Answer: A = ≈28.55 cm²
Step-by-step explanation:
It is drawn as if it should be a triangle minus a rectangle with an area of
½(10)(13) - (7)(6) = 23 cm²
However it is not to scale.
The angle on the right side is
θ = arctan10/13 = 37.56859...°
Meaning the right triangle has a height of
h = 4tan37.56859 = 3.07692 cm
So the right triangle has an area of
Ar = ½(3.07692)(4) = 6.15384... cm²
The left hand side consists of a triangle over a rectangle
The height of the triangle is 4, the base is is 4/tan37.56859 = 5.2 cm
so the left area is
(2)(6) + ½(5.2)(4) = 22.4 cm²
So the sum of the areas of the two enclosed shapes is
A = 22.4 + 6.15384... = 28.55384... ≈28.55 cm²
Since we aren't given Jose's age (or the question asked here is incomplete), we can assume we are looking for an expression for "49 decreased by twice Jose's age."
The answer would be:
49 - 2x
where x is Jose's age. Hope this helps.
Answer: 6 customers
Step-by-step explanation:
From the pie chart,
Given;
Cookies and creams = 24%
Mint chocolate chips = 28%
Straw berry = 20%
Vanilla = 12
Butterscotch = 16
No of customers = 25
Solution
How many of the 25 customers named cookies and cream
= 25 x 24/100
= 25 x 0.24
= 6 customers
6 customers named cookies and cream
A statistic and a parameter are very similar. They are both descriptions of groups, like “50% of dog owners prefer X Brand dog food.” The difference between a statistic and a parameter is that statistics describe a sample. A parameter describes an entire population.
