Answer:
Convenience sampling.
Step-by-step explanation:
Convenience sampling can be understood as a type of sampling that occurs when there is high availability of the population to be investigated.
This method incurs several criticisms because it is not a sampling method that reflects the reality of a population, but convenience sampling can be advantageous due to the speed with which the data are collected and the research initiated, thus being a method recommended for pilot tests.

james lives 4/5 miles from the libary he has already walked 3/4 of the way. How far had james walked
Answer:
600M
Step-by-step explanation:
Convert miles to meters. Then convert the fractions. 1000M divided by 5 = 200. Now times by the numerator of the fraction, which is 4. This gives you 800. Now, 3/4 of 800 = 600. as you divide by the denominator, and times by the numerator. The answer is 600M, or 0.6 Miles.
What is the standard deviation for the data given:
{12, 13, 29, 18, 61, 35, 21}
Answer:
15.866
Step-by-step explanation:
you would first find the mean of the data set by adding all the numbers together and dividing by the number of data points given (7 in this case).
12+13+29+18+61+35+21 = 189189/7 = 27you would then use the mean to solve for the standard deviation by using the equation, σ=√Σ(x-μ)²/N.
first, subtract the mean from all the data points
12-27=-15, 13-27=-14, 29-27=2, 18-27=-9, 61-27=34, 35-27=8, 21-27=-6then, square each calculated value from above
-15²=225, -14²=196, 2²=4, 9²=81, 34²=1156, 8²=64, 6²=36then, add the squared values together
225+196+4+81+1156+64+36 = 1762you would then divide 1762 by 7 (number of data values given orginally)
1762/7 = 251.714finally, take the square root of 251.714 to find the standard deviation
[tex]\sqrt{251.714} = 15.866[/tex]Raja drove from A to B at an average speed of 50mph
The distance between A to B is 10 Miles
Raja took 30 minutes to drive from A to C
He drove from A to C at an average speed of 62mph
Work out Raja’s average speed as he drove from B to C
Answer:
44.7
Step-by-step explanation:
Speed = distance / time
speed from distance a to b = 50 = 10 / time
time = 10/50 = 12 minutes
Speed from a to c = 62 = distance / 30 minutes
distance = 62 x 0.5 = 31 m
diatance from b to c = 31 - 10 = 21
time = 30 - 12 = 28 minutes
speed = 21 / 28 minutes
31 / 0.47

What is the sum of the measures of the angles of a 25-gon?
4,140º
25º
360º
2,500º
Answer:
4140°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 25 , then
sum = 180° × 23 = 4140°

A.CED.1/A.REI.4 Tonya has a rectangular rug as shown. The rug is 4 feet longer than it is wide. (Part A) Create an expression that can be used to determine the length and the width of the rug. Write your answers in terms of x.
help me
Answer:
Width of the rug = x feet
Length of the rug = (x + 4) feet
Step-by-step explanation:
Let
Width of the rug = x feet
The rug is 4 feet longer than it is wide.
Length of the rug = (x + 4) feet
For instance, to find the area of the rug
Area of a rectangular rug = length × width
= (x + 4) * x
= x² + 4x
Area of a rectangular rug = x² + 4x
To find the perimeter of the rug
Perimeter of the rectangular rug = 2(length + width)
= 2{(x + 4) + x}
= 2(x + 4 + x)
= 2(2x + 4)
= 4x + 8
Perimeter of the rectangular rug = 4x + 8

Calculate the surface area?
Please help
Answer:
0.0846153846 when divided
Answer:
806 in^2
Step-by-step explanation:
we can start by breaking it up into two 11x13 sides and four 13x10 sides.
A=l*h
The first group of just two sides is 13*11 = 143, and for both sides 286 in^2
Then for the second group, 13*10 = 130, and for four sides, 520 in^2
We can add these values together for the total surface area, and we'll get 806 in^2 !
