Answer:
1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Step-by-step explanation:
The inicial concentration is 60,000, and this concentration triples every 4 days, so we can write the equation:
P = Po * r^t
where P is the final concentration after t periods of 4 days, Po is the inicial concentration and r is the ratio that the concentration increases (r = 3)
Then, we have that:
102000 = 60000 * 3^t
3^t = 102/60 = 1.7
log(3^t) = log(1.7)
t*log(3) = log(1.7)
t = log(1.7)/log(3) = 0.483
so the number of days that will take is 4*0.483 = 1.932 days (or approximatelly 1 day, 22 hours and 22 minutes)
Answer:
C
Step-by-step explanation:
A regression model is a function which can be used to predict behavior of the model. It takes data points in and forms a general pattern for the pattern using an equation. This model y = 12.3 + 0.12x is a linear regression model which means it has linear behavior (a line) where x is total yards gained and y is number of points scored. If one additional yard is gained then the score is likely to be 12.3 + 0.12(1) = 12.42. If two additional yards is gained then the score is likely to be 12.3 + 0.12(2) = 12.54. Notice the score increases by 0.12 points for every yard gained. This is answer choice C.
a.)The average points scored for teams who gain zero yards during a game is -12.3 points.
b.) The average yards gained will increase by .12 for every additional point scored.
c.) The average change in points scored for each increase of one yard will be 0.12.
d.) The average number of points scored per game is 12.3.

Answer:
b) 36
Step-by-step explanation:
area= ((sum of parallel lines) / 2) * hight
X = ((8 + (8+4+4))/2) *3
X= ((8+ (16) /2) *3
X= ((24)/2)*3
X= 12*3
x=36
Answer:
Zahara need to add 4 quarts of water to keep the consistency the same
Step-by-step explanation:
Let
x -----> the amount of dry ingredients in quarts
y -----> the mount of water in quarts
we know that
Batch 1
Isolate variable y
----> equation A
Batch 2
For x=10
substitute in the equation A and solve for y
The ratio batch 2 is 
therefore
Zahara need to add 4 quarts of water to keep the consistency the same
