Answer:
1054.00
Step-by-step explanation:
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.
What is 4+5 devices by two
The equation can be written as:
4 + 5 / 2
Remember to follow PEMDAS.
4 + 5 / 2
4 + 2.5
6.5
Best of Luck!
Answer:
If you mean whats 4+5/2 the answer is 6.5 because PEMDAS says to Divide first . So 4+(5/2). 5/2 is 2.5. so 4+(2.5) which equals 6.5
om is 5 years younger than his brother. If the sum of their ages is 43 years now, find their age.
Answer:
Brother's age =24
Om's age =19
Step-by-step explanation:
Let bro's age be x
Let om's age be x-5
x+x-5=43
2 x -5=43
2 x = 43+5

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
magine that you are conducting a one-variable chi-square test to investigate the hypothesis that there are equal numbers of cat lovers and dog lovers in the office at work. Having conducted a survey, you found 150 preferred dogs and 120 preferred cats. What would the expected frequencies be in each cell? 135 150 and 120 270 More information is needed to calculate the expected frequencies.
Answer:
a. 135 is correct
Step-by-step explanation:
We have the following information:
dogs lover: 150
cats lover: 120
as the null hypothesis:
H, there are equal number of dogs lover and cats lover, so the expected frequency in each cell will be equal and that is:
f = (150 + 120) / 2
f = 270/2 = 135
so option a. 135 is correct

Answer:
The cop = 40 and the baseball cap = 3 and the baseball bat = 21
Step-by-step explanation:
So 40 - 21 + 3(2) = 25
Answer:
25
Step-by-step explanation:
look at the whole thing first. you see that the field = player so first you do 120/3. you get 40. then for teh second you have two "40's" and an unknown. so you do 101-80 because 40+40=80 and get 21. for the fourth you have 21/?=7 . we can do 21/7=3 to find this. so the helmet is 3. for the final we have 40-21+6 and that equals 25. thank you ;)
The diameter of this beach ball is 12 inches.

Apply the formula for the volume of a sphere to determine how much air it can hold. Use the calculator to multiply by π. Round to the nearest hundredth.
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.

p + nx=rx-e (solve for x)
Answer:
(p+e)/(r-n) = x
Step-by-step explanation:
p + nx=rx-e
Add e to each side
p +e+ nx=rx-e+e
p +e+ nx=rx
Subtract nx from each side
p +e+ nx - nx=rx-nx
p+e = rx -nx
Factor out x
p+e = x(r-n)
Divide each side by (r-n)
(p+e)/(r-n) = x(r-n)/(r-n)
(p+e)/(r-n) = x

If parallelogram ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A' lie?
[Hint: Place your coordinates in the blank with no parentheses and a space after the comma in the form: x, y]
Parallelogram ABCD is shown.
A is at negative 4, 1.
B is at negative 3, 2.
C is at 0, 2.
D is at negative 1, 1.
Answer:
(Fill in the blank)
Answer:
A' is at (-4, 1)
Step-by-step explanation:
Reflection over both axes is equivalent to rotation by 180°. Then rotation by 180° returns the point to its original location. The original location of point A is (-4, 1), so the location of its image is A'(-4, 1).
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

The volume of a sphere is 904.32 cubic millimeters. What is its radius?
Hello!
Answer:[tex]\boxed{ \bf The~radius~of~the~sphere~is~6~mm.}[/tex]
Explanation:We know that:
V = [tex]\frac{4}{3}[/tex]πr³
904.32 = [tex]\frac{4}{3}[/tex]πr³
To figure out the radius, we have to undo the above. We can undo the fraction by multiplying by it's reciprocal:
[tex]\frac{3}{4}[/tex] × [tex]\frac{904.32}{1}[/tex] = [tex]\frac{4}{3}[/tex]πr³ × [tex]\frac{3}{4}[/tex]
678.24 = πr³
Next, we're going to divide both sides by pi:
[tex]\frac{678.24}{\pi } = \frac{\pi r^{2} }{\pi }[/tex]
215.90 = r³
To undo the, we must find the cube root of 215.90.
r = 6
Answer:
[tex]radius = 6mm[/tex]
Step-by-step explanation:
Volume of a sphere.
Use this formula
[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]
Now solve for r
[tex]r = (3 \frac{v}{4\pi} ) ^{ \frac{1}{3} } \\ = (3 \times \frac{904.32}{4 \times \pi} ) ^{ \frac{1}{3} } \\ ≈
5.99899mm
