Answer:

Yes

Because

$\frac{pn}{kr} = \frac{pt}{kg} = \frac{tn}{gr} = \frac{1}{2}$

Also all angles are equal

Is the perimeter and area of the square always the same?

avanturin [10]

I think it would be because say you have a square and all the sides are 4. If you add all the sides you would get 16 for the perimeter. If you do 4 x 4 you would get 16 as the area. So i think they are the same but i am sometimes stupid so dont just take my word on it.
Hope this helps! :)

Solve, using the substitution method.

Phoenix [80]

14-4x=2y
divide both sides by 2
7-2x=y
subsitute 7-2x for y
7-2x+2x=7
add like terms
7=7
true
therefor these 2 equations are the same and there are an infinite number of equations

answer is C

Major league baseball salaries averaged $1.5 million with a standard deviation of $0.8 million in 1994. suppose a sample of 100

seropon [69]

Answer: The probability that the avg. salary of the 100 players exceeded $1 million is approximately 1.

Explanation:

Step 1: Estimate the standard error. Standard error can be calcualted by dividing the standard deviation by the square root of the sample size:

$SE=\frac{0.8}{\sqrt{100}}=\frac{0.8}{10} = 0.08$

So, Standard Error is 0.08 million or $80,000.

Step 2: Next, estimate the mean is how many standard errors below the population mean $1 million.

$\frac{1 - 1.5}{0.08}$

$=-6.250$

-6.250 means that $1 million is siz standard errors away from the mean. Since, the value is too far from the bell-shaped normal distribution curve that nearly 100% of the values are greater than it.

Therefore, we can say that because 100% values are greater than it, probability that the avg. salary of the 100 players exceeded $1 million is approximately 1.
