<span>Simplifying 24x + 2y = 48.  Solving 24x + 2y = 48.
  Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right.
 Add '-2y' to each side of the equation.
 24x + 2y + -2y = 48 + -2y.
  Combine like terms: 2y + -2y = 0 24x + 0 = 48 + -2y 24x = 48 + -2y.
  Divide each side by '24'.
x = 2 + -0.08333333333y Simplifying x = 2 + -0.08333333333y</span>

Isolate x.
24x = 48 - 2y

Divide by 24.
x = 2 - y/12

Based on historical data, your manager believes that 40% of the company's orders come from first-time customers. A random sample
Vedmedyk [2.9K]

Answer:

P(0.26 \leq p \leq 0.43)=0.7204-0.0032=0.7172

Step-by-step explanation:

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".  

The population proportion have the following distribution

p \sim N(p=0.4,\sqrt{\frac{p(1-p)}{n}}=\sqrt{\frac{0.4(1-0.4)}{91}}=0.0514)

And we can solve the problem using the z score on this case given by:

z=\frac{p_o -p}{\sqrt{\frac{p(1-p)}{n}}}

We are interested on this probability:

P(0.26 \leq p \leq 0.43)

And we can use the z score formula, and we got this:

P(\frac{0.26 -0.4}{\sqrt{\frac{0.4(1-0.4)}{91}}} \leq Z \leq \frac{0.43 -0.4}{\sqrt{\frac{0.4(1-0.4)}{91}}})

P(-2.726 \leq Z \leq 0.584)

And we can find this probability like this:

P(-2.726 \leq Z \leq 0.584)=P(Z
