Answer: 28.4

Step-by-step explanation:

Given : A set of data with a mean of \mu= 45and a standard deviation of  \sigma=8.3 is normally distributed.

Now, the value that is –2 standard deviations away from the mean is given by :-

x=\mu-2\sigma\\\\\Rightrrrow\ x=45-2(8.3)\\\\\Rightarrow\ x=45-16.6\\\\\Rightrrrow\ x=28.4

Hence, the value that is –2 standard deviations away from the mean. = 28.4

A rectangle ahs a long side of a length 8.5 cm its perimeter is 24cm work out the length of the shorter side
Phantasy [73]

Answer:

Width (length of shorter side) = 3.5 cm.

Step-by-step explanation:

L = 8.5 cm

perimeter, P = 24 cm

2(L+W) = 24

substitute L = 8.5

2(8.5+W) = 24

8.5 + W = 24/2 = 12

W = 12 - 8.5 = 3.5 cm
