Answer:
the answer is 14 converting 1and 1/6 to improper fraction gives u 7/2 then dividing by 1/12 is 14
Answer:
It can be done using poisson distribution.
λ = 30 calls/hr = 1.5 calls/3min
Now P(X=x)=e−λ.λxx!
So P(X=0)=e−1.5
Step-by-step explanation:
Answer:
- 19. y = x + 1
- 20. y = -2/3x - 5
- 21. y = -1/2x + 7
- 22. y = 4x - 3
Step-by-step explanation:
19. Passing through (2, 3) and PARALLEL to y = x - 4
<u>Parallel lines have equal slopes:</u>
<u>Use given point to find b:</u>
<u>The line is:</u>
20. Passing through (-6, -1) and PARALLEL 2x + 3y = 3
<u>Rewrite in the slope-intercept form:</u>
- 2x + 3y = 3
- 3y = -2x + 3
- y = -2/3x + 1
<u>The line have same slope:</u>
- y = -2/3x + b
- -1 = -2/3(-6) + b
- -1 = 4 + b
- b = - 5
<u>The line is:</u>
21. Passing through (-2, 8) and PERPENDICULAR to y = 2x + 5
Perpendicular lines have negative-reciprocal slopes
<u>The line has the form:</u>
Find the y-intercept:
- 8 = -1/2*(-2) + b
- 8 = 1 + b
- b = 7
<u>The line is:</u>
22. Passing through (-2, -11) and PERPENDICULAR to x + 4y = 8
Perpendicular lines have negative-reciprocal slopes
<u>Rewrite in slope-intercept form:</u>
- x + 4y = 8
- 4y = -x + 8
- y = -1/4x + 2
<u>The line has the form:</u>
<u>Find y-intercept:</u>
- -11 = 4(-2) + b
- -11 = -8 + b
- b = -3
<u>The line is:</u>
Given two points, say points
A and
B, we can use the slope formula to find the slop of the line:
If
A has coordinates of
(w,c) and
B has coordinates of
(y,z), we can find the slope.
}{y-w} [/tex]
Now we can say that we can use the point slope form formula:
Now we can substitute
m for the slope, and use any points to plug in
and
.
Hope this helps! :^)
Answer:
7/8
Step-by-step explanation:
turn 1/4 denominator into 8 and by doing that, u multiply by 2.
whatever you do to the bottom, u do to the top. so 1/4= 2/8
5/8+2/8= 7/8
