Answer:

The slope of AB is - 2,

Slope of BC is \frac{1}{2}

ABCD is trapezoid because one pair of opposite sides is parallel.

Step-by-step explanation:

Given vertices of quadrilateral ABCD,

A(−1, −1) , B(−3, 3) , C(1, 5) , and D(5, 2),

∵ Slope of a line passes through two points (x_1, y_1)(x

,y

) and (x_2, y_2)(x

,y

) is,

m=\frac{y_2-y_1}{xc_2-x_1}m=

xc

Thus, the slope of AB = \frac{3+1}{-3+1}=\frac{4}{-2}=-2

Slope of BC = \frac{5-3}{1+3}=\frac{2}{4}=\frac{1}{2}

Slope of CD = \frac{2-5}{5-1}=-\frac{3}{4}

Slope of DA = \frac{-1-2}{-1-5}=\frac{-3}{-6}=\frac{1}{2}

Since, when two line segment having the same slope then they are parallel to each other.

∴ BC ║ DA

A quadrilateral only having two parallel sides is called trapezoid,

Hence, ABCD is a trapezoid.

the mean of a distribution is 276 while the median is 231. which of these statements is likely to be true about the distribution
Verizon [17]

Answer:

Step-by-step explanation:Given that the mean distribution is 217, and the median is 291. This follows that given 217<291, it implies that most of the values lie to the left of the center of the distribution, hence the distribution will be positively skewed.

Hence,

the answer is:

b.) it is positively skewed

You roll a number cube and flip a coin.What is the probability of rolling a number less than 2 and flipping tails. Write your an
vesna_86 [32]

Answer:

1/6

Step-by-step explanation:

number cube 6 faces less than 2, only 2 possibilities, leaving us with a fraction of 2/6=1/3

tails is a 50 percent chance or 1/2

3/6 time 2/6

equals:

1/6

the probability of rolling a number less than 2 and flipping tails on a coin is 1/6

find probability of event a: number cube and multiply it by probability of event b: coin
