in this kind of exercises you need to work in 3 steps:

1. split your figure into shapes you know

2. calculate the area of those separate shapes

3. add the areas

1. (see picture)

2. shape 1 (triangle)

A= 8m×3m

A= 24m²

2. shape 2 (rectangle)

A= 8m×4m

A= 32m²

3.

total A= A1+ A2

A= 24m²+32m²

A= 56m²

Describe the slope of the line<br><br> Find the slope.<br><br> m =

spin [16.1K]

Answer:

m = -3/5

Step-by-step explanation:

Since the line is going downwards towards the right, it is a negative slope.

We can use the points to solve for the slope.

m = -2 - 1 / 2 - (-3)

m = -2 - 1 / 2 + 3

m = -3/5

Therefore, the slope is -3/5.

3. The following are the scores you shot in five rounds of golf: 70,80,75,75,80. The variance is: A. 3.74 C. 14 B. 196 D. 70

Paladinen [302]

Answer:

Option C.

Step-by-step explanation:

For a given set of N elements:

{x₁, x₂, ..., xₙ}

The mean is given by:

$M = \frac{x_1 + x_2 + ... + x_n}{N}$

And the variance is given by:

$v = \frac{(x_1 - M)^2 + (x_2 - M)^2 + ... + (x_n - M)^2}{N}$

Then for our set:

{70, 80 ,75, 75, 80}

We have 5 elements, then N = 5

The first thing we need to find is the mean.

$M = \frac{70 + 80 + 75 + 75 + 80}{5} = 76$

Then the variance will be:

$v = \frac{(70 - 76)^2 + (80 - 76)^2 + (75 - 76)^2 + (75 - 76)^2 + (80 - 76)^2}{5} = 14$

The correct option is C, 14.
