So,, there are 5 different flavors. A total of 180 people were asked. Hence, the hypothesis that there is no significant difference is that every flavor gets 180/5=36 flavors. x^2=

. In this case, mi is the proportion of the hypothesis, thus 36, n=180 and xi is the number of actual observations. Substituting the known quantities, we get that x^2=9. The degree of association is given by

. This yields around 0.10, much higher than our limit.
Answer:
x=12
Step-by-step explanation:
7+x=2x-5
12=1x
x=12
Answer:
option b
Step-by-step explanation:




x = -3 (Not possible)
x = 5
So, x = 5
