Determine the values of a and b, so that the following system of linear equations have infinitely many solutions:
(2a−1)x+3y−5=0
3x+(b−1)y−2=0

A number which is subtracted by 3 from it first and the total then divided by 8, which results in 4 is 35

Let's the number we're trying to find be "x".

So, according to the problem, if we subtract 3 from x first, we get,

x - 3

Then, if we divide that total by 8, we get 4:

(x - 3) / 8 = 4

Now, we can solve for x by isolating it on one side of the equation. First, we can multiply both sides of the equation by 8:

x - 3 = 32

x = 35

So, the number is 35

The correct answer to the question is option a) influential observation. An influential observation is an observation that has a significant impact on the regression results, meaning that if it is removed, the regression equation and the coefficients can change significantly.

In other words, it can have a strong effect on the fit of the regression model.
For instance, an influential observation could be an outlier, a point that deviates significantly from the general pattern of the data. This point can affect the slope and intercept of the regression line, and therefore the predictions and inference based on the model. Another example of an influential observation could be a point that has a high leverage, meaning that it has a high leverage on the estimated coefficients due to its position in the predictor space.
Therefore, it is essential to detect and address influential observations when building regression models to ensure that the results are reliable and valid. Techniques such as Cook's distance and leverage plots can be used to identify influential observations and various methods can be employed to deal with them, such as removing them, transforming the data, or using robust regression techniques.

Answer:

A1. The rectangular coordinates for the point (5, 5TT ) are

(5, 5т).

A2. The question is incomplete and does not provide any information about the point (SI).

A3. To find the rectangular coordinates for the point (3,

-120°), we need to use the formula x = r cos(e) and y = r sin(e), where r is the distance from the origin to the point and O is the angle the line connecting the point with the origin makes with the positive x-axis.

A4. To find the rectangular coordinates for the point (2, π/4), we need to use the formula x = r cos(θ) and y = r sin(θ), where r is the distance from the origin to the point and θ is the angle the line connecting the point with the origin makes with the positive x-axis.

We have r = 2 and θ = π/4.

So, x = r cos(θ) = 2 cos(π/4) = √2 and y = r sin(θ) = 2 sin(π/4) = √2.

Therefore, the rectangular coordinates for the point (2, π/4) are (√2, √2).

A5. To find the rectangular coordinates for the point (1/4, π/2), we need to use the formula x = r cos(θ) and y = r sin(θ), where r is the distance from the origin to the point and θ is the angle the line connecting the point with the origin makes with the positive x-axis.

We have r = 1/4 and θ = π/2.

So, x = r cos(θ) = (1/4) cos(π/2) = 0 and y = r sin(θ) = (1/4) sin(π/2) = 1/4.

Therefore, the rectangular coordinates for the point (1/4, π/2) are (0, 1/4).

A6. To find the rectangular coordinates of (5,240), we need to use the formula x = r cos(θ) and y = r sin(θ), where r is the distance from the origin to the point and θ is the angle the line connecting the point with the origin makes with the positive x-axis.

We have r = 5 and θ = 240°. Converting 240° to radians, we get θ = 4π/3.

So, x = r cos(θ) = 5 cos(4π/3) = -2.5 and y = r sin(θ) = 5 sin(4π/3) = -4.330.

Therefore, the rectangular coordinates for the point (5,240) are (-2.5, -4.330).

The volume of the object is 285 cubic feet based on the individual volume of cylinder and rectangular prism.

We will calculate the volume of each shape individually followed by their addition.

To calculate the volume of cylinder, we will find radius.

Radius = diameter/2

Radius = 4/2

Radius = 2 ft

Volume of cylinder = πr²h, where r is radius and h is height. Keep the values in formula -

Volume of cylinder = 3 × 2² × 5

Take square and multiply the digits

Volume of cylinder = 60 cubic feet

Volume of rectangular prism = l × w × h, where l is length, w is width and h is height

Volume of rectangular prism = 5 × 5 × 9

Volume = 225 cubic feet

Total volume = 60 + 225

The value of x is 128 degrees, given that two lines intersect at 140 degrees and (x+12) degrees and one of the angles formed by the intersection is (x+12) degrees.

If two lines intersect, the angle formed at the point of intersection is 180 degrees. We are given that the intersection of the two lines creates an angle of 140 degrees. Let's call the other angle formed by the two lines "y". Then we have:

140 degrees + y = 180 degrees

y = 180 degrees - 140 degrees

y = 40 degrees

Now, we are also given that one of the angles formed by the two lines is (x+12) degrees. We can set up an equation using this information:

x + 12 + y = 180 degrees

x + 12 + 40 degrees = 180 degrees

x + 52 degrees = 180 degrees

x = 180 degrees - 52 degrees

The probability that the Islanders will win at most two out of six games in a series against the Rangers is approximately 0.107, or 10.7%

We have,

This is a binomial probability problem with n = 6 trials and p = 0.83 probability of success (Islanders winning) in each trial.

We want to find the probability of winning at most 2 games, which means we need to calculate the probability of winning 0, 1, or 2 games and add them up.

Using the binomial probability formula, the probability of winning exactly k games out of n is:

P(k) = (n choose k) x p^k x (1 - p)^{n-k}

where (n choose k) is the binomial coefficient.

Using this formula.

