12000+875=12875 the total he paid
12000*x/100*4=12875
480x=12875
x=12875/480
x=26,82 %
The answer is the first one, she should expect the slope to be negative because the line tilts down moving from left to right
Acute is less then 90 degrees, right is 90 degrees, and obtuse is more then 90 degrees.
Answer:
c) gives each member of the population a known chance to be selected
Step-by-step explanation:
A sample is said to be a probability sample when each and every unit of the population would have the known chance or the probability i.e. more than zero when selected in the sample
So according to the given options, it is the sample where each member have the known chance to be selected
Therefore the option c is correct
Answer:
Step-by-step explanation:
None of them
A has (5, 13) and (5,17) That's 2 y values for the same x. You can't have that. A fails the vertical line test.
B has two y values for x = - 3. The two values are (-3,-1) and (-3,1). Both values eliminate B as an answer.
C fails because -1 has 2 y values (-4,52) and (-4,?) We can't see the bottom, but it is another value. There is an x value we cannot see that has 45 as an answer along with -7 for x. That's fine.
If there is a D answer, you almost have to choose it. There isn't much choice.
