C=(3.14)(15)
you multiply and get 47.1
Let b= length and a=width
Area= a*b and the problem said b=2a+3 (the length is 3ft more than double the width)
Replace b into Area formula:
Area= a*(2a+3) and we know that Area=77ft from the problem, so:
77=2a^2+3a now order and equal to zero:
2a^2+3a=77 now solve this with quadratic formula and you will get so values for a: -7ft and 5.5ft as you know the dimensions could not be negative so the correct answer for "a" side is 5.5ft, for getting the b side you haeve to replace a=5.5 into b=2a+3 and you will get b=2*5.5+3= 14ft.
Finished.
2 tables. Table 1 is titled Population data with entries 2, 4, 8, 5, 1, 1, 10, 5, 4, 2, 3, 3. Table 2 is titled Sample data with
alekssr [168]
Answer: //The mean of the population is 4
//The mean of the population is 3.25
//The difference between the mean of the sample and the mean of the population is 0.75
Step-by-step explanation: EGDEUNITY
The conversion is
So
We're given the fairly unusual
It's fairly unusual because usually an angle is given in degrees or radians, and typically the radians are a fraction times pi. We'll assume radians.
Ah, there's our .75. The approximate answer is
Third choice.
The exact answer is
also a line through the origin.
