Answer: There are 8 students at Hamilton Middle School with red hair.
Step-by-step explanation:
Given: The proportion of the students at Hamilton Middle School have red hair = 2% = 0.02
Total students in Hamilton Middle School = 400
Then , the number of students have red hair = (proportion of the students have red hair ) x (Total students )
= (0.02) x (400)
= 8
Hence, there are 8 students at Hamilton Middle School with red hair.
5+6.50+7.21=18.71 30-18.71=$11.29 left
The correct answer will be option C. Mode.
Mode is the most frequently occurring value of the data. From the above line plot we can see that the most frequently occurring value is 3. Even if 10 is removed from the line plot, 3 will still be the most frequently occurring value and will be the mode of the data. Thus removing 10 does not changes the mode of the data at all.
The mean will obviously be changed. The range is difference of maximum and minimum value. 10 was initially the maximum value. If 10 is removed, the maximum value will change and so does the Range of the data. Removing 10 changes the total number of data values, so the position of median also changes which changes the value of Median.
Therefore, the correct answer to this question is option C
Answer:
(1,3)
y= 3
x= 1
Step-by-step explanation:
7x+y=10
3x-2y= -3
solve the equation
y=10-7x
3x-2y= -3
substitute the value of y into an equation
3x-2(10-7x)= -3
distribute
3x-20-14x= -3
add 14x from both sides
17x-20= -3
add 20 from both sides
17x=17
divide both sides by 17
x=1
substitute the value of x into an equation
y=10-7•1
multiply 7 to 1
y=10-7
subtract
y=3
