Answer:

[tex]a = \frac{1296}{5\pi} [/tex]

Step-by-step explanation:

Given:

C = 14,4 (circumference)

Find: A - ? (area)

Let's start by writing down both circumference and area formulas:

[tex]c = 2\pi \times r[/tex]

[tex]a = \pi \times {r}^{2} [/tex]

We can find the radius (r) from the 1st formula:

[tex]r = \frac{c}{2\pi} = \frac{14.4}{2\pi} =14 \frac{4}{10} \times \frac{1}{2\pi} = \frac{144}{10} \times \frac{1}{2\pi} = \frac{144}{20\pi} = \frac{36}{5\pi} [/tex]

Now, that we know the length of the radius, we can find the area:

[tex]a = \pi \times( { \frac{36}{5\pi} })^{2} = \frac{1296}{25 {\pi}^{2} } \times \frac{\pi}{1} = \frac{1296}{25\pi} [/tex]

No, she have not enough time to fill the pool before he gets home. The garden hose with flow rate 24 gal/min will take 40 minutes to complete fill up the tank that is t ~ 40 minutes. So, she cannot complete fill up the pool before he come.

We have, the time in which Ines's younger brother will be home = an half hour = 1/2 hour

water flow rate of garden's hose = 24 gal/min

She want to fill up the pool. From the figure, depth of pool = 3 ft

Width of pool = 10 in.

1 inch = 0.0833 feet

So, 10 inches = 0.833 feet

outer diameter of pool = 9 ft

so, outer radius of pool = 4.5 ft

Now, inner diameter of pool/tank = outer diameter - 2(width)

= 9 - 2×0.833

= 9 - 1.666 = 7.334

Inner radius of pool = 7.334/2 = 3.667 ft

Water flow rate, Q = 24 gal/min

= 24/7.48 gal ( since 1 ft³ = 7.48 gal)

= 3.20 ft³

Using formula, Q = volume/ time

where t --> time to fill up the pool through hose

Volume of tank/pool = surface area × height (depth)

= π r² × h , where r is inner radius

= π (3.667)² × 3 ft³

= 126.71 ft³

So, Q = 126.71 ft³/t

=> t = 126.71 ft³/3.20 ft³

=> t = 39.59 min

Hence, required time is 39.59 ~ 40 minutes and she cannot complete before he come.

If your friend went to bed at 1:00am on Friday and woke up at 1:00pm on Friday, she slept for 12 hours.

To see why, you can count the number of hours between 1:00am and 1:00pm:

1:00am to 2:00am = 1 hour

2:00am to 3:00am = 1 hour

...

11:00am to 12:00pm = 1 hour

12:00pm to 1:00pm = 1 hour

The total number of hours between 1:00am and 1:00pm is 12 hours.

Answer:

  8.5 years

Step-by-step explanation:

You want to know the number of years until 18500 depreciates to 9100 at the rate of 8% per year.

The depreciation rate given as a percentage of current value tells you the depreciation is exponential. The formula will be ...

  value = (initial value) × (1 - (depreciation rate))^t

where the rate is "per year" and t is in years.

  value = 18500·(1 -0.08)^t

  9100 = 18500·0.92^t . . . . fill in the value of interest

  9100/18500 = 0.92^t . . . . divide by 18500

  log(91/185) = t·log(0.92) . . . . take logarithms

  t = log(91/185)/log(0.92) ≈ -0.3081/-0.03621 ≈ 8.509

It will be about 8.5 years until the value is $9100.

We find it fairly easy to locate an x-intercept, so we wrote the equation in the forms that makes the x-intercept the solution.

The equation of line perpendicular to y = -4x and passing through the point (12, 6) is y = 1/4 x + 3.

Using the slope method, determine the slope.

To find the y-intercept (b), use the slope and one of the locations.

You can obtain the equation for a line by entering the values of m and b into the slope-intercept form of the line (y = mx + b).

