Answer:
20 miles
Step-by-step explanation:
Given the equation of the line of the graph, y = 8x, where,
y = distance the hurricane travelled in miles
x = time of travel in hours
8 = slope/speed in miles/hour
To find how far the hurricane travelled in 2.5 hours, substitute x = 2.5 into y = 8x
This:
y = 8(2.5)
y = 20 miles
Thus, from the graph, we can estimate this also. On the x-axis, between 2 and 3, we have 2.5 hours. The corresponding value of x = 2.5 is y = 20.
Answer: $28 unit rate
Step-by-step explanation:
420/15 = 28
Divide the second price by the second pounds. 9.95 / 5 = 1.99
So for every pound you get you pay 1.99 dollars. The second deal is better.
<span>What is the probability of landing on an even number, and then landing on a yellow?
</span>your answer should be this 2 of 5
If the first card (not replaced) is a 7, you're left with 51 cards, and the four aces are all there: you have probability 4/51 of picking an ace.
If the first card (not replaced) is an ace, you're left again with 51 cards, but these time only 3 aces are remaining in the pile: you have probability 3/51 of picking an ace.
Were the cards replaced, the information about the first card drawn would be completely meaningless, since the second pick would be a pick from a standard deck, and we'd have probability 4/52=1/13 of picking an ace.
In other words, if cards are replaced, it is like every pick is the first one, because whatever happened with the first pick has no consequences on the second.
On the other hand, if we do not replace cards, the outcome of the first pick is important, because we know that the card we picked will not be in the deck anymore.
