Answer:
150 short-sleeved shirts100 long-sleeved shirtsStep-by-step explanation:
Let S and L represent the numbers of short- and long-sleeved shirts ordered.
The expected earnings were ...
5S +10L = 1750
The number sold was ...
(1/3)S + (1/2)L = 100
We can multiply the first equation by 1/5 and the second equation by 6 to put the equations into standard form:
S +2L = 3502S +3L = 600Subtracting the second equation from twice the first gives ...
2(S +2L) -(2S +3L) = 2(350) -(600)
L = 100 . . . . . . simplify
2S +3(100) = 600
S = 150
150 short-sleeved and 100 long-sleeved shirts were ordered.

Answer:
k = 6
Step-by-step explanation:
Since the figures are similar, we can use ratios to solve
4 28
----- = -------
k 42
Using cross products
4 * 42 = 28k
Divide each side by 28
4*42/28 = 28k/28
6 = k
Answer: k = 6mm
Step-by-step explanation:
The shapes are similar, which means that each side on the triangle is proportionally similar to its corresponding side on the other triangle.
We can use proportions to solve for k:
[tex]\frac{4}{28} = \frac{k}{42}[/tex]
4 and k are proportionally similar and 28 and 42 are proportionally similar.
You can then cross-multiply to get this:
28k = 168
k = 6
The missing side is 6 mm long.

The probability of receiving an offer from the Central Park Zoo is 48%. The probability of Daniel getting an offer from both SeaWorld and the Central Park Zoo is 15%.
Determine the probability of receiving an offer from either SeaWord or Central Park Zoo but not both. ____________
Answer:
[tex]68\%[/tex]
Step-by-step explanation:
Let A be the event that Daniel receives call from SeaWorld.
Probability of event A, P(A) = [tex]35\%[/tex]
Let B be the event that Daniel receives call from Central Park Zoo.
Probability of event B, P(B) = [tex]48\%[/tex]
Probability that Daniel receives calls from both SeaWorld and Central Park Zoo:
[tex]P(A \cap B) = 15\%[/tex]
We know that formula:
Probability that Daniel receives call from either SeaWorld or Central Park Zoo but not both:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)\\\Rightarrow P(A \cup B) = 35\% + 48\% - 15\%\\\Rightarrow P(A \cup B) = 68\%[/tex]
Hence, required probability is [tex]68\%[/tex].

A cylinder is 20 inches long and has a diameter of 10 inches. What is the approximate volume of the cylinder?
Answer:
V=π(d/2)^2·h
=π·(10/2)^2 · 20
≈1570.79633in³
this is the correct answer!!!
The approximate volume of the cylinder is 1570.796 inches³.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
A cylinder is a geometrical shape has two circular bases which are parallel and they are connected with a curved surface.
Given that,
Height of the cylinder = 20 inches
Diameter of the base = 10 inches
Radius = Diameter / 2 = 10/2 = 5 inches
Volume of the cylinder = π r² h, where r is the radius and h is the height.
Volume = π (5)² (20)
= 500π
= 1570.796 inches³
Hence the volume is approximately 1570.796 inches³.

An insurance policy charges a regular risk premium, , at Years 0,1,2,3,…,9 from today. The policy pays a claim of 2 (i.e. × ) in 15 Years from today. Calculate the value of (to 2 decimal places), assuming an interest rate of 2% per annum.
Answer:
x = 12.29
Step-by-step explanation:
present value of the claim = x² / (1 + 2%)¹⁵ = 0.743x²
present value of the 10 premiums:
x + x/1.02 + x/1.02² + x/1.02³ + x/1.02⁴ + x/1.02⁵ + x/1.02⁶ + x/1.02⁷ + x/1.02⁸ + x/1.02⁹ = x + 0.9504x + 0.9612x + 0.9423x + 0.9238x + 0.9057x + 0.888x + 0.8706x + 0.8535x + 0.8368x = 9.1323x
0.743x² = 9.1323x
x² / x = 9.1323 / 0.743
x = 12.29
Answer
x = 12.29
Step-by-step explanation:
Given that the policy claims x² in 15 years, at 2% = 0.02, the present value of the claim is given as:
x²/(1 + 0.02)^15
= x²(1/1.02)^15
= 0.743x²
The present value of the 10 premiums:
x + x/1.02 + x/1.02² + x/1.02^3 + x/1.02^4 + x/1.02^5 + x/1.02^6 + x/1.02^7 + x/1.02^8 + x/1.02^9
= x + 0.9504x + 0.9612x + 0.9423x + 0.9238x + 0.9057x + 0.888x + 0.8706x + 0.8535x + 0.8368x
= 9.1323x
Now,
0.743x² = 9.1323x
x²/x = 9.1323/0.743
x = 12.29
This is what we are looking for.
Use algebraic methods to find as many intersection points of the following curves as possible. Use graphical methods to identify the remaining intersection points.
r = 5 sinθ and r = 5 cosθ
Answer:
Step-by-step explanation:
r =5sin i
r=5 cos i
divide
tan i=1=tan (π/4),tan(π+π/4)
or tan i=tan (π/4),tan(5π/4)
or tan i=tan (2n π+π/4),tan (2nπ+5π/4)
or tan i=tan ((8n+1)π/4),tan((8n+5)π/4)
i=(8n+1)π/4,(8n+5)π/4
where n is an integer.
so we get infinite points of intersection.

