Answer:

1. 60% (decrease by 40%)

3. 30% (decrease by 70%)

5. 250% (Increase by 150%)

7. 40% (Decrease by 60%)

9. 171.4% (increase 71.4%)

11. 152.6% (Increase by 52.6%)

Step-by-step explanation:

1. 20x = 11 = 0.55 rounds to 0.6 => 60%

3. 56 x = 14 = 0.25 rounds to 0.3 => 30%

5. 18x = 45 = 2.5 => 250%

7. 126x = 48 = 0.38 rounds to 0.4 => 40%

9. 42x = 72 = 1.714 => 171.4%

11. 95x = 145 = 1.526 => 152.6%

Which of the following is true of the data represented by the box plot

zmey [24]

Answer:

The data is skewed to the bottom and contains an outlier.

Step-by-step explanation:

1. Test for outlier

An outlier is a point that is more than 1.5IQR below Q1 or above Q3.

IQR = Q3 - Q1 = 74 - 51 = 23

1.5 IQR = 1.5 × 23 = 34.5

51 - 15 = 36 > 1.5IQR

The point at 15 is an outlier.

2. Test for normal distribution

The median is not in the middle of the box.

Rather, it cuts the box into two unequal parts, so the data does not have a normal distribution.

3. Test for skewness

The longer part is to the left of the median, so the data is skewed left.

Int he figure below find AC

Ahat [919]

Given :-

Two triangles with their two angles equal .

To Find :-

Measure of AC .

Answer :-

Here in ∆ABC and ∆EDC ,

$\angle$ CAB = $\angle$ CED (given )
$\angle$ CBA = $\angle$ CDE (given)

Therefore by AA similarity criterion , we can say that ∆ABC ~ ∆EDC . Also we know that corresponding sides of similar triangles are proportional . So ,

→ AC/EC = BC/DC

→ AC/9 = 8/12

→ AC = 8/12 * 9

→ AC = 6

Hence the measure of side AC is 6 .

I hope this helps.
