Answer:
2.86 hours = £26.57
Step-by-step explanation:
5 builders = 3.5 hours
<u>Express it in ratio form:</u>
5 : 3.5 (B1:H1)
<u><em>However, on Tuesday 2 builders(B2) are available. We can set up a proportion to find the number of hours.</em></u>
<u><em>Since This is an inverse proportion, it will be written like:</em></u>
=> B1:H1 = H2:B2
Where H2 = x(no. of hours)
=> 5 : 3.5 = x : 2
<u><em>Product of means = Product of Extremes</em></u>
=> 5*2 = 3.5x
=> 10 = 3.5 x
Dividing both sides by 3.5
=> x = 2.86 hours
<u><em>Now, On Tuesday:</em></u>
1 hour = £9.3
<u><em>For 2.86 hours,</em></u>
2.86 hours = £9.3 × 2.86
2.86 hours = £26.57

Answer:
80 chocolates type 'a' and 240 chocolates type 'b'
Step-by-step explanation:
The company selects 25 random packages of each type from which one of type a has an incorrect weight and three of type b have an incorrect weight.
We can say that 
= 4% of the chocolates type 'a' have an incorrect weight while 
= 12% of chocolates type 'b' have an incorrect weight.
Now, if the company selects 2000 random chocolates of each type we ca predict that the amount of chocolates that have an incorrect wright will be:
Type 'a': 2000x0.04 = 80
Type 'b': 2000x0.12 = 240
So the company is expected to find 80 chocolates type 'a' and 240 chocolates type 'b' that have incorrect weight.
Answer:
- Mean will Increase .
- Median remains unchanged.
- Standard deviation will increase.
Step-by-step explanation:
We are given that there are 14 employees in a particular division of a company and their salaries have a mean of $70,000, a median of $55,000, and a standard deviation of $20,000.
And also the largest number on the list is $100,000 but By accident, this number is changed to $1,000,000.
Now we have to analyse the Effect of this change in data values on mean, median, and standard deviation.
- Mean will get affected because $1,000,000 is a very huge value as compared to $100,000 and is considered to be an outlier and we know that mean is affected by outliers as mean will change to $134285.7143 after replacing $100,000 with $1,000,000 .
- Median will not get affected as median the middle most value in the data set and since $1,000,000 is considered to be an outlier so median remain unchanged at $55,000 .
- Standard Deviation will also get affected as due to outlier value in the data set the numerator value will increase very much and due to which standard deviation will also increase.
