Answer:
3
Step-by-step explanation:
Circumference = , where r is radius, and d is diameter
d=113/3.14=35.987, which is approximately 36
At 12 yards per hour, it will take 36/12=3 hours
Answer:
y = -2
Step-by-step explanation:
The line x = -3 is a vertical one; the slope of a line perpendicular to x = -3 is zero (0). Recall that the slope of a vertical line is undefined and that of a line perpendicular to a vertical line is 0.
Then, to write the equation of the perpendicular line, we borrow the '-2' from (-9, -2) and write y = -2. This line does indeed pass through (-9, -2) and every other point whose y-component is -2.
Answer:
0.25
Step-by-step explanation:
40% of the students use mac computer
67% of the students are undergraduate
23% of the students are graduates and use mainly PC
Students that use PC computers = 100 -40 = 60%
Students that are graduates = 100 - 67 = 33%
Students that are graduates that use Mac = 33 - 23= 10%
Students that are undergraduate that use PC = 67 - 30 = 37%
Using conditional probability
Pr(B|A) = Pr(A and B) / Pr(A)
Pr(Graduate | mac) = Pr(graduate and mac) / Pr(mac)
= 10%/ 40%
= 1/4
= 0.25
Answer:
y=-2/3(x-5)-9
sorry for bad handwriting and forget - with slope
Answer:
Step-by-step explanation:
<u><em>The question is</em></u>
Solve for y
we have
Solve for y
That means ---> isolate the variable y
Divide by 3 both sides
Simplify right side
Rewrite
therefore
Your answer is correct
