Hi there.
4th quadrant.Recall that:
csc θ = 1 / (sin θ) - deals with y-values
sec θ = 1 / (cos θ) - deals with x-values
If csc θ < 0, then the y-coordinate of the angle must be negative.
If sec θ > 0, then the x-coordinate of the angle must be positive.
The quadrant on the coordinate plane that consists of negative y-coordinates and positive x-coordinates is the 4th quadrant.
Answer:
QIV
Step-by-step explanation:
To answer this question, we can use the standard ASTC acronym.
This stands for: All Students Take Calculus.
The first letter of each word tells us what is positive in each quadrant.
So, in QI, all trig ratios are positive.
In QII, only sine ( and cosecant) is positive.
In QIII, only tangent (and cotangent) is positive.
And in QIV, only cosine (and secant) is positive.
We know that csc(θ)<0. In other words, csc(θ) is negative.
Since csc(θ) is negative, sin(θ) is also negative.
So, our θ can't be in QI or QII.
We also know that sec(θ) is positive.
Our θ can only either be in QIII or QIV.
In QIII, only tangent is positive, so cosine will be negative.
So, θ is not in QIII.
So, the only choice that remains is QIV. And cosine and secant are indeed positive in QIV.
So, our angle θ is in QIV.
And we're done!

The average distance of Mercury from the Sun is 36 million miles. The distance varies by 7.5 million miles.
Use this information to complete this statement.
The minimum distance of Mercury from the Sun is ___ million miles, and the maximum distance is ___ million miles.
Answer:
The minimum distance of Mercury from the Sun is
28.5
million miles, and the maximum distance is
43.5
million miles.
Step-by-step explanation:
its the right answer
you add or subtract 7.5 from 36 to get the minimum and maximum because thats the distance from 36 that it varies
Answer:
#1. 28.5
#2. 43.5

Step-by-step explanation:
(a) Find the average and SD of the list 41, 48, 50, 50, 54, 57.
(b) Which numbers on the list are within 0.5 SDs of average? within 1.5 SDs of average? 2.
(a) Both of the following lists have the same average of 50. Which one has the smaller SD, and why? No computations are necessary. (i) 50, 40, 60, 30, 70, 25, 75 (ii) 50, 40, 60, 30, 70, 25, 75, 50, 50, 50
(b) Repeat, for the following two lists. (i) 50, 40, 60, 30, 70, 25, 75 (ii) 50, 40, 60, 30, 70, 25, 75, 99, 1
Answer:
1a) Mean = 40
Standard Deviation = 5
b)i Which numbers on the list are within 0.5 SDs of average?
48, 50, 50
ii) within 1.5 SDs of average?
48, 50, 50, 54, 57
2a)Both of the following lists have the same average of 50. Which one has the smaller SD, and why? No computations are necessary.
The list with the smaller S.D = (ii) 50, 40, 60, 30, 70, 25, 75, 50, 50, 50
This because the results obtained from the second list (ii) is close to the mean , therefore, the Standard deviation is small.
b) Repeat, for the following two lists.
The list with the smaller S.D = (i) 50, 40, 60, 30, 70, 25, 75
This because the results obtained from the second list (i) is close to the mean , therefore, the Standard deviation is small.
Step-by-step explanation:
1a) Find the average and SD of the list 41, 48, 50, 50, 54, 57.
Average (Mean) = Sum of terms/Number of terms
= 41+ 48 + 50 + 50+ 54 + 57/6
= 300/6
= 50
Standard Deviation for the population= √(x - Mean)²/n
=√ (41 - 50)²+ (48- 50)² + (50- 50)² +(50- 50)² + (54 - 50)² +(57- 50)²/6
= √81 + 4 + 0 + 0 + 16 + 49/6
= √150/6
= √25
= 5
(b) Which numbers on the list are within 0.5 SDs of average?
Mean ± Standard deviation × 0.5
50 ± 5 × 0.5
50 - 2.5
= 47.5
50 + 2.5
= 52.5
The numbers on the list are within 0.5 SDs of average are number within 47.5 and 52.5 : 48, 50, 50
ii) Within 1.5 SDs of average?
Mean ± Standard deviation × 1.5
50 ± 5 × 1.5
50 - 7.5
= 42.5
50 + 7.5
= 57.5
The numbers on the list are within 1.5 SDs of average are numbers within 42.5 and 57.5: 48, 50, 50, 54, 57
2 (a) Both of the following lists have the same average of 50. Which one has the smaller SD, and why? No computations are necessary.
(i) 50, 40, 60, 30, 70, 25, 75
Mean is already give as 50
Standard Deviation = √(x - mean)²/n
= √(50 - 50) + (40- 50)² (60 -50)² +(30- 50)² + (70 - 50)² + (25 - 50)² (75 - 50)² /n
= √0 + 100 + 100 + 400+ 400 + 625 + 625/7
= √2250/7
= √321.4285714
= 17.92842914
(ii) 50, 40, 60, 30, 70, 25, 75, 50, 50, 50
Standard deviation = √(x - mean)²/n
√(50 -50)²+(40-50)² + (60 -50)²+ (30-50)² + (70 - 50)²+ (25-50)² +(75-50)² + (50 -50)² + (50 - 50)²+(50 - 50)²/10
= √0 + 100 + 100 + 400 + 400 + 625 + 625 + 0 + 0 + 0/10
√2250/10
√225
= √15
The list with the smaller S.D = Second list (ii) 50, 40, 60, 30, 70, 25, 75, 50, 50, 50
This because the results obtained from the second list (ii) is close to the mean , therefore, the Standard deviation is small.
(b) Repeat, for the following two lists.
(i) 50, 40, 60, 30, 70, 25, 75
Mean is already give as 50
Standard Deviation = √(x - mean)²/n
= √(50 - 50) + (40- 50)² (60 -50)² +(30- 50)² + (70 - 50)² + (25 - 50)² (75 - 50)² /n
= √0 + 100 + 100 + 400+ 400 + 625 + 625/7
= √2250/7
= √321.4285714
= 17.92842914
(ii) 50, 40, 60, 30, 70, 25, 75, 99, 1
Standard Deviation = √(x - mean)²/n
= √(50-50)² +( 40 -50)² +( 60 - 50)² + (30 - 50)²+( 70 - 50)² + (25 - 50)² + (75 - 50)² +(99 - 50)² +(1 -50)²/9
= √0 + 100 + 100 + 400 + 400+ 625 + 625 + 2401 +2401/9
= √7052/9
= √783.5555556
= 27.99206237
The list with the smaller S.D = (i) 50, 40, 60, 30, 70, 25, 75
This because the results obtained from the first list(i) is close to the mean , therefore, the Standard deviation is small.

