Brian will receive £[tex]1.75[/tex] from Sue buying [tex]500[/tex] grams of berries.
What is grams vs. kg?The metric measure for a tiny amount of mass and weight is the gram (g). It weighs the same as one milliliter (or one cubic centimeter) of water. 1,000 grams make to one kilogram (kg). One liter liquid water weighs exactly one kilogram (kg).
How should I weigh a gram?Using a scale is the most accurate technique to measure in grams. Kitchen spoons and cups, for example, offer an approximate approximation. Moreover, always have a conversion tool or chart on available so you can estimate grams without a scale.
Brian paid a total of £[tex]15.75[/tex] for [tex]4\frac{1}{2}[/tex] kg of strawberries. To find out the price per gram, we can divide the total cost by the total weight:
Price per gram [tex]=[/tex]Total cost / Total weight
Total weight of strawberries [tex]= 4.5 kg = 4500 grams[/tex]
Price per gram [tex]=[/tex] £[tex]15.75 / 4500[/tex] grams
Price per gram [tex]=[/tex] £[tex]0.0035[/tex] per gram
So, Brian paid £[tex]0.0035[/tex] for every gram of strawberries he picked.
Cost of [tex]500[/tex] grams [tex]=[/tex] [tex]500 grams *[/tex] £[tex]0.0035/gram[/tex]
Cost of [tex]500[/tex] grams [tex]=[/tex] £[tex]1.75[/tex]
Therefore, Sue should pay Brian £[tex]1.75[/tex] for [tex]500[/tex] grams of strawberries.

A game Is played using one die. If the die is rolled and shows 3, the player wins $15. M the die shows any number other than 3, the player wins nothing. Complete parts (a) through (0)
a. If there is a charge of $3 to play the game, what is the game's expected value?
Answer:
0
Step-by-step explanation:
Expected Value = (Probability of winning) x (Amount won) + (Probability of losing) x (Amount lost)
In this case, the probability of winning is 1/6 (since there is only one way to roll a 3 out of six possible outcomes), and the probability of losing is 5/6 (since there are five other outcomes that do not result in a win).
The amount won is $15, and the amount lost (i.e., the cost of playing the game) is $3.
Therefore, the expected value is:
Expected Value = (1/6) x $15 + (5/6) x (-$3)
Expected Value = $2.50 - $2.50
Expected Value = $0

Graciela needs to design a can with radius 2
inches and surface area as close to 100
square inches as possible. What is the height of the can? (Use π=3.14
, and round your answer to the nearest inch.)
The height of the can should be approximately 7 inches to have a surface area as close to 100 square inches as possible.
What is cylinder?
A cylinder is a three-dimensional geometric shape that consists of two parallel circular bases of the same size and shape, and a curved lateral surface connecting the bases.
The formula for the surface area of a cylinder is:
SA = 2πr² + 2πrhwhere r is the radius of the base, h is the height, and π is approximately 3.14.
In this case, the radius is given as 2 inches, and we want to find the height that will give us a surface area as close to 100 square inches as possible. So we need to solve for h in the equation:
100 = 2π(2)² + 2π(2)h
Simplifying this equation:
100 = 8π + 4πh
92 = 4πh
h = 23/π
h ≈ 7.32
Rounding this answer to the nearest inch, we get:
h ≈ 7 inches
Therefore, the height of the can should be approximately 7 inches to have a surface area as close to 100 square inches as possible.

The rate of change is $1.25 per premium movie watched.
A. $1.25 / 1 premium movie
How to find the rate of changeThe rate of change in this scenario is the increase in cost for each additional premium movie watched.
In this case, the rate of change is constant, since the cost per premium movie remains the same regardless of the number of premium movies watched.
Therefore, the rate of change is simply the additional cost per premium movie, which is $1.25.
So, for example, if you watched 10 premium movies, the total cost would be:
$35 + (10 * $1.25) = $47.50
And if you watched 20 premium movies, the total cost would be:
$35 + (20 * $1.25) = $60.00
rate of change = (60 - 47.5) / (20 - 10) = 1.25
In both cases, the rate of change is still $1.25 per premium movie watched.

