Answer:
Scale factor=2
The perimeter of the enlarged figure is 19
The area of the enlarged figure is 4 times the area of the original figure
Step-by-step explanation:
Scaling
There are two figures, the red rectangle (original) and the blue rectangle (enlarged).
To find the scale factor we directly compare the height of both rectangles and note:
height of original rectangle=1.5
height of enlarged rectangle=3
Thus, the scale factor is 3/1.5 = 2
Scale factor=2
The original perimeter is calculated as:
P1=2*1.5+2*3.25=3+6.5=9.5
The perimeter of the enlarged figure is 2 times the original perimeter
P2=2*9.5=19
The perimeter of the enlarged figure is 19
To calculate the area of the enlarged figure, we use
A2=H2*W2
Where H2 and W2 are the height and width of the enlarged figure.
Since
H2=2*H1
W2=2*W1
A2=4*A1
The area of the enlarged figure is 4 times the area of the original figure
PLEASE HELP WILL AWARD BRAINLIEST!! A company makes chairs, loungers, and footstools. Each item uses units of wood, fabric, and stuffing. Chairs use 30 units of wood, 30 units of fabric, and 10 units of stuffing. Loungers use 25 units of wood, 15 units of fabric, and 10 units of stuffing. Footstools use 20 units of wood, 5 units of fabric, and 5 units of stuffing. There are 1,380 units of wood, 890 units of fabric, and 450 units of stuffing available to make the items. Which three equations are needed to find the largest number of x chairs, y loungers, and z footstools that can be made? Drag and drop the correct equations into the box.
Answer:
30x+25y+20z=138030x+15y+5z=89010x+10y+5z=450Step-by-step explanation:
in this problem we are expected to formulate the constraints
let chairs, loungers and footstools be x, y and z respectively
1. For wood we have
30x+25y+20z=1380
2 . For fabric we have
30x+15y+5z=890
. For stuffing we have
10x+10y+5z=450
therefore the three equation are
30x+25y+20z=1380
30x+15y+5z=890
10x+10y+5z=450

There is a 30 percent chance that A can fix her busted computer. If A cannot, then there is a 40 percent chance that her friend B can fix it.
a) Find the probability it will be fixed by either A or B.
b) If it is fixed, what is the probability it will be fixed by B.
a) The probability that the computer will be fixed by either A or B is 58%.
b) The probability that it was fixed by B is 57.14%
Given data:
a)
To find the probability that the computer will be fixed by either A or B, we can use the principle of addition for probabilities.
The probability that A can fix the computer is 30% or 0.30, and the probability that B can fix the computer if A cannot is 40% or 0.40.
Therefore, the probability that either A or B can fix the computer is the sum of these probabilities:
P(A or B) = P(A) + P(B if A cannot) = 0.30 + (0.70 * 0.40) = 0.30 + 0.28 = 0.58
Therefore, there is a 58% probability that the computer will be fixed by either A or B.
b)
Let's denote event A as A fixing the computer and event B as B fixing the computer.
P(A) = 0.30 (probability A can fix the computer)
P(B|A') = 0.40 (probability B can fix the computer given that A cannot)
To find P(B|A), the probability that B fixes the computer given that it was fixed, use Bayes' theorem:
P(B|A) = (P(A|B) * P(B)) / P(A)
Since the computer is fixed, P(A) + P(A') = 1, so P(A) = 1 - P(A') = 1 - 0.30 = 0.70
P(B|A) = (P(A|B) * P(B)) / P(A)
P(B|A) = (1 * 0.40) / 0.70
P(B|A) = 0.40 / 0.70
P(B|A) ≈ 0.5714
Hence, if the computer is fixed, there is a 57.14% probability that it was fixed by B.

g Nationwide, a certain disease occurs only a small proportion of people (.000215). A certain town has 74,000 residents. Use the Poisson approximation. c) Determine the probability that the town has 30 or fewer residents with the illness.
Answer:
The probability that the town has 30 or fewer residents with the illness = 0.00052.
Step-by-step explanation:
So, we have the following set of data or information or parameters given from the question above and they are; the number of people living in that particular society/community/town = 74,000 residents and the proportion of people that the diseases affected = .000215.
The first step to do is to determine the expected number of people with disease. Thus, the expected number of people with disease = 74,000 × .000215 = 15.91.
Hence, the probability that the town has 30 or fewer residents with the illness = 1.23 × 10^-7 × 15.91^30/ 2.65253 × 10^-32 = 0.00052.
Note the formula used in the calculating the probability that the town has 30 or fewer residents with the illness = e^-λ × λ^x/ x!

In a laboratory, 3 technicians are analyzing the active ingredient in the product vials. Amir, Betty, and Carlos analyze 0.55, 0.30, and 0.15 of the vials, respectively. Inaccurate are 0.6 percent of the analyses conducted by Amir, 0.4 percent of the analyses conducted by Betty, and 1.0 percent of the analyses conducted by Carlos in this study. What is the probability that an inaccurate analysis, detected at final verification, was conducted by Carlos
Answer:
The probability is [tex]P(C | I) = 0.025[/tex]
Step-by-step explanation:
From the question we are told that
The proportion analyzed by Amir is P(A) = 0.55
The proportion analyzed by Betty is P(B) = 0.30
The proportion analyzed by Carlos is P(C) = 0.15
The inaccuracy by Amir is p = 0.6% = 0.006
The inaccuracy by Betty is b = 0.4% = 0.004
The inaccuracy by Carlos is c = 0.1% = 0.001
Generally the probability of inaccurate analysis is mathematically represented as
[tex]P(I) = P(A) * p + P(B) * b + P(C) * c[/tex]
=> [tex]P(I) = 0.55 * 0.006 + 0.30 * 0.004 + 0.15 * 0.001 [/tex]
=> [tex]P(I) = 0.006 [/tex]
Generally the probability that an inaccurate analysis, detected at final verification, was conducted by Carlos is mathematically represented as
[tex]P(C | I ) = \frac{P(C) * c}{P(I)}[/tex]
=> [tex]P(C | I) = \frac{ 0.15 * 0.001}{ 0.006}[/tex]
=> [tex]P(C | I) = 0.025[/tex]

