Answer:
The value is placed in system of equation is -10.
Step-by-step explanation:
Given : System of equations and
To find : Which value when placed in the box (?) would result in system of equations which infinitely many solutions ?
Solution :
For a system of equations to have infinitely many solutions,
The equations have to be linearly dependent i.e. one of the equations is a multiple of the other equation.
In the given system of equations,
The second equation have to be a multiple of the first equation.
Re-write equation 1 as
The second equation is the first equation multiplied by 2,
i.e.
On comparing the missing term is -10.
Therefore, the value is placed in system of equation is -10.
2/5 = 0.40
so 2/5 is LESS THEN 0.44
Answer: a)
b)
c)
d)
Step-by-step explanation:
Formula for probability =
The total number of cards in a deck = 52
a) Number of cards having queen =4
Then the probability that a queen is drawn =
c) Number of cards having King= 4
Then , the number of cards having a queen or king =4+4=8
Then the probability that a king or queen is drawn =
c) Number of cards having heart = 13
Then the probability that a heart is drawn =
d) Number of red cards = 26
Then the probability that a red card is drawn =
because if u pick a grape that was 25% chance and then pick another grape that is 1/8
The common ratio in the geometric sequences 2
