<span>Experimental Probability is the ratio of the number of times an event occurs to the total number of trials.

Given that </span><span>Cole rolls a number cube multiple times and records the data in the table below. At the end of the experiment, he counts that he has rolled 190 fours.

From the table, we see that the total number of trials is 1,000 and there are 190 fours.

Therefore, the experimental probability of rolling a four, based on Cole’s experiment is given by 190 / 1,000 = 0.19 = 0.190 to the nearest thousandth.</span>

Answer:

B. 0.190

I took a quiz, thats how I know that B is the answer, since the question doesn't say that 0.190 is B.  

Hope I helped!

A plane flying horizontally at an altitude of "1" mi and a speed of "430" mi/h passes directly over a radar station. Find the ra
Anika [276]

Answer:

The rate at which the distance from the plane to the station is increasing when it is 2 mi away from the station is 372 mi/h.

Step-by-step explanation:

Given information:

A plane flying horizontally at an altitude of "1" mi and a speed of "430" mi/h passes directly over a radar station.

z=1

\frac{dx}{dt}=430

We need to find the rate at which the distance from the plane to the station is increasing when it is 2 mi away from the station.

y=2

According to Pythagoras

hypotenuse^2=base^2+perpendicular^2

y^2=x^2+1^2

y^2=x^2+1               .... (1)

Put z=1 and y=2, to find the value of x.

2^2=x^2+1^2

4=x^2+1

4-1=x^2

3=x^2

Taking square root both sides.

\sqrt{3}=x

Differentiate equation (1) with respect to t.

2y\frac{dy}{dt}=2x\frac{dx}{dt}+0

Divide both sides by 2.

y\frac{dy}{dt}=x\frac{dx}{dt}

Put x=\sqrt{3}, y=2, \frac{dx}{dt}=430 in the above equation.

2\frac{dy}{dt}=\sqrt{3}(430)

Divide both sides by 2.

\frac{dy}{dt}=\frac{\sqrt{3}(430)}{2}

\frac{dy}{dt}=372.390923627

\frac{dy}{dt}\approx 372

Therefore the rate at which the distance from the plane to the station is increasing when it is 2 mi away from the station is 372 mi/h.

I AM SO COMFUSED f- 1.8 = 11.2
balandron [24]

Answer:

Your answer for F will be 13.

Step-by-step explanation:

Take 11.2 and add it to 1.8, and you will get 13 and 13 will be the variable (f). So, f (13) - 1.8 = 11.2

Hope this helps! :D
