The profit in 1973 is 5.56 which is estimated by the given linear model.

The regression equation is used to predict or estimate the value of the response (or dependant) variables based on an understanding of the explanatory (or predictor) variables.

Let Y represent the profit (or loss) for a certain company X years after 1970. Based on the data shown, a statistician calculates a linear model

Y = -0.80X + 7.96 ....(i)

Using the above model to estimate the profit in 1973

Substitute the value of X = 3 in the equation (i),

Y = -0.80(3) + 7.96

Y = -2.4 + 7.96

Y = 5.56

This is the profit in 1973.

The coordinate of a point whose distance from both P and Q is exactly 13 is; (15, 24)

Pythagorean theorem:

According to the Pythagorean theorem, in a right triangle (90 degrees), the square of the hypotenuse equals the sum of the squares of the other two sides. Consider the following triangle ABC where BC2 = AB2 + AC2. where AB is the base, AC is the height (height), and BC is the hypotenuse.

The coordinate of a point whose distance from both P and Q is exactly 13 is; (15, 24)

The distance between points, P and Q can be evaluated by the Pythagoras theorem as follows;

Distance, PQ = √(20-10)² + (36-12)²

PQ = √(100+576)

PQ = √676

PQ = 26.

Therefore, a point whose distance from both P and Q is exactly 13 is the midpoint of PQ.

Therefore,

x = (20 + 10)/2

As per the permutation method, there are 215,160 different ways are available for making the letters with vowel as the starting letter and s as the ending letter.

The term permutation in math is defined as  a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters

Here we need to find the number of combination for the word that start with a vowel and end with an s.

As we all know that there are 26 letters in alphabets.

so that would be all four letter words - four letter words with no vowel.

Then it can be calculated as the total number of four letter words

=> 26P4 or 26C4*4!

Then the number of four letter words without a vowel is calculated as

=> 21P4

Therefore, it can be written as,

=> 26P4 - 21P4

Then the resulting word count is calculated as,

=> (26 x 25 x 24 x 23) - (21 x 20 x 19 x 18)

Answer:

a. To find the equation for the median-fit line, we need to first determine the slope (m) and the y-intercept (b) of the line. We can use the following formulas to calculate these values:

m = (nΣxy - ΣxΣy) / (nΣx^2 - (Σx)^2)

b = median y - m(median x)

Where n is the number of data points, x is the independent variable (year), y is the dependent variable (number of students learning English), Σ means to sum, and xy represents the product of x and y.

For this dataset, we have 5 data points, so n = 5.

x = 2003, 2004, 2005, 2006, 2007

y = 1.600, 1.599, 1.592, 1.570, 1.560

Σx = 10,015

Σy = 7,966

Σxy = 31,948

Σx^2 = 40,307

m = (531948 - 100157966)/(5*40307 - 10015^2) = -0.007

median x = 2005

median y = 1592

b = 1592 - -0.007 * 2005 = 1597.014

The equation for the median-fit line is:

y = -0.007x + 1597.014

b. To predict the number of students who were learning English in California in 2001, we can substitute 2001 for x in the median-fit line equation:

y = -0.007(2001) + 1597.014 = 1600.087

c. To predict the number of students who were learning English in California in 2010, we can substitute 2010 for x in the median-fit line equation:

Answer:

i. To calculate the total expenses in Kenya shillings incurred by Wekhomba, we need to first convert the cost of the laptop in Uganda shillings to Kenya shillings using the exchange rate of 1 US dollar = Ush 1016. The cost of the laptop in Kenya shillings is (1,050,000/1016) = 1,032,474.40

We then need to add the transportation cost of 60 US dollars which is (60 * 1016) = 61,596 Kenya shillings.

Taxes in Kenya amounting to 55% of the cost in Uganda is (1,050,000 * 55/100) = 577,500 Uganda shillings which is (577,500/1016) = 567,715.20 in Kenya shillings.

The total expenses in Kenya shillings incurred by Wekhomba is 1,032,474.40 + 61,596 + 567,715.20 = 1,661,785.60

ii. To find the expenditure on transportation and taxes as a percentage of the total expenditure, we need to divide the sum of transportation costs and taxes by the total expenses and multiply by 100.

Expenditure on transportation and taxes is 61,596 + 567,715.20 = 629,311.20.

