Answer:

110 students walk or bike to school.

Step-by-step explanation:

48% of the 208 students walk, whereas 5% bike.  Combining 48% and 5%, we get 53%.  

53% of the total number, n, comes to 208 students.

This number is 0.53(208 students), or 110 students.

110 students walk or bike to school.

Graph the exponential function.<br> f(x)= -(5/2)^x
7nadin3 [17]

Answer:

  see below

Step-by-step explanation:

Your spreadsheet or graphing calculator can do this for you.

__

If you want to do it by hand, pick a few values for x, compute the corresponding values of f(x), plot those points, and draw a smooth curve through them. You know the horizontal asymptote is y=0, and the whole graph is in the 3rd and 4th quadrants, since the exponential function has been reflected over the x-axis by the leading minus sign.

A random sample of 10 colleges was taken. A 95% confidence interval for the mean admission rate was left parenthesis 52.8 % comm
garik1379 [7]

Answer:

a. We are confident that the mean admission rate is between 52.8% and 75.0%

Step-by-step explanation:

When you have an unknown population parameter you can use a sample to delimit an interval in which this parameter is, the interval is called confidence interval and the confidence level is the probability of the parameter being inside the interval. The confidence interval is represented by a pair of numbers, in this case, the pair is (52.8%, 75.0%) and the confidence level is 95%, with that level you can say that you're confident that the mean admission rate is between  (52.8%, 75.0%).

PLEASE ANSWER picture shown
Alexxx [7]
\frac{x}{2} + \frac{7}{9x}
= \frac{x*9x}{2*9x} + \frac{7*2}{9x*2}
= \frac{9x^2}{18x} + \frac{14}{18x}
= \frac{9x^2+14}{18x}

Therefore the answer is B.
