Answer:

Step-by-step explanation:

3. slope of CB = rise/run = 5/12      BF = 5    CF = 12

BF ⊥ DF

DB (seg of two farthest points) = √BF²+DF² = √5²+32² = √1049 = 32.4

4. f(x) = 2x² - 5x -3      vertex : A (h,k)  for f(x) = ax² + bx +c

h = - b/2a = - (-5 / 4) = 5/4

f = f(h) = 2*(5/4)² - 5*(5/4) - 3 =25/8 - 25/4 -3 = -49/8

A (5/4 , - 49/8) i.e. (1.25 , - 6.13)

negative root:   2x² - 5x -3 = (2x+1) (x- 3)      x = - 1/2      y = 0

B (- 1/2 , 0)

x coordinate of AB: 1/2 (1.25 + -0.5) = 0.375

Answer:

Step-by-step explanation:

Complete Question:

Chapter 6, Section 1-D, Exercise 009 Is a Normal Distribution Appropriate? In each case below, is the sample size large enough so that the sample proportions follow a normal distribution?

a) n=600 p=0.2

b) n=20, p=0.4

if np=10 and npq=10 then  the data follows normal distribution

a) np= 120,

q= 1-0.2= 0.8

npq= 600 ×0.2×0.4 = 48

Normal distribution is appropriate and sample size is large enough

b) np= 8

q= 1-0.4= 0.6

npq= 20 × 0.4×0.6= 4.8

sample size is not large enough so normal distribution is not appropriate.

Given that point A is the midpoint of line segment ED, where E( -1,9) and A(4,5), what is the location of point D?
yuradex [85]

Answer:

  D(9, 1)

Step-by-step explanation:

A being the midpoint means its coordinates satisfy ...

  A = (E + D)/2

Solving for D, we find ...

  D = 2A -E

  = 2(4, 5) -(-1, 9) = (2·4 +1, 2·5 -9)

  D = (9, 1)

sineoko [7]

Answer:

\frac{sin (c)}{AB}=\frac{sin(A)}{26}

sin(A)=\frac{26\times sin(13)}{6} =0.97

A=sin^{-1}(0.97)=\boxed{77^o}

MrRissso [65]

The profit of  5103.5 by making a prescription for 6 tablets.

<h3>What is percentage?</h3>

Percentage, a relative value indicating hundredth parts of any quantity.

The drug Viagra comes in a quantity of 30 tablets with an AWP of $900.

The insurer is willing to pay the AWP less 5% plus a $2.50

900/TAB = X 30 TABS  =$27000

27000 * (0.05)= $1350

27000-1350.00

=$25650 + $2.50

=25652.5 for 30 tablets

For 6 tablets,

= (25652.5 / 30)*6

= 5103.5
