The value of a data point that is -2 standard deviations from the mean
so, 40.6 to 65.4.
<h3>What is the empirical rule?</h3>
According to the empirical rule, also known as the 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95%, and 99.7% of the values lies within one, two, or three standard deviations of the mean of the distribution.
From the empirical rule, we know that for 95% we are in 2 standard deviations of the mean. so:
= 53- 6.2- 6.2
= 40.6
The value of a data point that is -2 standard deviations from the mean
53 + 6.2 + 6.2
= 65.4

Answer:
cos A= 5/13
tan A= 12/5
Step-by-step explanation:
The units digit of the given exponential expression will be 6
<h3>Determining the units digit of an exponential expression</h3>
From the question, we are to determine the units digit of the given exponential expression
The given exponential expression is
4⁸⁰⁰
We know that
4¹ = 4
4² = 16
4³ = 64
4⁴ = 256
4⁵ = 1024
4⁶ = 4096
From above, we can observe that the units digit of the odd exponents is 4 while the units digit of the even exponents is 6.
The exponent of the given expression is 800. 800 is an even number.
Hence, the units digit of the given exponential expression will be 6

Answer:
Yemen was a poor country with a government widely acknowledged to be corrupt, with a large amount of weapons in private hands. By 2011, the country was already facing challenges from al Qaeda-linked militants and separatists in the south and Zaydi Shia rebels in the north.
