Step-by-step explanation:
using Pythagoras' identity in the right triangle formed by the radius 1 and the given point, then
y² + (- [tex]\frac{17}{20}[/tex] )² = 1²
y² + [tex]\frac{289}{400}[/tex] = 1
y² = 1 - [tex]\frac{289}{400}[/tex] = [tex]\frac{111}{400}[/tex] ( take square root of both sides )
y = ± [tex]\sqrt{\frac{111}{400} }[/tex] = ± [tex]\frac{\sqrt{111} }{20}[/tex]

Answers
The expression to illustrate the information when Maria bought the tickets is C = (5 × $20) + ($2 × 5) and the total amount paid is $110.
How to illustrate the information?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. A mathematical expression shows the value of something by combining numbers, variables, and operators. It's possible to multiply, divide, add, or subtract with this mathematical operation.
Mathematical operators like addition, subtraction, multiplication, and division are used to create expressions in writing. For instance, the mathematical equation for "4 added to 2" will be 2+4.
From the information, Maria bought 5 tickets for $20 each. Each ticket had a $2 fee.
The expression that can be used to illustrate this will be:
C = (5 × $20) + ($2 × 5)
where C = Total cost
C = $100 + $10
C = $110
Therefore the expression to illustrate the information when Maria bought the tickets is C = (5 × $20) + ($2 × 5) and the total amount paid is $110.

In a survey on internet usage , it was found that out of a total of 27 people, 16 use ADSL lines, 15 use wireless internet and 3 use neither of the two . what is the probability that a person chosen at random uses both internet connections
Answers
The probability that a person chosen at random uses both internet connections is 1/9
Total number of people = 27
Number of people who use ADSL lines = 16
Number of people who use wireless internet = 15
Number of people who use neither of the two = 3
Let the number of people who use only ADSL lines and wireless internet be denoted by A and B respectively.
Then A + B + A∩B + 3 must be equal to 27
A + B + A∩B = 24
further, we can see that
(A + A∩B) = 16
B + 16 = 24
B = 8
Also, (B + A∩B) = 15
8+ A∩B = 15
A∩B = 7
Thus, the number of people who use both internet connections = 7
Now, P(A∩B) = 7/27
= 1/9
Hence, probability that a person chosen at random uses both internet connections is 1/9.

Let's go through the four answer choices to see which are true and which are false. We'll rule out the ones that are true.
A) This is true. We can use inductive reasoning to form a conjecture. A conjecture is basically a generalized guess. For example, a guess would be something like "the sum of the first n odd numbers is n^2". So 1+3 = 4, 1+3+5 = 9, 1+3+5+7 = 16, 1+3+5+7+9 = 25, and so on. Does the pattern go on forever? Or does it stop at some point? That's why a proof is needed.B) This is true. See choice A.C) This is true. Some conjectures have been proven (such as the example I mentioned in choice A) while others have not. A famous unproven conjecture is Goldbach's Conjecture. D) This is false. Inductive reasoning helps form a conjecture, but it does not lead to definitive proof. We would need deductive reasoning.Lorie ordered a shed to hold her gardening supplies.

The volume of the shed ordered by Lorie to hold her gardening supplies is (option a) 1423.5 cubic ft.
Given,
Lorie ordered a shed to hold her gardening supplies.
The length of the shed, l = 18.25 feet
The width of the shed, w = 15 feet
The height of the shed, h = 5 1/5 feet = 26/5 = 5.2 feet
We have to determine the volume of the shed:
From the given data we can assume that the shed is like a cuboid. So to determine the volume, we can use the cuboidal formula.
That is,
Volume = length × width × height
V = l × w × h
V = 18.25 × 15 × 5.2
V = 1423.5 feet
Therefore, the volume of the shed ordered by Lorie to hold her gardening supplies is 1423.5 feet.

