a) Find the slope, x-intercept, y-intercept of the line (L):
3x+4y-6= 0 and draw its graphs.
b) Find the equation of a line perpendicular to the line (L) in part (a) and
passing through the point (1, -2).
Answer: 2, 1.5 , -0.75
(b) [tex]4x-3y-10=0[/tex]
Step-by-step explanation:
Given
line is [tex]3x+4y-6=0[/tex]
Converting it into intercept form
[tex]\Rightarrow 3x+4y=6\\\\\Rightarrow \dfrac{3x}{6}+\dfrac{4y}{6}=\dfrac{6}{6}\\\\\Rightarrow \dfrac{x}{2}+\dfrac{y}{1.5}=1[/tex]
So, the x-intercept is [tex]2[/tex] and y-intercept is [tex]1.5[/tex]
The slope is given by
[tex]-\dfrac{\frac{1}{2}}{\frac{1}{1.5}}=-0.75[/tex]
(b) the line perpendicular to the above line and passing through [tex](1,-2)[/tex]
The slope of the required line
[tex]m=-\dfrac{1}{-0.75}\\\\m=\dfrac{4}{3}[/tex]
Equation of the line is given by
[tex]\Rightarrow \dfrac{y-(-2)}{x-1}=\dfrac{4}{3}\\\\\Rightarrow 3y+6=4x-4\\\Rightarrow 4x-3y-10=0[/tex]

Write an exponential function in the form y
and (5,2187)
9514 1404 393
Answer:
y = 9(3^x)
Step-by-step explanation:
We assume you want a function in the form ...
y = a(b^x)
that passes through points (0, 9) and (5, 2187).
Filling in the given point values, we have ...
9 = a(b^0) = a
2187 = a(b^5) = 9(b^5) . . . . using the above value of 'a'
Dividing the second equation by 9 and taking the 5th root, we find b.
(2187/9) = b^5
243^(1/5) = b = 3
The exponential function is ...
y = 9(3^x)
Mandy and Randy are each playing with a beach ball. Mandy's ball has a diameter of 12 inches. Randy's ball has a diameter that is twice as large as Mandy's ball. How much larger is the volume of Randy's ball? Show and explain your reasoning.
Answer:
Randy's ball is 904.78 larger than Mandy's.
Step-by-step explanation:
Using math, we find that Mandy's ball is 904.78 inches in volume and if Randy's is twice the size that's, 904.78 x 2 = 1809.56. so Randy's ball is 904.78 larger than Mandy's

A class with 25 students randomly selects a different student each week to bring a class snack. Of the students,
8% have food allergies. Let T be the number of weeks until a student with a food allergy is selected to bring the
snack
What type of variable is T?
Need help!!!
Answer:
Neither
Step-by-step explanation:
The variable T (weeks until getting food allergic student) follows Geometric Distribution
Given : 25 students & different student chosen to bring snack each week, 8% students have food allergies
To find : T ie number of weeks until student with food allergy is selected, follows which statistical distribution
Let's assume the probability of success be probability of choosing a student with food allergy . Also, let the number of weeks refer to number of trials. Binomial Distribution shows probability of getting 'x' successes out of n trials, when probability of success and failure 'p' & 'q' are given. Geometric Distribution is a type of negative binomial distribution, denoting number of trials needed to achieve a success.In this case, we need to find number of weeks trials, needed to achieve a success - ie a student with food allergy.
Hence this follows a Geometric Distribution.

