There are 5 erasers to accompany the 20 pencils based on the given ratio.

If the ratio of pencils to erasers is 4:1, and there are 20 pencils, we can determine the number of erasers by setting up a proportion.

The proportion can be written as:

pencils/erasers = 4/1

Given that there are 20 pencils, we can substitute this value into the proportion:

20/erasers = 4/1

To solve for erasers, we can cross-multiply:

\(20*1=4*erasers\)

\(20 = 4*eraser\)

Since there is only 1 unit assigned to erasers, we multiply the unit value (5) by the number of eraser units (1) to find the total number of erasers, which is 5.

Dividing both sides by 4:

20/4 = erasers

5 = erasers

Therefore, there are 5 erasers.

After 12 years, the population will be approximately 641,000 people.

To calculate the population after 12 years, we can use the formula for compound interest:

A = P * (1 + r)^n

Where:

A = Final population after n years

P = Initial population (390,000 people)

r = Annual growth rate (4.25% or 0.0425)

n = Number of years (12 years)

Plugging in the values:

A = 390,000 * (1 + 0.0425)^12

Calculating the exponent:

A = 390,000 * (1.0425)^12

Using a calculator or software, we can evaluate this expression:

A ≈ 390,000 * 1.64623657

A ≈ 641,000

Therefore, after 12 years, the population will be approximately 641,000 people.

The radius of the hemisphere is 9.5 inches.

The diameter of the hemisphere is 19 inches.

The surface area of the hemisphere is 850.2 inches²

circumference of a circle = 2πr

where

Therefore,

19π = 2πr

2r = 19

r = 19 / 2

r = 9.5 inches

diameter = 9.5 × 2 = 19 inches

Therefore,

surface area of an hemisphere = 3πr²

surface area of an hemisphere = 3 × 3.14 × 9.5²

surface area of an hemisphere = 850.155 inches²

surface area of an hemisphere = 850.2 inches²

What is the average time it took the car to travel 0.25 meters?

What is the average time it took the car to travel 0.50 meters?

I hope is work you!!

(1) The first velocity of the car with two washers at the 0.25 meter mark is 0.125 m/s.

(2) The second velocity of the car with two washers at the 0.5 meter mark is 0.25 m/s.

Velocity is the rate of change of displacement with time. The velocity of the  cars depends on displacement and time of motion.

The first velocity is calculated as follows;

v1 = 0.25 m / t1

let t₁ = 2 s

v₁ = 0.25/2

v₁ = 0.125 m/s

v2 = 0.25 m / (t2 – t1)

let t₂ = 3 s

v₂ = 0.25(3 - 2)

v₂ = 0.25 m/s

By completing the square, the equation in standard form is (x - 2)² + (y + 4)² = 4².

In Mathematics and Geometry, the standard form of the equation of a circle is modeled by this mathematical equation;

(x - h)² + (y - k)² = r²

Where:

From the information provided below, we have the following equation of a circle:

x² - 4x + y² + 8y = -4

x² - 4x + (-4/2)² + y² + 8y + (8/2)² = -4 + (-4/2)² + (8/2)²

x² - 4x + 4 + y² + 8y + 16 = -4 + 4 + 16

(x - 2)² + (y + 4)² = 16

(x - 2)² + (y + 4)² = 4²

Therefore, the center (h, k) is (2, -4) and the radius is equal to 4 units.

Answer:

4.8

Step-by-step explanation:

Answer:

4.8%

Step-by-step explanation:

to do this create a ratio and cross-multiply

\(\frac{60}{1240} = \frac{x}{100}\)

now that we have a our ratio, where x = the percent of poisonous trees, we can cross-multiply and solve to find its value

cross-multiplying leaves you with

\(1240x=6000\)

now solve for x, dividing both sides of your equation by 1240

once you've divided, you should be left with

\(4.8\)

since this number is already out of 100, it is equivalent to your percent, so slap a percent sign on the end and you're done!

The probability that a person prefers tea given that they prefer both coffee and tea is 0.9975 or 99.75%.

The probability that a person prefers tea given that they prefer both coffee and tea can be found using the conditional probability formula:

P(Tea|Coffee and Tea) = P(Coffee and Tea|Tea) * P(Tea) / P(Coffee and Tea)

where P(Coffee and Tea|Tea) is the probability that a person prefers both coffee and tea given that they prefer tea, P(Tea) is the probability that a person prefers tea, and P(Coffee and Tea) is the probability that a person prefers both coffee and tea.

From the survey results, we know that 40% of the people prefer both coffee and tea, which means that P(Coffee and Tea) = 0.4. Also, 35% of the people prefer tea, which means that P(Tea) = 0.35.

To find P(Coffee and Tea|Tea), we can use the fact that everyone who prefers both coffee and tea also prefers tea, so:

P(Coffee and Tea|Tea) = P(both Coffee and Tea)/P(Tea) = 0.4/0.35 = 1.14

Now, we can substitute these values into the conditional probability formula:

P(Tea|Coffee and Tea) = 1.14 * 0.35 / 0.4 = 0.9975

Therefore, the probability that a person prefers tea given that they prefer both coffee and tea is 0.9975 or 99.75%.

In other words, almost all people who prefer both coffee and tea also prefer tea.

Sajid covers a distance of 11km from the masjid to home and again a distance of 11km from home to the masjid. So, the total distance becomes 22km.

To calculate the total distance Saafi covers every day from his home to the masjid and back, we need to consider the round trip distance for each prayer. Since Saafi offers all 5 prayers regularly, he would make 5 round trips between his home and the masjid daily.

Round trip distance for each prayer = 2 * 2.2 = 4.4km

Total distance covered in a day = 5 * 4.4 = 22km

Therefore, Saafi covers approximately 22 km every day going from his home to the masjid and back.

To check the reasonableness of the calculated distance, let's assume Saafi walks at a speed of 4km/hr, then he would take 5.5 hrs to cover the distance. This suggests the need for additional information as this distance and time taken might be more for daily routine.

The conclusion that is correct in a two-tailed test at α = .05 is There appears to be no difference in the mean occupancy rates.

From the given values:

Thus, the P-value = 0.1791

Interpret results. Since the P-value (0.1791) is greater than the significance level (0.05), we failed to reject the null hypothesis.

From the above test, we do not have sufficient evidence in favor of the claim that there is a difference in the mean occupancy rates.

one solution (2.333, 9.6666)

Step-by-step explanation:

The ys have to be equal for there to be 1 solution. Let's see if they are. Equate the ys. - -2x becomes 2x

5x +-2 = 2x + 5                   Write the left with 1 sign

5x - 2 = 2x + 5                    Subtract 2x from both sides

2x          2x

3x - 2 = 5                            Add 2 to both sides

     2     2

3x = 7                                  Divide by 3

x = 7/3

x = 2 1/3

y = 5x - 2

y = 5(2 1/3) - 2

y = 11 2/3 - 2

y = 9 2/3

For a distribution that is symmetric, the left whisker is equal in length to the right whisker.

In a symmetric distribution, the left and right whiskers are of the same length. Symmetry implies that the distribution is balanced around its central point, which is usually the mean or median.

Consequently, the left side of the distribution mirrors the right side resulting in whiskers that have equal lengths. This balance ensures that the distribution is equally spread on both sides allowing for a clear representation of the spread and variability of the data.

By using simple algebra, we can find the number of pieces that will be played by Perry in one week,

So, we can write, The learing speed,

Number of piano pieces learnt = Weeks

19 pieces = 9 weeks

Learning speed = 19/9 Pieces per week

So, the number of pieces learnt in 12 weeks is,

Number of pieces learnt = 19/9 x 12
