Ahamd wants to cover a box that is 6 cm long 4 cm high and 4 cm wide with material on all the sides how much material does he need
Answers
Answer:
56cm²
Explanation:
the amount of material he needs would be the total surface area of the box. surface area can be calculated by finding the sum of surface area of all the sides of the box. since the opposite sides are equal, we can find the surface area of 3 different sides and then multiply it by 2.
(4 + 4) + (4 + 6) + (6 + 4) × 2
= 8 + 10 + 10 × 2
= 28 × 2
= 56cm²

Three different methods for assembling a product were proposed by an industrial engineer. To investigate the number of units assembled correctly with each method, 30 employees were randomly selected and randomly assigned to the three proposed methods in such a way that each method was used by 10 workers. The number of units assembled correctly was recorded, and the analysis of variance procedure was applied to the resulting data set. The following results were obtained: SST = 10,800; SSTR = 4560.
Required:
a. Set up the ANOVA table for this problem.
b. Use α= .05 to test for any significant difference in the means for the three assembly methods.
Answers
Answer:
H0 is rejected.There difference in the means for the three assembly methods.
Step-by-step explanation:
Calculating gives the following results.
ANOVA Table
Source DF Sum Mean F Statistic
of Square Square
Treatments 2 4560 2280 9.865
(between groups)
Error 27 6240 231.111
Total 29 10,800
Error SS= SST -SSTR = -10,800-4560=6240
d.f for SSTr = r-1= 3-1
D.f for SST= n-r= 30-3= 27
Total D.f= d.f for SSTr+D.f for SST= 27+29
MSTR= SSTR/d.f= 4560/2= 2280
MSError= Error SS/ d.f= 6240/27=231.111
F test= MSTR/ MsError= 2280/231.11= 9.865
The P- value < 0.01 which is less than 0.05 therefore H0 is rejected.
There is sufficient evidence to reject H0.

John needs to divide the sample in half once the number of bacteria has reached 1000. How many hours after the initial time must be divide the sample?
Answers
Answer:
Option A
Step-by-step explanation:
The complete question is attached here
The rate of increase of bacterial population be K
As we know
[tex]Y = Y_0 * e^{kT}[/tex]
where Y is the final population. In this case it is 1000
K is the rate of increase of population i.e 3 times per hour
T is the time in hours
Y0 is the initial population = 5
Substituting the given values, we get -
[tex]1000 = 5 *e^{3*T}\\200 = e^{3*T}[/tex]
Taking log on both sides, we get -
ln [tex]200[/tex] = ln [tex]e^{3T}[/tex]
[tex]2.718 * 2.301 = 3T[/tex]
T = 2.084 hours
hence, option A is correct
The number of hours required after the initial time must be divide the sample by John is 2.084 hours.
What is an exponential function?Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.
The exponential function with dependent variable y and independent variable x can be written as,
[tex]y=ba^x+c[/tex]
Here, a, b, and c are the real number
John needs to divide the sample in half once the number of bacteria has reached 1000.
The table of this bacterial growth is,
Time(hours) Number of bacteria
0 5
1 15
2 45
The rate of increasing the bacteria each hour is,
[tex]x=\dfrac{15}{5}=3\\x=\dfrac{45}{15}=3[/tex]
Thus, the exponential rate is 3.
Now the number of reached is 1000, and the initial population was 5. Therefore, for the time t, the exponential function can be given as,
[tex]1000=5e^{3t}\\\dfrac{1000}{5}=e^{3y}\\200=e^{3y}[/tex]
Taking log both the sides as,
[tex]\ln (200)=\ln e^{3t}\\2.301=0.434({3t})\\t=2.084[/tex]
Hence, the number of hours required after the initial time must be divide the sample by John is 2.084 hours.

A random sample of 41 cars in the drive-thru of a popular fast food restaurant revealed an average bill of $19.55 per car. The population standard deviation is $6.33. Estimate the mean bill for all cars from the drive-thru with 97% confidence.
Answers
Answer:
[tex]19.55\pm2.145[/tex]
Step-by-step explanation:
We use the equation [tex]\bar x\pm z^*\sigma/\sqrt n[/tex], where [tex]\bar x=19.55[/tex], [tex]\sigma=6.33[/tex], [tex]n=41[/tex], and [tex]z^*=2.17[/tex]. We obtain [tex]z^*[/tex] from the z-score of a 0.97 confidence level.
The 97% confidence interval estimate for the mean bill for all cars from the drive-thru is approximately $17.23 to $21.87.
To estimate the mean bill for all cars from the drive-thru with 97% confidence, we can use a confidence interval.
Sample size (n) = 41
Sample mean (x(bar)) = $19.55
Population standard deviation (σ) = $6.33
To calculate the confidence interval, we'll use the formula:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
First, we need to calculate the standard error, which is the standard deviation of the sample mean.
Standard Error (SE) = Population Standard Deviation / √(Sample Size)
SE = $6.33 / √(41)
Next, we determine the critical value based on the desired confidence level. Since we want a 97% confidence interval, we need to find the critical value corresponding to a 97% confidence level.
The critical value can be obtained from a standard normal distribution table or by using a calculator. For a 97% confidence level, the critical value is approximately 2.17.
Now, we can calculate the confidence interval:
Confidence Interval = $19.55 ± (2.17 * SE)
Substituting the values:
Confidence Interval = $19.55 ± (2.17 * ($6.33 / √41))
Calculating this, we find:
Confidence Interval ≈ $19.55 ± $2.32
Therefore, the 97% confidence interval estimate for the mean bill for all cars from the drive-thru is approximately $17.23 to $21.87.

If a cube has a volume of 1/8 cubic units, what is the area of one or its faces?
Answers
Answer:
The area of one of the faces of the cube is equal to 1/4 cubic units.
Step-by-step explanation:
Given that a cube has a volume of 1/8 cubic units, to determine what is the area of one of its faces, the following calculations must be performed, knowing that the volume of a cube is equal to the value of one of its sides cubed , and the area of one of its faces is equal to the multiplication between its base and its height:
1/8 = 0.125
3√0.125 = 0.5
0.5 x 0.5 = 0.25
0.25 = 1/4
Therefore, the area of one of the faces of the cube is equal to 1/4 cubic units.
In a particular year, a total of 50,127 students studied in two of the most popular host countries when traveling abroad. If 8383 more students studied in the most
popular host country than in the second most popular host country, find how many students studied abroad in each country.
There were students who studied abroad in the most popular host country.
Answers
Answer:
In the most popular abroad country: 29,255 students
In the second-most one: 20,872 students
Step-by-step explanation:
Let's write the situation in an equation to help us solve this. X represents the amount of students in the second most popular country. So we know that in total, there's 50,127 students so let's make an equation that equals this. ???????=50,127. As we know, the most popular country has 8383 more students than the second one so we can write it as x+8383 and for the second most popular country, we can write it as x. We know that both of the countries students combined equal 50,127 students so we have our equation. (x)+(x+8383)=50,127 students. After solving the equation, you get x=20, 872. As we know x=the amount of students in the second most popular country which means there's 20,872 students in the second one. Additionally, for the first most popular one, the equation for the amount of students in it is x+8383 so..... 20,872+8383=Total number of students in the most popular one which is 29,255 students.

tickets and every hour about 75
tickets are sold. How long will it
take for there to be only 150 tickets
left?
Answers
Answer:
It will take 10 hours
Step-by-step explanation:
first you subtract 150 from 900 (900-150) to get 750. next you divide 750 by 75 since that is the rate the tickets are being sold (750÷75) which would equal to 10.