A manufacturer that specializes in hamburgers made 200 hamburger patties. The manufacturer claims that the weights of these patties are approximately normally distributed with a mean of 8 ounces and a standard deviation of 0.54 ounces. You go to a store and buy 5 randomly selected hamburgers and find that the mean weight of your 5 hamburgers is only 7.6 ounces.
Answer:
The answer is "Parameter: 8 ounces and Statistics: 7.6 ounces"
Step-by-step
Amount of restaurant hamburger packers = 200
Mean weight of its patties = 8 ounces
Specification Patty Deviation=0.54 ounces
Those who went to the supermarket and bought five hamburgers picked randomly.
The important weight of hamburgers = 7.6 ounces
For this case, we need to classify the sample population and test statistics.
The group comprises all elements that may probably be predefined, while a small number of findings from this wider group are taken from either the sample. The restaurants achieved a list of 200 hamburgers. Consequently, the population is made up of 200 patties. From 200 hamburgers accessible, I visit the shop or pick 5 hamburgers. So, five hamburgers arbitrarily selected are samples.
parameters:
The parameter is known for just about any value or metric representing or reflecting the entire nation. They know from the information that the average weight of 200 burger patties is eight pounds. Because as mean(center) of a whole population is 8 ounces, this is a parameter.
Statistics:
The statistic is any quality or measure defining or representing its specimen. We purchased 5 randomly selected hamburgers, which meant 7.6 ounces for mean weight. 7.6 is a statistic, thus.

9x2 + 4(y - 2)2 = 36
x² = 2y
Answer:
[tex]x =2[/tex]
[tex]y =2[/tex]
Step-by-step explanation:
Given
[tex]9x^2 + 4(y - 2)^2 = 36[/tex]
[tex]x^2 = 2y[/tex]
Required
Solve
Substitute: [tex]x^2 = 2y[/tex] in [tex]9x^2 + 4(y - 2)^2 = 36[/tex]
[tex]9*2y + 4(y-2)^2 = 36[/tex]
[tex]18y + 4(y-2)^2 = 36[/tex]
Open bracket
[tex]18y + 4[y^2-2y - 2y + 4] = 36[/tex]
[tex]18y + 4[y^2-4y + 4] = 36[/tex]
Open bracket
[tex]18y + 4y^2-16y + 16 = 36[/tex]
Collect like terms
[tex]4y^2+18y-16y + 16 - 36 = 0[/tex]
[tex]4y^2+2y-20= 0[/tex]
Divide through by 2
[tex]2y^2+y-10= 0[/tex]
Expand
[tex]2y^2+5y - 4y-10= 0[/tex]
Factorize
[tex]y(2y + 5) - 2(2y + 5) = 0[/tex]
Factor out 2y + 5
[tex](y -2)(2y + 5) = 0[/tex]
Split
[tex]y - 2 =0\ or\ 2y + 5 = 0[/tex]
Solve for y
[tex]y =2 \ or\y = -\frac{5}{2}[/tex]
We have:
[tex]x^2 = 2y[/tex]
Make x the subject
[tex]x = \sqrt{2y[/tex]
The above is true for positive y values.
So: [tex]y =2[/tex]
This gives
[tex]x = \sqrt{2*2[/tex]
[tex]x = \sqrt{4[/tex]
[tex]x =2[/tex]
A salesperson earns $300 per week, plus a 25% commission on each sale made. How much would the salesperson earn if he sold $650 worth of merchandise in one week?
Round to two decimal places
Answer:
$800 = $300 +.05(x), x being the amount that must be sold
Subtract 300 from both sides
$500= .05(x)
Divide by .05
x=$10000

