Answer:
no increase
Step-by-step explanation:
the range is the difference between the largest and smallest values in the data set.
largest value = 9 and smallest value = 3 , then
range = 9 - 3 = 6
replacing 8 by 5 has no effect on the above 2 values , so no change
Answer:
The range would stay the same.
Step-by-step explanation:
The old set is 6 9 3 6 8 6 3
- range is 9-3 = 6.
The new set is 6 9 3 6 5 6 3
which has a range of 9 - 3 = 6.

Sofia buys 3.8 pounds of potatoes for $0.85 per pound. Flynn buys 4.2 pounds of potatoes for $0.75 per pound.
How much more does Sofia spend than Flynn?
Answer:
Step-by-step explanation:
A. $0.08
Step-by-step explanation:
I would find out the total price of potatoes for each person:
Sofia: $0.85 x 3.8lb = $3.23
Flynn: $0.75 x 4.2lb = $3.15
To get the final answer, I would subtract to find the difference between the two prices.
$3.23 - $3.15 = $0.08
A cube pyramid has 7 at its base and 9.4 for its height what is the answer?
Answer:
Assuming this is volume, the answer is 153.33
Step-by-step explanation:
In a cube pyramid, the sides of the base are all the same, so if one side is 7, all of them are seven. To find the area of the base, the formula Area=Length x Width is used. Because the base is a square, the formula is simplified into Area=Side Length x Side Length. This gives us 49. The next step is to multiply this base times the height, 9.4, which is 460.6. However, this is the volume of a rectangular prism with those dimentions. A pyramid is a third of a rectangular prism. So, the answer is multiplied by 1/3, which is 153.33.

The area of the sector will be 59.19 ft². The area of a circle's sector is the portion of the area encompassed inside the sector's perimeter.
What is an area of the sector?The area of a circle's sector is the amount of space encompassed inside the sector's perimeter. The origin of a sector is always the circle's center.
The region of a circle encompassed by its two radii and the arc connecting them is known as the sector of a circle.
The area of a circle is found as;
A = πr²
A = π(7.2 ft)²
A = 162.78 ft²
The area of the sector is the ratio of the provided slope to the angle of the complete circle which is similar to 2π;
[tex]\rm A_S= (162.78 )\times \frac{8\pi }{11 \times 2\pi} = 59.19 \ ft^2[/tex]
Hence the area of the sector will be 59.19 ft².

The diagonals of quadrilateral EFGH intersect at D(1,3). EFGH has vertices at E(2,6) and F(-4,5). What must be the coordinates of G and H to ensure that EFGH is
a parallelogram?
Answer:
G(0, 0), H(6, 1)Step-by-step explanation:
The diagonals of a parallelogram bisect each other.
Point D is the midpoint of both diagonals.
Endpoint of EG is point G with coordinates (x, y):

(-4 + x)/2 = 1 ⇒ - 4 + x = 2 ⇒ x = 4 + 2 ⇒ x = 6(5 + y)/2 = 3 ⇒ 5 + y = 6 ⇒ y = 6 - 5 ⇒ y = 1H = (6, 1)Find the slope of the line containing the following points by using the slope-formula, below: (-3, 6) (5, -9)

Which equation best models the data shown on the scatter-plot below?
The scatterplot is an illustration of a linear regression.
The equation that best models the scatter plot is y = 4x+ 35
How to determine the equation of the scatterplot?The equation of a linear regression is represented as:
y = mx + b
Where:
m represents the slope
b represents the y-intercept
From the graph, we have the following points on the line of best fit (see attachment)
(x,y) = (10,75) and (20,105)
The equation is then calculated as:
[tex]y = (\frac{y_2 - y_1}{x_2 - x_1})(x -x_1) + y_1[/tex]
This gives
[tex]y = (\frac{105 - 75}{20- 10})(x -10) + 75[/tex]
Evaluate
[tex]y = 4(x -10) + 75[/tex]
Open the bracket
[tex]y = 4x -40 + 75[/tex]
Simplify
[tex]y = 4x+ 35[/tex]
Hence, the equation that best models the scatter plot is y = 4x+ 35

If the number of bacteria in a
colony doubles every 25 hours
and there is currently a population
of 10,000 bacteria, what will the
population be 75 hours Trom now?
Answer:
The population of 75 hours from now would be 40,000.
Step-by-step explanation:
The reason for this is because your initial number is 10,000 and when 25 hours pass by, your population would be 20,000. Another 25 hours pass by, and then your population would be 40,000. If you multiply 25 by 3, you will notice 75 hours have just passed, so your answer would be 40,000.

Answer:
y = 4x -16
Step-by-step explanation:
The equation of the parallel line can be written from the given x-intercept when we know its slope. The slope will be the same as that of the graphed line. It can be found using the slope formula with the marked points (-3, -3) and (-1, 5).
m = (y2 -y1)/(x2 -x1)
m = (5 -(-3))/(-1 -(-3)) = 8/2 = 4 . . . . . slope of the lines
The point-slope equation for the line with slope 4 through point (4, 0) will be ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
y -0 = 4(x -4) . . . . line with slope 4 through the given x-intercept
y = 4x -16 . . . . . . expanded to slope-intercept form
