Zoe just lit a new candle and then let it burn all the way down to nothing. The length
of the candle remaining unburned, in inches, can be modeled by the equation
L = 9 – 0.5t, where t represents the number of hours since the candle was lit.
What is the y-intercept of the equation and what is its interpretation in the context of
the problem?
Answers
Answer:
9 which represents the the original length of the new candle
Step-by-step explanation:
Since there were 9 inches of candle remaining after 0 hours of burning, that means 9 represents the initial length of the candle, in inches.

Step-by-step explanation:
In mathematics, the procedure to select k items from n distinct items, without replacement, is known as combinations.
The formula to compute the combinations of k items from n is given by the formula:
[tex]{n\choose k}=\frac{n!}{k!\cdot(n-k)!}[/tex]
(a)
Compute the number of ways to select 9 applicants from 100 as follows:
[tex]{100\choose 9}=\frac{100!}{9!\cdot(100-9)!}[/tex]
[tex]=\frac{100!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92\times 91!}{9!\times 91!}\\\\=\frac{100\times 99\times 98\times 97\times 96\times 95\times 94\times 93\times 92}{9!}\\\\=1902231808400[/tex]
(b)
Compute the number of ways to select 6 people from 9 as follows:
[tex]{9\choose 6}=\frac{9!}{6!\cdot(9-6)!}[/tex]
[tex]=\frac{9!}{6!\times 3!}\\\\=\frac{9\times 8\times 7\times 6!}{6!\times 3!}\\\\=\frac{9\times 8\times 7}{3!}\\\\=84[/tex]
(c)
Compute the number of ways to select top 3 candidates from 6 as follows:
[tex]{6\choose 3}=\frac{6!}{3!\cdot(6-3)!}[/tex]
[tex]=\frac{6!}{3!\times 3!}\\\\=\frac{6\times 5\times 4\times 3!}{3!\times 3!}\\\\=\frac{6\times 5\times 4}{3!}\\\\=20[/tex]

Are these lines parallel, perpendicular, or neither? 3y=x+4 and 3x+y=1
Answers
Answer:
perpendicular
Step-by-step explanation:
3y = x + 4 in slope intercept form y = 1/3x +4/3
3x + y = 1 in slope intercept form y = -3x +1
the slopes are negative reciprocals of each other so they are perpendicular
Answer:
These lines are perpendicular
Step-by-step explanation:
3y=x+4
[tex]y = \frac{1}{3}x+\frac{4}{3}[/tex]
Slope (m1) = 1/3
3x+y=1
y = -3x + 1
Slope (m2) = - 3
m1 * m2 = [tex]\frac{1}{3}* -3[/tex]
= -1
So, these lines are perpendicular.
If product of two slopes is (-1), then they are perpendicular lines.
If both lines have same slope, then they are parallel.

Find the next three terms of the following arithmetic sequence -2, -5, -8, -11,
Answers
Answer: -14, -17, and -20
Step-by-step explanation: Study the sequence.
Notice that each number is 3 less than the number before it.
In other words, -2 - 3 is -5, -5 - 3 is -8, and -8 - 3 is -11.
Now, if we continue with this same sequence,
-11 - 3 is -14, -14 - 3 is -17, and -17 - 3 is -20.
So the next three numbers are -14, -17, and -20.

Property of an isosceles triangle,
Opposite angles of the equal sides in an isosceles triangle are equal in measure.
m∠D = m∠F
(2x + 8) = (3x + 4)
3x - 2x = 8 - 4
x = 4
m∠D = m∠F = (3×4 + 4)°
= 16°
m∠D = m∠F = 16°
Since, sum of interior angles of a triangle = 180°
m∠D + m∠E + m∠F = 180°
16° + m∠E + 16° = 180°
m∠E = 180° - 32°
m∠E = 148°

Need help finding the parallel and perpendicular slope
Answers
Answer:
Step-by-step explanation:
(x₁, y₁) = (19 , -4) & (x₂ ,y₂) = (17, -20)
[tex]Slope =\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]= \frac{-20-[-4]}{17-19}\\\\= \frac{-20+4}{17-19}\\\\= \frac{-16}{-2}\\\\= 8[/tex]
m = 8
Parallel lines have same slope.
Parallel slope = 8
Slope of perpendicular line = [tex]\frac{-1}{m}[/tex]
Perpendicular slope = [tex]\frac{-1}{8}[/tex]
Penny Weights, use the weights of the post 1983 pennies to construct a 98% confidence interval estimate of the standard deviation of the weights of all post-1983 pennies. S=0.0165 n=37. Find confidence interval. a. 0.01231 < Ï < 0.2111 b. 0.01239 < Ï < 0.02111 c. 0.1391 < Ï < 0.2311 d. 0.001219 < Ï < 0.002111
Answers
Answer:
c. 0.1391 < Ï < 0.2311
Step-by-step explanation:
The formula for Confidence Interval is given as:
Mean ± z × Standard deviation/√n
Z score for 98% confidence interval = 2.326
Mean = Significance level = 100% - 98%
= 2% = 0.02
Standard deviation = S=0.0165
n= 37
Hence,
Confidence Interval =
0.02 ± 2.326 × 0.0165/√37
0.02 ± 0.0063094687
Confidence Interval
0.02 - 0.0063094687
= 0.1391
0.02 ± 0.0063094687
= 0.2311
Hence, the Confidence Interval = (0.1391, 0.2311)
= c. 0.1391 < Ï < 0.2311
