Answer:

a. The number of different combinations of 2 components that can be chosen from a group of 12 is given by the formula:

nC2 = (n!)/(2!(n-2)!), where n is the total number of components

Substituting n = 12, we get:

nC2 = (12!)/(2!(12-2)!) = (12 x 11)/2 = 66

Therefore, there are 66 different combinations of 2 components that can be chosen from the group of 12.

b. The probability that the faulty component will be chosen for testing depends on the number of ways in which the faulty component can be chosen, and the total number of ways in which any 2 components can be chosen.

The probability of choosing the faulty component on the first pick is 1/12, as there is one faulty component out of a total of 12 components.

After the first component has been picked, there will be 11 components left, including one faulty component. Therefore, the probability of picking the faulty component on the second pick, given that the first pick did not pick the faulty component, is 1/11.

Therefore, the probability of picking the faulty component on either the first or second pick is:

P(faulty component) = P(faulty on first pick) + P(faulty on second pick, given not picked on first pick)

P(faulty component) = (1/12) + ((11/12) x (1/11))

P(faulty component) = 1/12 + 1/12

P(faulty component) = 1/6

Therefore, the probability of choosing the faulty component for testing is 1/6 or approximately 0.1667.

this is a rational number, since it can be written in fraction form, however it is not an integer because it is a decimal number and not a whole number.

====================================================

Explanation:

Pick any two numbers you want as long as they don't divide to form an integer. For instance, picking 14 and 7 divides to 14/7 = 2 which is an integer. So this pair of values won't work.

In this case, 2 and 3 don't divide to form an integer. We can see this through using a calculator

2/3 = 0.667 approximately

Note: The denominator can never be zero. The numerator can be zero, but a zero numerator leads to an integer, so you'll have to ignore zero entirely for this problem.

Answer:

the relationship between grams and micrograms is that one gram is equal to one million micrograms.

Step-by-step explanation:

The metric relationship between grams (g) and micrograms can be expressed as:

1 μg = 0.000001 g

The metric relationship between grams (g) and micrograms (μg) is based on the metric system's decimal-based prefixes.

In the metric system, "micro" is the prefix denoting a factor of 10⁻⁶, which means that one microgram is equal to one-millionth of a gram. This relationship can be expressed as:

1 μg = 0.000001 g

To convert from micrograms to grams, you divide the value in micrograms by one million. For example, if you have 500,000 micrograms, you divide it by one million to obtain the equivalent value in grams, which is 0.5 g.

Similarly, to convert from grams to micrograms, you multiply the value in grams by one million. For instance, if you have 0.75 g, you multiply it by one million to get the equivalent value in micrograms, which is 750,000 μg.

The metric system's use of prefixes allows for easy conversions between units by simply shifting the decimal point. This flexibility and simplicity make the metric system advantageous in scientific and everyday applications.

Answer:

Given: Two Isosceles triangle ABC and Δ PBC having same base BC. AD is the median of Δ ABC and PD is the median of Δ PBC.

To prove: Point A,D,P are collinear.

Proof:

→Case 1.  When vertices A and P are opposite side of Base BC.

In Δ ABD and Δ ACD

AB= AC   [Given]

AD is common.

BD=DC  [median of a triangle divides the side in two equal parts]

Δ ABD ≅Δ ACD [SSS]

∠1=∠2 [CPCT].........................(1)

Similarly, Δ PBD ≅ Δ PCD [By SSS]

∠ 3 = ∠4 [CPCT].................(2)

But,  ∠1+∠2+ ∠ 3 + ∠4 =360° [At a point angle formed is 360°]

2 ∠2 + 2∠ 4=360° [using (1) and (2)]

∠2 + ∠ 4=180°

But ,∠2 and ∠ 4 forms a linear pair i.e Point D is common point of intersection of median AD and PD of ΔABC and ΔPBC respectively.

So, point A, D, P lies on a line.

CASE 2.

When ΔABC and ΔPBC lie on same side of Base BC.

In ΔPBD and ΔPCD

PB=PC[given]

PD is common.

BD =DC [Median of a triangle divides the side in two equal parts]

ΔPBD ≅ ΔPCD  [SSS]

∠PDB=∠PDC [CPCT]

Similarly, By proving ΔADB≅ΔADC we will get,  ∠ADB=∠ADC[CPCT]

As PD and AD are medians to same base BC of ΔPBC and ΔABC.

∴ P,A,D lie on a line i.e they are collinear.

Answer:

Step-by-step explanation:

For the sake of the problem, let's make female workers "x" and male workers "y".

x+y<40       This equation shows that the total number of workers has a max of 40.

