Imagine that you need to buy some chicken for dinner tonight. You found an ad showing that the store across town has chicken on sale for $1.59 a pound. Your usual neighborhood store sells the same chicken for $2.89 a pound. Is it worth the extra drive?
Look at the information below you’ll need to solve the problem.
How much chicken will you be buying? 3 pounds
How does the distance and the time it takes to get there, compare between the two stores? Your neighborhood store is 2.1 miles away, and takes about 8 minutes. The store across town is 8.6 miles away, and takes about 24 minutes.
What kind of mileage does your car get? It averages about 22 miles per gallon in the city.
How many gallons of fuel does your car hold? About 13 gallons
How much is gas? About $1.98/gallon right now.
Are there any other pieces of information you need to solve the problem? Which option would you choose? Is going to the further store cheaper? Or is going to the close store cheaper? How much money does the cheaper option save you? Give your answer to the nearest cent.
Answer:
Step-by-step explanation:
Considering the store in your neighborhood, price per pound of chicken is $2.89. The cost of 3 pounds is
3 × 2.89 = $8.67
Distance = 2.1 miles
The car averages about 22 miles per gallon in the city. It means that the number of gallons needed is
2.1/22 = 0.095 gallons
Cost of gas = $1.98/gallon
Cost of 0.095 gallons =
1.98 × 0.095 = $0.1881
Total cost = 8.67 + 0.1881 = $8.86
Considering the store across town, price per pound of chicken is $1.59. The cost of 3 pounds is
3 × 1.59 = $4.77
Distance = 8.6 miles
The car averages about 22 miles per gallon in the city. It means that the number of gallons needed is
8.6/22 = 0.39 gallons
Cost of gas = $1.98/gallon
Cost of 0.39 gallons =
1.98 × 0.39 = $0.77
Total cost = 4.77 + 0.77 = $5.54
Therefore, it is cheaper going to the further store. The amount that the cheaper option saves is
8.86 - 5.54 = $3.32

Estimate the volume of the solid that lies below the surface z = ex+y and above the rectangle
1. The volume under the surface [tex]f(x,y)=e^{x+y}[/tex] is given by the double integral,
[tex]\displaystyle\int_0^1\int_0^1e^{x+y}\,\mathrm dx\,\mathrm dy[/tex]
We split up the integration region into a 2x3 grid of rectangles whose upper right corners are determined by the right endpoints of the partition along either axis. That is, we split up the [tex]x[/tex] interval [0, 1] into 2 subintervals,
[0, 1/2], [1/2, 1]
with right endpoints given by the arithmetic sequence,
[tex]r_i=0+\dfrac{i(1-0)}2=\dfrac i2[/tex]
for [tex]i\in\{1,2\}[/tex], and the [tex]y[/tex] interval [0, 1] into 3 subintervals,
[0, 1/3], [1/3, 2/3], [2/3, 1]
with right endpoints
[tex]r_j=0+\dfrac{j(1-0)}3=\dfrac j3[/tex]
for [tex]j\in\{1,2,3\}[/tex].
Then the upper right corners of the 6 rectangles are the points
(1/2, 1/3), (1/2, 2/3), (1/2, 1), (1, 1/3), (1, 2/3), (1, 1)
generated by the sequence [tex](r_i,r_j)[/tex].
The integral is thus approximated by the sum
[tex]\displaystyle\sum_{j=1}^3\sum_{i=1}^2f(r_i,r_j)\dfrac{1-0}m\dfrac{1-0}n=\dfrac16\sum_{j=1}^3\sum_{i=1}^2f(r_i,r_j)=\frac{e^{5/6}+e^{7/6}+e^{4/3}+e^{5/3}}6[/tex]
or approximately 2.4334. (Compare to the actual value of the integral, which is close to 2.952.)
For the midpoint rule estimate, we replace the sampling points [tex](r_i,r_j)[/tex] with [tex](m_i,m_j)[/tex], i.e. the midpoints of each subinterval, so the set of sampling points is
(1/4, 1/6), (3/4, 1/6), (1/4, 1/2), (3/4, 1/2), (1/4, 5/6), (3/4, 5/6)
and the integral is approximately
[tex]\displaystyle\sum_{j=1}^3\sum_{i=1}^2f(m_i,m_j)\dfrac{1-0}m\dfrac{1-0}n=\frac{e^{5/12}+e^{3/4}+e^{11/12}+e^{13/12}+e^{5/4}+e^{19/12}}6[/tex]
or about 2.908.
2. We approach the second integral the same way. Split up the [tex]x[/tex] interval into 8 subintervals with left and right endpoints given respectively by
[tex]\ell_i=-2+\dfrac{(i-1)(2-(-2))}8=\dfrac{i-5}2[/tex]
[tex]r_i=-2+\dfrac{i(2-(-2))}8=\dfrac{i-4}2[/tex]
for [tex]i\in\{1,2,\ldots,8\}[/tex], and the [tex]y[/tex] interval into 2 subintervals with
[tex]\ell_j=0+\dfrac{(j-1)(2-0)}2=j-1[/tex]
[tex]r_j=0+\dfrac{j(2-0)}2=j[/tex]
for [tex]j\in\{1,2\}[/tex].
The upper left corners of the rectangles in this grid are given by the sequence [tex](\ell_i,r_j)[/tex]. So the integral is approximately
[tex]\displaystyle\sum_{j=1}^2\sum_{i=1}^8f(\ell_i,r_j)\frac{2-(-2)}m\frac{2-0}n=51[/tex]
(Compare to the actual value, 32.)

