Answer:
t=2
Step-by-step explanation:
log4(7t+2)=2
Raise each side to the base of 4
4^log4(7t+2)=4^2
The log goes away
7t+2 = 16
Subtract 2 from each side
7t+2-2 = 16-2
7t = 14
Divide each side by 7
7t/7 = 14/7
t = 2
Answer:
The approximate 90% confidence interval is;
70,244 to 70,732
Step-by-step explanation:
Here, we want to calculate the approximate 90% C.I for the situation
Mathematically;
CI = mean ± (z * SD)/√n
From the question;
mean = 70,438
SD = 645.3
n = 30
we can get z from the CI table
90% CI is same as; 1.645 z-score
So , substituting these values;
CI = 70,438 ± ( 1.645 * 645.3)/√30
CI = 70,438 ± 194
So the CI = 70,438 -194 to 70,438 + 194
= 70,244 to 70,732
Answer:
It is a solution of the ordered pair.
Step-by-step explanation:
The y intercept is (0,-2)
Answer:
see explanation
Step-by-step explanation:
A linear function is a straight line so all you have to do is find a slope and a y-intercept
