Find the equation of the straight line that passes through the points (1, 10) and (3, 2)
ANSWER ASAP
Answer:
y = -4x+14
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
m = (2-10)/(3-1)
=-8/2
= -4
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -4x+b
Substitute a point into the equation
10 = -4(1)+b
Add 4 to each side
14 = b
y = -4x+14

Answer:
a) true.
if 3 can divide a without remainder, then a = 3×x.
doubling that number makes it 2×3×x. because of that still included factor 3, it is still divisible by 3 without remainder.
b) false.
example :
a=6, b=4, c=3
bc = 12
6 can divide 12 without remainder, but 6 cannot do that with 4 and not with 3.
or
a=7, b=35, c=10
bc=350
7 can divide 350 without remainder, and can do that also with 35, but not with 10.

Put x = 1. y = 5
⇒ 5 = 3 × 1 + 2
⇒ 5 = 5
Thus, It is solution of linear equation.
⇒ y = 3x + 2
Put x = 2. y = 8
⇒ 8 = 3 × 2 + 2
⇒ 8 = 8
Thus, It is solution of linear equation.
⇒ y = 3x + 2
Put x = 3, y = 10
⇒ 10 = 3 × 3 + 2
⇒ 10 ≠ 11
Thus, It is not solution of linear equation.
Thus, The correct coordinates which is NOT a solution to the linear equation y = 3x+2 is,

x double bar =
LCL =
UCL =
Answer:
x double bar = 4
LCL = - 2
UCL = 10
Step-by-step explanation:
The C - chart :
The control limit = xbar
xbar = mean = ΣX / n
The upper and lower control limit :
Xbar ± 3√xbar
Xbar = Σx / n = 100 / 25 = 4
Hence,
x double bar = 4
LCL = Xbar - 3√xbar = 4 - 3√4 = 4 - (3*2)
LCL = 4 - 6 = -2
UCL = Xbar + 3√xbar = 4 + 3√4 = 4 + (3*2)
LCL = 4 + 6 = 10
Calculate the mean, the variance, and the standard deviation of the following discrete probability distribution. (Negative values should be indicated by a minus sign. Round intermediate calculations to at least 4 decimal places. Round your final answers to 2 decimal places.)

Mean
Variance
Standard deviation
Mean = 24.47
Variance = 108.31
Standard deviation = 10.41
Step-by-step explanation:The probability distribution table has been attached to this response.
(1) To calculate the mean (m)
(a) First multiply each of the values of x by their corresponding probability values.
This is shown in the third column of the table.
(b) The sum of the results in the third column gives the mean of the distribution. i.e
m = ∑xP(x) = 11.52 + 9.36 + 3.15 + 0.44
m = 24.47
(2) To calculate the variance (σ²).
(a) First find the square of the difference between the values of x and the mean (m) calculated in (1b) above. i.e
(x - m)²
The result is shown in the fourth column of the table.
(b) Next, multiply each of the results in the fourth column (x - m)², by their corresponding probability values P(X = x). i.e
(x - m)²(P(X = x))
The result is shown in the fifth column of the table.
(c) Now find the variance (σ²) which is the sum of the results in the fifth column. i.e
σ² = ∑(x - m)²(P(X = x)) = 42.5411 + 0.8427 + 18.8330 + 46.0923
σ² = 108.3091
σ² = 108.31 [to 2 decimal places]
(3) To calculate the standard deviation (σ)
The standard deviation is the square root of the variance of the distribution. Calculate this by finding the square root of the result in (2c) above.
σ = √σ²
σ = [tex]\sqrt{108.31}[/tex]
σ = 10.4072
σ = 10.41 [to 2 decimal places]

The value of solution of quadratic function is,
⇒ x = (5 ± √33) / 2

Given that;
The quadratic function is,
⇒ x² - 5x - 2 = 0
Now, We can simplify as;
⇒ x² - 5x - 2 = 0
⇒ x = - (- 5) ± √(-5)² - 4×1×- 2 / 2
⇒ x = (5 ± √33) / 2
Thus, The value of solution of quadratic function is,

