while in Manchester, england, chelsea bought a sweater for bitirsh pound 28 . when she returned, she saw the same sweater for C$38. which sweater cost more by how much in canadian dollar show your work pls
Answers
The sweater that cost more is the sweater bought in Manchester. It is more expensive by C$7.40.
Which sweater is more expensive?The exchange rate is the price at which one currency is exchanged for another currency. For example, if the exchange rate of the pound and Canadian dollars is 1.60. It means that 1 unit of the pound would buy 1.60 of the Canadian dollars.
The first step is to convert the cost of the sweater that is priced in the British pound to Canadian dollars.
The exchange rate : 1 British pound = 1.6215 CAD
28 X 1.6215 = 45.402
Difference in price = 45.402 - 38 = C$7.402
Based on the above calculation, the sweater when converted from the British pound to the Canadian dollars, it is more expensive to buy the sweater in Manchester than it is to buy it in Canada.

[9] X is a Gaussian random variable with variance 0.25. The mean of X is estimated by taking the sample mean of independent samples of X. If the mean needs to be estimated within 0.01 from the actual mean with a confidence coefficient of 0.99, find the minimum number of samples needed in the estimation.
Answers
Answer:
The minimum number of samples required is [tex]n = 16641 [/tex]
Step-by-step explanation:
From the question we are told that
The variance is [tex]\sigma^2 = 0.25[/tex]
The margin of error is [tex]E = 0.01[/tex]
From the question we are told the confidence coefficient is 0.99 , hence the level of significance is
[tex]\alpha = (1 - 0.99 ) \%[/tex]
=> [tex]\alpha = 0.01[/tex]
Generally from the normal distribution table the critical value of [tex]\frac{\alpha }{2}[/tex] is
[tex]Z_{\frac{\alpha }{2} } = 2.58[/tex]
Generally the standard deviation is
[tex]\sigma =\sqrt{\sigma^2}[/tex]
=> [tex]\sigma =\sqrt{0.25}[/tex]
=> [tex]\sigma =0.5[/tex]
Generally the sample size is mathematically represented as
[tex]n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2[/tex]
=> [tex]n = [\frac{2.58 } * 0.5 }{0.01 } ] ^2[/tex]
=> [tex]n = 16641 [/tex]
The acceleration of gravity on Mars is about 3.7 meters per second squared. Suppose a rock falls from a tall cliff on Mars. Which of the following equations indicates how fast the rock will be falling after 8 seconds?
Answers
An equation that indicates how fast (velocity) the rock will be falling after 8 seconds is V = (3.7 × 8) m/s.
Given the following data:
Time, t = 8 seconds.Acceleration of gravity on Mars, a = 3.7 meters per second squared (m/s²).How to determine the velocity of this rock?In order to determine the velocity at which this rock would fall after 8 seconds, we would apply the first equation of motion.
Mathematically, the first equation of motion is given by this formula:
V = u + at
Where:
V represents the final velocity.u represents the initial velocity.a represents the acceleration.t represents the time.Substituting the given parameters into the formula, we have;
V = 0 + 3.7 × 8
V = (3.7 × 8) m/s.

The cost function for a certain company is
C = 70x + 200
and the revenue is given by
R = 100x − 0.5x2.
Recall that profit is revenue minus cost. Set up a quadratic equation and find two values of x (production level) that will create a profit of $200.
Answers
Hence , the value of x (production level) that will create a profit of $200 are 40 and 20.
We have given cost function C = 70x + 200 and revenue function R = 100x − 0.5x² .
It is given that profit is revenue minus cost.
P = R -C
P = 100x − 0.5x² - 70x - 200
P = 30x − 0.5x² -200 ........(1)
It is also given that it will create a profit of $200 .
Putting P = 200 in equation (1) , we get
200 = 30x − 0.5x² -200
0.5x² - 30x + 400 = 0
Multiplying by 10 we get
5x² - 300x + 4000 = 0
Taking 5 common , we get
x² - 60x + 800 = 0
By splitting in the middle term this equation can be represented by
x² -(40+20)x +800 = 0
(x² - 40x ) - (20x-800) = 0
x(x-40) - 20( x - 40) = 0
(x - 40) (x- 20) = 0
On comparing , we get
x - 40 = 0
x = 40
and x - 20 = 0
x = 20

