It is an arithmetic progression. Note the general rule for AP sequences:

a(n) = a(1) + (n - 1)d
a(1) = 12a (first term)
d = 3a (common difference)

General rule: a(n) = 12a + (n - 1)*3a

find the equation of a circle concentric with the circle x^2+y^2-2x-10y+1=0 passing through the point (2,-3)​
Natalija [7]

Answer:

Step-by-step explanation:

x²+y²-2x-10y+1=0

compare with x²+y²+2gx+2fy+c=0

center is (-g,-f)

radius=√(g²+f²-c)

2g=-2

g=-1

2f=-10

f=-5

radius=(1,5)

c=1

let eq. of circle be x²+y²-2x-10y+c=0

∵ it passes through (2,-3)

2²+(-3)²-2(2)-10(-3)+c=0

4+9-4+30+c=0

c=-39

eq. of circle is is x²+y²-2x-10y-39=0

Any questions 1-4 help me please
ASHA 777 [7]
For Q2 it is just a simple matter of using a tree diagram for each possible outcome. So there are 4 black balls (B) and 2 white (W) and by using a tree diagram of the possible outcomes it comes to a 3 out of 5 points go to player 1 if B was drawn first and 2 go to player 2. If W was drawn first though, then player 1 gets 1 out of 5 points and 4 goes to player 2 and if you add up the probabilities at the end it comes to player 1 having a 14 out of 30 chance and player 2 having a 16 out of 30 chance therefore player 2 would have a better chance at winning and it isn't a fair game

Agata [3.3K]

Answer:

Ratio as a fraction in simplest form is, \frac{\text{17 correct}}{\text{3 incorrect}}

Step-by-step explanation:

Ratio defined as the relationship between the quantities of something i.e,

a: b = \frac{a}{b}

Given: 51 correct : 9 incorrect

By definition of ratio:

51 correct : 9 incorrect = \frac{\text{51 correct}}{\text{9 incorrect}}

Divide both numerator and denominator by 3 we get;

\frac{\text{17 correct}}{\text{3 incorrect}}

then

The ratio as a fraction in simplest form  is, 17 correct : 3 incorrect or \frac{\text{17 correct}}{\text{3 incorrect}}
