The weights of the fish in a certain lake are normally distributed with a mean of 11 lb and a standard deviation of 6. if 4 fish

Alexus [3.1K]

Since the sample standard deviation is now known, we use the z-score test. The formula is given as:

z= (X – μ) / (s / sqrt(n))

Where,

X = sample mean = 8.6 lb to 14.6 lb

μ = population mean = 11 lb

s = population standard deviation = 6

n = sample size = 4

1st: Calculating for z when x = 8.6 lb

z = (8.6 – 11) / (6 / sqrt4)

z = - 0.8

Using the standard distribution table for z:

Probability (x = 8.6 lb) = 0.2119

2nd: Calculating for z when x = 14.6 lb

z = (14.6 – 11) / (6 / sqrt4)

z = 1.2

Using the standard distribution table for z:

Probability (x = 14.6 lb) = 0.8849

Therefore the probability that the mean weight will be between 8.6 and 14.6 lb:

Probability (8.6 ≤ x ≤ 14.6 ) = 0.8849 - 0.2119

Probability (8.6 ≤ x <span>≤ 14.6 ) = 0.673 (ANSWER)</span>

Which ordered pair is the best estimate for the solution of the system of equations? y=−2/5x−2y=5x+1

lutik1710 [3]

Option a: $(-0.5,-1.75)$ is the solution to the system of equations.

Explanation:

The equations are $y=-\frac{2}{5} x-2$ and $y=5 x+1$

Equating these two equations, we have,

$-\frac{2}{5} x-2=5 x+1$

Taking LCM and multiplying both sides by 5, we get,

$-2 x-10=25 x+5$

Simplifying , we get,

$\begin{aligned}-10-5 &=25 x+2 \\-15 &=27 x \\-\frac{15}{27} &=x \\-\frac{5}{9} &=x\end{aligned}$

Substituting the value of x in $y=5 x+1$ , we get,

$\begin{aligned}&y=5\left(-\frac{5}{9}\right)+1\\&y=-\frac{25}{9}+1\\&y=-\frac{16}{9}\end{aligned}$

Thus, the solution is $\left(-\frac{5}{9},-\frac{16}{9}\right)$

Changing the solution from fraction to decimal, we get, $(-0.556,-1.778)$

Thus, the solution is $(-0.5,-1.75)$

Hence, option a is the correct answer.

A group of friends is playing a game with the spinner shown. They win or lose money according to the segment the spinner lands o

Otrada [13]

The 8 sectors appear to be equal in size, so equally likely.
The total of the winnings = 2 + 3 + -5 + -2 + 10 + 3 + -5 + -2 = 4
Expected winnings on average = 4 / 8 = $0.50.
