A company has 14 employees at the cental, 8 employees at the north and 6 employees at the south. They want to lay off 12 employees. In how many ways can this be done?

the relative rate of change of each species in the reaction can be determined using stoichiometry.

The stoichiometry of the reaction tells us that for every 3 moles of species A consumed, 2 moles of species C are produced. Therefore, the relative rate of change of species A can be calculated by multiplying the rate of the reaction (0.420 m/s) by the stoichiometric coefficient of A (-3), and dividing by the stoichiometric coefficient of C (2). Similarly, the relative rate of change of species B can be calculated by multiplying the rate of the reaction by the stoichiometric coefficient of B (-1) and dividing by the stoichiometric coefficient of C (2). The relative rate of change of species C is simply equal to the rate of the reaction.

the relative rate of change of each species in the reaction can be determined by applying stoichiometry. The relative rate of change of species A is (-0.630 m/s), the relative rate of change of species B is (-0.210 m/s), and the relative rate of change of species C is (0.420 m/s).

25 is the answer.

Step-by-step explanation:

Answer:

25 because 7 squared plus 24 squared is 625 then you find the square root which is 25.

The chance of the event B is 0.4 when using the probability for the two independent two event formula.

In the given question, if a and b are independent events with p(a) = 0.65 and p(a ∩ b) = 0.26, then we have to find the value of p(b).

Events classified as independent do not depend on other events for their occurrence.

Event A's likelihood of happening is P(A)=0.65.

The likelihood of the two events A and B intersecting is P(A∩B)=0.26.

Given that the likelihood of the two independent events is:

P(A∩B) = P(A)⋅P(B)

Then the probability of the event B will be,

P(B) = P(A)/P(A∩B)

P(B) = 0.65/0.26

P(B) =0.4

Answer:

Let be the number of times that Sam scored 3 points. If ≤ 4 then his maximum score would be 3 × 4 + 6 = 18 which is too small. If ≥ 7 then his minimum score would be 3 × 7 = 21 which is too big. Hence is either 5 or 6.

Suppose = 6. So Sam had 6 words not shared with the other boys, giving him 18 points. To get a score of 19, he must have shared one word with one other boy and picked three words shared with them both. That means that the other two boys also scored 0 points for those three words. To score more than 19 they must have scored 3 points for each of their 7 remaining words. However one of them has shared a word with Sam so scored a maximum of 19 points. Hence ≠ 6.

Hence = 5, giving Sam 15 points for these 5 words. To score 19, Sam must have scored 1 point for another four words and there must have been one word shared by all three boys. Each of the other two must have scored 3 points at least 6 times in order to score more than Sam. Also each scored 0 points for one word. That determines the scores for seven of each boy’s words. Between the two, they shared a word with Sam 4 times; and these could be divided between them either 2 each or 1 and 3. The former case leaves only one word each to fix and this could be either 1 point each or 3 points each. But that would give the two boys the same score. Therefore one boy had 3 words shared with Sam and so a score of 21. The other had only one word shared with Sam and the remaining two words must have scored 3 points, giving a total of 25. So James scored 25 points.

Step-by-step explanation:

In the picture attached, the Venn diagram is shown

amount of ASE certified brakes mechanics: 4+2+2+1 = 9

amount of mechanics: 4+2+2+1+3+3+3 = 18

The probability that a randomly selected mechanic is ASE certified to work on brakes: 9/18 = 1/2

The following equation is m=d-10+k×i represent the total amount in account(m) in dollar.

Although the question does not specify the options, but I have specified my answer as follows:

Given:

The equation representing the total amount in the account, m, when starting with d dollars and being charged a 10$ fee.

Account Opening Charges: $10

Starting amount: $d

The total amount in the account: $m

Let us say the depositor deposits an amount $k for 'i' number of months

Banks deduct their charges from the account balance itself, hence account opening charges are deducted from the bank balance.

I have assumed an amount $k invested every month. You can remove that term as per the requirement of the question.