Sphere V = 4

πr3
How much air can the beach ball hold?
Answer:
288π or 904.78
Step-by-step explanation:
We know that the diameter of this beach ball is 12 inches and we want to determine how much air it can hold using the formula for the volume of a sphere which is [tex]\frac{4}{3}[/tex] × π × r³ where 'r' is the radius. In the question we are given the diameter not the radius but we can half the diameter to find the radius so 12 ÷ 2 = 6. The radius of the beach ball is 6 inches so let's work out how much air it can hold.
Volume = [tex]\frac{4}{3}[/tex] × π × r³
→ Let's substitute in the values
Volume = [tex]\frac{4}{3}[/tex] × π × 6³
→ Simplify
Volume = [tex]\frac{4}{3}[/tex] × π × 216
→ Simplify further
Volume = 288π or 904.78
The amount of air can the sphere shape beach ball hold is 208π or 904.78 inches.
What is sphere?
The "set of all points in 3 dimensional space is lying the same distance from the given points or center" is called sphere.
According to the question,
Diameter of sphere shape beach ball is 12inches
Radius of sphere shape beach ball is 12/2 = 6inches
Volume of sphere = [tex]\frac{4}{3}[/tex] × π × r³
= [tex]\frac{4}{3}[/tex] × [tex]\frac{22}{7}[/tex] × (6)³
= 904.78inches
Hence, the amount of air can the sphere shape beach ball hold is 208π or 904.78 inches.

When playing roulette at the Venetian casino in Las Vegas, a gambler is trying to decide whether to bet $5 on the number 27 or to bet $5 that the outcome is any one of these five possibilities: 0, 00, 1, 2, 3. From Example 6, we know that the expected value of the $5 bet for a single number is -26. For the $5 bet that the outcome is 0, 00, 1, 2, or 3, there is a probability of 5>38 of making a net profit of $30 and a 33>38 probability of losing $5.
a. Find the expected value for the $5 bet that the outcome is 00, 0, or 1.
b. Which bet is better: a $5 bet on the number 25 or a $5 bet hat the outcome is any one of the numbers 00, 0, or 1? Why?
Answer:
Step-by-step explanation:
Given that:
To bet $5 that the outcome is any one of these five possibilities: 0, 00, 1, 2, 3.
Let Y represent the Amount of net profit
Then, Y= {-5, 30}
The probability distribution of Y is:
Y -5 30
P(Y=y) [tex]\dfrac{33}{38}[/tex] [tex]\dfrac{5}{38}[/tex]
a) The expected value of X is given by:
[tex]E[Y] =\sum y P(Y=y)= 30*\dfrac{5}{38}-5*\dfrac{33}{38}[/tex]
[tex]=-0.39[/tex]
[tex]= -39 \ cents[/tex]
b)
On a bet of $5 on the number 25 we are expected to loose 24 cents.
While on a $5 bet that the outcome is any one of the numbers 0,00, or 1 we are expected to loose 39 cents.
Hence, $5 bet on the number 27 is better. Because the expected loss is less in this bet

A circular swimming pool has a radius of 15ft. There is a path all the way around that pool that is three feet wide. What is the circumference of the outer edge of the path around the pool? Use 3.14 for pie
Answer:
94.2 ft.
Step-by-step explanation:
The equation to find circumference is 2 times pie times radius. We subsitute pie for 3.14. Now the equation is 2(3.14)r. The radius is 15. When we subsitute 15 for r the answer will be 2(3.14)15. Another way to write it is 2 times 3.14 times 15. The answer would be 94.2

If order matters, how many ways can he arrange his family members into a row of five seats if Jose must sit in the first seat?
O 35
O 840
O 1,680
0 2,620
Answer:
840
Step-by-step explanation:
Since the order matters, we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
The first seat is Jose's.
The remaining four are organized among the other 7 members. So
[tex]P_{(7,4)} = \frac{7!}{(7-4)!} = 840[/tex]
So the correct answer is:

a mini dvd has a radius of 4 centimeters. there is a hole in the middle of the mini dvd with a radius of 1 centimeter. what is the area of one side of the mini dvd
Answer:
Area of one side of mini DVD = 15π or 47.12 cm²
Step-by-step explanation:
The radius of the mini DVD is;r = 4cm.
Area of a circle = πr²
Thus, Area of mini DVD = π × 4² = 16π
Now,we are told the mini DVD has a hole with a radius of 1 cm.
Area of hole = π × 1² = π
To find the area of one side of the mini DVD, we have to subtract the area of the hole from the area of the DVD.
Thus;
Area of one side of mini DVD = 16π - π
= 15π = 47.12 cm²