b. What is the rate parameter of the appropriate exponential distribution? (Round your answer to 2 decimal places.)
Rate parameter
c. Find the probability that the time to success will be more than 63 minutes. (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.)
Answer:
a
[tex]\mu = 25 [/tex]
b
[tex]\lambda =0.04 [/tex]
c
[tex]P(X > 65 ) =0.0742 [/tex]
Step-by-step explanation:
From the question we are told that
The number of success is n = 5
The time duration is N = 125 minutes
Generally the mean of the random variable is mathematically represented as
[tex]\mu = \frac{N}{n}[/tex]
=> [tex]\mu = \frac{125}{5}[/tex]
=> [tex]\mu = 25 [/tex]
Generally the rate parameter is mathematically represented as
[tex]\lambda = \frac{1}{\mu}[/tex]
=> [tex]\lambda = \frac{1}{25}[/tex]
=> [tex]\lambda =0.04 [/tex]
Generally the cumulative distribution function for exponential distribution function is
[tex]F(x) = \left \{0 \ \ \ \ \ \ x \le 0}} \atop {1 -e^{-\lambda t }\ x>0}} \right.[/tex]
Generally the probability that the time to success will be more than 63 minutes is mathematically represented as
[tex]P(X > 65 ) = 1 - P(X \le 65)[/tex]
Here
[tex]P(X \le 65) = 1 -e^{-65 * \lambda }[/tex]
=> [tex]P(X \le 65) = 1 -e^{-65 * 0.04 }[/tex]
=> [tex]P(X \le 65) = 0.92573[/tex]
So
[tex]P(X > 65 ) = 1 - 0.92573 [/tex]
[tex]P(X > 65 ) =0.0742 [/tex]

QUESTION 05 (10 points) - Sample Size Determination in Estimating Population Mean In this hypothetical scenario, you are working for a consumer protection agency. Your boss assigned you the task of conducting a survey on cheese burgers at a national restaurant chain. In your report, you would need to construct a 90% confidence interval for the mean weight of cheese burgers. Based on past surveys on cheese burgers at this restaurant chain, the standard deviation of weight is 0.21 pound. It is required that the maximum likely sampling error of mean weight be 0.05 pound. A cheese burger at the restaurant chain costs $1.29. What is the required budget in dollars (2 decimals) to have the cheese burgers in your sample, assuming no sales tax
Answer:
$ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample
Step-by-step explanation:
Here
Z∝ =1.64
Standard Deviation=S= 0.21
Sampling Error= SE= 0.05
As Sampling Error is found by
SE= z * s/√n
√n= z*s/ SE
n= (z* s/ SE)²
We use the above formula to calculate N
N= ( Z * S/SE)²
N= (1.64 * 0.21/0.05)²
N= 28.9296= 28.93
Cost of N number of burgers
= Cost *N
= $1.29 * 28.93= $ 37.32 is the required budget in dollars (2 decimals) to have the cheese burgers in your sample

What is the answer to 1/6 plus 2/3
Answer:
5/6
Step-by-step explanation:
First, you need to make sure they have a common denominator, or else addition is not possible.
Luckily, in this case, 6 and 3 are divisible.
You would multiply 2 by 2/3 to get the common denominator of 6
The new expression would be:
4/6 + 1/6
Now, you just need to add the numerators
4 + 1 = 5
The correct answer would be 5/6.

Suppose a carpenter's ruler was marked in thirty-seconds. What would be the fraction and its decimal equivalent for the mark on the ruler between 29/32 and 30/32?
Answer:
the fraction and its decimal equivalent for the mark on the ruler
= 59/64 = 0.921875
Step-by-step explanation:
Given that;
A CARPENTER 's ruler is marked in thirty seconds
mark on the ruler between 29/32 and 30/32 is the average of the values
we know that average is the summation of all terms divided by the number of appearance of terms
so
= (29/32 + 30/32) / 2
= ((29 + 30) / 32) / 2
= (59 / 32) / 2
= 59 / 64
= 0.921875
therefore the fraction and its decimal equivalent for the mark on the ruler = 59/64 = 0.921875

What are the similarities and differences between translations, reflections, and rotations? Describe a real-world transformation? Give examples of two different transformations.
Answer:
There are four main types of transformations: translation, rotation, reflection and dilation.Translation moves the object without rotating it or changing its size. Reflection flips the object about a line of reflection. Rotation rotates a figure about a fixed point. Dilation changes the size of a figure without changing its essential shape.When you reflect a point across the x-axis, the x-coordinate remains the same,but the y-coordinate is transformed into its opposite. a negative angle of rotation turns the figure in a clockwise direction.Transformation can be done in a number of ways, including reflection, rotation, and translation. ~When you reflect a point across the x-axis, the x-coordinate remains the same,but the y-coordinate is transformed into its opposite. a negative angle of rotation turns the figure in a clockwise direction.
Step-by-step explanation:
Transformation simply means changing the size and location of shapes, lines and points in the coordinate geometry
The similarities
Translations, reflections, and rotations are all rigid transformations
This means that, they do not change the side lengths and angle measure of the shape they transform.
The differences
Translation: can only change the position of shapes without rotating or flipping the shape.
Rotation: This means that a shape is to be turned around a center at a particular degree
Reflection: This simply means that, a shape is mirrored over a line
