Answer:
(4+x)>6
See "the sum of 4 and x" means '4+x' and "greater than 6" means the other number ,aka x which equals 4+x, is greater than six. So, the answer comes out to be (4+x)>6.
Answer:
No, because all the expected frequencies must be higher than 5.
Step-by-step explanation:
The chi-square test might be performed in those situations in which we need to know if a series of observations adjust or not to a theoretical function, such as the normal, Poisson, or binomial.
The chi-square test does not require the number of files to coincide with the number of columns in the table. It does not establish any restriction about the number of modalities per variable. However, the expected frequencies or counts should not be less than five.
In the exposed example, this unique rule is not accomplished, so the chi-square test can not be performed.

Answer:
-6x+104/5
Step-by-step explanation:
Distribute: (4)(x)+(4)(5)+-10x+4/5 = 4x+20+ -10x + 4/5 combine like terms: (4x+-10x) + (20+4/5) simplify: -6x 104/5 answer: -6x+104/5