The given equation is y = -4x and we need to find the equation of the line which is passing through the point (12,6).

As y=-4x, therefore compared to the standard equation y = mx, hence the slope of the line is m = -4.

Therefore any line which is perpendicular and has a slope that is the negative reciprocal of the -4 is 1/4.

The modified equation becomes for the line that passes through (12, 6).

y-6 = 1/4 (x-12)

solving this equation we get,

y-6 = 1/4 x - 1/4 * 12

y-6 = 1/4 x - 3

y = 1/4 x -3 + 6

y = 1/4 x + 3

Therefore option 4 is correct, y = 1/4 x + 3

The Saints had the best overall record for the season because they had a larger mean value of about 200 points, whereas the Saints had a larger median value of 12 points.

To determine which team had the best overall record for the season, we need to consider the total number of points earned by each team across all games. We can calculate the total points for each team by adding up the points earned in each game.

For the Saints:

Total points = 21+12+3+3+10+10+14+3+12+28+40+10+17+20+7 = 200

For the Cowboys:

Total points = 10+3+8+6+24+12+21+3+10+28+28+7+7+13+3 = 183

Therefore, the Saints earned a total of 200 points, while the Cowboys earned a total of 183 points. Therefore, the Saints had the better overall record for the season.

To compare the central tendency of the points earned by each team, we can use either the mean or the median. However, in this case, the median is a better measure of center because it is less sensitive to extreme values than the mean.

Calculating the median for each team:

For the Saints:

Arrange the points earned in ascending order: 3 3 7 10 10 12 12 14 17 20 21 28 40

The median value is the middle value, which is 12.

For the Cowboys:

Arrange the points earned in ascending order: 3 3 6 7 8 10 10 12 13 21 24 28

The median value is the middle value, which is 10.

Therefore, the Cowboys have a median value of 10 points, while the Saints have a median value of 12 points. However, as we already determined, the Saints had a better overall record for the season based on the total points earned.

Step-by-step explanation: Trapezoids only have one pair of parallel sides.

She should multiply the prices on the tags by 0.9 to find the price she would have to pay, before tax, after the 10% discount.

To find the price Naomi would have to pay for her new sneakers after the 10% discount, she needs to multiply the original price on the tag by a factor that reflects the discount.

Since the discount is 10%, the factor by which she should multiply the original price is 1 minus 10% or 0.9. This is because the final price is equal to the original price minus the discount, which is 10% of the original price, or 0.1 times the original price.

So, if the price on the tag is $100, the price Naomi would have to pay, before tax, after the 10% discount would be:

$100 * 0.9 = $90

This means that she would save $10, which is 10% of the original price.

In general, if the original price on the tag is P, the price Naomi would have to pay, before tax, after the 10% discount would be:

P * 0.9 = 0.9P

[tex]\mu[/tex] is the mean in the given interval.

There is a 17.18% probability that a randomly selected region had exactly two hits.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

[tex]P(X=x)=\dfrac{e^{-\mu}\times\mu^x}{(x)!}[/tex]

In which

x is the number of successes

e = 2.71828 is the Euler number

[tex]\mu[/tex] is the mean in the given interval.

In this problem we have that:

A total of 525 bombs hit the combined area of 561 regions. So the mean hits per region is:

[tex]P=\dfrac{525}{561}=0.9358[/tex]

Assume that we want to find the probability that a randomly selected region had exactly two hits.

This is P(X = 2).

[tex]P(X=x)=\dfrac{e^{-\mu}\times\mu^x}{(x)!}[/tex]

[tex]P(X=2)=\dfrac{e^{-0.9358}\times(0.9358)^2}{(2)!}=0.1718[/tex]

The reasons behind GDP is an imperfect measure of economic well being are value of goods and services , economic activity, distributional issues, and depletion of natural resources .

GDP (Gross Domestic Product) is an imperfect measure of economic well-being for several reasons.

First,

GDP only measures the monetary value of goods and services produced within a country's borders.

