Answer:

Area of Triangle

= 135 sq cm

Area of Shaded

= 135 sq cm

Step-by-step explanation:

There is a parallelogram here and a triangle both have the same base and height.

Area (triangle)=1/2bh

Area (parallelogram)

=bh

Subtract to find the shaded region.

Area (parallelogram)

= 18 × 15

= 270

Area(triangle)

= 1/2 × 18 × 15

= 135

Area(shaded)

= 270 - 135

= 135

The shaded area is 135 square cm

Answer:

Step-by-step explanation:

Area of the triangle

A = b*h/2

b = 18

h = 15

Area = 18*15/2

Area = 135

Area of Parallelogram

A = b * h

b = 18

h = 15

Area =  18 * 15

Area = 270

Note: The parallelogram = 2 * Area of Triangle.

A poll of all 2000 students in a high school found that 94% of its students owned cell phones.
LekaFEV [45]

Answer: F. Parameter, because the data set of all 2000 students in a high school is a population.

Step-by-step explanation:

Parameters is a variable or measure that is calculated from the entire population of data while a statistic is done from a sample of the data.

The question notes that the poll was done on <u>all 2,000</u> students in a high school. This means that the poll is a Parameter because it was done on the entire population of the high school.

Urgent help!
Alchen [17]

Answer:

(i) 80-x

(ii) S(x) = 40 - 0.10x

(iii) $36.5

Step-by-step explanation:

Given that:

1. Total Number of fruits = 80

2. Number of mangoes = x

3. Both mangoes and oranges are there in the basket.

Solution (i):

Only mangoes and oranges are there in the basket and the basket is full.

so, Number of mangoes + Number of oranges = Total number of fruits

x + Number of oranges = 80

Number of oranges = 80 -x

Solution (ii):

<u>Given:</u>

Cost of an orange = 50 cents = $0.50

Cost of a mango = 40 cents = $0.40

Cost for x mangoes = \$ 0.40x

Cost for (80-x) oranges = \$ 0.50 \times (80-x)

\Rightarrow S(x) = 0.50 (80-x) + 0.40x\\\Rightarrow S(x) = 40 -0.50x + 0.40x\\\Rightarrow S(x) = 40 - 0.10x

Solution (iii):

Put value of x = 35 in S(x)

S(35) = 40 - 0.10 (35)\\\Rightarrow S(35) = 40 - 0.35\\\Rightarrow S(35) =\$ 36.5

Hence, answers are:

(i) 80-x

(ii) S(x) = 40 - 0.10x

(iii) $36.5

What is the length of PQ¯¯¯¯¯?
timofeeve [1]
Since you don't have any angle and its opposite side, you cannot establish the ratio for the law of sines, so you must use the law of cosines.

c^2 = a^2 + b^2 - 2ac \cos C

Let's change it for this problem.

r^2 = p^2 + q^2 - 2pq \cos R

r^2 = 9^2 + 6^2 - 2(9)(6) \cos 34^\circ

r^2 = 9^2 + 6^2 - 2(9)(6) \cos 34^\circ

r^2 = 27.46

r = 5.24

PQ = 5.2~km
