6) Which is an equation of the line with a slope of -4 and a y-intercept of -2?
x - 4y = 8 x + 4y = -8
4x + y = -2
4x - y = 2

Answer:

85%

Step-by-step explanation:

P(a) = 25%=1/4

P(b) = 60%=3/5

P(a and b) = 1/4 + 3/5 = 5+12/20 = 17/20 = 85%

Answer:

The probability of A and B is 85%

Step-by-step explanation:

It is 85% because 25% is 0.25 or 25/100(1/4), and 60% is 0.6 or 6/10(3/5). 0.6+0.25=0.85 and to convert it back to a percentage you need to times 100%. 0.85x100%=0.85x100 with a percentage symbol =85%.

The value of the definite integral ∫[ (4x^3 - 6x^2 + 1) dx] from 1 to 2 can be evaluated using the definition of the definite integral as the limit of Riemann sums.

We start by partitioning the interval [1, 2] into n subintervals of equal width Δx = (2 - 1)/n = 1/n. Let xi be the sample point in each subinterval, where xi = 1 + (i-1)(Δx).

The Riemann sum for the given function over the interval [1, 2] is:

Σ[ (4xi^3 - 6xi^2 + 1) Δx] from i = 1 to n

Expanding the terms, we have:

Σ[ (4(1 + (i-1)(Δx))^3 - 6(1 + (i-1)(Δx))^2 + 1) Δx] from i = 1 to n

Simplifying and factoring Δx, we get:

Σ[ (4(1 + (i-1)/n)^3 - 6(1 + (i-1)/n)^2 + 1) ] Δx from i = 1 to n

Taking the limit as n approaches infinity, this Riemann sum becomes the definite integral:

∫[ (4x^3 - 6x^2 + 1) dx] from 1 to 2

To compute the integral, we can find the antiderivative of the integrand, which is (x^4 - 2x^3 + x) evaluated at the limits of integration:

∫[ (4x^3 - 6x^2 + 1) dx] from 1 to 2 = [(2^4 - 2(2)^3 + 2) - (1^4 - 2(1)^3 + 1)]

Simplifying further, we obtain the numerical value of the definite integral.

Answer:

The possible number of students in Mrs. Hayko's class is limited to 15 or 30, as higher multiples of 15 would exceed the desired class size.

Step-by-step explanation:

a)

Let 'x' be the total number of students in Mrs. Hayko's class.

One-third of the students walk to school: (1/3)x.

The remaining students who do not walk to school: (2/3)x.

Four-fifths of the non-walking students take the bus: (4/5) * (2/3)x.

Simplify to find the fraction of students taking the bus: (8/15)x.

b)

Consider different values for 'x' to find a whole number of students taking the bus.

Start with a small number, such as x = 15.

Calculate the number of students taking the bus using (8/15)x.

If the result is a whole number, it's a possible class size.

Repeat with different values of 'x' until a whole number is obtained.

The possible number of students in Mrs. Hayko's class could be 15, 30, or any other multiple of 15.

The unknown value in the table using the constant of proportionality is; 96

The constant of proportionality is the ratio of two proportional values at a constant value. Two variable values have a proportional relationship when either their ratio or their product gives a constant.

We are given the coordinates;

(12, 42), (18, 63), (40, y)

where x-values represents time in seconds and y-values represents number of pencils that were produced.

To find the constant of proportionality is as good as finding the slope between two consecutive points as;

m = (63 - 18)/(42 - 12)

m = (45/30)

m = 1.5

Thus to find the unknown value y, we will use the formula;

(y - y1)/x - x1) = m

So we will use the coordinates; (18, 63), (40, y)

Plugging them into the formula above will result in;

(y - 63)/(40 - 18) = 1.5

y - 63 = 1.5 * 22

y - 63 = 33

y = 33 + 63

y = 96

Thus, we can conclude that using the constant of proportionality, the number of pencils that were produced after a time of 40 seconds is 96 pencils.

Answer:

y = 12x + -10

Step-by-step explanation:

sorry if its wrong i tried

Using a coefficient of 3 for x, the equation for the tangent plane is 2x² + 4y² + z² = 26.

x = 3 + 12t, y = 1 + 8t, and z = 2 + 4t.

The equation for the tangent plane and the normal line at the point Po(3,1,2) on the surface 2x^2 + 4y^2 +z^2 = 26 are:

The equation for the tangent plane is:2x² + 4y² + z² = 26

If we take the gradient of this function, it gives us the normal to the surface at each point.

2x² + 4y² + z² = 26

The gradient of this function gives us the normal to the surface at each point, so if we differentiate the function with respect to x, y, and z, we get:

∂f/∂x = 4x

∂f/∂y = 8y

∂f/∂z = 2z

Therefore, the normal vector is given by N = <4x, 8y, 2z>.

