I believe so but I’m not sure I remember having that exact question I forgot

a standard wooden pencil typically measures around 7 inches to 7.5 inches in length.

The average length of a pencil can vary depending on factors such as the type of pencil, region, and manufacturer. However, a standard wooden pencil typically measures around 7 inches to 7.5 inches in length. This range encompasses the most common lengths found in the market.

It's important to note that there may be slight variations in length between different pencil brands and styles. Additionally, specialty or novelty pencils may have different lengths based on their design or intended purpose.

To obtain a more accurate average length for a specific set of pencils or a particular region, you would need to measure a representative sample of pencils and calculate the average length based on the measurements obtained.

The linear equation m = 9.50h + 140 represents the amount of money m earned by Mark in h hours while working at the grocery store in summer.

Mark earns $9.50 per hour while working at local grocery store

Total money earned by Mark after working for 16 hours is $292

As per the given condition, the points are (16, 292)

The slope of the linear equation is represented by $9.50

Hence, M = 9.5(16, 292)

Standard linear equation is given by

m = Mx + b … (1)

Substitute the values in the equation to get the values of b

292 = 9.5(16) + b

⇒ b = 292 - 152

⇒ b = 140

Substitute the values in the equation (1) again to get linear equation

⇒ m = 9.50h + 140

There are 4 liters of solution are needed for the 10% acid solution.

Unitary method:

Unitary method is the way to find the value of a single unit and then multiply the value of a single unit to the number of units to get the necessary value.

Given,

In a chemistry class, 8 liters of a 4% acid solution must be mixed with a 10% acid solution to get a 6% acid solution.

Here we need to find how many liters of the 10% acid solution are needed.

First, we have to convert the percentage into decimal,

4% = 4/100 = 0.04

10% = 10/100 = 0.10

6% = 6/100 = 0.06

Let x be the required liter of solution.

So, based in the given details,

We have to write the equation as,

=> 0.04*8 + 0.10x = 0.06(8+x)

=> 0.32 + 0.10x = 0.48 + 0.06x

=> 0.10x - 0.06x = 0.48 - 0.32

=> 0.04x = 0.16

=> x = 0.16/0.04

=> x = 4

x = 4 liters of 10% solution is used.

Step-by-step explanation:

Given that:

Winner is paid :

Monthly pay while on tour = $5000

Pay per CD sold =. $2

A) Equation which relates total earning in terms of number of months 'm' while on tour and the number 'n' of CD's sold.

(Monthly pay * number of months) + (pay per CD * number of CD's)

Earning = 5000m + 2n

B) How much will the winner earn after the first month if 500 CDs are sold?

m = 1, n = 500

5000(1) + 2(500) = $6000

C) Suppose after the third month on tour the new recording artist has earned a total of $74 000. How many GDs were sold?

m = 3

74000 = 5000(3) + 2n

74000 = 15000 + 2n

74000 - 15000 = 2n

59000 = 2n

n = 59000 / 2

n = 29500 CD's

D) In Canada, a record album or CD achieves gold status once it seLls 50 000 units. How much will the artist make if the CD goes gold after 6 months of touring?

We have shown that for every ε > 0 and e>0, there exists a measurable subset A⊆E and N∈N such that (a) If n > N then |fn(x) - f(x)| < ε for all x∈A. (b) m(E - A) < ε/.

Given E is a measurable set with finite measure and {fn} be a sequence of measurable functions on E that converges point wise to f:

E → R.

We need to prove that for every e>0 and ε > 0, there exists a measurable subset A⊆E and N∈N such that:

(a) If n > N then |fn(x) - f(x)| < ε for all x∈A.

(b) m(E - A) < ε.

Let {< € E: |f(x) - f(x)| < ε}  be measurable, where ε > 0.

Therefore, {Em} = {x ∈ E: |f(x) - f(x)| < ε} is an increasing sequence of measurable sets since {fn} converges pointwise to f, {Em} is a sequence of measurable functions on E.

Since E is a measurable set with finite measure, there exists a measurable set A⊆E such that m(A - Em) < ε/\(2^n\).

Then we have m(A - E) < ε using continuity of measure.

Since Em is increasing, there exists an n∈N such that Em ⊆ A, whenever m(E - A) < ε/\(2^n\)

Now, if n > N, we have |fn(x) - f(x)| < ε for all x∈A.

Also, m(E - A) < ε/\(2^n\) < ε.

Thus, we have shown that for every ε > 0 and e>0, there exists a measurable subset A⊆E and N∈N such that

(a) If n > N then |fn(x) - f(x)| < ε for all x∈A.

(b) m(E - A) < ε

Answer:

m = 2/3

Step-by-step explanation:

Rewrite in slope-intercept form.

y = -3/2x + 7/2

Using the slope-intercept form, the slope is −3/2.

m = -3/2

The equation of a perpendicular line to y=−3/2x + 7/2 must have a slope that is the negative reciprocal of the original slope.

