to the problem n - 1 = 2 when n is taken into account.

To put it up:

=> n - 1 = 2

To both ends, add one:

=> n - 1 + 1 = 2 + 1

Simplify:

=>n = 3

Part 2:

In order to isolate the variable (n) on one side of the equation, we can use inverse operations to answer for n in the equation n - 1 = 2.

Addition is the opposite of reduction. In order to isolate n in this example, we therefore add 1 to both sides of the equation using the inverse process of subtraction.

The steps required are as follows:

=>  n - 1 = 2 (original calculation) (original equation)

To both ends, add one:

=>  n - 1 + 1 = 2 + 1

Answer: f(n) = 2n - 2

Therefore, we can use this formula to find the value of f(n) for any positive integer n.

Step-by-step explanation: Using the given recursive formula:

f(1) = 0

f(n) = f(n-1) + 2

We can find the values of f(n) for different values of n:

f(1) = 0

f(2) = f(1) + 2 = 0 + 2 = 2

f(3) = f(2) + 2 = 2 + 2 = 4

f(4) = f(3) + 2 = 4 + 2 = 6

f(5) = f(4) + 2 = 6 + 2 = 8

And so on.

We can see that each term in the sequence is 2 more than the previous term. So, we can write the general formula for f(n) as:

f(n) = 2n - 2

Therefore, we can use this formula to find the value of f(n) for any positive integer n.

A common denominator is a shared multiple of the denominators of the fractions involved when adding or subtracting fractions. It enables fraction comparison and addition/subtraction.

Simplification is the process of reducing a fraction to its simplest form by dividing the numerator and denominator by their greatest common divisor. This is done to represent fractions in the simplest terms viable.

Conversion: The process of transferring a fraction from one form to another while retaining its equal value is known as conversion. Finding a common denominator or expressing a fraction in terms of a specified unit or fraction may be required.

Fraction Addition/Subtraction: When adding or subtracting fractions, a common denominator is required. This entails determining a common multiple of

To rewrite the expression 3 + 1/5 + 2/3 using fifteenths as the common denominator, we need to find a common denominator for 5 and 3, which is 15 (since 5 and 3 are both factors of 15).

First, let's convert the fractions 1/5 and 2/3 to fifteenths:

\((\frac{1}{5})(\frac{3}{3}) = \frac{3}{15}\)
