Answer:
The sample size is [tex]n = 3457 [/tex]
Step-by-step explanation:
From the we are told that
The population proportion is p = 0.90
The margin of error is E = 0.01
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally the sample size is mathematically represented as
[tex]n =[ \frac{ Z_{\frac{\alpha }{2} } }{E} ]^2 * p(1-p)[/tex]
=> [tex]n =[ \frac{ 1.96 }{0.01} ]^2 * 0.90(1-0.90)[/tex]
=> [tex]n = 3457 [/tex]
Compare the proportional relationships. Which represents the greatest price per pound of walnuts
Answer:
B. Weight
Price
The price per pound of walnuts is the slope or unit rates of the graphs, lines and equations
The greatest price per pound of walnuts is $14.00
(a) Cost of 1.5 bags is $12.99
The unit rate is calculated as:
[tex]\mathbf{Rate = \frac{Cost}{Bags}}[/tex]
So, we have:
[tex]\mathbf{Rate = \frac{\$12.99}{1.5}}[/tex]
[tex]\mathbf{Rate = \$8.66}[/tex]
The price per pound of walnuts is $8.66
(b) The table
From the table, we have the following points
[tex]\mathbf{(x,y) =(0.2,2.80)\ (0.4, 5.60)}[/tex]
The unit rate is calculated as:
[tex]\mathbf{Rate = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{Rate = \frac{5.60 - 2.80}{0.4 - 0.2}}[/tex]
[tex]\mathbf{Rate = 14}[/tex]
The price per pound of walnuts is $14.00
(c) The graph
From the table, we have the following points
[tex]\mathbf{(x,y) =(0,0)\ (1, 11)}[/tex]
The unit rate is calculated as:
[tex]\mathbf{Rate = \frac{y_2 - y_1}{x_2 - x_1}}[/tex]
So, we have:
[tex]\mathbf{Rate = \frac{11 - 0}{1 - 0}}[/tex]
[tex]\mathbf{Rate = 11}[/tex]
The price per pound of walnuts is $11.00
By comparison, the greatest price per pound of walnuts is $14.00

The town’s highway department marks a new road with reflective markers. The road is on a 6 3/4 miles stretch in length. How many markers would be needed if the markers are spaced every 1/8 of a mile?
Answer:
54 markers.
Step-by-step explanation:
First take 6 3/4 which also equals .75 and 1/8 which also equals .125. Now divide 6.75 by 0.125 which equals 54.

Find M<1 in the figure below. PQ and RS are parallel
Answer:
m∠1= 105°
Step-by-step explanation:
The m∠1 and 75° are supplementary angles that sum up to 180°.
The equation here would be: m∠1+75= 180.
Step 1- Subtract 75 to both sides of the equation.
m∠1+75= 180
-75 -75
m∠1= 105
Hope this helps! :)
Answer: The answer would be 105.
Step-by-step explanation:
If you look at the angle's corresponding angle, then you will see that it is right next to angle one. So the angle next to angle one is also 75 degrees because it is the same angle or the corresponding angle to the other one that is 75 degrees. So, together, angle one and the angle next to it should equal 180 degrees. So you subtract 180-75=105. And angle one equals 105.

If a car is traveling 75 miles per hour, how many feet will it travel in 10 seconds ?
If 1 mile= 5280 feet, So If a car is traveling 75 miles per hour, then it is travelling 1100 feet in 10 seconds.
What is 1 mile in ____ feet?1 mile= 5280 feet
A car is traveling 75 miles per hour, we need to find how many feet it travel in 10 sec.
1 hour = 60*60 = 3600 seconds
75 miles: 1 hour
75 miles: 3600 seconds
75/3600 miles: 3600/3600 seconds
1 second: 1/48 mile
1/48 miles = (1/48)*5280 = 110 feet
So you're going 110 ft per second. In other words, the car travels 110 feet in 1 second.
For 10 seconds 110*10=1100.
Therefore 1100 feet will car travel in 10 seconds.

