The square root of 2 is 1.4142 but eoindee it is just 1.4
Answer: A. Contractor A. The probability that both conditions are met is 0.93
Step-by-step explanation:
Probability of two independent events happening can be found by multiplying them.
Probability of A doing the job on time and on budget:
= Probability that job is done on time * Probability it is done on budget
= 0.97 * 0.96
= 0.93
Probability of B doing the job on time and on budget:
= 0.93 * 0.98
= 0.91
<em>Contractor A has the better probability at 0.93 so should be chosen. </em>
I cant see full picture....
We shall use the formula for distance traveled:
s = ut + (1/2)at^2
where
u = initial velocity
t = time
a = acceleration.
Because
u = 0 (car starts from rest),
t = 10 s (travel tme),
a = 2 m/s^2 (acceleration), m
the di mstance traveled is
s = (1/2)*(2 m/s^2)*(10 s)^2 = (1/2)*2*100 = 100
Answer: 100 m
Because ΔCDF is similar to ΔBDE, the corresponding sides are proportional
CD:BD=FD:ED
(3.63+5.19):5.19=(x+4.45):4.45
5.19(x+4.45)=(3.63+5.19)*4.45
5.19x+5.19*4.45=3.63*4.45+5.19*4.45
5.19x=3.63*4.45=16.1535
x≈3.11
you can also do DB:BC=DE:EF. You'll get the same result.
