Is line 1 (1,5) (3,-2) and like 2 (-3,2) (4,0) perpendicular of parallel?
Lera25 [3.4K]
  • Slope Formula: \frac{y_2-y_1}{x_2-x_1}

So remember that <u>perpendicular lines have slopes that are negative reciprocals to each other</u> and <u>parallel lines have the same slope.</u> To find out if they are either parallel or perpendicular, plug the pair of points into the slope formula to find their slopes:

\textsf{Line 1}\\\\\frac{5-(-2)}{1-3}=-\frac{7}{2}\\\\\textsf{Line 2}\\\\\frac{0-2}{4-(-3)}=-\frac{2}{7}

Since these slopes aren't the same nor are they negative reciprocals to each other, <u>the lines are neither parallel nor perpendicular.</u>

Mary owns a coffee shop. She charges $4.50 for a cup of coffee, and it costs her $1.25 to make each cup of coffee plus a $75 a d
Elena L [17]

Answer:

Approximately 23 cups of coffee

Step-by-step explanation:

Break even = Fixed cost/Selling price - variable cost

Fixed cost = $75

Selling price = $4.50

Variable cost = $1.25

Break even = $75/$4.50 - $1.25

= 23.076923077

Approximately = 23

Therefore, Mary has to sell approximately 23 cups of coffee daily in order to break evem

A random sample of 100 college students is taken from the student body of a large university Assume that, in fact, a population
mixas84 [53]

Answer:

b) equals 20 hours.

Step-by-step explanation:

The sampling distribution of means refers to the distribution of all the possible sample means, with a certain sample size (in this case, n=100) extracted from the population.

The sampling distribution of the means is equal to the population mean. That does not mean that every sample will result in a mean equal to the population, but that the population of sample means will have an average of 20 hours.
