Answer: Length = 15 inches
Width = 12 inches
Step-by-step explanation:
The painting is rectangular.
Let L represent the length of the painting.
Let W represent the width of the painting.
Area of a rectangle = LW
Marisol is panting on a piece of canvas that has an area of 180 square inches. It means that
LW = 180- - - - - - - - - - -1
The length of the painting is 1 and 1 fourth times the width. It means that
L = 1.25W
Substituting L = 1.25W into equation 1, it becomes
W(1.25W) = 180
1.25W² = 180
W² = 180/1.25
W² = 144
W = √144
W = 12 inches
L = 1.25W = 1.25 × 12
L = 15 inches
Answer: a) 0.2222, b) 0.3292, c) 0.1111
Step-by-step explanation:
Since we have given that
Let the probability of getting head be p.
Since, its head is twice as likely to occur as its tail.
a)If the coin is flipped 3 times, what is the probability of getting exactly 1 head?
So, here, n = 3
Now,
b)If the coin is flipped 5 times, what is the probability of getting exactly 2 tails?
2 tails means 3 heads.
So, it becomes,
c)If the coin is flipped 4 times, what is the probability of getting at least 3 tails?
Hence, a) 0.2222, b) 0.3292, c) 0.1111
Answer:
0.125kg
Step-by-step explanation:
an equation can be made from teh problem
f(x)=1(0.5)^(x/5.3)
x is the amount of years
plug in 15.9 for x
f(15.9)=0.125
Answer:
<h2>16.666...%</h2>
Step-by-step explanation:
Let y be the first number
and x be the second number
then
y=x+20%x = (120/100)x
y=(120/100)x ⇔ x=(100/120)y
let‘s write x=(100/120)y in the form x=(p/100)y where p is a number to find
100/120=p/100 ⇔ p=(100×100)/120 = 83.333.....
then x = (83.333/100)y
since 83.333 = 100 - 16.666
then x = y - 16.666%y
