Answer:
1/64
Step-by-step explanation:
Each of the questions has 4 choices, making the chance to get the correct answer 1/4. So, to get 3 questions correct, you can use 1/4^3 to find the probability. So, the answer is 1/64.
Answer:
$16
Step-by-step explanation:
Looking at the Price for 5 Items (10 dollars), That means the Price Per Item Is 2 dollars. Now we know the Cost per Item, We need to multiply the Cost per item by 8 (2*8) making it 16.
A deck has 52 cards
A deck has 25 black cards.
A deck has 4 "4" cards but 2 of them are black, therefore 2 red
P(black or 4) = (25 + 2) / 52 = 27/52
The equestion is
2x^2-5x-12=0
we can either try to factor, or use quadratic formula
trial and errot
(x-4)(2x+3)=0
set to zero
x-4=0
x=4
2x+3=0
2x=-3
x=-3/2
x=-3/2 or 4
Answer:
The linear function is 
.
Step-by-step explanation:
A linear function is given by the formula,
, where m is the slope and c is the y intercept of function.
The following two points lie on the graph; (0,-1) and (3,-10)
Inserting this two points we get,
,
solving this two equations we get,
m = -3 and c= -1
Thus, the linear function is given by,
