a shift of 3 squares right means add 3 to the x- coordinate
a shift of 1 square down means subtract 1 from the y- coordinate
translation rule is (x, y ) → (x + 3, y - 1 ) , then
(1, 1 ) → (1 + 3, 1 - 1 ) → (4, 0 )
(1, 4 ) → (1 + 3, 4 - 1 ) → (4, 3 )

What is the last digit of the product of all the numbers between 11 and 29?
we can conclude that the last digit of the product of all the numbers between 11 and 29 is 0.
What is the last digit of the product of all the numbers between 11 and 29?
Here we want to find the last digit of the product between all the whole numbers larger than 11 and smaller than 29.
Then we have the product:
P = 12*13*14*15*16*17*18*19*20*21*22*23*24*25*26*27*28
Now, notice that there is a 20 there.
Any number times 20 will end with a zero, then:
P = 20*(12*13*14*15*16*17*18*19*21*22*23*24*25*26*27*28)
Only with that, we can conclude that the last digit of the product of all the numbers between 11 and 29 is 0.

The time it takes me to wash the dishes is uniformly distributed between 12 minutes and 20 minutes. What is the probability that washing dishes tonight will take me between 16 and 19 minutes?
Answer:
14.29% probability that washing dishes tonight will take between 14 and 15 minutes.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d is given by the following formula.
The time it takes me to wash the dishes is uniformly distributed between 11 minutes and 18 minutes.
This means that

Triangle ABC measures are as follows; Angle A measures 30 degrees, angle B measures (3x-9) degrees and angle C measures 29 degrees. What is the value of x?
Answer:
x = 43 1/3 degrees
Step-by-step explanation:
sum of interior angles in a triangle = 180 degrees
30 + (3x - 9) + 29 = 180
30 + 29 + (3x - 9) = 180
59 + (3x - 9) = 180
(3x - 9) = 180 - 59
(3x - 9) = 121
3x = 121 + 9
3x = 130
x = 43 1/3

a kite flying in the air has a 94- string attached to it, and the string is pulled taut. the angle of elevation of the kite is . find the height of the kite. round your answer to the nearest tenth.
The height of the kite is approximately 68.4 ft.
To solve the problem, we can use trigonometry. We know that the string is the hypotenuse of a right triangle, with the height of the kite as one of the legs. The angle of elevation, which is the angle between the string and the ground, is also given. We can use the tangent function to find the height of the kite:
tan(46°) = height / 94
Solving for height, we get:
height = 94 * tan(46°)
Using a calculator, we get:
height ≈ 68.4 ft
Therefore, the height of the kite is approximately 68.4 ft.
We use the given angle of elevation and the length of the string to set up a right triangle with the height of the kite as one of the legs. Then, we use the tangent function to relate the angle to the height of the kite. Finally, we solve for the height using a calculator and round to the nearest tenth as requested.

standard error of an estimator is not affected by the multiple choice question. population standard deviation. sample size. population size
The term that is not affected the standard error of an estimator is population size, from the provide data in options. So, option (c) is right one.
The standard error is a statistical term that used to measured the accuracy that a sample distribution represents a population by using standard deviation. The standard error(SE) is very similar to standard deviation of a distribution. Both are used to measure the spread of distribution. Higher the value SE, the more spread out your data is. In statistical way, standard error is also called standard error of mean, SEM, it represents the deviation of sample mean deviates from the actual mean of a population.
It is calculated simply by dividing the standard deviation by the square root of the sample size. That is \(SE = \frac{σ }{\sqrt{n}}\)
where , n --> sample size
σ --> population standard deviations
Now, from the above formula it is clearly seen that standard error term or an estimator affected by sample size (n) and population standard deviations ( σ). So, right choice for answer is population size.

The number of plants Ethan has are 5.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let x be the number of plants Ethan has.
Ethan uses 3.5 ounces of water for each plant, so he will use a total of 3.5p ounces of water.
If he starts with 32 ounces of water and ends up with 14.5 ounces
Total of 32 - 14.5 = 17.5 ounces of water.
As given the amount of water used is equal to the amount of water per plant times the number of plants:

The statistics indicate that the assumption that the four populations have the same standard deviation has been broken.
a. This research was done via observation.
False, as this is a test. (unlike what Alex89 says). The response variable (minutes of rest) is then recorded because the researcher randomly assigns the fruit flies to one of the treatments, using a TREATMENT, and records the response variable.
b. The statistics indicate that the assumption that the four populations have the same standard deviation has been broken.
False: There is no deviation from the equality of standard deviations. We DO NOT need to test this assumption when the sample sizes are equal. Even if we did, 29.61/19.08 = 1.55 2 means that the greatest standard deviation is less than twice the lowest standard deviation. We are therefore okay.
c. Because ANOVA needs sample sizes, it may be applied to this data are equal.
False - The ANOVA does NOT require equal sample sizes.
3. The correct option is D, For this example, we notice that 3) None of the above
(4) The correct is option A, which states that 4) the population mean rest is the same for all four caffeine concentrations.
Statistics provides a framework for making informed decisions based on data by using methods such as probability theory, hypothesis testing, regression analysis, and statistical modeling. The importance of statistics lies in its ability to transform raw data into meaningful information that can be used to make decisions, develop policies, and solve problems in a wide range of fields, including business, healthcare, government, and social sciences.
Statisticians use various tools and techniques to summarize and describe data, identify patterns and relationships, and make predictions and inferences.

How much money is pictured below?
Answer:$1. 45
Step-by-step explanation:
The bill is $1
the quarter is .25
and the nickels together are .20
add everything together its 1.45
First, we need to know the value of each coin. The top coin is a quarter, and its value is $0.25. The four coins below are nickels, and they have a value of $0.05. The dollar bill at the bottom has a value of $1.00.
If we have one quarter, we start with a value of $0.25.
\($0.25\)
Now, we add on the nickels.
\(0.25 + 0.05+ 0.05+ 0.05+ 0.05 = 0.45\)
Now we have a total of $0.45.
Adding the dollar would look like this:
\(1.00 + 0.45 = 1.45\)
Therefore, the value of all the money in the picture is $1.45.

Locate and identify the absolute extreme values of the following functions
The absolute extreme value of the function ln (cos 3x) in interval [-π/12, π/9] is 0 at point x = 0.
Given the function is,
f(x) = ln (cos 3x), where x belongs to the closed interval [-π/12, π/9]
Differentiating the function with respect to 'x' we get,
f'(x) = (1/cos 3x)*(- sin 3x)*3 = -3tan 3x
f''(x) = -3 (sec² 3x)*3 = -9 sec² 3x
Now f'(x) = 0 gives,
-3 tan 3x = 0
tan 3x = 0
3x = ..., -π, 0, π, ....
So, x = ...., -π/3, 0, π/3, .....
So the absolute value of x which lies in [-π/12, π/9] is, x = 0.
At x = 0,
f''(0) = -9 sec² (3*0) = -9 sec²0 = -9 < 0
So at x = 0, the function has maximum value.
Max f(x) = f(0) = ln( cos 3*0) = ln 1 = 0
Hence the maximum value of function is also 0.