Now we need to find the normal vector at the point Po(3,1,2). So we plug in these values into the normal vector equation:

N(3,1,2) = <4(3), 8(1), 2(2)> = <12, 8, 4>

Therefore, the normal vector to the surface at the point Po(3,1,2) is N = <12, 8, 4>.

Using the coefficient of 3 for x, the equation for the tangent plane is:

2x² + 4y² + z² = 26

At Po(3,1,2), the equation becomes:

2(3)² + 4(1)² + (2)² = 26or18 + 4 + 4 = 26or26 = 26

Thus, the equation of the tangent plane is:

2x² + 4y² + z² = 26

The equation of the normal line at Po(3,1,2) is given by:  x= __, y=__, z=__

We are given the point Po(3,1,2) and the normal vector N = <12, 8, 4>. We also know that the normal line passes through Po, so we can use this information to find the equation of the normal line.

Let x = 3 + 12t (since the coefficient of x is 12). Then the corresponding values for y and z are given by:

y = 1 + 8tandz = 2 + 4t

Thus, the equation of the normal line is:

x = 3 + 12ty = 1 + 8tz = 2 + 4t

Therefore, x = 3 + 12t, y = 1 + 8t, and z = 2 + 4t.

The area of the sector with a central angle of 60 degree and radius of 8 units is approximately 33.5 sqaure units.

A sector of a circle is simply part of a circle made up of an arc and two radii.

The area of a sector of a circle can be expressed as:

Area = (θ/360º) × πr²

Where θ is the sector angle in degrees, and r is the radius of the circle.

From the image:

Measure of central angle θ = 60 degrees

Radius r = 8 units

Plug these values into the above formula and solve for the area:

Area = (θ/360º) × πr²

Area = (60°/360°) × π × 8²

Area = 1/6 × π × 64

Area = 1/6 × π × 64

Area = 33.5 sqaure units.

Therefore, the area is approximately 33.5 sqaure units.

The rational function R(x) = 17x/(x+5) has one vertical asymptote at x = -5, no horizontal asymptote, and no oblique asymptote.

To determine the vertical asymptotes of the rational function, we need to find the values of x that make the denominator equal to zero. In this case, the denominator is x+5, so the vertical asymptote occurs when x+5 = 0, which gives x = -5. Therefore, the function has one vertical asymptote at x = -5.

To find the horizontal asymptotes, we examine the behavior of the function as x approaches positive and negative infinity. For this rational function, the degree of the numerator is 1 and the degree of the denominator is also 1. Since the degrees are the same, we divide the leading coefficients of the numerator and denominator to determine the horizontal asymptote.

The leading coefficient of the numerator is 17 and the leading coefficient of the denominator is 1. Thus, the horizontal asymptote is given by y = 17/1, which simplifies to y = 17.

Therefore, the function has one horizontal asymptote at y = 17.

As for oblique asymptotes, they occur when the degree of the numerator is exactly one greater than the degree of the denominator. In this case, the degrees are the same, so there are no oblique asymptotes.

To summarize, the function R(x) = 17x/(x+5) has one vertical asymptote at x = -5, one horizontal asymptote at y = 17, and no oblique asymptotes.

The correct answer is (a) 3000.

To find the expected number of times we get a 2 or a 3 when rolling the loaded die 6000 times, we need to calculate the probability of getting a 2 or a 3 and multiply it by the total number of rolls.

The probability of getting a 2 or a 3 is the sum of their respective probabilities:

P(2 or 3) = P(2) + P(3) = 0.2 + 0.3 = 0.5

So, the probability of getting a 2 or a 3 in a single roll is 0.5.

To find the expected number of times we get a 2 or a 3 in 6000 rolls, we multiply the probability by the total number of rolls:

Expected number = P(2 or 3) * Total number of rolls = 0.5 * 6000 = 3000

Therefore, the expected number of times we get a 2 or a 3 when rolling the loaded die 6000 times is 3000.

Hence, the correct answer is (a) 3000.

The observation is located to the left of the mean by a distance of 1.2 standard deviations.

The z-score of an observation represents the number of standard deviations the observation is away from the mean.

If the z-score for a particular observation is z = -1.2, this means that the observation is 1.2 standard deviations below the mean.

If the mean is represented by μ and the standard deviation by σ, then we can express this observation as:

observation = μ + (z * σ)

observation = μ + (-1.2 * σ)

This means that the observation is located to the left of the mean by a distance of 1.2 standard deviations.

For example, The z-score represents the number of standard deviations an observation is above or below the mean of the distribution.

In Milgram's first study of obedience, participants were assigned the role of 'teacher' and were instructed to administer electric shocks to a 'learner' whenever they answered a question incorrectly. The shocks ranged from mild to severe, with the highest level labeled as 'XXX.' The learner was actually an actor, and no real shocks were administered.

The study found that the majority of teachers initially complied with the experimenter's orders and delivered shocks, but they refused to deliver more than slight levels of shock. This suggests that while they were willing to follow the instructions to some extent, they had moral reservations about causing significant harm to another person.