Suppose you and 10 friends are taking a road trip for Spring Break. You plan on visiting multiple museums, national parks, and shopping locales along this trip. Your
road trip will a total of 10 days. You drive a total distance of 5000 miles. Some of the drive your average speed was 45 mph. While the rest of the trip was 70 mph.
1. How many hours were you driving each speed? Round 3 decimals
2. What distance did you drive for each speed? Round 3 decimals
Answers
Using the relation between velocity, distance and time, and supposing the group travels for 8 hours a day, it is found that:
1. You were driving 24 hours at 45 mph and 56 hours at 70 mph.
2. You drove 1080 miles at 45 mph and 3920 miles at 70 mph.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
v = d/t.
For the first part, we have that:
The velocity is of 45 mph.The distance is of d.The time is of t.Hence:
v = d/t
45 = d/t
d = 45t.
For the second part, we have that:
The velocity is of 70 mph.The distance is of 5000 - d.The time is of 80 - t. (10 days of 8 hours driving = 80 hours).Hence:
70 = (5000 - d)/(80 - t).
d = 45t, hence:
70 = (5000 - 45t)/(240 - t).
5000 - 45t = 5600 - 70t
25t = 600.
t = 600/25
t = 24. -> (80 - 24) = 56.
d = 45t = 45 x 24 = 1080 -> (5000 - 1080) = 3920.
Hence:
1. You were driving 24 hours at 45 mph and 56 hours at 70 mph.
2. You drove 1080 miles at 45 mph and 3920 miles at 70 mph.

Given m| n, find the value of x.
Answers
Answer:
45°
Step-by-step explanation:
x° = (180 - 135)°
= 45°
Hope this helps
With interior alternate angles and adjacent angles concept, the value of x from the given parallel lines is 45°.
Given that, straight line m parallel to straight line n and t is the transversal.
When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar.
Here, y=135° (Interior alternate angles are equal)
Now, y°+x°=180° (Adjacent angles on straight line)
135°+x°=180°
x°=45°
Therefore, the value of x from the given parallel lines is 45°.

((5.6*10^(-3))*(7.7*10^(-9)))/((8*10^(-2))*(3.5*10^(-6)))=1.54*10^-4
then the other fraction one equals 9.45*10^-4

Jack wants to model a situation where the perimeter of the rectangle to the right is 6 feet plus or minus 1.5 feet. Because he is modeling a length "plus or minus" another length, he decides to use an absolute value equation for his model. Do you agree with his decision? Explain your reasoning.
Answers
The absolute value of the equation will not work because the value of x would have to be negative for the perimeter to be 6 ft plus or minus 1.5 ft.
What is the perimeter of the rectangle?The perimeter of the rectangle is given as:
Perimeter = 2(Length + Breadth)
The perimeter of a rectangle is 6 feet plus or minus 1.5 feet.
So, we have:
Perimeter = 2(Length + Breadth) = 6 feet ± 1.5 feet.
Then Substitute values for length and width
2(Length + Breadth) = 6 feet ± 1.5 feet.
2(4 + x) = 6 feet ± 1.5 feet.
Now,
2(4 + x) = 6 feet + 1.5 feet.
8 + 2x = 6.5 ft
2x = 6.5 - 8
x = -0.25 ft
2(4 + x) = 6 feet - 1.5 feet.
8 + 2x = 4.5 ft
2x = 4.5 - 8
x = -1.75ft
Here Both values of x are negative.
This means that the absolute value model can't work, because a rectangle cannot have a negative dimension.
