Aleonysh [2.5K]

The confidence interval at 95% level is

7106.87 <  μ< 14255.27

<h3>What is meant be mean and standard deviation?</h3>

The ratio of sum of observations to the total number of observation is known as mean. It is one of the central tendency in the statistics. It gives an idea about the central value present in the data. The most sensitive measure of central tendency is mean. It is very easy to calculate. Mean playa a crucial role in daily life. The two types of means are Arithmetic mean and Geometric mean.

Standard deviation is a measure in the statistics. The amount of variation of a set of values is known as standard deviation. Standard deviation is denoted by σ.

As per given data

90% confident level for amount of electricity used in community of Austin is

X-tx/2(n-1)s/√n < μ < X+ tx/2(n-1)s/√n

Here , n=12 ,  X=10681.07 , s=6893.87

Margin of error = tx/2(n-1)s/√n

=(1.796×6893.87)/√12

=3574.1996

=3574.19(approximately)

Therefore, 90% CI is,

10681.07-3574.19 ≤ μ<10681.07+3574.19

7106.87 <  μ< 14255.27

What is the value of x to the nearest<br> tenth?
Colt1911 [192]

Answer:

C. 17.6

General Formulas and Concepts:

<u>Math</u>

  • Rounding

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right  

Equality Properties

  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Trigonometry</u>

  • [Right Triangles Only] SOHCAHTOA
  • [Right Triangles Only] tanθ = opposite over adjacent

Step-by-step explanation:

<u>Step 1: Identify Variables</u>

Angle θ = 40°

Opposite Leg = <em>x</em>

Adjacent Leg = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Substitute in variables [tangent]:                                                                   \displaystyle tan(40^\circ) = \frac{x}{21}
  2. [Multiplication Property of Equality] Isolate <em>x</em>:                                                \displaystyle 21tan(40^\circ) = x
  3. Rewrite:                                                                                                           \displaystyle x = 21tan(40^\circ)
  4. Evaluate:                                                                                                          \displaystyle x = 17.6211
  5. Round:                                                                                                            \displaystyle x \approx 17.6

1. Which statement is false?
kompoz [17]

Answer:

Option C is false.

Step-by-step explanation:

A. We are given; 0.7 < 4/5

Now, 4/5 in decimal form is written as 0.8.

Thus,0.7 is less than 0.8. So statement is true.

B) We are given: 2/3 > 0.34

Now, 2/3 in decimal form is written as 0.67.

Thus,0.67 is greater than 0.34, so statement is true.

C) We are given: 2.26 > 214

214 is obviously greater than 2.26. Thus statement is false.

D) We are given: 35/6 > 37/8

Now, 35/6 in decimal form is written as 5.83.

Likewise, 37/8 is written in decimal form as 4.63

Thus,5.83 is greater than 4.63, so statement is true.

Finally, the only false one is Option C
