A spinner has regions numbered 1 through 21. what is the probability that the spinner will stop on an even number or a multiple
2 answers:
Answer:
Step-by-step explanation:
Given : The total number of regions in the spinner = 21
The outcomes for even number =2,4,6,8,10,12,14,16,18,20
The outcomes for multiple of 3 = 3,6,9,12,15,18,21
The number of outcomes of getting an even number or a multiple of 3 = 14
Then, the probability that the spinner will stop on an even number or a multiple of 3 will be :-
Hence, the probability that the spinner will stop on an even number or a multiple of 3 is

Answer:
The required equation is: y=-3
Option D is correct.
Step-by-step explanation:
We need to write equation of line that is perpendicular to y = 5 and passes through (-4,-3).
The equation of line in slope-intercept form is expressed as:
where m is slope and b is y-intercept.
Finding Slope:
Comparing with the given equation y=5, the slope m =0
The slope of required line will be opposite reciprocal of 0 as both lines are perpendicular. so it will be m=0
Finding y-intercept
The y-intercept can be found using slope m=0 and point (-4,-3)
So, y-intercept b is b=-3
The equation of required line having slope m=0 and y-intercept b=-3 is
So, required equation is: y=-3
Option D is correct.
keeping in mind that in a rhombus all sides are equal, Check the picture below.