The total amount at a point in time = starting amount - Account Opening Charges + monthly deposit till that time

⇒m=d-10+k×i

This equation shows that the total amount in the account will be equal to the initial deposit minus the fee charged by the bank.

Therefore, the following equation is m=d-10+k×i.

Let x = the number

2(x+5)=20

  x+5=10

      x=5

Answer:

x = 5

Step-by-step explanation:

Let the unknown number be x

\(2(x + 5) = 20\)

Expand

\(2(x + 5) = 2x + 10 \\ 2x + 10 = 20\)

Collect like terms and simplify

\(2x = 20 - 10 \\ 2x = 10\)

Divide both sides of the equation by 2

\( \frac{2x}{ 2} = \frac{10}{2} \\ x = 5\)

If we want to find the area of the shaded region, we would have to find the area of the circle and the area of the triangles, and subtract the last result from the area of the big shape.

Area of the circle

Using the formula for the area of the circle, we have:

Area of the triangles:

Angle θ is equal to 360° divided by 8 given that we have 8 equal parts. Angle θ =45.

We are going to find the area of each triangle with the formula A=(1/2)(a)(b)(sin(C). In this case a=10 cm ,b=10 cm and sin(C)=sin(45)=0.707.

Replacing in the formula, we have:

The area of the 8 triangles is: 35.35 x 8 cm^2 = 282.8 cm^2 (Multiplying)

Area of the shaded region

Area of the circle - Area of the triangles = 314 cm^2 - 282.8 cm^2 = 31.2 cm^2

The answer is 31.2 cm^2 rounded to three significant figures.

What is parallelogram?

It is a special type of quadrilateral that has both the pairs of opposite sides parallel and equal.

What is the area of parallelogram?

The area of a parallelogram is the product of its base and height.

We have,

length of two adjacent sides are 70meters and 100meters.

And base of parallelogram is 70m.      (length of parallelogram is its base)

Angle between the adjacent sides is 70 degrees.

Let, side AB and BC be the two adjacent sides whose lengths are 70m and 100m.And h be the height of the parallelogram.

For the height of the parallelogram

In ΔADE, we have

\(sin70=\frac{DE}{AD}\)           \((sinx=\frac{perpendicular}{hypotenuse})\)

⇒ \(0.9397=\frac{h}{70}\)

⇒ \(0.9397\)×70\(=h\)

⇒ h=65.8m

Formula to find the area of parallelogram:

Area= base× height

so, the area of parking lot=base × height

substitute the value of base and height of the parallelogram in the above formula.

Therefore,

\(Area=65.8\)×\(70\)

\(Area=4606m^{2}\)

Hence, the area of the parking lot is 4606 square meter.

Trigonometric ratios for a right angled triangle are from the perspective of a particular non-right angle.

In a right angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slant side is called hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called base.

From that angle (suppose its measure is θ),

\(\sin(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of Hypotenuse}}\\\cos(\theta) = \dfrac{\text{Length of Base }}{\text{Length of Hypotenuse}}\\\\\tan(\theta) = \dfrac{\text{Length of perpendicular}}{\text{Length of base}}\\\\\cot(\theta) = \dfrac{\text{Length of base}}{\text{Length of perpendicular}}\\\\\sec(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of base}}\\\\\csc(\theta) = \dfrac{\text{Length of Hypotenuse}}{\text{Length of perpendicular}}\\\)

First, let's calculate the store's selling price after marking up the swing set by 180%:

Selling price = Cost price + Mark up

Selling price = $90 + (180% of $90)

Selling price = $90 + $162

Selling price = $252

So the store's selling price for the swing set was $252.

Next, the store marked it down by 50%, which means the new selling price is:

New selling price = Selling price - (50% of Selling price)

New selling price = $252 - (50% of $252)

New selling price = $252 - $126

New selling price = $126

Therefore, the final discount price of the swing set is $126.
