Answer:
d) The data are quantitative because they consist of counts or measurements.
Step-by-step explanation:
The number of cases of flu treated at a certain hospital in different years consists in integer numbers (there cannot be 108.4 cases of flu treated in one year, just 107, 108, 109, etc).
Therefore the date are quantitative because the data consists of numbers which are counts of a certain number of individuals who were affected by the flu during different years.
Answer:
In F: -3.5
Step-by-step explanation:
Answer:
<em>Their total sales (revenue) when they break-even is $250,000</em>
Step-by-step explanation:
<u>Linear Modeling</u>
Some situations can be mathematically represented as linear functions. If we are in a situation where a linear model is suitable, then we need two independent data to build it up.
The linear function can be expressed in the slope-intercept format:
y = mx + b
Where m and b are constant values.
The total cost function for Rally Co.'s to produce x toy trucks is:
C(x) = 200,000 + 4x
Given they sell each truck for $20, the revenue function is:
R(x)= 20x
The break-even condition is when the costs and the revenue are equal:
20x = 200,000 + 4x
Subtracting 4x:
16x = 200,000
Dividing by 16:
x = 200,000/16
x = 12,500 toy trucks
The revenue at this production level is:
R(x)= 20*12,500=250,000
Their total sales (revenue) when they break-even is $250,000
A. Strict gun control laws, more money allocated for welfare programs, and more lenient immigration laws.
Answer:
Step-by-step explanation:
x^2+8x-3=0 (move constant to other side by adding 3 to each side)
x^2+8x=3 (halve thr linear coefficient, square it and add to each side, (8/2)^2=16)
x^2+8x+16=3+16 (now the left side is a perfect square)
(x+4)^2=19 (now take the square root of each side)
x+4=+-(19^(1/2)) (finally subtract the constant to isolate x by itself)
x= -4+-(19^(1/2))
x=negative four plus or minus the square root of nineteen
