its spends 2.5 hours going 35 miles per hour. so the answer is 2.5 because 35 miles as you said goes 2.5 hours
Answer:
x= -8 , y = 5
x= 25/4 , y = 1/4
Step-by-step explanation:
substitute first eqn into the second eqn:
(7 - 3y)^2 -y^2 = 39
49 - 42y + 9y^2 - y^2 = 39
8y^2 - 42y +10 =0
4y^2 - 21y + 5 = 0
(4y-1) (y-5) = 0
y= 1/4 , 5
when y=1/4
x = 7- 3/4
=25/4
when y= 5
x = 7- 15
= -8
The function is continuous
Answer:
33
Step-by-step explanation:
Answer:
The value is
Step-by-step explanation:
From question we are told that
The number of types of marbles present jar is n = 3
Generally the probability of drawing a green marble is
Generally the probability of drawing a marble that is not green is
From the question we are told that there will be continuous drawing of marbles from the jar (in such a way that after each marble is drawn it is being replaced) until a green marble drawn
Let m be the number of times marbles has been drawn when a green marble was gotten
it then means that for m - 1 times the marbles where drawn a green marble was not obtain.
Generally the probability drawing m times is mathematically is mathematically represented as
=>
