Answer:
18 miles driven in a week
Step-by-step explanation:
a unit rate is x/1, x being 18 miles and 1 being 1 week
Answer:
La edad actual de Beatriz es de:
30 años
Step-by-step explanation:
Planteamiento:
5e = 4b
(e+3) + (b+3) = 60
e = edad actual de José
b = edad actual de Beatriz
Desarrollo:
de la segunda ecuación del planteamiento:
e + b + 6 = 60
e + b = 60 - 6
e + b = 54
e = 54 - b
sustituyendo este último valor en la primer ecuación del planteamiento:
5(54-b) = 4b
5*54 + 5*-b = 4b
270 - 5b = 4b
270 = 4b + 5b
270 = 9b
b = 270/9
b = 30
e = 54 - b
e = 54 - 30
e = 24
Comprobación:
5e = 4b
5*24 = 4*30 = 120
Basically, the closer they fit to the imaginary line of best fit, the higher they are
the closer the dots are to the imaginary line, te higher the number
D looks the closest together so that is first
A is a little farther apart
C is farther
B is farthers
DACB is order
As written, it is interpreted to mean 14·22·350·x = 107800x.
_____
Often such an expression written here on Brainly is expected to be interpreted as an exponential expression: 
Answer:
For X, the parameter
is λX = 1/2 and for Y it is λY = 1. Using the formula sheet, Mean is
E[Z] = E[X] + 2E[Y ] = 4. Variance is V ar(Z) = V ar(X) + 4V ar(Y ) = 8.
