C. Permanent life insurance policies insure policy holders for as long as they pay a premium, is a true statement.

Permanent life insurance is a type of life insurance policy that provides coverage for the policyholder's entire life, as long as they continue to pay the premium. Unlike term life insurance, which provides coverage for a specified period of time, permanent life insurance is designed to last for the duration of the policyholder's life, as long as they pay the required premiums.

Option A is not correct because permanent life insurance policies require ongoing premium payments, not an upfront payment.

Option B is not correct because permanent life insurance tends to be more expensive than term life insurance, especially for younger policyholders.

Option D is not correct because permanent life insurance tends to be more expensive for older policyholders, due to the higher likelihood of the policyholder passing away, which means the insurance company will have to pay out the death benefit sooner.

Answer:

The value of x is 3.2 cm.

Step-by-step explanation:

We know that the diameter of the circle is 9 2/5 cm. We also know that the diameter of a circle is twice the length of its radius. Therefore, we can write:

2(radius) = diameter

2(x + 1.5) = 9 \ 2/5

Multiplying both sides by 5 to get rid of the fraction, we get:

2(x + 1.5) * 5 = 9 * 5 + 2

10(x + 1.5) = 47

Dividing both sides by 10, we get:

x + 1.5 = 4.7

Subtracting 1.5 from both sides, we get:

x = 4.7 - 1.5

x = 3.2

Therefore, the value of x is 3.2 cm.

Humanity would achieve a life expectancy of 110 years in approximately 60 years.

To calculate the number of years it would take for humanity to achieve a life expectancy of 110 years, we need to determine the number of decades required to reach this goal based on the given rate of increase.

In 2009, the life expectancy was about 80 years. From that point, we need to calculate the difference between the current life expectancy and the target life expectancy of 110 years.

110 years - 80 years = 30 years

Since the rate of increase is 5.3 years every decade, we can divide the difference by the rate to determine the number of decades required:

30 years / 5.3 years per decade ≈ 5.66 decades

Since we can't have a fraction of a decade, we need to round up to the nearest whole number. Therefore, it would take approximately 6 decades for humanity to achieve a life expectancy of 110 years.

To calculate the number of years, we multiply the number of decades by 10:

6 decades * 10 years per decade = 60 years

The median number of hours slept by boys the previous night is 6.5 hours, while the median number of hours slept by girls the previous night is 7 hours.

The given line plots display the results of a survey of 10 boys and 10 girls regarding the number of hours they slept the previous night. To find the median, follow these steps:Put the observations in ascending order.Divide the data into two equal parts.

To locate the median of the data, find the value that is at the center of the data when ordered.To calculate the medians of the given line plots, we must first arrange the observations in ascending order and divide them into two equal parts.

We have 10 boys and 10 girls in total, so we will have 20 observations for each line plot: Boys’ line plot: 4, 5, 6, 6, 6, 7, 7, 8, 9, 10Girls’ line plot: 5, 5, 6, 7, 7, 7, 7, 8, 8, 10When arranged in ascending order,

the observations are as follows: Boys’ line plot: 4, 5, 6, 6, 6, 7, 7, 8, 9, 10Girls’ line plot: 5, 5, 6, 7, 7, 7, 7, 8, 8, 10 Now,

we must determine the medians for each data set. Since each data set has an even number of observations, the median is the average of the two middle values.

The medians for each data set are as follows: Boys’ line plot: (6 + 7) / 2 = 6.5Girls’ line plot: (7 + 7) / 2 = 7

The number of revolutions made by the wheel is 5.24 ≅ 5.  

One complete revolution is equal to 360 degrees, so to find the number of complete revolutions the wheel has made, we can divide the total number of degrees rotated by 360.    

