Answer: (0.79, 3.05 )

Step-by-step explanation:

Confidence interval for the population mean:

[tex]\overline{x}\pm z^c\dfrac{\sigma}{\sqrt{n}}[/tex]

, where [tex]\overline{x}[/tex] = Sample mean

[tex]\sigma[/tex] = population standard deviation

n= sample size.

[tex]z^c[/tex] = Critical z value for confidence interval c.

As per given:

n= 10

[tex]\overline{x}=1.92[/tex]

[tex]\sigma=1.83[/tex]

Critical z-value for 95% confidence = 1.96

A 95% confidence interval for the mean opinion in the population of all licensed drivers:-

[tex]1.92\pm (1.96)\dfrac{1.83}{\sqrt{10}}\\\\=1.92\pm1.134\\\\= (1.92-1.134,\ 1.92+1.134)\\\\\approx(0.79,\ 3.05 )[/tex]

Hence, a 95% confidence interval for the mean opinion in the population of all licensed drivers = (0.79, 3.05)

Answer: [tex]1\dfrac{3}{4}\text{ feet}[/tex]

Step-by-step explanation:

Given: Length of sandwich = [tex]10\dfrac12\text{ feet}=\dfrac{21}{2}\text{ feet}[/tex]

Total people = 14

If everyone gets a same sized piece , then length of each piece should be

[tex]\dfrac{\text{ Length of sandwich}}{\text{Total people}}[/tex]

[tex]=\dfrac{\dfrac{21}{2}}{14}\text{ feet}\\\\=\dfrac{21}{2\times14}\text{ feet}\\\\=\dfrac{7}{2\times2}\text{ feet}\\\\=\dfrac{7}{4}\text{ feet}\\\\=1\dfrac{3}{4}\text{ feet}[/tex]

Hence, length of each piece = [tex]1\dfrac{3}{4}\text{ feet}[/tex]

The error was done in Step E, because student did not multiply [tex]2\cdot x -8[/tex] by the negative sign in numerator. Step E must be [tex]\frac{2\cdot x -5}{(x+4)\cdot (x-4)}[/tex].

The error was done in Step C, because the student omitted the [tex]2\cdot a \cdot b[/tex] of the algebraic identity [tex](a+b)^{2} = a^{2}+2\cdot a\cdot b +b^{2}[/tex]. Step C must be [tex]5\cdot x = x^{2}+4\cdot x + 4[/tex]

Step-by-step explanation:

First image attached

The error was done in Step E, because student did not multiply [tex]2\cdot x -8[/tex] by the negative sign in numerator. The real numerator in Step E should be:

[tex]3-(2\cdot x -8)= 3-2\cdot x+8 = 11-2\cdot x[/tex]

Hence, Step E must be [tex]\frac{2\cdot x -5}{(x+4)\cdot (x-4)}[/tex].

The error was done in Step C, because the student omitted the [tex]2\cdot a \cdot b[/tex] of the algebraic identity [tex](a+b)^{2} = a^{2}+2\cdot a\cdot b +b^{2}[/tex]. Step C must be [tex]5\cdot x = x^{2}+4\cdot x + 4[/tex]

And further steps are described below:

Step D

[tex]x^{2}-x+4 = 0[/tex]

Which according to the Quadratic Formula, represents a polynomial with complex roots. That is: ([tex]a = 1[/tex], [tex]b = -1[/tex], [tex]c = 4[/tex])

[tex]D = b^{2}-4\cdot a\cdot c[/tex]

[tex]D = (-1)-4\cdot (1)\cdot (4)[/tex]

[tex]D = -17[/tex] (Conjugated complex roots)

Step E

[tex](x-0.5-i\,1.936)\cdot (x-0.5+i\,1.936) = 0[/tex]

Step F

[tex]x = 0.5+i\,1.936\,\lor\,x = 0.5-i\,1.936[/tex]

Answer:

181 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

To find how many hours they work per month multiply the amount of hours they work each day by the amount of days they work in a month:

[tex]22 *8\frac{1}{4} = 181\frac{1}{2}[/tex]

They work [tex]181\frac{1}{2}[/tex] hours per month.

Hope this helps :)

Let H = the amount of hours the employee works per month.

H = 22 • 8_1/4

H = 22 • 33/4

H = 11 • 33/2

H = 363 ÷ 2

H = 181.5 hours per month

Answer 8400 divided by 7 is 1200

Answer:

x = 88

Step-by-step explanation:

All angles in a triangle equal 180 degrees. So our equation will be:

x + 48 + (x - 44) = 180

x + 48 + x - 44 = 180

2x + 48 - 44 = 180

2x + 4 = 180

2x = 176

x = 88

Answer:

18h - 3hk

Step-by-step explanation:

3h(6 - k)

= 3h(6) + 3h(-k)

= 18h + -3hk

= 18h - 3hk

The simplified for of the expression 2.3h(6 - k) can be written as 13.8h - 2.3hk

Given the expression :

2.3h(6 - k)

Open the bracket ; multiply values in the bracket by 2.3h

13.8h - 2.3hk

Since there is no other way to reduce the expression further, then the simplified form of the expression would be expressed as 13.8h - 2.3hk

Answer:

2.21

Step-by-step explanation:

Total meters of wood = 7.58

first time shopping: 2.25

second time shopping: 3.12

total = 2.25 + 3.12

total = 5.37

How many more meters of wood does Jack need to buy for his school project?

Meters needed = 7.58 - 5.37

Meters needed = 2.21

Answer:

4/3

Step-by-step explanation:

To find the slope you use the equation y2 - y1 / x2 - x1. This means you take the y variable from your 1st point and subtract it from the y variable from the 2 one. ex: 1 - (-3) = 4 And then put it over the x variable from the first one subtracted from the x variable of the second one ex: 5 - 2 = 3 -> 4/3. If possible, simplify, but if it's like this one you don't have to.

Well, I dont know how many people there are, but she would have 40 slices of pie if she bought 5 pies with 8 slices each.

Step-by-step explanation:

5 x 8 = 40

5+5+5+5+5+5+5+5=40

The range of the domain 0. 1, 2, 3, 4, and 5 would be 5.

When the sample maximum and minimum are subtracted, the range of a collection of data is the difference between the greatest and lowest values. It uses the same units as the data to express itself.

The lowest and largest numbers in the set of data are subtracted to determine the range. Here, the numbers are 0 and 5. Thus, after subtraction, you get 5.

The range will be calculated as:-

Range = 5 - 0

Range = 5

Hence, the range will be 5.
