Add -6 to both sides
square root x+6-6=7+-6
square root x=1
Solve square root
x= 1^2 ( square root both sides )
x=1
I hope that's help !
Answer:
C. I took the quiz
Step-by-step explanation:
a. The probability of taking out a purple flower is 0.47.
b. The probability that out of a sample of 5 flowers at least 3 flowers are yellow 0.56.
c. The standard deviation of the distribution for proportion of yellow flowers is 0.22.
d. The probability that out of the 263 samples, at most 150 of them are yellow is 0.90.
Check the explanation
Y = 11.5 + 4.5*X1 -2.5*X2 +0.7*X3+1.6*X4 -2.4*X5 -2.8*X6
FOR JANE
X1 =1 , X2 =1 , X3 =5 , X4 =0 ,X5=0, X6=1
SO,
Y =11.5+(4.5*1)-(2.5*1)+(0.7*5)+0+0-(2.8*1)
= 14.2
..........................
FOR Sophie
X1 =1 , X2 =1 , X3 =10 , X4 =1 ,X5=0, X6=0
so,
Y =11.5+(4.5*1)-(2.5*1)+(0.7*10)+ (1.6*1)+0+0
= 22.1
