Answer:

48.668 ≤ μ ≤ 63.332

Step-by-step explanation:

Given the data:

Sample (X) : 71, 45, 54, 75, 50, 49, 63, 55, 48, 50

Number of samples (n) = 10

α = 95% = 0.05

Determine the range within which the true mean of the fluid samples from the day shift will be with a 95% confidence

True mean = μ

Confidence interval :

m ± t(α/2 ; df) * s/√n

m - t(α/2 ; df) * s/√n ≤ μ ≤ m + t(α/2 ; df) * s/√n

m = sample mean ; s = sample standard deviation ; df = degree of freedom =(n - 1) = (10 - 1) = 9

Calculating the sample mean and standard deviation using calculator to save computation time :

71, 45, 54, 75, 50, 49, 63, 55, 48, 50

m = 56 ; s = 10.25

m - t(0.05/2 ; 9) * s/√n ≤ μ ≤ m + t(0.05/2 ; df) * s/√n

From t table : t(0.05/2 ; 9) = t(0.025, 9) = 2.262

56-2.262 * (10.25/√10) ≤ μ ≤ 56+2.262 * (10.25/√10)

48.668 ≤ μ ≤ 63.332

Answer:

The solution is [tex]\displaystyle x=1\pm \sqrt{47}[/tex]. Fourth option

Explanation:

Solve for x:

[tex]2x^2+3x-7=x^2+5x+39[/tex]

Move all the terms from the right to the left side of the equation, a zero in the right side:

[tex]2x^2+3x-7-x^2-5x-39=0[/tex]

Join all like terms:

[tex]x^2-2x-46=0[/tex]

The general form of the quadratic equation is:

[tex]ax^2+bx+c=0[/tex]

Solve the quadratic equation by using the formula:

[tex]\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

In our equation: a=1, b=-2, c=-46

Substituting into the formula:

[tex]\displaystyle x=\frac{-(-2)\pm \sqrt{(-2)^2-4(1)(-46)}}{2(1)}[/tex]

[tex]\displaystyle x=\frac{2\pm \sqrt{4+184}}{2}[/tex]

[tex]\displaystyle x=\frac{2\pm \sqrt{188}}{2}[/tex]

Since 188=4*47

[tex]\displaystyle x=\frac{2\pm \sqrt{4*47}}{2}[/tex]

Take the square root of 4:

[tex]\displaystyle x=\frac{2\pm 2\sqrt{47}}{2}[/tex]

Divide by 2:

[tex]\displaystyle x=1\pm \sqrt{47}[/tex]

First option: Incorrect. The answer does not match

Second option: Incorrect. The answer does not match

Third option: Incorrect. The answer does not match

Fourth option: Correct. The answer matches exactly this option

BECAUSE U ADD 20+15+15!!!  

:)

Step-by-step explanation:

A.let n be 1

a1=2(1)+3

T1=5

let n be 2

2(2)+3

T2=7

T3=2(3)+3

=9

T4=2(4)+3

=11

A. For the sequence given by the nth term formula an = 2n + 3, the first four terms are:

a1 = 2(1) + 3 = 5

a2 = 2(2) + 3 = 7

a3 = 2(3) + 3 = 9

a4 = 2(4) + 3 = 11

For the sequence given by the nth term formula an = n² - 1, the first four terms are:

a1 = 1² - 1 = 0

a2 = 2² - 1 = 3

a3 = 3² - 1 = 8

a4 = 4² - 1 = 15

B. The missing terms for the sequence 57, 47, 37, 27,  17 are:

57, 47, 37, 27, 17

The missing terms for the sequence -12,-6, , 0, 12, 24, 36 are:

-12, -6, 0, 12, 24, 36

The missing terms for the sequence -4, 8,20, , 16, -20 are:

-4, 8, 20, 16, -20

C. The general rule or nth term for the sequence 7, 12, 17, 22,... is:

an = 5n + 2

The general rule or nth term for the sequence 2, 6, 12, 20,... is:

an = n² + 1

D. The sequence 4, 8, 12, 16,.. is an arithmetic sequence with a common difference of 4.

The sequence 13, 10, 7, 4,... is an arithmetic sequence with a common difference of -3.

The sequence -10, -8, -6, -4,.. is an arithmetic sequence with a common difference of 2.

The sequence 1, 6, 8, 11, 12,.. is not an arithmetic sequence as there is no common difference between consecutive terms.

The sequence 5, 6, 12, 13,... is not an arithmetic sequence as there is no common difference between consecutive terms.

Step-by-step explanation:

-1 (-4) = -5

It will cost $412.50 for equipment for all stations.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Dan orders supplies for the science lab. Each of the 30 stations in the chemistry lab needs 5 feet of rubber tubing. If rubber tubing sells for $8.25 per yard.

The cost will be calculated as below,

3 feet = 1 yard

5 x 30 = 150 feet

8.25 per yard = cost

150/ 3 = 50 yards (total tubing needed)

50 x 8.25 = $ 412.50

Answer:

  KE = 100 J

Step-by-step explanation:

The question is asking you to use the formula with the values ...

  m = 8 kg . . . . . this 'm' stands for mass

  v = 5 m/s . . . .  this 'm' stands for meters

Putting these values into the formula, we have ...

  KE = 1/2(8 kg)(5 m/s)² = 100 kg·m²/s²

The units are equivalent to the derived SI unit "joules", abbreviated J.

The kinetic energy of the 8 kg mass is 100 J.

Answer:

x > -2

Step-by-step explanation:

An open circle (unshaded) which starts at -2 and drawn to the right means that the possible values of x do not include -2. Possible values of x are greater than -2, upwards.

Therefore, the inequality to use in representing the information displayed by the graph is x > -2.

This means possible values of x are greater than -2.

Answer:

  86 m^2

Step-by-step explanation:

The figure is equivalent to a rectangle that is 8 m by 12 m, with a triangle cut off. The width of the triangle is (12 m-8 m) = 4 m. The height of the triangle is (8 m-3 m) = 5 m.

Then the figure's area is ...

  A = LW - (1/2)bh

  A = (12 m)(8 m) -(1/2)(4 m)(5 m) = 96 m^2 -10 m^2

  A = 86 m^2

The area of the figure is 86 square meters.

Answer:

m = 0

Step-by-step explanation:

To find the slope, use the formula:

m = y2 - y1 / x2 - x1

Then substitute the numbers:

m = 5 - 5 / 6 - 3

m = 0 / 3

m = 0

Therefore, the slope of the line is 0.
