Minimum price: Increases.
Maximum price: Remains the same.
Range: Increases.
Mean (Average) price: Cannot be determined.
When the kid's meal is added to the menu, the effect on the statistics of the meal prices can be determined as follows:
Minimum Price: Increases
Adding the kid's meal, which costs $2.35, to the menu will increase the minimum price.
Therefore, the value of the minimum price statistic will increase.
Maximum Price: Increases
Since the maximum price of the kid's meal ($2.35) is lower than the previous maximum price of $12.10, adding the kid's meal to the menu will not change the maximum price.
Therefore, the value of the maximum price statistic remains the same.
Range: Increases
The range is calculated as the difference between the maximum and minimum prices.
As the minimum price increases while the maximum price remains the same, the difference between them (the range) will increase.
Therefore, the value of the range statistic will increase.
Mean (Average) Price: Cannot be determined
To determine the effect on the mean price, we would need information about the number of meal options available and their individual prices. Without this information, we cannot determine whether the mean price will increase, decrease, or remain the same.
Therefore, the value of the mean price statistic cannot be determined.
In summary:
Minimum price: Increases
Maximum price: Remains the same
Range: Increases
Mean (Average) price: Cannot be determined

find the length of bc
give your answer to 3 signifcant figures
Using the cosine ratio, side BC in the right-angled triangle is approximately 19.4 cm when rounded to three significant figures.
In the right-angled triangle ABC, where angle A is 90 degrees, side AB is the base, side AC is the perpendicular, and side BC is the hypotenuse, we can use trigonometry to find the length of BC.
The cosine ratio (cos) relates the adjacent side to the hypotenuse in a right-angled triangle. In this case, cos(B) = AB/BC. To find BC, rearrange the formula to BC = AB/cos(B).
Given AB = 6.3 cm and angle B = 71 degrees, substitute these values into the formula:
[tex]\[ BC = \frac{6.3 \, \text{cm}}{\cos(71^\circ)} \][/tex]
Using a calculator, find that cos(71 degrees) is approximately 0.325. Now, divide 6.3 cm by this value:
[tex]\[ BC \approx \frac{6.3 \, \text{cm}}{0.325} \approx 19.385 \, \text{cm} \][/tex]
Rounded to three significant figures, the length of side BC is approximately 19.4 cm.

identify the arc length of TV in terms of pie with radius of 5
A sphere has a volume of 4500pi cubic feet what is the radius of the sphere
Given a volume of 4500π cubic feet, the radius is found to be approximately 15 feet after solving the equation.
To find the radius of a sphere given its volume, we use the formula for the volume of a sphere: V = (4/3)πr³. In this case, the given volume is 4500π cubic feet. To solve for the radius, we can set up the equation as follows:
V = (4/3)πr³
4500π = (4/3)πr³
To isolate r³, we divide both sides by π and then multiply by 3/4:
4500 = (4/3)r³
(3/4) * 4500 = r³
3375 = r³
Now, we take the cube root of both sides to find the radius:
r = ³√3375
r ≈ 15 feet
Therefore, the radius of the sphere is approximately 15 feet.
the radius of the sphere is 15 feet.
The formula for the volume [tex](\( V \))[/tex] of a sphere in terms of its radius [tex](\( r \))[/tex] is:
[tex]\[ V = \frac{4}{3}\pi r^3 \][/tex]
Given that the volume of the sphere is [tex]\( 4500\pi \)[/tex] cubic feet, we can set up the equation:
[tex]\[ 4500\pi = \frac{4}{3}\pi r^3 \][/tex]
To find the radius [tex]\( r \)[/tex], we need to isolate it in the equation. First, let's cancel out [tex]\( \pi \):[/tex]
[tex]\[ \frac{4500\pi}{\pi} = \frac{4}{3} r^3 \][/tex]
[tex]\[ 4500 = \frac{4}{3} r^3 \][/tex]
Now, to solve for [tex]\( r \)[/tex], we'll multiply both sides by [tex]\( \frac{3}{4} \)[/tex] to isolate [tex]\( r^3 \):[/tex]
[tex]\[ r^3 = \frac{4500 \times 3}{4} \][/tex]
[tex]\[ r^3 = \frac{13500}{4} \][/tex]
[tex]\[ r^3 = 3375 \][/tex]
Now, to find ( r ), we'll take the cube root of both sides:
[tex]\[ r = \sqrt[3]{3375} \][/tex]
[tex]\[ r = 15 \][/tex]
So, the radius of the sphere is 15 feet.
Evelyn is working two summer jobs, making $18 per hour lifeguarding and making $11 per hour tutoring. In a given week, she can work a maximum of 15 total hours and must earn no less than $200. If Evelyn worked 8 hours lifeguarding, determine the maximum number of whole hours tutoring that she can work and still meet her requirements.
Given Evelyn's hourly rates for both of her jobs and the total number of working hours she has, Evelyn can work a maximum of 7 hours tutoring if she has already spent 8 hours lifeguarding.
Explanation:To solve this problem, we first calculate the total earning from lifeguarding by multiplying the hourly rate by the number of hours she worked, which results in $18 * 8 = $144. The minimum total earning she must make is $200, so she still needs to earn $200 - $144 = $56. Since she is making $11 per tutoring hour, she will need to work a minimum of $56 / 11 which is approximately 5 hours. However, these are still part of the total of 15 hours maximum she can work, and she has already worked 8 hours lifeguarding, meaning she can work at most 15 - 8 = 7 hours tutoring in the remaining time.

