The data set shows the weights of pears, in grams, in a crate of fruit. 143, 146, 158, 159, 162, 166, 169, 170, 170, 193, 197 Wh

197 and 193 because you have to make a box plot and whiskers
The third and second answer
This
is equivalent to ![\rm 1-P(Z\leq 1.7)](https://tex.z-dn.net/?f=%5Crm%201-P%28Z%5Cleq%201.7%29)
It is given that the ![\rm P(Z\geq 1.7)](https://tex.z-dn.net/?f=%5Crm%20P%28Z%5Cgeq%201.7%29)
It is required to find which statement is equivalent to ![\rm P(Z\geq 1.7)](https://tex.z-dn.net/?f=%5Crm%20P%28Z%5Cgeq%201.7%29)
The statements are:
![a) \ \rm P(Z\geq -1.7)\\b) \ \rm 1-P(Z\geq -1.7)\\c) \ \rm P(Z\leq 1.7)\\d) \ \rm 1-P(Z\leq 1.7)](https://tex.z-dn.net/?f=a%29%20%5C%20%20%5Crm%20P%28Z%5Cgeq%20-1.7%29%5C%5Cb%29%20%5C%20%5Crm%201-P%28Z%5Cgeq%20-1.7%29%5C%5Cc%29%20%5C%20%5Crm%20P%28Z%5Cleq%20%201.7%29%5C%5Cd%29%20%5C%20%5Crm%201-P%28Z%5Cleq%201.7%29)
<h3>What is a normal distribution?</h3>
It is defined as the continuous distribution probability curve which is most likely symmetric around the mean. At Z=0, the probability is 50-50% on the Z curve. It is also called a bell-shaped curve.
We have the ![\rm P(Z\geq 1.7)](https://tex.z-dn.net/?f=%5Crm%20P%28Z%5Cgeq%201.7%29)
We know that:
![\rm P(Z\leq a)=P(Z\geq -a)\\\rm P(Z\geq a)=P(Z\leq -a)](https://tex.z-dn.net/?f=%5Crm%20P%28Z%5Cleq%20%20a%29%3DP%28Z%5Cgeq%20-a%29%5C%5C%5Crm%20P%28Z%5Cgeq%20%20%20a%29%3DP%28Z%5Cleq%20%20%20-a%29)
If we compare statement (a) and statement (c), we will see these options are not equivalent to ![\rm P(Z\geq 1.7)](https://tex.z-dn.net/?f=%5Crm%20P%28Z%5Cgeq%201.7%29)
For statement (b) if we plot the graph for the given statement we will get the negative area of the bell curve hence it is also incorrect.
For statement (d) if we plot the graph for the given statement we will get the positive area which is equivalent to the
Thus, the
is equivalent to ![\rm 1-P(Z\leq 1.7)](https://tex.z-dn.net/?f=%5Crm%201-P%28Z%5Cleq%201.7%29)

ghis is the answer hope it is correct if not please commend
Answer: R12.20
Step-by-step explanation:
VAT in South Africa is 15% so if the flat rate is R93.57, the VAT amount can be found by finding the pre-tax flat rate:
93.57 = x + 0.15x
1.15x = 93.57
x = 93.57/1.15
x = R81.37
VAT is 15% of R81.37:
= 15% * 81.37
= R12.20
