Jeff drew a line through (0, 0) and (7, 7) and said it was the line of best fit for the data.
Part A: Explain why Jeff's line is NOT the best fit.
Part B: What would be a better line of best fit for the scatter plot?
Part C: How does the actual line of best fit compare with Jeff's line?
Answers
Answer:
The line of best fit would not be right because there would be a big gap of space. The line should be the cooardinate 7,3 as this covers the line and the cooardinate 7,7 is an outlier. The new line is more accurately placed
Step-by-step explanation:
Answer:
The actual line of best fit would be from (0, 0) to (7, 4), this is because it covers majority of the points. All the other points are just anomalies. Moreover, Jeff's line is NOT the line of best fit because it is not accurate and is out of place. Furthermore, the actualy line of best fit is 3 places lower on the y-axis then Jeff's line of best fit.

P.S - The exact question is -
Given - Mr. Sanders wants to display his American flag in a triangular case as shown below.
To find - What is the area of the triangular case ?
Proof -
Given that,
Base of triangle = 14 2/5 in
Height of triangle = 8.5 in
We know that,
Area of triangle =1/2 *base *height =1/2 *8.5 *14 2/5
=1/2 * 8.5 * 14.4
=1/2 * 122.4
=61.2
we get
The area of the triangular case = 61.2 square inches

A right rectangular prism has a length of 2 ½ feet, a width of 3 feet, and a height of 1 ½ feet. Unit cubes with side lengths of ½-foot are added to completely fill the prism with no space remaining. What is the volume, in cubic feet, of the right rectangular prism?
Answers
Answer:
n=90
Step-by-step explanation:
As I think it is easy to answer the volume of prism I will also calculate no of small prism that can fit inside the larger one
so volume = length * width * height
volume of larger prism
vp=45/4 ft^3 =11.25
volume of small cubes
vs=1/2*1/2*1/2
vs=0.125 ft^3
now numbers of cube that can fit
n=vp/vs
n= 11.25/.125
n=90
so 90 smaller cubes will completely fill in the prism
Answer:

As you know, the length in cm for each is 4, 6, 4, 3, 5, 6, 5, 4, 3, and 6. So, you must now count how many times 4 is listed, which is 3. Now, you will look at each chart for 3 x's above the number 4. You have now eliminated the middle two. Next, count how many 3's there are, which is 2. Both have those, so eliminating other choices is a no-go. Now, look at how many 5's you have, which is 2. Look at your charts... again, no choice ca be marked-off. Finally, look at how many 6's there are, which is 3. So, look at your last options and find which one has 3 total x's above the 6. And there you go, D.

8. Find the surface area of a triangular pyramid if the area of each phase is 16 cm² and each of its lateral faces has an area of 9 cm².
Answers
Answer:
The base of a right pyramid is an equilateral triangle with area 16√3 cm². area of one of its lateral faces is 30 cm²
To find : height (in cm) i
Solution:
The base of a right pyramid is an equilateral triangle with area 16√3 cm²
Area of an equilateral triangle = (√3 / 4) Side ²
(√3 / 4) Side ² = 16√3
=> Side ² = 64
=> Side = 8 cm
Distance of center of triangle to mid point of Side for Equilateral triangle = side/ 2√3 = 8/ 2√3 = 4/√3
Let say Height = H
Slant Height = √((4/√3)² + H²)
Area of lateral surface = (1/2) * base * Slat Height
= (1/2) * 8 * Slant height = 30
=> Slant height = 15/2
15/2 = √((4/√3)² + H²)
=> 225/4 = 16/3 + H²
=> 611/12 = H²
=> H = 7.135 cm

Step-by-step explanation:
Let's solve your inequality step-by-step.
−4x−10≤2
Step 1: Add 10 to both sides.
−4x−10+10≤2+10
−4x≤12
Step 2: Divide both sides by -4.
−4x /−4 ≤ 12 /−4
= x≥−3
brainliest please?Answer:
x ≥ -3
Step-by-step explanation:
you add 10 on both sides
-4x - 10 ≤ 2
+10 +10
= -4x ≤ 12
then you divide -4 on both sides to get the x by itself
12/-4 is -3
since you divided by a negative you flip the sign

What is circumference of a circle?The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle. The circumference of a circle is the product of the constant π and the diameter of the circle.
Given that, the diameter of a bicycle wheel is 16 inches.
We know that, the radius of a circle is diameter/2
Here, radius of bicycle wheel =16/2 =8 inches
As we know, the circumference of a circle is 2πr
Now, circumference of bicycle wheel is
2×3.14×8
= 50.24 feet
The wheel to travel about 192 inches
Number of revolutions =192/50.24
= 3.82
≈ 4
The number of revolutions are 4. Therefore, option B is the correct answer.
