315/1575 write the prime factorization of the numerator and denominator

1 answer:

Ivan3 years ago

3 0

Numerator:
315= 3^2* 5* 7

Denominator:
1575= 3^2* 5^2* 7

Therefore,
315/1575
= (3^2* 5* 7)/ (3^2* 5^2* 7)
= 1/5

Hope it helps.

Which of the following points lies on the circle whose center is at the origin and whose radius is 13?

Alexxandr [17]

any point that is on the circle will have a distance of "radius" units, namely 13 units, since the radius is just that.

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ \stackrel{origin}{(\stackrel{x_1}{0}~,~\stackrel{y_1}{0})}\qquad (\stackrel{x_2}{-5}~,~\stackrel{y_2}{12})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{(-5-0)^2+(12-0)^2}\implies d=\sqrt{(-5)^2+12^2} \\\\\\ d=\sqrt{25+144}\implies d=\sqrt{169}\implies d=13$

Help please! i need to find the restrictions to this expression

jarptica [38.1K]

Answer:

x = 7, x = $\frac{-1}{5}$

Step-by-step explanation:

A restriction can only be found in the denominators and this is when x is a certain number that when plugged in, makes the expression 0 (this makes it undefined, which you cannot have).

Since we are only looking at the denominator, you can just ignore the numerator:

(x - 7) (5x + 1)

To find the restrictions, you must set them equal to 0:

x - 7 = 0

5x + 1 = 0

Then, solve:

x - 7 = 0 5x + 1 = 0

+ 7 + 7 - 1 - 1

________ ________

x = 7 5x = -1

x = $\frac{-1}{5}$

If you plug these numbers in, the total outcome would come out to be 0, making the expression undefined, proving that these are the restrictions of the expression.

The proportion of the total area under a normal curve between two z-scores corresponds to the ______ of that range of scores.

omeli [17]

Answer:

For any normal distribution, the mean and the median will have the same value. For any normal distribution, the proportion corresponding to scores greater than z = +1.00 is exactly equal to the proportion corresponding to scores less than z = -1.00.
