Answer: Formula= x^2 - 2x - 8

Roots=(-2 , 0) (4 , 0)

Step-by-step explanation:

1.) find the equation (the formula is Ax^2 + Bx + C, so plug it in)

2.)Plug it into your calculator's Y= X^2 - 2X - 8 (if you have one)

3.)Press 2nd, Calc, 2

4.)Go to the X Intersect , it will say Left Bound at the bottom left corner

5.)Press the left arrow about 3 or 4 times, hit enter

6.) It will now say Right Bound in the same corner go back to the X intersect, now press the right arrow 3 or 4 times

What is the approximate area of the circle shown below?

Lynna [10]

Answer:

A. 2827 square cm

Step-by-step explanation:

Diameter of circle = 60 cm

Therefore, radius = 60/2 = 30 cm

$Area \: of \: circle \\ = \pi {r}^{2} \\ = 3.14159265\times {30}^{2} \\ = 3.14159265 \times 900 \\ = 2,827.43339 \: {cm}^{2} \\ = 2827 \: {cm}^{2}$

A certain tennis player makes a successful first serve 6969% of the time. Suppose the tennis player serves 9090 times in a matc

Wewaii [24]

Answer:

a) 4.387

b) Yes, because np & npq are greater than 10.

c) = 0.017

Step-by-step explanation:

Give data:

p = 0.69

n = 90

a) a

E(X) = np = 62.1

$SD(X) = \sqrt{(np(1-p))}$

$=\sqrt{90\times 0.69(1- 0.69)}$

= 4.387

b)

np = 62.1

q = 1 - p = 1 - 0.69 = 0.31

npq = 19.251

Yes, because np & npq are greater than 10.

c.

$P(X \geq 72 ) = P(X > 71.5)$ [continuity correction]

$= P(Z> \frac{((71.5-62.1)}{ 4.387})$

= P(Z> 2.14 )

= 1 - P(Z<2.14)

= 1 - 0.983 (using table)

= 0.017
