Answer:
64 ft
Step-by-step explanation:
The perimeter of the drawing is
2(3.25 in. + 4.75 in.) = 16 in.
Now we use the scale to find the real perimeter.
1 in. : 4 ft
16 * 1 in. : 16 * 4 ft
16 in. : 64 ft
The real perimeter is 64 ft.
Answer:
$416,660
Step-by-step explanation:
X = original price of condo
15% of X = 0.85x = $354,161
x = 354,161/0.85
x = $416,660
M<2 = m<3
but
m<1 + m<2 = 180
4x + 36 + <span>3x – 3 = 180
7x + 33 = 180
7x = 147
x = 21
m<2 = </span><span>3x – 3
m<2 = 3(21) - 3
m<2 = 63 - 3
m< 2 = 60
m<3 = m<2 = 60
answer
</span><span>60°</span>
Answer: 0.923
Step-by-step explanation:
Let A be the event an Internet user posts photos that they have taken themselves, and B be the event an Internet user posts videos that they have taken themselves.
Pew Research Center finds that
P(A)=0.52 P(b)=0.26, and P(A or B)=0.54.
To find : P(A|B)
Since , 
i.e. 

Now, using conditional probability formula ,

Hence, the conditional probability that an Internet user posts photos that they have taken themselves, given that they post videos that they have taken themselves = 0.923