To solve this problem, we can use a combination of inequalities to represent the given constraints.
We need to solve these inequalities simultaneously to find the maximum number of whole hours Evelyn can work as a tutor.
1. The first inequality:
[tex]\[ x + 8 \leq 15 \][/tex]
[tex]\[ x \leq 15 - 8 \][/tex]
[tex]\[ x \leq 7 \][/tex]
2. The second inequality:
[tex]\[ 18(8) + 11x \geq 200 \][/tex]
[tex]\[ x \geq \frac{56}{11} \][/tex]
[tex]\[ x \geq 5.09 \][/tex]
Since the number of tutoring hours must be a whole number, Evelyn can work a maximum of 5 whole hours tutoring and still meet her requirements.
Therefore, the maximum number of whole hours tutoring that Evelyn can work while still meeting her requirements is 5 hours.

The diagram shows a partly filled water tank.
A third of the tank is filled with water.
1 cubic metre is equivalent to 1000 litres.
Work out the quantity of water in the tank.
Give your answer in litres.
Answer:
8000 litres
Step-by-step explanation:
⅓ (4 × 2.5 × 2.4)
= 8 m³
1 m² = 1000 litres
8 m³ = 8000 litres
The volume of water in the tank in litres can be found by calculating one third of the capacity of the tank in cubic metres and then multiplying that by 1000. We represent this as 1000X/3 litres, where X is the total capacity of the tank in cubic metres.
Explanation:To solve this problem, we firstly need to know the total capacity of the tank in cubic metres. Since we don't have this specific information in the question, let's call this capacity as 'X' cubic metres.
One third of the tank is filled with water, so the volume of water in the tank is one third of X, which is (1/3) * X cubic metres. We know that 1 cubic metre is equivalent to 1000 litres, therefore, the volume of the water in the tank in litres is (1/3) * X * 1000, which simplifies to 1000X/3 litres.

Explanation:The student has asked to simplify the expression Sq -16+sq-25+5. This appears to be a typo, and I believe they are referring to square roots. The correct mathematical expression to simplify should be √(-16) + √(-25) + 5. The simplification of the square roots involving negative numbers results in imaginary numbers because the square root of a negative number is not defined in the set of real numbers but rather in complex numbers. For the given expression, complex numbers and imaginary units ('i', wherein i^2 = -1) will be introduced in simplification:

Step-by-step explanation:
what rule matches the function represented by the table?
Let's try a line
y = mx + b
From (0,4):
4 = 0x + b
b = 4
So far we have
y = mx + 4
From (1,1)
1 = m(1) + 4
-3 = m
Our rule is y = -3 x + 4
Let's check the other points:
-3(-4)+4 = 12+4 = 16 good
-3(4)+4 = -12+4 = -8 good
-3(9) + 4 = -23 good
Answer: y = -3 x + 4
The rule matching a function as shown by a table can be determined by analyzing the difference and relationship between x-values and y-values. This might represent a linear, exponential, or quadratic relationship, which can be described by a range of mathematical equations.
Explanation:Unfortunately, without having the actual table and data, it is hard to give an accurate rule for the function. However, generally, in order to define a rule that matches a function represented by a table, you would need to discern a pattern between the inputs (often represented by the x-values) and the outputs (represented by the y-values).
In some cases, this might be a simple linear rule where each step in the x-values increases or decreases the y-values by a consistent rate; this would represent a formula of the format y = mx + b, where m is the change in y over the change in x, and b is the y-value when x = 0. Alternately, more complex relationships (such as exponential or quadratic rules) might be represented and would need different formulas to be described properly.
Determining the rule can often involve finding the rate of change between pairs of data points and discerning what kind of relationship this reveals. The explanation and answer would then match this established pattern.

if you divide 30 by half and add ten, what do you get?
Answer:
70
Step-by-step explanation:
Dividing is multiplying by the reciprocal.
So 30 divided by 1/2
is like 30(2)=60
Then add 10 so 60+10=
70
The equivalent value of the expression "dividing 30 by half and adding ten" is 70.
Given data:
Regarding step-by-step dissecting of "dividing 30 by half and adding ten"
Step 1 is to divide 30 in half.
A number is effectively divided by 1/2 when we divide it in half. A fraction's reciprocal is what you multiply by when you divide by it. 1/2 has a reciprocal of 2/1, or only 2.
As a result, multiplying 30 by 2 is equivalent to dividing it in half:
To make the equation simpler:
30 ÷ (1/2) = 30 × 2
= 60
Step 2: Ten-folding.
We obtain 60 by dividing 30 in half.
Now double the outcome by ten:
60 + 10 = 70
So, when you multiply 30 by half, add 10, and you get 70.
Hence, the equation is solved and the solution is 70.
