-4
Answer:
1/4
Step-by-step explanation:
1. To find the slope, you can use the formula [tex]\frac{rise}{run}[/tex] to find it!
2. Rise means how many units you go up and down from point to point, and run means how far you go left or right from point to point.
3. Given the statement above, the rise would be 1, and the run would be 4.
4. Now, since slope is (rise)/(run), the slope is 1/4 because one divided by four is equal to one fourth.

It takes an elevator 2 seconds to go from floor to floor. Each passenger
takes 1.5 to 2.0 seconds to board or exit. Twelve passengers board on the
first floor and exit on the fourth floor. How long will you wait if you are on
the seventh floor and ring for the elevator just as it leaves the first floor?
Answer:
38 seconds
Step-by-step explanation:
just take 2x7 for the elevator taking the time to reach your floor which is 14 seconds. then just add on the additional time that all the passengers take to get off the elevator as it's only counting the time since it starts moving. that is 12x2=24. now just add 24+14 and you get your answer of 38

Answer:
$1200 each month
Step-by-step explanation:
So Craig pays $720 each year, so he pays 720/12 = $60 each month
Since $60 is 1/20 of his monthly income, we multiply 60 by 20
60* 20 = 1200
Craig earns $1200 each month

Find sine, where is the angle shown.
Give an exact value, not a decimal approximation.
Answer:
[tex] \sin( \theta) = \frac{opp}{hyp} \\ {c}^{2} = {a}^{2} + {b}^{2} \\ {c}^{2} = {8}^{2} + {15}^{2} \\ = 64 + 225 = 289 \\ c = \sqrt{289} \\ c = 17 \\ \sin( \theta) = \frac{15}{17} = 0.882 \\ \theta = { \sin}^{ - 1} (0.882) \\ \theta = 66.88 \degree\approx 67\degree[/tex]

Find the Mean, Median, Mode & Range. If possible, round to the nearest tenth. 3, 8, 7, 2, 4, 8, 3, 4
Answer:
Mean- 4.9
Median- 4
Mode- 3,4,8
Range- 6
Step-by-step explanation:
The mean of a sequence is the average amount. This is equal to all of the terms' sum divided by the number of terms. So, to find the mean add 2+3+3+4+4+7+8+8, which equals 39. Then, divide by 8 because that is the number of terms. Therefore, the mean is 4.9.
The median is the number in the middle of the sequence. To find the median order the sequence from least to greatest and find the middlemost number. In this case, that is 4.
The mode is the number that appears most often. In this sequence, 3, 4, and 8 all appear twice.
The range is the difference between the minimum and maximum. So, subtract 2 from 8 to get 6.
