The Positive Z-Equal Line, the Negative Z-Equal Line, and the Regression Line all pass through the same point. What are the standardized coordinates of this point
Answer:
The standard coordinates of the point are ; ( 0,0 )
Step-by-step explanation:
The standard coordinates of the point are ; ( 0,0 ) also the standard values of the means will also be ( 0, 0 )
This is because for the Positive Z-equal line, Negative Z-Equal line and Regression line to all pass through the same point indicates dependent and independent variables of the Z-score and regression lines respectively

The perimeter of a rectangle is 162 inches. what are the dimensions of the rectangle if the length is 7 times than 3 times the width?
Answer:
3.68 inches × 77.28 inches
Step-by-step explanation:
Given that,
The perimeter of a rectangle is 162 inches.
Let the width is b.
ATQ,
Length = 7 times than 3 times the width
l = 7(3b) = 21b ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
Put all the values,
162 = 2(21b+b)
81 = 22b
b = 3.68 inches
Put the value of b in equation (1)
l = 21b
= 21 (3.68)
= 77.28 inches
Hence, the dimensions of the rectangle are 3.68 inches × 77.28 inches

Of the 140 7th graders, 15% earn the Presidential Physical Fitness award. How many students earn the award? *
Answer:
21 students
Step-by-step explanation:
the percent proportion is a/w = p/100
where A is a part of the whole W, and p% or p/100 is the percent
a/140 = 15/100 (Substitute w =140 and p= 15)
a times 100=140 times 15 (cross poducts property)
100a=2100 (Multiply)
100a/100 = 2100/100 (divide both sides by 100)
a = 21 (simplify)
So, 21 students win the award.
Which formula gives the x-coordinates of the maximum values for y= cos()?
O kr for any integer k
Okr for k= 0,+2,t4
O7for any positive integer k
o
for K= 0,+2,+4,
Answer:
option b
Step-by-step explanation:
just trust
The formula that gives the x-coordinates of the maximum values of
y = cos(x) is kπ for k= 0, 2±, ±4.
Option B is the correct answer.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
The formula that gives the x-coordinates of the maximum values for
y = cos(x) is kπ + π/2 or (2k+1)π/2, where k is any integer.
Now,
This formula corresponds to kπ for k= 0, 2±, ±4
where k can take the values 0, 2, -2, 4, -4, etc.
The cosine function oscillates between -1 and 1, with a period of 2π.
The maximum value of the function is 1, which occurs when the argument of the cosine function is an odd multiple of π/2.
This means that the x-coordinates of the maximum values are given by:
x = kπ + π/2, where k is any odd integer
We can simplify this formula by writing k = 2m+1, where m is any integer, to obtain:
x = (2m+1)π/2
This formula covers all the possible values of k, including positive and negative integers.
For example, when m = 0, we get x = π/2, which is the first maximum value of the function.
When m = 1, we get x = 3π/2, which is the second maximum value, and so on. If we allow m to be negative, we get the values of x for the maximum values of the cosine function in the negative direction.
Therefore,
kπ for k= 0, 2±, ±4
which gives the values of k that correspond to the x-coordinates of the maximum values of y = cos(x).

Step-by-step explanation:
we know something about the angles of a triangle already
A + B + C = 180°
soooo...
X + X + (X+30)= 180

Matthew purchased a desk that was on sale for 45% off the orginal price of $480.If the sales tax was 8% (of the sale price), how much did mattew spend on the desk
Answer:
285.12
Step-by-step explanation:
discount amount = 45/100 x 480= 45x48/10
=216.0
price after discount= 480-216=264
sales tax= 8/100 x 264=21.12
total money spent = 264+21.12=285.12
45% of 480
= 45/100 x 480
= 0.45x480
=216
=480-216
=264
8% of 264
= 8/100 x 264
= 0.08 x 264
= 21.12
= 264 + 21.12
=285.12
Therefore, he paid $285 and 12 cents

You deposit $300 in a savings account that pays 6% interest compounded semiannually. How much will you have at the middle of the first year? How much at the end of one year?
Answer:
The total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 0.5 years is $ 309.00. The total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 1 year is $ 318.27.Step-by-step explanation:
a) How much will you have at the middle of the first year?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
where
Principle = PAnnual rate = rCompound = nTime = (t in years) A = Total amountGiven:
Principle P = $300
Annual rate r = 6% = 0.06 per year
Compound n = Semi-Annually = 2
Time (t in years) = 0.5 years
To determine:
Total amount = A = ?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
substituting the values
[tex]A=300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(0.5\right)}[/tex]
[tex]A=300\cdot \frac{2.06}{2}[/tex]
[tex]A=\frac{618}{2}[/tex]
[tex]A=309[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 0.5 years is $ 309.00.
Part b) How much at the end of one year?
Using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
where
Principle = PAnnual rate = rCompound = nTime = (t in years) A = Total amountGiven:
Principle P = $300
Annual rate r = 6% = 0.06 per year
Compound n = Semi-Annually = 2
Time (t in years) = 1 years
To determine:
Total amount = A = ?
so using the formula
[tex]A\:=\:P\left(1+\frac{r}{n}\right)^{nt}[/tex]
so substituting the values
[tex]A\:=\:300\left(1+\frac{0.06}{2}\right)^{\left(2\right)\left(1\right)}[/tex]
[tex]A=300\cdot \frac{2.06^2}{2^2}[/tex]
[tex]A=318.27[/tex] $
Therefore, the total amount accrued, principal plus interest, from compound interest on an original principal of $ 300.00 at a rate of 6% per year compounded 2 times per year over 1 year is $ 318.27.

The lengths of a professor's classes has a continuous uniform distribution between 60.0 min and 90.0 minutes. If one such class is randomly selected, find the probability that the class length is less than 76 min.
Answer:
0.533
Step-by-step explanation:
Given that :
Class length has a Continuous uniform distribution between 60 - 90 min
Lower limit (L1) = 60
Upper limit (L2) = 90
Probability that class length is less than 76 min
P(x < 76):
(x - L1) / (L2 - L1)
(76 - 60) / (90 - 60)
16 / 30
= 0.533
P(x < 76) = 0.533
