Just divide:

100 / 3 - 50 / 3 =17. Round to the next whole integer. That is how many numbers are divisible by 3.

51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99.

a fish with no eye is a fish with no eye

(eye and i are two different things the joke is soppused to be i but you said eye therfore it is a fish with no eye)

(however you said eye as in the singular eye therfor the fish was a cyclops)

The short answer is yes

Take any number, say 36

Work out the prime facrtors of 36

9*4=39

3*3*2*2=36

any number that you can get bu multiplying any of thes prime factors together will also be a factor of 36..

so

2

3

2*2

2*3

2*2*3

3*3

3*2*2

3*3*2

3*3*2*2

Yes.

If integer n is exactly divisible by 9 then it can be expressed as n = 9*m where m is another integer.

This means that n/3 = 9*m/3 → 3*m, an integer.

.

a)  The range is simply the difference between the largest and the smallest.

b)  I'm sure you can add them up to find Σx and add up the squares to find Σx² by yourself!

c)  The sample variance is \(s^2=\frac{\sum{(x-\mu)^2}}{n-1}\quad\text{ where }\mu\text{ is the mean and n is the number of terms}\\s \text{ is simply the square root of }s^2\)

d) The population variance is similar to the sample variance except that the divisor is just n instead of n-1.

The probability is: [10C8 + 10C9 + 10C10] / 2^10 =45+10+1 / 2^10 =56/1,024 =5.46875%.

Press "2nd" key first, then use the key labeled "asin", which is the same as sin^-1.

Abby!You finally made a post!

Okay!So is it "fsh"?

cause "i" sounds like "eye"

write an equation of the line given the points (3,25) and (4,31).

(500n + 300m - 100 ) / -100   =

-100 ( -5n - 3n + 1)  / -100  =

-5n - 3n + 1

use the distributive property to rewrite the expression in its equivalent form

(500n + 300m -100) / -100

Let  N be the number of photos

The total cost  C(N)  is  given by :

14.98  + .39N

And when N  = 35, we have

C (35)  = 14.98  +  .39 (35)  =   $ 28.63

The factors of  64  are:   1, 2, 4, 8, 16, 32, 64

The factors of 121 are:   1, 11, 121

So...we can see that their greatest, and only, common factor is 1.

Therefore,   64/121   is in its most reduced form.

There's no need to shout, and btw are you saying that

\(\displaystyle a^{2}+b^{2}=c^{2} , \)

for example, is not an equation ?

4.4721359549995794 - 2√5  \(\stackrel{?}{=}\)  0

2*√5    is the same as    √20      so we can say...

4.4721359549995794 - √20  \(\stackrel{?}{=}\)  0

Add     √20   to both sides.

4.4721359549995794  \(\stackrel{?}{=}\)  √20

Square both sides.

(4.4721359549995794)^2  \(\stackrel{?}{=}\)  20

20.00000000000000006423465417690436  \(\stackrel{?}{=}\)   20

So we can see that it is very close, but not quite completely true.

No not root 5 its root 20

I am unclear why the +30 is between brackets.

but for this kind of equation you have to find x. 

2x=5+30

2x=35

x=35/2=17,5

or the brackets mean times.... i dont know

but for that case

2x=5(30)

2x=5*30

2x=150

x=150/2=75

use the divide sign / 

example

1/2

If you have a longer equation, put the fraction between brackets ()

example

(1/2)

is 1, use the online calculator

"At least eight"   means eight or more....this is a binomial probability  problem....and we have

P ( 8 heads)  =  C(10,8) * .5^8 * .5^2

P(9 heads)  = C(10,9) * .5^9 * .5

P(10 heads)  =  .5^10

So.....the total probability  is

C(10, 8) *.5^8 * .5^2  + C(10,9) * .5^9 * .5  + .5^10  = 7/128   ≈  .0547  ≈  5.47%
