Answer:

1/12 or 8.33% is the probability

Step-by-step explanation:

Assuming the number cube has 6 sides there is 1/6 chance of getting a 3 and a 1/2 chance of getting tails when flipping a coin. Multiplying 1/6 by 2 to get 1/12.

Julie keeps rabbits and hamsters as pets she has four rabbits and an odd number of hamsters she has more hamsters than rabbits t

son4ous [18]

Answer:

H is greater than 4, less than 6, and is odd. H, therefore, must be 5.

Step-by-step explanation:

Let's write down what we know:

Julie keeps Rabbits ("R") and Hamsters ("H") as pets.

R=4

She has more H than R, so:

H>4

and H is odd.

The total of R and H is less than 10, so

R+H<10

we can substitute in for R:

4+H<10

and now we can solve for H:

H<10−4=6

So we know that H is greater than 4, less than 6, and is odd. H, therefore, must be 5.

If x = 8 units, y = 3 units, and h = 10 units, find the area of the trapezoid shown above using decomposition.

kondaur [170]

If by decomposition you mean breaking it ino parts then

break it itno 2 triangles and 1 rectangle

left to right

triangle with base y and height h
h=10
y=3
area of traignel=1/2bh
aera=1/2(10)(3)
area=5(3)
area=15

rectangel of legnth x and height h
area=legnth timwe width
x=8
h=10
area=8 times 10
aera=80

last triangle
should be same as other sinces same base (y) and same height (h)
15

add
15+80+15=120

The graph of a linear equation passes through three of these points: (0,5), (2, 2), (3, 1), and (4.-1).

sdas [7]

Answer:

(3, 1)

Step-by-step explanation:

plotting these points on a graph, while (3, 1) may look like it's on the line, it is the only point that would involve changing the slope of the line, so that point cannot be on the line.
