Please help im on a timerrr

Step-by-step explanation:

7). Ratio of the students who name hockey as their favorite sport to hose who name basketball.

Ratio =

         =

         = 1 : 5

Option W is the answer.

8). Ratio of the students whose favorite sport is either baseball or soccer to the total students,

Ratio =

         =

         =

         = 11 : 19

Option O is the answer.

9). Ratio of the students who prefer soccer, basketball, baseball or hockey to those who preferred another sport,

Students who prefer soccer, basketball, baseball or hockey = 8 + 5 + 3 + 1 = 17

Students who prefer another sport = 2

Ratio = 17 : 2

Option K is the answer.

10). Ratio of total number of students to the students who preferred a sport with round ball,

Ratio =

         = 2 : 17

Option P is the answer.

the answer is 175.4379

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
