15 ounces of herbs should be mixed to produce a mixture of costing $2.50 per ounce.

What is meant by addition?

In mathematics, addition is the process of fusing two or more integers. The numbers being added are known as addends, while the outcome of the addition process, or the final response, is known as the sum. It is one of the fundamental mathematical operations we employ on a daily basis. We add numbers in many different contexts.

Given that, an herbalist has 15 ounces of herbs costing $3 per ounce.

Let the ounces of herbs costing $2 per ounce that should be added to the above herbs be 'x'

Cost of total mixture is 15*3 + x*2 = (x+15)*2.5

15*(3-2.5) = x*(2.5-2)

15*0.5 = x*0.5

x = 15

Therefore, 15 oz of herbs for $2 should be added.

Step-by-step explanation:

 strawberries to plums  9:1       then total would be 10 parts  of which 1 is plums    so    1 : 10

In the illustration given above, the length and the diameter of the shaft would be = 21.8 in and 7/8 in respectively.

The total length of the shaft can be calculated through the addition of the various given lengths along the shaft such as follows:

= 5⅛ + 5 + 7⅝ + 4 1/16

First convert all the mixed fraction into single fraction;

= 41/8 + 5/1 + 61/8 + 65/16

= 82+80+122+65/16

= 349/16

= 21.8 in.

The diameter of the shaft can be calculated as follows;

= 7¼ - (3 3/16 + 3 3/16 )

First convert all the mixed fraction into single fraction;

= 29/4 - (51/16 + 51/16)

= 29/4 - 102/16

= 116-102/16

= 14/16

Is that all of the question?

Answer:

  ±1.007%

Step-by-step explanation:

You want the relative error in the computed value of 1/P -1/Q when P=1.80 and Q=2.91.

Each of P and Q is specified to the hundredths place, so the errors in each of P and Q will be half of a hundredth, or 0.005. The maximum value of P or Q will be 0.005 more than the given value, and the minimum will be 0.005 less.

The maximum and minimum of the computation will be had when P and Q are at their opposite extremes: one is a maximum when the other is a minimum.

Max difference = 1/1.795 -1/2.915 ≈ 0.21404

Min difference = 1/1.805 -1/2.905 ≈ 0.20978

The relative error in the computed value can be found a couple of ways. One is to compare the maximum and minimum computed values with the nominal computed value.

Here, we choose to compare half the difference in the computed values to the average of the computed values. That way, we can describe the error as symmetrical about that average;

  ((0.21404 -0.20978)/2) / ((0.21404 +0.20978)/2) = relative error

  = (0.21404 -0.20978) / (0.21404 +0.20978) ≈ 0.01007

The relative error is about ±1.007%.

__

Additional comment

Another way to compute the error is by looking at the derivatives. The relative error found that way is ...

  RE = -∆P(Q/P(Q -P)) +∆Q(P/Q(Q -P))

where ∆P and ∆Q are ±0.005.

The maximum relative error found this way is about ±1.00686% compared to the ±1.00685% computed above.

If you compare the possible error to the nominal value, it is not symmetrical: -1.00532% to 1.00841%.

Looking at the above expression for RE, you see that the multiplier of the relative error in P is Q/(Q-P), while the multiplier of the relative error in Q is P/(Q-P). That is, errors in P have a much larger effect than errors in Q.

Newington's budget in the "previous year" is $119.2 million

The term "budget" refers to a financial plan for a given period that outlines expected expenses and revenues. The previous year's budget for Newington is the financial plan that the town had for the previous fiscal year.

Assuming the previous year's budget refers to the fiscal year that ended just before the current fiscal year, we can find the amount by looking at the town's financial statements for that period. These statements will show the town's revenues and expenses for that fiscal year, and the difference between the two will be the budget.

If the town had $100 million in revenues and $95 million in expenses in the previous fiscal year, then the budget for that year would be $5 million. This means that the proposed $124.2 million budget for the upcoming year is a 4.7% increase from the $119.2 million budget of the previous year.

Step-by-step explanation:

the zeros are the x-intercepts. because these are x values, when y (= f(x)) = 0.

a quadratic equation has 2 zeros (even if they are equal or complex numbers).

a quadratic equation

ax² + bx + c = 0

can always be solved by

x = (-b ± sqrt(b² - 4ac))/(2a)

in our case

x = (-14 ± sqrt(14² - 4×2×20))/(2×2) =

= (-14 ± sqrt(196 - 160))/4 =

= (-14 ± sqrt(36))/4 = (-14 ± 6)/4

x1 = (-14 + 6)/4 = -8/4 = -2

x2 = (-14 - 6)/4 = -20/4 = -5

these are the 2 zeros (x-intercepts).

if you need the explicit points :

The statement "the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring." is false.

