The sampling method which is least likely to include sampling bias is: A. A random sample of 500 adults in the state.

A sampling bias can be defined as a type of bias in which members of an intended population are selected in such a way that some members have a higher or lower sampling probability than the other members.

This ultimately implies that, a sampling bias occur when members of an intended population are selected incorrectly and as such resulting in a sample that is not representative of the entire population.

In conclusion, a random sample of 500 adults in the state is least likely to include sampling bias.

Answer:B

Step-by-step explanation:

Since both equations are equal to y, we can set -2x-1=(1/2)x+4.

[tex]-4x-2=x+8\\-5x-2=8\\-5x=10\\x=-2\\y=-2(-2)-1=3[/tex]

This is point  B

Here we have some problems about circles, the solutions are:

We know that for a circle of diameter D, the area is given by:

A = pi*(D/2)^2

where pi = 3.14

In the image we can see that the diameter of the circle is 25 yd, replacing that in the area equation we get:

A = 3.14*(25yd/2)^2 = 490.6 yd^2

For the second image, each line creates two 180° angles. So, if we look at the tilted line, we can see that it is divided in two angles, one of 37° and the other that depends of x, so we can write:

180° = 37° + (9x + 8)°

180° - 37° - 8°  = (9x)°

135°/9° = x = 15

So the value of x is 15.

For the last image:

Notice that we have a 90° angle denoted, then the other 3 sections must add up to 270°.

270° = 54° + (2x + 21)° + (5x + 6)°

Now we solve this for x:

270 - 54 - 21 - 6 = 2x + 5x

189 = 7x

189/7 = x = 27

x is equal to 27

Answer:

35 m²

Step-by-step explanation:

Given:

⇒ length of hedge = (1.2 ÷ 2) x 11 = 6.6 m

Given:

⇒ length of pond = 2 x 4 = 8m

Given:

⇒ width of pond = 28 ÷ 8 = 3.5 m

⇒ perimeter of pond = 2 x 8 + 2 x 3.5 = 23 m

Given:

⇒ length of flowerbed = 8 + 2 = 10 m

Given:

⇒ width of flowerbed = [23 - (2 x 10) ] ÷ 2 = 1.5 m

Area of grass = (length of gate x width of pond) + (length of flowerbed x [length of hedge + length of compost heap - width of flowerbed - width of pond])

= (2 x 3.5) + (10 x [6.6 + 1.2 - 1.5 - 3.5])

= 7 + (10 x 2.8)

= 35 m²