Percentage is a ratio in the form of fraction of 100.
Percentage is defined by the "%" symbol.
What is the required value of the car ?At the start of the year 2014, Mike's car was worth £12000.
The value of the car decreased by 30% every year.
So, The value of the car at the start of 2015 = £12000×[tex](1-\frac{30}{100})[/tex]
= £ 12000×[tex]\frac{7}{10}[/tex]

a cylinder has a volume of (x+5) (x^2+10x+25)pi and a diameter of 2x+10. Find the height. PLEASE HELP
Answer:
Height = (x² + 10x + 25)
Step-by-step explanation:
We are given;
volume of cylinder; v = (x+5)•(x² + 10x + 25)π
Diameter = 2x + 10
So radius;r = diameter/2 = (2x + 10)/2 = x + 5
Now,formula for volume of cylinder is;
V = πr²h
Where r is radius and h is height
Plugging in the relevant values, we have;
(x+5)•(x² + 10x + 25)π = π(x + 5)*h
Dividing both sides by π(x + 5) gives us;
h = (x² + 10x + 25)

A highway has an optional toll lane that drivers may take to reduce the time they spend driving. Drivers pay a small fee to enter the toll lane ($0.25). Then, once they leave the toll lane, they pay a fee based on the number of miles they have traveled on the toll lane. Assume that the driver may leave the lane after any whole number of miles, and pays for exactly that number, without rounding up. Note that there is a linear relationship between the number of miles a vehicle has traveled and the price of the toll.
# of Miles traveled on toll lane Toll ($)
0 .25
1 1.00
2 1.75
5 4.00
10 7.75
A. If Frank is on the toll road for 8.00 miles and then leaves the lane, how much will he have to pay total for the trip?

If each person pays about $2.31 (which includes their contribution to the toll lane entry fee), how many miles do they travel on the toll lane?
Answer:
A. If Frank is on the toll road for 8.00 miles and then leaves the lane, how much will he have to pay total for the trip?
$6.25B. Each day, Susan has to pay a toll of $10.00 when she uses the toll lane to get to school. How many miles does Susan travel on the toll lane to get to school?
13 milesC. John started a carpool with his coworkers to save money. He and his three passengers split the cost of the toll. If each person pays about $2.31 (which includes their contribution to the toll lane entry fee), how many miles do they travel on the toll lane?
9 milesStep-by-step explanation:
the toll lane charges $0.25 fixed plus $0.75 per mile driven: fee = $0.25 + $0.75miles
a) Frank ⇒ $0.25 + (8 x $0.75) = $6.25
b) Susan ⇒ $10 - $0.25 = $9.75 / 0.75 = 13 miles
c) John ⇒ $2.31 x 3 = $6.93 - $0.25 = $6.68 / 0.75 = 8.91 ≈ 9 miles. Each passenger should pay $2.33 because the total toll lane fee is $7.

According to the Gallup survey, 23% of Americans reported eating less meat in the past year than they had previously. Results for this Gallup poll are based on telephone interviews conducted Sept. 16-30, 2019, with a random sample of 2,431 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia. Test that the proportion of Americans who reduced meat consumption last year is less than 0.25. Use α = 0.05. State the rejection region. Group of answer choices z > 1.65 z > 1.65 z < − 1.65 z < − 1.65 z > 1.96 z > 1.96
Answer:
Null hypothesis:[tex]p\geq 0.25[/tex]

The statistic would be given by:
[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)
Now we need to find the critical value for the rejection zone of the null hypothesis. Since we have a left tailed test we need to find in the normal standard distirbution a value who accumulate 0.05 of the area in the left tail and we got:
[tex] z_{crit}= -1.65[/tex]
And the best choice for this case would be:
z < − 1.65
Step-by-step explanation:

[tex]p_o=0.25[/tex] is the value that we want to test
[tex]\alpha=0.05[/tex] represent the significance level
Confidence=95% or 0.95
z would represent the statistic
Hypothesis to test
We want to verify if the true proportion of Americans who reduced meat consumption last year is less than 0.25, then the system of hypothesis are :
Null hypothesis:[tex]p\geq 0.25[/tex]
Alternative hypothesis:[tex]p < 0.25[/tex]
The statistic would be given by:
[tex]z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}[/tex] (1)
Now we need to find the critical value for the rejection zone of the null hypothesis. Since we have a left tailed test we need to find in the normal standard distirbution a value who accumulate 0.05 of the area in the left tail and we got:
[tex] z_{crit}= -1.65[/tex]

A binomial probability experiment is conducted with given parameters. Compute the probability of x successes in the n independent trials of the experiment.
N=15, p=0.2,×=4
Answer:
P(X = 4) = 0.1876
Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
In this question:
[tex]n = 15, p = 0.2[/tex]
We want P(X = 4). So
[tex]P(X = 4) = C_{15,4}.(0.2)^{4}.(0.8)^{11} = 0.1876[/tex]
William wants to invest $30,000 in a mutual fund.
a) Bank A has an annual interest rate of 6.5% for 5 years. How much money will he have
at the end of the 5 years? $
Answer:
He will have $39,750 at the end of five years.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
[tex]T = E + P[/tex]
In this question:
[tex]P = 30000, I = 0.065, t = 5[/tex]
Interest earned:
[tex]E = P*I*t = 30000*0.065*5 = 9750[/tex]
Total amount:
[tex]T = E + P = 9750 + 30000 = 39750[/tex]
He will have $39,750 at the end of five years.
