Data were collected on random specimens of Yellowfin tuna from 1991 and 2010. For the sample of 231 specimens of Yellowfin tuna,

Molodets [167]

Answer:

95% confidence interval: (0.325 ,0.383)

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 231

Sample mean = 0.354 ppm

Sample standard deviation = 0.231 ppm

95% confidence interval:

$\bar{x} \pm t_{critical}\displaystyle\frac{s}{\sqrt{n}}$

Putting the values, we get,

$t_{critical}\text{ at degree of freedom 4 and}~\alpha_{0.01} = \pm 1.97$

$0.354 \pm 1.97(\dfrac{0.231}{\sqrt{231}} ) = 0.354 \pm 0.029 = (0.325 ,0.383)$

Complete the perfect square v^2-2v=3

Dmitriy789 [7]

V² - 2v = 3
v² - 2v - 3 = 0
v = -(-2) +/- √((-2²) - 4(1)(-3))
 2(1)
v = 2 +/- √(4 + 12)
 2
v = 2 +/- √16
 2
v = 2 +/- 4
 2
v = 2 + 4 v = 2 - 4
 2 2
v = 6 v = -2
 2 2
v = 3 v = -1

Simplify the following expression -5[(x^3+1)(x+4)]

katrin [286]

Answer:

Step-by-step explanation:

-5[ (x³+1)(x+4) ] = -5[ x³*(x+4) + 1*(x+4) ]

= -5 [ x³*x + x³*4 + 1*x + 1*4 ]

= -5 [ x⁴ + 4x³ + x + 4]

= -5*x⁴ + (-5)*4x³ + (-5)*x + (-5) * 4

= -5x⁴ - 20x³ - 5x - 20
