Loga x=n ⇔a^n=x
Therefore:
log₄ (x+20)=3
3⁴=x+20
64=x+20
x=64-20
x=44
Answer: x=44
we have given that 
.
we need to find 
.
we know that we need to plug t in place of x in the equation f(x)=2^x.
.for example for 
they have plugged 4 in place of x. so we plug in plug t in place of x .
one column should be added first
Answer: 2,100$
Step-by-step explanation:
Answer: We can be 95% confident that the true proportion of all college students gain weight in their freshman year.
Step-by-step explanation:
- A 95% confidence interval interprets that a person can be 95% confident that the true population parameter lies in it.
Given : A popular claim, nicknamed "freshman fifteen," states that many college students gain weight in their freshman year.
The 95% confidence interval as 55.9% < p < 78.4%.
Here : Population parameter = p , where p is the proportion of college students gain weight in their freshman year.
Interpretation of 95% confidence interval : We can be 95% confident that the true proportion of all college students gain weight in their freshman year.
