Plug in 300 for C(x), to get:
300=
Then subtract to get: 0=
Then use the quadratic formula and plug everything in. Use a calculator to simplify.
You'll get two answers: 29.486 and -0.513.
Since you can't sell <em>"negative" </em>tacos, use the positive solution
Around 29-30 tacos.
Answer:
x=440 gaL 90 % Antifreeze II
Step-by-step explanation:
In the problem, there are two types of antifreeze
antifreeeze I and
antifreeze II
antifreeze I 25 ----80 gal
Antifreeze II 90 ----- x gal
Total 80 ---------------- (80 + x ) gal
(25*80)+(90*x)=80(80+x)
2000+90x=6400+80x
90x-80x=6400-2000
10x=4400
divide both sides by 10 we have
x= 440
x=440 gaL 90 % Antifreeze II

Step-by-step explanation:
the equation of a line in slope-intercept form is
y = mx + c ( m is the slope and c the y-intercept )
(1)
y = 3x + 4 is in this form
with slope m = 3 and y-intercept c = 4
(2)
y = - x - is in this form
with slope m = - and y-in tercept c = -
(3)
rearrange 3x + y = - 4 into slope-intercept form
subtract 3x from both sides
y = - 3x - 4 ← in slope-intercept form
with slope m = - 3 and y-intercept c = - 4

Step-by-step explanation:
Theoretical probability is the actual chance of something happening based on raw numbers.
For example: The theoretical probability of tails on a coin flip is 1/2 or 50%. If you flipped a coin, you would expect 50% to be heads, 50% to be tails.
However, since this almost never happens, experimental probability is used to describe the actual results.
For example: If you flip the coin 50 times and 23 are tails, 27 are heads, then the experimental probability is 46% for tails and 54% for heads.
