1/6d + 2/3 = 1/4(d - 2)
1/6d + 2/3 = 1/4d -1/2
2/12d + 4/6 = 3/12d -3/6
4/6 = 1/12d - 3/6
7/6 = 1/12d
7/6 x 12/1 = d
84/6 = d
14 = d
So d = 14.
Hope I helped.. ^^

The standard deviation of the set is 5.2
To find standard deviation, we take the square root of the variance.
-12/3 • 17/18 equals -3 7/9 as a mixed number (simplified). the non-simplified one is -3 42/54
Answer:
2.2
Step-by-step explanation:
To find a, you use a formula called the law of cosines:
The law of cosines tells us:
a^2 = b^2 + c^2 - 2bc cosA
So lets plug in the values:
a^2 = 4^2 + 3^2 -2(4)(3)cos(32)
a^2 = 25-24cos32
a^2 is roughly equal to 4.97
therefore a roughly equal to 2.2
