What is addition method?

Using the Addition Method to Solve Systems of Equations in Two Variables. The addition approach, often known as the elimination method, is a third strategy for resolving linear equation systems. With this approach, we combine two components that share the same variable but have opposing coefficients, resulting in a sum of zero.

Let,  money is invested at two rates of interest.

One rate is 8% and the other is 2%.

There is $800 more invested at 8 % than at 2 %.

Total annual interest received is $490.

Let x = amount invested at 8 % and

y = amount invested at 2 %.

So,

x - y = 800                    ..(1)

0.08x + 0.02y = 490        ..(2)

Multiply equation (1) by -8 and equation (2) by 100

-8x + 8y = -6400            ..(3)

8x + 2y = 49000           ..(4)

Adding equation (3) and (4)

(-8x + 8y) + (8x + 2y) = -6400 + 49000

                           10y = 42600

                               y = 4260

Plug y = 4260 in equation (1)

x - 4260 = 800

           x = 800 + 4260

           x = 5060

Hence, amount invested at 8% = $5060.

amount invested at 2% = $4260.

The equation of the line having equal intercepts on the axes is:

13x+13y=6.

Given:

the straight lines are:

4x-7y-3 and 2x-3y+1

we are asked to determine the equation of the straight line passing through the point of intersection of the lines 4x-7y-3 and 2x-3y+1 and cut with the equal intercept on the axes.

Let the equation of the line having equal intercepts on the axes be

x/a + y/a =1

x + y = a ... eq(1)

On solving equation 4x-7y-3 and 2x-3y+1 we obtain x = 1/13 and y = 5/13.

{1/13,5/13} is the point of intersection of the two given lines.

Since equation (1) passes through point {1/13,5/13}

{1/13+5/13} = a

⇒ a = 6/13

∴ Equation (1) becomes x+y=6/13

⇒ 13x+13y=6

The probability that the mean time for the sample of 150 returns for this year is greater than 92 is 0.95907

Given,

Mean, [tex]\overline x[/tex] = 90 minutes

standard deviation, [tex]\sigma[/tex] = 14 minutes

to find probability that mean for sample 150 returns is greater than 92, [tex]P(\overline x > 92)[/tex]

This means we need to find probability the related z-value of expected mean

where, [tex]z=\frac{\overline x-\mu_x}{\sigma_x}[/tex]

Here,

[tex]\mu_x[/tex]= expected mean =92

[tex]\sigma_x[/tex]=standard deviation for new sample i.e. 150

[tex]\sigma_x[/tex] can be calculated by formula,

[tex]\sigma_x=\frac{\sigma}{\sqrt{n}}\\\\\sigma_x=\frac{14}{\sqrt{150}}\\\\\sigma_x=1.143[/tex]

Now,

[tex]z=\frac{90-92}{1.143}\\\\z=-1.749[/tex]

Now,

[tex]P(\overline x > 92)\\\\=P(z > -1.749)\\\\=1-P(z < -1.749)\\\\=1-0.04093\\\\=0.95907[/tex]

6. calculate the leaving time of previous stations.

7. Finally, we need two tables to store the partial results that are calculated for each station in an assembly line.

Example:- a = [[5,4,3], [2,3,7]], t = [[0,2,2], [0,1,1]]

e1 = 3, e2 = 2

x1 = 3, x2 = 4

T1[0] = e1 + a[0][0] = 3+5 = 8

T1 = [8, 0, 0]

T2 = [4, 0, 0]

i = 1

T1[1] = min(T1[1-1] + a[0][1], T2[1-1] + t[1][1] + a[0][1])

= min(8+4, 4+1+4) = min(12,9)

T1[1] = 9

T2[1] = min(T2[1-1] + a[1][1], T1[1-1] + t[0][1] + a[1][1])

T1[2] = 11

T2[2] = min(T2[2-1] + a[1][2], T1[2-1] + t[0][2] + a[1][2])

Sand is leaving at the rate of 3528 cm³/s when Sand collects in a conical pile with a radius that is always three times.

Given that,

Sand collects in a conical pile with a radius that is always three times its height as it falls from an overhead container. When the pile is 14 cm high, assume that the height of the pile is growing at a rate of 2 cm/s.

We have to find how quickly is the sand currently leaving the bin. Let V and h represent the cone's volume and height, respectively. Create an equation that connects V and h but leaves out the cone's radius.

