The average cost per household of owning a brand new car is Php 5,000. Suppose that we randomly selected 40 households, determine the probability that the sample mean for these 40 households is more than Php 5,350. Assume that the variable is normally distributed and the standard deviation is Php 1,230.

The velocity of a particle which moves along
the s-axis is given by
V=2 - 4t + 58312
, Where t is in seconds and v is
in meters per second. Evaluate the position s,
velocity v, and acceleration a when t = 3 s. The
particle is at the position S, = 3 m when t=0.

Evaluate ∫c 𝐹. 𝑑𝑟,where 𝐹 = 𝑋^2 − 𝑌^2𝑖 + 𝑥𝑦𝑗 and curve 𝐶 is the arc of the curve 𝑦 = 𝑋^3 from (0,0) to (2,8).
A program stores test scores in two int variables named myScore and expectedScore. Write the C++ code to compare the two scores and then display one of the following messages: “I met my expectations”, “I scored higher than expected”, or “I scored lower than expected”.
Make use of either a While Loop, For Loop or a Do While Loop to allow the program to repeat until a sentinel value or counter is used to break out of the loop