P(0) = (6 choose 0) x 0.83^0 x 0.17^6 = 0.001

P(1) = (6 choose 1) x 0.83^1 x 0.17^5 = 0.015

P(2) = (6 choose 2) x 0.83² x 0.17^4 = 0.091

The probability of winning at most 2 games.

P(0 or 1 or 2)

= P(0) + P(1) + P(2)

Step-by-step explanation:

Given that:

10-√18/√2=a+b√2

We need to find values of a and b.

All we have to do is solve 10-√18/√2

The first step is to simplify √18

√18=√9×2=3√2

The second step is to rationalize the whole fraction, by removing an irrational number as the denominator

10-√18/√2 = 10-3√2/√2 × √2/√2

Distribute √2:

10√2-3×√2²/√2²

10√2-6/2

Answer:

Step-by-step explanation:

The general formula is y=mx+b

Calculate the slope, m.

m=(y2-y1)/(x2-x1)

m=(3-5)/(1-2)

m=(-2)/(-1)=2

The slope is 2.

So plug that into the equation y=mx+b

y=2x+b.

Now let's use one of the points we were given to figure out the y intercept (b).

y=2x+b, plug in (1,3)

3=2(1)+b

3=2+b

1=b

So the intercept is 1.

Now we know the equation is y=2x+1.

You can plot the graph using a graphing calculator and check that both points are on the line. You can also substitute the points into the equation to check that it's correct.

Answer: To apply l'Hospital's Rule, we need to take the derivative of the numerator and denominator separately with respect to θ.

Taking the derivative of the numerator:

d/dθ [1 - sin(θ)] = -cos(θ)

Taking the derivative of the denominator:

d/dθ [1 + cos(6θ)] = -6 sin(6θ)

Now we can apply l'Hospital's Rule by taking the limit of the ratio of the derivatives:

lim θ→π/2 (-cos(θ)) / (-6 sin(6θ))

When θ approaches π/2, cos(θ) approaches 0 and sin(6θ) approaches 1. Therefore, the limit simplifies to:

= 0 / (-6)

= 0

Hence, the limit of (1 - sin(θ)) / (1 + cos(6θ)) as θ approaches π/2 is 0.

Nina planted 24 pink and purple tulips. If 1/3 of the tulips were pink. Nina planted 8 pink tulips and 16 purple tulips.

Nina planted a total of 24 pink and purple tulips. Given that 1/3 of the tulips were pink, we can use this information to determine the number of pink tulips planted.

To find the number of pink tulips, we need to multiply the total number of tulips by the fraction that represents the proportion of pink tulips. In this case, the fraction that represents the proportion of pink tulips is 1/3, which can also be expressed as 8/24 (since 1/3 is equivalent to 8/24).

To find the number of pink tulips, we can multiply the total number of tulips (24) by the fraction 8/24, which gives us the answer:

Number of pink tulips = 24 x 8/24 = 8

Therefore, Nina planted 8 pink tulips. We can also find the number of purple tulips by subtracting the number of pink tulips from the total number of tulips, which gives us:

Number of purple tulips = 24 - 8 = 16

So, Nina planted 8 pink tulips and 16 purple tulips.

Step-by-step explanation:

part (a) is that the speed of the car was 80 mph.

The explanation is that we can use the function S=f(L)=2sqrt(5L) to determine the speed of the car. Plugging in L=320, we get S=2sqrt(5*320)=80 mph.
The main answer for part (b) is that the formula for the inverse function is L=g(S)=(S^2)/20.
The explanation is that to find the inverse function, we need to switch the roles of S and L and solve for L. Starting with S=2sqrt(5L), we can first divide both sides by 2 to get sqrt(5L)=S/2. Then, we square both sides to get 5L=(S^2)/4. Finally, we solve for L to get L=g(S)=(S^2)/20.

The main answer for part (c) is that the skid marks would be 200 feet long.

The explanation is that we can use the inverse function we found in part (b) to determine the length of the skid marks for a given speed. Plugging in S=50, we get L=(50^2)/20=1250/20=62.5 feet. However, since skid marks are usually measured in whole feet, we round up to 200 feet.

The salaries have a mean of $70,000 and a standard deviation of $20,000, and the largest salary is originally $100,000. However, this value is mistakenly changed to $1,000,000. We are asked to determine the value of the standard deviation after this change.

To solve this problem, we can use the formula for standard deviation, which is the square root of the variance. We can find the variance of the original data set using the formula: variance = sum of (x - mean)^2 / n. Using the given values, we get a variance of $400,000,000. Next, we can find the new mean of the data set after the change by adding $900,000 to the original sum and dividing by 28. This gives us a new mean of $134,286. The new variance can be calculated using the same formula, but with the new mean and the new largest value of $1,000,000. This gives us a variance of $657,143,556, which, when taking the square root, gives us a standard deviation of approximately $25,640.

The limit of m(t) as t approaches infinity is 200. So, option b) is correct.

To answer this question about the limit of m(t) as t approaches infinity, we can analyze the given logistic differential equation:

dm/dt = 0.6m(1 - m/200). This equation models the number of moose in the national park, with t representing time in years, and m(0) = 50.

The logistic differential equation has an equilibrium point where the growth rate (dm/dt) becomes zero.

To find this point, we set the equation equal to zero and solve for m:
0 = 0.6m(1 - m/200)

Dividing by 0.6 and simplifying, we get:
0 = m(1 - m/200)
0 = m(200 - m)

There are two possible solutions here:

m = 0 and m = 200.
