Answer:

see attached

Step-by-step explanation:

Based on 100 trials, we don't expect the experimental probability to deviate much from the theoretical probability. The scales on the attached graphs are hard to read, but you want to choose the graph that ...

has bars that total 100 in their length
has bars that are approximately .50, .25, .17, .08 in height, corresponding to the area fraction

We think the appropriate choice may be C, but we cannot tell for sure.

The mean amount of water in 5 containers is 620 ml the total amount of water in 4 q of the containers is 2750 what is the amount

EleoNora [17]

The correct answer is:

350 ml.

Explanation:

Let x be the amount in the fifth container.

The mean is found by adding all of the amounts together and dividing by the number of containers (in this problem, 5). We know that the total from the other 4 containers is 2750; add this to x, our unknown number. Then we divide by 5 to arrive at our answer of 620.

Algebraically,
 $\frac{2750+x}{5}=620$ 

To solve, multiply both sides by 5:
 $\frac{2750+x}{5}\times 5=620\times 5
\\
\\2750+x=3100$ 

Subtract 2750 from both sides:
2750+x-2750=3100-2750
x=350.

There are 350 ml in the fifth container.

A Ferrari drove 300 kilometers in one and a half hours. How fast was the car going?

irga5000 [103]

I'm assuming you mean how many mph when you refer to how fast the car was going.

So 300 km = 1.5 hrs

1.) Find the number of km per hour
Since we have the equation 300km = 1.5hr, we can just divide 1.5 (to isolate the number of hours) on both sides.

You should get 200 km = 1 hour

2.) Convert km to miles
To do this, you must know the conversion 1 km = 0.621371192 miles

So to convert 200 km to miles, just multiply 200 x 0.621371192.

You should get 124.274238.

That means the Ferrari drove at a pace of roughly 124 mph :)
