Simplify this expression. Assume that w is nonzero. Use pencil and paper. Describe how the values of the expression vary with the values chosen for w.
Give examples.
8w^0
Answer:
[tex]8w^{0} = 8[/tex]
Step-by-step explanation:
[tex]8w^{0}[/tex] ------------(1)
Assume any non-zero value of w (w=2)
Put this value in (1)
[tex]8(2)^{0}[/tex]
zero power of any number is 1. Therefore
[tex]8(2)^{0} = 8[/tex]
Assume any other non-zero value of w (w=100)
Put this value in (1)
[tex]8(100)^{0}[/tex]
we know zero power of any number is 1. Therefore
[tex]8(100)^{0} = 8[/tex]
For any non zero value of w answer will always be 8. Expression can be written in simplified form as
[tex]8w^{0} = 8[/tex]
The probability of a tropical storm becomes a hurricane is 0.53. If the weather service predicts 6 more tropical storms, what is the probability that exactly 5 of them become hurricanes?
Answer:
0.1179
Step-by-step explanation:
Given that :
p = 0.53
n = 6 ; x = 5
P(x = 5)
According to the binomial probability formula :
P(x = r) = nCr * p^r * (1 - p)^(n - r)
P(x = 5) = 6C5 * 0.53^5 * (1 - 0.53)^(6 - 5)
P(x = 5) = 6C5 * 0.53^5 * 0.47^1
P(x = 5) = 6 * 0.53^5 * 0.47^1
P(x = 5) = 0.117931129026
= 0.1179

At a high school championship game 1200 tickets were sold. Student tickets cost $1.50 each and adult tickets cost $5.00 each. The total revenue collected for the game was $3200. How many of each ticket were sold for the game?
Answer:
Students= 800
Adults= 400
Step-by-step explanation:
Given data
number of tickets= 1200
let students be x
and adults be y
x+y= 1200--------------------1
'
The total revenue collected for the game was $3200
so
1.5x+5y=3200-------------2
Solve 1 and 2 for x and y
x= 1200-y
put this is 2
1.5( 1200-y)+5y=3200-------------2
1800-1.5y+5y= 3200
3.5y= 3200-1800
3.5y=1400
Divide both sides by 3.5
y= 1400/3.5
y=400
Put y= 400 in 1
x+400= 1200
x= 1200-400
x=800
5. It took 400 rails to create one mile of track. Each rail had ten (10) spikes. Each spike needed three (3) strikes from a hammer. A fast crew could lay four (4) rails in one minute. Crews averaged five (5) miles of track per day. If the distance from Rock Island, Illinois to Sacramento, California is approximately 1800 miles: How many rails were needed? How many spikes were needed? How many hammer strikes were heard each hour? How many days were needed to complete the track?

Dave has 85p ellie has £1.43 How much should ellie give to dave so that they both have the same amount of money
Answer:
29p
Step-by-step explanation:
Money available with Dave = 85p
Money available with Ellie = £1.43
To find:
How much money should Ellie given to Dave so that they both have the same amount of money?
Solution:
First of all, let us convert £ to p.
1 £ = 100p
1.43£ = 143p
Let number of 'p' that Ellie has to give to Dave so that they have equal amount of money = [tex]x[/tex] p
Money left with Ellie after giving [tex]x[/tex] p to Dave = (143 - [tex]x[/tex])p
Money with Dave after taking [tex]x[/tex] p from Ellie = (85 + [tex]x[/tex])p
As per question statement, money with both of them is same.
i.e.
[tex]143-x=85+x\\\Rightarrow 2x=143-85\\\Rightarrow 2x = 58\\\Rightarrow x = \bold{29p}[/tex]
Therefore, Ellie should give 29p to Dave so that they have same amount of money.
They both will have 1.14£ or 114p each.

This equation shows how the time required to ring up a customer is related to the number of items being purchased. t = 4p + 20 The variable p represents the number of items being purchased, and the variable t represents the time required to ring up the customer. If it takes 44 seconds to ring up a customer, how many items are being purchased?
Answer:
6 items are being purchased
Step-by-step explanation:
Given that variable p represents the number of items being purchased, and the variable t represents the time required to ring up the customer, If it takes 44 seconds to ring up a customer then the number of items being purchased may be computed by substituting the value of t into the given equation
t = 4p + 20.
Using t = 44
44 = 4p + 20
collect like terms or subtract 20 from both sides
44 - 20 = 4p
24 = 4p
Divide both sides by 4
24/4 = p
p = 6

Karl makes exactly $65000 a year as an electrician. If his federal income tax is 18% and his social security is 7%. What is Karls net income to base his budget on?
Answer: Karl's net income is 48,750
This does not count state and local taxes, but those are not part of this question.
Step-by-step explanation:
Multiply 65000 × 0.18 to find the federal income tax: $11,700
Multiply 65000 × 0.07 to find the social security tax: $4550
Add those together to find the total tax to be subtracted from his gross income:
11700 + 4550 = 16250
$65,000 - $16,250 = $48,750
