The answer would be b- 3 out of 5.

Explanation- Since 8 of the beans are blue, 12 of them are not. Since 60% of the beans are not blue, that can be changed to the fraction of 6/10 which can be reduced to 3/5

Consider the function: f(x) = x2 - 6x + 9. determine the value of f(1/2)

Lena [83]

Step-by-step explanation:

f(x) = x² − 6x + 9

f(½) = (½)² − 6(½) + 9

f(½) = ¼ − 3 + 9

f(½) = 6¼

The value is 6¼, or as an improper fraction, 25/4.

10. Suppose you are a salesperson for the Acme Dynamite Company. Each month you earn $400 plus one sixth of your sales.

Liula [17]

ANS

$15600 worth of explosives.

$3000 = $400x

$3000 - 400 ( 1/6x )

$\\ = ( \frac{1}{6} x)$

= $2600

$\\ = ( \frac{1}{6} x)$

= $

$\\ \frac{2600}{ \frac{1}{6} } = x$

$x = 15600$

Answer:

d) 6.750

The chi - square value = 6.750

Step-by-step explanation:

Given data

Starting Position 1 2 3 4 5 6

Number of Wins (O) 33 44 32 36 45 50

Step(i) :-

mean = $\frac{33+44+32+36+45+50}{6} = \frac{240}{6} =40$

Expected frequency = 40

Number of Wins (O) : 33 44 32 36 45 50

Expected frequency(E) : 40 40 40 40 40 40

(O - E ) : -7 4 -8 -4 5 10

(O-E)² : 49 16 64 16 25 100

$\frac{(O-E)^2}{E}$ : 1.225 0.4 1.6 0.4 0.625 2.5

Step(ii):-

The χ² test

χ² = ∑ $\frac{(O-E)^2}{E}$

χ² = 1.225 + 0.4 + 1.6 + 0.4 +0.625 +2.5 = 6.75

The chi - square value = 6.750

Final answer:-

The chi - square value = 6.750
