What is 9/4 (5/6 - 11/15)

Answer:

E

Step-by-step explanation:

We square the residuals when using the least-squares line method to find the line of best fit because we believe that huge negative residuals (i.e., points well below the line) are just as harmful as large positive residuals (i.e., points that are high above the line).

We treat both positive and negative disparities equally by squaring the residual values.  We cannot discover a single straight line that concurrently minimizes all residuals. The average (squared) residual value is instead minimized.

We might also take the absolute values of the residuals rather than squaring them. Positive disparities are viewed as just as harmful as negative ones under both strategies.

Answer:

\(40^{\circ},\:40^{\circ},\: 100^{\circ}\)

Step-by-step explanation:

The interior angles of any triangle always add up to \(180^{\circ}\). In an isosceles triangle, (at least) two sides are congruent and therefore their base angles are also congruent. We can then form the following equation:

\(2x+2x+5x=180\), where \(x\) is some constant.

Solving, we get:

\(9x=180,\\x=20\)

Therefore, plugging our constant back in, our angles are:

\(2(20),\: 2(20), \: 5(20), \\\fbox{$40^{\circ},\:40^{\circ},\: 100^{\circ}$}\).

Note this is only one group of possible angles. We could've also set the angle represented by \(5x\) to be the pair of angles that are congruent, and depending on your definition of isosceles, each angle measure could be \(60^{\circ}\) (equilateral).

Answer:

100, 40, 40

Step-by-step explanation:

First, do 2x+2x+5x because an isosceles triangle has two equal angles. We know that a triangle's total angle is 180 degrees so we do 180/9=20 x=20. Then multiply 2 by 20 to get 40. Then multiply 5 by 20 to get 100. So you get 40 40 100.

The correct is (C) μ = -0.05 and σ = 0.15. The investigator is using the sample proportion p to estimate the true proportion of red blossoms in his hybrid plants.

The sample proportion p is expected to be normally distributed with a mean of μ = 0.15 and a standard deviation of σ = sqrt(p(1-p)/n), where n is the sample size. Substituting the values given, we get σ = sqrt(0.15(1-0.15)/50) = 0.05. However, since the investigator anticipates that the proportion of red blossoms is 0.15, he expects the sample proportion to be close to this value. Therefore, the mean of the sample proportion distribution should be close to the anticipated proportion, which is 0.15 - p = 0.15 - 0.15 = -0.05. Therefore, the correct answer is (C) μ = -0.05 and σ = 0.15. The investigator's anticipated proportion of red blossoms in his hybrid plants is 0.15. With a random sample of 50 plants, the sample proportion (p) follows a normal distribution. To determine the mean (μ) and standard deviation (σ), we can use the given information:
μ = p = 0.15 (anticipated proportion)
n = 50 (sample size)
We can calculate the standard deviation using the formula for binomial distribution:
σ = √(p(1-p)/n) = √(0.15(1-0.15)/50) = √(0.15*0.85/50) ≈ 0.05
Thus, the correct answer is (B) μ = 0.15 and σ ≈ 0.05.

Answer:

y = 6

Step-by-step explanation:

Therefore, the absolute minimum value of f on the interval [-1, 6] is -1, and the absolute maximum value is 15625.

To find the absolute minimum and absolute maximum values of the function f(x) = (x^2 - 1)^3 on the interval [-1, 6], we need to evaluate the function at its critical points and endpoints.

First, let's find the critical points by taking the derivative of f(x) and setting it equal to zero:

f(x) = (x^2 - 1)^3

f'(x) = 3(x^2 - 1)^2 * 2x

Setting f'(x) = 0, we have:

3(x^2 - 1)^2 * 2x = 0

This equation is satisfied when x = -1, 0, and 1.

Next, we evaluate f(x) at the critical points and endpoints:

f(-1) = (-1^2 - 1)^3 = 0

f(0) = (0^2 - 1)^3 = -1

f(1) = (1^2 - 1)^3 = 0

f(6) = (6^2 - 1)^3 = 25^3 = 15625

Now we compare the function values to determine the absolute minimum and absolute maximum:

The function has an absolute minimum value of -1 at x = 0.

The function has an absolute maximum value of 15625 at x = 6.

Step-by-step explanation:

I have done a Little draw because I don't know how i can explain you this exuse me

The y component of vector B can be found using the equation A×B = 82k. Since vector A = 135i, then the y component of vector B must be 82 / 135.

We know that A×B = |A||B|sinθn, where θ is the angle between A and B, and n is the unit vector perpendicular to both A and B (which points either in the positive or negative z direction).

