Create class savingsaccount. use static variable annualinter-estrate to store the annual interest rate for all account holders. each object of the class contains a private instance variable savingsbalance indicating the amount the saver currently has on deposit. provide method calculatemonthlyinterest to calculate the monthly interest by multiplying the savingsbalance by annualinterestrate divided by 12- this interest should be added to savingsbalance. provide a static method modifyinterestrate that sets the annualinterestrate to a new value. write a program to test class savingsaccount. instantiate two savingsaccount objects, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. set annualinterestrate to 3%, then calculate the monthly interest for each of 12 months and show the new balances for both savers. next, set the annualinterestrate to 8%, calculate the next month's interest and show the new balances for both savers.

in 2001, dell computer became the world’s largest personal computer vendor, continuing to

gain market share and post profits in an industry struggling with slumping sales and billions of

dollars in losses. dell sells 90% of its pcs directly to the final customer, largely bypassing the

reseller channel that accounts for most of the world’s pc sales. this direct customer relationship

is the key to dell’s business model, and provides distinct advantages over the indirect sales

model. dell’s direct relationship with the customer allows it to tailor its offerings to customer

needs, offer add-on products and services, and use the internet to offer a variety of customer

services. in addition, dell’s pcs are built to customers’ specifications upon receipt of an order,

giving dell additional advantages over indirect pc vendors who must try to forecast demand and

ship products based on those forecasts. dell’s direct sales and build-to-order model has achieved

superior performance in the pc industry in terms of inventory turnover, reduced overhead, cash

conversion, and return on investment (kraemer, et al., 2000).

explanation:

ans.

heterothermic organisms include those organisms that can switch between homeothermic (having body temperature higher than environment) and poikilothermic (having variation in internal body temperature) strategies.

some migratory birds show heterothermy as they decrease their metabolic rate during cold nights to keep their body temperature low. drop in metabolic rate allows increase in production efficiency of birds that reduces the internal body temperature to make it equal to external cold temperature during cold nights.

thus, the correct answer is 'birds allow their temperature drop in order to increase their production efficiency.'
