In London. I pint of milk costs 58p.
In Paris, 1 litre of milk costs 1.05 euros.
1 litre = 1.76 pints
£1 = 1.17 euros
In which city is the milk better value for money, London or Paris?
You must show your working.
Comparing the equivalent cost of Milk in Euro in the two countries, then we can conclude that Milk is a better value for money in Paris.
In other to make accurate comparison of the cost ; we need to using the same unit or milk and same currency value :
Cost of 1 pint of Milk in London :
1 pint = 0.58 pounds
The equivalent value of 1 pint of Milk in terms of Euro in London will be :
1 pound = 1.17 euro
0.58 pound = x
Cross multiply :
x = 1.17 × 0.58
x = 0.6786 euro
x = 0.68 euro
Hence, 1 pint of Milk cost 0.68 euro in London
Cost of 1 pint of Milk in Paris :
1 Litre = 1.76 pint
Hence,
1.76 pint = 1.05 euro
1 pint = c
1.76c = 1.05
c = 1.05 / 1.76
c = 0.597 euro
Hence, cost of 1 pint of Milk cost 0.60 euro in Paris
Therefore, since the cost of Milk in Paris cost less in Paris than in London, then Milk is a better value for money in Paris.

At HD Sport & Fitness gym, analysis shows that, as the demand of the gym, the number of members is 83 when annual membership fee is $17 per member and the number of members is 81 when annual membership fee is $24 per member. As the operator of the gym, you found out that number of members (q) and membership fee (p) have a linear relationship.
A) At what membership price, p, is the revenue maximized?
p=$??. Round your answer to 2 decimal places.
B) What is the maximum annual revenue?
R=$??. Round your answer to 2 decimal places.
Note: Round all coefficients of your revenue function to 2 decimal places.
The price at which revenue is maximized is $ 157, and maximum annual revenue is $ 6751.
Since at HD Sport & Fitness gym, analysis shows that, as the demand of the gym, the number of members is 83 when annual membership fee is $ 17 per member and the number of members is 81 when annual membership fee is $ 24 per member, and the number of members and membership fee have a linear relationship, to determine at what membership price is the maximized revenue, and what is the maximum annual revenue, the following calculations must be performed:
17 x 83 = 1411 24 x 81 = 1944 31 x 79 = 2449 38 x 77 = 2926 66 x 69 = 4554 73 x 67 = 4891 80 x 65 = 5200 94 x 61 = 5734 101 x 59 = 5959 122 x 53 = 6466 129 x 51 = 6579 150 x 45 = 6750 157 x 43 = 6751 164 x 41 = 6724

whats 186,282 rounded to the nearest thousand ?
Answer: 186,000
Step-by-step explanation:
You round the 282 down so that it is an even thousand. <3
186,282 rounded to the nearest thousand is 186,000.
To round 186,282 to the nearest thousand, we look at the digit in the thousands place, which is '6'.
If the digit in the hundreds place is 5 or greater, we round up. If it is less than 5, we round down.
In this case, since the digit in the hundreds place is '8', which is greater than 5, we round up.
To round up, we increase the digit in the thousands place by 1 and replace all the digits to the right with zeros.
Therefore, rounding 186,282 to the nearest thousand gives us 187,000.

in a standard normal distribution, the probability that z is greater than zero is
Answer:
50%
Step-by-step explanation:
The distribution is symmetrical about the y-axis.
The probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.
What is Probability?The branch which deals with the occurrence of a random event is known as probability.
The area under the curve to the right of z = 0 is equal to the area under the curve to the left of z = 0. So the standard normal distribution is symmetric about the mean of zero
As the total area under the curve is equal to 1, each of these areas must be 0.5 or 50%.
In a standard normal distribution, the probability that z is greater than zero is 0.5, or 50%.
Therefore, the probability that z is greater than zero in a standard normal distribution is 0.5 or 50%.

Answer:
$513.75
Step-by-step explanation:
Let h represent the number of hours he worked in a week
An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends.
Hence, his pay Is represented by equation:
$498.75 + $2.50 × x
If he works 6 hours on the weekend in addition to the 35 hours during the week
$498.75 + $2.50 × 6
= $498.75 + $15
= $513.75
Therefore, he earns $513.75
7/1 − 3 ( 7/3n − 7/2 )
Answer:
[tex]\frac{35}{2}[/tex] - [tex]7n[/tex]
Step-by-step explanation:
7/1 − 3( 7/3n − 7/2 )
Anything divided by one gives itself.
7 - 3 ( [tex]\frac{7}{3}n - \frac{7}{2}[/tex])
Use the distributive property to multiply −3 by [tex]\frac{7}{3}n - \frac{7}{2}[/tex])
7 - 3 × ([tex]\frac{7}{3}[/tex][tex]n[/tex] - 3 (-[tex]\frac{7}{2}[/tex])
Multiply −3 times [tex]\frac{7}{3}[/tex]
7 - 7n - 3 (-[tex]\frac{7}{2}[/tex])
Express -3 (-[tex]\frac{7}{2}[/tex]) as a single fraction.
7 - 7n + [tex]\frac{-3(-7)}{2}[/tex]
Multiply −3 and −7 to get 21.
7 - 7n + [tex]\frac{21}{2}[/tex]
Convert 7 to fraction [tex]\frac{14}{2}[/tex]
[tex]\frac{14}{2}[/tex] - 7n + [tex]\frac{21}{2}[/tex]
Since [tex]\frac{14}{2}[/tex] and [tex]\frac{21}{2}[/tex] have the same denominator, add them by adding their numerators.
[tex]\frac{14 + 21}{2} - 7n[/tex]
Add 14 and 21 to get 35.
[tex]\frac{35}{2} - 7n[/tex]
