Answer:
P of white: 0.26
P of green: 0.39
Step-by-step explanation:
Assume the probability of a white pin is p.
Then the probability of a green pin is (3/2)p because their ratio is 3:2.
The sum of the probabilities must be 1.
0.1+(3/2)p+0.25+p=1
(5/2)p+0.35=1
(5/2)p=0.65
p=(2/5)(0.65)=0.26
(3/2)p=0.39
The distance covered by the hare and the tortoise in t seconds are 8t and 5t respectively. (Simple Speed-Distance-Time relation)
The tortoise gets a 510m headstart so at t=0 is 1490m.
The functions representing the distance of both of them from the finish line is,
F(x)=2000-8t,. for hare
G(x)=1490-5t,. for tortoise
The x-intercept is the point where the graph cuts the x-axis, and the y-intercept is the point where the graph cuts the y-axis.
The x-axis is the line y = 0 and the y-axis is the line x = 0. To find the intercept between each axis and our graph, we just need to evaluate our function at x = 0 and y = 0.
Calculating the x-intercept, we have

The x-intercept is (8, 0).
Calculating the y-intercept, we have

The y-intercept is (0, -2).
Answer:
r= 0
r= 1
b= -3
x= -3
Step-by-step explanation:
4r-8r=0
-4r=0
r=0
-15=-8r-7r
-15= -15r
r=1
3b+7-1=-3
3b= -3-7+1
3b= -9
b= -9/3
b=-3
3x+1-6x=7
-3x= 7-1
-3x= 6
x= -6/3
x= -3
10 people because all the sisters have the same brother so 7+1+2.