A line passes through the point (-1, -7) and has a slope of -8.
Write an equation in slope-intercept form for this line.
9514 1404 393
Answer:
y = -8x -15
Step-by-step explanation:
It can be useful to start with the point-slope form when you are given a point and a slope.
y -k = m(x -h) . . . . . line with slope m through point (h, k)
For the given line, this equation is ...
y +7 = -8(x +1)
y = -8x -8 -7 . . . . eliminate parentheses, subtract 7
y = -8x -15 . . . . . slope-intercept form
. (0.5 point) We simulate the operations of a call center that opens from 8am to 6pm for 20 days. The daily average call waiting times are reported below for these 20 simulated days: 24.16 20.17 14.60 19.79 20.02 14.60 21.84 21.45 16.23 19.60 17.64 16.53 17.93 22.81 18.05 16.36 15.16 19.24 18.84 20.77 Due to a budget cut, the call center has now to downsize and the simulation model is used to predict the effect. We again simulate the call center for 20 days and now the daily average call waiting times are: 19.81 18.39 24.34 22.63 20.20 23.35 16.21 21.73 17.18 18.98 19.35 18.41 20.57 13.00 17.25 21.32 23.29 22.09 12.88 19.27 Compute a 95% t-confidence interval to decide if the change in the call waiting time is statistically significant.
Answer:
The 95% t-confidence interval for the difference in mean is approximately (-2.61, 1.16), therefore, there is not enough statistical evidence to show that there is a change in waiting time, therefore;
The change in the call waiting time is not statistically significant
Step-by-step explanation:
The given call waiting times are;
24.16, 20.17, 14.60, 19.79, 20.02, 14.60, 21.84, 21.45, 16.23, 19.60, 17.64, 16.53, 17.93, 22.81, 18.05, 16.36, 15.16, 19.24, 18.84, 20.77
19.81, 18.39, 24.34, 22.63, 20.20, 23.35, 16.21, 21.73, 17.18, 18.98, 19.35, 18.41, 20.57, 13.00, 17.25, 21.32, 23.29, 22.09, 12.88, 19.27
From the data we have;
The mean waiting time before the downsize, [tex]\overline x_1[/tex] = 18.7895
The mean waiting time before the downsize, s₁ = 2.705152
The sample size for the before the downsize, n₁ = 20
The mean waiting time after the downsize, [tex]\overline x_2[/tex] = 19.5125
The mean waiting time after the downsize, s₂ = 3.155945
The sample size for the after the downsize, n₂ = 20
The degrees of freedom, df = n₁ + n₂ - 2 = 20 + 20 - 2 = 38
df = 38
At 95% significance level, using a graphing calculator, we have; [tex]t_{\alpha /2}[/tex] = ±2.026192
The t-confidence interval is given as follows;
[tex]\left (\bar{x}_{1}- \bar{x}_{2} \right )\pm t_{\alpha /2}\sqrt{\dfrac{s_{1}^{2}}{n_{1}}+\dfrac{s_{2}^{2}}{n_{2}}}[/tex]
Therefore;
[tex]\left (18.7895- 19.5152 \right )\pm 2.026192 \times \sqrt{\dfrac{2.705152^{2}}{20}+\dfrac{3.155945^2}{20}}[/tex]
(18.7895 - 19.5125) - 2.026192*(2.705152²/20 + 3.155945²/20)^(0.5)
The 95% CI = -2.6063 < μ₂ - μ₁ < 1.16025996668
By approximation, we have;
The 95% CI = -2.61 < μ₂ - μ₁ < 1.16
Given that the 95% confidence interval ranges from a positive to a negative value, we are 95% sure that the confidence interval includes '0', therefore, there is sufficient evidence that there is no difference between the two means, and the change in call waiting time is not statistically significant.

Miss Lin bought 40 raisin, butter and curry buns for a class party. The ratio
of the number of raisin buns to the number of butter buns to the number of
curry buns was 7:5:8. Find the number of curry buns Miss Lin bought.
Answer:
Number of curry buns is 16.
Step-by-step explanation:
Total number of buns =40.
Ratio of number of raisin buns to the number of butter buns to the number of curry buns = 7:5:8
Let number of raisin buns = 7X.
Let number of butter buns =5X.
Let number of curry buns = 8X.
Therefore,
7X+5X+8X = 40
20X = 40
X= (40/20) = 2.
Therefore number of curry buns =8X = 8×2 =16.

Do all lines have a y-intercept? Why or why not?
Answer:
Not all lines have an x- and y-intercept. This line does not cross the x-axis. Similarly, the line x=2 is a vertical line which does not cross the y-axis.
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
I am assuming you are talking about linear functions. When it comes to them, most of them have a y-intercept, and if they do, they are counted as functions. Linear functions must have some sort of slope, but because there is a special line that does not have a slope, then it is not a function. And since it does not have a slope, it also does not hit the y-axis. Usually, the equation is set to equal y, for example:
y = 1
But, a line that does not have a slope is equal to x, like:
x = 1
x = 1 is a completely vertical line that is parallel to the y-axis, which means it does not have a y-intercept.
To experiment this, you can try it in Desmos, which is a secure graphing website. I hope this helps you!
