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.

B. 15x^2 + 14x + 8
C. 15x^2- 14x-8
D. 15x^2+ 14X-8
Answer:
15x^2 + 14x - 8

(3x + 4) (5x - 2)
1. First: 15x^2
2. Outside: -6x
3. Inside: 20x
4. Last: -8
5. Put Together: 15x^2 - 6x + 20x - 8
6. Simplify: 15x^2 + 14x - 8
A recip says use 3 cups is flour to make 48 cookies what is the contact of proportionality that relays the number of cookies made y, to the number of cups of used, X
Answer:
16
Step-by-step explanation:
y = k * x
Where,
y = number of cookies made = 48
x = number of cups of used = 3
k = constant of proportionality
y = k * x
48 = k * 3
48 = 3k
k = 48/3
k = 16
Therefore,
The constant of proportionality = 16

A newborn baby weighs 3.136 times 10 Superscript 3 units. Which unit of measure was used?
Answer:
grams
Step-by-step explanation:
3.136 x 10³ = 3,136
3136 grams is approximately 7 pounds
there are about 28.3 grams in 1 ounce which means
28.3(16) or 452.8 grams per pound
3136 / 453 ≈ 7

Volume of Composite Figures
Answer:
612 pi m^3
Step-by-step explanation:
Volume of the cylinder = 576 pi m^3
volume of the cone = (radius^2 x pi x height)/3 = (6^2 x pi x 3)/3 = 36 pi m^3
total volume = 576 pi + 36 pi = 612 pi m^3

Solve the given proportion 3/4 6/x x=?
Answer:
X=8
Step-by-step explanation:
3×X =6×4
3X=24
X= 24÷3
X= 8
The equivalent value of the proportion is ( 3/4 ) = ( 6/8 ) and x = 8
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
( 3/4 ) = ( 6/x )
Multiply by x on both sides , we get
( 3/4 )x = 6
Divide by 3 on both sides , we get
( 1/4 )x = 2
Multiply by 4 on both sides , we get
x = 8
Hence , the proportion is ( 3/4 ) = ( 6/8 )
