P(getting odd number)  = 3/6 = 1/2     ( as there are 3 odds and 3 evens on a die).

P(head) = 1/2 

these are multiplied as the 2 events are independent :-  
Answer is 1/2 * 1/2 = 1/4

A certain backpack costs $22, and there is 4% sales tax. What is one way to determine what the amount of sales tax will be? Sele
Mademuasel [1]

Answer:

$0.88

Step-by-step explanation:

cost per 1% = 22 ÷ 100 = 0.22

⇒ cost of 4% = 4 x 0.22 = 0.88

Or

4% = 4/100 = 0.04

⇒ 4% of 22 = 0.04 x 22 = 0.88

(Algebra II) Standard Form of a Quadratic Function - I'm having trouble with two questions on this quiz? Please don't just give
anastassius [24]
1.
the x value of the vertex in form
ax^2+bx+c=y
is
-b/2a
so

-2x^2+8x-18
x value of vertex is
-8/(2*-2)=-8/-4=2

plug it in to get y value
-2(2)^2+8(2)-18
-2(4)+16-18
-8-2
-10

vertex is at (2,-10)
or you could complete the square to get into y=a(x-h)^2+k, where the vertex is (h,k)
so as follows
y=(-2x^2+8x)-18
y=-2(x^2-4x)-18
y=-2(x^2-4x+4-4)-18
y=-2((x-2)^2-4)-18
y=-2(x-2)^2+8-18
y=-2(x-2)^2-10
vertex is (2,-10)

Juli2301 [7.4K]

Answer:

  B, C, F

Step-by-step explanation:

3/4 is 3 times 1/4, so the number of walls Dan can paint is 3 times the number of cans Dan uses.

A. 1/2 can will paint 3/2 walls, not 2.

B. 1 can will paint 3 walls — true

C. 5/3 cans will paint 5 walls — true

D. 2 cans will paint 6 walls, not 8.

E. 5/2 cans will paint 15/2 = 7 1/2 walls, not 10.

F. 11/3 cans will paint 11 walls — true
