The total distance around Wendy's rectangular-shaped bedroom is 260 feet the width of the room is 60 feet what is the area of Wendy's bedroom use the appropriate units of measure
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

Solve the equation by completing the square
s^2+2s-6=0
s=
s=
Please answer this ASAP ! And with step by step expiation please !
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]

your equation in a y = mx + b format"
y is the outputm is the slopex is the inputb is the y interceptWHAT IS THE SLOP PLEASE HELP ME I AM TIMED
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:
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

graph y=8.5x
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

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

A design engineer wants to construct a sample mean chart for controlling the service life of a halogen headlamp his company produces. He knows from numerous previous samples that this service life is normally distributed with a mean of 500 hours and a standard deviation of 20 hours. On three recent production batches, he tested service life on random samples of four headlamps, with these results: Sample Service Life (hours) 1 495 500 505 500 2 525 515 505 515 3 470 480 460 4701. What is the sample mean service life for sample 2? A) 460 hours.B) 495 hours.C) 515 hours.D) 525 hours. 2. What is the mean of the sampling distribution of sample means for whenever service life is in control? A) 250 hours.B) 470 hours.C) 495 hours.D) 500 hours.E) 515 hours. 3. If he uses upper and lower control limits of 520 and 480 hours, on what sample(s) (if any) does service life appear to be out of control?a) sample 1.b) sample 2.c) sample 3.d) both samples 2 and 3.e) all samples are in control.
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.
