Answer:

C) 515 hours.

D) 500 hours

c) sample 3

Step-by-step explanation:

1. Sample 2 mean = x2`= ∑x2/n2= 2060/4= 515 hours

Sample Service Life (hours)

1                2              3

495      525            470

500         515           480

505        505            460

500         515             470        

∑2000     2060         1880

x1`= ∑x1/n1= 2000/4= 500 hours

x2`= ∑x2/n2= 2060/4= 515 hours

x3`= ∑x3/n3= 1880/4=  470 hours

2. The mean of the sampling distribution of sample means for whenever service life is in control is 500 hours . It is the given mean in the question and the limits are determined by using  μ ± σ , μ±2 σ  or μ ± 3 σ.

In this question the limits are determined by using  μ ± σ .

3. Upper control limit = UCL = 520 hours

Lower Control Limit= LCL = 480 Hours

Sample 1 mean = x1`= ∑x1/n1= 2000/4= 500 hours

Sample 2 mean = x2`= ∑x2/n2= 2060/4= 515 hours

Sample 3 mean = x3`= ∑x3/n3= 1880/4=  470 hours

This means that the sample mean must lie within the range 480-520 hours but sample 3 has a mean of 470 which is out of the given limit.

We see that the sample 3 mean is lower than the LCL. The other  two means are within the given UCL and LCL.

This can be shown by the diagram.

Answer:

3x-4y=-9

Step-by-step explanation:

Answer:

[tex]y=\frac{3}{4}x+\frac{9}{4}[/tex]

Step-by-step explanation:

[tex]y-6=\frac{3}{4}(x - 5)[/tex] to y = mx  + b

[tex]y-6=\frac{3}{4}(x-5)\\\\Distribute;\\\\y-6=\frac{3}{4}x-\frac{15}{4} \\[/tex]

Add 6 to both sides;

[tex]-\frac{15}{4}+6 =-\frac{15}{4}+\frac{6}{1} \\\\\frac{-15+24}{4} =\frac{9}{4}[/tex]

Answer:

D. Si because the other options aren't correct.

The square root of 16 is 4 so it would be 4i but the other options aren't 4i so it would be si :D Hope this helps

Step-by-step explanation:

Answer:

the answer is 2 because between the points it goes up to and over 1 which make the slope 2/1 or 2.

Step-by-step explanation:

The slope is 2. You can figure it out by counting how many units you go up/down and dividing it by how many units you go left/right. This is called “rise over run”

Answer:

Step-by-step explanation:

Step one:

given

let the total amount of her test be x

we are told that she complete 1/8x  test in 2/5 of  an hour

hence she completed 1/8x in 0.4 hours

let us find the rate at which she completes are test

rate= 1/8x/0.4

convert the numerator to decimal number for easy computation

rate= 0.125x/0.4

rate=0.3125x per hour

Step two:

Hence 1 hour she can finish 0.3125x *1

=0.3125x

She can finish 31.25 % of her test in 1 hour

or 1/16 of her test

Answer:

Step-by-step explanation:

Find the graph below;

The standard equation of a line is expressed as y = mx + b where;

m is the slope of the line

b is the y-intercept

Given the expression y = 8.5x

On comparing with the expression

mx = 8.5 x

m = 8.5

b = 0

This means that the line must pass through the origin as shown and the slope of the line is 8.5

Answer:

s = - 1 ± [tex]\sqrt{7}[/tex]

Step-by-step explanation:

Given

s² + 2s - 6 = 0 ( add 6 to both sides )

s² + 2s = 6

To complete the square

add ( half the coefficient of the s- term )² to both sides

s² + 2(1)s + 1 = 6 + 1

(s + 1)² = 7 ( take the square root of both sides )

s + 1 = ± [tex]\sqrt{7}[/tex] ( subtract 1 from both sides )

s = - 1 ± [tex]\sqrt{7}[/tex]

Thus

s = - 1 - [tex]\sqrt{7}[/tex] , s = - 1 + [tex]\sqrt{7}[/tex]

Answer: x=-4

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

Step 1: Flip the equation.

2x + 16 = 8

Step 2: Subtract 16 from both sides.

2x + 16 − 16 = 8 − 16

2x = −8

Step 3: Divide both sides by 2.

x = −4

Answer:

4200 square feet

Step-by-step explanation:

First, find the length of the room

Since the width is 60 feet, both widths add to 120.

Subtract 120 from 260, then divide that by 2:

(260 - 120) / 2

140 / 2

= 70

So, the length is 70 feet.

Use the area formula:

A = lw

A = (70)(60)

A = 4200

So, the area of Wendy's bedroom is 4200 square feet

Step-by-step explanation:

27 * 3 = 81

81 * 3 = 243

Each term is 3x the number before it. Therefore:

3 * 3 = 9

The missing number is 9.

Answer:

The missing number would be 9.

Step-by-step explanation:

I found out that the rule is 3 multiplied.

3 times 3 = 9

9 times 3 = 27

27 times 3 = 81

81 times 3 = 243

Answer:

C and D are correct in my calculations, I'm confused.. ;w;

Step-by-step explanation:

4x + 9 + 79 - x + y = 180

4x - x + y + 79 + 9 = 180

3x + y + 88 = 180

3x + y = 180 - 88

3x + y = 92

y = 92 - 3x

A.) x = 64, y = 50

y = 92 - 3x

(50) = 92 - 3(64)

50 = 92 - 192

50 ≠ - 100

B.) x = 14, y = 152

y = 92 - 3x

(152) = 92 - 3(14)

152 = 92 - 42

152 ≠ 50

C.) x = 23.3, y = 22.1

y = 92 - 3x

(22.1) = 92 - 3(23.3)

22.1 = 92 - 69.9

22.1 = 22.1

D.) x = 14, y = 50

y = 92 - 3x

(50) = 92 - 3(14)

50 = 92 - 42

50 = 50
