Answer:

333 and 1000

Step-by-step explanation:

a]

The expected value of spinning the wheel is given by:

E(x)=2/9(200)+4/9(300)+2/9(400)+1/9(600)

E(x)=44 4/9+133 1/3+88 8/9+66 2/3

E(x)=333 1/3

b] The expected value of spinning the wheel thrice will be:

(expected value of spinning once)*(number of spins)

=333 1/3*3

=1000/3*3

=1000

A plant is 2 inches tall. In sunlight, the plant grows 1 inch each week. At the end of the 4th week, the plant is placed in a da
babunello [35]
I would label the x-axis with a scale 1-10 weeks and the y-axis with inches grown. The graph starts at 2inches because it’s the height of the plant. For the next 4 weeks there will be a growth of 1 inch a week (reaching 6) than the line stays at the height for 2 weeks until it gets sunlight again for 3 more weeks making it grown 3 more inches and repeats the process again.

After traveling for 4 hours and 1800 miles, an airplane begins a steady descent. When it begins descending, its altitude (height
andrey2020 [161]

Answer:

Part 1)  Descending Rate = -2,000 ft/min

Part 2)  Starting altitude value is 33,000 ft

Part 3)  The linear equation for the plane's altitude (y) as a function of time (x) is:  y=-2000\,\frac{ft}{min} \,x\,+\,33000\,ft

Part 4)  The information not used for the equation is that the plane was travelling for 4 hours to cover 1800 miles before starting the descent

Step-by-step explanation:

Part 1)

The rate at which the airplane descends is given by the difference between final and initial altitude (17,000 ft-33,000 ft) divided the elapsed time (8 minutes):

Descending\,\,Rate\,= \frac{17000-33000}{8} \,\,\frac{ft}{min}=\frac{-16000}{8} \,\,\frac{ft}{min}=-\,2000\,\,\frac{ft}{min}

Part 2)

When graphing the descent (that is the plane's altitude as a function of time), the starting value for the altitude should be 33,000 ft

Part 3)

We can build the equation of the plane's altitude as a function of time in slope y-intercept form y = m x + b

by noticing that the slope "m" stands for the rate of descent that we found in part 1), and then using the information that at time zero (when the plane starts its descent), its altitude is 33000 ft:

y=m\,x\,+\,b\\y=-2000\,\frac{ft}{min} \,x\,+\,b\\33000=-2000\,\frac{ft}{min} \,(0)\,+\,b\\33000=b

with this information about the intercept "b", we can write the final expression for the plane's altitude as a function of time during its descent as:

y=-2000\,\frac{ft}{min} \,x\,+\,33000\,ft

Part 4)

The information that was not used to write the descent equation was the initial details about how long the plane traveled (4 hours) and for 1800 miles.

Tasya [4]
If you think about how it works when cups are stacked. you will begin with the height of the cup plus the height of the lip you would then add just the heigt of the lips until you get to the height needed. so your answer should be 19 cups