What is meant by probability?

The probability of an occurrence is a figure that represents how likely it is that the event will take place. In terms of percentage notation, it is expressed as a number between 0 and 1, or between 0% and 100%. The higher the likelihood, the more likely it is that the event will take place.

The given statement is:

"the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring."

This is a false statement.

The probability of the union of two events is the probability of individual events without considering the probability of the intersection of the events.

When the events do not have an intersection, then the probability of a union of events is greater than the probability of an intersection of events.

The chance of both occurrences occurring together is given by the union of two events, but the probability of both events occurring simultaneously is given by the intersection of two events, which is smaller than probability of union of events.

Therefore the statement "the probability of the union of two events occurring can never be more than the probability of the intersection of two events occurring." is false.

There is no real solution to the given equation s = 4 + sqrt(s+2) with value of s = 2, s = 7, s = 2 or s = 7.

To solve the equation:

s = 4 + sqrt(s+2)

We can start by isolating the square root term on one side:

s - 4 = sqrt(s+2)

Then, we can square both sides to eliminate the square root:

(s - 4)^2 = s + 2

Expanding the left side:

s^2 - 8s + 16 = s + 2

Bringing all terms to one side:

s^2 - 9s + 14 = 0

We can solve for s using the quadratic formula:

s = (9 ± sqrt(9^2 - 4(1)(14))) / 2(1)

s = (9 ± sqrt(49)) / 2

s = (9 ± 7) / 2

So the two possible solutions are:

s = 8/2 = 4

s = 2/2 = 1

However, we need to check if these solutions satisfy the original equation.

If we plug s=4 into the equation, we get:

4 = 4 + sqrt(4+2)

4 = 4 + sqrt(6)

This is not true, since the right-hand side is greater than the left-hand side.

If we plug s=1 into the equation, we get:

1 = 4 + sqrt(1+2)

1 = 4 + sqrt(3)

This is also not true.

Therefore, there is no real solution to the equation s = 4 + sqrt(s+2).

Helena can paint approximately 32 of these cylinders complete

Step-by-step explanation:

The surface area of a cylinder can be found using the formula:

Surface Area = 2πr(r + h), where r is the radius and h is the height (or length) of the cylinder.

For a cylinder with a radius of 5 cm and a length of 3 cm, the surface area is:

Surface Area = 2π x 5 x (5 + 3) = 2π x 5 x 8 = 80π cm²

So, the surface area of one cylinder is 80π cm². To find the number of cylinders that Helena can paint, we can divide her total paint coverage by the surface area of one cylinder:

2500 cm² ÷ 80π cm² = 31.83 (approximately 32 cylinders).

So, Helena can paint approximately 32 of these cylinders completel

The algebraic expression G x C, where G represents the total number of gallons needed and C represents the cost per gallon.

In mathematics, an expression is a combination of one or more numbers, variables, and/or operators that represent a quantity or a mathematical relationship.

To calculate the total cost of gasoline, we first need to determine how many gallons of gasoline will be needed for the entire trip. This can be done by dividing the total distance traveled by the car's miles per gallon (MPG) rating. Let's use "G" to represent the total number of gallons needed.

G = Total Distance Traveled / MPG

To find the total cost of gasoline, we can multiply the number of gallons needed by the cost per gallon. Let's use "T" to represent the total cost of gasoline.

T = G x C

The measurement of the angle 1 in the given parallel lines is 35° whereas the value of x is 15.

Parallel lines are those straight lines that are always the same distance apart from each other.

Given that, two lines RS and TU are parallel, and ∠ 7 = 3x-10 and ∠ 3 = 2x+5,

We need to find ∠ 1

Since, ∠ 7 and ∠ 3 are corresponding angles between two parallel lines therefore, both are congruent,

Therefore,

3x-10 = 2x+5

x = 15

Now, ∠ 1 = ∠ 3 as they are vertically opposite angles,

Therefore,

∠ 1 = 2(15)+5

The measures of angle possible for of an isosceles triangle when one angle given is 140° then other two angles is 20°.

In an isosceles triangle, two of the angles have the same measure. Let's call this measure x. Since the sum of the angles of a triangle is 180 degrees, we can set up an equation:

x + x + 140° = 180°

Simplifying the equation, we get:

2x + 140° = 180°

Subtracting 140° from both sides, we get:

2x = 40°

Dividing both sides by 2, we get:

x = 20°

So the other two angles in the isosceles triangle each measure:

x = 20°