Here we have

A wheel rotated by 1888°  

As we know One complete revolution is equal to 360 degrees

Hence, the angle can be rotated by the wheel in 1 rotate = 360°  

Let the wheel make 'x' revolution to make 1888°  

=> 360(x) = 1888

=> x = 1888/360

=> x = 5.24

Therefore,

Answer and Explanation:

A confidence interval determines the probability that a range of values(e.g-given a large data set )has the true parameter. Example, to find mean of height of 30+ men, our confidence interval will say that there is 96% confidence that the mean height of 30+ men is between 5ft and 6ft. While confidence intervals, narrow or broad with high or low significance levels may not be akin to accuracy, it will only help to determine the precision or otherwise of our estimate. For example, if confidence interval is narrow as in second option and confidence level is lower, it only narrows down our options to ascertain the true mean or parameter we are investigating and doesn't exactly affect accuracy since we are still not 100% confident our true mean lies in this interval.

The value of angle x and angle y is determined as 78⁰ and 115⁰ respectively.

The value of angle x and angle y is calculated by applying principle of angles formed by parallel lines as follows;

The value of angle adjacent x = 102⁰

The value of angle x   is calculated as;

x = 180 - 102 ( sum of angles on a straight line)

x = 78⁰

The value of angle y is calculated as follows;

y = 115⁰ (corresponding angles are equal)

Thus, the value of angle x and angle y is determined as 78⁰ and 115⁰ respectively.

Answer: (6,-6)

Step-by-step explanation:

To find the coordinates of point B, we can use the midpoint formula:

Midpoint formula: The midpoint M of a line segment with endpoints (x1, y1) and (x2, y2) is given by:

M = ((x1+x2)/2, (y1+y2)/2)

Here, we know that the midpoint M is (4, -2), and one endpoint A is (2, 2). Let B be the other endpoint, so we can use the midpoint formula to find B:

4 = (2+x2)/2 --> 8 = 2+x2 --> x2 = 6

-2 = (2+y2)/2 --> -4 = 2+y2 --> y2 = -6

Therefore, point B has coordinates (6, -6).

As for the second question, without a graph or information about the equation of line t and point P, it is not possible to determine which points lie on the line passing through P and perpendicular to t.

The ratio of the volume of water in Jug B to the volume of water in Jug C is 35:18.

Let's assume the volume of water in Jug B is x.

According to the given information, Jug A contains 6/7 as much water as Jug B. Therefore, the volume of water in Jug A can be calculated as (6/7) * x.

Similarly, Jug C contains 3/5 as much water as Jug A. Hence, the volume of water in Jug C can be expressed as (3/5) * [(6/7) * x].

To find the ratio of the volume of water in Jug B to the volume of water in Jug C, we divide the volume of water in Jug B by the volume of water in Jug C:

(x) / [(3/5) * (6/7) * x]

Simplifying the expression, we get:

x / (18/35 * x)

The x values cancel out, leaving us with:

1 / (18/35)

To simplify further, we multiply the numerator and denominator by the reciprocal of the denominator:

Step-by-step explanation:

As given, A disc jockey has 2 types of files :

1 : Albums

2 : Singles

Given that , in every album there is 14 songs

as we have 277 albums

So, total numbers of songs in 277 albums = 277×14 = 3878 songs    ........(1)

Now,

Given that, in each singles there is 1 song

As we have 177 singles

So, total number of songs in 177 singles = 177×1 = 177 songs      ..........(2)

So, the total numbers of songs disc jockey have = Total number of songs in 277 albums + total number of songs in 177 singles

⇒The total numbers of songs disc jockey have = 3878 + 177

                                                                               = 4055 songs

Black probability 50%

Step-by-step explanation:

Hope this helps! Brainliest would be much appreciated! Have a great day! :)

The probability that Bill takes out a black or a shirt is 0.8, or 80%

We can use the following formula to calculate the probability that the piece of clothing Bill takes out is black or a shirt:

P(black or shirt) = P(black) + P(shirt) - P(black and shirt)

P(black) is the probability that the piece of clothing is black.

P(shirt) is the probability that the piece of clothing is a shirt.

P(black and shirt) is the probability that the piece of clothing is both black and a shirt.

The probability that the piece of clothing is black is 4 / 10 = 0.4. The probability that the piece of clothing is a shirt is 6 / 10 = 0.6. And the probability that the piece of clothing is both black and a shirt is 2 / 10 = 0.2.

So, the probability that the piece of clothing Bill takes out is black or a shirt is:

P(black or shirt) = 0.4 + 0.6 - 0.2
