b = 8
Answer:
Hello there!^^
Step-by-step explanation:
✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰✰
Divide both sides by 3If there is two negtives it makes a positiveSimplify Add 2 to both sidesAnd simplify again~~~~~~~~~~~~~~~~~~~~~~
1. = -18/-3
2. 18/3
3. b - 2 = 6

Two integers are multiplied , and their product is a positive number . What must be true about the two integers ? Give an example
The outside temperature at midnight today in Polina's hometown was 18 degrees Fahrenheit. The temperature increases by 1.2 degrees Fahrenheit each hour over the next 15 hours. Polina's school does not send students outside for recess if the outside temperature is 32 degrees Fahrenheit or lower. Recess at her school always starts on the half hour or hour. Which statement is true about recess at Polina's school?
Answer:
only students who have recess at 12 p.m. or later may go out
Step-by-step explanation:
Let the time after midnight be represented by t, and the temperature be y. Since the temperature increases by 1.2 degrees Fahrenheit each hour, the time taken to reach 32 degrees Fahrenheit can be gotten from:
y = 1.2t + 18
put y = 32
32 = 1.2t + 18
1.2t = 14
t = 14/1.2 = 11.67 hours
Since the recess starts at half hour or hour, hence the recess would start at t = 12 hours, i.e. at 12 p.m.
Hence only students who have recess at 12 p.m. or later may go out
Answer:
i know im late but here only students who have recess at 12 p.m. or later may go out

Is this angle supplementary or congruent?
Answer
Step-by-step explanation:
the answer is supplementary because congruent are slant angles
find the value of X and y
Answer:
x=24cm
y=20,78cm
Step-by-step explanation:
sen(30)=[tex]\frac{12}{x}[/tex] -> x*sen(30)=12 -> x=[tex]\frac{12}{sen(30)}[/tex]= 24cm
cos(30)=y/x -> cos(30)= y/24 -> y=24*cos(30)= 20,78cm

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]

B. The slope of f(x) is 2 and the slope of g(x) is 5.
C. The slope of f(x) is -2 and the slope of g(x) is - 3.
D. The slope of f(x) is -3 and the slope of g(x) is -2.
EXPLAIN
Answer:
A.
Step-by-step explanation:
the slope of a line is behind the x in a linear equation.
f(x)=5x-2 is a linear equation
So, the slope of f(x) is 5.

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

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)
