How many percent is 10 3/20?
Liula [17]
3/20 is the same as 15/100 or 15%
so 10×3/20 would be the same as 10×15% or 150%
Is that what you were asking?

The data below represent the ages of people working at a store.
Slav-nsk [51]

Answer:

The first step is sort the values on increasing order and we got:

18, 18, 19, 19, 19, 20, 22, 23. 25,  26, 31

And in order to find the first quartile we can separate the first 5 lowest values from the largest 5 values. And for this case we focus on these values:

18, 18, 19, 19, 19

And if we find the median of the last 5 values we can find the first quartile and we got:

Q_1 = 19

The best answer would be:

19

Step-by-step explanation:

For this problem we have the following dataset:

18, 26, 19, 25, 19, 23, 31, 22, 19, 18, 20

The first step is sort the values on increasing order and we got:

18, 18, 19, 19, 19, 20, 22, 23. 25,  26, 31

And in order to find the first quartile we can separate the first 5 lowest values from the largest 5 values. And for this case we focus on these values:

18, 18, 19, 19, 19

And if we find the median of the last 5 values we can find the first quartile and we got:

Q_1 = 19

The best answer would be:

19

37-(-3)squared+30\(-3)x2
vampirchik [111]
Simplify: 
37 - (-3)^2  + 30/(-3)x^2
= 37 +  - 9 +  - 10x^2

Combine like terms:
= 37 +  - 9 +  - 10x^2
= ( - 10x^2) + (37 +   - 90
= - 10X^2 + 28
Answer: - 10x^2  +  28



To Factor: 
37 - (- 3)^2 + 30/- 3x^2

- 10x^2 + 28
- 2(5x^2 - 14)

Answer:  - 2(5x^2 - 14)




I simplify, and factor, because, you didn't really specify what you wanted help on with this equation. - Thanks -





Hope that helps!!!!

What is the factorization of the expression below?
olchik [2.2K]

Answer: D. (x-6)(x-6)

Step-by-step explanation:

We have the following trinomial, which is also known as perfect square trinomial, because the first and the third term are squares:

x^{2}-12x+36  (1)

First term:x^{2}  

Third term:36=6^{2}  

If we factorize this expression we have:

(x-6)(x-6)=x^{2}-6x-6x+36=x^{2}-12x+36

As we can see, the trinomial (1) has two factors:

(x-6) and (x-6)

Therefore, the correct option is D.
