The daily high temperatures, in degrees Celsius, for two weeks were recorded. The first week had a mean high temperature of 8 degrees Celsius and a mean absolute deviation (MAD) of 1 degree Celsius. Here is a list of the high temperatures, in degrees Celsius, for the second week. A. What is the mean temperature for the second week? B. What is the mean absolute deviation for the second week? C. Which week had greater variability in high temperature? Explain your reasoning. (When necessary, round all answers to the nearest hundredths place. Type all answers below.
Answer:
(A) The mean temperature for the second week is 4.86 degrees Celsius.
(B) The mean absolute deviation for the second week is 4.86 degrees Celsius.
(C) The second week had greater variability in high temperature.
Step-by-step explanation:
We are given that the daily high temperatures, in degrees Celsius, for two weeks were recorded. The first week had a mean high temperature of 8 degrees Celsius and a mean absolute deviation (MAD) of 1 degree Celsius.
Here is a list of the high temperatures, in degrees Celsius, for the second week;
5, 9, 7, 0, 3, 5, 5
(A) The mean temperature for the second week is given by;
Mean = [tex]\frac{\text{Sum of all data values}}{\text{Total number of values}}[/tex]
= [tex]\frac{5+9+7+0+3+5+5}{7}[/tex]
= [tex]\frac{34}{7}[/tex] = 4.86 degrees Celsius
(B) Mean absolute deviation for the second week is calculated as;
Firstly, subtracting mean from each data value;
| 5 - 4.86 | = 0.14
| 9 - 4.86 | = 4.14
| 7 - 4.86 | = 2.14
| 0 - 4.86 | = 4.86
| 3 - 4.86 | = 1.86
| 5 - 4.86 | = 0.14
| 5 - 4.86 | = 0.14
Now, we will find the mean of these deviations;
Mean absolute deviation = [tex]\frac{0.14+4.14 + 2.14+4.86+1.86+0.14+0.14}{7}[/tex]
= [tex]\frac{13.42}{7}[/tex] = 1.92 degrees Celsius
(C) The second week had greater variability in high temperature because it's mean absolute deviation is greater than that of first week. And also the mean absolute deviation tells us that on average how far the data values are from the mean.
Karis receives $90000 per year working as a manager. She spends 15% every 3 month on her daughters college tuition. Write a function rule for the amount of money that Karis still has as a function of time in month
Answer:
[tex]f(m) = 90000 - 0.05m[/tex]
Step-by-step explanation:
Given
[tex]Base\ Amount = \$90000[/tex]
[tex]Spending = 15\%[/tex] -- every 3 months
Required
Determine the function that shows her monthly balance:
Represent month with m
If she spends 15% every 3 months;
Then
She spends 5% every month
i.e.
[tex]monthly = \frac{15\%}{3}[/tex]
[tex]monthly = 5\%[/tex]
If [tex]1\ month = 5\%[/tex]
Then
[tex]m\ months = 5\% * m[/tex]
Monthly balance (f(m) is then calculated as:
[tex]f(m) = Base\ Amount - Monthly\ Spending[/tex]
[tex]f(m) = 90000 - 5\% * m[/tex]
[tex]f(m) = 90000 - 0.05 * m[/tex]
[tex]f(m) = 90000 - 0.05m[/tex]
Bob and Carl each rented the same kind of moving truck from EZ Move. There was a flat rental fee plus a charge per mile that the truck was driven. Bob's cost for his truck was $112.96 for 138 miles. Carl's cost for his truck was $142.78 for 209 miles. Which equation can be used to represent the cost of the rental truck? Round to the nearest hundredth if necessary. y = 71 x minus 29.82 y = 25 x minus 66 y = 0.42 x + 71 y = 0.42 x + 55
Answer:
D. y = 0.42x + 55
Step-by-step explanation:
Let the equation for the cost of the truck be represented by y = mx + b,
where y = cost of truck per mile, x = number of miles, m = charge of the truck per mile and b = rental fee.
We are given that,
Cost for Bob's truck ( y ) = $112.96 for x = 138 miles, and
Cost for Carl's truck ( y ) = $142.78 for x = 209 miles.
This gives us the equations,
142.78 = 209m + b
112.96 = 138m + b
Subtracting these equations, we get,
29.82 = 71m
i.e. m = 0.42
Substituting the value of ' m ' in first equation, we get,
142.78 = 209 × 0.42 + b
i.e. 142.78 = 87.78 + b
i.e. b = 55.
Hence, the equation for the cost of the truck is y = 0.42x + 55
Answer:
d.y = 0.42 x + 55

If m∠A = m∠B and m∠A + m∠C = ∠D, then m∠B + m∠C = ∠D Which property is shown?
Answer:
Substitution Property
Step-by-step explanation:
So we know that:
[tex]m\angle A=m\angle B[/tex]
And we also know that:
[tex]m\angle A+m\angle C=\angle D[/tex]
And by using a specific property, we get that:
[tex]m\angle B+m\angle C=\angle D[/tex]
Essentially, we substituted B for A.
So, this is an example of the substitution property, where if two sides/angles are congruent, we can substitute them for each other.

