Slope-intercept form is simply y=mx +b
your equation is 3x -y = 7
rearranging that to y = mx +b makes it look like this:
- y = -3x +7
y =3x -7
making m =3 and b=-7, so your answer is C
Answer:
Step-by-step explanation:
Whenever you have exponents raised to another exponent, you multiply the exponents!
It is approximately a thousand times larger
Answer:
1/2 ; 1/3 ; 1/6
Step-by-step explanation:
Given :
Ben ~ exp(1)
Max ~ exp (2)
Yolanda ~ exp(3)
Ben :
X ~ exp(1)
Max:
Y ~ exp(2)
Yolanda :
Z ~ exp(3)
Probability that Yolanda is served first :
P(Z < (X, Y)) = Z /(x + y + z) = 3 /(1 + 2 + 3) = 3/6 = 1/2
Probability that Ben is served before Yolanda :
P(X < Z) = 1/ (1 + 2) = 1/3
Expected waiting time for first person served :
First person served = 1
Total = (1 + 2 + 3) = 6
Expected waiting time; E(x) :
E(x) : 1 / 6
Answer:
19. 5 feets
Step-by-step explanation:
Shadow of tree = 26 feets
Height of flower = 3 feets
Shadow of flower = 4 feets
Height of sun Innthe sky:
Shadow of flower / height of flower
= 4/3 = 1.333333
Height of tree:
Shadow of tree / height of sun
26 feets / 1.33333
= 19.5 feets
Hence, height of tree = 19.5 feets
