Using the concepts of the mean and of the mean absolute deviation, the correct option is given as follows:
Last month, the amount of rain that fell each day varied less than the month before.
What is the mean absolute deviation of a data-set and what does it represent?The mean of a data-set is given by the sum of all observations divided by the cardinality of the data-set, which is the number of observations in the data-set.The mean absolute deviation of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations, hence it basically is the mean of the deviations, given a degree of variability.The mean absolute deviation(MAD) represents the average by which the values differ from the mean.In this problem, we have that:
Two months ago, the measures were: Mean 9.4 cm, MAD 3.5 cm.Last month, the measures were: Mean 11.5 cm, MAD 1.6 cm.Due to the lower mean absolute deviation combined with the higher mean, the amount varied less than the month before, hence the last option is correct.

Answer:
m<1 = 159˚
m<2 = 21˚
m<4 = 21˚
Step-by-step explanation:
Angle one is a vertical angle to angle 3 so they have the same angle. Angle 2 and 4 are adjacent angles to angle 3, so they are supplementary angles with angle 3, which 180-159 = 21˚.
Help with this problem please :)
The value of the unknown angle is as follows:
m∠BGF = 80 degreesHow to find angles?An angle bisector or the bisector of an angle is a ray that divides an angle into two equal parts
Therefore, CH bisects ∠GCD.
Therefore, it divide ∠GCD into two equal halves.
GC bisect ∠BGD.
Therefore, it divides ∠BGD into two equal halves.
Hence,
m∠BGC = m∠CGF
Therefore,
m∠BGC = 7x - 2
m∠CGF = 8x - 8
7x - 2 = 8x - 8
7x - 8x = -8 + 2
-x = -6
x = 6
Therefore,
m∠BGF = 7x -2 + 8x - 8
m∠BGF = 15x - 10
m∠BGF = 15(6) - 10
m∠BGF = 90 - 10
Therefore,
m∠BGF = 80 degrees

a equals negative 2 over 21
a equals 2 over 21
Value of 'a' for the given statement the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.
As given in the question,
Given statement :
Negative a minus four sevenths equals two thirds for a
Represent the statement in equation form :
-a -(4 / 7) = ( 2 / 3 )
Solve by adding both the side ( 4 / 7 ) we get,
-a - (4 /7) + (4 /7) = (2/3) +(4/7)
⇒ -a = (2/3) + (4/7)
least common multiple of 3 and 7 is 21.
-a = ( 14 /21) + (12 /21)
⇒ -a = 26 /21
⇒ a = -26/21
Therefore, value of 'a' for the given statement the negative a minus four sevenths equals two thirds for a after solving is equal to negative 26 over 21.

today, the waves are crashing onto the beach every 4.8 seconds. the times from when a person arrives at the shoreline until a crashing wave is observed follows a uniform distribution from 0 to 4.8 seconds. round to 4 decimal places where possible.
A person will wait at least 1.8720 seconds before the wave crashes when the waves are crashing onto the beach every 4.8 second
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 lower than x is given by the following formula.
[tex]P(X\leq x)[/tex] = x-a / b-a
Uniform distribution from 0 to 4.8 seconds.
This means that a=0 , b=4.8
61% of the time a person will wait at least how long before the wave crashes in?
This is the 100 - 61 = 39% percentile, which is x for which [tex]P( X\leq x)= 0.39[/tex] . So
[tex]P(X\leq x)= \frac{x-a}{b-a}[/tex]
x= 1.8720

In two or more complete sentences, describe the transformation(s) that take place on the parent function to achieve the graph of g(x)=log(-3x-9)+1.
Answer:
Logarithmic functions are the inverses of exponential functions. The logarithmic function y=log(x) is called the logarithmic function with base a .
When a constant c is added to the input of the parent function f(x)=loga(x), the result is a horizontal shift c units in the opposite direction of the sign on c. Our function is shifted 3 units to the right.
It is shifted 2 units vertical.(2 units down).

