Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

Since she will use 4 groups or class intervals, the the class width would be 20/4 = 5 hours

The class groups would be

1 to 5

5 to 10

10 to 15

15 to 20

The class mark for each class is the average of the minimum and maximum value of each class. Therefore, the class marks are

(1 + 5)/2 = 3

(5 + 10)/2 = 7.5

(10 + 15)/2 = 12.5

(15 + 20)/2 = 17.5

The frequency table would be

Class group Frequency

1 - 5 4

5 - 10 8

10 - 15 6

15 - 20 2

The total frequency is 4 + 8 + 6 + 2 = 20

Answer:

a = 10 1/4

Step-by-step explanation:

So with the following equation,

4/5a - 8 = 1/5,

we need to use the commutative property.

Which is the moving of whole numbers or variables.

So we add 8 to both sides.

4/5a = 41/5

Divide 4/5 by both sides

a = 10 1/4

So on of the equations could look like a = 10 1/4

Thus,

a = 10 1/4 could be one of the equations given which are equal to 4/5a - 8 = 1/5.

Hope this helps :)

Answer:

Answer

A view which Felix can use to construct the same figure include the following: A. a bottom row of 6 cubes, second row of 3 cubes, and top row of 1 cube.

In Mathematics and Geometry, an isometric sketch is sometimes referred to as an isometric drawing and it can be defined as a graphical (pictorial) representation of a physical object or geometric shape in technical and engineering drawings, especially by drawing all its three dimensions (3D) at full scale;

In this context, we can reasonably infer and logically deduce that the front view is a view which Felix can use to construct the same three-dimensional figure because its orientation influences the other views.

Answer:

Equation is Y=mx+c (that's how I know it, it may differ)

Step-by-step explanation:

First get the slope which is M and you just gotta do the second y - the first y from the brackets and divide them by the second x - the first x

6-1 /-2-3 = 5/-5

= -1

So now u gotta find c, C= Y-mx

And u have got two brackets, which have an x and y, and u now have m.

Pick one of the brackets like (-2,6) and put them in the equation so it will be : C =6+1*-2

So C =4

The equation now is : Y = - 1x + 4

Answer:

The answer is 82 square feet

Step-by-step explanation:

An easy way to do this is to split it into two rectanlges. You can do 10*5 and 8*4 as the dimensions to the two rectangles or you can do 2*4 and 9*8.

I am going to do the first option.

The area of a rectangle is length times width.

Rectangle one can be the one with the dimensions 10 and 5 and the length and width.

Rectangle two can be the one with the dimensions 8 and 4 and the length and width.

Area of rectangle one = 50 feet^2

Area of rectangle two = 32 feet^2

Since we split a large irregular shape into two bits, we must add them together, which results in 82 feet^2.

Answer:

\(k=35\)°

Step-by-step explanation:

The degree measure of a straight line is (180) degrees. Therefore, when a line intersects another line, the sum of angle measures on any one side of the line is (180). One can apply this here to find the supplement (the angle on the same side of the line) of the angle with a measure of (130) degrees, and (85) degrees.

\(130 + (unknown_1)=180\\unknown_1=50\\\\85+(unknown_2)=180\\unknown_2=95\)

The sum of angle measures in a triangle is (180) degrees, one can apply this here by stating the following;

\((unknown_1)+(unknown_2)+(k)=180\)

Substitute,

\(50+95+k=180\)

Simplify,

\(50+95+k=180\\\\145+k=180\\\\k=35\)

\(\sf \bf {\boxed {\mathbb {TO\:FIND :}}}\)

The measure of angle \(k\).

\(\sf \bf {\boxed {\mathbb {SOLUTION:}}}\)

\(\implies {\blue {\boxed {\boxed {\purple {\sf {k\:=\:35°}}}}}}\)

\(\sf \bf {\boxed {\mathbb {STEP-BY-STEP\:\:EXPLANATION:}}}\)

We know that,

\(\sf\pink{Sum\:of\:angles\:on\:a\:straight\:line\:=\:180°}\)

➪ \(x\) + 85° = 180°

➪ \(x\) = 180° - 85°

➪ \(x\) = 95°

Also,

Exterior angle of a triangle is equal to sum of two opposite interior angles.