30x+20y<1,000      This equation shows that the total cost the manager pays ($30 to each woman, $20 to each man) has a max of $1,000.  

Now you can solve for x and y.

X+y<40

-y       -y

X<-y+40

Substitute -y+40 in for X in the second equation

30(-y+40)+20y<1,000      

-30y+1200+20y<1,000         Distribute

-10y+1,200<1,000      Combine like terms

-10y<-200                   Subtract 1,200

y>20                Divide by -10; flip the sign

Answer:

h(x) = 9x-18 is the correct inverse function

Step-by-step explanation:

f(x) -> y (first we need to rewrite the equation with y)

y= 1/9x+2 (next we need to solve for x)

y=1/9x

-2 -2  (subtract 2 from both sides)

y-2= 1/9x (multiply 9 on both sides

9y-18= x (and lastly switch back x and y)

y = 9x - 18 (if a real equation than write h(x) or \(f(x)^{-1}\), if not real equation keep it in y)

Let the position of the submarine be represented with X

Given

\(AB = 1425\)

\(\angle A = 59^{\circ}\)

\(\angle B = 47^{\circ}\)

First, we calculate angle at X.

\(\angle X + \angle A + \angle B = 180\)

\(\angle X + 59^{\circ} + 47^{\circ}= 180^{\circ}\)

\(\angle X = 180^{\circ} -59^{\circ} - 47^{\circ}\)

\(\angle X = 74^{\circ}\)

Solving (a): Distance AX: The distance between ship A and the submarine

To do this, we apply sine formula which states

\(\frac{a}{sin\ A} = \frac{b}{sin\ B} = \frac{c}{sin\ C}\)

In this case:

\(\frac{AB}{sin\ X} = \frac{AX}{sin\ B}\)

Substitute values for AB, \(\angle X\) and \(\angle B\)

\(\frac{1425}{sin(74^{\circ})} = \frac{AX}{sin(47^{\circ})}\)

Make AX the subject

\(AX = \frac{1425}{sin(74^{\circ})} * sin(47^{\circ})\)

\(AX = \frac{1425}{0.9613} * 0.7314\)

\(AX = \frac{1425 * 0.7314}{0.9613}\)

\(AX = \frac{1042.245}{0.9613}\)

\(AX = 1084.20\)

Solving (b): Distance BX: The distance between ship B and the submarine

To do this, we apply sine formula which states

In this case:

\(\frac{AB}{sin\ X} = \frac{BX}{sin\ A}\)

Substitute values for AB, \(\angle X\) and \(\angle A\)

\(\frac{1425}{sin(74^{\circ})} = \frac{BX}{sin(59^{\circ})}\)

Make BX the subject

\(BX = \frac{1425}{sin(74^{\circ})} * sin(59^{\circ})\)

\(BX = \frac{1425}{0.9613} * 0.8572\)

\(BX = \frac{1425* 0.8572}{0.9613}\)

\(BX = \frac{1221.51}{0.9613}\)

A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

a)

Let the fraction be represented as A

Now , After first journey the amount of fuel left was = 1 - ( 7/16 )

On simplifying the equation , we get

The amount of fuel left = 9/16

( 1/3 ) of the fuel was used , so 2/3 of the fuel is left in the tank

Substituting the values in the equation , we get

The amount of fuel left in the tank A = ( 2/3 ) of ( 9/16 )

The amount of fuel left in the tank A = 3/8

The value of the radius of the pulley was r = 0.01 m, the experimental moment of inertia of the plate is 1.98 x 10^-4 kg m². This is option A

The moment of inertia of a rigid body is a physical quantity that indicates how resistant it is to rotational acceleration around an axis of rotation. Inertia is the term for a property of a body that makes it oppose any force that seeks to modify its motion. The body would be difficult to set into motion or halt if it has a high moment of inertia.

The formula for the moment of inertia is given below:

I = m * r²

where, I is the moment of inertia, m is the mass, and r is the distance from the axis of rotation to the center of mass.

The following is the procedure for calculating the moment of inertia of the plate from the angular velocity versus time graph:

Find the slope of the linear part of the graph to calculate the angular acceleration by the formula α = slope.Substitute the values into the formula τ = Iα to calculate the torque acting on the plate.

Substitute the values into the formula τ = F * r to determine the force acting on the plate.The weight of the hanging mass is converted to force F by the formula F = mg.

Substitute the values into the formula I = m * r²/α to obtain the moment of inertia.

I = m * r²/αI = (0.050 kg) * (0.01 m)²/ (5.5 rad/s²)

I = 1.98 x 10^-4 kg m²

Hence, the experimental moment of inertia of the plate is 1.98 x 10^-4 kg m².

So, the correct answer is A
