Let x be the precent
24 * x = 4
x = 4/24
x = 1/6
=1/6 * 100% = 16.67%

The diagram rerpesents responses to a survey that include statements p and q . Which statement is true?

BARSIC [14]

Answer:

C. The number of responces $p\vee q$ is also 46

Step-by-step explanation:

Note that:

$p\wedge q$ means both p and q must hold;
$p\vee q$ means either p or q must hold.

From the diagram,

the number of responses $p\wedge q$ is 46;
the number of responces $p\vee q$ is also 46;
the number of responces $p\setminus q$ is 0;
the number of responces which are neuther p nor q is 20.

So, you can state that the correct answer is C

The owner of a grocery store finds she can sell about 982 gallons of milk in a week if she prices it at $2.99 per gallon. If she

julia-pushkina [17]

Answer:

g = -1110p +4300.9
804 gallons

Step-by-step explanation:

a) Price is the independent variable, so the data we are given can be written as ...

(price, gallons) = (2.99, 982) and (2.79, 1204)

Using the 2-point form of the equation for a line, we have ...

g = (g2 -g1)/(p2 -p1)(p -p1) +g1

g = (1204 -982)/(2.79 -2.99)(p -2.99) +982

g = -1110(p -2.99) +982 = -1110p +4300.9

g = -1110p +4300.9

__

b) When p = 3.15, the predicted sales volume is ...

g = -1110(3.15) +4300.9 = 804.4

Weekly sales are predicted to be 804 gallons at a price of $3.15.

The daily average temperature in Santiago, Chile, varies over time in a periodic way that can be modeled approximately by a trig

natali 33 [55]

Answer:

a) the trigonometric function is;

$y = 7.5 sin ( \frac{2 \pi}{365}t + \frac{337 \pi}{730})+ 21.5$

b) $y = 28.36^0 \ C$ ( to two decimal places)

Step-by-step explanation:

This data can be represented by the sinusoidal function of the form :

$\mathbf{y = A sin (Bt -C)+D}$

where A = amplitude and which can be determined via the formula:

$A = \dfrac{largest \ temperature - lowest \ temperature}{2}$

$A = \dfrac{29-14}{2}$

$A = \dfrac{15}{2}$

A = 7.5° C

where B = the frequency;

Since the data covers a period of 3 days ; then $\dfrac{2 \pi}{B } =365$

$B = \dfrac{2 \pi}{365}$ ( where 365 is the time period )

The vertical shift is found by the equation D;

D = $\frac{largest \ temperature + lowest \ temperature}{2}$

D = $\frac{29+14}{2}$

D = 21.5

Replacing the values of A ; B and D into the above sinusoidal function; we have :

$y = 7.5 sin (\frac{2 \pi}{365}t -C) + 21.5$

From the question; when it is 7th of the year ( i.e January 7);

t = 7 and the temperature (y) = 29° C

replacing that too into the above equation; we have:

$29= 7.5 sin (\frac{2 \pi}{365}*7 -C) + 21.5$

$29= 7.5 sin (\frac{14 \pi}{365} -C) + 21.5$

$\frac{29-21.5}{7.5}= sin (\frac{14 \pi}{365} -C)$

$1= sin (\frac{14 \pi}{365} -C)$

$sin^{-1}(1)= (\frac{14 \pi}{365} -C)$

$\frac{\pi}{2}= (\frac{14 \pi}{365} -C)$

$C= (\frac{14 \pi}{365} -\frac{\pi}{2})$

$C= (\frac{28 \pi- 365 \pi}{730} )$

$C= \frac{-337 \pi}{730}$

Thus; the trigonometric function is;

$y = 7.5 sin ( \frac{2 \pi}{365}t + \frac{337 \pi}{730})+ 21.5$

Similarly; to determine the temperature o Jan 31; i.e when t= 31 ; we have :

$y = 7.5 sin ( \frac{2 \pi}{365}*31+ \frac{337 \pi}{730})+ 21.5$

$y = 7.5 sin ( \frac{62 \pi}{365}+ \frac{337 \pi}{730})+ 21.5$

$y = 7.5 sin ( \frac{124 \pi+ 337 \pi }{730})+ 21.5$

$y = 7.5 sin ( \frac{461 \pi }{730})+ 21.5$

$y = 7.5 *( 0.915)+ 21.5$

$y = 6.8689+ 21.5$

$y = 28.36^0 \ C$ ( to two decimal places)

A rectangular swimming pool is 19 meters long, 13 1 2 meters wide, and 1 1 2 meters deep. What is its volume?

Whitepunk [10]

Answer:

The volume of the rectangular swimming pool is $384.75\ m^{3}$ or $384\frac{3}{4}\ m^{3}$

Step-by-step explanation:

we know that

The volume of the rectangular swimming pool is equal to

$V=LWH$

we have

$L=19\ m$

$W=13\frac{1}{2}\ m=\frac{13*2+1}{2}=\frac{27}{2}\ m$

$H=1\frac{1}{2}\ m=\frac{1*2+1}{2}=\frac{3}{2}\ m$

substitute

$V=(19)(\frac{27}{2})(\frac{3}{2})$

$V=\frac{1,539}{4}=384.75\ m^{3}$

Convert to mixed number

$384.75=384\frac{3}{4}\ m^{3}$
