Answer:
The probability is 1/6
Step-by-step explanation:
Firstly, we need to get the total number of coins
that would be the sum of all the coins present
We have this as;
8 + 10 + 4 + 2 = 24 coins
The number of nickels is 4
So the probability of selecting a nickel is the number of nickels divided by the total number of coins
We have this as;
4/24 = 1/6
Answer: B
Step-by-step explanation:
pi is greater than all of the numbers and there is no selection for pi being greater and
is 2.828 and so on which is greater than 4/3 which equals 1.333 and so on..
Answer:
<u>y = -x² + 4</u>
Step-by-step explanation:
The equation of the parabola in the vertex form is:
y = a (x-h)² + k
Where: (h,k) the coordinates of the vertex & a is a multiplier
The parabola has a vertex at ( 0,4 )
So, h = 0 , k = 4
∴ y = a (x-0)² + 4
∴ y = a x² + 4
The parabola passes through points ( 2,0 )
∴ 0 = a 2² + 4
∴ 4 a = -4 ⇒ a = -4/4 = -1
∴ y = -x² + 4
So, the equation of a parabola that has a vertex at ( 0,4 ) and passes through points ( 2,0 ) is <u>y = -x² + 4</u>
