Answer:
0.4060
Step-by-step explanation:
To calculate the sample proportion, phat, we take the ratio of the number of preferred outcome to the total number of trials ;
Phat = number of times coin lands on head (preferred outcome), x / total number of trials (total coin flips), n
x = 406
n = 1000
Phat = x / n = 406/ 1000 = 0.4060
Your subtracting 3x from 5x: 5x-3x
This is so you only have a variable on one side

Step-by-step explanation:
Answer: 11
Step-by-step explanation:
Ok so I'm guessing you are wondering what is the value of the 3 equal sides. First you subtract 7 from 40 and get 33. Then divide 33 by 3 and you'll get 11.
40-7=33
33/3=<u>11</u>
Answer:
A=b(1/2b-1)
112ft^2
Step-by-step explanation:
-Write the equation in factored form: A= b (1/2 b -1 )
-Supposed the base of the flower bed is 16 feet. What will the area be:
b=16 feet
Formula is A=1/2(1/2b-1)
Replace the b with 16
A=1/2 (16)^2 - 16
A=1/2 (256)-16
A=256/2 - 16
A=128-16
A=112 ft^2
The area will be 112 ft^2
