The 6 AM temperatures for four consecutive days in town of Lincoln were -12.1°C, -7.8°C, -14.3°C, and -7.2°C. What was the average 6 AM temperature for the four days
Answers
Answer:
- 10.35°C
Step-by-step explanation:
Given that :
Temperature at 6 AM for four consecutive days :
X : -12.1°C, -7.8°C, -14.3°C, and -7.2°C
The average temperature :
ΣX / n
n = sample size = number of days = 4
[(-12.1) + (-7.8) + (-14.3) + (-7.2)] / 4
= - 41.4 / 4
= - 10.35°C
Hence, the average 6 AM temperature for the four days is - 10.35°C
What is the complete factorization of x^2 + 2x − 63?
A. (x + 21)(x − 3)
B. (x − 9)(x + 7)
C. (x + 9)(x − 7)
D. (x − 21)(x + 3)
Answers
Answer:
C. (x+9)(x-7)
Step-by-step explanation:
(x*x)=x^2
(9*x)=9x
(-7*x)= -7x
(9*-7)= -63
x^2+9x-7x-63 = x^2+2x-63

The statement that describes the relationship is that There is an association because the relative frequencies by column are different.
What are relative frequencies?It represents how the particular event arise within the overall number of observations. It is the frequency- time that used the percentage, fractions, and even proportions.
So based on this, we can say that The statement that describes the relationship is that There is an association because the relative frequencies by column are different.

Which function increases at a faster rate on 0 to infinity
fo= Zorg) = 22? Explain your reasoning
Answers
Answer:
f(x) = x² increases at a faster rate than g(x) = 2x.
f(x)
Reason:
x = 0, 1, 2, 3, 4, 5, 6, 7
f(x) = 0, 1, 4, 9, 16, 25, 36, 49
g(x) = 0, 2, 4, 6, 8, 10, 12, 14.
Comparing the values of f(x) and g(x), we can see that that of f(x) are far higher than that of g(x) for the same values of x.
So f(x) increases at a faster rate.

Point G is in love segment FH give an FH equals 4XGH equals XNFG Eagles 2X +10 determine the numerical link of FG
Answers
Answer:
FG= 30
Step-by-step explanation:
Point G is on line Segment FH
Given
FH= 4x
GH= x
FG= 2x+10
If the point G is on the line FH then the total of the two line segement FG and GH must be equal to FH
FH= FG+ GH
Putting the values in the above equation:
4x= 2x+10+x
4x= 3x+10 Solving for x
10= 4x-3x
10= x
FG= 2x +10
FG = 2(10) +10 Putting the value of x
FG= 20+10
FG= 30
Check :
FH= 4x= 4(10)= 40
GH= x= 10
FG = FH- GH= 40-10= 30

The picture below shows a pole and its shadow:
A pole is shown with a right triangle side. The right triangle has hypotenuse 221 cm and base 21 cm.
What is the height of the pole?
121 centimeters
220 centimeters
225 centimeters
Answers
Answer:
the height of the pole is 220 centimeters
Step-by-step explanation:
The computation of the height of the pole is shown below
Here we applied the pythagoras theorem
Given that
Hypotenuse = 221 = c
And, base = 21 cm = b
a^2 + b^2 = c^2
So, the height is
= 21^2 cm - 221 cm
= 441 cm - 221 cm
= 220 cm
Hence, the height of the pole is 220 centimeters

Determine which points are valid solutions and which are invalid, and then drag them to the correct location on the table.
Answers
Answer:
Valid is (32,12) , (6,36) , (20,20)
Invalid is (-4,40) , (36,-8), (15,22.5)
Step-by-step explanation:
I just got it right on edmentrum
Answer:
Valid solutions
(20,20)
(32,12)
(6,36)
Invalid solutions
(-4,40)
(36,-8)
(15,22.5)
Step-by-step explanation:
First, plot each point on the graph to determine whether it lies in the solution set.
All the points lie within the shaded region, so they are all solutions to the inequality.
Now, consider restrictions to the domain and range. Since x is the number of wallets and y is the number of hats, each x- and y-value must be a positive whole number. That leaves only the following points as valid solutions.
(20,20)
(32,12)

Step-by-step explanation:
The function defined that the output of the function can be determined by multiplying the input by 2 and adding 5.
i.e.
if input = x, then output = 2x+5
We are given
Inputs:
-1, 0, 1/2 and 3
Thus,
When input x = -1, then output = 2(-1) + 5 = -2+5 = 3
When input x = 0, then output = 2(0) + 5 = 0 + 5 = 5
When input x = 1/2, then output = 2(1/2) + 5 = 1 + 5 = 6
When input x = 3, then output = 2(3) + 5 = 6 + 5 = 11
Therefore, the required table is:
Input Output

Revathi reached her grandparents' place at 9:20 a.M. After travelling in a train for 9 hrs and 37 mins. What time did her train start from the station?
Answers
Answer:
Starting time = 11:43 pm last night
Step-by-step explanation:
The time that her train started from the station is as follows
Given that
Grandparents reached the place at 9:20AM
The travelled time is 9 hours and 37 mins i.e. 9:37 hours
Starting time = Reached time - journey time
Starting time = 9:20 am - 9:37 hrs
= 11:43 pm last night
