60mph-10mph=T would be the answer... I believe.
Answer:
<h2>101010101010101010 </h2>
Step-by-step explanation:
given the binary operation a⊕ b=a^3−b and c = 101010101010101010
To get the value of c⊕ (c ⊕ c), we will express the binary given as that in question as shown;
c⊕ (c ⊕ c) = c³-(c ⊕ c)
c⊕ (c ⊕ c) = c³-(c³-c)
On expansion;
c⊕ (c ⊕ c) = c³-c³+c
c⊕ (c ⊕ c) = c
since c = 101010101010101010
c⊕ (c ⊕ c) = 101010101010101010
So 4.75 times 42= 199.5 so take 240-199.5= 40.5 so he is correct
Answer:
The probability that a randomly chosen light bulb will last less than 900 hours is 0.1587.
Step-by-step explanation:
The life span of these light bulbs is normally distributed with a mean of 1000 hours and a standard deviation of 100 hours
Mean = 
Standard deviation =
We are supposed to find the probability that a randomly chosen light bulb will last less than 900 hours.i.e. P(x<900)
So, 
Z=-1
P(x<900)=P(z<-1)=0.1587
Hence the probability that a randomly chosen light bulb will last less than 900 hours is 0.1587.
This is the concept of graphs and volume of the solid figures, given that the triangle J,K,L was rotated along the x-axis, the resultant figure was cone with with radius of 5 units and a height of 4 units;
The volume of a cone is given by;
V=πr^2(h/3)
r=5 units
h=4 units
V=π*5^2*(4/3)
V=104.72 units^3
the answer is B]
