How do you plot a linear graph​

Mathematics
1 answer:
dlinn [17]3 years ago
4 0

Step-by-step explanation:

You can plot linear graph using two point (x1,y1) and (x2,y2), where x1, y1, x2 and y2 are real numbers.

or

using slope intercept form y = mx + b, where m is the slope and b is y-intercept.

A student walk 60m on a bearing
Katena32 [7]

Answer:

d = 234.6 m

Step-by-step explanation:

You can consider a system of coordinates with its origin at the beginning of the walk of the student.

When she start to walk, she is at (0,0)m. After her first walk, her coordinates are calculated by using the information about the incline and the distance that she traveled:

x_1=60cos28\°=52.97m\\\\y_1=60sin28\°=28.16m

she is at the coordinates (52.97 , 28.16)m.

Next, when she walks 180m to the east, her coordinates are:

(52.97+180 , 28.16)m = (232.97 , 28.16)m

To calculate the distance from the final point of the student to the starting point you use the Pythagoras generalization for the distance between two points:

d=\sqrt{(x-x_o)^2+(y-y_o)^2}\\\\x=232.97\\\\x_o=0\\\\y=28.16\\\\y_o=0\\\\d=\sqrt{(232.97-0)^2+(28.16-0)^2}m=234.6m

The displacement of the student on her complete trajectory was of 234.6m

A local country club has a membership of 600 and operates facilities that include an 18-hole championship golf course and 12 ten
shusha [124]

Answer:

0.45 = 45% probability that the member uses the golf course but not the tennis courts

Step-by-step explanation:

I am going to solve this question using the events as Venn sets.

I am going to say that:

Event A: Uses the golf courses.

Event B: Uses the tennis courts.

5% use neither of these facilities.

This means that P(A \cup B) = 1 - 0.05 = 0.95

75% use the golf course, 50% use the tennis courts

This means, respectively, by:

P(A) = 0.75, P(B) = 0.5

Probability that a member uses both:

This is P(A \cap B). We have that:

P(A \cap B) = P(A) + P(B) - P(A \cup B)

So

P(A \cap B) = 0.75 + 0.5 - 0.95 = 0.3

What is the probability that the member uses the golf course but not the tennis courts?

This is P(A - B), which is given by:

P(A - B) = P(A) - P(A \cap B)

So

P(A - B) = 0.75 - 0.3 = 0.45

0.45 = 45% probability that the member uses the golf course but not the tennis courts
