Answer:
2 hours.
Step-by-step explanation:
Money earned for 14 hours of life-guarding = 14*18 = $252. If he worked another 5 hours to make the maximum of 19 he would earn 252 + 5*9
= $297 but he wants to work a minimum of hours for a minimum of 270.
Thus we have the inequality:
252 + 9x ≤ 270
9x ≤ 18
x ≤ 2.
So the number of hours he must do clearing tables = 2.

Answer:
B. 11.000
Step-by-step explanation:
The function looks like a reflected and translated exponential function with a horizontal asymptote near y = 11.000. The rate of change is decreasing so fast that the next value is expected to be very near 10.994. The closest one among the answer choices is 11.000.
_____
First differences are 0.811 and 0.011. The latter is about 0.0136 times the former. At that rate of change, we expect the next first difference to be about 0.000149, which would make the next number in sequence be about 10.9941—very little change from 10.994.
Clearly, first differences are not constant, so the function is not linear. Ratios of the numbers are not constant, so this is not an exponential (geometric) sequence. A reflected exponential function of the type described is a good fit.
With only 3 points given, the rule is not at all obvious. The next term could legitimately be anything you like, and a rule could be made that would fit it.
Answer:
Mean is 17
Median is 10.5
Mode is 2
Range is 37
Step-by-step explanation:
<u>Mean is the average: 2 + 2 + 6 + 15 + 38 + 39 = 102 / 6 = 17 MEAN</u>
<u />
<u>Median is the middle: 2, 2, 6, 15, 38, 39</u>
Between 6 and 15 -> 15 - 6 = 9 / 2 = 4.5
6 + 4.5 = 10.5
Median is 10.5
<u>Mode is most common: </u><u>2, 2</u><u>, 6, 15, 38, 39</u>
<u />
Mode is 2
<u>Range is the difference between the highest and the lowest number: 39 - 2</u>
37
Range is 37
Answer:
55/11 by reducing this you see how many times 11 goes into 55 ( 5 times )
Step-by-step explanation:
Rate is an expression for a change of some unit per unit of time. For this problem, we find the rate of change of the price by a simple equation which is expressed as:
Rate = change in price / change in time
Rate = ($1.20/lb - $0.90/lb) / 5 yrs - 0
Rate = $0.06 per lb per year
Thus, the answer is B.
