Discussion:

(d+5) ( d-5) = d^2 - 25 so the answer is (d+5) or choice D

Thank you,

Answer:

The correct answer is Option C . d -5

Step-by-step explanation:

Identity: (a + b)(a - b) = a² - b²it is given that,

it is given that,

(d - 5)(?) = d² - 25

LHS = (d - 5)(?)

RHS = d² - 25

we can compare this with the identity.

here, a = d and b = 5

therefore we can write and start with RHS

RHS = d² - 25 = d² - 5² = (d +5)(d - 5) = LHS

(d +5)(d - 5) = d² - 25

Therefore option C. (d- 5) is the correct answer.

Solving Proportions 19/4 = x/4

fredd [130]

Answer:

x = 19

Step-by-step explanation:

To solve proportions, you first need to cross multiply. $\frac{19}{4}= \frac{x}{4}$ , you would need to multiply each top number by 4. 76 = 4x, which then could easily be simplified down to 19 by just dividing by four.

Suppose you just received a shipment of twelve televisions. Three of the televisions are defective. If two televisions are rando

qwelly [4]

Answer: The probability that both televisions work is 0.5625 .

The probability at least one of the two televisions does not work is 0.4375.

Step-by-step explanation:

Given : Number of televisions received in shipment= 12

Number of defective televisions received in shipment= 3

Then proportion of defective televisions = $\dfrac{3}{12}=0.25$

Using binomial probability formula, the probability of getting success in x trials is given by :-

$P(x)=^nC_xp^x(1-p)^{n-x}$

If two televisions are randomly selected, then the probability that both televisions work will be :-

$P(0)=^2C_0(0.25)^0(0.75)^2=(0.75)^2=0.5625$

The probability at least one of the two televisions does not work will be :-

$P(x\geq1)=1-P(0)=1-0.5625=0.4375$

A class has 14 girls and 12 boys. What is the probability that a girl's name is drawn at random?

Otrada [13]

14 over 26. Because if you want to find out the probability, you need to put the number of girls over the total of students.
Hope this helps!!!:)

How do you determine the degree of a polynomial

yawa3891 [41]

Answer:

The degree of a polynomial refers to the highest degree of its individual terms having non-zero coefficients.

Step-by-step explanation:

The degree of a polynomial refers to the highest degree of its individual terms having non-zero coefficients. For example;

A quadratic polynomial is a polynomial of degree 2. This polynomial takes the general form;

$ax^{2}+bx+c$

where a, b, and c are constants. This is usually referred to as a quadratic polynomial in x since x is the variable. The highest power of x in the polynomial is 2, hence the degree of any quadratic polynomial is 2.

A second example, consider the cubic polynomial;

$ax^{3}+bx^{2}+cx+d$

The degree of this polynomial is 3.
