The linear equation y = 13x + 80 can be used to model the total cost y (in pounds) for x people attending the greyhound racing evening at Option A. (i) Explain why this equation holds.

Answers

Answer 1

Answer:

Justification of 'Cost of Match , based on attendants' linear equation

Step-by-step explanation:

Yes , this linear equation might hold right in denoting total cost 'y' for 'x' people attending racing event

Given equation  : y = 13x + 80

Cost 'y' is the variable dependent on explanatory variable ie no. of race attendants. So, y is on LHS, being determined by x on LHS.

80 is the autonomous constant intercept of equation, denoting fixed setup cost irrespective of no. of attendants. +13x denotes every additional attendant increases cost by 13 units (above the level of fixed cost), this is the positive slope of equation (as variables are directly related)

Answer:

  29 in²

Step-by-step explanation:

No need to be stumped. The dashed lines divide the figure into three recognizable forms, for which you have area formulas.

The area of a rectangle or parallelogram is given by the formula ...

  A = bh . . . . .  where b represents the base, and h represents the height.

__

The top part of the figure is a square. That is, it is a rectangle with its base equal to its height. In this figure, both are labeled 2 in.

  A = (2 in)(2 in) = 4 in² . . . . . . area of top square

The middle part of the figure is a parallelogram. Its base is the same as the base of the rectangle below it. Its height is labeled 3 in.

  A = (5 in)(3 in) = 15 in² . . . . . . area of middle parallelogram

The bottom part of the figure is a rectangle with a height of 2 in. Its base is the same length we used for the parallelogram: 5 in.

  A = (5 in)(2 in) = 10 in²

The area of the figure is the sum of the areas of its parts:

  figure area = 4 in² + 15 in² + 10 in² = 29 in²

The area of the figure is 29 in².

Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV. He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV. Is Johnny making a valid inference about this population? (5 points)

a
Yes, it is a valid inference because his classmates make up a random sample of the students in the school

b
Yes, it is a valid inference because he asked all 26 students in his science class

c
No, it is not a valid inference because he asked all 26 students in his science class instead of taking a sample from his math class

d
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
