Let's represent the number of weeks with the variable 'w':
130 + 25w = 600
We subtract both sides by 130:
25w = 470
w = 18.8
We round up:
It will take her 19 weeks.
Answer:
Step-by-step explanation:84% of a contractor’s jobs involves electrical work. 75% of a contractor’s jobs involve plumbing work. Of the jobs that involve plumbing, 90% of the jobs also involves electrical work. Let E = jobs involving electrical work L = jobs involving plumbing work Suppose one of the contractor’s jobs is randomly selected. Using the sixth Excel worksheet, a) Find P(E). 0.84 b) Find P(L). 0.75 c) In words, what does E | L mean? d) Find P(E | L). e) Find P(E and L). f) Are E and L independent events? Why or why not? g) Find P(E or L). h) Are E and L mutually exclusive? Why or why not
X/2 = 8
▶ ️2 = 8 × X. (transposing X to RHS )
▶️ 2 = 8X
▶ ️X = 8/2. (transposing 2 to RHS )
▶️ X = 4
hence the value of X is 4.
Answer:
m = 3
Step-by-step explanation:
Find the slope of the line connecting (-2,-3) and (-4,-9). (Note: you must use those parentheses.)
As we go from x= -4 to x = -2, an increase of 2, y increases by 6 from -9 to -3. The slope of this line is m = rise / run = 6/2 = 3.
You basically just take 3^2 and 2^2 to get 9/4
9/4 is the answer
