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

Find the slope of the line on the graph below
Answer:
[tex]\frac{6}{5}[/tex]
Step-by-step explanation:
The slope is [tex]\frac{6}{5}[/tex] because rise/run. You rise up on the graph 6 units, and run 5 units to the right (if the graph went to the left), then your slope would be negative.
Another way to double check this is using the slope formula: [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex].
(-3, -3) is x1, y1. & (2, 3) is x2, y2.
So, plugging that into the formula, we get:
[tex]\frac{3-(-3)}{2-(-3)}[/tex] = [tex]\frac{6}{5}[/tex].
Hope that this helped. Have a good day! ☺

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

2. A submarine dives 60 meters in 5 minutes. Find how quickly it dives in feet per second (recall 1 meter = 3.28084 feet). How many feet can it dive in 6 minutes and 34 seconds?
Answer:
258.54 feet
Step-by-step explanation:
Step 1
We convert 60 meters to feet
1 meter = 3.28084 feet
60 meters = x
Cross Multiply
x = 60 × 3.28084 feet
x = 196.8504 feet
60 meters = 196.8504 feet
Step 2
How many feet can it dive in 6 minutes and 34 seconds
We convert 34 seconds to minutes
60 seconds = 1 minute
34 seconds = x
Cross Multiply
60 × x = 34 × 1
x = 34/60
x = 0.567 minutes
So, 6 minutes and 34 seconds = 6 + 0.567 minutes = 6.567 minutes.
60 meters in 5 minutes.
60 meters = 196.8504 feet
Hence:
5 minutes = 196.8504 feet
6.567 minutes = x
Cross Multiply
5x = 6.567 × 196.8504 feet
5x = 1292.7165768 feet
x = 1292.7165768/5
x = 258.54331536 feet
Approximately = 258.54 feet
Therefore, the submarine can dive 258.54 feet in 6 minutes 34 seconds
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?
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.
