Since there are 3 "2's" and 8 total options, the probability is 3/8 or C.
The kilogram of grass eaten by the cow is 7kg and the kilogram of grass eaten by the horse is 6kg.
<h3>The two simultaneous equations that can be derived from the question:</h3>
9h + 45c = 369 equation 1
4h = 3c + 3
4h - 3c = 3 equation 2
Where:
c = kg eaten by cows
h = kg eaten by horses
<h3>What is the value of h?</h3>
In order to determine the value of h, multiply equation 2 by 15
60h - 45c = 45 equation 3
Subtract equation 3 from equation 1
69h = 414
h = 6kg
<h3>
What is the value of c?</h3>
Substitute for c in equation 2
4(6) - 3c = 3
24 - 3c = 3
21 = 3c
c = 7

Answer:
x=5
AOB = 8
BOC = 13
AOC = 21
Step-by-step explanation:
<em>Angle AOB and Angle BOC is equal to Angle AOC.</em>
AOB = x+3
BOC = 4x-7
AOC= 2x+11
AOB + BOC = AOC
x+3+4x-7 = 2x+11
5x-4 = 2x+11
3x = 15
x = 5
Therefore, the value of x is 5.
<em>Angle AOB = x+3</em>
AOB = 5+3
AOB = 8
<em>Angle BOC = 4x-7</em>
BOC = 4(5)-7
BOC = 13
<em>Angle AOC = 2x+11</em>
AOC = 2(5)+11
AOC = 21

The box plot is not symmetrical for either data set.
<h3>What is Quartile?</h3>
Quartiles divide the data values into four parts; the first quartile is the 25th percentile, the second quartile is the 50th percentile (also the median), and the third quartile is the 75th percentile.
Firstly, order the two data set from smallest to largest as shown in diagram below
The value of median, Q2 is the 5th value of both set
The value of Q1 and Q3 is the first and third quarter of the set
The range of data set one is 5-2=3 and of set two is 12-1=11
The interquartile range of set one is 5 - 2 = 3
The interquartile range of set two is 5 - 1.5 = 3.5
Thus, the box plot is not symmetrical for either data set.
