No
Is the following relation a function ? Yes No - 1

Answers

Answer 1
Answer:

Answer:

No

Step-by-step explanation:

For a relation to be a function, each value of x must map to exactly one unique value of y

Here x = 4 and x = 0 both map to y = 3

Thus the relation is not a function

When the point (-3,2) is reflected across the y-axis, what are the coordinates of the resulting point?

Answers

A reflection across the Y-axis means that the Coordinate's X-value switches signs and the Y-value stays the same.  So in the case of (-3,2)
being reflected across the y-axis that means that -3 flips its sign and becomes a normal 3 and the 2 stays the same.  Therefore the new coordinate is (3,2)

If m is the midpoint of xy find the coordinates of x if m -3,-1 and y -8,6

Answers

Answer:

To find the coordinates of x, we can use the midpoint formula, which says that the midpoint of a line segment is the average of the x-coordinates and the y-coordinates of the endpoints12. That is:

m=(2x1​+x2​​,2y1​+y2​​)

In this case, we know that m is (−3,−1) and y is (−8,6). We can plug these values into the formula and solve for x:

(−3,−1)−3−6x−1−2−8​=(2x+(−8)​,2−1+6​)=2x−8​=x−8=2=2−1+6​=−1+6=6​

Therefore, x is (2,−8). You can check your answer by plugging it back into the midpoint formula and see if you get m.

I hope this helps

A coin is tossed ten times. The probability of heads on each toss is 0.5. Evaluate the probability of getting exactly 6 heads.

Answers

The probability of getting exactly 6 heads is: 10!/6!(10-6)! * (1/2)^6 (1 - 1/2)^4 = 0.205 or 20.6 %
