Answer:
The graph in the attached figure
Step-by-step explanation:
we have
y=x+2.05
This is a linear equation ( equation of a line)
To graph the line find the intercepts
<u>The y-intercept</u> is the value of y when the value of x is equal to zero
For x=0
y=0+2.05=2.5
The y-intercept is the point (0,2.05)
<u>The x-intercept</u> is the value of x when the value of y is equal to zero
For y=0
0=x+2.05
x=-2.05
The x-intercept is the point (-2.05,0)
To graph the line plot the intercepts and then join the points
using graphing tool
see the attached figure
Y₂-y₁ ÷x₂-x₁ =
(7.5 - 24) ÷ (36-5) =
-16.5 ÷ 31 = -16.5/31 ≈ -0.5322480
Or as a fraction: -33/62
Answer:
1/5
Step-by-step explanation:
Use Pythagoras theorem
Answer:
$705.79.
Step-by-step explanation:
The formula is
Amount = P(1 + r/100) ^ t so
Amount = 500 (1 + 9/100)^4
= $705.79.
Answer:
- <u><em>About 0.22</em></u>
Explanation:
There are two sets:
- Set W of incoming seniors who took AP World History, and
- Set E of incoming seniors who took AP European History
And there is a subset, which is the intersection of those two sets:
- Subset W ∩ E of senior students who took both.
The incoming seniors who are allowed to enroll in AP U.S. History, call them the subset S, is the set of those students that belong to W or E or both W ∩E.
By property of sets:
- S = W + E - W∩E = 175 + 36 - 33 = 178
Then, 178 out of 825 incoming seniors took one or both courses, and the desired probability of a randomly selected incoming senior is allowed to enroll in AP U.S. History is:
