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.

explain what the Diameter is and how is the radius related to it.

What can the radius and Diameter help us find?

Answers

Answer:

The diameter is any straight line that passes through the center of the circle, which endpoints can lie on. The radius is half the diameter. They help us find the circumference of a circle

Answer:

The diameter is the length of the line through the center that touches two points on the edge of the circle. It is related to the radius because whatever the diameter is is double what the radius is.  In differential geometry, the diameter is an important global Riemannian invariant.

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).

What is Multiplication?

Multiplication in mathematics is the method of finding the product of two numbers. It is usually denoted by a × b.

For two numbers a and b, a × b is defined as either 'a' is added repeatedly upto 'b' times or 'b' is added repeatedly upto 'a' times.

Given that,

Number of miles Emily biked = 13 miles

Number of miles Isaiah biked = 4 times as many miles as Emily

                                                 = 4 × 13

                                                 = 52 miles

Number of miles Andrew biked = 4 times as many miles as Isaiah

                                                     = 4 × 52

                                                     = 208 miles

Hence, Andrew biked the farthest which is equal to 208 miles.
