The transformation from point (-3, -3) to point (4, -5) is the same transformation from point (-1, -7) to the missing point.
Let's find the transformation from point (-3, -3) to point (4, -5).
x: 4 - (-3) = 7
y: -5 - (-3) = -2
Now we apply a transformation of 7 in x and -2 in y to (-1, -7).
(-1 + 7, -7 + (-2)) = (6, -9)
Answer: (6, -9)
sum of independent negative binomial random variable and geometric random variable
The sum of independent negative binomial and geometric random variables does not have a closed-form distribution and must be computed numerically.
What is binomial random variable ?
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success or failure.
Let X be a negative binomial random variable with parameters r and p, and let Y be a geometric random variable with parameter q. The sum Z = X + Y is also a random variable.
The cumulative distribution function (CDF) of Z is given by:
F_Z(z) = P(Z <= z) = P(X + Y <= z) = ∑_{x=0}^{z} P(X = x) * P(Y = z - x)
This expression is a double sum and does not have a closed-form solution, but it can be computed numerically.
Alternatively, the probability mass function (PMF) of Z can be found by counting the number of ways that X and Y can take on their respective values, and summing up their joint probabilities:
f_Z(z) = P(Z = z) = ∑_{x=0}^{z} P(X = x) * P(Y = z - x)
The sum of independent negative binomial and geometric random variables does not have a closed-form distribution and must be computed numerically.

Whats the answer for this 14=-(p-8)
Answer: " p = - 6 " .
___________________________________
Step-by-step explanation:
___________________________________
Given: 14 = - (p - 8) ; Solve for "p" ;
Rewrite as:
↔ - (p - 8) = 14 ;
which is the same as:
-1(p - 8) = 14 ; ;
Divide each side by "-1" ; to get rid of the "-1" ;
{-1(p - 8) } / -1 = {14} / -1 ;
to get:
(p - 8) = -14 ;
Rewrite as:
p - 8 = -14 ;
Now add "8" to each side of the equation;
to isolate "p" on one side of the equation; & to solve for "p" :
p - 8 + 8 = -14 + 8 ;
to get:
p = - 6 ;
which is the answer:
___________________________________
p = - 6 .
___________________________________
Now, let us check our answer:
___________________________________
Given: 14 = - (p - 8) ;
Substitute our solved value: "-6" ; for "p" ; to see if the equation holds true:
___________________________________
14 = - (p - 8) ;
14 =? -(-6 - 8) ;
14 =? -(-14) ;
14 =? + 14 ? Yes!
__________________________________
Hope this answer and explanation is helpful to you!
__________________________________
Step-by-step explanation:
Hey there!
Here;
14 = -(p-8) is given.
Perform the operations in right hand side.
\(14 = - p + 8\)
Shift "p" in left side and "14" in right side.
\(p = 8 - 14\)
\(p = - 6\)
Therefore the value of p is -6.
Check;
14 = -(-6-8)
14 = +6+8
14=14 (True).

Morty does not try hard at work, because he believes that promotions are completely random and that he has no control over whether he will get promoted. According to expectancy theory, Morty most likely has a(n) ________ locus of control
Morty most likely has an external locus of control according to expectancy theory, which suggests that he believes outcomes are determined by external factors and not within his control.
Expectancy theory is a psychological framework that examines individuals' motivation and decision-making processes. It posits that people's motivation to exert effort is influenced by three key factors: expectancy, instrumentality, and valence.
Locus of control is an important concept within expectancy theory and refers to individuals' beliefs about the degree to which they have control over the outcomes in their lives.
In Morty's case, his belief that promotions are completely random and beyond his control indicates an external locus of control.
He perceives promotions as being determined by external factors such as luck or favoritism, rather than his own efforts or abilities.
This belief diminishes his motivation to try hard at work because he does not see a direct link between his performance and the desired outcome of promotion.
Individuals with an external locus of control tend to attribute outcomes to external forces, such as luck or fate, rather than their own actions.
They may feel powerless and have lower motivation to actively pursue their goals or exert effort to achieve desired outcomes.
In Morty's case, his perception that promotions are random suggests that he lacks the belief that his efforts will directly influence his chances of promotion, leading to reduced motivation and a lack of effort in his work.

Describe the difference between null vs alternative hypothesis
Statistical hypothesis testing employs the null and alternate hypotheses.
The alternative hypothesis of a test expresses the prediction of an effect or relationship based on your study, while the null hypothesis of the test does not yet predict an effect or an association between the variables.
A statement that there is no relationship between two variables is called a null hypothesis. Another hypothesis is that the two variables are statistically correlated.
Alternative unilateral (directional) or the bilateral (non-directional) hypotheses are also possible. Simple, complex, true, and false are the four main categories of null hypotheses. If the p-value is greater than the statistical significance level, null hypothesis is preferred.

