Mrs. Alberts has two seventh grade math classes this year. They took their final exam, and Mrs. Alberts just finished grading them. She made a box-and-whisker plot for each class in order to compare their results.

Analyze the box-and-whisker plots from above and then select the following comparative inferences that are true. Select all that apply.


1. The interquartile range of Class A is about twice as large as the interquartile range of Class B.
2. There is very little overlap in the two data sets.
3. The median of Class A is about 5 points higher than the median of Class B.
4. The range of Class B is about 12 points less than the range of Class A.
5. A student in Class B had the highest score of both classes.
6. In general, the students from Class B scored better than the students from Class A.

Answer:

12

Step-by-step explanation:

We can try and get both sides to have a common denominator. If we multiply the left side by 4, we get 12/16=x/16. Here, it is clear that x=12.

Answer:

x is equal to 12/16

Step-by-step explanation:

If you divide 12/16 by 4 you will realize that it is equal to 3/4. Therefore x is equal to 12. That is a really explanation, but hope it helps!

The triangles ΔABC ≈ ΔBDC and ΔABC ≈ ΔADB are similar triangles. Then the correct options are B and C.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

In a right-angle triangle, the measure of one angle will be 90 degrees.

If any two angle of the triangles are congruent, then the triangles will be a similar triangle.

In triangle ΔABC and ΔADB, we have

∠A = ∠A (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔADB are similar triangles.

In triangle ΔABC and ΔBDC, we have

∠C = ∠C (common angle)

∠B = ∠D = 90° (right angle)

Then the triangle ΔABC and ΔBDC are similar triangles.

Then the correct options are B and C.

The diagram is given below.

Answer:

7.37%

Step-by-step explanation:

9/20 x 8/19 x 7/18 = 7/95 (simplified) which is 7.37%

(1) Repetition allowed : There are 4 choices for both positions, so 4 × 4 = 16 2-digit numbers can be formed. (2) Repetition not allowed : There are 4 options for tens position, and three options for ones position. Therefore, 4 × 3 = 12 2-digit numbers can be formed.

Answer:

B

Step-by-step explanation:

Obviously the population is increasing.

(3297.44-2568.05)/2568.05 = .284... = 28.4% increase

(4234-3297.44)/3297.44 = .284 ... = 28.4% increase

B is the answer

Answer:

x = 7

Step-by-step explanation:

The image below shows the relationship between secants chords and tangents.

Imagine that the letters in the image represent the numbers in the actually problem

E would equal 9

C would equal 12

and A would equal x

We would then use the same formula C² = E * ( E + A ) to solve for x , but once again instead of using letters we use the numbers in the problem

We would have 12² = 9( 9 + x )

we now solve for x

Step 1 simplify and distribute

12²=144

9 * 9 = 81

9 * x = 9x

we would then have 144 = 81 + 9x

step 2 subtract 81 from each side

144 - 81 = 63

81 - 81 cancels out

we now have 63 = 9x

step 3 divide each side by 9

63 / 9 = 7

9x / 9 = x

we're left with x = 7
