Answer:
1.5 bags
Step-by-step explanation:
Width = 1 yard = 3 feet
Length = 5 feet
Square feet(area) of the floor = 5ft × 3ft = 15sqft
1 bag = 10sqft
x bag = 15sqft
x bags = (15 × 1)/10 = 1.5 bags
Answer:
Recall that probability is given as; the number of required outcome over the number of total possible outcome.
The probability that a transmitter receives the signal being sent by itself is given as
.
when there are n transmitters, the probability will be given as 
Step-by-step explanation:
Probability simply the likelihood of an event occurring or not occurring.
Probability therefore is given as; the number of required outcome over number of possible outcome.
In the case of the first part above we have the number of required outcome to be at least one divided by the number of possible outcome which is 3.
while in the second part we have the number o possible outcome to be n.
Answer:
-221 base 3
Step-by-step explanation:
We are to calculate the value of the numbers in base 3. One of the ways to do that is to first convert each number to base 10. Do the arithmetic, then convert back to base 3.
121 base 3 +2122 base 3 - 1200 base 3 - 2111 base 3
Let's convert to base10
See attachment for details
From the workings,
121 base 3 + 2122 base 3 - 1200 base 3 - 2111 base 3 = -221 base 3
Answer:
C=0.46 s⁻¹
Step-by-step explanation:
The general equation for the damped harmonic system given as

Where
A= Amplitude

C=Damping constant
Lets take at time t= t₁, A= K
And at time t= t₁+3 s ,A= K/4

-----------1
-------------2
From equation 1 and 2



C=0.46 s⁻¹
