Answer:
1) A. 5 + 2.75 * S ≤ 21
2) 5
Step-by-step explanation:
Well there is an initial price of $5 and $2.75 per stop, and she can only spend less than or equal to $21 we can make the following inequality,
5 + 2.75 * S ≤ 21,
<em>Meaning, Q.1 is A</em>
<em />
Now #2 is 5 stops because if we plug in 5 for s we get 18.75.
<em>Thus, the most amount of stops she can afford is 5.</em>
<em />
<em>Hope this helps :)</em>

Step-by-step explanation: 5 - 1 = 4
Answer:
90% confidence interval for the mean blood pressure of all executives is 123.12 to 129.02.
The closest option is A
Step-by-step explanation:
Confidence Interval = mean + or - Error margin (E)
mean = 126.07
sd = 15
n = 72
degree of freedom = n - 1 = 72 - 1 = 71
Confidence level (C) = 90% = 0.9
Significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
t-value corresponding to 71 degrees of freedom and 10% significance level is 1.6667
E = t×sd/√n = 1.6667×15/√72 = 2.95
Lower limit = mean - E = 126.07 - 2.95 = 123.12
Upper limit = mean + E = 126.07 + 2.95 = 129.02
90% confidence interval for the mean blood pressure of all executives is between a lower limit of 123.12 and an upper limit of 129.02.
Answer:
B : a 20% increase in variable costs
Step-by-step explanation:
Here the industry is seeing a 20% increase in activity levels over the fourth quarter. Since, there has been an increase in activity levels the fixed cost would remain the same but the variable cost being variable would increase with increase in production activity in same proportion as the increase in production.
B : a 20% increase in variable costs
<span>Start with a line segment PQ.<span>1Place the compasses on one end of the line segment.</span><span>2Set the compasses' width to a approximately two thirds the line length. The actual width does not matter.</span><span>3Without changing the compasses' width, draw an arc above and below the line.</span><span>4Again without changing the compasses' width, place the compasses' point on the the other end of the line. Draw an arc above and below the line so that the arcs cross the first two.</span><span>5Using a straightedge, draw a line between the points where the arcs intersect.</span><span>6Done. This line is perpendicular to the first line and bisects it (cuts it at the exact midpoint of the line).<span>
