47% of those who received a certificate were men
It is given that in an Italian class, 65 percent of the students were women. At the end of the class, 52 percent of the men and 44 percent of the women received a certificate.
Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty.

Answer:
Perpendicular bisector
Step-by-step explanation:
Have a great day!!
Answer:
B. The first equation in B is the sum of the equations in A, while the other is obtained
by multiplying the first equation in A by 2.
Step-by-step explanation:
If we add the first two equations that shown in A so
6x + 8y + 2x - 5y = -10 + 12
8x + 3y = 2
Now the first equation in A would be multiplied by 2
So
2(6x + 8y = -10)
12x + 16u = -20
Therefore the correct option is B.
Answer:
The total number of elements in the sample space of the experiment for 3 stages = 64 (C)
Step-by-step explanation:
The number of equally likely sample outcomes of the single stage experiment = 4
For n number of stages, the total number of elements in the sample space = (outcome of a single stage)^n
This is = 4^n
To determine the total number of elements in the sample space if the experiment has 3 stages, we would multiply the outcome of one experiment three times.
Where n = 3
The total number of elements in the sample space of the experiment for 3 stages = 4³
= 4×4×4 = 64
The total number of elements in the sample space of the experiment for 3 stages = 64 (C)
