either
-(3x+3)-2x (less than) -4(x-2)-2
-3x+3-2x (less than) -4x +8-2
-5x+3 (less than)-4x+6
Or if you need it simplified
-5x +3 (less than) -4x+6
+4x 4x
-x+3 (less than) 6
-3 -3
-x(less than) 3
(-x/-1) Less than (3/-1)
x (less than) -3
(didnt have the less than greater than sign so typed it)
Answer:
she can buy 6 dolls
Step-by-step explanation:
Answer:
The C.I. at 95% is 185±9.9583 or C.I.[175 to 195].
Step-by-step explanation:
Given:
Mean =185 mg
Standard deviation=17.6
Total number of samples=12
To Find:
95% of Confidence interval .
Solution:
We know that formula for C.I is given by ,
<em>C.I.=mean±Z[standard deviation/Sqrt(Total no of samples)]</em>
So using all above given values we get ,
Here Zscore at 95% is Z=1.96
So
C.I.=185±1.96[17.6/Sqrt(12)]
=185±1.96[17.6/3.464]
=185±1.965[5.0808]
=185±9.9583
In short C.I. is given as at 95% C.I.[175 to 195].
