Answer:
First choice:
- <em><u>Most of the data in each plot are greater than 48.</u></em>
Explanation:
1. Boy's Heights.
Using the information you can create a frequency table:
Heigth Frequency
40 0
41 1
44 3
46 3
48 2
50 3
52 4
54 4
56 0
58 0
60 0
======
20 boys
2. Girl's Heights.
Similarly, create your frequency table:
Height Frequency
40 0
41 0
42 0
44 2
46 3
48 1
50 3
52 4
54 3
56 4
58 0
60 0
======
20 girls
<em>Which is a true statement for most of the data in each plot?</em>
<u><em>Most of the data in each plot are greater than 48.</em></u>
- Count the dots or add the frequencies from the tables.
- For boys, the frequency of points greater than 48 is: 3 + 4 + 4 = 11 which is more than half (there are 20 dots).
- For girls, the frequency of points greater than 48 is: 3 + 4 + 3 + 4 = 14, which is also more than half.
Hence, it is correct that most fo the data in each plot are greater than 48.
The correct answer would be option A. h = 9n
Answers:
x = 6 and P = 128
=================================================================
Explanation:
The tangents CT and CU are equal to each other. The rule is that tangent segments that meet at a common point are the same length.
Let's solve for x
CT = CU
3x = 18
x = 18/3
x = 6
Because CT = 18, this makes BC = BT+TC = 12+18 = 30
---------------------------
For similar reasoning as mentioned earlier, we can say tangents BT and BV are the same length. This means BV = 12.
Segment CD = 52 and CU = 18, which makes UD = CD-CU = 52-18 = 34
From there, we can say segment DV = 34 also. This leads to BD = BV+VD = 12+34 = 46
Triangle BCD has the three sides
The perimeter is
P = sum of the three sides
P = (side1)+(side2)+(side3)
P = BC + CD + BD
P = 30+52+46
P = 82+46
P = 128
D
19/50 multiply 2 on numerator and denominator it becomes 38/100
38/100 = 0.38 since 38/100 is 38 divide by 100 which is 0.38
This is a geometric sequence of the form:
a(n)=(x+3)(-2x)^(n-1) because each term is -2x times the previous term...so
a(8)=(x+3)(-128x^7)
a(8)=-128x^8-384x^7