Answer:
x=0 is the solution
Step-by-step explanation:
Notice that the graph is that of a parabola with vertex at the point (0, 0).
When we solve for x in the equation:
- x^2 = 0
then we divide by -1 both sides an get: x^2 = 0/(-1) = 0
and finally use the square root property to find the answer and we get:
[tex]x=+/- \sqrt{0} = +/- 0 = 0[/tex]
Since +0 = - 0 (this is the null value), there is only one solution: x = 0.

Sharon wants to open a checking account from which to pay bills. She wants online services, and a debit card, which both banks provide for free. Based upon past experience, she expects to accidentally overdraft the account 1 time per year, due to unexpected charges and miscommunications. She expects no 2nd copies of statements, and to use network ATMs 4 times per month with either bank. She has $3300 in an emergency savings account at First State Bank, and thinks that the balance will be enough to cover overdrafts in the future if automatic transfers are made when needed.
Answer:
a.No, Common Bank will save Sharon more money.
Step-by-step explanation:
There are two banks i.e. first state bank and the common bank that should be compared in the table depend upon the prices of both the banks
On seeing it we get to know that the first state bank would charged a fee on a monthly basis i.e. $4 while on the other hand the common bank has no fee on the monthly basis
Also the unsufficient bonds are more cheaper in the common bank if we compared with the first state bank
Moreover, the $7 is charged in the first state bank and $3 charged in the common bank.
Therefore the common bank would become cheaper
Hence, the correct option is a.

Charlene and Gary want to make confetti. In order to get the right balance of ingredients for their tastes they bought 3 pounds of paper hearts at $2.46 per pound, 5 pounds of sparkling stars for $3.05 per pound, and 3 pounds of shiny coils for $2.33 per pound. Determine the cost per pound of the coffeti.
Answer:
0.712 cents per pound
Step-by-step explanation:
Since we are given the exact amount of each ingredient as well as the price for that amount then we simply need to calculate how much each pound of the confetti actually costs. We do this by adding together all of the pound of all of the ingredients and then adding together all of the costs. Lastly, we divide the cost by the total amount of pounds to find the cost per pound of the confetti like so...
3lbs. + 5lbs. + 3lbs. = 11 lbs.
$2.46 + $3.05 + $2.33 = $7.84
$7.84 / 11 lbs. = 0.712 cents per pound
Therefore, the cost per pound of the confetti is 0.712 cents per pound

Edward solved the equation 4X + 1 = 5x +(-5)
Add 4 negative both sides
Add 5 negative to both side
=4
What’s was mistake
Answer:
He should have added 5 to each side instead of -5
Step-by-step explanation:
4X + 1 = 5x +(-5)
Subtract 4x from each side
4X-4x + 1 = 5x-4x +(-5)
Combine like terms
1 = x-5
Add 5 to each side
He should add 5 to each side ( we need to add the opposite of (-5)) to undo the adding of (-5)
1+5 = x-5+5

You are buying a new bicycle. The table shows the prices of bicycles at a store. You are willing to pay the mean price with an absolute deviation
of at most $60.
Select which inequalities represent the prices you are willing to pay.
Bicycle prices:
$350 $450 $180 $200
$290 $325 $240 $445
x-60 S 310
| x + 60 < 310
1 x + 310 < 60
x < 250 or x > 370
X - 310 < 60
250 < x < 370
Answer:
250 < x < 370
Step-by-step explanation:
From the given bicycle prices, we first calculate the mean.
Mean = ⅛($350 + $450 + $180 + $200 + $290 + $325 + $240 + $445)
Mean = ⅛(2480)
Mean = $310
Next, is to determine the amount willing to pay using.
Amount = Mean ± Absolute Deviation
Amount = $310 ± $60
This can split as follows
Amount = $310 + $60 or Amount = $310 - $60
Amount = $370 or $250
Represent as an inequality, we have:
250 < x < 370
