Answer:

160 m²

384 m²

Step-by-step explanation:

The area of a trapezium is given by :

A = 1/2(a + b)h

h = height ; a and b = lengths

From the diagram :

A = 1/2(12 + 20)10

A = 1/2(32)10

A = 16 * 10

A = 160 m²

2.)

Area of parallelogram = base * height

Base = 24 ; h = 16

A = 24 * 16

A = 384 m²

What is the perimeter of the shape below if 1 square is equal to 1 square foot

Radda [10]

The base, b, of a two-dimensional figure can be any side. The height, h, is the measure of a perpendicular line segment from the base to the top of the figure. Area is the number of square units needed to cover a flat surface without gaps or overlaps. A square unit is a square that is 1 unit long and 1 unit wide. To find the area of a figure, count the number of square units inside the figure. im sure thats right . now

In a survey of 200 professors at Gotham University, professors were asked, “Regarding your weight, do you think you are: About r

DochEvi [55]

The probability that a randomly selected professor is female and feels "About Right" is 0.40

The distribution table :

____About right _ Oweight _ Uweight __ Total

Female _ 80 _____ 39 ______ 3 _______ 122

Male ___ 52 _____ 10 ______ 16 _______ 88

Total ___ 132 ____ 49 ______ 19 _______ 200

Oweight = Overweight

Uweight = Underweight

Recall :

Probability = required outcome / Total possible outcomes

Probability that a selected professor is female and feels 'About right' :

Required outcome = number of female professors who feels 'About right' = 80

Total number of professors = 200

Hence,

P(Female and 'About right') = 80/200 = 0.40

How to find nth term of a sequence in math?

worty [1.4K]

Salutations!

To find the nth term, you will be needing a formula.

$a +(n-1) *d$

a stands for the first term (first number in the sequence)

d stands for the difference between two terms. (always remember to subtract from the 2nd term to the 1st term)

and the n is what we are going to find

so in your sequence: 5, 10, 15, 20

5 is a (as it is the first term)

d would be 5 ( 10 -5 =5)

$a+(n-1)*d$

$5+ (n-1) *5$

$5+5n-5$

$5n+0$

your nth term is $5n+0$

Hope this helps!

Have a great day!
