Answer:

20 -3p -p^2 = p- 1

20 -3p -p = p^2 -1

20 -4p = p^2 -1

20 +1 = p^2 +4p

21 = p^2 +4p

p^2 +4p -21

A survey of athletes at a high school is conducted, and the following facts are discovered: 33% of the athletes are football pla

sergejj [24]

Answer: 0.79 or 79%

Step-by-step explanation:

Given : The probability that the athletes are football players : P(A)=0.33

The probability that the athletes are basketball players: P(B)=0.66

The probability that the athletes play both football and basketball : P(A∩B)=0.20

Now, the probability that the athlete is either a football player or a basketball player is given by :-

$P(A\cup B)=P(A)+P(B)-P(A\cap B)\\\\=0.33+0.66-0.20=0.79$

Hence, the probability that the athlete is either a football player or a basketball player = 0.79

Or we can write it as 79%.

In a circle, a 90-degree sector has area 196 pi in^2. What is the radius of the circle?

o-na [289]

Answer:

The radius of the circle is $28\ in$

Step-by-step explanation:

we know that

In a circle, a 90-degree sector represents a quarter of the circle area.

The area of a quarter circle is equal to

$A=\frac{1}{4}\pi r^{2}$

we have

$A=196\pi\ in^{2}$ ----> area of a quarter circle

so

$196\pi=\frac{1}{4}\pi r^{2}$

Simplify

$r^{2}=196*4$

$r=28\ in$

What is the area of the white border?

Lina20 [59]

Answer:

$A_{white} = 119\ cm^2$

Step-by-step explanation:

<u>Step 1: Determine the area of the black area</u>

$A = l * w$

$A = 8\ cm * 2\ cm$

$A = 16\ cm^2$

<u>Step 2: Determine the area of the entire white and black area</u>

$A = l * w$

$A = 9\ cm * 15\ cm$

$A = 135\ cm^2$

<u>Step 3: Determine the difference to just get the white area</u>

$A_{white} = 135\ cm^2 - 16\ cm^2$

$A_{white} = 119\ cm^2$

Answer: $A_{white} = 119\ cm^2$
