To plot 2 on the number line, we first need to locate the point for 1 and 10/4, and then we can find the midpoint between them.

We know that 1 is located to the left of 10/4, because 10/4 is equal to 2.5, which is greater than 2. So we can plot 1 to the left of the midpoint of the segment between 2 and 3.

To find the midpoint of the segment between 2 and 3, we can use the relationship between 1 and 10/4. We know that 10/4 is equal to 2.5, which is halfway between 2 and 3. So if we take the average of 1 and 2.5, we get:

(1 + 2.5) / 2 = 1.75

So 1.75 is the midpoint of the segment between 2 and 3. We can plot this point on the number line and label it as 10/4.

Finally, we can find the point halfway between 1.75 and 2, which is:

(1.75 + 2) / 2 = 1.875

Thus, 1.875 is the point halfway between 1 and 2. We can plot this point on the number line and label it as 2.

My scores were near the median for my team and my MAD was low.

The speed of the plane in still air is 400 miles per hour and the speed of the wind is 100 miles per hour.

What is speed?

Speed is a measure of how quickly something moves or the distance covered per unit of time.

Let's assume that the speed of the plane in still air is denoted by "p" (in miles per hour) and the speed of the wind is denoted by "w" (in miles per hour).

When the plane flew into the wind, it was flying against the wind resistance which reduced its ground speed. Let's assume that the wind was blowing with a speed of "w" (in miles per hour) during the flight. Then the speed of the plane relative to the ground (i.e. ground speed) would be:

p - w

Similarly, when the plane was flying with the wind on its way back, the ground speed would be:

p + w

Now, we can use the given information to set up two equations:

Distance = Speed x Time

For the first part of the trip (against the wind), the equation becomes:

1500 = (p - w) x 5

Simplifying this equation, we get:

p - w = 300 (Equation 1)

For the second part of the trip (with the wind), the equation becomes:

1500 = (p + w) x 3

Simplifying this equation, we get:

p + w = 500 (Equation 2)

Now we have two equations with two variables. We can solve for "p" and "w" by adding Equations 1 and 2:

2p = 800

p = 400

Substituting this value of "p" into Equation 2, we get:

400 + w = 500

w = 100

Therefore, the speed of the plane in still air is 400 miles per hour and the speed of the wind is 100 miles per hour.

Answer:

The sequence is increasing by 5 at each step. So, we can write:

a1 = 30

a2 = 30 + 5 = 35

a3 = 30 + 25 = 40

a4 = 30 + 35 = 45

a5 = 30 + 4*5 = 50

We notice that the nth term is given by:

an = 30 + (n-1)5

So, the explicit formula for the nth term is:

The answer of the given question based on hypothesis is ,(a)  the number of family is the sample size of 400 satisfies this requirement. (b) that the sample size should be sufficiently large.

In mathematics, a hypothesis is  statement or proposition that is assumed to be true for sake of argument or investigation, but has not been proven or demonstrated to be true. It is an educated guess or prediction that is based on previous observations or knowledge, and is used to guide further investigation or experimentation.

The other requirement that we need to meet to perform the hypothesis testing is that the sample size should be sufficiently large. A general rule of thumb is that the sample size should be at least 10 times larger than the number of successes and 10 times larger than the number of failures.

In this case, since we have 228 successes (families who want a condominium) and 172 failures (families who do not want a condominium), the sample size of 400 satisfies this requirement.

Answer: The estimated mean mathematics test score for the students is 685.7.

Step-by-step explanation: To estimate the mean mathematics test score, we can use the midpoint of each data class and the formula for calculating the weighted mean:

Midpoint of 550-599 class = (550 + 599) / 2 = 574.5

Midpoint of 600-649 class = (600 + 649) / 2 = 624.5

Midpoint of 650-699 class = (650 + 699) / 2 = 674.5

Midpoint of 700-749 class = (700 + 749) / 2 = 724.5

Midpoint of 750-799 class = (750 + 799) / 2 = 774.5

Weighted mean = (frequency of 550-599 class * midpoint of 550-599 class + frequency of 600-649 class * midpoint of 600-649 class + frequency of 650-699 class * midpoint of 650-699 class + frequency of 700-749 class * midpoint of 700-749 class + frequency of 750-799 class * midpoint of 750-799 class) / (total frequency)

Weighted mean = (6 * 574.5 + 10 * 624.5 + 15 * 674.5 + 12 * 724.5 + 8 * 774.5) / (6 + 10 + 15 + 12 + 8)

Weighted mean = 685.7 (rounded to one decimal place)

The point (10,30) is a solution to the equation 27x+15y=645

The point (10,30) means 10 adult tickets and 30 children tickets that cost $545 total.

