Answer:
Yes it appropriate to use the normal approximation to find the probability that more than 43% of the people in the sample have high blood pressure
Step-by-step explanation:
From the question we are told that
The population proportion is p=0.4
The sample size is n = 39
The sample proportion is
Generally for normal approximation to be used
so np = 39 * 0.4 = 15.6 > 10
and
so n(1-p ) = 39(1-0.4) = 23.4 >10
Given that the both condition is meet it mean that it appropriate to use the normal approximation to find the probability that more than 43% of the people in the sample have high blood pressure

Answer:
-10x +30
Step-by-step explanation:
10(-⅘x + 3) -2x
Distribute
10 *-4/5x + 10*3 -2x
-8x+30 -2x
Combine like terms
-10x +30
