Whats the area of a polygon with vertices A(2,3) B(12,3) C(6,0) and D(2,0)

1 answer:

6 0

This shape is trapezoid

top of the trapezoid is 10 (12-2)

and the bottom is 4 (6-2)

the height in 3 (3-0)

so the area will be
$((10+4) \times 3) \div 2 \\ = (14 \times 3) \div 2 = 42 \div 2 \\ = 21$
the area is 21

A bag contains 135 marbles some white and some transparent. The ratio of white marbles to transparent ones is 3 : 6. How many wh

Setler [38]

Answer:

Number of white marbles in the bag = 45

Step-by-step explanation:

Total number of marbles in the bag = 135

Ratio of white marble to transparent ones = 3 : 6

Let number of white marbles be $=3k$

Then number of transparent marble will be $=6k$

Total number of marbles will be $=3k+6k=9k$

So we have.

$9k=135$

Dividing both sides by 9.

$\frac{9k}{9}=\frac{135}{9}$

∴ $k=15$

∴ Number of white marbles in the bag = $3k=3\times15 = 45$

aalyn [17]

Answer:

If a person is randomly selected from this group, the probability that they have both high blood pressure and high cholesterol is P=0.25.

Step-by-step explanation:

We can calculate the number of people from the sample that has both high blood pressure (HBP) and high cholesterol (HC) using this identity:

$N(\text{HBP or HC})=N(\text{HBP})+N(\text{HC})-N(\text{HBP and HC})\\\\\\ N(\text{HBP and HC})=N(\text{HBP})+N(\text{HC})-N(\text{HBP or HC})\\\\\\ N(\text{HBP and HC})=15+25-30=10$

We can calculate the probability that a random person has both high blood pressure and high cholesterol as:

$P(\text{HBP and HC})=\dfrac{10}{40}=0.25$
