The height of six trees in a parkway are 5 meters, 8 meters, 12 meters, 6 meters, 11 meters, and 5 meters. Find the mean height of the six trees. A. 7 meters B .7.83 meters C.8.21 meters D.12 meters
Answers
Answer:
The answer is B, 7.83 meters.
Step-by-step explanation:
The mean of the six trees refers to the average height of all six trees. To find the mean value of any set of values, simply follow this formula:
Mean = [tex]\frac{Sum of all values}{Number of values you used}[/tex]
So for this particular question, my working was:
Mean = (5m + 8m + 12m + 6m + 11m + 5m)/6 = 7.833333333333m (Round off to 3 significant figures to get 7.83m)

An ANOVA procedure is applied to data obtained from 6 samples where each sample contains 10 observations. The degrees of freedom in the denominator for the critical value of F test statistic is Group of answer choices
Answers
Answer:
The degree of freedom in the denominator = 114
Step-by-step explanation:
For Analysis of Variance procedure :
The number of groups, k is the number of distinct groups = 6
The total number of samples, N = number of groups multiplied by the number of samples per group ; N = 20 * 6 = 120
Degree of freedom (df) :
dfwithin = df of numerator = k - 1 = 5
df between = df of denominator = N - k
df denominator = 120 - 6 = 114

Using the diagram, calculate the values of the unknown variables: a, b, and c.
Answers
Answer:
a = 82
b = 130
c = 118
Step-by-step explanation:
A quadrilateral is inscribed in a circle. So, it is a cyclic quadrilateral.
Opposite angles of a cyclic quadrilateral are supplementary.
Therefore,
a° + 98° = 180°
a° = 180° - 98°
a° = 82°
a = 82
By inscribed angle theorem:
a° = 1/2(b° + 34°)
82° * 2 = b° + 34°
164° - 34° = b°
b° = 130°
b = 130
Again by inscribed angle theorem:
76° = 1/2(c° + 34°)
76° *2 = c° + 34°
152° - 34° = c°
c° = 118°
c = 118

Charlotte thinks of a number.
She increases it by one fifth, and then reduces that answer by one half.
She finishes with 39.
What number did she start with?
Answers
Answer:
Charlotte started with 65.
Step-by-step explanation:
In order to find what number Charlotte started with, we need to go backward. So first, multiply by 2, then multiply by 5/6. 39 multiplied by 2 is 78, which is 6/5 of the number Charlotte started with. So what we need to do is multiply 78 by 5/6. That equals 390/6, which is 65. The problem has been solved. Charlotte started with 65.

Find the area of the smaller sector round to the nearest tenth. Need help fast!!
Answers
The area of the sector is 76. 95 m
How to determine the area of a sector
Using the formula;
Area of sector of a circle = /360° (r2)
where r is the radius of the circle
is the angle of the sector
From the diagram,
= 77°
r = 10. 7m
= 3. 142
Substitute into the formula
Area of the sector = 77/ 360° * (3. 142* 10. 7 * 10. 7)
Area of the sector = 0. 2139 * 359. 72
Area of the sector = 76. 95 m

Step-by-step explanation:
Area of the pyramid = area of the square + 4(area of the triangle)
Area of square = s²
s = 9.2 in.
Area of the square = 9.2² = 84.64 cm²
✔️Area of the 4 triangles = 4(½*bh)
b = 9.2 in.
h = 7.4 in.
Area = 4(½*9.2*7.4) = 136.16 in²
✅Surface area = 84.64 + 136.16 = 220.8 in.²