the probability that the student is both a freshman and a mathematics major is 3/17. given that the student selected is a freshman, what is the probability that he is also a mathematics major is 3/10.Definition of ProbabitityProbability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.
The probability of any event A is defined as the ratio between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
P(A)= number of favorable cases÷ number of total cases
Union of eventsThe union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".
The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:
P(A∪B)= P(A) + P(B) -P(A∩B)
The intersection of events, A∩B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.
Complementary eventA complementary event, also called an opposite event, is made up of the inverse of the results of another event.
The probability of occurrence of the complementary event A' will be 1 minus the probability of occurrence of A:
P(A´)= 1- P(A)
Conditional probabilityThe conditional probability P(A|B) is the probability that an event A occurs, knowing that another event B also occurs. That is, it is the probability that event A occurs if event B has occurred. It is defined as:
P(A|B) = P(A∩B)÷ P(B)
Probability that the student is both a freshman and a mathematics majorIn first place, let's define the following events:
F: The event that the student is a freshman.M: The event that the student is a mathematics major.You know:
A certain college class contains 51 students. 23 students are freshmen. → P(F)= 23÷51 → P(F)= 23/5130 students are mathematics majors. → P(M)= 30÷51 → P(M)= 30/517 students are neither a freshman or a mathematics mayor → P [(F∪M)']= 7÷51= 7/51The probability that a student is a freshman or a mathematics mayor is:
P [(F∪M)']= 1- P(F∪M)
7/51= 1 - P(F∪M)
7/51 - 1= -P(F∪M)
-44/51= -P(F∪M)
44/51= P(F∪M)
So, the probability that the student is both a freshman and a mathematics major is calculated as:
P(F∪M)= P(F) + P(M) -P(F∩M)
44/51= 23/51 + 30/51 - P(F∩M)
44/51- 23/51 - 30/51= - P(F∩M)
-3/17= - P(F∩M)
3/17= P(F∩M)
Finally, the probability that the student is both a freshman and a mathematics major is 3/17.
Probability that a student is a mathematics major being a freshmanThe probability that a student is a mathematics major, knowing that he is also a freshman, is calculated as:
P(M|F) = P(M∩F)÷ P(M)
So:
P(M|F) = 3/17÷ 30/51
P(M|F) = 3/10
Finally, given that the student selected is a freshman, what is the probability that he is also a mathematics major is 3/10.

Answers
Cost of a bottle of juice is $ 1.62
Equation for determining the cost of juice is 1.56 + 20x = 33.96
Given,
The cost of a bag of chips = $ 1.56
Number of juice bottles bought by Sarah = 20 pack
Total cost before tax = $ 33.96
Cost of one bottle of juice = x
We have to find x:
Then the equation will be:
1.56 + 20x = 33.96
Add -1.56 to both sides:
1.56 + 20x - 1.56 = 33.96 - 1.56
We get,
20x = 32.4
Now find x,
x = 32.4 / 20
Then,
x = 1.62

What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
We have,
Alfalfa hay = 18 % CP
Clover = 4% CP.
The total amount of ration is 600 lbs of a 13% CP.
Let x pounds of alfalfa hay have been used.
The amount of clover will be 600 - x lbs.
The CP amount in 600 lbs mixture will be equal to the sum of CP amounts in x lbs alfalfa and (600 - x) lbs clover.
13% of 600 = 18% of x + 4% of (600 - x)
We need to find x.
13/100 x 600 = 18/100 x (x) + 4/100 x (600 -x)
78 = 18x / 100 + 24 - 4x/100

Step-by-step explanation:
Monthly Payment Formula
[tex]\sf PMT=\dfrac{Pi\left(1+i\right)^n}{\left(1+i\right)^n-1}[/tex]
where:
PMT = monthly payment.P = loan amount.i = interest rate per month (in decimal form).n = term of the loan (in months).Given:
P = $39.950 less any down payment.i = 10.25% / 12 = 0.1025/12n = 7 years = 7 × 12 = 84 monthsPart (a)Down payment = $0
⇒ P = $39,950
[tex]\implies \sf PMT=\dfrac{39950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]
[tex]\implies \sf PMT = 668.3892086[/tex]
Therefore, the monthly payment is $668.39.
Part (b)Down payment = $2,000
⇒ P = $39,950 - $2,000 = $37,950
[tex]\implies \sf PMT=\dfrac{37950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]
[tex]\implies \sf PMT = 634.9279215[/tex]
Therefore, the monthly payment is $634.93.
Part (c)Down payment = $3,000
⇒ P = $39,950 - $3,000 = $36,950
[tex]\implies \sf PMT=\dfrac{36950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]
[tex]\implies \sf PMT = 618.197278[/tex]
Therefore, the monthly payment is $618.20.

Answer:
250°Step-by-step explanation:
360° - the know angles
360 - 20 - 70 - 20 = 250°
Step-by-step explanation:
Well this is a full circle, and in a full circle, theres 360 degrees.
So if we add up 20, 70 and 20 degrees, it comes to a total of 110 degrees.
If we subtract 110 d from 360 d, we get 250 degrees. Therefore,
X = 250 degrees

⦁ Sally and Mary are best friends. Their families both went to the beach on June 1st to celebrate the start of summer vacation. After that day Sally’s family continues to go to the beach every 4 days. Mary’s family only goes to the beach every 14 days.
⦁
⦁ Would you use Greatest Common Factor or Least Common Multiple to help solve this problem?
Answers
Based on the fact that Mary's family goes every 14 days and Sally's family goes every 4 days, the method of solving this problem is the Least Common Multiple.
When to use Least Common Multiple?The Least Common Multiple is used to find out when two or more events will occur at the same time if those events occur at fixed intervals that are different from each other.
Sally's family goes to the beach every 4 days and Mary's family goes every 14 days.
You can therefore solve for the day that they will next meet on the beach using their Least Common Multiple which is 28. They will next be at the beach on the same day after 28 days.
