Shown here are four frequency distributions. Each is incorrectly constructed. State the reason why.
Answers
Answer/Step-by-step explanation:
a. The the class width for the 1st, 2nd, 3rd, and 5th row equal 5 in the frequency distribution. Whereas, in the 4th row, the class width is 4 (49 - 45). This makes the construction incorrect.
b. Here, the upper limit of each consecutive class was used as the lower limit if the next class. For example, 9 is a member of the first class, which is the upper limit if the class in the first row, it ought not to be included as a member of the next class in the second row.
c. In the 3rd row, the lower limit of the class should be 133, NOT 138.
d. Different class width were used.
Row 1 class width = 13 - 9 = 4
Row 2 class width = 19 - 14 = 5
Row 3 class width = 25 - 20 = 5
Row 4 class width = 28 - 26 = 2
Row 5 class width = 32 - 29 = 3
The reason for all the frequency distribution is given below and this can be determined by using the given data.
Check all the options in order to determine the reason for the incorrect construction.
A) The given frequency table is given below:
Class Frequency
27-32 1
33-38 0
39-44 6
45-49 4
50-55 2
In the fourth row, the class should be ending with 50.
B) The given frequency table is given below:
Class Frequency
5-9 1
9-13 2
13-17 5
17-20 6
20-24 3
In the fourth row, the class should be ending with 21.
C) The given frequency table is given below:
Class Frequency
123-127 3
128-132 7
138-142 2
143-147 19
In the second row, the class should be starting from 127.
D) The given frequency table is given below:
Class Frequency
9-13 1
14-19 6
20-25 2
26-28 5
29-32 9
In the second row, the class should be starting from 13.

If the sum of two consecutive number is 71 and one number is x then the other number is options are x +(x+1)=71,x+(x+2)=71,x+x=71,none of these
Answers
Answer:
x + (x + 1) = 71
Step-by-step explanation:
One number is x
So, other number = x + 1
Since, the sum of two consecutive number is 71
Therefore, x + (x + 1) = 71
Answer:
x + (x + 1) = 71Step-by-step explanation:
x - some integer
then the consecutive integer would be:
x+1 or x-1 (as x is consecutive to x-1)
the sum: x + (x + 1) or (x - 1) + x
the sum is 71 so:
x + (x + 1) = 71 or (x - 1) + x = 71

Is √10 repeating, greater than, less then, or equal to five? Because 10 lies between two consecutive perfect squares (in increasing order) ______ and ______, √10 repeating is located between the square roots of these two numbers. This means √10 repeating is located between ______ and ______, so √10 repeating is less than 5.
Answers
Given:
The number is [tex]\sqrt{10}[/tex].
To find:
The correct values for each blank.
Solution:
The given number is [tex]\sqrt{10}[/tex].
We know that, 10 lies between two consecutive perfect squares 9 and 16, [tex]\sqrt{10}[/tex]. repeating is located between the square roots of these two numbers.
[tex]\sqrt{9}=3\text{ and }\sqrt{16}=4[/tex]
This means [tex]\sqrt{10}[/tex] repeating is located between 3 and 4.
So, [tex]\sqrt{10}[/tex] repeating is less than 5.
Therefore, Blank-1=9, Blank-2=16, Blank-3=3 and Blank-4=4.

if 5x+3y=41 and x+y=11, then the value y-x is
Answers
Answer:
[tex]y-x=3[/tex]
Step-by-step explanation:
Subtract y from both sides of the equation.
[tex]x = 11-y[/tex]
[tex]5x+3y=41[/tex]
Replace all occurrences of x in [tex]5x+3y=41[/tex] with 11 -y
[tex]x=11-y[/tex]
[tex]5(11-y)+3y=41[/tex]
simplify [tex]5(11-y)+3y=41[/tex]
[tex]x=11-y[/tex]
[tex]55-5y+3y=41[/tex]
add -5y and 3y
[tex]x= 11-y[/tex]
[tex]55- 2y=41[/tex]
Solve for y in the second equation.
Move all terms not containing y to the right side of the equation.
[tex]x=11-y[/tex]
[tex]-2y=-14[/tex]
Divide each term by − 2 and simplify.
[tex]x=11-y[/tex]
[tex]y=7[/tex]
Replace all occurrences of y in x
[tex]x=11-(7)[/tex]
[tex]y=7[/tex]
simplify.
[tex]x=4[/tex]
[tex]y=7[/tex]
Replace the variable x with 4 in the expression.
[tex]y-(4)[/tex]
Replace the variable y with 7 in the expression.
[tex](7) - (4)[/tex]
Multiply − 1 by 4 .
[tex]7-4[/tex]
Subtract 4 from 7 .

Answer:y-x=3
Step-by-step explanation: substitution method
5x+3y=41........ equation 1
x+y=11 .........equation 2
Since we are given two different equations in terms of two different linear equations, let us try to solve them using the concept of method of substitution:
we find that y=11-x
we will substitue y into equation 1
5x+3(11-x) = 41
5x+33-3x=41
5x-3x=41-33
2x=8
2x/2=8/2
x=4
x+y=11
then you substitute
4+y=11
y=11-4
y=7

SW=2x+y, WC= x-2y, W is the midpoint of SC, and SC=20, find the values of x and y.
Answers
Answer:
[tex]x= 6[/tex]
[tex]y = -2[/tex]
Step-by-step explanation:
Given
[tex]SW = 2x + y[/tex]
[tex]WC = x - 2y[/tex]
[tex]SC = 20[/tex]
Required
Determine x and y
Since W is the midpoint;
[tex]SW = WC = \frac{1}{2} * SC[/tex]
[tex]SW = WC = \frac{1}{2} * 20[/tex]
[tex]SW = WC = 10[/tex]
Substitute 10 for SW and WC
[tex]2x + y = 10[/tex] --- (1)
[tex]x - 2y = 10[/tex] ---- (2)
Make x the subject in (2)
[tex]x = 10 + 2y[/tex]
Substitute [tex]x = 10 + 2y[/tex] in (1)
[tex]2(10 + 2y) + y = 10[/tex]
[tex]20 + 4y + y = 10[/tex]
[tex]20 + 5y = 10[/tex]
Solve for 5y
[tex]5y = 10 - 20[/tex]
[tex]5y = -10[/tex]
Solve for y
[tex]y = -10/5[/tex]
[tex]y = -2[/tex]
Recall that [tex]x = 10 + 2y[/tex]
[tex]x = 10 + 2(-2)[/tex]
[tex]x = 10 -4[/tex]
[tex]x= 6[/tex]
