The value of x, considering the consecutive interior angles in this problem, is given as follows:

x = 30.

We have two parallel lines that are cut by a transversal, and the two angles are between the parallel lines and on the same side of the transversal, meaning that they are consecutive interior angles.

Consecutive interior angles are supplementary, meaning that the sum of their measures is of 180º, hence the value of x can be found as follows:

3x - 8 + 4x - 22 = 180

7x - 30 = 180

7x = 210

x = 210/7

x = 30.

The smaller the sample size, the greater the uncertainty in our estimate.

From the options, 37.5% is obtained from the smallest sample size (8) and thus the percent is expected to be furthest away from this value.

Answer: 37.5%.

The exact value of sin(5π/12) is (√6 + √2)/4

From the question, we have the following parameters that can be used in our computation:

sin 5pi/12

Express properly

So, we have

sin(5π/12)

Convert the angle to degrees

This gives

sin(5π/12) = sin(5/12 * 180)

Evaluate

sin(5π/12) = sin(75)

The actual value of sin(75) is (√6 + √2)/4

This means that

sin(5π/12) = (√6 + √2)/4

Hence, the exact value of sin(5π/12) is (√6 + √2)/4

The exact value of sin 5π/12 is (√6 + √2)/4

The trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths.

Angle in trigonometry can be measured in either degree or radian.

π is a measurement in radian which is equivalent to 180° in degrees.

Therefore:

5π/12 = 5 × 180/12

= 75°

Therefore sin5π/12 = sin75°

sin75 = sin( 45+30) = sin45cos30+ cos 45sin30

= 1/√2 × √3/2 + 1/√2 × 1/2

= √3/2√2 + 1/2√2

= (√3+1)/2√2

rationalizing;

(2√6 + 2√2)/8

dividing through by 2

=(√6 + √2)/4

therefore tan75 =(√6 + √2)/4

Answer:

-20+5x=2.

Step-by-step explanation:

..............

Answer:

FH = 35.64

Step-by-step explanation:

(∠A = 360 so the other angle is 40)

By law of cosines,

FH² = AH² + FA² - 2(AH)(FA) * cos(A)

= 30² + 25² - 2(30)(25) * cos(80)

= 900 + 625 - 1500 * 0.17

= 1525 - 255

FH²  = 1270

FH = √1270

FH = 35.64

The angle of the T in the ΔRST is 100° and the value of p is 11.

Define Triangle.

A triangle is a polygon that consists of three sides and three vertices. The fact that the interior angles of a triangle add up to 180 degrees is the most crucial aspect of triangles. This characteristic is known as the angle sum property of a triangle.

i.e., In a give ΔABC, ∠A + ∠B + ∠C = 180°.

Given:

∠R = 37°; ∠S = 43°; ∠T = 10p-10°

Let's take ∠T = x

In ΔRST,

∠R + ∠S + ∠T = 180°

37 + 43 + x =  180°

x = 180 - 80 ⇒ 100

∴ ∠T = 100°

To find the value of p,

 ∠T = 100

10p - 10 = 100

10p = 110 ⇒ 11

∴ p = 11

Answer:

First step: Combine like terms, Answer: \(x=15\)

Step-by-step explanation:

First, we need the variable on the left side and constants on the right.

So, we combine like terms to get \(3x=36+9=45\).

Then, we can divide both sides by \(3\) to isolate the variable and get \(\boxed{x=15}\).

Answer : The different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.

Step-by-step explanation :

As see that, AB is a line segment in which point C is represented in between the line.

As we are given that:

AC = 3

CB = 7

So,

AC + CB = 3 + 7 = 10

Similarly,

CA + BC = 3 + 7 = 10

Similarly,

AB = AC + CB = 3 + 7 = 10

But,

BC - AC = 7 - 3 = 4

From this we conclude that, find AC + CB, find AB and find CA + BC are same things while find BC - AC is a different thing.

