Answer:

The property the equation illustrates would be the zero property of addition.

Use the polynomial 3x^2−4x^11+4x^4−2x^10−5+^8x^8 to answer the question.

Anit [1.1K]

Answer: 11

<u>Step-by-step explanation:</u>

3x² - 4x¹¹ + 4x⁴ - 2x¹⁰ - 5 + 8x⁸

To find the degree, look for the largest exponent. <em>11</em>

If you put this polynomial in standard form (from largest to smallest exponent), the first term will give you the degree of the polynomial and the leading coefficient.

- 4x¹¹ - 2x¹⁰ + 8x⁸ + 4x⁴ + 3x² - 5

Dr. Hawk works in an allergy clinic, and his patients have the following allergies: 71 are allergic to dairy products, 98 are al

sweet [91]

Answer: a) 65.75% and b) 13.7%

Step-by-step explanation:

Since we have given that

Number of people who are allergic to dairy products = n(A) = 71

Number of people who are allergic to pollen = n(B) = 98

Number of people who are allergic to animal dander = n(C) = 96

Number of people who are allergic to all n(A∩B∩C) = 33

Number of people who are allergic only to pollen = 30

Number of people who are allergic only to dairy product = 10

Number of people who allergic to dairy products and pollen n(A∩B)= 43

Now, we first find a, c, d, e from the Venn Diagram:

Since n(A∩B)= 43

$a+b=43\\\\a+33=43\\\\a=43-33\\\\a=10$

For Diary product,

$10+a+b+c=71\\\\a+b+c=61\\\\10+33+c=61\\\\c=18$

For pollen,

$a+30+b+e=98\\\\10+30+33+e=98\\\\e=98-73=25$

For animal dander,

$c+b+d+e=96\\\\18+33+25+d=96\\\\d=96-76=20$

So, Total allergic persons = 10+18+20+25+30+10+33=146

So, (a) What percent of Dr. Hawk's patients are allergic to animal dander?

Percentage that patients are allergic to animal dander is given by

$\dfrac{96}{146}\times 100=65.75\%$

(b) What percent of Dr. Hawk's patients are allergic only to animal dander?

Percentage that patients are allergic to only animal dander is given by

$\dfrac{20}{146}\times =13.7\%$

Hence, a) 65.75%

b) 13.7%