In market 1, the quantity demanded will increase by 2.5% while in market 2, the quantity demanded will increase by 25%.

% Change in Quantity Demanded (Market 1) = (-) 0.25 * (-10%) = 2.5%

% Change in Quantity Demanded (Market 2) = (-) 2.5 * (-10%) = 25%

The negative sign for price elasticity of demand means that demand is inversely related to price.

For market 1:

Price = GH¢ 2

Quantity demanded = Q1

Change in price = -10% x GH¢ 2 = -GH¢ 0.20

Change in quantity demanded = 2.5% x Q1

Change in revenue = GH¢ 2.00 x 2.5% x Q1 = GH¢ 0.05 Q1

Marginal revenue = Change in revenue / Change in quantity demanded

Marginal revenue = (GH¢ 0.05 Q1) / (2.5% x Q1)

Marginal revenue = GH¢ 2.00

For market 2:

Price = GH¢ 1.50

Quantity demanded = Q2

Change in price = -10% x GH¢ 1.50 = -GH¢ 0.15

Change in quantity demanded = 25% x Q2

Change in revenue = GH¢ 1.50 x 25% x Q2 = GH¢ 0.375 Q2

Marginal revenue = Change in revenue / Change in quantity demanded

Marginal revenue = (GH¢ 0.375 Q2) / (25% x Q2)

Marginal revenue = GH¢ 1.50

The total revenue over the project life of 3 years is $10,500, the total costs over the project life of 3 years is 111,750 birr and Net benefit of the project is  $4,107

The annual value of exports is $3,500.

Therefore, the total revenue over the project life of 3 years is 3 × $3,500 = $10,500.

The cost of investment has foreign components of $1,200, which is equivalent to 21,000 birr (1,200 × 17.5).

The non traded component of the cost of investment is 7,500 birr.

The total cost of investment is therefore 21,000 + 7,500 = 28,500 birr.

The annual cost of traded inputs is $900, which is equivalent to 15,750 birr (900 × 17.5).

The total cost of traded inputs over the project life of 3 years is 3 × 15,750 = 47,250 birr.

The annual cost of non traded inputs is 12,000 birr.

The total cost of non traded inputs over the project life of 3 years is 3 × 12,000 = 36,000 birr.

Therefore, the total costs over the project life of 3 years is 28,500 + 47,250 + 36,000 = 111,750 birr.

Net benefit = Total revenue - Total costs

using 12 mm marbles would be more cost-effective, with a total cost of $360 compared to $810 for 9 mm marbles.

How to solve?

To calculate the number of marbles needed per vase, we first need to calculate the volume of each vase. The volume of a cylinder can be calculated using the formula V = πr²2h, where r is the radius and h is the height.

V = π(6 cm)²2(28 cm) / 2 = 3,758.76 cm²3

Since Janine intends to fill each vase halfway, the volume of water needed per vase would be:

V_water = 3,758.76 cm²3 / 2 = 1,879.38 cm²3

To calculate the volume of marbles needed per vase, we can subtract the volume of water from the total volume of the vase:

V_marbles = 3,758.76 cm²3 - 1,879.38 cm²3 = 1,879.38 cm²3

We can now calculate the number of marbles needed per vase based on the size of the marbles:

For 9 mm marbles:

The radius is 0.9 cm (9 mm / 10)

The volume of one marble can be calculated using the formula V = (4/3)πr²3

V_marble = (4/3)π(0.9 cm)²3 ≈ 2.138 cm²3

Number of marbles needed = V_marbles / V_marble = 879.38 cm^3 / 2.138 cm²3 ≈ 826 marbles

Total cost = 30 tables × $3/bag × 9 bags = $810

For 12 mm marbles:

The radius is 1.2 cm (12 mm / 10)

The volume of one marble can be calculated using the formula V = (4/3)πr²3

V_marble = (4/3)π(1.2 cm)²3 ≈ 7.238 cm²3

Number of marbles needed = V_marbles / V_marble = 1,879.38 cm²3 / 7.238 cm²3 ≈ 260 marbles

Total cost = 30 tables × $4/bag × 3 bags = $360

Therefore, using 12 mm marbles would be more cost-effective, with a total cost of $360 compared to $810 for 9 mm marbles.
