Answer: The probability is zero.
Step-by-step explanation:
The labels on the 4 cards are 1, 3, 5 and 7. Because the cards are equal, the probability of dragging at random each one of them is equal to 1/4 = 0.25.
Now, the probability that Tim selects a card labeled with a 4 is equal to the number of cards labeled with a 4, divided the total number of cards.
We do not have cards labeled with a 4, so the probability is:
p = 0/4 = 0
because we do not have any card labeled with a 4, the probability of selecting one at random is equal to zero.
Answer:
True
Step-by-step explanation:
2x+5=x-3 is (-8)
This is the correct answer
Answer:
x=1, y=-1. (1, -1).
Step-by-step explanation:
2x+3y=-1
3x+5y=-2
-----------------
3(2x+3y)=3(-1)
-2(3x+5y)=-2(-2)
-------------------------
6x+9y=-3
-6x-10y=4
--------------
-y=1
y=-1
2x+3(-1)=-1
2x-3=-1
2x=-1+3
2x=2
x=2/2
x=1
Answer:
x = 7.2
Step-by-step explanation:
Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x and 1.7.
Now. the distance between - 3.8 and x will be (x + 3.8) and the distance between x and 1.7 will be (x - 1.7) {Since x is a positive number}
(Assuming x is greater than 1.7}
Given that, x + 3.8 = 2(x - 1.7)
⇒ x + 3.8 = 2x - 3.4
⇒ x = 7.2 (Answer)
