A ladder leen again a perfectly smooth vertical wall at angle of 30 to the horizontal.,
A load of 800N placed 3/4 of the way up, the ladder if the ladder rest at a rough horizontal surfaces which prellent shipping. Find the magnitude and direction of the reaction between the ladder and the ground.
The amount of sweetener used in a liter of milk tea is a normally distributed with a mean of 0.75 cup and a standard deviation of 0.6 cup.Β
a. Suppose 10 liters of milk tea are randomly selected, what is the probability that it will have at least a cup of sweetener?
b.Suppose 20 liters of milk tea are randomly selected, what is the probability that it will have less than half a cup of sweetener?
c.15 liters of milk tea is randomly selected, what is the probability that it will have 0.50 to 1.25 cups of sweetener?
Given that there are 3 apples, 1 pear and 2 oranges in a box and one would get 1 fruit in that box what are the possible value of a random variable A given that A are the number of apple.
We Filipinos are quite known for the habit of leaving at least one of the many pieces of food on the plate as it can't be equally divided among all at most times. Just like when 3 people decide to eat a pizza of 10 slices, there will often be at least one slice left on the box. To accurately show just how many pieces of things are left when divided by a certain number, we code it using modulo.

With aid of diagram describe how each of the following will affect the demand for personal computers: (a) a rise in incomes (assuming computers are a normal good); (b) a lower expected price for computers; (c) cheaper software; (d) computers become simpler to operate.
ο· Demand:ππ =ππβπ.ππβππ
ο· Supply:ππ =ππ.π+π.ππβππ
Imagine now that the government imposes a tax of $π. π on the producers of hammers.
a) What is the new equilibrium quantity?
write an expression that evaluates to true if and only if the string variable s equals the string "end".
The following data show the probability distribution of the number of speakers sold daily in an appliance shop during the past several months, X={0, 1, 2, 3, 4, 5} P(X)={.07, .18, .27, .19, .08, .21}, what is the probability that exactly no speakers will be sold?
2. Write a program in Java to take the postfix form of a mathematical expression. Evaluate the postfix expression and print the result. The postfix expression will contain single-digit operands and β+β, β-β, β*β, and β/β operators. You can use relevant Java built-in classes in your code. The sample inputs/ outputs are given below: Sample inputs and outputs: (Userβs inputs are shown in bold) The postfix expression: 543*+82/- The final result: 13
Explain why an expansionary fiscal policy is more appropriate when the economy is in recession. Support your discussion with examples.