When solving problems where you need the sampling distribution of r, what is the reason for converting from r to z'?
The sampling distributions of r is not normal distribution, Hence by applying fisher's z -transformation.
What is correlation coefficient ?A statistical indicator of the degree to which two variables move in tandem with one another is the correlation coefficient. Between -1.0 and 1.0 are the possible values. An error in the correlation measurement is indicated by a calculated number that is larger than 1.0 or less than -1.0. The perfect correlation is shown by a correlation of -1.0 for a perfect negative correlation and 1.0 for a perfect positive correlation. The movement of the two variables do not move in a linear manner, as indicated by a correlation of 0.
We need sampling of r to test for the significance of population correlation coefficient. In testing for P, The sampling distributions of r is not normal distribution Hence by applying fisher's z -transformation, we convert r to Z then 7 approximately follows normal distribution.

Ingrid dug a trench eighteen twentieths of a meter long. The next day she dug nine twentieths of a meter more of the trench. What is a reasonable estimate of the total length of the trench?
Answer:
1.00 meter.
Step-by-step explanation:
For the first day, she dug eighteen twentieth of a meter = \(\frac{18}{20}\) x 1 meter
= \(\frac{9}{10}\) meters
The second day, she dug nine twentieth of a mater = \(\frac{9}{20}\) x 1 meter
= \(\frac{9}{20}\) meters
Total length of the trench = \(\frac{9}{10}\) + \(\frac{9}{20}\)
= \(\frac{18 + 9}{20}\)
= \(\frac{27}{20}\)
= 1\(\frac{7}{20}\)
= 1.35 meters
Total length of the trench is 1.35 meters.
A reasonable estimate of the total length of the trench is 1.00 meter.
Answer:
It is 1 and 1 half. or C
Step-by-step explanation:
It is 18/20 + 9/20. 18 + 9 = 27, and there is (number)/20. since it is 20 it will get 1 whole. now there is just 7, and 7 you round up to 1 half because 5 and over round up, while 4 and under round down.

Suppose that, from measurements in a microscope, you determine that a certain bacterium covers an area of 1. 50μm2. Convert this to square meters.
Converting 1. 50μm² to square meters gives 1. 5 × 10 ^-11
What is conversion of units?Conversion of units is defined as the conversion of different units of measurement for the same quantity, mostly through multiplicative conversion factors.
From the information given, we are to convert micrometers to square meters
Note that:
1 micrometer ( μm²) = 10^-12m²
Given 1. 50μm² = xm²
cross multiply
x = 1. 50 × 10^-12
x = 1. 50 × 10^-12
x = 1. 50 × 10^-12
x = 1. 5 × 10 ^-11 square meters
Thus, converting 1. 50μm² to square meters gives 1. 5 × 10 ^-11

Consider a binomial random variable with n = 6 and p = 0.8. Let x be the number of successes in the sample.
a) Find the probability that x is 3 or less.
b) Find the probability that x is 3 or more.
c) Find P(x < 3).
d) Find P(x = 3).
a) To find the probability that x is 3 or less, we need to calculate P(x ≤ 3) using the binomial probability formula or a binomial probability table.
b) To find the probability that x is 3 or more, we can use the complement rule. P(x ≥ 3) = 1 - P(x < 3).
c) P(x < 3) is the same as P(x ≤ 2) since we are excluding 3. We can calculate it using the binomial probability formula or a binomial probability table.
d) P(x = 3) is the probability of getting exactly 3 successes in the sample, which can be calculated using the binomial probability formula.
a) To find the probability that x is 3 or less, we sum up the individual probabilities of getting 0, 1, 2, or 3 successes in the sample. This can be calculated using the binomial probability formula:
P(x ≤ 3) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)
b) To find the probability that x is 3 or more, we can use the complement rule. Since the complement of "x is 3 or more" is "x is less than 3," we can calculate P(x < 3) and then subtract it from 1:
P(x ≥ 3) = 1 - P(x < 3)
c) P(x < 3) is the probability of getting less than 3 successes in the sample. This includes the probabilities of getting 0, 1, or 2 successes:
P(x < 3) = P(x = 0) + P(x = 1) + P(x = 2)
d) P(x = 3) is the probability of getting exactly 3 successes in the sample. It is a specific outcome among all possible outcomes, so we calculate it directly using the binomial probability formula:
P(x = 3) = nCk * p^k * (1 - p)^(n - k)
