Answer:
Step-by-step explanation:
In a right triangle the tangent of an angle is the ratio of the opposite length over the adjacent*. In formulas, 
Solving for x, using a calculator for the tangent,
*I promise I didn't just spellcheck that.
The solutions to the questions are given below
a)
sample(n) word length sample mean
1 5,4,4,2 3.75
2 3,2,3,6 3.5
3 5,6,3,3 4.25
b)R =0.75
c)
- The mean of the sample means will tend to be a better estimate than a single sample mean.
- The closer the range of the sample means is to 0, the more confident they can be in their estimate.
<h3>What is the students are going to use the sample means to estimate the mean word length in the book.?</h3>
The table below shows sample means in the table.
sample(n) word length sample mean
1 5,4,4,2 3.75
2 3,2,3,6 3.5
3 5,6,3,3 4.25
b)
Generally, the equation for is mathematically given as
variation in the sample means
R =maximum -minimum
R=4.25-3.5
R =0.75
c)
In conclusion, In most cases, the mean of many samples will provide a more accurate estimate than the mean of a single sample.
They may have a higher level of confidence in their estimate if the range of the sample means is closer to 0 than it is now.

Step-by-step explanation:
Answer:
-11/20
Step-by-step explanation:
2 8 1
(0-— ÷ (0-—))+—
3 9 5
8
Simplify —
8/9
2 8 1
(0 - — ÷ (0 - —)) + —
3 9 5
Simplify —
2/3
2 -8 1
(0 - — ÷ ——) + —
3 9 5
2 -8
Divide — by ——
3 9
To divide fractions, write the divison as multiplication by the reciprocal of the divisor :
2 -8 2 9
— ÷ —— = — • ——
3 9 3 -8
(0--3/4)+1/5
Least Common Multiple:
20
Left_M = L.C.M / L_Deno = 5
Right_M = L.C.M / R_Deno = 4
3 • 5 + 4 -11
————————— = ———
20 20
-11/20
You have to have the same denominator for both fractions, so I would multiply 3/4 by 3 that would give you 9/12 and the other one is 7/12. This means that the final answer would be 9/12>7/12.
