In the diagram below, DE and EF are tangent to O. Which equation could be solved to find X, the measure of DF.

Brut [27]

Answer:

The answer to your question is letter D

Step-by-step explanation:

Formula

m∠E = $\frac{1}{2} ( DGF - DF)$

Data

m∠E = 48°

DGF = 228°

DF = x°

Substitution

48° = $\frac{1}{2} ( 228° - x°)$

Solution

2(48) = 228 - x°

96 = 228 - x°

96 - 228 = - x°

- 132 = - x°

x° = 132°

Which statement correctly compares the mean number of students for the data in the plots?

satela [25.4K]

Answer:

"There are about 2 more students in each class at Oak Middle School than at Poplar Middle School."

Step-by-step explanation:

We need to compute the mean for each.

Poplar Middle School:

Lets list the numbers

20,20,20,21,21,21,21,21,22,22,22,22,22,22,22,23,23,23,23,24

The average is sum of all divided by number of numbers, that will be:

435/20 = 21.75

Oak Middle School:

The numbers are:

20,21,21,22,22,23,23,23,23,24,24,24,25,25,26,26,27,27,28,29

The average is sum divided by number of numbers, that will be:

483/20 = 24.15

The difference in mean is:

24.15 - 21.75 = 2.4

We can say, that is about 2 more students in Oak Middle School, correct answer choice is "2nd answer choice" - "There are about 2 more students in each class at Oak Middle School than at Poplar Middle School."
