At times, latitudes with values higher than ________ degrees can have ~ 24 hours of continuous sunshine.
At times, latitudes with values higher than 66.5 degrees can have ~ 24 hours of continuous sunshine.
Locations above the Arctic Circle (north of latitude 66.5 degrees, 90 degrees minus the tilt of the Earth's axis) are exposed to 24-hour sunlight. Below the Arctic Circle (latitude 66.5 degrees south), there is 24-hour darkness.
When at the equator, the sun is directly above – at the poles, the sun is on the horizon. However, regardless of the current location (from the pole to the equator), all parallels are bisected, so we have 12 hours a day and 12 hours a night in all locations.

What is a Right Angled Triangle ?A right angled triangle is a triangle that has one of its angle measure as 90 degree.
It is given that
Ladder Length = 22 foot
The angle between the ladder and the ground is 65 degree.
When the ladder leans on a wall , the wall makes 90 degree with the ground and the ladder is the hypotenuse of the right angled triangle formed.
The figure is attached with the answer.
sin 65 = Height of the wall / Hypotenuse

Question: 7 After seven years, the age of father will be 4 times the age of his daughter. If x stands for the present age of the daughter and y stands for the present age of the father, which of th following linear equations represents the above statement?
x+y-17=0
2xy-187=0
x+y+17=0
2xy+187=0
Answer:
Here is your answer
Step-by-step explanation:
Step -1: Forming equations.
Let, present age of son = x
And, present age of father = 3x+3
3 years later, age of son = x+3
age of father = 3x+3+3=3x+6 ...(i)
According to the given condition, age of father = 10+2(x+3) ...(ii)
Step -2: Solving for x
From (i) and (ii)
∴3x+6=10+2(x+3)
⇒3x+6=10+2x+6
⇒3x−2x=10+6−6
⇒x=10
∴Present age of son = 10
and present age of father = 3x+3=3×10+3=33
Hence, son’s present age is 10 years and father’s

Suppose a large shipment of laser printers contained 12% defectives. If a sample of size 406 is selected, what is the probability that the sample proportion will be greater than 13%
The probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.
According to the Central limit theorem, if from an unknown population large samples of sizes n > 30, are selected and the sample proportion for each sample is computed then the sampling distribution of sample proportion follows a Normal distribution.
The mean of this sampling distribution of sample proportion is:
цр = р
The standard deviation of this sampling distribution of sample proportion is:
бр = √ρ(1-ρ)÷n
The information provided is:
ρ = 0.22
ⁿ = 276
As the sample size is large, i.e. n = 276 > 30, the Central limit theorem can be used to approximate the sampling distribution of sample proportion.
Compute the value of P(р-p<0.06) as follows:
P(р-p<0.06) = P(р-p ÷ бp<0.06 ÷√0.22(1 - 0.22) ÷ 276
= P ( Z < 2.41 )
= 0.99202
≈ 0.992
Thus, the probability that the sample proportion will differ from the population proportion by less than 6% is 0.992.

The population of a small industrial town was 12 910 in 2000. Each year, the population
decreases by an average of 5%. Estimate the population in the year 2020. Round to the nearestwhole number.
The population in the year 2020 is 4628
How to determine the population?The given parameters are:
Initial, a = 12910
Rate, r = 5%
Since the population decreases, then we make use of an exponential decay function.
This is represented as:
f(n) = a * (1 - r)^n
So, we have:
f(n) = 12910 * (1 - 5%)^n
Evaluate the difference
f(n) = 12910 * 0.95^n
2020 is 20 years from 2000.
So, we have:
f(20) = 12910 * 0.95^20
Evaluate
f(20) = 4628
Hence, the population in the year 2020 is 4628

Step-by-step explanation for each question:
For Question 6, the range of a function is all the possible outputs of the function. Since the function can only take the inputs 0, 4, and 7, we can just plug in each into the formula and find their corresponding outputs.
g(0) = 0² - 9 = 0 - 9 = -9
g(4) = 4² - 9 = 16 - 9 = 7
g(7) = 7² - 9 = 49 - 9 = 40
Therefore the only possible outputs of function g, or the range, is {-9, 7, 40}.
For question 4, the input t is a given time, and h(t) is the height of the football at that time.
Hence, h(2.5) is the height of the football (in feet) at 2.5 seconds. The value 2.5 can be plugged into the function [tex]-16t^2+58t+2[/tex] to get the height. This gives us
[tex]-16(2.5)^2 + 58(2.5) + 2[/tex]
[tex]-16(6.25) + 58(2.5) + 2[/tex] [Squaring 2.5]
[tex]-100 + 145 + 2[/tex] [Multiplying]
[tex]47[/tex] [Combining all terms]
We find that the height of the football at 2.5 seconds is 47 feet.
For Question 5, the table of values show all the possible values x can be (or the domain), and what the output of the function f(x) would give for each.
A) f(-3) = 5, as the row with -3 for x has -5 for y.
B) f(0) = 0, as the row with 0 for x has 0 for y.
C) f(1) = -3, as the row with 1 for x has -3 for y.
The range of the function will be -9,7 and 40.
What is the difference between domain and range?The domain denotes all potential x values, while the range denotes all possible y values.
Given equation;
g(x) = x²-9
The range of the given domain is found by putting the values one by one in the above equation as;
g(x) = x²-9
a)For x = 0
g(x) = 0²-9
g(x) =-9
b)For x =4
g(x) = 4²-9
g(x) =16-9
g(x) = 7
c)For x =7
g(x) = 7²-9
g(x) =49-9
g(x) = 40
Hence, the range of the function will be -9,7 and 40.

