Answer:
Sheila have 6 bills
Step-by-step explanation:
Suppose Sheila has x '20' dollar bills, so the total cost of her bill = $20x
Suppose Tamsin has y '10' dollar bills, so the total cost of her bill = $10y
<h3>Equation 1</h3>
<em>Sheila has a total of $50 more than Tamsin</em>
<h2><em>10y + 50 = 20x</em></h2><h2 /><h3>
Equation 2</h3>
<em>Tamsin has 1 more bill than Sheila.</em>
<h2>y = x + 1 </h2><h2 />
<em>Now solve them by putting value of x in equation </em>
10( x + 1 ) + 50 = 20x
10x + 10 + 50 = 20x
60 = 20x - 10x
10x = 60
x = 60/10
x = 6
and
y = 7

Answer:
8.2
Step-by-step explanation:
3.2+2.3+2.7=8.2
Answer:
The probability mass function is
![F(x) = [ \left \ 8 } \atop {x}} \right. ] * p^x * q^{n - x }](https://tex.z-dn.net/?f=F%28x%29%20%3D%20%20%5B%20%5Cleft%20%5C%208%20%7D%20%5Catop%20%7Bx%7D%7D%20%5Cright.%20%5D%20%2A%20p%5Ex%20%20%2A%20%20q%5E%7Bn%20-%20x%20%7D)
Step-by-step explanation:
From the question we are told that
The maximum transmission time is 
Generally the number of times a packet is transmitted follows a binomial distribution given that the the results of successive transmissions are independent of one another and that the probability of any particular transmission being successful is p
Generally the probability mass function is mathematically represented as
Here x can take values x = 0 , 1 , 2 , 3 , ... , 7
Well there is to equations here that must be equal. X+20=4X Four times old means 4X+X=5X.
If you work to simply the problem you get something that looks like this:
X+20=5X
20=4X
x=20/4 or 5 y/o!
For this case we can make the following rule of three:
1 box -------------> 15 paperweights
x -------------------> 1269 paperweights
We clear the value of x.
We have then:
x = (1269/15) * (1)
x = 84.6
Rounding to the nearest whole:
x = 85
Answer:
There will be needed about:
x = 85 boxes
