1. What is the theoretical probability that the family has two dogs or two cats?
gogolik [260]

let dogs be heads. Let cats be tails. A coin has two sides, in which you are flipping two of them. Note that there can be the possible outcomes  

h-h, h-t, t-h, t-t.  

How this affects the possibility of two dogs & two cats. Note that there are 1/2 a chance of getting those two (with the others being one of each), which means that out of 4 chances, 2 are allowed.  

2/4 = 1/2  

50% is your answer

Heads represents cats and tails represents dogs. There is two coins because we are checking the probability of two pets. You have to do the experiment to get your set of data, once you get your set of data, you will be able to divide it into the probability for cats or dogs. To change the simulation to generate data for 3 pets, simply add a new coin and category for the new pet.

Hope this helps you out!

What is the total surface area of the square pyramid?
pochemuha

Answer:

48

Step-by-step explanation:

The square pyramid has exactly the same four triangles.

In order to find the whole surface area, we must find the area of one of the triangles and multiply them by 4.

Surface area of square pyramid = \frac{bh}{2} * 4

Where we know that b = 4 and h = 6.

Substituting into the formula should give us the answer 48.

Write an equation that gives the proportional relationship of the graph.
viktelen [127]

The required equation is: y= 7x

Option C is correct.

Step-by-step explanation:

The proportional relationship can be found using the equation: y=k\,x

where x and y are the points and k is the constant of proportionality.

We need to find k.

From the graph given, we can locate points x and y:

x=5, y= 35 then k would be:

y=kx\\k=y/x\\k=35/5\\k=7

x=10, y=70 then k would be:

y=kx\\k=y/x\\k=70/10\\k=7

For each values of x and y, the constant of proportionality k is 7

So, the required equation is: y= 7x

Option C is correct.

The equation y - 3x - 5 = 0 when written in slope-intercept form is:
quester [9]

Answer:

y = 3x + 5

Step-by-step explanation:

The zero seems to be a place holder to mess you up. Just ignore that it doesn't do anything. Add -3x and -5 to the both sides to create y = 3x + 5
