Answer: 2 7/15

Step-by-step explanation: First, you make sure you have the same denominator on both of the fractions.

4/5 turns to 12/15 and 1/3 turns to 5/15

After that, then you do 12/15 - 5/15, which is 7/15.

Now you do 3 - 1.

Your answer should be 2 7/15.

I hope this helps you and I hope you have a blessed day!

In parallelogram FGHJ if m∡ GHJ=55˚ find m∡FGH

hodyreva [135]

Answer:

∠ FGH = 125°

Step-by-step explanation:

The consecutive angles in a parallelogram are supplementary, then

∠ FGH + ∠ GHJ = 180° , that is

∠ FGH + 55° = 180° ( subtract 55° from both sides )

∠ FGH = 125°

Answer:

No, this result is not surprising. It is a little bit more than one standard deviation above 20%

Step-by-step explanation:

Proportion of each color in the population (p) = 0.20

Sample size (n) = 20 Skittles

The standard deviation of a sampling distribution is determined by:

$\sigma = \sqrt{\frac{p*(1-p)}{n}}\\\sigma = \sqrt{\frac{0.20*(1-0.20)}{20}}\\ \sigma =0.089$

The difference between the observed proportion of 0.30, and the mean proportion of 0.20 is 0.10, which is just a little bit more than one standard deviation of 0.089. Therefore, this result is not surprising since it is a little bit more than one standard deviation above 20%.
