Answer:

10,15,20

Step-by-step explanation:

Pythagorean triple is when three number satisfies a^{2} +b^{2} =c^{2}.

For  3,4,5

if a=3, b=4 and c=5

then

(3)^{2} +(4)^{2} =(5)^{2}

9 +16 =25

25 =25

The left hand and right hand side are satiesfied.

So, the numbers 3,4,5 are Pythagorean triple.

For  10,15,20

if a=10, b=15 and c=20

then

(10)^{2} +(15)^{2} =(20)^{2}

100 +225 =400

325\neq400

The left hand and right hand side are not satiesfied.

So, the numbers 10,15,20 are not Pythagorean triple.

Hence, we get the set of numbers which are not Pythagorean triple that is <u>10,15,20.</u>

mr Goodwill [35]

So the formula for a circle is Pie * r^2

If you divide 300 by pie and then Square root it you would get your radius

And once you have the radius you would use the equation of 2pie * r to find the circumfrence.

Answer is 61.38

Hope this helps!

In a certain game of chance, your chances of winning are 0.3. Assume outcomes are independent and that you will play the game fo
sergeinik [125]

Answer:

0.6517

Step-by-step explanation:

Given that in a certain game of chance, your chances of winning are 0.3.

We know that each game is independent of the other and hence probability of winning any game = 0.3 (constant)

Also there are only two outcomes

Let X be the number of games you win when you play 4 times

Then X is binomial with p = 0.3 and n =4

Required probability

= Probability that you win at most once

= P(X\leq 1)\\=P(X=0)+P(X=1)

We have as per binomial theorem

P(X=r) = nCr p^r (1-p)^{n-r}

Using the above the required prob

= 0.6517

Which equation correctly uses point (–2, –6) to write the equation of this line in point-slope form? Y – 6 = y minus 6 equals St
Tanya [424]

Answer:

Step-by-step explanation:

The standard way of writing equation of a line in a point-slope form is as given;

y - y0 = m(x-x0)

m is the slope of the line

(x0,y0) is a point on the line.

Given the point (-2,-6), in order to determine with of the equation that correctly uses the point, we will substitute the point into the formula and get the necessary equation.

y - y0 = m(x-x0)

y - (-6) = m(x-(-2))

y+6 = m(x+2)

Since we are not given the slope, let's assume the slope is 5/2

The equation becomes y+6 =5/2(x+2). Option D is correct

Select the prime number in each exercise <br> 37, 38, 39, 40, 42
olga nikolaevna [1]

Answer:

37 is prime number

Step-by-step explanation:

To prove whether a number is a prime number, first try dividing it by 2, and see if you get a whole number. If you do, it can't be a prime number. If you don't get a whole number, next try dividing it by prime numbers: 3, 5, 7, 11 (9 is divisible by 3) and so on, always dividing by a prime number
