Answer:
I guess that you want to model the elevation of Lake Sam Rayburn.
During the summer, it is 165 ft above the sea level (the sea level is our position 0ft).
If it does not rain, the elevation of the lake decreases by 0.5ft each week.
So if we assume that there is no rain, we can write the elevation fo the lake as a linear relationship with slope equal to -0.5ft and y-intercept equal to 165ft.
L(w) = 165ft - 0.5ft*w
Where w is the number of weeks without rain, if we have 0 weeks without rain, then the level of the lake remains constant at 165ft above sea level,
L(0) = 165ft - 0.
Answer:
Equation which can be used to find the number of weekly payments w
is 300 = 60 + 3 w.
Step-by-step explanation:
Here, the selling price of the TV =$300
The initial TV payment = $60
Per week payment of TV = $30
The number of weeks, the payment is made = w
So, the amount paid for TV in w weeks = w x ( Payment in 1 week)
= w x ( $30) = 30 w
So, The total SP of TV = Initial Payment + Payment made in w weeks
⇒ 300 = 60 + 3w
Hence, equation which can be used to find the number of weekly
payments w is 300 = 60 + 3 w.
Answer:
Part A - D:8
Part B - C:140°
<h3>Solving/Reasoning:</h3>
Part A: Vertical angles are always congruent.
Part B: If angles are supplementary, they need to equal 180 when added together. Since we know angle A is 40, we can subtract it from 180 and figure out what is left over that should be angle B.
40+B=180
B=180-40
B=140
Answer:
value we use for z value of sample test is r/n
Step-by-step explanation:
Given data
proportion p
trials = n
successes = r
to find out
what value we use for z value of sample test
solution
here
we know that
Probability of a success in single trail test = Number of successes/Number of trails
Probability of a success in single trail = r / n
so that
value we use for z value of sample test is r / n