And so we have,

➪ 130° = \(k\) + \(x\)

➪ \(k\) + 95° = 130°

➪ \(k\) = 130°- 95°

➪ \(k\) = 35°

Therefore, the value of \(k\) is 35°.

\(\sf \bf {\boxed {\mathbb {TO\:VERIFY :}}}\)

\(\sf\blue{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}\)

➪ 50° + 35° + 95° = 180°

( where 50° = 180° - 130°)

➪ 180° = 180°

➪ L. H. S. = R. H. S.

Hence verified.

Answer:

Step-by-step explanation:

Given information: $\sf\:\csc(x) = 8$, $90° < x < 180° \\$

To find $\sf\:\sin(\frac{x}{2}) \\$, $\sf\:\cos(\frac{x}{2}) \\$, and $\sf\:\tan(\frac{x}{2}) \\$:

Step 1: Rewrite the given information:

$\sf\:\csc(x) = \frac{1}{\sin(x)} = 8 \\$

Step 2: Solve for $\sf\:\sin(x) \\$:

$\sf\:\sin(x) = \frac{1}{8} \\$

Step 3: Use the half-angle identity for $\sf\:\sin(\frac{x}{2}) \\$:

$\sf\:\sin(\frac{x}{2}) = \pm \sqrt{\frac{1 - \cos(x)}{2}} \\$

Since $\sf\:90° < x < 180°$, $\sf\:\cos(x)$ will be negative, so we take the positive square root:

$\sf\:\sin(\frac{x}{2}) = \sqrt{\frac{1 - \cos(x)}{2}} \\$

Step 4: Find $\sf\:\cos(x)$ using the Pythagorean identity:

$\sf\:\sin^2(x) + \cos^2(x) = 1 \\$

Substituting $\sf\:\sin(x) = \frac{1}{8} \\$:

$\sf\:(\frac{1}{8})^2 + \cos^2(x) = 1 \\$

$\sf\:\frac{1}{64} + \cos^2(x) = 1 \\$

$\sf\:\cos^2(x) = 1 - \frac{1}{64} \\$

$\sf\:\cos^2(x) = \frac{63}{64} \\$

Taking the square root of both sides:

$\sf\:\cos(x) = \pm \sqrt{\frac{63}{64}} \\$

Since $\sf\:90° < x < 180°$, $\sf\:\cos(x)$ will be negative, so we take the negative square root:

$\sf\:\cos(x) = -\sqrt{\frac{63}{64}} \\$

Step 5: Use the half-angle identity for $\sf\:\cos(\frac{x}{2})$:

$\sf\:\cos(\frac{x}{2}) = \pm \sqrt{\frac{1 + \cos(x)}{2}} \\$

Since $\sf\:90° < x < 180°$, $\sf\:\cos(x)$ will be negative, so we take the negative square root:

$\sf\:\cos(\frac{x}{2}) = -\sqrt{\frac{1 + \cos(x)}{2}} \\$

Step 6: Find $\sf\:\tan(\frac{x}{2}) \\$ using the identity $\sf\:\tan(\frac{x}{2}) = \frac{\sin(\frac{x}{2})}{\cos(\frac{x}{2})} \\$:

$\sf\:\tan(\frac{x}{2}) = \frac{\sqrt{\frac{1 - \cos(x)}{2}}}{-\sqrt{\frac{1 + \cos(x)}{2}}} \\$

Simplifying:

$\sf\:\tan(\frac{x}{2}) = -\sqrt{\frac{1 - \cos(x)}{1 + \cos(x)}} \\$

Therefore, the values are:

$\sf\:\sin(\frac{x}{2}) = \sqrt{\frac{1 - \cos(x)}{2}} \\$

$\sf\:\cos(\frac{x}{2}) = -\sqrt{\frac{1 + \cos(x)}{2}} \\$

$\sf\:\tan(\frac{x}{2}) = -\sqrt{\frac{1 - \cos(x)}{1 + \cos(x)}} \\$

Please note that the sign of the values may change depending on the actual value of $\sf\:\cos(x)$, which is negative in this case.
