Answer:

Choices B, C, and D are correct.

Step-by-step explanation:

Euclid's Five postulates are as follows:

<em>1. A straight line segment may be drawn from any given point to any other.</em>

<em>2. A straight line may be extended to any finite length.</em>

<em />

<em>3. A circle can be drawn with any center and radius.</em>

<em />

<em>4. All right angles are congruent/equal to each other.</em>

<em />

<em>5. Through a point not on a given line, there is exactly one line parallel to the given line.</em>

Now looking at these postulates and the choices we are given we see that only choice B, C, and D match with above.

Learning Task 1: Illustrate the following fractions on your notebook.
Marizza181 [45]

Answer:

The illustration is found in the attachment below.

<em>Note: The correct order of the question is found below:</em>

<em>Learning Task 1: Illustrate the following fractions on your notebook.</em>

<em>a.)2/3 b.)7/9 c.)10/12 d.)8/12 e.)4/5 f.) 8/6 g.)9/4 h.) 28/10</em>

Step-by-step explanation:

a) Draw a rectangle of sides 3 cm by 1 cm. Divide the rectangle into three equal parts. Shade two out of the three parts to give the fraction 2/3

b)  Draw a rectangle of sides 9 cm by 1 cm. Divide the rectangle into nine equal parts. Shade seven out of the nine parts to give the fraction 7/9

c)  Draw a rectangle of sides 12 cm by 1 cm. Divide the rectangle into twelve equal parts. Shade ten out of the twelve parts to give the fraction 10/12

d)  Draw a rectangle of sides 12 cm by 1 cm. Divide the rectangle into twelve equal parts. Shade eight out of the twelve parts to give the fraction 8/12

e)  Draw a rectangle of sides 5 cm by 1 cm. Divide the rectangle into five equal parts. Shade four out of the five parts to give the fraction 4/5

f)  Draw two rectangle of sides 6 cm by 1 cm. Divide the rectangles into six equal parts each. Shade all the six parts of the first rectangle completely. Then, shade two out of the six parts of the second rectangle to give the fraction 8/6

g) Draw three rectangles of side 4 cm by 1 cm. Divide each of the three rectangles into four parts each. Shade completely the four parts of the first and second rectangle. Then, shade one part out of the four parts of the third rectangle to give the fraction 9/4

h) Draw three rectangles of side 10 cm by 1 cm. Divide each of the three rectangles into ten parts each. Shade completely the ten parts of the first and second rectangle. Then, shade eight parts out of the ten parts of the third rectangle to give the fraction 28/10

Why math even exist people could just like wing it for everything
s2008m [1.1K]

Answer:

- 7 / 4

Step-by-step explanation:

( x1, y1 ) = ( 1, 10 )

Here,

x1 = 1

y1 = 10

( x2, y2 ) = ( 5, 3 )

Here,

x2 = 5

y2 = 3

Formula : -

Slope = ( y2 - y1 ) / ( x2 - x1 )

Slope = ( 3 - 10 ) / ( 5 - 1 )

Slope = - 7 / 4

Proper fraction = - 7 / 4

For the histogram on the right determine whether the mean is greater​ than, less​ than, or approximately equal to the median. Ju
Vikentia [17]

Answer:

Option D is correct.

x overbar less than Upper M because the histogram is skewed left.

Step-by-step explanation:

Note that x overbar represents the mean and upper M represents the median.

The median is the variable at the middle of the distribution of distribution when all the variables are arranged in ascending or descending order.

The total frequency for this distribution is 3+4+7+10+13+10 = 47

the median will be at the middle of this distribution; that is, at the 24th position.

The 24th position is on the 4th bar (the very end of the 4the bar).

The mean is the average of a distribution. It is the sum of variables in the distribution divided by the number of variables in the distribution.

For an histogram, the number in the middle of each bar is used to calculate the mean.

Let us assume that the width of each bar is 5 and the midpoint of the first bar is x, then the midpoint of the next bar will be x+5, the next bar will be x+10, etc.

Sum of the variables = (x)(3) + (x+5)(4) + (x+10)(7) + (x+15)(10) + (x+20)(13) + (x+25)(10) = 47x + 750

mean = (47x+750)/47

Mean = (x + 15.95)

This value indicates that the mean is on the 4th bar. But like we obtained, the median was at the end of the 4th bar, the mean is closer to the midpoint of the bar. (Recall that the midpoint of the bar is x+15).

This indicates that the mean is less than the median.

When the mean is less than the median, it means that less variables fall below the mean, more variables are found above the mean and it is a skewed left distribution.

Hope this Helps!!!

Anyone know the answer to this?
stira [4]

Answer:

124.80 ft

Step-by-step explanation:

Height of Daniel = 6 ft

The angle of elevation from his eyes to the top of the statue is = 68°

Daniel is 48 ft away from the base of the statue

To find the height of the statue apply the tangent of an angle formula then add height of Daniel as;

Tan 68° = h/48

h= {48 tan 68°} + 6 ft

h= 124.804168964

h= 124.80 ft
