Find an estimate for the mean length.
cm
Answers
Answer:
10.3
Step-by-step explanation:
When calculating the mean from a grouped frequency table, first you must estimate what the value is through finding the number halfway between the value that x is greater than and less than:
The number halfway between 8 and 9 is 8.5
The number halfway between 9 and 10 is 9.5
The number halfway between 10 and 11 is 10.5
The number halfway between 11 and 12 is 11.5
Next, you have to multiply the estimated value by its frequency:
8.5 x 3 = 25.5
9.5 x 11 = 104.5
10.5 x 17 = 178.5
11.5 x 9 = 103.5
Then, add up the values you calculated and divide them by the total frequency (all the frequencies added up).
total estimated length: 25.5 + 104.5 + 178.5 + 103.5 = 412
total frequency: 3 + 11 + 17 + 9 = 40
412/40 = 10.3

Answers
Answer:
-289 degrees
Step-by-step explanation:
You are looking for what is called Coterminal Angles.
To find a coterminal angle between 0 and 360 you add or subtract 360.
In this case, we subtracted 360 from 7171 - 360 = -289 tan(-289) = 2.90If TAN 71 = 2.90 and TAN -289 = 2.90, you know -289 is your answer.Hope this helps!! Please mark Brainliest!!!

The Area of Parallelogram is 32 cm² , its Base is 8 cm. Then find its Height .
Answers
Question :-
The Area of Parallelogram is 32 cm², its Base is 8 cm . Then find its Height .Answer :-
Height of Parallelogram is 4 cm .[tex] \rule {210pt} {2pt} [/tex]
Given :-
Area of Parallelogram = 32 cm²Base of Parallelogram = 8 cmTo Find :-
Height of Parallelogram = ?Solution :-
As per the provided information in the given question, we have been given that the Area of Parallelogram is 32 cm² . Base of Parallelogram is given 8 cm . And, we have been asked to calculate the Height of Parallelogram .
For calculating the Height , we will use the Formula :-
[tex] \bigstar \: \: \boxed{ \sf{ \: Area \: _{Parallelogram} \: = \: Base \: \times \: Height \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \longmapsto \: \: \sf{ Area \: _{Parallelogram} \: = \: Base \: \times \: Height} \\ [/tex]
[tex] \longmapsto \: \: \sf{ 32 \: = \: 8 \: \times \: Height} \\ [/tex]
[tex] \longmapsto \: \: \sf{ \dfrac{32}{8} \: = \: Height } \\ [/tex]
[tex] \longmapsto \: \: \sf{ \dfrac{4}{1} \: = \: Height } \\ [/tex]
[tex] \longmapsto \: \: \textbf {\textsf {Height = 4 cm}} [/tex]
Hence :-
Height of Parallelogram = 4 cm .[tex] \underline {\rule {210pt} {4pt}} [/tex]

Area of a parallelogram is base times it's height, here so if we assume the height to be H, then:
→ H × 8 = 32
→ H = (32/8)
→ H = 4 cm
If ∠G is supplementary to ∠H and the measure of ∠G is 65° what is the measure of ∠H?
Answers
Solution:
Given:
∠G = 65°Supplementary angles are a pair of angles that sum up to 180°.
It should be noted:
If ∠G and ∠H are a pair of supplementary angles, they both sum up to 180°.Equation formed: ∠G + ∠H = 180
Substitute the values into the equation.
∠G + ∠H = 180=> 65 + ∠H = 180Subtract 65 both sides.
=> 65 - 65 + ∠H = 180 - 65=> ∠H = 180 - 65 = 115°The equation of a line is given below.

Answer:
-2 is slope and -3 in y-intercept
Step-by-step explanation:
Starting with 2x + y = -3
Subtract 2x from both sides to get y alone:
y = -2x -3
This is now in slope-intercept form, which is y=mx+b, where m=slope and b=y-intercept.
-2 is in the m spot, so it is the slope
-3 is in the b spot, so it is the y-intercept

What happens to the standard error of m as sample size increases?.
Answers
Answer:
SEM decreases by a factor of √N
Step-by-step explanation:
The standard error of the mean (SEM) is inversely proportional to the square root of the sample size. As the sample size (N) increases, the SEM is decreased by a factor of √N.
The SEM is the population standard deviation divided by √N for a normal distribution.

The shaded region area is the amount of space covered by the shaded region
The area of the shaded region is 3.75 square feet
How to determine the shaded areaThe question is incomplete, as the figure is not given.
So, I will give a general explanation
Assume that the figure has the following properties
Big rectangle of dimension, 10 ft by 5 ftSmall rectangle of dimension 3 ft by 9ftSemicircle of a diameter of 7ftStart by calculating the area of the big rectangle
Area = 10 ft * 5 ft = 50 square ft
Calculate the area of the small rectangle
Area = 3 ft * 9 ft = 27 square ft
Calculate the area of the semicircle
Area = 0.5 * 22/7 * (3.5)^2 ft = 19.25 square ft
Assume that the shaded area is outside the semicircle and the small rectangle, the shaded area would be:
Shaded area = Big rectangle - Small rectangle - Semicircle
So, we have:
Shaded area = 50 - 27 - 19.25
Shaded area = 3.75
Using the assumed values, the area of the shaded region is 3.75 square feet

Answer:
She would finish her book in 2 hours and 16 minutes
Step-by-step explanation:
6 x 34 = 204
4 x 34 = 136
136 = 2 Hours and 16 minutes
Yes, she can finish her book in 2 hours if she reads at the same rate of 6 pages every 4 minutes.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
First, we need to convert 2 hours to minutes:
So,
= 2 hours × 60 minutes/hour
= 120 minutes
Now,
6 pages/4 minutes
= 1.5 pages/minute
So in 120 minutes, she can read:
= 1.5 pages/minute × 120 minutes
= 180 pages
Thus,
Since Emma has only 200 pages left to read, she can finish her book in 2 hours if she reads at the same rate of 6 pages every 4 minutes.

Right angle triangle:A right angle triangle has one of its angles as 90 degrees. The sides can be found using Pythagoras theorem.
Therefore,
The base of the big triangle can be found as follows:
c² = a² + b²
c² = 9.2² + 5.8²
c² = 84.64 + 33.64
c = √118.28
c = 10.8756608995
c = 10.88 ft
Therefore, using similar triangle ratio,
5.8 / 10.9 = 10.9 / x + 5.8
5.8x + 33.64 = 118.81
5.8x = 118.81 - 33.64
5.8x = 85.17
x = 85.17 / 5.8
x = 14.6844827586
x = 14.68
Therefore, the height of the tree = 14.7 + 5.8 = 20.5 ft
