I think this is a least common multiple question

So they would all arrive on day 504, (which probably is a few years)

8 = 2 × 2 × 2

18 = 2 × 3 × 3

21 = 3 × 7

I might be right I might be wrong, IM not positively sure but yknow

10bf + 25bg – 21p – 14pq<br> Quadratic factorisation
Leni [432]

The problem 10bf + 25bg – 21p – 14pq cannot be factored because it cannot be simplifed further. This is because there are no common factors between in any of the terms.

. A recent report in a women magazine stated that the average age for women to marry in the United States is now 25 years of age
Setler [38]

Answer: 0.0136

Step-by-step explanation:

Given : Mean : \mu=25

Standard deviation : \sigma=3.2

Sample size : n=50

The formula to calculate the z-score :-

z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}

For x = 24

z=\dfrac{24-25}{\dfrac{3.2}{\sqrt{50}}}=-2.21

The p-value = P(z\leq-2.21)= 0.0135526\approx0.0136

Hence, the probability that the sample mean age for 50 randomly selected women to marry is at most 24 years = 0.0136

The output is four times the input
juin [17]
O=4i (is that was you were asking about) 

edit: sorry that wasn't very detailed say if the input is 4 the output will be 16 or if the input is 100 the output will be 400. So mainly what ever the input is multiply it by 4.

I hope this helps :)

Write an equation of the circle with center (-7,4) and radius 11.
olga_2 [115]

Answer: (x+7)^2 + (y-4)^2 = 121  or  (x+7)^2 + (y-4)^2 = 11^2

Step-by-step explanation:

Equation of the circle is:

(x-h)^2+(y-k)^2=r^2 , which is the center (h,k) and the radius r^2

-Place the center (-7,4) and radius 11 onto that equation:

(x+7)^2+(y-4)^2=121 (if simplified radius needed)

or

(x+7)^2(y-4)^2=11^2
