Answer:
Class 3rd has the highest relative frequency and class 4th has the lowest relative frequency.
Step-by-step explanation:
To calculate class width we use the formula given below;
Class Width = <u>Maximum Value - Minimum Value </u>
Number of Classes
Class Width : 
= 2 approximately.
Relative frequency is obtained by counting each class frequency.
Class Frequency Relative Frequency
1 - 2 7 0.1944
3 - 4 8 0.2223
5 - 6 10 0.2778
7 - 8 4 0.1111
9 - 10 7 0.1944
Class 3rd has the highest relative frequency and class 4th has the lowest relative frequency.
Answer:
A. 3/4
Step-by-step explanation:
Answer:
x= -2-√11. or. x= -2 + √11
Step-by-step explanation:
solving quadratic equation by completing the square
x^2+4x-7=0
x^2+4x=7
x^2+4x + (4/2)^2=7 + (4/2)^2 ( adding (1/2 coefficient of x)^2 on both sides
x^2+4x + 4=7 + 4
x^2+4x + 4=11. factorize(x^2+4x + 4) into (x + 2)^2
(x + 2)^2=11
√(x + 2)^2= + - √11
x + 2 = + - √11
there are two different solution .
x + 2 = -√11. or x + 2 = + √11.
x= -2-√11. or. x= -2 + √11.
Answer:
2
Step-by-step explanation:
You can ask yourself different ways to solve these kinds of problems.
I start with “Can the lowest number go evenly into the largest?”
The answer for this is no. So you work down the vine.
What do these numbers have in common? They are even!
What can all even numbers be divided by?
2!
Parallel lines have the exact same slope ( or else they would eventually run into each other). So the answer is -1/2 is the slope.
