Answer:

Step-by-step explanation:

Given that a college student concluded "38% of adults in the United States regularly visit a doctor"

For this,  student  questioned 520 randomly selected members of her college

The problem here is

when she is concluding about the adults as a whole in the world, taking into account the total population of adults, 520 is not a proportional size representing the entire population

Also she selected only members of her college.  This may give a biased opinion.  

To get correct idea, she must survey a large sample size from all over the countries and come to conclusion

Which equivalent four-term polynomial can be created using the X method? x2 8x 8x 48 x2 – 12x – 4x 48 x2 12x 4x 48 x2 – 8x – 8x
Lerok [7]

Polynomial are expressions. The equivalent four-term polynomial of x²+16x+48 is x²+12x+4x+48.

<h3>What are polynomial?</h3>

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

In order to find the equivalent four-term polynomial of the given quadratic equation, we will break constant b(16) into two parts such that the sum of the parts is 16, while their product is equal to the product of the constant a(1) and c(48).

Therefore, the solution of the polynomial is,

x^2+ 16x+48\\\\ = x^2 + 12x+4x+48

Hence, the equivalent four-term polynomial of x²+16x+48 is x²+12x+4x+48.

V=hb

h= \frac V b

h = \dfrac{ x^3 - 3x^2 + 5x - 3}{x^2 -2}

Expressing that as a quotient and remainder,

h =x - 3 = \dfrac{ 7 x - 9} { x^2 - 2}

First choice.

Roberto watched 5 more hours of tv than Jamie last week. Together, they watched a total of 23 hours of tv last week. How many ho
Veronika [31]

Answer: 14 hours

Step-by-step explanation:

Let the number of hours of TV that Jamie watched be represented by x.

Since Roberto watched 5 more hours of tv than Jamie last week, therefore the number of hours of TV that Roberto watched will be: x + 5

Together, they watched a total of 23 hours of tv last week. Therefore,

x + (x + 5) = 23

2x + 5 = 23

2x = 23 - 5

2x = 18

x = 18/2

x = 9

Jamie watched 9 hours of TV

Therefore, Roberto watched x+ 5 = 9 + 5 = 14 hours
