Answer:

y = -x +2

Step-by-step explanation:

4x + 4y = 8 to its slope-intercept form, y = mx + b:

Subtract 4x from both sides of the equation:

4x + 4y - 4x = 8 - 4x

4y = -4x + 8

Divide both sides of the equation by 4 to isolate y:

\(\frac{4y}{4} = \frac{-4x}{4} + \frac{8}{4}\)

y = -x + 2

The probability that a class will be taught in building e is 0.15.

The probability that a class will be taught in building e is 0.15. To calculate this, we need to know the total probability of all the other buildings. The total probability of buildings a, b, c, and d is 0.40 + 0.15 + 0.10 + 0.20 = 0.85. Since there are five buildings on campus, the probability that a class will be taught in building e must be the remainder of 1.00 minus the total probability of the other buildings, which is 0.15.

To understand the calculation of probability, it is important to remember that probabilities must always add up to 1.00, or 100%. This means that when we calculate the probability of one event, we can find the probability of the remaining events by subtracting the calculated probability from 1.00. For example, if we know the probability of a coin being heads is 0.50, then the probability of the coin being tails must be 0.50, since 0.50 + 0.50 = 1.00.

This same principle applies to our question about the five buildings on campus. Since the total probability of buildings a, b, c, and d is 0.85, then the probability of building e must be 0.15 (1.00 - 0.85). This is because the probabilities of buildings a, b, c, d, and e must all add up to 1.00.

Therefore, the probability that a class will be taught in building e is 0.15.

Step-by-step explanation:

3x + 7y = 14

y = x - 8

3x + 7(x - 8) = 14

3x + 7x - 56 = 14

10x - 56 = 14

Add 56 to both sides.

10x = 70

Divide both sides by 10.

x = 7

3(7) + 7y = 14

21 + 7y = 14

Subtract 21 from both sides.

7y = -7

Divide both sides by 7.

Step-by-step explanation:

The Volume of a Cube

Given a cube-shaped figure of side length L, the volume is calculated by:

\(V=L^3\)

If the volume is known, then the side length can be found by solving for L:

\(L=\sqrt[3]{L}\)

We are given three cube-shaped blocks with known volumes. We'll find the individual side lengths and add them up to find the height that results when they stack up vertically.

Block 1, volume 375 cube inches:

\(L_1=\sqrt[3]{375}=7.21\ inch\)

Block 2, volume 648 cube inches:

\(L_2=\sqrt[3]{648}=8.65\ inch\)

Block 3, volume 1029 cube inches:

\(L_3=\sqrt[3]{1029}=10.10\ inch\)

Total height=7.21 inch+8.65 inch+10.10 inch=25.96 inch

Step-by-step explanation:

It is False that based only on the r and p values listed above you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

In the given scenario, it is not completely true that based only on the r and p values listed above, you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

Let's first understand what is meant by the term "moderator.

"Moderator: A moderator variable is a variable that changes the strength of a connection between two variables. If there is a statistically significant bivariate relationship between the amount of texting during driving and the number of accidents, scientists investigate whether this bivariate relationship is moderated by age.

Therefore, based on the values of r and p, it is difficult to determine if age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

As we have to analyze other factors also to determine whether the age is a moderator or not, such as the sample size, the effect size, and other aspects to draw a meaningful conclusion.

So, it is False that based only on the r and p values listed above you can come to the conclusion that age is a moderator of the bivariate relationship between the amount of texting and the number of accidents.

3C=900-10A

Step-by-step explanation:

The given equation can be written to represent C as a function of A and A as a function of C as  C = 300 - 10/3A and  A = 90 - 3/10C respectively.

A function y = f(x) is a one to one relationship between two sets X and Y where the set X is called the domain and Y the range of function f(x) ans x ∈ X and y ∈ Y.

(a) The function for the cost of tickets is given as 10A + 3C = 900.

It can be written to represent C in terms of A as,

10A + 3C = 900

⇒ 3C = 900 - 10A

⇒ C = 300 - 10/3A

(b) It can be written to represent A in terms of C as,

10A + 3C = 900

⇒ 10A = 900 - 3C

⇒ A = 90 - 3/10C

To find curvature of a plane curve at a given point, we need to calculate radius of curvature of curve at that point. The formula for the radius of curvature is given by: R =\([(1 + (dy/dx)^2)^(3/2)]/|d^2y/dx^2|\). The curvature of curve \(y=-2t^4\) at point t=1 is K(1) = 1/R = 2/17.

where dy/dx is the slope of the tangent to the curve at the point, and \(d^2y/dx^2\)is the second derivative of y with respect to x. In this case, we have\(y = -2t^4\), so \(dy/dx = -8t^3\) and \(d^2y/dx^2 = -24t^2.\)  At t=1, we have dy/dx = -8 and\(d^2y/dx^2 = -24.\) Substituting these values into the formula for R, we get: \(R = [(1 + (-8)^2)^(3/2)]/|-24| = 17/2,\) Therefore, the curvature of the curve\(y=-2t^4\) at the point t=1 is K(1) = 1/R = 2/17.

The curvature of a curve measures the rate at which the direction of the tangent to the curve changes as we move along the curve. A higher curvature indicates a sharper turn, while a lower curvature indicates a more gradual curve. In this case, the curvature is quite small, indicating a relatively gentle curve at the point t=1.

The margin of sampling error for a 95% confidence interval is 9.7%

The formula for margin of error here is;

E = z√(p(1 - p)/N)

where;

n is sample size

z is the z score

p is the sample proportion

z-score for a 95% confidence interval from tables is 1.96.

We are given;

p = 43% = 0.43

n = 100

Thus;

E = 1.96√(0.43(1 - 0.43)/100)

E =  0.097 = 9.7%

Using the normal distribution formula, we know that the z score that is equivalent to 25 is 1.5.

A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.

The characteristics of normal distributions are as follows: Bell-like in its symmetry.

The distribution's mean and median, which are both at its center, are equal.

68 percent of the data, or approximately, falls within one standard deviation of the mean.

So, the formula is used to determine the Z score for a data point x in a normal distribution:

Z = z - mean/standard deviation

Now, use the formula to calculate the z value as follows:

Z = z - mean/standard deviation

Z = 25 - 16/6

Z = 9/6

Z = 3/2

Z = 1.5

Therefore, using the normal distribution formula, we know that the z score that is equivalent to 25 is 1.5.

Based on the explanation using the combination method, the correct answer to the question is D. All four users have non-expiring passwords.

The MBSA scan likely provided a list of users along with their corresponding password expiration settings. The term "non-expiring passwords" refers to passwords that do not have an expiration date, meaning they remain valid indefinitely.

Now, let's analyze each option given in the question and determine the correct answer using the combination method:

A. 3 of 4:

If three out of the four users have non-expiring passwords, it means that only one user has an expiring password. However, this does not match our definition of non-expiring passwords. Therefore, Option A is incorrect.

B. 1 of 4:

If only one user out of the four has a non-expiring password, it means that the other three users have expiring passwords. This option does not satisfy the condition of non-expiring passwords for the majority of users. Hence, Option B is also incorrect.

C. 2 of 4:

If two users out of the four have non-expiring passwords, it means that the remaining two users have expiring passwords. This option suggests that half of the users have non-expiring passwords, which does not correspond to our definition of non-expiring passwords for the majority of users. Thus, Option C is incorrect.

D. 4 of 4:

If all four users have non-expiring passwords, it means that every user's password is set to never expire. This option aligns with our definition of non-expiring passwords for the majority of users. Therefore, Option D is the correct answer.
