The points (1,7),(4,2) and (-1,-1) forms a triangle which is.. scalene,equaliteral,or isoceles

Answer»

Answer:

LET the VERTICES of the triangle be

A(1,7), B(4,2), C(-1,-1)

So,

AB = √(1-4)²+(7-2)² = √(-3)²+(5)² = √9+25 = √34

BC = √(4+1)²+(2+1)² = √(5)²+(3)² = √25+9 = √34

CA = √(-1-1)²+(-1-7)² = √(-2)²+(-8)² = √4+64 = √68

Here, AB = BC ≠ CA

⇒ ΔABC is an isosceles Δ.

Is it possible to have a Binomial distribution with mean 5 and standarddeviation 3. Verify your answer mathematically

Answer»

SOLUTION

TO VERIFY

Is it possible to have a Binomial distribution with mean 5 and standard deviation 3

EVALUATION

Let for the given Binomial distribution two parameters are N , p

Then

Mean = np

$\sf{Standard \: Deviation = \sqrt{npq} }$

Now it is given that the Binomial distribution is with mean 5 and standard deviation 3

So by the given CONDITION

$\sf{np = 5 \: \: \: - - - (1)}$

$\sf{ \sqrt{npq} = 3 }$

$\sf{ \implies \: {npq} = 9 }$

$\sf{ \implies \: 5q= 9 }$

$\displaystyle \sf{ \implies \: q= \frac{9}{5} }$

$\displaystyle \sf{ \implies \: 1 - p= \frac{9}{5} }$

$\displaystyle \sf{ \implies \: p= - \frac{4}{5} }$

Which is absurd as probability of an event can not be negative ( 0 ≤ p ≤ 1 )

Hence such Binomial distribution is not possible

12283.

Total distance = 400 mtotal time = 25s.find Average speed.

Answer»

Step-by-step EXPLANATION:

${\red{\underline{\underline{\bold{Given:-}}}}}$

TOTAL distance = 400m

Total TIME = 25 s

${\blue{\underline{\underline{\bold{To\:Find:-}}}}}$

The Average SPEED.

${\green{\underline{\underline{\bold{Solution:-}}}}}$

Formula used :-

$\boxed{Average\: Speed = \frac{Total\: Distance}{Total\:Time}}$

Substituting the values:-

$\bf \: Average \: speed = \frac{400}{25}$

$\bf \: Average \: speed = 8$

$\boxed{Average\: speed = 8m/s}$

Speed in km/hr

To CONVERT speed from m/s to km/h multiply it with 18/5

$\bf \: = 8\times \frac{18}{5}$

$\bf\: = 28.8 km/hr$

If x=-12 then fraction becomes

Step-by-step explanation:

Given that the NUMERATOR of a fraction is 3 less than the denominator. If 4 is added to both the numerator and denominator, the value of fraction INCREASES by 1/8 ,

we have to find the fraction.

Let the denominator of fraction is x

As numerator of a fraction is 3 less than the denominator
