Each of two urns contains green balls and red balls. Urn 1 contains 10 green balls and 8 red balls. Urn 2 contains 3 green balls and 10 red balls. If a ball is drawn from each urn, what is P(red and red)?
Answers
hence,P(urn-1)=8/18,p(urn-2)=10/13
WHAT IS PROBABILITY?
Probability is number of favorable outcomes by total no. of outcomes
How to calculate ?
No. of favorable outcomes / total no. of outcomes.
Given urn-1- 10 green balls and 8 balls .
and urn -2 - 3 green balls and 1- red balls .
ball is taken out from both the baxes
probability of red ball= p(urn1
P(urn-1)=8/18
p(urn-2)=10/13

Answer:
Given : BRDG is a kite that is inscribed in a circle,
With BR = RD and BG = DG
To prove : RG is a diameter
Proof:
Since, RG is the major diagonal of the kite BRDG,
By the property of kite,
∠ RBG = ∠ RDG
Also, BRDG is a cyclic quadrilateral,
Therefore, By the property of cyclic quadrilateral,
∠ RBG + ∠ RDG = 180°
⇒ ∠ RBG + ∠ RBG = 180°
⇒ 2∠ RBG = 180°
⇒ ∠ RBG = 90°
⇒ ∠ RDG = 90°
Since, Angle subtended by a diameter or semicircle on any point of circle is right angle.
⇒ RG is the diameter of the circle.
Hence, proved.

Answer:
A: The x-intercept is x = -5 and the graph approaches a vertical asymptote at x = -6
Step-by-step explanation:
The diagram shows translated to the left graph of the logarithmic function.
This graph intersects the x-axis at point x = -5, hence the x-intercept is at x = -5.
This graph approaches to the vertical line. The line passes through the point (-6,0), so the equation of this vertical line is x = -6.
Therefore, correct option is A: The x-intercept is x = -5 and the graph approaches a vertical asymptote at x = -6

To write the fraction 7/10 as a sum of fractions three different ways, you can use a common denominator, multiples of the denominator, or equivalent fractions.
Explanation:
To write the fraction 7/10 as a sum of fractions three different ways, we can use different denominators. Here are three ways:
- Using a common denominator: Multiply the numerator and denominator of 7/10 by 3/3 to get 21/30. Then, express 21/30 as the sum of three fractions with different numerators: 7/30 + 7/30 + 7/30.
- Using multiples of the denominator: Express 7/10 as the sum of fractions with denominators that are multiples of 10, such as 20, 30, and 40. So, 7/10 can be written as 14/20 + 21/30 + 28/40.
- Using equivalent fractions: Find equivalent fractions of 7/10 with different denominators, such as 14/20, 21/30, and 28/40. Then, express 7/10 as the sum of these equivalent fractions.
