TAREA Nº 11 ECUACIONES DE PRIMER GRADO CON UNA INCÓGNITA HALLAR EL CONJUNTO SOLUCIÓN DE LAS ECUACIONES

1) xx= 2

2) x + 1 = 0

3) 2x - 7 = 5x + 2

4) 5x - 2x + 1 = x - 11

5) x+ 2x - 2 = 3x - 2

6) 6x +7- 2x = - x -

I dont understand u

Step-by-step explanation:

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

answer: the answer is (b) amie should have multiplied

step-by-step explanation: given a sphere and a cylinder with same radius and height.

let, 'r' be the radius of the cylinder and sphere and 'h' be the height of the cylinder. according to the question,

r = h.

now, the volume of the sphere will be

and the volume of the cylinder will be

therefore, we have

thus, ammie should have multiplied the volume of the sphere
