What is the equation of the line that passes through the point (-3, 1) and has a
slope of -2?
Answer:
y = -2x - 5
Step-by-step explanation:
x1 = -3 , y1 = 1 ; m = -2
point slope form : y - y1 = m(x -x1)
y - 1 = -2(x - [-3])
y - 1 = -2(x + 3)
y - 1 = -2x + 3*(-2)
y - 1 = -2x - 6
y = -2x - 6 + 1
y = -2x - 5
line parallel to y=8-1/8x
Answer:
Y = (-1/8) X + C is the equation of a line parallel to y=8-1/8x
Step-by-step explanation:
Complete question.
Find the line parallel to y=8-1/8x
Solution
For two lines to be parallel to each other it is essential that their slopes must be same
For any line of the form
Y = mX +b
m is the slope
Here the equation of given line is y=8-1/8x
on rearranging, we get
Y = (-1/8) X + 8
here m = (-1/8)
Hence, line parallel to y=8-1/8x is any line with slope equal to (-1/8)
Or we can say that equation of parallel line would be
Y = (-1/8) X + C

and AD = 12, what is the length of AC?
A
12
D
24
Answer: x=48
Step-by-step explanation:
The length AC of the right-angle triangle will be 48 units.
What is a right-angle triangle?It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.
According to the hypotenuse-leg (HL) principle, a right triangle is harmonious if each of its third side and legs are congruent with its equivalent hypotenuse and legs in another right triangle. The HL theorem proves that these triangles are identical.
AC / AB = AB / AD
AC / 24 = 24 / 12
AC = 48 units
The length AC of the right-angle triangle will be 48 units.

Solve for x. 20x + 5 =5x+65
Answer:
x = 4
Step-by-step explanation:
subtract 5 from all sides
20x+5-5=5x+65-5
simplify
20x=5x+60
subtract 5x from both sides
20x-5x=5x+60-5x
simplify again
15x=60
Divide both sides by 15
15x/5 = 60/15
lastly simplify to get your answer of
x = 4

A 20-minute consumer survey that included a $5 Starbucks gift card was emailed to 500 adults aged 25-34. The survey resulted in 65 responses. The same 20-minute consumer survey was emailed to 500 adults aged 25-34 without the Starbucks gift card. The survey resulted in 45 responses. We would like to know if the inclusion of a Starbucks gift card led to any change in survey response rate. Which of the following hypotheses should be used?
A. Null Hypothesis: mul (average number of responses with Starbucks gift card)<= muo(average number of responses without Starbucks gift card) Alternative Hypothesis: mu1 ( average number of responses with Starbucks gift card)> muo(average number of responses without Starbucks gift card)
B. Null Hypothesis: mu1 (average number of responses with Starbucks gift card)= mud (average number of responses without Starbucks gift card) Alternative Hypothesis: mu1 ( average number of responses with Starbucks gift card) \= mul ( average number of responses without Starbucks gift card) * \= means "not equal to"
C. Null Hypothesis: pi1 (rate with Starbucks gift card)= pi2 (rate without Starbucks gift card) Alternative Hypothesis: pi1 (rate with Starbucks gift card) (= pi2 (rate without Starbucks gift card) * \= means "not equal to"
D. Null Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card)<=0 Alternative Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card) > 0
Answer:
D. Null Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card)<=0 Alternative Hypothesis: pi1 (rate with Starbucks gift card) - pi2 (rate without Starbucks gift card) > 0
Step-by-step explanation:
The test described above test the difference in proportion :
With Starbucks gift card :
x1 = 65 n1 = 500
Phat 1 = x1 / n1
Phat 1 = 65 /500 = 0.13
Phat1
Without Starbucks gift card :
x2 = 45 n2 = 500
Phat1 = x2 / n2
Phat 2 = 45 / 500 = 0.09
To test the difference in proportion :
Phat 1 > Phat 2 (alternative)
Null takes the stance that there is no difference in proportion
Phat1 - phat2 <=0
Alternative claims that there is difference on proportion such that phat 1 is greater than phat 2
Phat 1 - phat > 0

A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 centimetres and a height of 2 centimetres. How much wax will the company need to make 270 candles?
Use 3.14 for π, and do not round your answer.
Answer:
270 = 15,268.14030 in³
Step-by-step explanation:
A company makes wax candles in the shape of a cylinder. Each candle has a diameter of 6 inches and a height of 2 inches. How much wax will the company need to make 270 (use 3.14 for n, and do not round your answer)?
Volume = π r² h __ 3.14 * 9 * 2 = 56.52 in³ * 270 = 15,260.4 in³
Using a typical ten digit calculator
3.141592654 * 9 * 2 = 56.54866777 in³ * 270 = 15,268.14030 in³ (rounded)
Volume of cylinder = pi x r^2 x height
Volume = 3.14 x 3^2 x 2 = 56.52 cubic cm.
Multiply the volume of a cylinder by total candles:
56.52 x 270 = 15,260.4 cubic cm
