Answer:
0.9544 or 95.44%
Step-by-step explanation:
The empirical rule indicates that the percentage of data falls in one standard deviation, 2 standard deviation and 3 standard deviation are 68.26%,95.44% and 99.73%
We are given that x1=52, x2=76 ,mean=64 and standard deviation=6
mean+sd= 64+6=70
mean-sd=64-6=58
mean+2*sd=64+12=76
mean+2*sd=52
x1 and x2 are within 2 standard deviation and the percentage of data lies between two standard deviation is 95.44%.
14 Bc 6.5 + 6.5 = 12 + 1/2+1/2 = 13
In this, we have to see if we can get a common ratio between both of the triangles. Lets start by dividing 5 from 10. From this, we get 2. If we divide 7 from 14, we also get 2, so we know that they are similar. Therefore, both of them are similar because AB/FD = AC/FE
Answer:
x = 8
Step-by-step explanation:
Formula for sum of interior angles is 180(n - 2)
For a 5 sided polygon the sum is;
180(5 - 2) =540°
The supplement of ∡ 59° = 180° - 59° = 121°
The supplement of ∡ 77° = 180° - 77° = 103°
The supplement of ∡ 66° = 180° - 66° = 114°
The supplement of ∡ 62° = 180° - 62° = 118°
The sum of the polygon is:
121° + 103° + 114° + 118° + (180 - 12x)° = 540°
456° + (180 - 2x)° = 540°
(180 -12x)° = 540° - 456° = 84°
12x = 180° - 84° = 96°
x = 96/12 = 8
