Answer: Simple Random
Step-by-step explanation:
- A simple random sampling technique is a random sample technique in which a subset of the population is drawn by the researcher . They are chosen in such a way that all the individuals in the population has an equal chance to get chosen .
Given : In a study, the sample is chosen by pulling 50 names from a hat .
Here the probability of each name to get selected is equal.
Thus, this is a simple random sampling method.
Answer:
every 6 rolls
Step-by-step explanation:
Answer:
x > 
Step-by-step explanation:
Given
x - 
> 1
Multiply through by 15 to clear the fractions
10x - 3 > 15 ( add 3 to both sides )
10x > 18 ( divide both sides by 10 )
x > 
, that is
x >
The answer is c
(x-2)(-10x-12)
Answer:
A = 55 degrees
B = 35 degrees
C = 90 degrees
side BA = 4.8 units
side AC = 2.7 units
side BC = 3.9 units
Step-by-step explanation:
Hello!
The things we know:
A = 55 degrees
C = 90 degrees
side BA = 4.8 units
AC = adjacent side
BC = opposite side
AB = hypothenuse
B = 180 - 55 - 90 degrees
B = 35 degrees
Let's find side AC
we can use the cos of theta.
cos(55) = AC/4.8
multiply 4.8 on both sides.
4.8cos(55) = AC
AC = 2.7 units
And now we just have to find BC
to calculate BC we can either use tangent or sin.
I will just use sin
sin(55) = BC/4.8
multiply 4.8 on both sides.
4.8sin(55) = BC
BC = 3.9
And now we know everything about the triangle
Hope I Helped!
