Answer:
Final cost = £779
Step-by-step explanation:
It is given that:
Cost of summer holiday = £650
Amount increased by 11%
Increased cost = 11% of 650
Increased cost =
Increased cost = 0.11 * 650 = £71.50
Amount after increment = 650 + 71.50 = £721.50
Further increase = 8%
Amount = 0.08 * 721.50 = £57.72
Final cost = 721.50 + 57.72 = £779.22
Thus,
Final cost = £779

b)
Step-by-step explanation:
Assuming this question: Temperature transducers of a certain type are shipped in batches of 50. A sample of 60 batches was selected, and the number of transducers in each batch not conforming to design specifications was determined, resulting in the following data:
2,1,2,4,0,1,3,2,0,5,3,3,1,3,2,4,7,0,2,3,
0,4,2,1,3,1,1,3,4,2,3,2,2,8,4,5,1,3,1,
5,0,2,3,2,1,0,6,4,2,1,6,0,3,3,3,6,2,3
(a) Determine frequencies and relative frequencies for the observed values of x = number of nonconforming transducers in a batch. (Round your relative frequencies to three decimal places.)
For this case first we order the dataset on increasing way and we got:
0 0 0 0 0 0 0
1 1 1 1 1 1 1 1 1 1
2 2 2 2 2 2 2 2 2 2 2 2 2
3 3 3 3 3 3 3 3 3 3 3 3 3 3
4 4 4 4 4 4
5 5 5
6 6 6
7
8
And we can construct the following table:
X Freq. Rel Freq.

0 7 (7/58) = 0.121
1 10 (10/58)=0.172
2 13 (13/58) =0.224
3 14 (14/58)=0.241
4 6 (6/58)=0.103
5 3 (3/58)=0.052
6 3 (3/58)=0.052
7 1 (1/58) =0.017
8 1 (1/58)=0.017

(b) What proportion of batches in the sample have at most four nonconforming transducers? (Round your answer to three decimal places.)
For this case this proportion would be:
Hey there! :D
1. c - 7 = 32
To solve this problem, add the difference and the subtrahend of the given equation.
Checking:
To check, simply substitute the conclusion on the unknown quantity.
39 (c) - 7 = 32
Thus, the equation was correct which gives us the answer that:
2. r + 4 = 39
To solve this problem, subtract the sum and the addend of the given equation.
Checking:
To check, simply substitute the conclusion on the unknown quantity.
35 (r) + 4 = 39
Thus, the equation was correct which gives us the answer that:
