Answer:

  • 1.71 min

Step-by-step explanation:

Alan draws a picture in 3 minute

<u>In one minute he draws:</u>

  • 1/3 of the picture

<u>Similarly, Beatrice draws </u>

  • 1/4 of the picture in 1 minute

<u>Together the draw in one minute:</u>

  • 1/3+1/4 = 7/12 of the picture

<u>To complete the picture they need:</u>

  • 1:7/12 = 12/7 min or 1  5/7 min  or 1.71 min

Which set of ordered pairs could be generated by an exponential function?
klemol [59]

Answer: Third option.

Step-by-step explanation:

By definition, Exponential functions have the following form:

y = ab^x

Where "b" is the base (b > 0 and b\neq 1), "a" is a coefficient (a\neq 0) and "x" is the exponent.

 It is importat to remember that the "Zero exponent rule" states that  any base with an exponent of 0 is equal to 1.

Then, for an input value 0 (x=0) the output value (value of "y") of the set of ordered pairs that could be generated by an exponential function must be 1 (y=1).

You can observe in the Third option shown in the image that when x=0, y=1

 Therefore, the set of ordered pairs that could be generated by an exponential function is the set shown in the Third option.

sweet [91]

Answer:

<h2> Driver B has the fastest race time</h2>

Step-by-step explanation:

From the options presented, driver B has the fastest typical race time because he recorded the smallest time taken to complete an individual race.

Also from the standard deviation given (3.96) for driver B, it shows that the individual time spread from the standard deviation is minimal and that the driver maintained a fairly consistent time of race throughout the racing period.