Hence, the different is, find BC - AC and find AC + CB, find AB and find CA + BC are same.

The correct value of 2f(a-1) is 2a^2 - 12a + 10.

To find the value of 2f(a-1), we need to substitute (a-1) into the function f(x) and then multiply the result by 2.

Given: f(x) = x^2 - 4x

Substituting (a-1) into the function:

f(a-1) = (a-1)^2 - 4(a-1)

Expanding and simplifying:

f(a-1) = (a^2 - 2a + 1) - (4a - 4)

f(a-1) = a^2 - 2a + 1 - 4a + 4

f(a-1) = a^2 - 6a + 5

Now, we multiply the result by 2:

2f(a-1) = 2(a^2 - 6a + 5)

Expanding:

2f(a-1) = 2a^2 - 12a + 10

Therefore, the value of 2f(a-1) is 2a^2 - 12a + 10.

CI = (51.32, 58.68)

2)(a) The value of the population proportion is; 0.625

b) The standard error of the proportion is; 0.0624

c) A 99% CI for the population proportion is; CI = (0.5626, 0.6874)

d) The interpretation is that the proportion of those who watched the new show and suggested it replace the crime investigation show is between 0.5626 and 0.6874

1) We are given;

Sample size; n = 49

Sample Mean; x' = 55

Standard deviation; s = 10

Confidence level = 99%

Formula for confidence level is;

CI = x' ± z(s/√n)

z at 99% is; 2.576

Thus;

CI = 55 ± 2.576(10/√49)

CI = (51.32, 58.68)

2) The formula for confidence interval for proportion is;

CI = p ± z√(p(1 - p)/n)

We are given;

Sample size; n = 400

X = 250

a) Thus, population proportion = 250/400 = 0.625

b) Standard error is given by the formula;

SE = z√(p(1 - p)/n)

SE = 2.576√(0.625(1 - 0.625)/400)

SE = 0.0624

c) The  99% CI for the population proportion is;

CI = 0.625 ± 0.0624

CI = (0.5626, 0.6874)

The expression will be; part (a) (f o g)(-2) = 2 and part (b) (g o f)(-2) = -95

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given the functions as;

f(x)=4x-2

g(x)=5-x^2

We need to find (f o g)(-2)

So, first, we will find the function (f o g)(x) as follows:

\(\begin{gathered} \mleft(f\circ g\mright)(x)=f\lbrack g(x)\rbrack=4(5-x^2)-2 \\ (f\circ g)(x)=20-4x^2-2 \\ (f\circ g)(x)=18-4x^2 \end{gathered}\)

Now, substitute with x = -2 then we get;

\((f\circ g)(-2)=18-4\cdot(-2)^2=18-4\cdot4=18-16=2\)

Thus, the answer to the part is (a) (f o g)(-2) = 2

b) (g o f)(-2)

We need to find (g o f)(x) as follows:

\((g\circ f)(x)=g\lbrack f(x)\rbrack=5-(4x-2)^2\)

Now Substitute with x = -2, then we get;

\(\begin{gathered} (g\circ f)(-2)=5-(4\cdot-2-2)^2 \\ =5-(-8-2)^2 \\ =5-(-10)^2 \\ =5-100 \\ =-95 \end{gathered}\)

Thus, the answer to the part (b) is (g o f)(-2) = -95

The antiderivative of the function is t³/3 i + ln |cos(t)| j.

option C.

The antiderivative of the function is calculated as follows;

r = t²i + tan(t)j

tan(t) = sin(t)/cos(t)

Substituting sin(t)/cos(t) for tan(t) in the given function;

r = t²i + (sin(t)/cos(t))j

The antiderivative of sin(t)/cos(t) with respect to t is calculated as;

u = cos(t)

du = -sin(t)dt

∫ (sin(t)/cos(t)) dt = -∫ du/u

= -ln |u| + C

= -ln |cos(t)| + C

The antiderivative of t² is calculated as;

∫ t² dt = t³/3 + C