Expenditure on transportation and taxes as a percentage of the total expenditure = (629,311.20/1,661,785.60) * 100 = 37.9%

iii. To find the total value of the laptop in Tanzanian shillings, we first need to convert Kenya shillings to Tanzanian shillings using the exchange rate of 1Ksh = Ush 24.83 and Tsh 1 = Ksh 0.0714,

1,661,785.60 Kenya shillings is (1,661,785.60/24.83) = 668,817.51 Uganda shillings which is (668,817.51 / 0.0714) = 93,622,817.16 Tanzanian shillings

iv. To find the overall increase in value of the laptop as a percentage of the buying price, we need to divide the increase in value (total value in Tanzanian shillings - buying price) by the buying price and multiply by 100.

Overall increase in value = 93,622,817.16 - 1,050,000 = 92,572,817.16

The overall increase in value as a percentage of the buying price = (92,572,817.16/1,050,000) * 100 = 88.1%

The probability that at least one person receives exactly one aces in their 52 cards is 4/52= 1/13

We define the following events:

A: person A receives exactly two aces in their five cards.

B: person B receives exactly two aces in their five cards.

C: person C receives exactly two aces in their five cards.

We need to calculate P(A∪B∪C). According to the principle of inclusion and exclusion:

P(A∪B∪C)= P(A)+P(B)+P(C)-P(A∩B)-P(A∩C)-P(B∩C)+P(A∩B∩C)

Total outcomes is equal to  because there 52 cards and we select 5 of them.

The probability of each event is given by:

P(A)=P(B)=P(C)===0.0399

where the possible outcomes are 2 aces and 3 of the other cards.

Then, the intersections of the events mean that one player gets 2 aces and the other gets 2 aces too.

P(A∩B)=P(B∩C)=P(A∩C)==0.0001

Finally,

P(A∩B∩C)=0 because it is not possible that the three events occur at the same time due to there are only 4 aces.

P(A∪B∪C)= 0.0399+0.0399+0.0399-0.0001-0.0001-0.0001+0

P(A∪B∪C)=0.1194

The total cost of the bridge will be (200/2) × 8 × 1000 + 50 × 10 + 500 = $90,000.

The formula for calculating the cost of a bridge is Cost = (Area of Bridge/2) × Unit Weight of Steel × Unit Price of Steel + Cost of Labor + Cost of Other Materials. By using this formula, we can determine the total cost of the bridge by considering the area of the bridge, the weight of the steel used, the price per unit of steel, the cost of labor, and the cost of other materials. For example, if the area of the bridge is 200m^2, the unit weight of steel is 8 tonnes/m^3, the unit price of steel is $1000/tonne, the cost of labor is $50 per hour, and the cost of other materials is $500, then the total cost of the bridge will be (200/2) × 8 × 1000 + 50 × 10 + 500 = $90,000.

The car consumes 3 gallons and 8.2 gallons of fuel respectively.

Milage:

Divide the distance traveled by the amount of gas used. For example, driving 100 miles with a full tank and 5 gallons of gas is 10mpg. When it comes to fuel economy, it's important to know how much your car is costing you each time we drive it.

According to the Question:

The gas mileage is the number of miles that can be covered by a car for a particular amount of fuel.

We are given that the gas mileage of the car is 30 miles per gallon, that means that the car consumes 1 gallon of fuel for each 30 miles covered.

The amount of fuel needed to cover the following distance is:

a) For 90 miles, let x represent the number of gallon of fuel. Hence:

Distance covered / amount of fuel = 30 miles per gallon

  90/x = 30

⇒ x = 90/30

⇒ x = 3 gallons

b) For 246 miles, let x represent the number of gallon of fuel. Hence:

Distance covered / amount of fuel = 30 miles per gallon

⇒ 246/x = 30

⇒ x = 246/30

⇒ x = 8.2 gallons

Therefore, the car consumes 3 gallons of fuel for 90 miles and 8.2 gallons for 246 miles.

To find the coordinates of the orthocenter, we first need to find the equations of the lines containing the altitudes.

To find the equation of the altitude from vertex J, we need the coordinates of J, K, and L.

Using the given coordinates, we have J(3,-2), K(5,6), and L(9,-2).

The equation of the line containing the altitude from J is:

-2 = (-2-6)/(3-5) (x-5) + 6

The equation of the line containing the altitude from K is:

6 = (-2-6)/(5-9) (x-9) - 2

The equation of the line containing the altitude from L is:

-2 = (6-(-2))/(5-3) (x-3) + 2
