What is an equation of the line that passes through the point ( 1 , 7 ) and is parallel to the line
3x−y=1?
Answers
Answer:
(y-1)= 3(x-7)
Step-by-step explanation:
1. you put the equation given in slope intercept form so y=3x-1.
2. you find the slope, parellel lines have the same slope so the slope for the new equation will remain 3.
3. then you write the point-slope form equation
4) make sure to plug in the x1 and y1 values from the coordniates given
The required equation of the line is given as 3x - y = -4.
Given that,
The equation of the line that passes through the point ( 1, 7 ) and is parallel to the line 3x−y = 1 is to be determined.
The slope of the line is a tangent angle made by line with horizontal. i.e. m = tanx where x in degrees.
here,
The standard equation of the line is given as,
y = mx + c,
Since the line is parallel to line 3x - y = 1 whose slope is m = 3, and also the slope of the parallel line are equal.
so,
y = 3x + c
Put points (1, 7) in the above equation,
7 = 3 + c
c = 4
y = 3x + 4
Thus, the required equation of the line is given as 3x - y = -4.

Answers
Answer:
h=14
Step-by-step explanation:
7h-5(3h-8)=-72
Combine Like Terms
-8h+40=-72
Subtract 40 on both sides
-8h+40 -40 = -72 -40
Then we get
-8h/8=-112/8 so we divide by 8
h=14
Steps
7h-5(3h-8)=-72 remove parentheses
7h-15h+40=-72 collect like terms
-8h+40=-72 move constant to right
-8h=-72-40
-8h=-112 divide both sides by 8
-8h/-8 = -112/-8
H=14

Shares in stock of a new company are selling for $3.75 per share. An investor has $800. Which inequality can be solved to show the number of shares s he can buy?
Answers
Given:
Price of each share = $3.75
Total amount invertor has = $800
To find:
The inequality that can be solved to show the number of shares s he can buy.
Solution:
Let x be the number of shares he can buy.
Price of 1 share = $3.75
Price of x shares = $3.75x
An investor has $800.
The price of x shares must be less than or equal to the amount he has. So,
[tex]3.75x\leq 800[/tex]
Divide both sides by 3.75.
[tex]x\leq \dfrac{800}{3.75}[/tex]
[tex]x\leq 213.33...[/tex]
So, the maximum possible integer value of x is 213.
Therefore, the equation inequality is [tex]3.75x\leq 800[/tex] and he can buy 213 shares.

F(x) = 5x⁴ for 0<x<1 and 0 otherwise
f(y)= 2y³ +y for 0<y<1 and 0 otherwise
the joint p.d.f is given by
f(x,y) = f(x) * f(y)= 5x⁴(2y³ +y ) 0<x<1 , 0<y<1 , 0 otherwise
The joint pdf is found by multiplying the marginal pdfs.
The two random variables are said to be statistically independent if the joint probability function can be expressed as the product of two marginal functions.

A normally distributed population has a mean of 500 and a standard deviation of 60. Determine the probability that a random sample of size 16 selected from this population will have a sample mean less than 475. A. 0.3251 B. 0.0712 C. 0.7124 D. 0.0475
Answers
Answer:
D
Step-by-step explanation:
We start out by calculating the z-score
z = (x-mean)/SD/√n
x = 475
mean = 500
SD = 60
n = 16
Substituting these;
z = (475-500)/60/√16
z = (-25)/60/4
z = -25/15
z = -1.67
So the probability we want to
calculate is P (x < -1.67)
we can use the standard normal distribution table here;
And from the standard normal distribution table;
we have P( x < -1.67) as 0.04746
which is approximately 0.0475
The probability that this population will have a sample mean less than 475 is 0.0475
z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } \\\\where\ \mu=mean,\sigma=standard\ deviation,x=raw\ score,n=sample\ size[/tex]
Given that n = 16, μ = 500, σ = 60.
For x < 475:
[tex]z=\frac{475-500}{60/\sqrt{16} } =-1.67[/tex]
From the normal distribution table, P(x < 475) = P(z < -1.67) = 0.0475
The probability that this population will have a sample mean less than 475 is 0.0475
