graph the image of square abcdafter a translation 11 units left and 5 units up
Answers
Answer:
Explanation:
Here, we want to graph the new image of ABCD
What this means is that we get a new set of coordinates for each of the points
Let us look at the translation rule here, the rule is that the points move 11 units left and 5 units up
What that simply means is that we subtract 11 from the x-axis value, then add 5 to the y-axis value
We have that as follows:
A is (2,-8)
A' becomes (2-11, -8 + 5) which is (-9,-3)
B is (9,-8)
B' becomes (9-11, -8+5) which is (-2,-3)
C is (9,-1)
C' becomes (9-11 , -1+5) which is (-2,4)
D is (2,-1)
D' becomes (2-11,-1+5) which is (
Adena, Julius, and Tia volunteered to read to children at the public library. Julius worked two hours less than Tia. Adena worked twice as many hours as Julius. Altogether they worked 58 hours. How many hours did Adena work?
Answers
Answer:
28 hours
Step-by-step explanation:
Adena, Julius, and Tia volunteered to read to children at the public library.
Let us represent, the number of hours worked by
Adena = x
Julius = y
Tia = z
Julius worked two hours less than Tia.
y = z - 2
z = y + 2
Adena worked twice as many hours as Julius.
x = 2y
Altogether they worked 58 hours.
x + y + z = 58.... Equation 1
We substitute 2y for x and y + 2 for z in Equation 1
2y + y + y + 2 = 58
4y + 2 = 58
Collect like terms
4y = 58 - 2
4y = 56
y = 56/4
y = 14
We are the find the number of hours Adena worked which is represented by x
Note that:
x = 2y
y = 14, hence,
x = 2 × 14
x = 28 hours
Therefore, the number of hours Adena worked is 28 hours

4 Measures of central tendency show how data has a tendency to move away from the center True False QUESTION 5 Measures of central tendency measure the center of the data True False QUESTION 6 "Inferential" statistics means studding a population to make inferences about its smaller units like a sample True False
Answers
The sentences are 4 = false, 5 = true and 6 = false.
4 = False: Measures of central tendency, such as the mean, median, and mode, actually show the center or average of a set of data.
They do not provide information about how the data tends to move away from the center.
Measures of dispersion, such as the standard deviation or range, are used to assess the spread or variability of the data.
5 = True: Measures of central tendency are used to determine the center or typical value of a dataset.
The mean, for example, calculates the average of all the data points, while the median represents the middle value when the data is arranged in ascending or descending order.
The mode identifies the most frequently occurring value.
6 = False: "Inferential" statistics involves making inferences or drawing conclusions about a population based on information obtained from a sample.
It uses probability theory and sampling techniques to generalize findings from a smaller group (sample) to a larger group (population).
In essence, inferential statistics allows researchers to make educated guesses or predictions about a larger population based on the information gathered from a representative sample.

what is length ?
Length is a physical dimension that describes the extent of an object or distance between two points. In geometry, length refers to the distance between two points, and it is usually measured in units of length such as meters, centimeters, feet, inches,
In the given question,
(a) The correct trigonometric ratio to use in this problem is the sine ratio, which relates the opposite side to the hypotenuse in a right triangle. In this case, we are given the angle A and we want to find the length of the opposite side, which is the distance from the top of the ravine to Lucy. Therefore, we can use the sine ratio as follows:
sin(A) = opposite/hypotenuse
(b) We can set up the equation using the given information as follows:
sin(17°) = opposite/150
where opposite is the length of the repel line that we want to find.
(c) To solve for the length of the repel line, we can rearrange the equation as follows:
opposite = sin(17°) x 150
opposite = 0.2924 x 150
opposite ≈ 44
Therefore, the length of the repel line needed is approximately 44 feet (rounded to the nearest whole number).

Justin is 2years older than one third Marcellas age. Aimee is four years younger than 2 times Justin's age. Define a variable and write an expression to represent Justina age. Than find Justina age and aimees age if Marcella is 63 years old
Answers
Answer:
Justin is 23 years old, and Aimee is 42 years old.
Step-by-step explanation:
Let Marcella's age be represented by x, and Justin's age by t.
Given that Justin is 2 years older than one third Marcella's age.
t = \(\frac{1}{3}\) x + 2
t = \(\frac{x}{3}\) + 2 ........... 1
Also, Aimee is four years younger than 2 times Justin's age.
Aimee = 2 x t - 4
Aimee = 2t - 4 .......... 2
But, Marcella's age is 63 years, so that from equation 1;
Justin's age = \(\frac{x}{3}\) + 2
= \(\frac{63}{3}\) + 2
= 21 + 2
= 23
Justin is 23 years.
From equation 2,
Aimee = 2 x 23 - 4
= 46 - 4
= 42
Aimee is 42 years.
Therefore,
Marcella is 63 years old, Justin is 23 years old, and Aimee is 42 years old.