PLS HELP , in need to solve by using substitution and with checks
Answer:
(x, y) = (-1/2, 5/2)
Step-by-step explanation:
To solve this system of equations using substitution, we can use the first equation to express y in terms of x, and then substitute that expression into the second equation to get an equation in terms of x alone.
Starting with the first equation, we have:
y = x + 3
We can now substitute this expression for y into the second equation:
3x + 3y = 6
3x + 3(x + 3) = 6
Simplifying the right-hand side:
3x + 3x + 9 = 6
6x = -3
x = -1/2
Now that we have solved for x, we can substitute this value back into the first equation to find y:
y = x + 3
y = -1/2 + 3
y = 5/2
Therefore, the solution to the system of equations is (x, y) = (-1/2, 5/2).
To check our solution, we can substitute these values back into both equations and verify that they hold true:
y = x + 3
5/2 = -1/2 + 3
5/2 = 5/2
This equation holds true, so the first equation is satisfied by our solution.
3x + 3y = 6
3(-1/2) + 3(5/2) = 6
-3/2 + 15/2 = 6
6 = 6
This equation also holds true, so the second equation is satisfied by our solution as well.
Therefore, we can conclude that our solution is correct.
The equations have two variables, x and y, and we can use substitution to solve for one variable in terms of the other. By substituting the expression for y into the second equation and solving for x, we get the value of x as -1/2. We can then substitute this value back into the first equation to get the value of y, which is 5/2. This means that the solution to the system of equations is (x, y) = (-1/2, 5/2) and we can check that this solution satisfies both equations.

Julia made a die for a game. It had 5 faces, labeled 1-5. Because of the shape of the die, it was biased in favor of rolling a 3. We do not know the amount of bias. She experimented to estimate how likely it was for a 3 to be rolled and her results are in the above table. Using her experimental results, find the best estimate of the probability of rolling a 3.
From the table, we see that Julia rolled the die 100 times, and the number of times she rolled a 3 was 45.
The best estimate of the probability of rolling a 3 can be found by dividing the number of times a 3 was rolled by the total number of rolls:
P(rolling a 3) = Number of times 3 was rolled / Total number of rolls
P(rolling a 3) = 45 / 100
P(rolling a 3) = 0.45 or 45%
Therefore, based on Julia's experimental results, the best estimate of the probability of rolling a 3 on her biased die is 0.45 or 45%.

prove that every bounded sequence contain a convergent subsequence
Answer:
To prove that every bounded sequence contains a convergent subsequence, we will use the Bolzano-Weierstrass theorem.
Bolzano-Weierstrass theorem: Every bounded sequence in Euclidean space has a convergent subsequence.
Proof: Let (a_n) be a bounded sequence in Euclidean space, which means that there exists some M > 0 such that |a_n| <= M for all n. We will use the bisection method to construct a subsequence that converges to some limit L.
Step 1: Divide the interval [-M, M] into two subintervals, [-M, 0] and [0, M]. Since (a_n) is bounded, at least one of these intervals contains infinitely many terms of the sequence. Let's call the interval that contains infinitely many terms I_1.
Step 2: Divide I_1 into two subintervals of equal length, and again, at least one of these subintervals must contain infinitely many terms of the sequence. Let's call the interval that contains infinitely many terms I_2.
Step 3: Repeat this process for each subinterval, dividing it into two subintervals of equal length and choosing the one that contains infinitely many terms of the sequence. We obtain a sequence of nested intervals I_1 ⊃ I_2 ⊃ I_3 ⊃ ... that contain infinitely many terms of the sequence.
Step 4: Since the length of each interval is decreasing and they are nested, the intersection of all the intervals is a single point L. By construction, every term of the sequence (a_n) belongs to one of the intervals I_k, which means that there exists a subsequence (a_nk) that converges to L.
Therefore, every bounded sequence in Euclidean space has a convergent subsequence, as required.

A 6 foot 2 man casts a shadow of 5 feet. What size shadow will a 5
foot 5 lady cast?
The 5 foot 5 tall lady will cast a shadow of approximately 4.4 ft.
What size shadow will the 5 foot 5 lady cast?Given that, a 6 foot 2 man casts a shadow of 5 feet. Also, a lady is 5 foot 5 and we find the shadow she casted.
We can solve this problem by setting up a proportion:
The height and shadow length are proportional, so we can write:
6 feet 2 inches : 5 feet = 5 feet 5 inches : x
where x is the length of the shadow cast by the lady.
To solve for x, we can cross-multiply:
(6 feet 2 inches) × x = (5 feet) × (5 feet 5 inches)
To simplify the calculation, we can convert all the lengths from feets to inches:
Note: 1 ft = 12 in
(74 inches) × x = (60 inches) × (65 inches)
Now we can solve for x:
x = (60 inches) × (65 inches) / (74 inches)
x = 3900/74
x = 52.70 inches
Convert back to ft
x = 4.4 ft
Therefore, the lady will cast a shadow of approximately 4.4 ft.
