<u>Answer-</u>
<em>Area of the triangle is </em><em>10 sq.units</em>
<u>Solution-</u>
We know that,
Taking,
(x₁, y₁) = (3, 3)
(x₂, y₂) = (3, -1)
(x₃, y₃) = (-2, -5)
Then putting these in the formula,
As area can not be negative, ignoring negative sign,
Answer:
x = 2.24
Step-by-step explanation:
I will ASSUME that the 15 represents the angle in degrees
We can make a similar triangle by adding the purple lines as shown.
Any triangle inscribed in a circle with one side as a diameter is a right triangle.
We know it is similar triangle because it shares two common angles, the right angle and the 75° angle at the far right. Then
z = 2Rsin15 = 2(16.7)sin15
x = zsin15 = 2(16.7)sin²15 = 2.237375756799...
Answer:
d. Some customers had more than one drink.
Step-by-step explanation:
The exact question is as follows :
Given - Hannah wants to simulate whether customers will choose a small, medium, or large drink, or no drink at a fast food restaurant. She decides to use digits from a random number table to represent the drink option a customer will order (0=no drink, 1=small drink, 2=medium drink, 3=large drink, ignore digits 4-9)
To find - Why does this NOT model the situation?
a. The choices are not equally likely to occur.
b. Some of the digits were ignored.
c. The choice are independent of each other.
d. Some customers had more than one drink.
Solution -
The correct option is - d. Some customers had more than one drink.
Reason -
If Customer order more than one drink, then also he has to order either of the digits.
So, Hannah can not be sure about the order that he wants single order or wants to repeat the order.
