GRADE 6 MATHEMAT 12. Look at the data set. 12, 34, 27, 27, 36, 42, 15, 28, 32, 47, 30 Which statement is true about the data set

adelina 88 [10]

The statement is true because it's going in accending order.

the prerquartute 11 question

Step 1: Put the numbers in order.

1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.

Step 2: Find the median.

1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.

Step 3: Place parentheses around the numbers above and below the median.

Not necessary statistically, but it makes Q1 and Q3 easier to spot.

(1, 2, 5, 6, 7), 9, (12, 15, 18, 19, 27).

Step 4: Find Q1 and Q3

Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.

(1, 2, 5, 6, 7), 9, ( 12, 15, 18, 19, 27). Q1 = 5 and Q3 = 18.

Step 5: Subtract Q1 from Q3 to find the interquartile range.

18 – 5 = 13.

EastWind [94]

Answer:

<h2>A = 16.5 square units</h2>

Step-by-step explanation:

It's the right triangle.

The formula of an area of a right triangle:

$A=\dfrac{(leg)(leg)}{2}$

Look at the picture.

We have

$leg=3,\ leg=11$

Substitute:

$A=\dfrac{(3)(11)}{2}=\dfrac{33}{2}=16.5$

A landowner wants to find the distance d across a pond. The two overlapping right triangles are similar . Using the measurements

Leni [432]

Answer:

96 m

Step-by-step explanation:

It is given that the two overlapping triangles are similar in the figure.

The landowner wishes to find the distance across the pond. The distance is d.

From the figure, since the two triangles are similar, therefore we can write :

$\frac{d}{(24+40)}=\frac{60}{40}$

$\frac{d}{64}=\frac{60}{40}$

$d = \frac{60}{40} \times 64$

$d = \frac{6}{4} \times 64$

d = 6 x 16

= 96 m

Therefore, the distance across the pond is d = 96 m
