Tony is working on an arithmetic sequence where t(1) =4 and t(8) =67 Write the explicit equation and recursive equation for this sequence. Is 500 a term of the sequence? Explain why or why not.
This can go on forever, we can then establish the recursive formula which states:
t(n+1)=t(n)+dort(n)=t(n-1)+dExplicit formula:t(2)=t(1)+d
t(3)=t(2)+d, but t(2)=t(1)+d
t(3)=t(1)+d+d
t(3)=t(1)+2d
t(4)=t(1)+3d
t(n)=t(1)+(n-1)dWe can calculate d for these equations:t(8)=t(1)+7d67=4+7d7d=63d=9Explicit relation:t(n)=4+9(n-1)t(n)=9n-5Recursive relation:t(n)=t(n-1)+9t(500)=9(500)-5=4500-5=4495can you help me figure this out?

The given pyramid is composed of two right angle triangles. Notice the triangles of the pyramid share a common side. With the help of it, we can figure out x
recall Pythagoras theorem
[tex] {a}^{2} + { b }^{2} = {c}^{2} [/tex]
Case-1: Finding the opposite sidehere,
a=4c=10To find:
bnow plug in the value of a and c in the formula respectively:
[tex] {4}^{2} + { b }^{2} = {10}^{2} \\ \implies {b}^{2} = {10}^{2} - {4}^{2} \\ \implies {b}^{2} = 84 \\ \implies \boxed{ b_{1} = 2\sqrt{21}}[/tex]
Case-2: Finding xhere,
[tex]b_1 \implies c=2\sqrt{21}[/tex]b=8a[tex]\implies[/tex] xUtilizing Pythagoras theorem yields:
[tex] {x}^{2} + { 8}^{2} = {(2\sqrt{21})}^{2} \\ \implies {x}^{2} = {(2\sqrt{21})}^{2} - {8}^{2} \\ \implies {x}^{2} = 20\\ \implies \boxed{ x= 2\sqrt{5}}[/tex]

Find+the+z-scores+that+separate+the+middle+69%+of+the+distribution+from+the+area+in+the+tails+of+the+standard+normal+distribution
Answer and Explanation:
1 - 0.69/ 2 = 0.155
0.155 = -1.02
(-1.02, 1.02) = z
The z -score separates the middle 69% of the distribution from the area in the tails of the standard normal distribution is (-1.02, 1.02).
What is a z- score?Z- score refers to how much a given value differs from the standard deviation.
The z -score separates the middle 69% of the distribution from the area in the tails of the standard normal distribution.
α = 1 - 0.69/ 2
α = 0.155
0.155 = -1.02
z = (-1.02, 1.02)

Answer:
0.0816
Step-by-step explanation:
Given:
Total number of students = 5000Number of students taking an online class = 1200Number of students prefer watching baseball to football = 1700Let O = Students taking an online class
Let B = Students prefer watching baseball to football
Therefore,
P(O) = 1200/5000 = 0.24
P(B) = 1700/5000 = 0.34
If events O and B are independent,
⇒ P(O ∩ B) = P(O) · P(B)
= 0.24 × 0.34

what is a pair lines that are parallel
Answer:
The pairs of lines that do not intersect or meet at any point are called parallel lines. These lines lie on the same plane but do not intersect. The line segments or rays that lie on the same plane but do not intersect are also parallel.
Step-by-step explanation:
Answer
A parallel line is a position of two lines on a plane that does not have a point of intersection even though the two lines are extended.Geometrically, parallel lines will never meet each other because they have the same slope (gradient). Parallel lines do not have to be the same length

You have decided to purchase a car for $25,625. the credit union requires a 10% down payment and will finance the balance with a 9% annual interest loan for 36 months. the sales tax in your city is 7.5%, and the license and title charges are $175.13. what is the total purchase price of the car including tax, license, and title? round your answer to the nearest cent. a. $24,949.80 c. $27,722.01 b. $24,967.32 d. $27,735.14
The total purchase price of the car including tax, license, and title $27,722.01.
The purchase price of a car is $25,625 the credit union requires a 10% down payment and an annual interest 9% loan for 36 months. The sales tax is given 7.5%, and the license and title charges are $175.13.
What is the total sale?The total sale is the product of the selling price and one plus the sales tax rates.
Total sale = selling price × (1 + sales tax rate)
The price of the car including tax
= $25,625 × (1 +7.5%)
= $27,546.88
By adding license and title charges to the amount, we get
= $27,546.88 +175.13
= $27,722.01
Hence, The total purchase price of the car including tax, license, and title $27,722.01.
