Khushali selects three different numbers from the set

Maslowich

Answer:

The sample space for given condition is

(1,8),(2,8),(3,8),(4,8),(5,8),(6,8),(7,8)

(1,7),(2,7),(3,7),(4,7),(5,7),(6,7)

(1,6),(2,6),(3,6),(4,6),(5,6)

(1,5),(2,5),(3,5),(4,5)

(1,4),(2,4),(3,4)

(1,3),(2,3)

(1,2)

Number of sample space is 28.

Number of sample space where the sum of two numbers is more than 13 is 2((6,8),(7,8)). Therefore the probability is

The point P is the reflection of the point (-7, 5) in the line 5x - 3y = 18.

Sonbull [250]

Answer:

(13,-7)

Step-by-step explanation:

$5x-3y=18 \\ \\ -5x+3y=-18 \\ \\ 3y=5x-18 \\ \\ y=\frac{5}{3}x-6$

The slope of the given line is 5/3. Perpendicular lines have slopes that are negative reciprocals of each other, so we need to find the line with slope -3/5 through P.

$y-5=-\frac{3}{5}(x+7) \\ \\ y-5=-\frac{3}{5}x-\frac{21}{5} \\ \\ y=-\frac{3}{5}x+\frac{4}{5}$

Finding where the lines intersect,

$-\frac{3}{5}x+\frac{4}{5}=\frac{5}{3}x-6 \\ \\ -9x+12=25x-90 \\ \\ 34x=102 \\ \\ x=3 \implies y=-1$

The point where the line of reflection and the perpendicular drawn to it through the point being reflected is the midpoint of the preimage and the image.

Let the coordinates of the image be (a,b). Then, by the midpoint formula,

$\frac{-7+a}{2}=3 \implies -7+a=6 \implies a=13 \\ \\ \frac{5+b}{2}=-1 \implies 5+b=-2 \implies b=-7$

Therefore, P has coordinates (13, -7).

Canh square roots be rational numbers ?

Juliette [100K]

When the square root of a number is a whole number, this number is called a perfect square. ... Not all square roots are whole numbers. Many square roots are irrational numbers, meaning there is no rational number equivalent
