Answer:
standard deviation = ±0.4667
Step-by-step explanation:
In Normal distribution, approximately 68% of all the data lie within 1 standard deviation from the mean, approximately 95% of all the data lie within 2 standard deviations from the mean and approximately 99.7% of all the data lie within 3 standard deviations from the mean.
Therefore, for a confidence interval of 99.7% the standard deviation of the x¯ must be 3 standard deviations from the mean,
3σ = ±1.4
σ = ±1.4/3
σ = ±0.4667
Therefore, 0.4667 is the standard deviation that x¯ must have so that 99.7% of all samples give an x¯ within 1.4 point of μ.
Use proportions.
2 chocolate chips : 6 peanuts = ? chocolate chips : 108 peanuts
Find the scale factor of the information that matches. In this case it would be 108 peanuts divided by 6 peanuts. Then use this scale factor to multiply 2 chocolate chips by to get your answer.
SF: 108 <span>÷ 6 = 18
18 x 2 = 36 chocolate chips
2 chocolate chips : 6 peanuts = 36 chocolate chips : 108 peanuts
ANSWER: If there are 108 peanuts in the mix, there will be 36 chocolate chips in the mix.</span>

Answer:
Adjacent angles and not a linear pair
Step-by-step explanation:
They are adjacent because they are located right next to each other and share a common side. They aren't linear because both angles don't sit on a straight line by themselves. <DGB is also on that line; therefore, <AGE and <EGD and <DGB would add up to 180 degrees.
