Answer:
2x-2+3x
Step-by-step explanation:
2x-2+3x
combine like terms (2x + 3x = 5x)

Answer:
15$
Step-by-step explanation:
15$
X=4
because -3x= -11-1
-3x= -12
x= -12/-3
Answer:
The best point estimate for a 95% confidence interval for the proportion of veterinary clinics that do not treat large animals is 0.733±0.079 i.e between
0,654 and 0.812.
Step-by-step explanation:
Confidence Interval can be calculated using p±ME where
- p is the proportion that do not treat large animals ( =0.733)
- ME is the margin of error from the mean
and margin of error (ME) around the mean can be found using the formula
ME= where
- z is the corresponding statistic in 95% confidence level (1.96)
- p is the sample proportion ()
- N is the sample size (120)
Then ME= ≈ 0.079
Then 95% confidence interval is 0.733±0.079
