Answer:

The number of people who like winter season is 1000.

Step-by-step explanation:

Event event correspond to a set in the Venn diagram, and we use it to find the percentages.

I am going to say that:

Event A: Like summer season

Event B: Like winter season.

55% like summer season

This means that $P(A) = 0.55$

20% like winter season

This means that $P(B) = 0.2$

40% don't like both seasons

This means that 100% - 40% = 60% like at least one, which means that $P(A \cup B) = 0.6$

Proportion who like both:

This is $P(A \cap B)$ . The measures are related by the following equation:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

$P(A \cap B) = P(A) + P(B) - P(A \cup B)$

Using what we have

$P(A \cap B) = 0.55 + 0.2 - 0.6 = 0.15$

750 like both seasons.

This is 15% of the sample. So the total number of people is t, for which:

$0.15t = 750$

$t = \frac{750}{0.15}$

$t = 5000$

20% like winter season

Out of 5000. So

0.2*5000 = 1000

The number of people who like winter season is 1000.

The circumference of a circle with an area of 1,809.56 square centimeters

Virty [35]

$\bf \textit{area of a circle}\\\\
A=\pi r^2~~
\begin{cases}
r=radius\\
------\\
A=1809.56
\end{cases}\implies 1809.56=\pi r^2
\\\\\\
\cfrac{1809.56}{\pi }=r^2\implies \boxed{\sqrt{\cfrac{1809.56}{\pi }}=r}\\\\
-------------------------------\\\\
\textit{circumference of a circle}\\\\
C=2\pi r\qquad \qquad \implies C=2\pi \left( \boxed{\sqrt{\cfrac{1809.56}{\pi }}} \right)$

uhammad, a shipping and receiving clerk, uses 1 yard, 2 feet, 4 inches of twine to wrap each carton he packs. He has to pack 29

irina1246 [14]

Answer

Find out the how much twine will he needs to pack 29 cartons today .

To proof

As given

uhammad, a shipping and receiving clerk, uses 1 yard, 2 feet, 4 inches of twine to wrap each carton he packs.

As given in the question

Convert the answer to larger units .

As between yard is the largest unit between yard, feet and inches.

$1 inches = \frac{1}{36} yard$

and

$1 feet = \frac{1}{3} yard$

Convert 2 feet into yard

$=\frac{2}{3}$

Convert 4 inches into yard

$= \frac{4}{36}$

twine to wrap each carton packs

$= 1 + \frac{2}{3} + \frac{4}{36}$

L.C.M of (3 , 36) = 36

than the equation becomes

$=\frac{36 +2\times 12 + 4}{36}$

$= \frac{64}{36}$

=1.77777778 yard

Now twine to wrap pack 29 cartons = 29× 1.77777778

= 51.5555556 yard

Now twine to wrap pack 29 cartons is 51.55 yard ( approx)

Hence proved

Tickets for the basketball game were sold at $4.00 for adults and $2.50 for students. If 320 tickets were sold for a total of $1

makkiz [27]

The problem based on condition are solved using the unknown variables. The number of tickets sold to the student are 120 and the number of tickets sold to the adults are 200.

Given information-

The price of the tickets for the basketball game for adults is $4.00.

The price of the tickets for the basketball game for students is $2.50.

<h3>Variables</h3>

Variables are the unknown and the value of the variables depend on the other variables in the equation. The above problem can be solved defining the variables from the given condition.

Let the total tickets purchased by the students is<em> x</em> and the total tickets porches by the adults is <em>y.</em>

As the total tickets sold for the game is $320. Thus,

$\begin{aligned}\\
x+y&=320\\
y&=320-x\\
\end$ .......1
