Answer:

Histogram C is the correct option.

Step-by-step explanation:

From the given data in the question, we will try to draw the histogram in terms of height of the students and frequency.

Height of the students                  Frequency

115-120                                               4

120-125                                              5

125-130                                              3

130-135                                              2

135-140                                              4

By this table we can analyze the Histogram C will be the answer.

What radius of a circle is required to inscribe a regular hexagon with an area of 166.28 in2 and an apothem of 6.928 in?
Lunna [17]
If you want to inscribe a polygon inside a circle, you have a formula that doesn't have to use the apothem. The formula is:

A = (nr²/2)sin(360/n)

Since the polygon is a hexagon, it has 6 sides. Thus, n = 6. Knowing the area, we can determine the radius of the circle, r.

166.28 = (6r²/2)sin(360/6)
r = 8 inches

Thus, the radius of the circle is 8 inches.

A television network is deciding whether or not to give its newest television show a spot during prime viewing time at night. If
Alinara [238K]

Answer:

Test statistic  z= 1.708

Step-by-step explanation:

given that a  television network is deciding whether or not to give its newest television show a spot during prime viewing time at night. If this is to happen, it will have to move one of its most viewed shows to another slot.

Sample size n = 827

Sample proportion p = \frac{438}{827} \\=0.5297

H_0: p =0.5\\H_a: p >0.5

(right tailed test)

This is because they would be interested if more than half viewers are ready for the change

Test statistic = Z = p difference/std error

p difference = 0.0297

Std error =\sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.5*0.5}{827} } \\=0.0174

Z =1.708

p valu e= 0.9562

Since p >0.05 we fail to reject H0

Test statistic  z= 1.708

These 20 ages of children on a school bus are in order from least to greatest. 5, 5, 5, 6, 6, 7, 7, 8, 9, 10, 10, 11, 12, 12, 12
umka2103 [35]

Answer:

the interquartile range is the Q3-Q1 where Q3 is 75th percentile and Q1 is the 25th percentile.

so the total count is 20 so 25 percentile is 25% of 20 =5 and 75th percentile is 75% of 20 = 15 and since the number are already arranged in order we just pick the 15th number-5th number   thus, our answer is

                              12-6 = 6
