7/12*6/14
7*6=42
12*14=168
=42/168
=0.25 =1/4
56/72 can be simplified to 14/18, then to 7/9 *dividing by 4, then by 2*
28/32 can be simplified to 7/8 *dividing by 4*
70/90 can be simplified to 7/9 *dividing by 10*
7/9 and 7/9 are equivalent, so 56/72 and 70/90 are equivalent.
Answer:
C.
Step-by-step explanation:
i believe it is C but do not trust me on this :p
Group1 Group2 Total
Category 1 30 90 120
Category 2 14 32 46
Total 44 122 166
Relative frequency:
Group 1 Group 2 Row Total
Category 1: 30/166 = 0.18 90/166 = 0.54 120/166 = 0.72
Category 2: 14/166 = 0.08 32/166 = 0.20 46/166 = 0.28
Column Total: 44/166 = 0.26 122/166 = 0.74 166/166 = 1.00
The relative frequency is the derived by dividing the amount per cell by the total balance, which is 166. It denotes the parts of the rows and columns against the whole table.
Step-by-step explanation:
100 = ( 8 + 2x) ( 10 + 2x )
100 = 80 + 36x + 4x ^2 ( binomial product )
80 + 36x + 4x^2 = 100
80 + 36x + 4×^2 - 100 = 100 - 100
4x^2 + 36x - 20 = 0
I am not able to write the next steps but you can use symbolab to find out the answer and for the clear understanding
I am reay sorry
use symbolab app
