A coffee shop sells coffee to about 500 people every morning, but this can vary by as many as 60 people. On any given day, what are the maximum and minimum numbers of people expected to buy coffee?

Answer:

(8,-43)

(4,-22)

Step-by-step explanation:

In order for the ordered pair to be a solution of the inequality, you must be able to plug in the y-value of the ordered pair and it must be less than or equal to 0.

For example:

(4,-22)

x=4 ; y=-22

Plug y into the inequality

y≤0

-22≤0

Since the statement is true, I know that (4,-22) must be a solution to the inequality.

Another way to solve this problem is by graphing. If an ordered pair is in the shaded region, it is a solution to the inequality. Attached is a graph of both the inequality and ordered pairs plotted.

Answer:

Step-by-step explanation:

To determine whether each ordered pair is a solution to the inequality y ≤ 0, we need to check if the y-coordinate of each pair is less than or equal to zero.

Let's check each ordered pair:

(8, -43):

The y-coordinate is -43. Since -43 is less than zero, this ordered pair is a solution to the inequality y ≤ 0.

(4, -22):

The y-coordinate is -22. Since -22 is less than zero, this ordered pair is a solution to the inequality y ≤ 0.

(-3, 25):

The y-coordinate is 25. Since 25 is greater than zero, this ordered pair is not a solution to the inequality y ≤ 0.

(-7, 45):

The y-coordinate is 45. Since 45 is greater than zero, this ordered pair is not a solution to the inequality y ≤ 0.

So, the solutions to the inequality y ≤ 0 are:

(8, -43) and (4, -22).

Answer:

$0.05 per oz.

Step-by-step explanation:

2.39/48=0.049...... which is 0.05 to the nearest tenth. Money is never the unit rate so that is why you divide money by the measurement, in this case, ounces.

The required probability that either event will occur is 22.

According to the given Venn diagram, we have:

P(A) = 9 + 3 = 12

P(B) = 3 + 10 = 13

P(A and B) = 3

The probability that either event will occur can be calculated as follows:

P(A or B) = P(A) + P(B) - P(A and B)

The formula operates by first summing the probabilities of the individual occurrences, but then removing the probability that both events will occur at the same time.

Substitute the given values in the above formula to get,

P(A or B) = 12 + 13 - 3

P(A or B) = 25 - 3

P(A or B) = 22

Therefore, the required probability that either event will occur is 22.

Step-by-step explanation:

The derivative is f'(x) = (4x - 1) / (2x² - x).

To find the derivative of the function f(x) = ln(2x² - x), we can use the chain rule.

Begin by identifying the function to be differentiated, which is f(x) = ln(2x² - x).

Apply the chain rule, which states that if we have a composition of functions, f(g(x)), the derivative is given by (f'(g(x))) g'(x).

Let's consider the inner function g(x) = 2x² - x.

To differentiate g(x), we need to apply the power rule and the constant rule. The derivative of 2x² is 4x, and the derivative of -x is -1.

Now, we differentiate the outer function f'(g(x)). The derivative of ln(x) is 1/x.

Finally, we multiply the derivatives obtained in steps 3 and 4. Thus, the derivative of f(x) = ln(2x² - x) is:

f'(x) = (1 / (2x² - x)) * (4x - 1)

Simplifying further, we have:

f'(x) = (4x - 1) / (2x² - x)

Answer:

Third block is the biggest,

Step-by-step explanation:

Since size of a block is a three dimensional property and decided by the volume.

Formula of the volume of a prism of block is,

V = Length × width × height

Volume of block (1) = 1 × 1 × 7 = 7 m³

Volume of block (2) = 5 × 5 × 1 = 25 m³

Volume of block (3) = 3 × 3 × 3 = 27 m³

This reveals, volume of block (3) is maximum and volume of block (1) is the least.

Therefore. \(V_3>V_2>V_1\) is the decreasing order of the volumes of the given blocks.

Third block is the biggest of all three.

Answer: 4410 \(ft^2\)

Step-by-step explanation:

To find the area of a square or rectangle, all you need to do is multiply the length times the width:

L × W = A

The lengh is 100, and the width is 50

100 × 50 = 5000

However, in this problem, we also have other shapes in the rectangle. To find the area of JUST the green, we need to subtract the areas of the two circles and small blue rectangle.