Mario has to buy oranges at the grocery store. Oranges cost $1.15 per pound.
How much will Maria spend on oranges?
Dependent variable:
Independent variable:
Equation:
Answer:
Dependent variable: Amount of oranges ([tex]y[/tex]), measured in pounds.
Independent variable: Money ([tex]x[/tex]), measured in US dollars.
Equation: [tex]y = 1.15\cdot x[/tex]
Step-by-step explanation:
According to the statement, Maria pays money to buy oranges at the grocery and there is a direct proportionality between money ([tex]x[/tex]), measured in US dollars, and the amount of oranges ([tex]y[/tex]), measured in pounds. That is:
[tex]y \propto x[/tex]
[tex]y = k\cdot x[/tex]
Where [tex]k[/tex] is the proportionality constant, measured in US dollars per pound.
The dependent variable is the amount of oranges ([tex]y[/tex]), whereas money ([tex]x[/tex]) represents the independent variable. If we know that [tex]k = 1.15\,\frac{USD}{pd}[/tex], then the equation is:
[tex]y = 1.15\cdot x[/tex]
In a nutshell, the answer is:
Dependent variable: Amount of oranges ([tex]y[/tex]), measured in pounds.
Independent variable: Money ([tex]x[/tex]), measured in US dollars.
Equation: [tex]y = 1.15\cdot x[/tex]
c-x=d-d-r-cr solve for x how do i get the x alone? all these problems i have leave it as -x=
Answer:
x= r+cr+c
Step-by-step explanation:
Statement l Reason
----------------------------------------------------------------------------------------------------------------
c-x= d-d-r-cr l Given
----------------------------------------------------------------------------------------------------------------
-x= d-d-r-cr-c l Subtraction: First you need to subtract c from both sides
----------------------------------------------------------------------------------------------------------------
-x= -r-cr-c l Combine like terms
----------------------------------------------------------------------------------------------------------------
x= r+cr+c l Divide: You need to divide by negative one on both sides

Answer:
Part A)
[tex]86=2(x+22)[/tex]
Part B)
[tex]l=26\text{ cm}[/tex]
Step-by-step explanation:
We know that the rectangle has a length of (x+5) and a width of 12 cm.
Part A)
Remember the formula for the perimeter of a rectangle:
[tex]P=2(l+w)[/tex]
We know that the perimeter is 86. Substitute that for P:
[tex]86=2(l+w)[/tex]
Substitute (x+5) for the length l and 17 for w. So:
[tex]86=2((x+5)+17)[/tex]
We can simplify this to acquire our equation:
[tex]86=2(x+22)[/tex]
Part B)
To find the length, let's find our x first. We have the equation:
[tex]86=2(x+22)[/tex]
Divide both sides by 2:
[tex]43=x+22[/tex]
Now, subtract 22 from both sides. Therefore, our x is:
[tex]x=21[/tex]
To find the length, remember that the length is:
[tex]l=x+5[/tex]
Since we now know the value of x, substitute 21 for x:
[tex]l=21+5[/tex]
Add:
[tex]l=26\text{ cm}[/tex]
So, the length is 26 centimeters.
And we're done!
