3 0

Answer:

The answer could be 0 or 1 out of 4, because choosing a card at first and not putting it back, then picking a second card at random, it would likely be one in zero attempts to pick 3 again but otherwise that it could be 1 out of 4 because it could be possible picking 3 at the first try.

the table below represents the displacement of a turtle from its nest as a function of time.Part A. What is the y intercept of t

hoa [83]

Part A.

Y intercept is the coordinate (0,y), when the function has an x value of 0, it is the y intercept.

In this case:

(0,5) =

y intercept = 5

IT tells about the turtle that it starts at a nest displacement of 5 miles.

Part B

The average rate of change represents the speed .

x1=1 ,y1=27

x2=4 ,y2=93

We have to calculate the slope if the function:

$\text{slope}=\text{ }\frac{y2-y1}{x2-x1}$

Replace:

$\text{slope}=\frac{93-27}{4-1}\text{ = }\frac{66}{3}=22$

Part C.

speed = distance /time

time= distance / speed

time= 225 / 22 = 10.22 hours

The domain will be

0< x ≤ 10.22

Daniel [21]

Area of a rectangle = Length * Width
Area = 60cm^2
Length = 4
Width = GH = ? = x

60 = 4*x
solve for x
60/4 = x
x = 15

GH is 15cm
