1/3(5)=5/15
the numerator is 1, and since the other numerator is 5, you just need to multiply 1/3 by 5 which gives you 5/15
Answer:
(x + 4)² + (y + 5)² = 73
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
here (h, k) = (- 4, - 5), thus
(x - (- 4))² + (y - (- 5))² = r², that is
(x + 4)² + (y + 5)² = r²
The radius is the distance from the centre to a point on the circle.
Calculate r using the distance formula
r = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (4, - 2)
r =
=
= = ⇒ r² = 73, thus
(x + 4)² + (y + 5)² = 73 ← equation of circle
Given,
Diameter of circle=15cm
so, radius= D/2= 15/2
we know that circumference=perimeter
2πr= 2×22/7×15/2=47.1428cm
Answer as a fraction = 1/25
Answer in decimal form = 0.04
Answer in percent form = 4%
Explanation:
There are 5*5 = 25 different outcomes, of which only one outcome has 5,5. The probability of picking two 5s is 1/25 = 0.04 = 4%
