<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

Their vacation savings account currently has a balance of $2,764.

The family would like to have at least $5,000.

<h3>To find </h3>

The amount of money the family still needs to save.

<h3>How to find the amount of money the family still needs to save?</h3>

Forming the equation, we get

Let x be the amount needed to save. then

x + 2764 ≥ 5000

On simplifying, we get

x + 2764 ≥ 5000

x ≥ 5000 - 2764

x ≥ 2236

Thus, the amount of money the family still needs to save is $2236.

<h2>Answer with explanation:</h2>

Given : Sample size : n = 36

Significance level for 90% confidence : $\alpha: 1-0.9=0.1$

Sample mean : $\overline{x}=0.60$

Standard deviation : $\sigma=0.08$

By using standard normal table for t-values,

Critical t-value : $t_{(n-1, \alpha/2)}=t_{(35,\ 0.05)}=1.690$

Thus, the correct value of t to construct a 90% confidence interval for the true mean percentage of cacao : $t_{(35,\ 0.05)}=1.690$

Confidence interval for population mean :

$\overline{x}\pm t_{(n-1, \alpha/2)}\dfrac{\sigma}{\sqrt{n}}\\\\=0.60\pm(1.69)\dfrac{0.08}{\sqrt{36}}\\\\=0.60\pm0.0225333333333\\\\\approx0.60\pm0.023\\\\=(0.60-0.023,\ 0.60+0.023)=(0.577,\ 0.623)$

Hence, A is the correct answer .