A scientist is studying the growth of a particular species of plant. He writes the following equation to show the height of the plant f(n), in cm, after n days:
f(n) = 10(1.02)n
Part A: When the scientist concluded his study, the height of the plant was approximately 11.04 cm. What is a reasonable domain to plot the growth function? (4 points)
Part B: What does the y-intercept of the graph of the function f(n) represent? (2 points)
Part C: What is the average rate of change of the function f(n) from n = 1 to n = 5, and what does it represent? (4 points)
Answer:
Step-by-step explanation:
11.04 = 10(1.02)^n
1.104 = 1.02^n
ln 1.104 = ln 1.02^n
ln 1.104 = n ln 1.02
n = ln 1.104/ ln 1.02
n = 4.99630409516
4.99 can be rounded to 5.
So a reasonable domain would be 0 ≤ x < 5
PART B)
f(0) = 10(1.02)^0
f(0) = 10(1)
f(0) = 10
The y-intercept represents the height of the plant when they began the experiment.
f(1) = 10(1.02)^1
f(1) = 10(1.02)
f(1) = 10.2
(1, 10.2)
f(5) = 10(1.02)^5
f(5) = 10(1.1040808)
f(5) = 11.040808
f(1)=10(1.02)^1
f(1)=10.2
Average rate= (fn2-fn1)/(n2-n1)
=11.04-10.2/(5-1)
=0.22
the average rate of change of the function f(n) from n = 1 to n = 5 is 0.22.

What are the solutions to
96x(730) = (85/x)(15)
in decimal form?
Answer:
[tex]x = 0.1349[/tex]
Step-by-step explanation:
Given
[tex]96x (730) = (85/x)(15[/tex]
Multiply both sides by x
[tex]96x^2 (730) = 85 * 15[/tex]
[tex]96x^2 (730) = 1275[/tex]
Rewrite as:
[tex]96*730x^2 = 1275[/tex]
[tex]70080x^2 = 1275[/tex]
Divide by 70080
[tex]x^2 = 0.01819349315[/tex]
Take square roots of both sides

If in the numerator i had a imaginary number when factoring what should i do???
Answer:
we need to factorise if imaginary number is in the denominator. no action is required if its in the numerator.
you can factorise an imaginary number by multiplying both the numerator and denominator by the conjuncate of the complex number
for instance,
we've given a complex number as follows
[tex] \frac{x}{3x + 4i} [/tex]
factorising
[tex] \frac{x}{3x + 4i} \times \frac{3x - 4i}{3x - 4i} [/tex]
as 3x -4i is the conjugate of 3x + 4i
and 4i is the imaginary number
[tex] \frac{ x(3x - 4i)}{9x {}^{2} - 4 {i}^{2} }[/tex]
and since i² = -1
[tex]\frac{ x(3x - 4i)}{9x {}^{2} + 4}[/tex]
hence factorised
John is a quarterback. This year, he completed 350 passes, which is 70, percent of all the passes he's attempted this year.
How many passes has John attempted this year?
Answer:
John attempted 500 passes this year
Step-by-step explanation:
To sum up the question, it is basically asking what number has 350 as 70% of it.
We know that:
350 is 70% of some number.
Convert 70% to fraction:
70% = 7/10
Divide:
350 ÷ 7/10 = 500
So 350 is 70% of 500
CHECK THE ANSWER:
10% of 500 is 50
To find 70% of 500, multiply:
50 x 7 = 350

The total population of ethnic Southeast Asian students from Burma, Laos, Thailand, Vietnam, and Kampuchea at your university is currently 100 students. The administration of the university wants to increase the diversity of the student body and decides to increase the number of students from Southeast Asia by 8 percent each year, (over the prior year's enrollment) for a period of 15 years. How many students from Southeast Asia will be enrolled at your university after the 15 year period
Answer:
the number of students that enrolled after 15 year is 317
Step-by-step explanation:
The computation of the number of students that enrolled after 15 year is shown below;
We know that
Future value = Present value × (1 +rate of interest)^number of years
= 100 × (1+8%)^15
= 100 × 1.08^15
= 317
Hence, the number of students that enrolled after 15 year is 317
