Answer:

1400 ft2

Step-by-step explanation:

if 280 ft2 comes from 4/5 of 1 gallon of paint, then do 280 x 4, because their are 4 gallons of paint. after you x that it will be 1120 ft2. but the extra 1/5 paint from all 4 of the gallons comes out to 4/5 so add 280 ft2 to that 1120 ft2.

it comes out to 1400 ft2.

During with interval was the bicyclists speed the greatest?
Fudgin [204]

check the picture below.

namely, which of those intervals has the steepest slope, recall slope = average rate of change.

now, from the picture, notice, those two there are the steepest, the other three are leaning too much to the "ground".

so, from those two, which is the steepest anyway?  let's check their slope.


\bf \stackrel{\textit{from the 6th to the 8th hour}}{(\stackrel{x_1}{6}~,~\stackrel{y_1}{104})\qquad (\stackrel{x_2}{8}~,~\stackrel{y_2}{146})} \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{146-104}{8-2}\implies \cfrac{42}{2}\implies 21~~\bigotimes \\\\[-0.35em] \rule{34em}{0.25pt}

\bf \stackrel{\textit{from the 1st to the 2nd hour}}{(\stackrel{x_1}{1}~,~\stackrel{y_1}{12})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{34})} \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{34-12}{2-1}\implies \cfrac{22}{1}\implies 22~~\checkmark

If you flip three fair coins, what is the probability that you'll get a tail on the first flip, a head on the second flip, and a
kodGreya [7K]

Answer:

<em>12.5%</em>

Step-by-step explanation:

<u>Probabilities</u>

When flipping three fair coins, we can get the following events, being H=Heads, T=Tails

\Omega=\{HHH,HHT,HTH,HTT,THH,THT,TTH,TTT\}

We are looking for the probability of only one specific outcome: THT. The probability to get exactly that combination one out of 8 possible results, that is

\displaystyle P=\frac{1}{8}=0.125

The probability to get a tail on the first flip, a head on the second flip, and another tail on the third flip is 12.5%
