Answer:
x=25 degrees
Step-by-step explanation:
x= 90 degrees - given(65 degrees)
x=90-65
x=25 degrees.
The angles add up to 90 degrees.
Answer:
<h3>1/4</h3>
Step-by-step explanation:
Given
amount of salamanders, = 5
amount of crayfish = 3
amount of minnows = 12
Total fish = Total outcome = 5+3+12
Total outcome = 20
Since we are looking for the probability of selecting salamanders, our expected outcome will be 5.
Probability = expected outcome/total outcome
Pr( salamanders,) = 5/20
Pr( salamanders) = 1/4
Hence the probability of selecting salamanders, is 1/4
Radius is 6 and centre is (-4,2)
A graphing calculator can be helpful for these.
A) Since neither inequality includes the "or equal to" case, the boundary line for the solution set is a dashed line. For the first inequality, the shading is above the line; for the second, the shading is below the line. The solution set is points to the right of perpendicular lines with slope -2 and +1/2 through point (2, -1).
B) The point -2, 3 satisfies, neither inequality.
