If cot x = -4/3 find csc x, if 270°<x<360"
Answer:
csc x = - [tex]\frac{5}{3}[/tex]
Step-by-step explanation:
Using the trigonometric identity
csc²x = 1 + cot²x
= 1 + (- [tex]\frac{4}{3}[/tex] )² = 1 + [tex]\frac{16}{9}[/tex] = [tex]\frac{25}{9}[/tex], thus
csc x = ± [tex]\sqrt{\frac{25}{9} }[/tex] = ± [tex]\frac{5}{3}[/tex]
Since 270° < x < 360° where csc x < 0 , then
csc x = - [tex]\frac{5}{3}[/tex]

E) Calculate the residuals for your scatterplot in step 2d (image attached below)
F) create a residual plot for your data
I’LL VOTE 5 STARS TOO!
Answer:
In the simplest meaning, you have:
Residual (e) = Observed value (y) - Predicted value (y')
Here, observed value y has been provided in table.
The predict value y' is calculated based on the linear regression model shown in your picture: y = 0.161x + 0.748, by substitute x into this model, you obtain the predict value y'.
x = 1.11, 18, 21.9, 18, 16.7, 20, 15.5, 19.5
=> Corresponding y' would be:
y' = 0.93, 3.65, 4.27, 3.65, 3.44, 3.97, 3.24, 3.89
From the table, you have corresponding observed value y:
y = 0.7, 4, 3.69, 3.8, 3.21, 4, 3.92, 3.77
=> Subtract y to y', you obtain the corresponding residual e:
e = -0.23, 0.35, -0.58, 0.15, -0.23, 0.03, -0.68, -0.12
Plot vector e on y axis, and vector x on x-axis respectively, you got the residual plot
Hope this helps!
:)
Answer:
E) -0.23, 0.35, -0.58, 0.15, -0.23, 0.03, -0.68, -0.12
F) on the horizontal axis, take the x values and on the vertical axis, take residuals
Step-by-step explanation:
Given:
y = 0.7, 4, 3.69, 3.8, 3.21, 4, 3.92, 3.77
Using the regression equation:
y' = 0.93, 3.65, 4.27, 3.65, 3.44, 3.97, 3.24, 3.89
Residuals: y - y'
-0.23, 0.35, -0.58, 0.15, -0.23, 0.03, -0.68, -0.12

Find the 14th term of the geometric sequence 1 , − 5 , 25 , . . .
Answer:
-1220703125
Explanation:
The 14th term of the geometric sequence 1 , − 5 , 25 , . . . is (5)¹⁴ after using the geometric sequence formula.
What is a sequence?It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.
It is given that:
The sequence is:
1 , − 5 , 25 , . . .
The above sequence represents a geometric sequence.
Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity,
approaching either infinity or -infinity.
The common ratio = -5/1 = -5
The nth term a(n) = arⁿ⁻¹
The first term a = 1
The nth term a(n) = (5)ⁿ⁻¹
Plug n = 14
The 14th term a(14) = (-5)¹⁵⁻¹
The 14th term a(14) = (5)¹⁴
Thus, the 14th term of the geometric sequence 1 , − 5 , 25 , . . . is (5)¹⁴ after using the geometric sequence formula.

HOW MANY FEET GREATER IS THE CIRCUMFERENCE OF THE OUTER CIRCLE THAN IT IS OF THE THE INNER CIRCLE *ROUND TO THE NEAREST TENTH*
answer fast please!
Answer:
25.1
Step-by-step explanation:
1. Find the radius of the inner circle
(the formula for the circumference of a circle is [tex]C=2\pi r[/tex])
To find the radius of the inner circle, you would plug in the given information so that your equation looks like this:
[tex]22=2(\frac{22}{7} )r[/tex]
then solve for [tex]r[/tex]
[tex]r=3.5[/tex]
2. add [tex]4[/tex] to the radius of the inner circle
[tex]3.5+4=7.5[/tex]
3. find the circumference of the outer circle using [tex]7.5[/tex] as the radius
[tex]C=2(\frac{22}{7})7.5[/tex]
[tex]C=47.1[/tex]
4. Subtract the circumference of the inner circle from the circumference of the outer circle
[tex]47.1-22=25.1[/tex]

