The expected value of the policy for the insurance company: $359.38

Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.

Probability of Event = Favorable Outcomes/Total Outcomes = X/n

The expected value of the policy for the insurance company can be calculated as follows:

Expected value = (Probability of survival) x (Annual payment)

= 0.999057 x $360

= $359.38

So, the expected value of the policy for the insurance company is $359.38.

It's important to note that this is just an estimate based on statistical probabilities and does not guarantee the outcome. The actual value could be higher or lower than this estimate, depending on the actual lifespan of the policyholder.

Answer:

x=70

Step-by-step explanation:

Since the lines are parallel, we know angle y

60 and y are alternate interior angles and alternate interior angles are equal when the lines are parallel

y=60

The sum of the angles of the triangle are 180

x+y = 50 =180

x+60+50 =180

x+110 = 180

x = 180-110

x = 70

Answer:

x=70 degrees!!!

Step-by-step explanation:

Given that the lines are parallel, we can deduce the measure of angle y. As per the property of alternate interior angles, angle y and the given angle measuring 60° are equal when two lines are parallel. Hence, y = 60°.

Now, considering the triangle, the sum of its interior angles is always 180°. Let's set up an equation to find the measure of angle x:

x + y + 50 = 180

Since we know y = 60°, we can substitute the value and simplify:

x + 60 + 50 = 180

Combining like terms:

x + 110 = 180

To find x, we subtract 110 from both sides:

x = 180 - 110

After calculation, we get:

x = 70°

Therefore, the measure of angle x is 70°.

By working with the given percentage, we will find that there are 1,050 students in the school.

First, we know that (66 + 2/3)% = (66.66...%) of the students are girls.

Then the remaining 33.33% are boys.

And we know that there are 350 boys, so the 33.33...% of the students is equal to 350.

So we can write the equations for percentages:

350 = 33.33%

X = 100%

Where X is the total number of students, to find X, we can take the quotient between these two equations:

X/350 = 100%/33.33%

X = 350/0.333... = 1,050

So there are 1,050 students on that school.

Step-by-step explanation:

The correct answer is B i.e. Standard Error of the Mean (SE) = σ / √(n)

The measure of the variability of the sample means, also known as the standard error of the mean, can be calculated using the formula:

Standard Error of the Mean (SE) = σ / √(n)

sigma is the population standard deviation,

n is the sample size.

The standard error of the mean represents the variability or dispersion of the sample means obtained from repeated samples of size n from a population. It indicates how much the sample means are likely to differ from the true population mean.

The smaller the standard error of the mean, the less variability is expected among the sample means, indicating a more precise estimate of the population mean.

t (total cost)= 1.75P or 1.75×p

To represent the total cost in dollars to pick 'p' pounds of strawberries, we can use the following expression Total cost = $1.75 * p

In this expression, 'p' represents the number of pounds of strawberries to be packed, and $1.75 represents the cost charged by the firm for each pound of strawberries.

To calculate the total cost, we multiply the cost per pound ($1.75) by the number of pounds ('p') to get the overall cost in dollars.

For example, if you want to pack 5 pounds of strawberries, you can substitute 'p' with 5 in the expression:

Total cost = $1.75 * 5

Total cost = $8.75

The surface area of the balloon is increasing at a rate of 5 square centimeters per second when the radius is 5 cm.

A) We know that the volume of a sphere is given by:

V = (4/3)πr^3

Taking the derivative of both sides with respect to time, we get:

dV/dt = 4πr^2 (dr/dt)

where dV/dt is the rate of change of volume (which is 10 cubic centimeters per second in this case), dr/dt is the rate of change of radius, and 4πr^2 is the surface area of the sphere.

Rearranging the equation, we get:

dr/dt = (1 / (4πr^2)) dV/dt

Substituting dV/dt = 10 cubic centimeters per second, we get:

dr/dt = (1 / (4πr^2)) (10) = (5 / (2πr^2)) cubic centimeters per second

Therefore, the expression for the rate at which the radius of the balloon is increasing is dr/dt = (5 / (2πr^2)) cubic centimeters per second.

B) When the diameter is 40 cm, the radius is 20 cm. We can use the expression we derived in part (A) to find the rate at which the radius is increasing:

dr/dt = (5 / (2πr^2)) cubic centimeters per second

Substituting r = 20 cm, we get:

dr/dt = (5 / (2π(20^2))) cubic centimeters per second

dr/dt ≈ 0.00198 cm/s (rounded to 5 decimal places)

Therefore, the radius of the balloon is increasing at a rate of approximately 0.00198 cm/s when the diameter is 40 cm.

C) When the radius is 5 cm, the surface area of the sphere is given by:

A = 4πr^2

Taking the derivative of both sides with respect to time, we get:

dA/dt = 8πr (dr/dt)

We can use the expression we derived in part (A) to find the rate at which the radius is increasing:

dr/dt = (5 / (2πr^2)) cubic centimeters per second

Substituting r = 5 cm and dr/dt = (5 / (2πr^2)) cubic centimeters per second, we get:

dA/dt = 8π(5) ((5 / (2π(5^2))))

dA/dt = 5 cubic centimeters per second

Therefore, the surface area of the balloon is increasing at a rate of 5 square centimeters per second when the radius is 5 cm.

By using triangle properties and the law of the cosine twice, we find that the distance between points M and N is approximately 9.8 meters.

In this problem we must determine the distance between two points that are part of a triangle and we can take advantage of properties of triangles to find it. First, we determine the measure of angle L by the law of the cosine:

\(\cos L = \frac{(19.6\,m)^{2}-(14.8\,m)^{2}-(21.4\,m)^{2}}{-2\cdot (14.8\,m)\cdot (21.4\,m)}\)

L ≈ 62.464°

Then, we get the distance between points M and N by the law of the cosine once again:

\(MN = \sqrt{(7.4\,m)^{2}+(10.7\,m)^{2}-2\cdot (7.4\,m)\cdot (10.7\,m)\cdot \cos 62.464^{\circ}}\)

MN ≈ 9.8 m

Subtract 20 from both sides of -3x-8y=20, so that it becomes -3x-8y-20

Subtract 19 from both sides of -5x+y=19, so you get -5x+y-19

Subtract like terms from both equations (-3x-8y-20)-(-5x+y-19), which gives you 2x-9y-1

-3--5=2, -8-1=-9, -20--19=-1

Add 1 to both sides and you get 2x-9y=1

This inequality means that the sum of "d" and "c" must be greater than or equal to 12.

What is algebraic expression ?

Algebraic expression can be defined as combination of variables and constants.

Let's represent the number of drinks Olivia buys as "d", and the number of candies as "c".

We know that Olivia must buy no less than 12 drinks and candies altogether. This means that the total number of drinks and candies purchased, d + c, must be greater than or equal to 12.

So the inequality that represents the possible values for the number of drinks purchased and the number of candies purchased is:

d + c ≥ 12

This inequality means that the sum of "d" and "c" must be greater than or equal to 12. For example, Olivia could buy 8 drinks and 4 candies, or 6 drinks and 6 candies, or 10 drinks and 2 candies, and so on, as long as the total number of drinks and candies is 12 or more.

Therefore, This inequality means that the sum of "d" and "c" must be greater than or equal to 12.
