Answer:

20

Step-by-step explanation:

To Find the Median do the following below;

16, 16, 16, 19, 20, 22, 23, 24, 24

16, 16, 16, 19, 20, 22, 23, 24, 24

16, 16, 16, 19, 20, 22, 23, 24, 24

16, 16, 16, 19, 20, 22, 23, 24, 24

Thus, Median is 20.

Answer:

cos F is 15/28

Step-by-step explanation:

Use SOH CAH TOA

CAH is for cosine and it's Adjacent over Hypotenuse

the adjacent side of F is 15 and the hypotenuse is 28

So 15/28 which does not simplify

Answer:

I think it will be the first one because as we can see the points are going up which tells us the line would be positive.

if the -8-13 are both in the denominator

-24/(-8-13)

-24/-21

divide both sides by -3

[-24/-3] / [-21/-3]

8 / 7

if the -13 comes after the division

(-24/-8) -13

3 - 13

Answer:

Geometry has influenced how civilizations have constructed buildings and stadiums. In Ancient Greece, the “golden rectangle” was used to build aesthetically pleasing buildings that look to be in perfect proportion. It helps in the accurate calculation of the physical distances. It is employed in the field of astronomy to map the distances between stars & planets and between different planets. It also aids in the determination of a relationship between the movements of different bodies in the celestial environment.

The percentage of runners having times less than 14.4 sec is 0.15%. Then the correct option is A.

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The times of all 15-year-olds who run a certain race are approximately normally distributed with a given mean (μ) = 18 sec and standard deviation (σ) = 1.2 sec.

The runners have times less than 14.4 sec.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

[tex]\rm z-score = \dfrac{X - \mu}{\sigma }\\\\z-score = \dfrac{14.4- 18}{1.2}\\\\z-score = -3[/tex]

Then the Percentage will be

[tex]\rm P(X < 14.4) = P(z < -3) = 0.0013499 = 0.13499\ \% \approx 0.15\ \%[/tex]

Answer:

-11w^2+13

Step-by-step explanation:

(-13w^2+13)-(-2w^2)

Distribute the minus sign

-13w^2+13+2w^2

Combine like terms

-13w^2+2w^2+13

-11w^2+13

Step-by-step explanation:

geometric sequence means that every term is created by multiplying the previous term by a constant factor.

we can see the constant factor directly, I am sure, but let's do it formally correct :

-1/8 × f = -1/4

f = -1/4 / -1/8 = -1/4 × -8/1 = -8/-4 = 2

so, yes, every new term of the sequence is created by multiplying the previous term by 2.

a0 = -1/8

a1 = a0 × 2 = -1/8 × 2 = -2/8 = -1/4

a2 = a1 × 2 = a0 × 2×2 = -1/8 × 2×2 = -1/8 × 4 = -4/8 = -1/2

...

an = a0 × 2^n = -1/8 × 2^n

a6 = -1/8 × 2⁶ = -1/8 × 64 = -8

so, the only questing is, where does your teacher start the count for such a geometric sequence ?

do you call the first term a0 or a1 ?

my solution above starts with a0.

but if it should start with a1, then we need to reduce the exponents of 2 by 1 :

an = -1/8 × 2^(n-1)

and a6 would be

a6 = -1/8 × 2⁵ = -1/8 × 32 = -4

Answer:

60=3x+27(The corresponding elements of the angular triangles are similar.)

60-27=3x

33=3x

33/3=3x/3

11=x

x=11

Answer:

The area of a triangle can be determined with the two side lengths, the length and breadth/width multiplied.

x = unknown value of breadth/width

23 = length

506 = the area of the two lengths multiplied

23(x) = 506

/23        /23

x = 22, 22 metres is it's breadth.

Answer:

22m is the breadth of the rectangle.

Step-by-step explanation:

Given:

To Find:

[tex] \: [/tex]

Solution:

As, we know,

[tex]{ \boxed{ \pink{Area _{(rectangle)} \: = length \times breadth}}}[/tex]

➝ 506m² = l × b

➝ 506m² = 23 × b

➝ b = 506/23 = 22

Hence, Breadth of the Rectangle is 22m.

[tex] \: [/tex]

Area = length × breadth

➝ 23 × 22

➝ 506m²

[tex]{ \sf{Additional \: Information}}[/tex]

[tex]\boxed{\begin {array}{cc}\\ \dag\quad \Large\underline{\bf{ \green{ Formulas\:of\:Areas:-}}}\\ \\ \star\sf Square=(side)^2\\ \\ \star\sf Rectangle=Length\times Breadth \\\\ \star\sf Triangle=\dfrac{1}{2}\times Base\times Height \\\\ \star \sf Scalene\triangle=\sqrt {s (s-a)(s-b)(s-c)}\\ \\ \star \sf Rhombus =\dfrac {1}{2}\times d_1\times d_2 \\\\ \star\sf Rhombus =\:\dfrac {1}{2}d\sqrt {4a^2-d^2}\\ \\ \star\sf Parallelogram =Base\times Height\\\\ \star\sf Trapezium =\dfrac {1}{2}(a+b)\times Height \\ \\ \star\sf Equilateral\:Triangle=\dfrac {\sqrt{3}}{4}(side)^2\end {array}}[/tex]

Assuming that this is a parallelogram, that means the angle opposite each other like Angle L to Angle J and Angle K to Angle M are equal in angle measure.

Thus Angle L is 98 degrees like Angle J
