Answer:

AE = CE = 12 in

Step-by-step explanation:

Angles BDF and BCF are base angles of their respective isosceles triangles. That means the a.pex angle of each, DBF and ABC respectively is ...

180° -2×30° = 120°

In your diagram, BC is 120° from the -x axis, so is 60° from the +x axis. It bisects the angle DBE. Similarly, BE is 120° from the +x axis, so is 60° from the -x axis. It bisects angle ABC. In an isosceles triangle, the a.pex angle bisector is an altitude and is the perpendicular bisector of the base segment. Any point on that line is equidistant from the base vertices.

Point C lies on the perpendicular bisector of DE, so CD ≅ CE = 12 in.

Point E lies on the perpendicular bisector of AC, so EC ≅ EA = 12 in.

The measurements of interest are ...

AE = CE = 12 in.

<em>Additional comment</em>

Point F serves no purpose except to confuse the issue. Each of the angles that reference point F could be described equally well using a different point:

∠BDF = ∠BDE

∠BCF = ∠BCA

This makes it more obvious that the triangles of interest are similar.

Answer: (D) The external validity of the study

Explanation:

The external validity is the type of study which basically depicts that the concept of the study result must be meaningful. The external validity mainly apply in the conclusion in the scientific concepts and study about the main context.

External validity is the type of validity in which we extent the result of the study across the different types of situations, times and people. In mathematics, the external validity concept is applicable for determining the statistical and the various computational methods.

The price of a flight was increased by 3% to £650. What was the price before the increase? Give your answer to the nearest penny

Marta_Voda [28]

Answer:

£631.07

Step-by-step explanation:

Increasing a value by 3% is the same as taking 103% of it - you have the original price (100%) plus an additional 3% of it. Let's call the original price here p. We're told that after a 3% increase, the price goes up to £650. Put another way: 103% of p is £650. In equation form:

$1.03p=650$

To solve for p, we can simply divide both sides of our equation by 1.03 to get

$p=650/1.03\approx631.07$

So our orignal amount, to the nearest penny, was £631.07

Amiraneli [1.4K]

The question is incomplete. The compete question is :

Saul decides to use the IQR to measure the spread of data. Saul calculates the IQR of the data set to be 27. Saul asks Jasmine to check his work. Saul copies the data in numerical order from least to greatest for Jasmine. 25, 30, 50, 50, 50, 50, 56, n, 250. What is the value of n that will make the IQR of the data set equal to 27?

Solution :

The inter quartile range is being measured as : 3rd quartile - 1st quartile

The 1st quartile = 25% mark

The 3rd quartile = 75% mark

The data set as given in the question is :

25, 30, 50, 50, 50, 50, 56, n, 250

Therefore, the total number of the sample = 9

And the median is = 50

The median separates the given data sets into two equal halves-- that is the upper half and the lower half.

Let the middle of a lower half is the 1st quartile be $Q_1$
