Answer:
8cm
Step-by-step explanation:
First you must know that the diameter of the semi-circular patio is equal to the length of one side of the square
Area of a semi circle = πr²/2
25.12 = πr²
25.12 = 3.14r²/2
r² = 25.12(2)/3.14
r² = 16
r = √16
r = 4
Get the diameter
d = 2r
d =2(4)
d = 8cm
Hence the length of the side of the square is 8cm
Answer:
g=12
Step-by-step explanation:
substitute m for 6 and rewrite the equation
g = 6+6
g=12
Answer:
The distribution of sample proportion Americans who can order a meal in a foreign language is,

Step-by-step explanation:
According to the Central limit theorem, if from an unknown population large samples of sizes <em>n</em> > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:

The standard deviation of this sampling distribution of sample proportion is:

The sample size of Americans selected to disclose whether they can order a meal in a foreign language is, <em>n</em> = 200.
The sample selected is quite large.
The Central limit theorem can be applied to approximate the distribution of sample proportion.
The distribution of sample proportion is,

Answer:
25+x=y
Step-by-step explanation:
First, we start as 25, the number of cards he has in his collection. Then we add x, the cards he receive. The sum is y.
I think the answer is 300+20+8
and 400+7 :)
