X = 10
y = -2
x/y = 10/-2
x/y = -5
Hence, x/y = z
According to the laws of logarithm:
if log ₐ c =b
then:
aᵇ=c
hence, to solve the question we let:
log₆1296=a
thus to solve the above we re-write as follows:
6ᵃ=1296
the answer is option D
Answer:
After 25 years both the accounts will have the same balance.
Step-by-step explanation:
Let t years, both the account will have the same balance.
As account A has a beginning balance of $500 and grows by $25 per year.
So, the total balance of account A after t years = 500+25t
Similarly, account B has a beginning balance of $750 and grows by $15 per year.
So, the total balance of account A after t years = 750+15t
As both the accounts has the same balance, so
500+25t= 750+15t
25t-15t=750-500
10t=250
t=250/10
t=25 years
Hence, after 25 years both the accounts will have the same balance.
Answer:
C) The confidence interval is not biased.
Step-by-step explanation:
When a relationship between two variables is observed the confidence interval should not be biased. If the confidence interval is found to be biased then the observed results will be reliable and accurate. Regression analysis of heart rate and maximal oxygen uptake is analyzed and the correlation will not be equal to zero. This means there will be some correlation between the two variables.
