Answer:

Hello There!!

Step-by-step explanation:

Firstly, find out how many students there are in 7 batches. You can do this by timesing 48 by 7 to get 336. So there are 336 students in 7 batches. Each student does 24 hours of community service in a year so do 336 times by 24 which is 8,064. Therefore,the college contributes 8,064 hours of community service in a year.

hope this helps,have a great day!!

A stock with a beta greater than 1.0 has returns that are​ ________ volatile than the​ market, and a stock with a beta of less t
djverab [1.8K]

Answer:

more, less

Step-by-step explanation:

Beta is a measure of volatility. It is used in calculating the cost of equity using the CAPM (Capital Asset Pricing Model formula).

A beta greater than 1 signifies that the returns from an investment is expected to be higher than the returns from the general market as the risk inherent in that investment is higher.

Similar to the economic concepts of elasticity, a change in one variable (in this case, beta of the stock) setting about a greater than proportionate change in another variable (returns from the stock).

Thus, a stock with beta of less than 1, will be less volatile than the market.

I hope this helps you understand the concept better.

I really need help with this section
Tpy6a [65]

Looks like you did most of it.

The next step would be setting them equal to 105, like the problem suggests.

5z+3x+7x=105

15x=105

x=7

Then we can plug back in to find the numbers.

5*7=35

3*7=21

7*7=49

35+21+49=105

The three numbers are 35, 21, 49.

Hope this helps.

頑張って!
