Using the binomial distribution, it is found that there is a 0.6836 = 68.36% probability that she guesses at least one right.
For each question, there are only two possible outcomes, either she gets it right or she does not get it right. The probability of getting a question right is independent of any other question, hence the binomial distribution is used to solve this question.
What is the binomial distribution formula?The formula is:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The parameters are:
x is the number of successes.n is the number of trials.p is the probability of a success on a single trial.In this problem:
There are 5 questions, hence n = 5.For each question, she guesses one out of 4 options, hence p = 1/4 = 0.25.The probability that she guesses at least one right is:
[tex]P(X \geq 1) = 1 - P(X = 0)[/tex]
In which:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{4,0}.(0.25)^{0}.(0.75)^{4} = 0.3164[/tex]
Hence:
[tex]P(X \geq 1) = 1 - P(X = 0) = 1 - 0.3164 = 0.6836[/tex]
0.6836 = 68.36% probability that she guesses at least one right.

Carlton can hire only two full-time employees, but he needs even more help to make the two products he sells. Product alpha has a contribution margin per unit of limited resource of $750 and a unit contribution margin of $600. Product beta has a contribution margin per unit of limited resource of $975 and a unit contribution margin of $400. Carlton thinks he will be able to afford hiring an extra employee to work 150 hours per month, but he is unsure which product to have the employee work on. Which product would result in the highest additional contribution margin?.
The product that would result in the highest contribution margin is; Product Beta
What is contribution Margin?In this question, we see that production is limited by a particular resource named Labor work Hours.
Now, to determine the product to manufacture, Carlton has to rank the Contribution per unit of the limiting factor which is either labor of Product Alpha or Product Beta.
Contribution per limiting factor is gotten from:
Product Alpha; $750 per unit of limited resource
Product Beta; $975 per unit of limited resource
Finally, the Product with highest Contribution per limiting factor will be the one with the highest contribution margin and must be first to be worked upon.

A 190 g block is pressed against a spring of force constant 1. 60 kn/m until the block compresses the spring 10. 0 cm. The spring rests at the bottom of a ramp inclined at 60. 0° to the horizontal. Using energy considerations, determine how far up the incline (in m) the block moves from its initial position before it stops under the following conditions.
How far up the incline (in m) the block moves from its initial position before it stops is 4.96 m
Law of conservation of energy
From the law of conservation of energy, the total mechanical energy at the bottom of the incline, E equals the total mechanical energy when the mass stops, E'
So, E = E'
U + P + K = U' + P' + K' where
U = initial elastic potential energy = 1/2kx² where k = spring force constant = 1.60 kN/m = 1.60 × 10³ N/m and x = spring compression = 10 cm = 0.1 m, P = initial gravitational potential energy = 0 J, K = initial kinetic energy = 0, U' = final elastice potential energy = 0, P' = final gravitational potential energy = mgh where m = mass of block = 190 g = 0.190 kg, g = acceleration due to gravity = 9.8 m/s² and h = vertical height block moves and K' = final kinetic energy = 0 (both kinetic energies are zero since the body is at rest at both positions)Substituting the values of the variables into the equation, we have
U + P + K = U' + P' + K'
1/2kx² + 0 + 0 = 0 + mgh + 0
1/2kx² = mgh
Vertical height block moves
making h subject of the formula, we have
h = kx²/2mg
substituting the values of the variables into the equation, we have
h = kx²/2mg
h = 1.60 × 10³ N/m(0.1 m)²/(2 × 0.190 kg × 9.8 m/s²)
h = 1.60 × 10³ N/m × 0.01 m²/(3.724 kgm/s²)
h = 16.0 Nm/(3.724 kgm/s²)
h = 4.296 m
Distance up the incline the block moves
Now, the distance up the incline the block moves is L = h/sinФ where
h = vertical height block moves = 4.296 m and Ф = angle of incline = 60.0°Substituting the values of the variables into the equation, we have
L = h/sinФ
L = 4.296 m/sin60.0°
L = 4.296 m/0.8660
L = 4.96 m
So, how far up the incline (in m) the block moves from its initial position before it stops is 4.96 m
