Step-by-step explanation:
x = 0.8 + 0.2y
Answer:
1/2, 0.55, 5/7 is your answer
Step-by-step explanation:
Change each into decimal
1/2 = 0.50
0.55 = 0.55
5/7 = ~0.71
0.50 < 0.55 < 0.71

Answer:
The probability is:
Step-by-step explanation:
Keep in mind that the probability of getting a head is always the same for each
Therefore the probability of not having a head is:
So if we throw the coin 4 times the probability P of not getting any head is:
Answer:
There is a decrease of 0.75 sales per day
Step-by-step explanation:
Given:-
- The price of item = p
- The number of sales = x
- The relationship between "p" and "x" is given below:
4p+4x+2px=56
Find the rate at which x is changing when x=2, p=6, and dp/dt=1.5 The rate at which x is changing is [ ] sales per day
Take the time derivative (d/dt) of the entire given expression and apply chain rule on d/dt ( 2px ). Since both "p" and "x" are only functions of time "t":
d/dt
4p+4x+2px=56
4*dp/dt + 4*dx/dt + 2*(x*dp/dt + p*dx/dt)=0
Use the given values x=2, p=6, and dp/dt=1.5 to determine dx/dt
4*1.5 + 4*dx/dt + 2*(2*1.5+6*dx/dt)=0
6+4dx/dt + 2*(3+6dx/dt)=0
6+4dx/dt + 6+12dx/dt=0
12+16dx/dt=0
12=-16dx/dt
dx/dt= 12/-16
= -0.75
Answer:
b= 2 is the solution for the given equation.
Step-by-step explanation:
Here, the given expression is:
Simplifying Left side, we get
= 
Also, by ALGEBARIC IDENTITY:
So, 
So, LHS becomes 
Compare both Left side, Right side we get
= 
or, 7(b-3) + 5(b+3) = 10b -2
⇒ 7b - 21 + 5b + 15 = 10b -2
or, 12b - 10b = 6-2
or, 2b = 4 ⇒ b = 4/2 = 2
⇒ b= 2 is the solution for the given equation.
