30. Shelby walks at a constant rate. The equation that represents this
relationship is d= 4t, where d is the distance in miles and t is the
time in hours.
a. What does the coefficient 4 tell you about Shelby?
b. Make use of structure. What question is answered by the
equation d=4(32)?
Answers
Answer:
Step-by-step explanation:
In order for 4*t to equal d, the 4 has to represent a rate with respect to time because the multiplication between them will cancel the time unit. We know this because of the formula d = rt with 'r' being rate
a: 4 is the rate at which Shelby walks, 4 miles per hour
b: T is replaced with 32, so the expression tells us the distance Shelby travels in 32 hours at a rate of 4 miles per hour

Answers
Answer:
D. 14.99d
Step-by-step explanation:
d represents the number of DVD's she purchased, and 14.99 was the cost for each DVD. Answer D is multiplying the variable d and the coefficient 14.99. When multiplying variables, there is no need to place a multiplication sign.
Answer:
C. 14.99 divided by d
Step-by-step explanation:
the answer is c because you don't know how many DVDs he bought so by dividing the answer you can then know the price of each DVD they bought.

A. There are 300 fish in a pond. 50 fish are tagged. If you catch one fish out of the pond, what is the probability that your fish is tagged? Write your answer in a fraction and a decimal. Explain and show your work.
B. Suppose you catch 100 fish out of this pond. How many of these fish would you expect to be tagged? Explain.
Answers
Answer:
B. 50
Step-by-step explanation:
Answer:
The probability is 16.6%
And if you catch 100 fish, you should expect at least 17 of them are tagged.
Step-by-step explanation:
Let A be the event of catching a tagged fish:
[tex]P(A) = \frac{50}{300} = \frac{1}{6} = 0.166[/tex]
Now if you catch 100 fish, each one has the probability of 1/6 and each event is independent of the other.
[tex]N = \frac{1}{6} * 100 = 16.6[/tex]

Read Bagheera’s words in this passage from The Jungle Book.
"O Akela, and ye, the Free People," he purred, "I have no right in your assembly; but the Law of the Jungle says that if there is a doubt which is not a killing matter in regard to a new cub, the life of that cub may be bought at a price. And the Law does not say who may or may not pay that price. Am I right?"
"Good! Good!" said the young wolves, who are always hungry. "Listen to Bagheera. The cub can be bought for a price. It is the Law." . . .
"To kill a naked cub is a shame. Besides, he may make better sport for you when he is grown. Baloo has spoken in his behalf. Now to Baloo's word I will add one bull, and a fat one, newly killed, not half a mile from here, if ye will accept the man's cub according to the Law. Is it difficult?"
