n their last basketball game, Becky scored twice as many points as Min. Together, they scored 42 points. How many points did Bec
Makovka662 [10]

Becky =B

Min =M

B =2M and B + M = 42.

(2M) + M= 3M = 42 and so M=42/3=14.

B = 2M so it's 14*2=28


Becky scored 28 points.

Factor completely 9x3 36x2 − x − 4. (3x 4)(3x − 4)(x 1) (3x 1)(3x − 1)(x 4) (9x2 − 1)(x 4) (3x 1)(3x − 1)(x − 4).
Arlecino [84]

The factor of the provided polynomial after the factorization process are similar to option B, which is

(x+4)(3x+1)(3x-1)

<h3>How to find the factor of polynomial?</h3>

The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.

Find these factors by taking out the common factors.

The given polynomial equation in the problem is,

9x^3 +36x^2 - x - 4

The above equation has the unknown variable x and the highest power of this unknown variable is 3.

Take out the highest common factor 9x², which can divide each term of the first two terms of equation (9x³, 36x²). Thus,

9x^2(x +4) - x - 4

Take out the highest common factor -1 from the second two terms as,

9x^2(x +4) -1( x + 4)

Now take out the common group (x+4) as,

(x +4) ( 9x^2 -1)

The second group can be rewritten using the difference of square formula as,

(x +4) ( (3x)^2 -1^2)\\(x+4)(3x+1)(3x-1)

Thus, the factor of the provided polynomial after the factorization process are similar to option B, which is

(x+4)(3x+1)(3x-1)

The line plot below shows the number of kilometers Clara ran each day for 14 days. Find the average. Hint: Each X on the line pl
vitfil [10]

Answer:

Average=7

Step-by-step explanation:

From the line plot

  • 4 has three Xs above it
  • 5 has four Xs above it
  • 6 has four Xs above it
  • 11 has one X above it
  • 15 has one X above it
  • 16 has one X above it

Therefore, the values are:

4,4,4,5,5,5,5,6,6,6,6,11,15,16

Average=\dfrac{(4*3)+(5*4)+(6*4)+11+15+16}{14} \\=\dfrac{12+20+24+11+15+16}{14}\\=\dfrac{98}{14}\\

Average=7

Determine whether each sample may be biased. Explain.
34kurt

Answer:

5: yes he could easily chose bigger looking families to get the result he wants

6: no he has isn't choosing people and has no idea the answers presumibly

7: no it's not something that they could choose or know what is going to happen, therefore or can't be biased.

I'm not sure if I did it right but I think that's what it's asking sorry if I'm wrong
