Answer:
y = (1/2)x - 3 Answer A is closest.
Step-by-step explanation:
Two points on the line are (0, -3) and (4, -1). Notice that I've intentionally chosen "nice" points whose coordinates are integers; this makes the math easier. The point (1, -5/2) is also on the line if you want to use it, but the math's a bit more complicated.
Going from (0, -3) to (4, -1), x increases by 4 and y increases by 2. Hence, the slope of this line is m = rise / run = 2/4, or m = 1/2.
The slope-intercept formula for the equation of a straight line is the most convenient to use here, since we can tell immediately from the graph that the y-intercept is (0, -3):
y = (1/2)x - 3
Answer A should be y = (1/2)x - 3 for improved legibility. 1 2 x is not correct as a way to express (1/2)x.
Answer:
95% confidence interval: (2.784,3.176)
Step-by-step explanation:
We are given the following information in the question:
Sample size, n = 25
Sample mean = $2.98
Standard error = $0.10
Alpha = 0.05
95% confidence interval:
Putting the values, we get,
$45 - 15% = $38.25
$53 - 20% = $42.04
So the Forever 21 dress would cost less.
Hope this helped.
Answer:
Not enough info
Step-by-step explanation:
Find the length from the school to the community center (this is the shortest route).
2^2+7^2 = c^2
c = sqrt(53)
The amount of time the trip takes depends on how long it takes Miguel to walk one city block.
sqrt(53)*lengthOfTimeForOneCityBlockInMinutes = the minimum time.
If Jayden needs 900, and he already has 375, first you need to find out how much more money he needs. Do that first.
2. His job pays him 155 a week, so 155w. If he needs to make at least 900, that means that it would be ok if he earned equal to 900, or more. So the amount he earns is greater than or equal to 900.
3. Solve for w. This should give you your answer.
I hope this helps!