It does not take into account non-market activities such as household work or volunteer work,

This can be significant contributors to well-being but are not included in GDP calculations.

Second,

GDP does not distinguish between desirable and undesirable economic activity.

For example, expenditures on environmental cleanup or healthcare are counted in GDP

Just as much as expenditures on cigarettes or military weapons.

Even though the former are beneficial for society, while the latter are not.

Third,

GDP does not measure distributional issues such as inequality, poverty, or social welfare.

Even if GDP were to increase,

It does not necessarily mean that all citizens have benefited equally from the economic growth.

Fourth,

GDP does not account for the depletion of natural resources or damage to the environment.

While economic growth may be achieved through unsustainable or environmentally destructive practices.

These costs are not reflected in GDP calculations.

Finally,

GDP does not capture the value of intangible factors such as social cohesion, quality of life, or happiness.

If GDP were to include non-market activities such as household work.

It would provide a more accurate measure of overall economic activity.

1. The probability a randomly selected pregnancy is more than 265 days in length The length of pregnancy follows a normal distribution with mean, μ = 268 days and standard deviation, σ = 15 days.The probability of pregnancy more than 265 days is:

P(X > 265)P(Z > (265 - 268) / 15)P(Z > -0.2) = 0.5793

2. The length of pregnancy that separates the shortest and longest 10% from the rest The length of pregnancy follows a normal distribution with mean, μ = 268 days and standard deviation, σ = 15 days.We need to find the length of pregnancy that separates the shortest and longest 10% from the rest.The length of pregnancy that separates the lowest 10% from the rest is the first decile.

The first decile is given by:

x1 = μ - 1.28σ x 1 = 268 - 1.28 (15) x 1 = 247.4 days

The length of pregnancy that separates the longest 10% from the rest is the ninth decile.The ninth decile is given by:

x9 = μ + 1.28σ x 9 = 268 + 1.28 (15) x 9 = 288.6 days

Yes, it would be unusual to select a pregnancy that lasts longer than 290 days. We can see from the calculation below:

P(X > 290)P(Z > (290 - 268) / 15)P(Z > 1.47) = 0.0708

The probability of pregnancy that lasts longer than 290 days is 0.0708.The probability of pregnancy that lasts less than or equal to 290 days is:

P(X ≤ 290) = 1 - P(X > 290) = 1 - 0.0708 = 0.9292

We know that if the probability of any event is less than 0.05 or 5%, it is considered unusual. As the probability of pregnancy that lasts longer than 290 days is only 0.0708, which is less than 0.05 or 5%, it is considered unusual.

The dimensions of the can that use the least amount of material are a radius of approximately 4.38 cm and a height of approximately 3.11 cm.

To design a can that uses the least amount of material, we want to minimize its surface area. Since the can is shaped like a right circular cylinder, its surface area is given by:

A = 2πr² + 2πrh

where r is the radius of the base of the cylinder and h is its height.

We also know that the volume of the can is given by:

V = πr²h

We can use these equations to express h in terms of r, and then substitute this expression for h into the equation for surface area. Then we can differentiate the resulting equation with respect to r, set it equal to zero, and solve for r to find the value of r that minimizes surface area.

First, we solve for h in terms of r by rearranging the equation for volume:

h = V/(πr²)

Substituting this expression for h into the equation for surface area, we get:

A = 2πr² + 2πr(V/(πr²))

A = 2πr² + 2V/r

To minimize A, we differentiate with respect to r:

dA/dr = 4πr - 2V/r²

Setting this expression equal to zero and solving for r, we get:

4πr = 2V/r²

r³ = V/(2π)

Substituting the given value for V, we get:

r³ = 432/2π

r ≈ 4.38 cm

Now we can use the expression for h in terms of r to find the corresponding height:

h = V/(πr²) ≈ 3.11 cm

Therefore, the dimensions of the can that use the least amount of material are a radius of approximately 4.38 cm and a height of approximately 3.11 cm.
