The average daily change in temperature will be 3 degrees The temperature dropped to 24 degrees in 8 days
Since we know an average could be a single number taken as an agent of a list of numbers, as a rule, the whole of the numbers divided by how numerous numbers are within the list. We are said the temperature dropped to 24 degrees in the 8 days
So the average of it will be =24 /8 = 3, which means the temperature needed to drop for at least 3 degrees in order to get the sum of 28 in 8 days.

Rewrite the point-slope form equation into slope-intercept form.
y+4= -3(x-5)
The slope-intercept form of the equation is
(Type an equation. Use integers or fractions for any numbers in the equation.
The point slope and the intercept form is y = -3x + 11
What is the slope intercept form?One of the most popular ways to represent a line's equation is in the slope intercept form of a straight line. When the slope of the straight line and the y-intercept are known, the slope intercept formula can be used to determine the equation of a line ( the y-coordinate of the point where the line intersects the y-axis).
This written in the form of y = ax + b
where a is the slope and b is the intercept
We have the equation as
y + 4 = - 3 ( x - 5 )
we would have to open the bracket and then take the like term
this is going to be
y + 4 = -3x + 15
From here we would get the like term
y = -3x + 15 -4
y = -3x + 11
The slope is -3 and the intercept is 11.

What’s Question 6 and 7 ?
Step-by-step explanation:
6.
the factors need to be zero for the x-intercepts.
but (-3 - 3) = -6 and not 0.
the same for (-7 - 7) = -14 and not 0.
his mistake was the signs.
what do I need to add to -3 to get 0 ? 3. and 7 to -7.
so, the correct f(x) is
f(x) = (x + 3)(x + 7)
to get x-intercepts at -3 and -7.
7.
in the same way we get the factors here : for a given x the y value has to be 0.
how is y turning 0 for a polynomial in factor form ? well, at least one of the factors has to be 0.
therefore, for (-6, 0) the factor has to be
(x + 6) as -6 + 6 = 0
for (2, 0) the factor has to be
(x - 2) as 2 - 2 = 0
pick one of them as your answer. they are both correct factors for f(x).

The given condition needs the following function;
Data Integration Error:
Data from a single source, obtained and entered in the same way across time is unusual to be present in a database of significant size and age. A database frequently comprises data that has been gathered over time from various sources using various ways. As an illustration, consider how the meaning of "affected" is evolving or changing as the crisis progresses and the number of people affected is tracked over time. In addition, many databases evolve in practice by joining together different pre-existing databases. Almost always, the databases involved in this merging effort include discrepancies involving various data units, measurement intervals, formats, etc. Any process that combines data from various sources has the potential to make mistakes. When two or more databases are combined, errors will be found where there are discrepancies between the databases as well as new errors will be produced (i.e. duplicate records). A few potential origins and types of errors in a big assessment are shown in Table 1 below, at three fundamental levels: after completing the survey, when adding information to the database, and when conducting the analysis.
So, we use " COUNTA "

Answer:
No solution (0 = 1)
Step-by-step explanation:
Given equation,

One angle of an isosceles triangle measures 80°. What measures are possible for the other two angles? Choose all that apply.
80°,20° or 50°,50° are possible for the other two angles.
Given:
One angle of an isosceles triangle measures 80°.
we assumed that the 80° is one of the equal angles, then there is another 80° angle.That makes 160°.
Since a triangle always totals 180°,
180° - 160° = 20°.
if the 80° was the only different angle instead,the two remaining angles total:
180 - 80 = 100
Since we have two identical angles remaining, we need only divide the 100° in half to get the final answer:
100/2 = 50°.
Therefore 80°,20° or 50°,50° are possible for the other two angles.

each day for four days, linda traveled for one hour at a speed that resulted in her traveling one mile in an integer number of minutes. each day after the first, her speed decreased so that the number of minutes to travel one mile increased by 5 minutes over the preceding day. each of the four days, her distance traveled was also an integer number of miles. what was the total number of miles for the four trips
The total number of miles for the four trips is 25 miles.
Given that;
Linda traveled for one hour each day for four days at a speed that made her cover one mile in an even number of minutes. After the first day, she started to lose speed, and it took her 5 minutes longer to complete a mile than the day before. Her journey distance was also an integer amount of miles throughout the four days.
We know that,
Distance is a product of speed and time. We need to find the distance here with the use of the given conditions, time is 1 hour.
Speed = Distance / Time
Hence, speed is 1 mile per x minutes because we want to distance by multiplying the time and speed together yielding 60 min * 1 mile / x mins.
Minutes cancel out, so now we have 60/x as our distance for the first day.
The distance for the given case;
⇒ [tex]\frac{60}{x},\frac{60}{x+5},\frac{60}{x+10},\frac{60}{x+15}[/tex]
It is given that x = 5;
⇒ [tex]\frac{60}{5},\frac{60}{10},\frac{60}{15},\frac{60}{20}[/tex]

The length of a rectangle is 5 yd longer than its width.
If the perimeter of the rectangle is 70 yd, find its length and width
Answer:
length is 20 yards, width is 15 yards
Step-by-step explanation:
Length = width + 5
2(W + 5) + 2(W) = 70
2W + 10 + 2W = 70
4W + 10 = 70
4W = 60
W = 60 ÷ 4
W = 15 yards
L = 15 + 5

The area of hexagon is found to be 18 square units by using the giving conditions.
What is the equation for calculating a hexagon's perimeter?P = 6a, where an is the length of one of its sides, is the formula for a regular hexagon's perimeter. Here, the hexagon's interior angles are all 120 degrees.
How do you calculate a hexagon's area?The formula for calculating the area of a hexagon is derived from the formula for calculating the area of an equilateral triangle since a regular hexagon is made up of six equilateral triangles. The formula for calculating a hexagon's area is 6([tex]\sqrt{3}[/tex]/4)a² where a is the regular hexagon's side length.Given: The perimeters of an equilateral triangle and a regular hexagon are equal.
We need to find the area of the hexagon.
Let,
x = side of trainagle
a = side of hexagon
3x = 6a
x = 2a
Area of equilateral triangle = ([tex]\sqrt{3}[/tex]/4)x² = 12 square units
Area of hexagon is given as follows:
= 6([tex]\sqrt{3}[/tex]/4)a²
= (6[tex]\sqrt{3}[/tex]/4)(x²/4)
= 12(6)/4
= 18 square units
