8. In mathematics, you can create something called a piece-wise function. This is a graph that is made up of several functions at one time. Each function is only defined within a certain interval. You know this interval as a function's domain.
what is the probability that a random sample of 20 second grade students from the city results in a mean reading rate of more than 97 words per minute
Alisha used her bank card to buy a bus pass 3 times. Each time she bough a pass it cost her $13.75. She then deposited $30 into her bank account. Write an expression to find the change in Alisha's bank account in dollars as a result these transactions. Also, evaluate the expression to find the change in the account balance.
Can a normal approximation be used for a sampling distribution of sample means from a population with μ=52 and σ=9, when n=49?

8. In mathematics, you can create something called a piece-wise function. This is a graph that is made up of several functions at one time. Each function is only defined within a certain interval. You know this interval as a function's domain. For programming purposes, another way that you can write the interval (-3, 4] is-3 < x≤4. Using the piece-wise graph below, see if you can identify the three functions and their domains.
Felipe received a $25.00 gift card for a photo center. He used it to buy prints that cost 5 cents each. The remaining balance, B (in dollars), on the card after buying x prints is given by the following function. B(x)=25.00-0.05x What is the remaining balance on the card if Felipe bought 20 prints?
The volume V of a fixed amount of a gas varies directly as the temperature T and inversely as the pressure P. Suppose that V = 70 cm^3 when T = 420 kelvin and P = 18 kg/cm^2. Find the pressure when T = 140 kelvin and V = 60 cm^3.
b. For any triangles that are not right triangles, use any two of the sides 10 to make a right triangle. Explain.
