2/3y = 1/4. y = ___?
3/8
5/12
11/12
2 2/3
Answer:
First option
Step-by-step explanation:
Given the following question:
[tex]\frac{2}{3} y=\frac{1}{4}[/tex]
To find the answer we need to isolate the variable, in order to do that we need to use inverse of operations on this problem.
[tex]\frac{2}{3} y=\frac{1}{4}[/tex]
[tex]3\times\frac{2}{3} =2[/tex]
[tex]\frac{1\times3}{4} =\frac{3}{4}[/tex]
[tex]\frac{2y}{2} =y[/tex]
[tex]\frac{3}{4} \div2=\frac{3}{8}[/tex]
[tex]y=\frac{3}{8}[/tex]
Your answer is "y = 3/8" or the first option.
Hope this helps.

A bakery sells rolls in units of a dozen. The demand X (in 1000 units) for rolls has a gamma distribution with parameters α = 3, θ = 0.5, where θ is in units of days per 1000 units of rolls. It costs $ 2 to make a unit that sells for $ 5 on the first day when the rolls are fresh. Any leftover units are sold on the second day for $ 1. How many units should be made to maximize the expected value of the profit?
Answer:
The value is [tex]E(X) = \$ 1.7067 [/tex]
Step-by-step explanation:
From the question we are told that
The parameters are α = 3, θ = 0.5
The cost of making a unit on the first day is c = $2
The selling price of a unit on the first day is s = $5
The selling price of a leftover unit on the second day is v = $ 1
Generally the profit of a unit on the first day is
[tex]p_1 = 5 - 2[/tex]
[tex]p_1 = \$3 [/tex]
The profit of a unit on the second day is
[tex]p_2 = 1 - 2[/tex]
=> [tex]p_2 = - \$1 [/tex]
Generally the probability of making profit greater than $ 1 is mathematically represented as
[tex]P(X > 1 ) = Gamma (X ,\alpha , \theta)[/tex]
=> [tex]P(X > 1 ) = Gamma (1 ,3 , 0.5)[/tex]
Now from the gamma distribution table we have that
[tex]P(X > 1 ) = 0.67668[/tex]
Generally the probability of making profit less than or equal to $ 1 is mathematically represented as
[tex] P(X \le 1 ) = 1 - P(X > 1 )[/tex]
=> [tex] P(X \le 1 ) = 1 - 0.67668[/tex]
=> [tex] P(X \le 1 ) = 0.32332[/tex]
So the probability of making $3 is [tex]P(X > 1 ) = 0.67668[/tex]
and the probability of making -$1 is [tex] P(X \le 1 ) = 0.32332[/tex]
Generally the value of profit per day is mathematically represented as
[tex]E(X) = 3 * P(X > 1 ) + (-1 * P(X \le 1 ) )[/tex]
=> [tex]E(X) = 3 * 0.67668 + (-1 * 0.32332 )[/tex]
=> [tex]E(X) = \$ 1.7067 [/tex]

Write the equation of the line, in slope-intercept form, with the
following information:
-1
slope:
3
y-intercept: (0, -3)
Answer:
y=3x-3
Step-by-step explanation:
since the line must pass through (0,-3), you must have the second number (or y intercept) in the equation be -3. since the slope must be 3 then it will be shown as 3x. put it all together to get y=3x-3. not sure what the -1 is doing there but y=3x-3 passes through (0,-3)

A business breaks even when the production costs are equal to the revenue. The expression 120 + 4x represents the cost of producing z items. The selling price is $5 for each item. Write an expression for the revenue generated by selling x items. How many items would you need to sell to break even? Write an equation and solve it. Enter the coIrect answers in the boxes. Hint Expression for revenue: Equation: Items needed to sell to break
Step-by-step explanation:
We know that revenue= production=break even point
given that the expression for cost of production is
z=120+4x---------------1 cost of production
where x is the number of items produced
also the selling price per item is $5
The revenue generated from the production of x items is(let the revenue be y)
y=5x------------2 revenue equation
break-even is when y=z
120+4x=5x
solving for x we have
120=5x-4x
120=x
x=120items

The orbital period, p, of a planet and the planet’s distance from the sun, a, in astronomical units is related by the formula p = a superscript three-halves. if saturn’s orbital period is 29.5 years, what is its distance from the sun? 9.5 au 19.7 au 44.3 au 160.2 au
The distance of Saturn from the sun is 9.5 astronomical units.
Orbital period p of a planet and the planet’s distance from the sun, a in astronomical units are related by:
[tex]p = a^{3/2}[/tex]
What is the orbital period?The orbital period is the time a given astronomical object takes to complete one orbit around the sun.
Given that Saturn's orbital period is 29.5 years.
So, [tex]29.5 = a^{3/2}[/tex]
[tex]a = 29.5^{2/3}[/tex]
a = 9.5 au

jasmine has all nickels x and dimes y in her coin jar. if she has 36 coins in all, and four more dimes than. nickels find how much money she has in her coin jar
Answer:
She has 18 nickels and 36-18= 18 dimesSolving steps:
Question: jasmine has all nickels x and dimes y in her coin jar. if she has 36 coins in all, and four more dimes than. nickels find how much money she has in her coin jar
Find: how much money she has in her coin jar
Solution: let's make an equation for this problem
She has 4 more dimes than nikels:y= x+4 Let's use this value for y in the next equation:
x+x+4= 362x= 36x= 18
she has 18 nickels and 36-18= 18 dimes
The required Jasmine has 16 nickles and 20 dimes which constitute $2.80 in her coin jar.
Let's use the given information to set up a system of equations to solve for the number of nickels (x) and dimes (y) in Jasmine's coin jar.
We are given that Jasmine has a total of 36 coins in her jar, so we have the equation:
x + y = 36 -- Equation 1
We are also given that Jasmine has four more dimes than nickels, which can be expressed as:
y = x + 4 -- Equation 2
Now, let's solve this system of equations. We can substitute Equation 2 into Equation 1 to eliminate y:
x + (x + 4) = 36
2x = 36 - 4
x = 16
Now that we have the value of x, we can substitute it back into Equation 2 to find y:
y = x + 4
y = 16 + 4
y = 20
Therefore, Jasmine has 16 nickels (x) and 20 dimes (y) in her coin jar.
To find the total amount of money she has, we need to calculate the value of the nickels and dimes separately:
Value of nickels = 0.05 * 16 = $0.80
Value of dimes = 0.10 * 20 = $2.00
The total amount of money in her coin jar is:
$0.80 + $2.00 = $2.80
Jasmine has $2.80 in her coin jar.