Given:
m∠QPS=107∘
m∠RPS=4x+27∘
m∠QPR=9x-115∘
Find m∠QPR
**This was on Khan Academy, so please hurry lol**
Answer:
m∠QPR = 20°
Step-by-step explanation:
If we make a sketch of the triangle, it will be observed, that line R bisects angle P.
Considering Triangle, ΔQPS;
∠QPS=107∘
Considering triangle, QPR;
∠QPR=9x-115∘
Considering triangle, RPS;
∠RPS=4x+27∘
Thus, ∠RPS + ∠QPR = ∠QPS
4x+27° + 9x-115° = 107°
13x - 88° = 107∘
13 x = 107∘ + 88∘
13x = 195°
x = 195°/13
x = 15°
m∠QPR = 9x - 115°
= (9 x 15) - 115°
= 135° - 115°
= 20°
Therefore, m∠QPR = 20°
The average age of people attending a concert was 23 years old, with a standard deviation of 7. What percentage of people at the concert were older than 37 years old?
Answer:
2.28%
Step-by-step explanation:
We have that the mean (m) equals 23 and that the standard deviation (sd) is 7.
We can calculate the value z and in this way we can calculate the probability in this case with the calculation of the normal distribution table:
z = m - x / sd
we know that x is 37, replacing:
z = (23 - 37) / 7
z = -2
according to the normal distribution table the value of z = -2, is equivalent to 0.0228
So the probability is 2.28%

What is the volume in cubic feet rounded to the
nearest whole foot of the figure?
Answer:
Volume Con = pi x radius^2 x h/3
Volume Sphere = 4/3 x pi x radius^3
Step-by-step explanation:
Volume of shape = Volume of Cone + 1/2 x Volume of Sphere
Volume of shape = pi x radius^2 x h/3 +1/2 (4/3 x pi x radius^3)
Volume = (3.14 x 39^2 x (81-39)/3) + 1/2(4/3 x 3.14 x 39^3)
Volume = (3.14 x 1521 x 14) + 1/2 (4/3 x 3.14 x 59319)
Volume = (66863.2) + (124174.4)
Volume = 191037.6
Volume = 191038 cubic ft

Submit
Mark this and retum
Answer:
The representative sample contained more girls than boys.
Step-by-step explanation:
A "sample" of something is a small part of it. A "representative sample" is a small part of the students that represents them all. A random sample would not include all 160 students. It is more likely that there would be more girls than boys, than more boys than girls. In total, there are more girls than boys: 95 girls to 65 boys. It is more likely that a sample of the total students would be just like the total, but smaller.

A triangle has a leg with a length of 3 and a hypotenuse with a length of 6.What is the length of the other leg?
Answer:
3[tex]\sqrt{3}[/tex]
Step-by-step explanation:
Using Pythagoras' identity on the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the length of the other leg, then
x² + 3² = 6², that is
x² + 9 = 36 ( subtract 9 from both sides )
x² = 27 ( take the square root of both sides )
x = [tex]\sqrt{27}[/tex] = [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex] ← exact value

PLEASE IM STUGGLING
Answer:
in the step by step
Step-by-step explanation:
1-I could tell by matching the width of the rectangle with the circumference of the lid. The width would wrap perfectly around the circle if it is the same length at the circumference.
2-The width would be different because the width is equal to the circumference.
3-First, I would find the circumference. I would do 2(h)*pi to find the circumference. I would draw two circles with this circumfrence, then I would put a rectangle in between the circles with the height as the height of the cylinder and the width as the circumference.
What is the slope of y= 5x-1
Answer:
5
Step-by-step explanation:
The first number before the x is the slope which is the quotient of the rise and the run of the line. The number after the x is where the line intercepts the y axis which is called the y intercept.
Answer:
m= 5
Step-by-step explanation:
The line is in slope-intercept form
y=mx+b
where m is the slope and b is the y-intercept
We have the line:
y=5x-1
5 is the coefficient that comes before x, therefore 5 is the slope.
The constant being subtracted, -1, is the y-intercept
Therefore: m=5 and b=-1
The slope is 5

(A)James is correct.There are fewer rows, so there will be more in each row. There will be 12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.
Step-by-step explanation:
James is putting 24 jelly beans into equal rows.
If he puts the jelly beans in 2 equal rows:
Number in each row=24/2=12 jelly beans per row.
If he puts the jelly beans in 3 equal rows:
Number in each row=24/3=8 jelly beans per row.
Therefore, James is correct.There are fewer rows, so there will be more in each row. There will be 12 jelly beans in each row for 2 equal rows, and 8 jelly beans in each row for 3 equal rows.
The correct option is A.