A car rental advertised a car for $27.95 per day and $0.26 per mile. If someone rents the car for 4 days how many whole miles can he drive in a $150 budget
(Round down to the nearest whole mile)
The number of miles he/she can drive with a budget of 150 dollars is 469 miles.
How to find the number of miles he can drive?The car rental advertised a car for $27.95 per day and $0.26 per mile.
If someone rents the car for 4 days and he has a budget of 150 dollars, the number of miles he can drive can be calculated as follows:
The equation used to represent the situation is as follows:
let
x = number of miles drove
Therefore,
150 = 27.95 + 0.26x
subtract 27.95 from both sides of the equation
150 - 27.95 = 27.95 - 27.95 + 0.26x
0.26x = 122.05
divide both sides by 0.26
x = 122.05 / 0.26
x = 469.423076923
x = 469 miles
Therefore, the number of miles he can drive is 469 miles.

water flows at a constant rate. Kian measures 8 cups in 6 seconds. whats the constant of proportionality of cups of water to minutes
The constant of proportionality in cups of water to minute is 80 cups/min
What is the constant of proportionality in cups per minute?Here we have the proportional relation:
y = k*x
Where y is the number of cups and x the time in seconds, then:
y/x = k
Replacing the values we know:
y = 8 cups.
x = 6 seconds.
We can get the value of k, the constant of proportionality, but first, let's write the time in minutes.
x = 6 seconds
remember that 1 min = 60 sec, then:
6 sec = (6/60) min = 0.1 min
So the constant of proportionality is:
k = 8cups/0.1 min = 80 cups/min

Let the function P be defined by p(x)=6n^2-4n-16 where (n-2) is a factor. To rewrite the function as a product of two factors, long devision was used.
The relation of the function as a product are found for the long division as: (n-2)×(6n - 16) + 0 = 6n² - 4n - 16
What is referred as the long division?Long Division is a technique for dividing large numbers that divides the problem into several steps that follow a sequence. Just like in frequent division problems, a dividend is divided by divisor, yielding the quotient and, in some cases, a remainder.Each component of a division equation has its own name.Dividend: The dividend is really the number divided during the division process.Divisor: The divisor is the number whereby the dividend is divided.Quotient: A quotient is an outcome of the division process.Remainder: We can't always divide things exactly. There could be an extra number. The leftover number is known as the remainder.The following describes the relationship between such four parts:
Divisor x Quotient + Remainder = Dividend
From the given pictures write the value of each part;
Dividend = 6n² - 4n - 16
Divisor = (n-2)
Quotient = 6n - 16
Remainder = 0
Thus, the relation becomes;
(n-2)×(6n - 16) + 0 = 6n² - 4n - 16
Thus, the relation of the function as a product are found for the long division.

A college student completed some courses worth 3 credits and some courses worth 4 credits. The student earned a total of 65 credits after completing 21 courses
How many 3 credit courses did the student complete?
How many 4 credit courses did the student complete?
Based on the fact that there are courses with 3 credits and 4 credits, with the total that a student can earn being 65 credits, the number of 3 credit courses that the student completed was 19 courses and the number of 4 credit courses was 2 courses.
How to find the number of courses?Assuming that the number of courses worth 3 credits are denoted as x and the number of courses worth 4 credits are denoted by y, the system of equations would be:
3x + 4y = 65
x + y = 21 courses
Using substitution for y gives:
x + y = 21
y = 21 - x
The number of courses with 3 credits is:
3x + 4y = 65
3x + 4(21 - x) = 65
3x + 84 - 4x = 65
84 - 65 = 4x - 3x
1x = 19
x = 19 courses

(allie buys her chocolate chips in bulk and can measure them to the nearest ounce.)
With the help of the ratio, we can conclude that Allie needs 42.72 ounces of chocolate chips for her new recipe.
What is the ratio?A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a bowl of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six.
