2. The box plots summarize the number of students at the fall and spring dances. Which statement best describes the data represented in the box plots?
Answer:
See Explanation
Step-by-step explanation:
The question has missing parameters, as the box plot is not given.
So, I will answer the question using the attached box plot.
Basically, the box plot summarizes 5 data which are:
Minimum, Lower quartile, the Median, the Upper quartile and the Range
So, the summary is as follows:
The first dot on the box plot represents the minimum
[tex]Minimum = 2[/tex]
The first line represents the lower quartile
[tex]Q_1 = 3[/tex]
The mid-line represents the median:
[tex]Q_2 = 6[/tex]
The third line represents the upper quartile:
[tex]Q_3 = 8[/tex]
The last dot represents the maximum
[tex]Maximum = 12[/tex]
From the above data, we can also calculate the range.
[tex]Range = Maximum - Minimum[/tex]
[tex]Range = 12 - 2[/tex]
[tex]Range = 10[/tex]

What is sampling?It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a group containing elements of a population. A sample has to be representative of the population, that is, it has to involve all segments of the population.
In this problem, a group of 150 businesses(sample) is taken from the telephone listings(all the businesses in the listings is the population), hence option C is correct.

The equation h = -16t 2+ 53x + 8 gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked. What is the maximum height the football reaches?
Answer: The maximum height the football reaches = 51.89 feet.
Step-by-step explanation:
Given: The equation [tex]h = -16t^2+ 53t + 8[/tex] gives the height h, in feet, of a football as a function of time t, in seconds, after it is kicked.
Differentiate the given equation, we get
[tex]h'=-(2)16t+53=-32t+53[/tex] (i)
Put [tex]h'=0[/tex]
[tex]\Rightarrow\ -32t+53=0\\\\\Rightarrow\ t=\dfrac{53}{32}\approx1.65625[/tex]
Differentiate (i) w.r.t. t, we get
[tex]h''=-32[/tex] < 0 i.e. h is maximum at t= 1.65625
The value of h at t= 1.65625 will be [tex]-16(1.65625)^2+53(1.65625)+8=51.890625\approx51.89\text{ feet}[/tex]
Hence, the maximum height the football reaches = 51.89 feet.

Suppose it takes 2 1/2 h to drive from your house to the lake at 48 mi/h. How long will your return trip take at 40 mi/h?
Answer
The distance from the house to the lake is (2.5 hr)*(48 mi/hr) = 120 miles. The rerurn trip would take (120 mi)/(40 mi/hr) = 3 hours. Distance equals rate times time, so the distance to the lake is 2 1/2 hours times 48 miles per hour.

Step-by-step explanation:
Use the substitution property of equality.
C = s -5
D = s -8
Then the value of your expression is ...
C +2D = (s -5) +2(s -8)

Luca eats 3/6 of his submarine sandwich. Riley eats 5/6 of his submarine sandwich. Riley said he ate 2/6 more than Luca. Is he correct, if the sandwich sizes are different.
Answer:
Riley is correct
Step-by-step explanation:
Luca eats 3/6 of his submarine sandwich. Riley eats 5/6 of his submarine sandwich. Riley said he ate 2/6 more than Luca.
To find out the fraction of how much more Riley ate than Luca, we carry out Subtraction operation
= Fraction of what Riley ate - Fraction of what Luca ate
= 5/6 - 3/6
Lowe's Common Denominator = 6
= 5 - 3/6
= 2/6
Therefore, Riley is correct
