Given that,
The number of heating degree days can be calculated by the formula H = 65 - T, where 65 is degrees Fahrenheit, and T is the average of the high and low temperatures for the day.
Solution,
The high temperature was 51°F and the low temperature was 45°F.
Average of high and low temperatures for the day is given by :
[tex]T=\dfrac{51+45}{2}\\\\T=48^{\circ} F[/tex]
Now using formula :
H = 65 - T
H = 65 - 48
H = 17
Hence, there are 17 heating degree days.

Which graph represents f(x) = -2x^4
Answer:
Top right
Step-by-step explanation:
Because it is negative and that is the typical shape for x^4 functions
The graph represents the given function f(x) is attached below
Top right option graph is correct
Given :
The equation of a graph is given by
[tex]f(x)=-2x^4[/tex]
Lets look at the end behavior of the given function f(x)
The leading coefficient is negative that is -2
The highest exponent is 4 that is the degree is even
When the leading coefficient is negative and degree is even then the graph goes down on both sides
As x-> ∞, f(x)-> -∞
As x-> -∞, f(x)-> -∞
So , the graph on the top right is correct
I will attach the graph

Prove: m∠3 + m∠1 + m∠2 = 180
(2)Write a paragraph, flowchart or, 2 column proof for the following conjecture:
Given: ∠1≅∠4
Prove: ∠3≅∠2
Answer:
Because it is given that q ║ r and r ║ s, then q ║ s by the TRANSITIVE PROPERTY OF PARALLEL LINES. This means that 1 2 because the CORRESPONDING

The graph of a line passes through the two points (-2,1) and (2,1).
part 1
Graph the line through the two points (-2,1) and (2,1). Based on the graph of the line only, determine the slope and y-intercept of the line.
part 2
write the equation, in slope-intercept form, of the line that passes through the points (-2,1) and (2,1)
complete your work in the space provided or upload a file that can display math symbols if your work requires it. be sure to include all of the answers for part 1 and 2
Answer:
see below
Step-by-step explanation:
part 1
(-2,1) and (2,1)
Both points have the same y value
The slope is zero since it is a horizontal line and it crosses the y axis at y =1 so the y intercept is (0,1)
part 2
The equation of the line in slope intercept form is
y= mx+b where m is the slope and b is the y intercept
y = 0x+1
y =1

A basketball team played six games. In those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13. What was the mean difference in game scores over the six games?
Mean =sum of observations/ no.of observations
Mean=8+11+7+11+4+13/6
=54/6
mean=9
The mean difference in the game scores over six games is 2.5
What is mean difference?The mean difference measures the absolute difference between the mean value in two different groups.
Given is a basketball team which played six games such that in those games, the team won by 8 points, lost by 11, won by 7, won by 11, lost by 4, and won by 13 respectively.
The mean difference of the given data can be calculated using the following formula -
Mean Difference = (∑W / n) - (∑L / n)
Where -
(∑W / n) is the mean of games won.
and
(∑L / n) is the mean of games lost.
(∑W / n) = (8 + 7 + 11 + 13)/4 = 9.75
and
(∑L / n) = (11 + 4)/2 = 15/2 = 7.5
Mean difference = (∑W / n) - (∑L / n) = 9.75 - 7.5 = 2.5
Therefore, the mean difference in the game scores over six games is 2.5

-2.25x+8.75x+10-20 solve x pls
Answer:
im gonna assume the 10 - 20 is what the equation is = to if not x wouldnt be = to anything x = -1.5
Step-by-step explanation:
-2.25x + 8.75x = 10-20
-2.25x+ 8.75x = -10
6.50x = -10 divide both sides by 6.5
x = -1.5
Jessica bought 4 packages of birthday invitations for 16.95 per package including tax each package contained 12 birthday invitations one stamp coast 0.44 she plans to split the cost evenly with her mother how much money will Jessica mother need to give to Jessica
Answer:
Jessica's mum will give her 44.46
Step-by-step explanation:
To solve this, we will first of all need to get the total cost of sending the birthday invitations across. After that, we can now split the cost into two.
Cost of sending birthday invitations:
Package cost = 16.95
Number of packages bought = 4
total sum spent on packages = 4 X 16.95 = 67.8
Each package contains 12 invitations.
There are 4 packages.
Total number of invitations = 12 X 4 = 48 invitations
One stamp cost 0.44.
Putting stamps on all 48 invitations will cost 0.44 X 48 = 21.12
Therefore the total cost will be the total sum spent on packages +the total sum spent on stamps = 67.8 + 21.12 = 88.92
Her mum has agreed to pay half of this cost which is 88.92 / 2 = 44.46

A student pushes a the same cart with the same 50N of Force over the same distance of 10m, but on this occasion was timed in 5s by their parents who were in a hurry to get home. What was their power? *
Answer:
100W
Step-by-step explanation:
Power = Work done / time
Work done = force × distance
given,
force = 50Ndistance = 10mtime = 5sWork = 50 × 10
Work = 500J
Power = 500 / 5
Power = 100W

What is the image point of (4,5) after a translation left 5 units and down 3 units?
Answer:
(-1,2)
Step-by-step explanation:
Going left means the x value goes down. In this case, it went to the left 5 spaces. so, all you have to do is subtract 5 from 4 which is -1. When going down on a graph, the y value goes down as well. Subtract 3 from 5 and you get 2. Therefore, the answer is (-1, 2).

Alina is 6 years older than Greg. Amy’s age is 2.5 times Alina's age. Amy is 40. How old is Greg?
A. 16
B.10
C. 15
D.10
Answer:
Hi friend! The answer is D. 10
I hope this helps!
Answer:
B) 10
Step-by-step explanation:
Assign variables to each person:
A=Alina's Age
M=Amy's Age
G=Greg's Age
Set up a system of equations given the information:
A=6+G
M=2.5A
M=40
Notice that M is already given, so we can plug that into the second equation:
40=2.5A
16=A
So Alina is 16 years old, but the problem asks for Greg's age, so we plug Alina's age in the first equation:
16=6+G
10=G
So Greg is 10 years old, therefore B is the correct answer.
