Question 7
The equation of a straight line AB is

(a) Find the gradient of line AB.
(b) Find the y-intercept of line AB.
(c) A second line PQ is parallel to the line AB and passes through a point (2, -8).
Show that the second line PQ also passes through the point(-1,-5)
Bp's expansion plans had been reduced, and its capacity to compete with other large multinational oil companies like Exxon Mobil and ShellExplanation has become restricted.
BP's new cause is reimagining energy for people and our planet. The cause is underpinned by way of an industry-leading ambition – for BP to become a net zero organization by 2050 or faster, and to help the world get to net zero – and this ambition is supported by using 10 goals.
The strong development bp has made over the last few years has reinforced its confidence in the shipping of its earnings and returns goals for 2025. further, it's far now aiming to keep growing EBITDA through to 2030.
It's critical to show BP's graduate recruiters that you percentage BP's five middle values: safety, respect, excellence, one crew, and braveness.

Answer:
A) The use of both techniques ( i.e. questionnaire and Interview )
B) The sampling method should include an equal number of workers from each shift, this is to ensure that every shift's opinion is broadly covered.
Explanation:
A) The best approach in resolving this problem is the application of both questionnaires and interviews, this is because the questions will be covered in both the questionnaire and interview therefore a more detailed/accurate answer can be gotten by combining both processes
B) The sampling method should include an equal number of workers from each shift, this is to ensure that every shift's opinion is broadly covered.
Answer:
Freezer 2 is the better option because it has higher present worth.
Explanation:
Answer:
a. Carol's transfer price is $6 per meal if she only recovers the variable costs.
b. $13,5 per meal
c. $27000 or a loss of $1.5 per meal.
d. The cost of the cafeteria should be charged to the user departments so that the actual profit or loss from each department can be valued
Explanation:
a. Variable costs = $108000 for 18000 meals.
Variable cost per meal = 108000 / 18000 = $6
Carol's transfer price is $6 per meal if she only recovers the variable costs.
b. If carol were to recover the full cost then the transfer price = Total cost / no. of meals
= (108000 + 135000) / 18000 = $13,5 per meal
c. If the transfer price is the market price i.e $12, the loss from the cafeteria = Revenue from meals - Total cost
= (18000 x 12) - (108000 + 135000)
= $27000 or a loss of $1.5 per meal.
d. The cost of the cafeteria should be charged to the user departments so that the actual profit or loss from each department can be valued.
This information is useful to the hospital management in knowing the actual costs of the meals consumed in the various departments and how the cost cutting measures can be implemented based on the cost of the different departments.