First, let's get the two circles over with. To find the area of a circle, use this formula:

A = π\(r^2\)      r is the radius, which in this case, is 6

A = π\(6^2\)

A = 113       This isn't the exact answer, the exact answer would be 113.0973...

Now let's multiply the area of one of those circles by 2, since we have 2 circles:

113 × 2 = 226

Finally, we have to find the area of the blue rectangle. This is simple, just use the formula from the very beginning:

26 × 14 = 364

The last thing to do is to subtract the areas of the two circles and blue rectangle from the area of the entire thing:

5000 - (226 + 364) = 4410 \(ft^2\)

Step-by-step explanation:

2{[2(14-x)]-x} = 0  Distribute the 2

2[28-2x -x) -x = 0  Combine like terms

2(28 -3x) -x = 0   Distribute the 2

56 - 6x - x= 0  Combine like terms

56 -7x = 0  Subtract 56 from both sides

-7x  = -56   Divide both sides by -7

x = 8

Check:

7 x 2 = 14

14 - 8 = 6

6 x 2 = 12

12 - 8 = 4

4 x 2 = 8

Answer:

A. \(n=100\)
B. \(k=0\)

Step-by-step explanation:

A. The equation "110% n = 11" can be solved as follows:

110% n = 11

To solve for n, we need to get rid of the percentage sign (%). We can do this by dividing both sides of the equation by 110%, or 0.110 (since 110% is equivalent to 1.1 in decimal form).

(110% n) / 110% = 11 / 110%

n = 11 / 0.110

n = 100

So, the solution for n in the equation "110% n = 11" is n = 100.

B. The given equation is:

(328 x 128) x k = 328 x (82 x 128) x k

To solve for k, we can simplify the equation using the properties of multiplication.

Step 1: Perform the multiplications inside the parentheses:

41984 x k = 328 x 10576 x k

Step 2: Rearrange the equation by applying the associative property of multiplication:

41984 x k = 328 x (10576 x k)

Step 3: Divide both sides of the equation by 328:

(41984 x k) / 328 = 10576 x k

Step 4: Cancel out the common factor of k on the left-hand side:

(41984 / 328) x k = 10576 x k

Step 5: Simplify the left-hand side:

128 x k = 10576 x k

Step 6: Subtract 10576 x k from both sides of the equation to isolate k:

128 x k - 10576 x k = 0

Step 7: Factor out k on the left-hand side:

k x (128 - 10576) = 0

Step 8: Simplify further:

k x (-10448) = 0

Step 9: Divide both sides of the equation by (-10448):

k = 0

So, the solution for k in the equation "(328 x 128) x k = 328 x (82 x 128) x k" is k = 0.

The product of roots with the same index is equal to the root of the product \(3\sqrt{11*2}\)

Multiply

\(\sf\sin^2 150^\circ + \sin^2 60^\circ = 1 \\\)

Step 1: Convert degrees to radians:

\(\sf\sin^2 \left(\frac{150\pi}{180}\right) + \sin^2 \left(\frac{60\pi}{180}\right) = 1 \\\)

Step 2: Simplify the expressions using the trigonometric identity:

\(\sf\sin^2 \left(\frac{\pi}{6}\right) + \sin^2 \left(\frac{\pi}{3}\right) = 1 \\\)

Step 3: Recall the values of sine for angles \(\sf \frac{\pi}{6} \\\) and \(\sf \frac{\pi}{3} \\\):

\(\sf\left(\frac{1}{2}\right)^2 + \left(\frac{\sqrt{3}}{2}\right)^2 = 1 \\\)

Step 4: Evaluate the squares and simplify further:

\(\sf\frac{1}{4} + \frac{3}{4} = 1 \\\)

Step 5: Combine the fractions:

\(\sf\frac{4}{4} = 1 \\\)

Step 6: Simplify the fraction:

\(\sf1 = 1 \\\)

Thus, the equation \(\sf \sin^2 150^\circ + \sin^2 60^\circ = 1 \\\) is verified and true.