Answer:

\(\frac{2}{3}\)

Step-by-step explanation:

• First rewrite the original equation in the form y = mx + c ,

where m = gradient:

\(3x + 2y = 7\)

⇒ \(2y = -3x + 7\)

⇒ \(y = \frac{-3}{2}x + \frac{7}{2}\)

• From this equation, we can see that the gradient, m = \(\frac{-3}{2}\) .

The gradient of a line perpendicular to another line with gradient m,  = \(\frac{-1}{m}\).

∴ gradient of perpendicular = -1  ÷   \(\frac{-3}{2}\)

x = \(\frac{17}{5}\)

Step-by-step explanation:

(8x - 12) = (3x + 5) ← remove parenthesis

8x - 12 = 3x + 5 ( subtract 3x from both sides )

5x - 12 = 5 ( add 12 to both sides )

5x = 17 ( divide both sides by 5 )

x = \(\frac{17}{5}\)

or x = 3.4 ( in decimal form )

The  equation in terms of (c) is:

c = a - b

the equation in terms of (x) is:

x = (y - b)/m

15) To make (c) the subject of the equation, we need to isolate (c) on one side of the equation. The equation is not provided, so I will use a generic formula as an example:

a = b + c

To make (c) the subject of this equation, we need to isolate it on one side of the equation. We can do this by subtracting (b) from both sides of the equation:

a - b = b + c - b

Simplifying the right-hand side of the equation:

a - b = c

Therefore, the equation in terms of (c) is:

c = a - b

This means that if we know the values of (a) and (b), we can use this equation to calculate the value of (c).

16) To make (x) the subject of the equation, we need to isolate (x) on one side of the equation. Again, the equation is not provided, so I will use a generic formula as an example:

y = mx + b

To make (x) the subject of this equation, we need to isolate it on one side of the equation. We can do this by subtracting (b) from both sides of the equation:

y - b = mx + b - b

Simplifying the right-hand side of the equation:

y - b = mx

To isolate (x), we need to divide both sides of the equation by (m):

(y - b)/m = (mx)/m

Simplifying the right-hand side of the equation:

(y - b)/m = x

Therefore, the equation in terms of (x) is:

x = (y - b)/m

This means that if we know the values of (y) and (m) and the y-intercept (b), we can use this equation to calculate the value of (x). This is a commonly used formula in algebra and is used to calculate the value of the independent variable (x) in a linear equation.

If Wendy spent $24.10 on 13 fries and burgers, then she bought 6 burgers and 7 orders of fries.

Let x be the number of burgers Wendy bought and y be the number of fries she bought.

We know that burgers cost $2.50 each and fries cost $1.30 each.

So the total cost of x burgers and y fries is:

2.5x + 1.3y

We also know that Wendy spent $24.10 on 13 burgers and fries, so:

2.5x + 1.3y = 24.10

Finally, we know that Wendy bought a total of 13 burgers and fries:

x + y = 13

Now we have two equations with two variables, which we can solve using substitution or elimination.

Let's use substitution:

x = 13 - y

Substitute this into the first equation:

2.5(13 - y) + 1.3y = 24.10

Simplify and solve for y:

32.5 - 2.5y + 1.3y = 24.10

-1.2y = -8.4

y = 7

So Wendy bought 7 orders of fries.

Substitute y = 7 into x + y = 13 to find x:

x + 7 = 13

x = 6

So Wendy bought 6 burgers and 7 orders of fries.

The best response functions for Player 1 and Player 2 are x = y/2 and y = -1/2, respectively. The rational reaction sets are given by x = y/2 and y = -1/2. The Nash equilibrium is x = y/2 = -1/4.

To find the best response functions, we need to determine the strategy that maximizes the payoff for each player given the other player's strategy. For Player 1, the best response function can be obtained by maximizing U1(x, y) = xy - x^2 with respect to x. Taking the derivative and setting it to zero, we find that the best response function for Player 1 is x = y/2.

Similarly, for Player 2, the best response function can be obtained by maximizing U2(x, y) = x + yy with respect to y. Taking the derivative and setting it to zero, we find that the best response function for Player 2 is y = -1/2.

The rational reaction sets for each player represent the set of strategies that maximize their payoffs given the other player's strategy. For Player 1, the rational reaction set is a line given by x = y/2. For Player 2, the rational reaction set is a single point, y = -1/2.

To find the Nash equilibria, we need to identify the combinations of strategies where both players are playing their best responses to each other. In this case, the Nash equilibrium occurs when both x and y satisfy the best response functions simultaneously. Substituting the best response functions into each other, we find that the Nash equilibrium is x = y/2 = -1/4.

In summary, the best response functions for Player 1 and Player 2 are x = y/2 and y = -1/2, respectively. The rational reaction sets are given by x = y/2 and y = -1/2. The Nash equilibrium is x = y/2 = -1/4. These results provide insights into the optimal strategies for each player and the stable outcomes of the game.
