1. A= width*height=h ^2 = (3)^2 = 9 
2. A=width*height 
height is still gonna be h 
Area is given in the problem 
h^2+8h+12=(width)h 
So doing some long division.. 
h√h^2+8h+12 = h+8+12/h 
-(h^2) 
8h+12 
-(8h) 
12 

3. A=width*height=h(h+4)=h^2+4h

In a survey of adults who follow more than one sport, 30% listed football as their favorite sport. You survey 15 adults who foll
maxonik [38]

Answer: 0.5

Step-by-step explanation:

Binomial probability formula :-

P(x)=^nC_x\ p^x(q)^{n-x}, where P(x) is the probability of getting success in x trials , n is the total trials and p is the probability of getting success in each trial.

Given : The probability that the adults follow more than one game = 0.30

Then , q= 1-p = 1-0.30=0.70

The number of adults surveyed : n= 15

Let X be represents the adults who follow more than one sport.

Then , the probability that fewer than 4 of them will say that football is their favorite sport,

P(X\leq4)=P(x=0)+P(x=1)+P(x=2)+P(x=3)+P(x=4)\\\\=^{15}C_{0}\ (0.30)^0(0.70)^{15}+^{15}C_{1}\ (0.30)^1(0.70)^{14}+^{15}C_{2}\ (0.30)^2(0.70)^{13}+^{15}C_{3}\ (0.30)^3(0.70)^{12}+^{15}C_{4}\ (0.30)^4(0.70)^{11}\\\\=(0.30)^0(0.70)^{15}+15(0.30)^1(0.70)^{14}+105(0.30)^2(0.70)^{13}+455(0.30)^3(0.70)^{12}+1365(0.30)^4(0.70)^{11}\\\\=0.515491059227\approx0.5

Hence, the probability rounded to the nearest tenth that fewer than 4 of them will say that football is their favorite sport =0.5

0.125 is how many cups
storchak [24]
Well, you didnt exactly give me enough information to do the problem, but here it goes;
0.125 is a decimal, and as a fraction it converts to 1/8. Therefore, depending on the original unit, it could be 1/8 of a cup.

Let f(x) = -2x + 7 and g(x) = -6x + 3. Find fxg and state its domain.
marissa [1.9K]

Option D: (f\times g)(x)=12 x^{2}-48 x+21; all real numbers.

Explanation:

Given that the functions are f(x)=-2 x+7 and g(x)=-6 x+3

We need to determine the value of (f\times g)(x) and its domain.

<u>The value of </u>(f\times g)(x)<u>:</u>

The value of (f\times g)(x) can be determined by multiplying the two functions.

Thus, we have,

(f\times g)(x)=f(x)\times g(x)

                =(-2x+7)(-6x+3)

                =12x^2-6x-42x+21

(f\times g)(x)=12 x^{2}-48 x+21

Thus, the value of (f\times g)(x) is (f\times g)(x)=12 x^{2}-48 x+21

<u>Domain:</u>

We need to determine the domain of the function (f\times g)(x)

The domain of the function is the set of all independent x - values for which the function is real and well defined.

Thus, the function (f\times g)(x)=12 x^{2}-48 x+21 has no undefined constraints, the function is well defined for all real numbers.

Hence, Option D is the correct answer.
