O A) convenience sample
The sampling method which describes the situation is option D. voluntary response sample.
What are Sampling Methods?Sampling methods are methods used to select a sample using specific methods. This includes various types of probability sampling and non probability sampling methods.
This is included in the non probability sampling methods.
So it is either convenience sample or voluntary response sample.
Convenience sample is the selection of a sample which is convenient for you. That is, the sample which is most accessible is selected by the researcher.
Voluntary response sample is also the one which is most accessible. But the researcher is not selecting the sample. Instead the members of the population can decide whether to took part in the sample.
Here it is customer's wish to complete the survey.
So it is voluntary response sample.
Hence the correct option is D. voluntary response sample.

The difference of complementary angles is 10⁰. Find the measures of the angle.
Answer:
40° and 50°
Step-by-step explanation:
Complementary angles sum to 90°
let x be one angle then x - 10 is the other, their sum is
x + x - 10 = 90
2x - 10 = 90 ( add 10 to both sides )
2x = 100 ( divide both sides by 2 )
x = 50
Then angles are 50° and 50° - 10° = 40°
Answer:
50° and 40°
Step-by-step explanation:
Since complementary angles are 90°, the angles combined have to equal to 90.
50 - 40 = 10
40 + 10 = 50
50 + 40 = 90

Car A went 60km in 5/6hours while car B when 54km in 2/3hours which car was faster? How many times Faster?
Answer:
Car B is 1.125 times faster than Car A.
Step-by-step explanation:
Speed = Distance / Time
Car A speed = Car A distance / Car A time
= 60 / (5/6) = 72km / hr
Car B speed = Car B distance / Car B time
= 54 / (2/3) = 81 km /hr
Car B is 81 / 72 ie = 1.125 times faster than Car A.
help find x pls geometry help plssss
Answer:
x = 28
Step-by-step explanation:
From the figure attached,
In ΔABC and ΔADC,
AB ≅ AD [Given]
BC ≅ CD [Given]
AC ≅ AC [Reflexive property]
ΔABC ≅ ΔADC [SSS property of congruence]
Therefore, ∠ABC ≅ ∠ADC [CPCTC]
(4x + 13)° = (5x - 15)°
15 + 13 = 5x - 4x
x = 28

Answer:
7d=30
d=18.5714
Step-by-step explanation:
Answer:
d=20
Step-by-step explanation:
4d & 3d are like terms because they both have a variable.
20 & 5 are alike because they both don't have a variable.
First you would add 4d and 3d together, and you will get 7d.
4d+20+3d-5=155
7d+20-5=155
Next you can subtract 5 from 20.
7d+15=155
Then you subtract 15 from both sides of the equation.
7d=140
Then you divide by 7 on both sides.
And you are left with d=20

Jackson said that he made a triangle that had side lengths of 6 units, 6 units and 14 units. Is this a possible triangle?
Answer:
The triangle will not be possible.
this is because two side lengths can't expand 14 units.
in order for the triangle to work, the sum of the two short side lengths must be greater than the longer side.
however, 6+6 does not equal 14 it equals 12 this means that the triangle is not possible
