Answer:
1 ft3= 0,028 m3
Step-by-step explanation:
We know that a 1 ft= 0,305 m,
if we cubed the above equation we have the following
1 ft3= (0,305)^3 m3
1 ft3= 0,028 m3
Answer:
(x-8) (x+2)
Step-by-step explanation:
x^2 – 6x – 16
Factor
What 2 numbers multiply to -16 and add to -6
-8 *2 = -18
-8+2 = -6
(x-8) (x+2)
Answer:
is 18
Step-by-step explanation:
simple you just subtract 27 for the original number
Answer:
a) 135 minutes
b) 15
c) 0.5
d) 0.3707
Step-by-step explanation:
A) What is the distribution's mean
mean(m) = (120 + 150)/2 = 270/2 = 135 minutes
B) What is the distribution's standard deviation
standard deviation(s) 
s = 15
C) What is the probability that a flight is less than 135 minutes
firstly calculate z score
z score = (x - m)/s = (135 - 135)/15 = 0
P(x<135) = z(0) = 0.5
D) What is the probability that a flight is more than 140 minutes?
z score = (x - m)/s = (140 - 135)/15 = 0.33
P(x>140) = 1 - P(x<140) = 1 - 0.6293 = 0.3707
Answer:
A
Step-by-step explanation:
We can see there are 2 parts of this function: one line for x<1 (because there is a circle for x=1, meaning it disincludes it) and one line for x >= 1 (because there is a filled circle for x=1, meaning it includes it). Therefore, we can disregard choice B (because it has x <= 1 and x > 1 instead of x<1 and x>= 1).
Notice that the part that x<1 passes through the origin, meaning the y-intercept is 0. In y= mx + b form of a line, b is the y-intercept, so b = 0 and we are looking for something in the form of y = mx for x < 1. Wee see that only in choice A that this is satisfied. Therefore, the answer is A.
I hope this helps! :)
