How is a greater number a factor of a smaller number?
Eduardwww [97]

Explanation:

It depends on the definition of "factor" that you use.

One dictionary defines "factor" to be ...

  "a number or quantity that when multiplied with another produces a given number or expression"

In that sense, 7 can be a factor of 3, because 7 × (3/7) = 3.

___

Often we use the term "factor" when we mean "integer divisor", or "positive integer divisor". Using this last definition, the only factors of 3 are 1 and 3.

Other times, we use the term "factor" to mean "prime factor." By this definition, the only factor of 3 is 3 itself.

The area of the right triangle shown is 30 ft squared. The segment XY has a length of 5 ft. Find the length of the hypotenuse.
alexgriva [62]

Answer:

Hypotenuse is 13 ft.

Step-by-step explanation:

A=(1/2)bh

30=(1/2)(5)(h)

30=2.5h

h=12  so ZY = 12ft

Then

a^{2} +b^{2} =c^{2} \\5^{2} +12^{2} =c^{2} \\25+144=c^{2} \\169=c^{2}\\13=c

Step-by-step explanation:

-4       1

---   /    ---

9n       15n

Keep, change, flip

- Keep the -4/9n

- Change the division sign to a multiplication sign

-4       15n

---   *    ---

9n       1

Cross simplify.

9n divided by 3 is 3n.

15n divided by 3 is 5n.

ANTONII [103]

Answer:

Hence the degrees of freedom are associated with the critical value is 25.

Step-by-step explanation:

Using two independent samples, two population means are  

compared to determine if a difference exists, the population standard deviation is equal.  

sample size 1 = n_{1}= 15 and sample size 2 = n_{2} = 12  

since, population standard deviations are equal, required degrees of freedom              

= n_{1}  + n_{2} - 2 \\= 15 + 12 - 2\\ = 25
