Answer:

bias

Step-by-step explanation:

Samples are randomized to ensure that the people polled are representative of the entire population.  If a sample is not representative of the population, it is said to be biased.  Randomization helps to prevent bias.

What is 1 divided by 5^-2? Please give clear explanation. thanks.
Pani-rosa [81]
1 / 5^-2

First, let's work out the denominator.
5^ -2 = 1/25. When an exponent is negative, it means to put a 1 over the product. Like we did earlier.

Now we have 1 / (1/25). 

1 / (1/25)
Divide 1 by 25.
1 / 0.04
Divide 1 by 0.04
25

The answer is 25!

Now if you make this answer as the Brainliest I will appreciate it very much. And for a limited time answer, and no scam or joke,  you will receive your very own flying space ship! No scam at all! Try it. Just press the mark as Brainliest and watch your spaceship land in your backyard! But seriously I will appreciate it if you mark this answer as the Brainliest.

An airplane takes off from the ground and reaches a height of 500 feet after flying 2 miles. given the formula h = d tan θ, wher
zloy xaker [14]

Height covered by the plane=h= 500 feet

Distance covered by the plane along the ground=d= 2 mile

Now, convert the mile into feet,

1 mile = 5280 feet

2 mile = 10560 feet

Now, use the formula

h= d tanθ

tanθ= h/d

tanθ= 500/10560

tanθ= 25/528

Take the tan⁻¹ on both side,

θ= tan⁻¹(25/528)

θ =2.71°
