The area of the given triangle is: 480 m².

<h3>What is the Area of a Triangle?</h3>

Area = 1/2(base × height)

Given:

Base = 64 m

Height = 15 m

Plug in the values into the area formula for triangle:

Area = 1/2(64 × 15)

Area = 1/2(960)

Area = 480 m²

Thus, the area of the given triangle is: 480 m².

Please help me compute standard deviation! Here is the problem, as written.

aleksandr82 [10.1K]

Answer:

The standard deviation for the income of super shoppers is 76.12.

Step-by-step explanation:

The formula to compute the standard deviation for the grouped data probability distribution is:

$\sigma=\sqrt{\sum [(x-\mu)^{2}\cdot P(x)]}$

Here,

<em>x</em> = midpoints

$\mu=\sum x\cdot P(x)$

Consider the Excel table attached below.

The mean is:

$\mu=\sum x\cdot P(x)=32.3$

Compute the standard deviation as follows:

$\sigma=\sqrt{\sum [(x-\mu)^{2}\cdot P(x)]}$

$=\sqrt{259.71}\\\\=76.1155204\\\\\approx 76.12$

Thus, the standard deviation for the income of super shoppers is 76.12.
