Asurvey question revealed that at a particular college 87 percent of students worked at least sometime during their undergraduate career and 13 percent did not work at all. another question showed that 32 percent of the students worked throughout their undergraduate career. a pie chart is created that includes the category “students who worked sometime during their undergraduate career, but not throughout.” what would the central angle be for this category? a. 198 degrees b. 47 degrees c. 313 degrees d. 115 degrees give a straight answer! you! : )

A. 198 degrees

Step-by-step explanation:

Given : The proportion of students worked at least sometime during their undergraduate career = 87%= 0.87

The proportion of the students worked throughout their undergraduate career= 32%=0.32

Now, the  proportion of the students who worked sometime during their undergraduate career, but not throughout. = 0.87- 0.32= 0.55

For pie chart the central angle would be  :-

Hence, the central angle be for this category = 198 degrees

hi,

i'm 75% sure the answer is 1,1 to both lines.

have a great day

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
