Answer:
25%
Step-by-step explanation:
There are 4 cards. Each one is a different number.
Only one card is a 9.
p(9) = 1/4 = 0.25 = 25%
Could you finish the problem and tell us what the problem is
Answer:
the answer is 54.7
Step-by-step explanation:
82.6 - 27.9 = 54 7
35×.2= 7 dollars is being taken away from the sale.
35-7= 28 dollars which is the new cost.
28×.06=1.68
28+1.68=29.68 final cost of jeans
or you can do 28×1.06= 29.68 final cost of jeans.
Answer: Yes, y does vary directly with x.
Constant of variation = 1/4
The function rule is y = (1/4)x
=========================================================
Explanation:
Let's assume that y does vary directly with x.
If that's the case, then we have an equation in the form y = kx, where k is the constant of variation.
Solving for k gets us k = y/x
For each row, divide the y value over the x value
- row one: k = y/x = 14/56 = 0.25
- row two: k = y/x = 20/80 = 0.25
- row three: k = y/x = 22/88 = 0.25
Each row yields the value k = 0.25 and it fully confirms y does vary directly with x.
So y = kx becomes y = 0.25x as the function rule, which is equivalent to y = (1/4)x
