Step-by-step explanation:
The little number above the number is the exponent so technically, the number is already simplified in Kindergarden terms but the correct way is to multiply the exponent by the number
Answer:
Step-by-step explanation:
To find the equation of the tangent to the given function, you must differentiate the function with respect to 'x'. The derivative (y prime) will give the tangent line at any point along the function. After we find the tangent equation, we let x equal zero which will alow us to find the slope at that point.
Begin by bringing the entire denominator to the top. If not, you'll have to do the quotient rule which is very annoying 99% of the time. You will get:
With this now, you can use the chain rule twice. Begin by differentiating:
Use the chain rule:
Use the chain rule again:
Simplify:
Let x = 0 to get:
This is an exponential equation with a starting value of 12000 and an increase of 15% each years.
The following are true:
C. Each year, it increases by 15%
E. The painting's value was 12,000 at the time is was sold.
Answer:
0.8554 is the probability that the proportion of students living in dormitories is between 0.70 and 0.85
Step-by-step explanation:
We are given the following in the question:
Proportion of students who live in dormitories = 80%
Sample size, n = 80
Thus, the number of students follow a binomial distribution,
We use normal approximation to the binomial distribution to find the probability.
Parameters of Normal distribution:
We have to find the probability that the sample proportion (the proportion living in the dormitories) is between 0.70 and 0.85.
Thus, 0.8554 is the probability that the proportion of students living in dormitories is between 0.70 and 0.85