Answer:
The scatter plot would closely resemble a straight line with a positive slope, but causation cannot be determined.
Step-by-step explanation:
Recall that causation and correlation are 2 different things. Say Taller people usually had a name that started with the letter “A” It's a correlation, but a name does not determine the height, so it's not causation. (I took the test and got it right too.)
The data has a strong, negative correlation, and a causal relationship exists between the team playing at home and winning would be imply about the football team winning at home.
What is a correlation coefficient?It is an index that measures correlation between two variables, assuming values between -1 and 1.
If it is positive, the relation is positive, that is, they are direct proportional. If it is negative, they are inverse proportional.
If the absolute value of the correlation coefficient is greater than 0.6, the relationship is strong.
It also is the slope of the line of best fit.

Assume that Mr. A and Mr. B have the same utility function for a change, x, in their fortune, given by U ( x ) = x 1/3 . Suppose now that one of the two men receives, as a gift, a lottery ticket which yields either a reward of r dollars (r > 0) or a reward of 0 dollars, wi th probability ½ each. Show that there exists a number b > 0 having the following property: Regardless of which man receives the lottery ticket, he can sell it to the other man for b dollars and the sale will be advantageous to both men.
Answers
We can find a value of b such that each person would be willing to buy the lottery ticket from the other for that price, and the sale will be advantageous to both men.
We start by calculating the expected utility of the lottery for each person. Let U(x) be the utility function for a change x in fortune, and let r be the amount of the reward.
For Mr. A, the expected utility of the lottery is:
EU_A = ½U(r) + ½U(0) = ½r^(1/3)
For Mr. B, the expected utility of the lottery is the same:
EU_B = ½U(r) + ½U(0) = ½r^(1/3)
Now, we want to find a price b such that each person would be willing to buy the lottery ticket from the other for that price. Suppose that Mr. A is willing to pay b dollars to Mr. B for the ticket. Then Mr. A's expected utility from buying the ticket is:
EU_A(b) = ½U(r+b) + ½U(0-b) = ½(r+b)^(1/3) - ½(-b)^(1/3)
Similarly, if Mr. B is willing to pay b dollars to Mr. A for the ticket, then Mr. B's expected utility from buying the ticket is:
EU_B(b) = ½U(r-b) + ½U(0+b) = ½(r-b)^(1/3) - ½b^(1/3)
Now, we want to find a value of b such that both EU_A(b) and EU_B(b) are greater than or equal to EU_A and EU_B, respectively. That is, we want the sale to be advantageous to both men.
For Mr. A, we have:
EU_A(b) ≥ EU_A
½(r+b)^(1/3) - ½(-b)^(1/3) ≥ ½r^(1/3)
(r+b)^(1/3) + b^(1/3) ≥ r^(1/3)
Similarly, for Mr. B, we have:
EU_B(b) ≥ EU_B
½(r-b)^(1/3) - ½b^(1/3) ≥ ½r^(1/3)
(r-b)^(1/3) + b^(1/3) ≤ r^(1/3)
Now, we want to find a value of b that satisfies both inequalities. To do so, we first note that both sides of each inequality are non-negative, since r and b are both positive. Therefore, we can cube both sides of each inequality without changing the direction of the inequality. This gives:
(r+b) + 3b(r+b)^(1/3) ≥ r
(r-b) - 3b(r-b)^(1/3) ≤ r
Adding the two inequalities together, we get:
2r ≥ 3b[(r+b)^(1/3) - (r-b)^(1/3)]
Now, we can solve for b:
b ≤ 2r / 3[(r+b)^(1/3) - (r-b)^(1/3)]
This inequality shows that there exists a positive value of b that satisfies both inequalities since the right-hand side is a continuous function of b that goes to infinity as b approaches zero or r. Therefore, we can find a value of b such that each person would be willing to buy the lottery ticket from the other for that price, and the sale will be advantageous to both men.

The volume is 1239.33 unit³
What is Volume?Volume is a mathematical term that describes how much three-dimensional space an object or closed surface occupies. Volume is measured in cubic units like m³, cm³, in³, etc. Volume is sometimes referred to as capacity.
The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.
Given:
l= 11
w= 13
h= 18 + 8 = 26
Now, Volume of given solid

What is estimation?
To make calculations simpler and more realistic, estimation of a number refers to a plausible assumption of the actual value.
Estimation is the process of approximating a quantity with the necessary accuracy.
The result is quickly and roughly determined by rounding off the numbers used in the calculation.
To estimate the product, we first round off the multiplier and the multiplicand to the nearest tens, hundreds, or thousands and then multiply the rounded numbers.
