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

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.

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].

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

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.

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.

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.

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.

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:

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

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

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.

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.
