find the unit rate and show work
289 miles on 10 gallons
Answer:
28.9 miles per gallon
Step-by-step explanation:
unit rate is usually something per something. Like miles per hour. In this case we have mile per gallon. MPG.
Unit rate is basically A number X per 1 of something.
so in this cares X per gallon.
we want 10 gallons to go to 1 gallon. So we divide by 10 to get to 1. But if we divide by 10 on one side, we have to do it to the other side. so 289/10=28.9
so our final answer is:
28.9 miles per gallon

A water treatment plant needs to maintain the ph of the water in the
reservoir at a certain level. To monitor this, they take 2 oz. of water at 37
locations every hour, measure the ph at each of those locations, and find
their average. If the ph level of the reservoir is ok, the results at each
location will have varying results, with an average pH of 8.5 and a standard
deviation of 0.22. If the pH level of the reservoir is ok, what is the probability
that the sample average is LESS than 8.40?
0.9971
O 0.3264
• 0.0029
• 0.6736
Using the normal distribution and the central limit theorem, it is found that there is a 0.0029 = 0.29% probability that the sample average is LESS than 8.40.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].In this problem:
The mean is of [tex]\mu = 8.5[/tex].The standard deviation is of [tex]\sigma = 0.22[/tex].A sample of 37 is taken, hence [tex]n = 37, s = \frac{0.22}{\sqrt{37}} = 0.0362[/tex].The probability that the sample average is LESS than 8.40 is the p-value of Z when X = 8.4, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
By the Central Limit Theorem
[tex]Z = \frac{X - \mu}{s}[/tex]
[tex]Z = \frac{8.4 - 8.5}{0.0362}[/tex]
[tex]Z = -2.76[/tex]
[tex]Z = -2.76[/tex] has a p-value of 0.0029.
0.0029 = 0.29% probability that the sample average is LESS than 8.40.

A hard-boiled egg is removed from a pot of hot water and set on the table to cool. The rate of change of the egg’s temperature T with respect to time t is proportional to the difference between the egg’s temperature in degrees Fahrenheit ( °F) and the room temperature of 75°F. Which of the following is a differential equation that describes this relationship, where k is a constant?
Answer:
dT/dt = k(T-75)
Step-by-step explanation:
dT/dt = the rate of change of the egg's temperature T with respect to time t
k = constant
(T-75) = difference between the egg's temperature and the room temperature 75 degree
The relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).
From the Newton's law of cooling, the rate of cooling of any object depends on the temperature difference between the object and the surroundings. This is usually expressed in a differential equation.
In this particular instant, the differential equation that shows the relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).

Explain how to find the surface area of rectangular prisms and cubes. What formulas can you use?
Answer:
surface area of rectangular prisms A=2(wl+hl+hw)
surface area of cubes A=[tex]6a^{2}[/tex]
Step-by-step explanation:
Answer:
The total surface area of a rectangular prism or cube is equal to the sum of the areas of each side.
The area of each side is equal to its length multiplied by its width or A = L x W.
Since the areas of opposite sides are equal, multiple each side area by 2 to obtain the areas of opposite sides.
where:
L = length
W = width
H = height
total area = (2)(L)(W) + (2)(L)(H) + (2)(W)(H)
or simplified:
total area = 2[(L)(W) + (L)(H) + (W)(H)]
