The value of DC is of 80, hence the statement is false.

Similar triangles share these two features listed as follows:

The similar triangles for this problem are given as follows:

AOB and COD.

Hence the proportional relationship established between the side lengths is given as follows:

OA/OC = OB/OD = 1/4 = AB/DC.

Taking the last two terms, considering that AB = 20 cm, the length of DC is given as follows:

DC = 4 x AB

DC = 4 x 20 cm

DC = 80 cm.

Hence the statement is false, as the length is of 80 cm and not of 120 cm.

Answer:

1. consistent independent
2. consistent dependent
3. inconsistent

Step-by-step explanation:

1. when we take the ratios of the two equations,
[tex]a_{1} : a_{2} \neq b_{1} :b_{2}[/tex]

2. when we take the ratios of the two equations,
[tex]a_{1} : a_{2} = b_{1} :b_{2} = c_{1} : c_{2}[/tex]

1. when we take the ratios of the two equations,
[tex]a_{1} : a_{2} = b_{1} :b_{2} \neq c{1} : c_{2}[/tex]

Step-by-step explanation:

4x + y = 8

x + 3y = 8

consistent independent

both equations are lines with different slope.

so, they intersect at one point.

that is the solution.

-4x + 6y = -2

2x - 3y = 1

consistent dependent

both equations are actually identical lines.

multiply the second equation by -2.

and you see the equality.

that means every point is a solution.

there are infinitely many solutions.

5x - 2y = 4

5x - 2y = 6

inconsistent

both equations are lines with identical slopes.

but with different y-intercepts.

they are parallel and never intersect.

there is no solution.

there is no (x, y) that their sum has 2

different results.

The length of DE is  25. So correct option is (4).

In geometry, the term "parallel" refers to two lines that are equidistant from each other over their entire length and will never intersect, no matter how far they are extended. In other words, two parallel lines are parallel if they lie in the same plane and maintain the same distance between them at all times.

Since AB is parallel to DE and BD is perpendicular to both AB and DE, by alternate interior angles, we have:

angle BDA = angle DEC

Since BD is 7 and BC is 15, we have:

triangle BCD is a 7-15-17 right triangle (the Pythagorean theorem)

So, angle BDA = angle DEC = 90 - arctan(7/15) = arctan(15/7).

Also, since AB is parallel to DE, and BD is perpendicular to both AB and DE, we have:

angle ABD = angle CDE

So, by the vertical angles theorem, we have:

angle ABD = angle CDE = 90 degrees - arctan(15/7) = arctan(7/15)

Then, by the Pythagorean theorem, the length of DE can be found as:

[tex](DE)^{2}[/tex] = [tex](AB)^{2}[/tex] + [tex](BD)^{2}[/tex] = [tex]21^{2}[/tex] + [tex]7^{2}[/tex] = 441 + 49 = 490

So, DE = [tex]\sqrt{490}[/tex] = 2[tex]\sqrt{122}[/tex] = 2 * 11 = 22

Therefore, the length of DE is (4) 25.

To put the streamer on the whole wall we need at least 32 Square feet of the streamer.

The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.

Given,  to put streamers from concern to corner in both directions and the wall is 4 ft wide and 8ft high.

Since the area of a rectangle:

Area  = Length * width

Thus,

The area of the wall  = 4 * 8

The area of the wall  = 32

a) The probability that the player makes exactly 3 of the 5 shots = 0.3087

b) The probability that the player makes exactly 4 of the 5 shots = 0.36015

c) The probability that the player makes all 5 shots = 0.16807

d) The probability that the player makes 3 or 4 of the shots = 0.66885

The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.

The formula for Binomial Distribution is given by

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

where

n = number of trials

x = number of successes

p = probability of getting a success in one trial

q = probability of getting a failure in one trial

q = 1 - p

Given data ,

Let the probability be represented as P

The total number of trials n = 5

The probability of getting a success p = 0.70

The probability of getting a failure q = 0.30

Now , the equation will be

a)

The probability that the player makes exactly 3 of the 5 shots = A

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

n = 5

x = 3

Substituting the values in the equation , we get

A = ⁵C₃ ( 0.70 )³ ( 0.30 )²

A = 10 ( 0.343 ) ( 0.09 )

A = 0.3087

So , probability that the player makes exactly 3 of the 5 shots is 0.3087

b)

The probability that the player makes exactly 4 of the 5 shots = B

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

n = 5

x = 4

Substituting the values in the equation , we get

B = ⁵C₄ ( 0.70 )⁴ ( 0.30 )¹

B = 5 ( 0.2401 ) ( 0.3 )

B = 0.36015

So , probability that the player makes exactly 4 of the 5 shots is 0.36015

c)

The probability that the player makes all 5 shots = C

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

n = 5

x = 5

Substituting the values in the equation , we get

C = ⁵C₅ ( 0.70 )⁵ ( 0.30 )⁰

C = 0.16807

So , probability that the player makes all 5 shots is 0.16807

d)

The probability that the player makes 3 or 4 of the shots = D

D = A + B

D = 0.3087 + 0.36015

D = 0.66885

Hence , the probability is solved

Step-by-step explanation:

To solve this problem, we'll use the exponential growth formula:

P(t) = P0 * e^(rt)

Where P(t) is the population after t years, P0 is the initial population (1543), r is the growth rate (0.038), and t is the number of years (5.2).

P(5.2) = 1543 * e^(0.038 * 5.2)

Using a calculator or natural logarithm rules:

P(5.2) = 1543 * e^0.199

P(5.2) = 1543 * 1.22

P(5.2) = 1887.46

So the population will be approximately 1887.46 after 5.2 years.

The value of function f ' (2) is, 7/4.

To find the value of any one of the variables from one equation in terms of the other variable is called the substitution method.

We have to given that;

The function is,

⇒ f (x) = 7/x

Now, We an solve as;

⇒ f ' (2) = lim h → 0 ( f (2 + h) -  f (2) / h )

⇒ f ' (2) = lim h → 0 ( 7 / (2 + h) - 7/2 / h )

⇒ f ' (2) = lim h → 0 ( 7/h (2 - 2 - h) / (2 + h)×2)

⇒ f ' (2) = lim h → 0 ( 7/h ( - h ) / 2 (2 + h) )

⇒ f ' (2) = lim h → 0 ( - 7 / 2 (2+ h))

⇒ f ' (2) = - 7/4

the profit is 20

Step-by-step explanation:

Answer:

Rs 20

Step-by-step explanation:

S.P. (Selling Price) is the price at which a product is sold. C.P. (Cost Price) is the price at which a product is purchased. When S.P. is greater than C.P., it results in a profit. To calculate profit, the formula is simple:

Profit = S.P. - C.P.

In this case, S.P. is Rs. 210 and C.P. is Rs. 190. So, the profit would be calculated as:

Profit = Rs. 210 - Rs. 190 = Rs. 20.
