Answer:
y = -3/2x + 1 1/2
Step-by-step explanation:
the slope would be -3/2 because you have to find the reciprocal and switch the sign. To find the y intercept you would plug in the points to the equation.
6 = -3/2(-3) + b
6 = 4.5 + b
1.5 = b
To serve 1 person at a local restaurant it takes 10 minutes. To serve 5 people it takes 18 minutes. Using the points (1, 10) and (5, 18), find the slope between the two points. The formula for slope is m =y2 - y1/x2 - x1
(a) m=2
(b) m= -2
(c) m= -5
9514 1404 393
Answer:
(a) m = 2
Step-by-step explanation:
The formula tells you the slope is ...
m = (18 -10)/(5 -1) = 8/4
m = 2

Step-by-step explanation:
ive manufacturer wants to know the proportion of new car buyers who prefer foreign cars over domestic. Step 2 of 2: Suppose a sample of 2017 new car buyers is drawn. Of those sampled, 484 preferred foreign over domestic cars. Using the data, construct the 95% confidence interval for the population proportion of new car buyers who prefer foreign cars over domestic cars. Round your answers to three decimal places.
Answer:
0.2305 ; 0.2495)
Step-by-step explanation:
Sample size, n = 2017
Number who preferred foreign over domestic cars, x = 484
Phat = 484 / 2017 = 0.2399603 = 0.240
The confidence interval :
Phat ± Margin of error
Margin of Error = Zcritical * √(phat(1-phat)/n)
Zcritical at 95% = 1.96
1 - phat = 1 - 0. 240 = 0.76
Margin of Error = 1.96 * √((0.240*0.76)/2017) = 0.0095095
Confidence interval :
Lower boundary : 0.240 - 0.0095 = 0.2305
Upper boundary : 0.240 + 0.0095 = 0.2495
(0.2305 ; 0.2495)

What are the mean absolute deviation and population standard deviation of this data set? Round to the nearest tenth if necessary. 2, 4, 6, 9, 14
Answer:
For a data set of N elements:
{x₁, x₂, ..., xₙ}
The mean is:
[tex]M = \frac{x_1 + x_2 + ... + x_n}{N}[/tex]
The mean absolute deviation is:
[tex]MAD = \frac{|x_1 - M| + ... + |x_n - M|}{N}[/tex]
And the population standard deviation is:
[tex]PSD = \frac{\sqrt{|x_1 - M|^2 + ... + |x_n - M|^2} }{\sqrt{N}}[/tex]
In this case, our set has 5 elements, and the set is:
{2, 4, 6, 9, 14}
The mean of this set is:
[tex]M = \frac{2 + 4 + 6 + 9 + 14}{5} = 7[/tex]
The mean absolute deviation is:
[tex]MAD = \frac{|2 - 7| + |4 - 7| + |6 - 7|+ |9 - 7| + |14 - 7| }{5} = 3.6[/tex]
And the population standard deviation is:
[tex]PSD = \sqrt{\frac{|2 - 7|^2 + |4 - 7|^2 + |6 - 7|^2+ |9 - 7|^2 + |14 - 7|^2 }{5}} = 4.2[/tex]
find the product. Simplify

Answer:
7 -1 2/3 4Step-by-step explanation:
The average rate of change of a function f(x) on interval [a, b] is the slope of the line through points (a, f(a)) and (b, f(b)). The slope formula tells you that is ...
m = (f(b) -f(a))/(b -a)
1) The rate of change in the interval [1, 2] is ...
rate of change = (2³ -1³)/(2 -1) = (8 -1)/1 = 7
__
2) rate of change = ((√4 -8) -(√1 -2))/(4 -1) = (-6-(-1))/3 = -5/3
__
3) rate of change = (11 -(-1))/(5 -2) = 4

Answer:
x = 5.9
Step-by-step explanation:
Reference angle = 26°
Opposite = x
Adjacent = 12
Apply TO A:
Tan 26 = Opp/Adj
Substitute
Tan 26 = x/12
Multiply both sides by 12
12*Tan 26 = x
5.85279107 = x
x = 5.9 (nearest tenth)

The mathematics faculty at a college consists of 11 professors, 12 associate professors, 7 assistant professors, and 6 instructorsIf faculty member is selected , find the probability of choosing a professor or an instructor
Answer:
The probability of choosing a professor or an instructor is 47.22%.
Step-by-step explanation:
Given that the mathematics faculty at a college consists of 11 professors, 12 associate professors, 7 assistant professors, and 6 instructors, if a faculty member is selected, to find the probability of choosing a professor or an instructor the following calculation must be performed:
11 + 12 + 7 + 6 = 100
11 + 6 = X
36 = 100
17 = X
17 x 100/36 = X
1700/36 = X
47.22 = X
The probability of choosing a professor or an instructor is 47.22%.

Step-by-step explanation:
Suppose that three microchips in a production run of thirty are defective. A sample of five is to be selected to be checked for defects. (a) How many different samples of five can be chosen from the production run of thirty? 142506 Correct: Your answer is correct. (b) How many samples will contain at least one defective chip? The set of samples that do not contain any defective chips and the set of samples that contain at least one defective chip are disjoint Correct: Your answer is correct. sets. So, the number of samples with at least one defective chip is . (c) What is the probability (as a percent) that a randomly chosen sample of five contains at least one defective chip? (Round your answer to one decimal place.) %
Answer:
a) 142506
b) 61776
c) 0.4333
Step-by-step explanation:
Given
Three microchips in a production run of thirty are defective
The probability of having a defective microchips is 3/30 = 0.1
Probability of having a good microchip is 0.9
a) Possible ways of selecting five sample =
30C5
30*29*28*27*26*25!/25! *5! = 17100720/120 = 142506
b) With one defective microchip
Total sample – sample without any defective microchip
142506 – 37C5
142506 – 80730
61776
c) Probability = 61776/142506 = 0.4333

A town has a population of 18000 and grows at 2% every year. What will be the population after 11 years, to the nearest whole number?
Answer:
~22381
Step-by-step explanation:
a=starting value = 18000
r=rate = 2%=0.02
Exponential Growth:
b=1+r=1+0.02=1.02
b=1+r=1+0.02=1.02
Write Exponential Function:
y=18000(1.02)^x
y=18000(1.02)
x
Put it all together
\text{Plug in time for x:}
Plug in time for x:
y=18000(1.02)^{11}
y=18000(1.02)
11
Evauate:
y= 22380.73755
y=22380.73755
Round:
y\approx 22381
y≈22381

I will use Desmos to get the line.
The slope should be 2
Formula
Slope (m) = ( (y2 - y1) / (x2 - x1) )
Givens
x2 = 8
x1 = 4
y2 = 14
y1 = 6
Solution
m = ( (14 - 6) / ( 8 - 4)
m = 8 / 4
m = 2