Each of the performers at a circus convention is either a unicyclist, a mime or an aerial artist. The ratio of unicyclists to mimes is 3: 14 The ratio of unicyclists to aerial artists is 9 : 11 There are 88 aerial artists. What percentage of the performers are unicyclists? Give your answer to 2 d.p.
Answer:
14.52% are unicyclists
Step-by-step explanation:
First, we can use proportions to find the number of unicyclists at the convention. Since we know that the ratio of unicyclists to aerial artists is 9:11, and there are 88 aerial artists, we can set up the following equation:
[tex]\frac{9}{11}=\frac{x}{88}[/tex]
If we cross multiply, we get that 11x = (88)(9). After we divide through by 11 to isolate x, we get that x = (8)(9) = 72
Second, we have to figure out the number of mimes at the convention to figure out the total number of people there. We know that the ratio of unicyclists to mimes is 3:14, and the number of unicyclists is 72. So, we can set up the following proportion:
[tex]\frac{3}{14}=\frac{72}{y}[/tex]
If we cross multiply, we get that 3y = 1008, or y = 336 mimes
The total number of people at the convention is 336 mimes + 72 unicyclists + 88 unicyclists = 496. Now we have to figure out what percent of 496 is 72 (the number of unicyclists). If we let z = the percentage, we can simply set up an equation that says that 72 is z% of 496:
[tex]72=0.01z*496\\0.01z=0.14516\\z=14.52[/tex]
This means that approximately 14.52% of the performers are unicyclists.
Answer:
14.52%
Step-by-step explanation:
U/A = 9/11 and A = 88 multiply by 8/8 ( to get A=88 as given)
9/11 * 8/8 = 72/88 = U / A so U = 72
Then U/M = 3/14 multiply by 24/24 ( to get U = 72 as found above)
then U/M= 72 / 336 M = 336
U / ( A + U + M ) x 100% = 14.52 %

There is a profit of $39.7.
It is given that there 100 tickets costing $10 per ticket.
You must look first for the probability of the 4 prizes which are $475, $195, $30, and no prize.
P ($475 prize) = 1/100 or 0.01
P ($95 prize) = 2/100 or 0.02

Angles EBA and DBC are congruent. The three angles EBA, EBD, and DBC are together supplementary, so their measures sum to 180°. This means
x + (4x + 11°) + x = 180°
6x + 11° = 180°
6x = 169°
x = (169/6)°
Then the measure of angle D is
2x + 8° = 2 (169/6)° + 8° = (193/3)°
The interior angles of any triangle sum to 180°, so if y is the measure of angle C, we have
(169/6)° + (193/3)° + y = 180°
y = (175/2)° = 87.5°

consider substituting [tex]y=x^{-2}[/tex] to get a proper quadratic equation,
[tex]25y^2 - 99y - 4 = 0[/tex]
Solve for [tex]y[/tex] ; we can factorize to get
[tex](25y + 1) (y - 4) = 0[/tex]
[tex]25y+1 = 0 \text{ or } y - 4 = 0[/tex]
[tex]y = -\dfrac1{25} \text{ or }y = 4[/tex]
Solve for [tex]x[/tex] :
[tex]x^{-2} = -\dfrac1{25} \text{ or }x^{-2} = 4[/tex]
The first equation has no real solution, since [tex]x^{-2} = \frac1{x^2} > 0[/tex] for all non-zero [tex]x[/tex]. Proceeding with the second equation, we get
[tex]x^{-2} = 4 \implies x^2 = \dfrac14 \implies x = \pm\sqrt{\dfrac14} = \boxed{\pm \dfrac12}[/tex]
If we want to find all complex solutions, we take [tex]i=\sqrt{-1}[/tex] so that the first equation above would have led us to
