Answer please I’m really struggling with this
katovenus [111]

To write the any polynomial in standard form you must first put it in terms separated only by +,- operators, then you must order terms x^n descendingly according to n. In your case -\frac{1}{5}x^2 will be the first term because it has highest power, followed by -8x^1 and +7x^0.

The standard form of this specific polynomial is:

-\dfrac{1}{5}x^2-2x+7.

Hope this helps.

Enter the numerator that makes the equation true.
Gelneren [198K]

Answer:

1 3/4

Step-by-step explanation:

First write the equation in mixed fraction form as;

1 3/4 + 1 1/3 = 1 _/12 + 1 4/12 ⇒  7/4  + 4/3 = _ + 16/12

7/4  + 4/3 = _ + 16/12

37/12 = _ + 16/12

37/12 - 16/12 = _

= 21/ 12

= 1 9/12

= 1 3/4

Please help for this question. Thank you​

Answer:

A. 8.3

B.18.7

C. 10.4

D. 1.04

Step-by-step explanation:

p(x) = 0.03x² + 0.56x + 6.35

A. Determination of p(3)

p(x) = 0.03x² + 0.56x + 6.35

x = 3

p(3) = 0.03(3)² + 0.56(3) + 6.35

p(3) = 0.03(9) + 1.68 + 6.35

p(3) = 0.27 + 1.68 + 6.35

p(3) = 8.3

B. Determination of p(13)

p(x) = 0.03x² + 0.56x + 6.35

x = 13

p(13) = 0.03(13)² + 0.56(13) + 6.35

p(13) = 0.03(169) + 7.28 + 6.35

p(13) = 5.07 + 7.28 + 6.35

p(13) = 18.7

C. Determination of p(13) – p(3)

From A and B above,

p(13) = 18.7

p(3) = 8.3

p(13) – p(3) = 18.7 – 8.3

p(13) – p(3) = 10.4

D. Determination of p(13) – p(3) / 13 – 3

From C above,

p(13) – p(3) = 10.4

p(13) – p(3) / 13 – 3 = 10.4/ 13 – 3

= 10.4 / 10

= 1.04

Assume that 11 people, including the husband and wife pair, apply for 5 sales positions. People are hired at random. (1) what is
Andrew [12]

The probability that both the husband and wife are hired is \frac{2}{11}

<u><em>Explanation</em></u>

Total number of people = 11 and total number of sales positions = 5

So, the total possible number of ways for selecting 5 people from 11 people will be: ^1^1C_{5}

Now if both the husband and wife are hired, then it means <u>the remaining (5-2)= 3 positions are filled from the remaining (11 -2) = 9 people</u>.

So, the possible number of ways for selecting 3 people from 9 people will be: ^9C_{3}

Thus, the probability = \frac{^9C_{3}}{^1^1C_{5}}=\frac{84}{462}=\frac{2}{11}