In this problem, A = 135 i and A×B = 82 k, so we have:

|A||B|sinθn = 82 k

|A| = 135

|A×B| = 82

The magnitude of the cross-product is |A||B|sinθ, so we can solve for sinθ:

|A×B| = |A||B|sinθ

82 = 135|B|sinθ

sinθ = 82 / (135|B|)

Since we know that B is perpendicular to A, we can say that B has the form B = b j, where b is some scalar and j is the unit vector in the y direction. Then we have:

A•B = 0

135(0) + b y = 0

y = 0

But we also know that the cross-product of A and B points in the z direction, so the angle θ between A and B must be in the x-y plane (since A and B are both in the x-y plane). This means that sinθ = 1, so we have:

|A×B| = |A||B|sinθ

82 = 135|B|

|B| = 82 / 135

Therefore, the y component of vector B is:

y = b|j| = b = 0 + b j = (82 / 135) j

So the answer is y = 82 / 135.

An isosceles triangle is a triangle that has congruent base angles.

The angle at the m∠A = 180°- (30° + 70°) = 80°

The two tangent and secant theorem indicates that the half the difference between the arcs CD and AB is; 30°, therefore;

30 = (1/2) × (AB - CD)

The congruence relationship between the segment BC and AB indicates that the base angle of the isosceles triangle ABC and the angle ACB

Therefore, the angle ACB = 55°

The angle at the center a of a circle is twice the angle formed at the circumference of a circle.

Arc AB = 2 × angle ACB = 2 × 55° = 110°

Arc CD = 110 - 2 × 30 = 50°

∠DBC = 50°/2 = 25°

∠DBA = 70° - 25° = 45°

(1+i) ^18 ≈ 4.766×10^6 - 1.632×10^7i. a. To solve (e^-4-2i) ^2, we first need to simplify e^-4-2i. Using Euler's formula, we can rewrite e^-4-2i as e^-4 * e^-2i, which is equivalent to e^-4(cos (-2) +i*sin (-2)). Simplifying further, we get e^-4(cos(2)-i*sin(2)).

Now, we can square this expression to get (e^-4(cos (2)-i*sin (2))) ^2. Using the formula (a+bi)^2 = a^2 - b^2 + 2abi, we get:

(e^-4*cos(2))^2 - (e^-4*sin(2))^2 + 2*e^-4*cos(2)*i*sin(2)

Simplifying, we get:

e^-8 - e^-8*sin^2(2) + 2*e^-4*cos(2)*i*sin(2)

This is the form a+bi, so our final answer is:

a = e^-8 - e^-8*sin^2(2) ≈ 0.0153
b = 2*e^-4*cos(2)*sin(2) ≈ -0.0565

Therefore, (e^-4-2i)^2 ≈ 0.0153 - 0.0565i.

b. To solve (1+i)^18, we can use the binomial theorem, which states that (a+b)^n = Σ(n choose k)a^(n-k)*b^k, where Σ is the sum from k=0 to n. Applying this to (1+i)^18, we get:

(18 choose 0)1^18*i^0 + (18 choose 1)1^17*i^1 + (18 choose 2)1^16*i^2 + ... + (18 choose 18)1^0*i^18

Simplifying the coefficients using the formula (n choose k) = n!/((n-k)!k!), we get:

1 + 18i - 1530 - 3060i + 18564 + 145152i - 437580 - 947736i + 1352078 + 1081664i - 587863.5 - 575784i + 203887.5 + 405528i - 88749 + 35064i - 5400 + 304i

Adding up the real and imaginary parts separately, we get:

a = 4766436 ≈ 4.766×10^6
b = -16318512 ≈ -1.632×10^7

Therefore, (1+i)^18 ≈ 4.766×10^6 - 1.632×10^7i.

The solution to the system of inequalities y ≤ 2x + 2 and y < -2x - 3 can be represented by a graph. The inequality y ≤ 2x + 2 represents a line with a slope of 2 and y-intercept of 2. The inequality y < -2x - 3 represents a line with a slope of -2 and y-intercept of -3. ( The graph attached)

The inequality y ≤ 2x + 2 represents a line in the form y = mx + b, where m is the slope and b is the y-intercept. In this case, the slope is 2 and the y-intercept is 2. To graph this inequality, we can first plot the line by using the y-intercept, which is the point (0,2) on the graph. Then, we can use the slope to find additional points that fall on the line, such as (1,4) or (-1,0). Once we have plotted several points, we can connect them to form the line.

The inequality y < -2x - 3 represents a similar line, but with a different slope and y-intercept. In this case, the slope is -2 and the y-intercept is -3. To graph this inequality, we can use the same process as before by first plotting the y-intercept (0,-3), and then using the slope to find additional points that fall on the line.

The solution to the system of inequalities is the area that lies on one side of the first line and the opposite side of the second line, which is the area between the two lines. This area can be represented by shading the region below the first line and above the second line on the graph. It is important to note that the solution region is not including the lines themselves, because the inequalities are strict inequalities.

Simply put, probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes. Statistics is the study of events that follow a probability distribution.

By simply dividing the favorable number of possibilities by the entire number of possible outcomes, the probability of an occurrence can be determined using the probability formula.

The probability is computed by dividing the total number of possible outcomes by the number of possible ways the event could occur. Probability and odds are two distinct ideas. Odds are calculated by dividing the likelihood of an event by the likelihood that it won't.

Expected = ∑ value * probability
