Rolling a die. What is the sample space of the experiment? What is the probability of getting a 1 or a 2?
Anvisha [2.4K]

A die has 6 sides, so rolling a 1 out of all six would be 1/6 which equals a 0.16% chance and same goes for a 2/6.

A path 5m wide is to be built along the border and inside a square garden of side 90m. Find the cost of cementing the path at th
gizmo_the_mogwai [7]

Answer:

Total cost of cementing the path = Rs. 17,000.

Step-by-step explanation:

Let the square garden be ABCD

Let the region inside the garden (ABCD) be WXYZ.

<u>Given the following data;</u>

Length of sides of ABCD = 90m

Width of path = 5m

Cost = Rs. 10 per m²

Area of ABCD = 90 * 90

Area of ABCD = 8100m²

<em>To find the area of WXYZ;</em>

WX = WZ = 90 - (5 + 5)

WX = WZ = 90 - 10

WX = WZ = 80m

Area of WXYZ = WX * WZ

Substituting into the equation, we have;

Area of WXYZ = 80 * 80

Area of WXYZ = 6400 m²

Area of path = Area of ABCD - Area of WXYZ

Area of path = 8100 - 6400

Area of path = 1700 m²

Total cost of cementing the path = Area of path * cost

Total cost of cementing the path = 1700 * 10

<em>Total cost of cementing the path = Rs. 17,000</em>

-7y > 161

7y < -161

y < -23

7y > -161

y > -23

So, your answer is: -7y > 161 is equal to y < -23, and 7y > -161 is equal to y>-23.
