The linear equation represented in the table is:

y = -3x + 20

A general linear equation of the form is:

y = a*x + b

We know that if a line passes through two points (x₁, y₁) and (x₂, y₂) then the slope is:

slope = (y₂ - y₁)/(x₂ - x₁)

Here we can use the last two points on the table:

(-2, 26) and (-4, 32)

Then the slope is:

slope = (26 - 32)/(-2 + 4) = -6/2 = -3

So this is like:

y = -3*x + b

To find the value of b we can use one of the points, i will use (-2, 26), then:

26 = -3*-2 + b

26 = 6 + b

26 - 6 = b = 20

The linear equation is y = -3x + 20

The solution of the system of equation is as follows:

The system of equation can be solved algebraically using substitution method.

The system of equation can be solved when we find the value of x and y as follows:

y = 4x + 1

6x - 2y = 3

Let's substitute the equation(i) in equation(ii)

6x + 2(4x + 1) = 3

6x + 8x + 2 = 3

14x + 2 = 3

14x = 3 - 2

14x = 1

x = 1 / 14

let's find y as follows:

If Justin bought a calculator and a binder that were both 15% off the original price. The original price of the binder was $6.20. Justin spent a total of $107.27. Then $120 the original price of the calculator

A percentage is a number or ratio expressed as a fraction of 100.

Let,

x be the original price of the calculator

y be the original price of the binder

we know that

15%=15/100=0.15

(x+y)(1-0.15)=$107.27

(x+y)(0.85)=$107.27....(1)

y=6.20....(2)

substitute the value of y in the equation A and solve for x

(x+6.20)(0.85)=107.27

(x+6.20)=107.27/0.85

x=107.27/0.85-6.20

x=126.20-6.20

x=120

Hence the original price of calculator is $120.

The number of the students should be sampled to be within 0.25  alcoholic drinks of population mean with 95% probability is 62.

α is the result of subtracting one from confidence interval as well as dividing by two.

α =  (1 - 0.95) ÷ 2 = 0.25

Find z in the Z-table because z does have a p-value of 1 - α.

As a result, the p-value of z is  (1 - 0.025) = 0.975.

Thus, z  = 1.96

Now find M as;

M = z × (σ ÷ √n)

In which,

When M = 1,

The standard deviation, in accordance with the question, is approximately 1.

σ = 1

M = z × (σ ÷ √n)

0. 25 = 1.96 × (1 ÷ √n)

√n = 1.96 × (1 ÷ √n)

Squaring both sides,

(√n)² = ((1.96 × 1) ÷ 0.25)²

n = (7.84)²

n = 61.4656

n ≈ 62

Thus, the number of the students should be sampled to be within 0. 25 alcoholic drink of population mean with 95% probability is 62.

The trigonometric functions for the angle of 195º are given as follows:

1. cos(195º) = -0.9659.

2. sin(195º) = -0.2589.

3. tan(195º) = 0.2680

The identity is verified at the end of the answer.

One of the functions have to be given/found using a calculator, hence:

cos(195º) = -0.9659.

The sine and the cosine of the same angle are related according to the following identity:

sin²(x) + cos²(x) = 1.

Hence:

sin²(195º) + cos²(195º) = 1

sin²(195º) + (-0.9659)² = 1

sin²(195º) + 0.93296281 = 1

sin²(195º) = 1 - 0.93296281.

sin(195º) = ±sqrt(1 - 0.93296281)

sin(195º) = -0.2589. (the angle of 195º is on the third quadrant, where both the sine and the cosine are negative).

The tangent of an angle is given by the sine of the angle divided by the cosine of the angle, hence:

tan(195º) = sin(195º)/cos(195º) = -0.2589/(-0.9659) = 0.2680. (negative divided by negative is positive)

The identities for the sine of the sum and of the subtraction are given as follows:

Hence the subtraction is:

sin(x + y) - sin(x - y) = (sin(x)cos(y) + cos(x)sin(y)) - (sin(x)cos(y) - cos(x)sin(y))

sin(x + y) - sin(x - y) = sin(x)cos(y) + cos(x)sin(y) - sin(x)cos(y) + cos(x)sin(y)

sin(x + y) - sin(x - y) = 2cos(x)sin(y).

The percent error of the actual measurement of 10 fluid ounces is 25%.

Percent error:

Percent error means the difference between the exact or known value of something and its approximate or actual value, in percentage form.

The formula to calculate the percent id defined as

δ = |(A - E)/E| x 100%

Where

δ  = percent error

A  = actual value observed

E  = expected value

Given,

Derek filled the pitcher with 8 fluid ounces of lemonade.

Here we need to find the percent error if the actual measurement was 10 fluid ounces.

According to the percent error formula, the actual value in the given question is 10 and the expected value is 8.

Then we have to apply the value on the formula, then we get,

Percent error = [(10 - 8)/8] x 100%

Percent error = [2/8] x 100%

Percent error = 0.25 x 100%
