what is euclid's lemma

Answer:

Angle = A

A7 = A4 (Alternate interior angles)

A14 = A11 (Vertically opposite angles)

A11 = A6(Corresponding angles)

A4 = A14 (Given)

From this, we can get A6 = A4

A6 and A4 are alternate angles and are equal. So c and d are parallel.

A7 + A10 = 180 (Linear pair of angles) - ( 1 )

A13 = A10(Alternate interior angles)

Putting A13 in place of A10 in ( 1 ),

A7 + A13 = 180

Hence proved

Answer:

the coordinates of  point M = (2,0)

Step-by-step explanation:

Given;

point S along the segment, = S(4,2)

point Y along the segment, = Y(-4, -6)

ratio of the partition = ¹/₃

total ratio = 1 + 3 =  4

The midpoint of segment SY is calculated as follows;

[tex]mid-point (o) = \frac{x_1 + x_2}{2} ,\ \frac{y_1 + y_2}{2}\\\\ mid-point (o) = \frac{4 + (-4)}{2} , \ \frac{2+ (-6)}{y} \\\\mid-point (o) = \frac{0}{2} , \ \frac{-4}{2} \\\\mid-point (o) = (0, \ -2)[/tex]

The coordinates of point M is calculated as follows;

point M divides the segment into 4 equal parts with point O as the mid-point.

                M

S--------------|-------------------O-------------------|-------------------Y

|SO| = |OY|

[tex]The \ mid-point \ of \ SO = M\\\\Point \ S = (4,2) \\\\Point \ O = (0,-2) \\\\Point \ M = \frac{4 + 0}{2}, \frac{2 - 2}{2} \\\\ Point \ M = 2, 0 \\\\M = (2,0)[/tex]

Therefore, the coordinates of  point M = (2,0)

Step-by-step explanation:

The 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The formula for the confidence interval is:

CI = x ± tα/2 × (s/√n)

where x is the sample mean,

s is the sample standard deviation,

n is the sample size, and

tα/2 is the t-value with (n-1) degrees of freedom and a confidence level of 90%.

From data (x) is 6.25 hours and

s=  4.33 hours.

We also know the sample size (n) is 40.

To find the t-value with (n-1) degrees of freedom and a confidence level of 90%, we can use a t-table.

For 39 degrees of freedom and a confidence level of 90%

Let us find that the t-value is 1.684.

Substituting the values we have into the formula, we get:

CI = 6.25 ± 1.684 × (4.33/√40)

CI = (5.097, 7.404)

Therefore, the 90% confidence interval for the true mean amount of time teenagers from this town watch sports is (5.097, 7.404).

Answer:

Step-by-step explanation:

First do 4 -2 to get 2. Then do 30-15 to get 15. It’s 2:15.

You can also do this on a calculator by doing 4.15-2.30. You get 1.85

Remember that time is only up to 60 So you have to subtract 15 from 85 to get 60. So it’s 2 hours and 15 minutes. Hope this helps!

Answer:

Step-by-step explanation:

Ice forms when the temperature of water reaches 32 degrees Fahrenheit (0 degrees Celsius). When you add salt, that temperature drops: A 10-percent salt solution freezes at 20 °F (-6 °C), and a 20-percent solution freezes at 2 °F (-16 °C). On a roadway, this means that if you sprinkle salt on the ice, you can melt it.

Answer:

19.72 cm²

Step-by-step explanation:

A solid circular cylinder has a base radius 5 cm and a height 12.5 cm.

The volume of cylinder is given by :

[tex]V=\pi r^2 h\\\\=3.14\times (5)^2\times 12.5\\\\=981.25\ cm^2[/tex]

When r = 5.05, new volum becomes,

[tex]V=\pi r^2 h\\\\=3.14\times (5.05)^2\times 12.5\\\\=1000.97\ cm^2[/tex]

Increase in area = 1000.97 - 981.25 = 19.72 cm²

So, the increase in surface area of the cylinder is equal to 19.72 cm².

Explanation:

a) sorry, i can't specifically help with this one unless you attach a picture of the venn diagram. but the way venn diagrams work is that you draw several circles, each representing a trait (i.e. plays rugby). circles will overlap if someone has more than one trait (i.e. plays both sports).

b) the probability is 10 ÷ 25 × 100% = 40%.

Answer:SQ=20

Step-by-step explanation:

NS=20

NS=SQ

SQ=20

The value of SQ is 20

The Greek word "parallelogram on," which means "bounded by parallel lines," is where the term "parallelogram" comes from. As a result, a parallelogram is a quadrilateral with parallel lines defining its boundaries. The opposite sides are parallel and equal in this shape. There are three main classes of parallelograms: square, rectangle, and rhombus each have their own distinct characteristics.

Given a parallelogram NPQR

and NS = 20 to find the value of SQ

since S is the intersecting point of diagonals of parallelogram,

so NS = SQ

The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal. The sum of the squares of a parallelogram's diagonals and all of its sides is the same.

SQ = 20

Hence for parallelogram SQ = 20.
