Hotel A is a 4-star hotel and costs $125 per night and Hotel B is a 3-star hotel and costs $80 per night. You cannot spend more than $800 on hotels. Write a system of inequalities to model this situation. Then graph the system.

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed

Rationalize the denominator- 12x/√x-10