We know that,

From given  r = 3 × h

Get an equation for the cone's volume in terms of height first.

v = 1/3 × π × r² × h

v = 1/3 × π × (3 × h)² × h

v = 1/3 × π × 9 × h³

Take derivative of both sides

d/dt { v = 3 × π × h }

dv/dt = 9 × pi × h² × dh/dt

In your problem,

dh/dt =2cm/sd

h = 14 cm

Plug in and solve for dh/dt

dv/dt = 9× π × 196 m² × 2

dv/dt = 3528 π cm³/s

The difference between 2X₁ and  X₁+X₂ is N(0,6σ²)

According to the Central Limit Theorem, any large sum of the independent, identically distributed(iid) random variables is approximately Normal.

We know very well that the Normal distribution is defined by two parameters, the mean is μ , and the variance is σ²  and written as X=N(μ,σ²).

Using the  properties of normal random variables, we get

if  X=N(μ₁,σ₁²)and Y=N(μ₁,σ₁²) are two independent identically distributed random variables then

the sum of normal random variables is represented by

=>X+Y=N(μ₁+u₂,σ₁²+σ₂²)

and the difference of normal random variables is represented by

=>X-Y =N( μ₁-u₂,σ₁²+σ₂²)  

When  Z=aX+bY, the linear combination of X and Y is given by

=>Z=N(aμ₁+bu₂,a²σ₁²+b²σ₂²)

Similarly, When Z=aX , the product of X is given by

=>Z=  N(aμ₁,a²σ₁²)

We need to find 2X₁

Thus, following the property of multiplication, we get

=>2X₁=N(2μ,2²σ²)

=>2X₁=N(2μ,4σ²)

and following the property of addition,

X₁+X₂=N(μ+μ,σ²+σ²)

And the difference between the two is given by

2X₁-(X₁+X₂)=N(2μ-2μ,2σ₁²+4σ₂²)

=>2X₁-(X₁+X₂)=N(0,6σ²)

Hence, the required difference is N(0,6σ²).

Using Combination formula,

Total 5,110 ways are possible that the coin land tails either exactly 9 times or exactly 2 times

Combinations:

If the order of events is not important, the concept of combination determines the number of ways in which a sequence of events can be obtained. I need to find the total number of expected events and the total number of possible events.

We have given that,

A unbiased or fair coin is tossed 15 times.

let us consider two events

A : the coin land tails exactly 9 times

B : the coin land tails exactly 2 times

Now, for calculating the required result we use

Combination formula,

ⁿCₓ= n! /x! (n-x)!

here, n= 15

the number of ways that exactly 9 times coin land as tails (n(A))= ¹⁵C₉ = 15! /9!× 6!

= 15×14×13×12×11×10×9!/ 9!(6×5×4×3×2×1)

= (15×14×13×12×11×10)/( 6×5×4×3×2×1 )

= (15×14×13×11)/6 = 7× 5× 13×11 = 5005

the number of ways that exactly 2 times coin land as tails (n(B))= ¹⁵C₂= 15! /2!× 13!

= 15×14×13!/13!(2)

= 15×14/2 = 15×7 = 105

Now, the number of ways that the coin land tails either exactly 9 times or exactly 2 times

= n(A) + n(B) = 5005 + 105

The temperature equation is T(x) = 180 - 2.25*x, using that we will see:

A) after 20 minutes the temperature is 135

B) the temperature will be 100 after 35.56 minutes.

We know that the initial temperature is 180°F and it changes at a rate of -2.25°F per minute, so after x minutes, the temperature is:

T(x) = 180 - 2.25*x

A) after 20 minutes, the temperature is:

T(20) = 180 - 2.25*20 = 135

The temperature after 20 minutes is 135

B) How long will it take to go from 180°F to 100°F?

We need to solve the equation:

T(x) = 100

180 - 2.25*x = 100

180 - 100 = 2.25*x

80/2.25 = x

The margin of error is computed using the standard deviation.

The term "standard deviation" reveals that a measurement of the data's dispersion from the mean. While a high standard deviation indicates that the data are more spread or dispersed, a low standard deviation suggests that the data are clustered or gathered around the mean.

It depicts the average deviation of each score from the mean. A high standard deviation in a normal distribution denotes that values are often far from the mean, while a low standard deviation denotes that values are grouped together around the mean.
