Answer: 650
Step-by-step explanation:
When prior estimate of population proportion is known , then the formula to find the required sample size is given by :-
, where p= population proportion
E= margin of error
z* = Critical value.
Let p be the proportion of adults able to identify a Toyota Scion by brand and model name.
As per given , we have
p = 12%= 0.12
E= 2.5%=0.025
Critical value for 95% confidence interval : z* = 1.960 [By z-table ]
Then, the required sample size = 
Thus , the required sample size = 650
Answer:
zeros: x = -3, 3
Step-by-step explanation:
The zeros are the x values where the graph intersects the x-axis. to find the roots, replace the y with 0 and solve for x.

Answer:
-6.3
Step-by-step explanation:
2.6 * 10 (10 hours and 2.6 degrees) = 26
19.7 - 26 = -6.3
Following rules of logs, we can do the following:
log x^4 - log y^(1/2) + log z^3
Combine the first and 3rd factors to get log [x^4*z^3]
Seeing that the neg. sign signifies division, write this new term - log y^(1/2) as a quotient:
[x^4*z^3]
log ----------------
y^(1/2)
