Nolan watched a beetle on the sidewalk. It crawled 7/12 of a yard, then rested for a bit, and then crawled 1/4 of a yard farther

liberstina [14]

D, because 1/4 is equivalent to 4/12 and 7/12+4/12=11/12 which is equivalent to 5/6

Answer:

SAS postulate

Step-by-step explanation:

AD (common)

AC = BD (both are diameters)

Angle COD = Ange AOD (vertically opposite angles)

Angle CAD = Angle BAD (angle on the circumference is half the angle at the centre)

Therefore, ABD and DCA are congruent by SAS postulate

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.
