what dang boy u are you doing today and how to do it
Answer:
The average rate will be: 0.7 inches/hour
Hence, Option (4) is correct.
Step-by-step explanation:
As the average rate = change in y-values/change in x values
= Δy/Δx
From the table, it is clear that over the time interval 't=2' to 't=7', the values
snow depth 'd' inches change from d=1.5 to d=5.
Therefore,
Average rate = Δy/Δx
= (5-1.5) / (7-2)
= 3.5/5
= 0.7 inches/hour
Therefore, the average rate will be: 0.7 inches/hour
Hence, Option (4) is correct.
Answer:
12 = 5k/2
24 = 5k
Step-by-step explanation:
Raul is making chocolate chip pancakes.
The number of chocolate chips he uses is proportional to how many ounces of mix he makes.
Hence,
Chocolate chips ∝ Number of Ounces
Chocolate chips = c
Number of Ounces = m
= cm
c = km
Where k = Constant of Proportionality
The recipe said that for every 2 1/2 ounces of the mix, 12 chocolate chips be added.
Hence
12 = 21/2 × k
12 = 5/2 × k
12 = 5k/2
Cross multiply
12 × 2 = 5k
24 = 5k
The equation that represents the relationship between c the number of chocolate chips and m the number of ounces is
12 = 5k/2
24 = 5k
B because it’s a random sample and it’s not biased
Answer:
the roots are n = 1 + √15 and n = 1 - √15
Step-by-step explanation:
In this case I would immediately rewrite n² - 2n - 5 = 10 as
n² - 2n = 10 + 5 = 15.
To complete the square: Identify the coefficient of n (it is -2). Halve that, obtaining -1, square this result, and then add the outcome (1) to and subtract the outcome (1) to n² - 2n:
n² - 2n <em>+ 1 - 1 </em> = 15
Next, rewrite n² - 2n + 1 as the square of a binomial:
(n - 1)² = 15
Finally, take the square root of both sides:
n - 1 = ±√15
so that the roots are n = 1 + √15 and n = 1 - √15
