Answer is D
5(6-x)/2=60, x= -18
(6-(-18) x 5) / 2 =60
Answer:
The right solution is "-8.25".
Step-by-step explanation:
The given values are:
Sampled people,
n = 150
Null and alternative hypotheses will be:


The z-statistics will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
⇒ 
⇒ 
Upon slight rearrangement...
54xy+18y+45x+15 now factor 1st and 2nd pair of terms
18y(3x+1)+15(3x+1) which is equal to
(18y+15)(3x+1) and you can further factor the first binomial factor
3(6y+5)(3x+1)
The answer is 1561 yuans and 27 jiao.
