Answer:

75

Step-by-step explanation:

Line up the numbers in order from smallest to largest

70 72 77 80 81

We have an unknown number

The median is 76

The median is the middle number

We know it has to be smaller than 77

Put it as the 3rd number since the median is 76

70 72    x  77     80 81

since there is an even number of points the median is the average of the middle numbers

x+ 77 divided by 2 = 76

x+77 = 76*2

x+77 = 152

x = 152 - 77

x =75

A veterinarian will prescribe an antibiotic to a dog based on its weight. The effective dosage of the antibiotic is given by d ≥
gregori [183]

Answer:

B) (35, 260)

Step-by-step explanation:

A veterinarian will prescribe an antibiotic to a dog based on its weight. The effective dosage of the antibiotic is given by d ≥ 1∕5w2, where d is dosage in milligrams and w is the dog's weight in pounds. Which of the following ordered pairs gives an effective dosage of antibiotics for a 35-pound dog?

A) (35, 240)

B) (35, 260)

C) (260, 35)

D) (240, 35)

Ordered pairs is composed of pairs, usually an x coordinate and a y coordinate. It refers to a location of a point on the coordinate. It matches numbers to functions or relations.

Given the relation between d is dosage in milligrams and w is the dog's weight in pounds as d ≥ 1∕5w²

For a 35 pound dog (i.e w = 35 pound). The dosage is given as:

d ≥ 1∕5(35)² ≥ 245 milligrams.

For an ordered pair (x, y), x is the independent variable (input) and y is the dependent variable (output).

The dog weight is the independent variable and the dosage is the dependent variable.

From the ordered pairs, the best option is (35, 260) because 260 ≥ 240

 = 3x + (-4y)
 = 3x-4y 
 So option A is the correct one.
