at point (0,2) can be reflected across the x-axis PLEASE HELP 50 POINTS true pr false

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

When a point P(x, y) is reflected across the x-axis, all we need to do is to reverse the sign value of the y-coordinate of any given point while the x-value remains the same.

Thus,

The rule to reflect over the x-axis is:

P(x, y) → P'(x, -y)

In our case, the point, let's say A(0, 2), is reflected across the x-axis. Thus, the coordinates of A' will be:

P(x, y) → P'(x, -y)

A(0, 2) → A'(0, -2)

So, YES! point A(0,2) can be reflected across the x-axis and the coordinates of A' will be: A'(0, -2).

one of these students is chosen at random. what is the probability of picking a student who scored above 65

Answers

Answer:

7/18

Step-by-step explanation:

7 students received a score greater than 65, out of a total of 18 students

The probability of picking a student who scored above 65 is 1/3 when one of these students is chosen at random.

To calculate the probability of picking a student who scored above 65, we need to determine the number of students who scored above 65 and divide it by the total number of students.

Looking at the given marks:

46, 65, 54, 57, 62, 73, 73, 47, 69, 48, 63, 68, 55, 48, 58, 71, 76, 70

We can see that the marks above 65 are: 73, 73, 69, 68, 76, 70 (a total of 6 marks).

Now, let's calculate the probability:

Probability = Number of favorable outcomes / Total number of outcomes

Number of favorable outcomes (students who scored above 65) = 6

Total number of outcomes (total number of students) = 18

Probability = 6 / 18

Simplifying the fraction:

Probability = 1 / 3

Therefore, the probability of picking a student who scored above 65 is 1/3.

A computer monitor is 23 inches which is the diagonal distance across the screen.If the screen measures 13 inches in height,what is the actual width of the screen to the nearest inch?

Answers

Answer:

width = 19 inches

Step-by-step explanation:

Pythagorean theorem

23^2 = 13^2+x^2

529 = 169+x^2

x^2 = 360

x = 18.97

The actual width of the screen to the nearest inches will be 18.97 inches.

What is a Pythagoras theorem?

The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

The Pythagoras theorem formula is given as

H² = P² + B²

A PC screen is 23 inches which is the slanting distance across the screen.

If the screen measures 13 inches in height. Then the actual width of the screen will be given as,

23² = 13² + B²

529 = 169 + B²

B² = 360

B = √360

B = 18.97 inches

The actual width of the screen to the nearest inches will be 18.97 inches.