2x-4xy+5x-2xy-4x-4y?
Answer: 3x-6xy-4y
Step-by-step explanation: So, it’s been a few years since I’ve been in high school, but if I remember correctly...it should break down as such...
A good method to breaking this down is to use parentheses to break up the equation.
Example: (2x)(-4xy)(+5x)(-2xy)(-4x)(-4y)
Keep in mind we are only using the parentheses as a breaker and not as multiplication as it can be seen.
So, start with the singular ‘x’ variants. (2x) (+5x) (-4x). 2x+5x is 7x. 7x-4x is 3x. Now, move onto ‘xy’ variant. (-4xy) and (-2xy). As these are both negative, they add together to make an even lower number...being -6xy. Onto the final step taking the singular ‘y’ variant. There’s only 1 ‘y’ variant so it just stays -4y.
In the end, you end up with 3x-6xy-4y. :) Hope this helps. If you have any more questions, let me know!

ASAP HELPPP !!!!Which of the following statements best describes a linear pair? A linear pair consists of complementary angles. A linear pair consists of supplementary angles. A linear pair consists of nonadjacent angles. A linear pair consists of vertical angles.
Answer:
A linear pair consists of supplementary angles
Step-by-step explanation:
Because a linear pair is 2 lines that form an 180 degree angle.
The statement that best describes a linear pair is that A linear pair consists of supplementary angles. The correct option is B.
What is Supplementary Angle?When the sum of two angles measures up to 180° then these angles are known as supplementary angles of each other.
for example, ∠x + ∠y = 180°, therefore, the ∠x and ∠y are the supplementary angles of each other.
If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two angles are two pairs of linear angles. That means, that if linear angles are aligned adjacent to each other, their exterior sides will make a straight line.
Further, since the angle at any side of a line is 180°. Therefore, the sum of these two angles will be equal to 180°.
Hence, the statement that best describes a linear pair is that A linear pair consists of supplementary angles.

He repartido mi colección de canicas entre mis tres amigos. A thales le he dado 1/5 del total, a arquimedes un 1/3 del resto y por último a pitagoras le he regalado las 16 canicas que me quedaban
Answer:
Ok, supongamos que en total hay N canicas.
1/5 de esas canicas se le dieron a Thales.
Entonces el resto ahora es:
1 - 1/5 = 4/5.
1/3 de esas canicas se le dieron a Arquimedes.
Entonces Arquimedes recibe:
(1/3)(4/5) = 4/15 de las canicas totales.
El resto, que eran 16, se le dieron a Pitagoras.
Ahora, las dos primeras entregas fueron:
1/5 + 4/15 = 3/15 + 4/15 = 7/15.
El resto seria:
1 - 7/15 = 8/15.
Y sabemos que el resto es igual a 16 canicas, entonces tenemos que:
(8/15)*N = 16.
De aca podemos calcular el numero total de canicas.
N = 16*(15/8) = 30
Esto quiere decir que inicialmente hay 30 canicas.
Thales recibe 30*(1/5) = 7 canicas.
Arquimedes recibe 30*(4/15) = 8 canicas.
Pitagoras recibe 16 canicas.

Divide. 5892 ÷ 18 in fraction form.
Answer: mixed number 327 1/3
Step-by-step explanation:
5892/ 1÷18/ 1=327 1/3
put each number over one to turn it into a fraction.
The answer in fraction form is 982/3 or 327 (1 / 3).
Given,
5892 ÷ 18
We need to divide it in fraction form.
How do we divide a fraction?Suppose we have two fractions:
a/b and c/d
Divide a/b by c/d
Now,
a/b ÷ c/d
a/b x d/c
Divide 5892 ÷ 18 in fraction form.
Write 5892 and 18 in fraction form:
- 5892/1
- 18/1
Now,
= 5892 / 1 ÷ 18/1
= (5892/1) / (18/1)
= (5892/1) x (1/18)
= (5892 x 1) / (1 x 18)
= 5892 / 18
Write it in 6 multiples
= (6 x 982) / (6 x 3)
6 gets cancelled
= 982 / 3
We can write it in mix fraction.
= 327 (1 / 3)
Since,
3 x 327 = 981
981 + 1 = 982
Thus the answer in fraction form is 982/3 or 327 (1 / 3).

Determine if the following relation represents a function or not.
{(2,3), (4,3), (6,3), (5,9), (3,9)}
Answer:
It is a function.
Step-by-step explanation:
Functions are relations in which one domain value is assigned to exactly one range value. The x-value must not repeat in the relation set for it to be a function.
{(2,3), (4,3), (6,3), (5,9), (3,9)}
There are no repeating x-values given.
The relation should be a function.
Hope this helps.
Functions are relationships where a single domain value is allocated to a single range value precisely. For a relation set to be a function, the x-value cannot repeat.
What is a Set?The simplest definition of a set in mathematics is a grouping of unique items. Any collection of elements, such as a group of numbers, hours of the week, different kinds of automobiles, etc., might be considered a set.
A set's elements are all the items that make up the set.
As per the given data in the question,
