I'll just do a relative frequency for the whole table:
Enjoyed Did not Enjoy Total
Males 47 13 60
Females 53 3 56
Total 100 16 116
Enjoyed Did not Enjoy Total
Males 47/116 = 0.41 13/116 = 0.11 60/116 = 0.52
Females 53/116 = 0.45 3/116 = 0.03 56/116 = 0.48
Total 100/116 =0.86 16/116 = 0.14 116/116 = 1.00
<span>
I'm not sure where a and b should be but based on the table: it can a = 41% ; b = 3% or a = 47% or b = 3%</span>
Answer:
The answer is the first one - Additive Inverse.
Photomath i use it for my math all the time it gives you the option for how you wanna solve it and shows you how to solve it
a. The difference between two outputs that are 1 unit apart.
You need to Use y2 - y1 / x2 - x1 to find the difference
I will choose x2 as 1 and x1 as 0
(29 - 21) / (1 - 0)
8/1 so The difference is 8 per 1 unit.
b. Use the same formula
I will choose -3 as x2 and -5 as x1
(5 - (-11)) / (-3 - (-5))
(5 + 11) / (-3 + 5)
16 / 2 so the difference is 16 per 2 units.
c. I will choose 2 as x2 and -1 as x1
(45 - 21) / (2 - (-1))
24/3 so the difference is 24 per 3 units.
d. The ratios of the differences to the input intervals reduced all equal each-other, which is 8 per 1 unit.
