The percent of the decrease in the size of the sugar order is 40%.

According to the question,

We have the following information:

Sweet Treats Bakery ordered 1,090 kilograms of sugar. This time, the bakery is ordering 654 kilograms.

We know that following formula is used to find the percent decrease:

100*(original amount-final amount)/original amount

(More to know: the same formula is used to find the percent increase. It can used to find any percent increase or decrease given that the final and initial amount or price is given.)

100(1090-654)/1090

100*436/1090

40%

Hence, the percent of the decrease in the size of the sugar order is 40%.

The functions f(x) = (2x - 3) / 2 and g(x) = (2x + 3) / 2 are the inverse functions because the composite of the given functions equal to x that is fog = x and gof = x.

The conditions for two functions f and g to be inverses: f(g(x)) = x or g(f(x)) = x.

where, f(g(x)) and g(f(x)) is the composite function.

We are given:

f(x) = (2x - 3) / 2

g(x) = (2x + 3) / 2

Let us find the value of f(g(x)) and g(f(x)):

Substitute the value of x with g(x) in f(x), we will get:

f(g(x)) = (2 * g(x) - 3) /2 = (2 * ((2x + 3) / 2) - 3) /2 = (2x + 3 - 3) / 2 = 2x / 2 = x

So, f(g(x)) = x.

Substitute the value of x with f(x) in g(x), we will get:

g(f(x)) = (2 * f(x) + 3) /2 = (2 * ((2x - 3) / 2) + 3) /2 = (2x - 3 + 3) / 2 = 2x / 2 = x

So, g(f(x)) = x.

Thus, the functions f(x) = (2x - 3) / 2 and g(x) = (2x + 3) / 2 are the inverse functions because the composite of the given functions equal to x that is fog = x and gof = x.

The mean of the data set is 22.1 , and the sample proportion of numbers less than the mean is 46.67 %

The mean is the average value which can be calculated by dividing the sum of observations by the number of observations

Mean = Sum of observations/the number of observations

Mean of the data set is calculated by adding all numbers and dividing it with total number sample data.

Then Adding all the numbers;

The amount of money that Lena needs to put each quarter for the annuity to have a total value of $96,000 is $953.45.

An annuity is when a series of payment is made either at the beginning of a period or at the end of a period over a period of time.

An ordinary annuity is when the payment is made at the end of the period. When the interest is compounded quarterly, it means that four times in a year, the amount that is invested and the interest that has already being earned increase in value.

The formula that can be used to determine the quarterly payments is:

Payment = future value / annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

Payment = $96,000 / [{(1.009^72) - 1} / 0.009]  = $953.45

The error in this answer is that : The sum of angle of triangle is 180°

What is Triangle?

A polygon with three edges and three vertices is called a triangle. It is one of the fundamental geometric shapes. Triangle ABC is the designation for a triangle with vertices A, B, and C. In Euclidean geometry, any three points that are not collinear produce a distinct triangle and a distinct plane.

Since, we know that Angle sum property of triangle is

∠A + ∠B + ∠C = 180°

Now, let ∠A = 115, ∠B = 39 and ∠C = m∠1

Substituting the value, we get

115° + 39° + m∠1 = 180°

154° + m∠1 = 180°

m∠1 = 180 - 154

m∠1 = 26°

Thus, m∠1 = 26°

Hence, The error for finding m∠1 is that angle sum of the triangle is equal to 180° and not 360°

The first derivative by implicit differentiation of 2 · x⁶ + 5 · x⁴ · y - 7 · x · y⁶ = 8 is y' = (7 · y⁶ - 20 · x³ · y - 12 · x⁵) / (5 · x⁴ - 42 · x · y⁵).

Implicit differentiation is a differentiation method for implicit functions that combines chain rule and derivative rules. First, define the original function:

2 · x⁶ + 5 · x⁴ · y - 7 · x · y⁶ = 8

Second, use chain rule and derivative rules in the expression of the previous step:

12 · x⁵ + 20 · x³ · y + 5 · x⁴ · y' - 7 · y⁶ - 42 · x · y⁵ · y' = 0

Third, clear y' within the resulting equation:

12 · x⁵ + 20 · x³ · y - 7 · y⁶ + (5 · x⁴ - 42 · x · y⁵) · y' = 0

(5 · x⁴ - 42 · x · y⁵) · y' = 7 · y⁶ - 20 · x³ · y - 12 · x⁵

y' = (7 · y⁶ - 20 · x³ · y - 12 · x⁵) / (5 · x⁴ - 42 · x · y⁵)

The first derivative is y' = (7 · y⁶ - 20 · x³ · y - 12 · x⁵) / (5 · x⁴ - 42 · x · y⁵).

The probability with replacement is = 1/16

The probability without replacement is= 5/16

What do you mean by probability with replacement?

When the results must be put back into the sample space, the probability with replacement is utilized. This means that once an item is selected, it is replaced in the sample space, keeping the sample space's total number of elements constant.

Since cards should be replaced, 5 lions or 5 birds

so, the probability is

= 5/20 ÷ 5/20

=1/16

without replacement,

since cards should not be put back, for the second draw only 19 cards are left

so, the probability is

=5÷20 × 5÷19

=5/16

The correct system of equations is 5x-y=2,x-5y=10

In order to find the system of equations of the graph, we have to check the solution in the graph and then check for the system of equations that gives the same value.

Looking at the graph, the values of x and y at the point of intersection is the solution. Thus:

x =  0 and y = -2

Let's check the equations now:

5x+3y=-6, 3x+5y=-10

Solve for x and y using elimination

3 (5x+3y=-6)

5 (3x+5y=-10)

15x + 9y = -18

15x + 25y = -50

-6y = 32

y = -32/6 = -16/3 (This cannot be the system)

3x-5y=10, x-5y=-10

3x-5y = 10

x-5y = -10

2x = 20

x = 20/2 = 10  (This cannot be the system)

5x-y=2,x-5y=10

1(5x-y=2)

5(x-5y=10)

5x -y =2

5x-25y = 50

24y = -48

y = -48/24 = -2

put y = -2 into 5x -y =2:

5x -(-2) =2

5x + 2 = 2

5x = 0

x = 0

Therefore, 5x-y=2,x-5y=10 is the system of equations. The 3rd option is the answer. Move it to the box
