Agata [3.3K]2 years ago
7 0

Answer:

3p = 1/2

Step-by-step explanation:

  1. Left side: 3p
  2. Right side: 1/2
  3. Because they're balanced, the right and left side are equaled
  4. So, 3p = 1/2

I hope this helps!

The table shows the number of people per day who died from SARS in Singapore at two-week intervals beginning on March 1, 2003.
julia-pushkina [17]

Answer:

Step-by-step explanation:

check attachment for chart

(a) When a data set is given, the area can be calculated using either left Riemann sum (when we use left end points of each interval) or right Riemann sum (when we use right end points of each interval).

Here the intervals are:

|----------------Interval---------------||----left point--||--right point---|

March 1 - March 15 (t0 to t1) : y0 = 0.0079, y1 = 0.0638

March 15 - March 29 (t1 to t2) : y1 = 0.0638, y2 = 0.1944

March 29 - April 12 (t2 to t3) : y2 = 0.1944, y3 = 0.4435

April 12 - April 26 (t3 to t4) : y3 = 0.4435, y4 = 0.5620

April 26 - May 10 (t4 to t5) : y4 = 0.5620, y5 = 0.4630

May 10 - May 24 (t5 to t6) : y5 = 0.4630, y6 = 0.2897

Hence total no. of deaths using left end point:

= y0.\bigtriangleup t + y1.\bigtriangleup t + y2.\bigtriangleup t + y3.\bigtriangleup t + y4.\bigtriangleup t + y5.\bigtriangleup t (\bigtriangleup t = 14 days)
\\\\=(y0 + y1 + y2+ y3 + y4 +y5).\bigtriangleup t
\\\\=(0.0079 + 0.0638 + 0.1944 + 0.4435 + 0.5620 + 0.4630) (14) = 24.2844 \approx 25 deaths (taking next integer value)


And total no. of deaths using right end point:

= y1.\bigtriangleup t + y2.\bigtriangleup t + y3.\bigtriangleup t + y4.\bigtriangleup t + y5.\bigtriangleup t + y6.\bigtriangleup t (\bigtriangleup t = 14 days)
\\\\=(y1 + y2+ y3 + y4 + y5 + y6).\bigtriangleup t
\\\\=(0.0638 + 0.1944 + 0.4435 + 0.5620 + 0.4630 + 0.2897) (14) = 28.2296 \approx 29 deaths (taking next integer value)

b)  If we are given derivative of a function f(t) as a function of time, that is:

\frac{\mathrm{d} }{\mathrm{d} t} (f(t)) = f'(t)


then the function can be evaluated by integrating both the sides. That is:

f(t) = \int f'(t) dt


And by definition we know that integration of a curve gives area under the curve. Hence if we have data for SARS deaths per day (i.e. derivative of total deaths as a function of time) then, if this data is plotted on a curve, area under this curve will give us total no. of deaths during a time period.

I need help on both problems.
matrenka [14]
1) Let, the original price = x
We know, sale price is 100 - 15 = 85% of original price.
So, x * 85% = 59
x * 0.85 = 59
x = 59/0.85
x = 69.41

In short, Your Answer would be Option B

2) Let, the original price = x
We know, sale price is 100 - 30 = 70% of original price.
x * 70% = 79
x * 0.70 = 79
x = 79/0.70
x = 112.85

In short, Your Answer would be $112.85

Hope this helps!

the perimeter of a rectangular picture frame is 32 inches.the length of the frame is 2 inches longer than the width. what are th
AleksAgata [21]

Answer:

The width is 7 inches and the length is 9 inches

Step-by-step explanation:

So we can divide 32 by 2 because we know perimeter is 2(l*w)

So it becomes 16, and it is now (l*w)

We know that the length is 2 inches longer so we subtract 2 from 16.

It then becomes 14 inches so therefore we can then divide it by 2.

14 divided by 2 is 7 and therefore we add 2 because we subtracted the two from earlier temporarily.

Therefore the width is 7 and the length is 9.
