Assume that blood pressure readings are normally distributed with a mean of 125 and a standard deviation of 4.8.
If 36 people are randomly selected, find the probability that their mean blood pressure
will be less than 127.

The system of equations graphed below has how many solutions?

The swimming pool is open when the high temperature is higher than 20∘c. lainey tried to swim on monday and thursday (which was 33 days later). the pool was open on monday, but it was closed on thursday. the high temperature was 30 ∘c on monday, but decreased at a constant rate in the next 33 days. write an inequality to determine the rate of temperature decrease in degrees celsius per day, d, from monday to thursday.
