What is series ?a series is a crude description of the operation of adding infinitely many quantities to a given initial amount one after the other.
A series is systematic way in which numbers are arranged which are defined by a particular function.
How to solve?Given views pr day =5
everyday number of views double
hence series becomes=
[tex]=2^{0}*5+2^{1} *5+2^{2} * 5+2^3*5.....[/tex]
[tex]=5+2*5+4*5+8*5+16*5+32*5+64*5+128*5....[/tex]
now 640 people watch video
hence 640=128*5= day 8
Hence on day 8, 640 views are obtained.

A coconut tree had 6 coconuts that fell to the ground? If 25% of the coconuts on the tree fell to the ground, how many coconuts were originally on the tree?
Answer: 24 coconuts
Step-by-step explanation:
Let the number of coconuts that were originally on the tree be represented by x.
The information given in the question can then be presented to an equation as:
25% × x = 6
25/100 × x = 6
0.25 × x = 6
0.25x = 6
x = 6/0.25
x = 24
Therefore, 24 coconut were originally on the tree.
Answer: 24 coconuts

After simplifying the expressions on each side of an equation, you observed that the coefficients of x and the constants
on each side of the equal sign were the same. What kind of solution(s) do you expect for this equation?
No solution
Infinitely many solutions
One unique solution
T
Answer:
The solution has infinitely many solutions.
Step-by-step explanation:
Correct option is - The solution has infinitely many solutions.
The expression is of the form -
ax + b = ax + b
In the expression , any value of x will satisfy
So, we get infinitely many solution
For example -
for x = 1
a(1) + b = a(1) + b
⇒ a + b = a + b
satisfied.
for x = 2
a(2) + b = a(2) + b
⇒ 2a + b = 2a + b
satisfied.
Hereon, for any value of x , it satisfies.
J.D. power and Associates calculates and publishes various statistics concerning car quality. The dependability score measures problems experienced during the past 12 months by original owners of three-year-old vehicles (those that were introduced for the 2017 model year).

Answer:
0.281 ; 0.864
Step-by-step explanation:
1.)
p decreases as n increases (n increases, p--> 0)
λ ≥ 0
P(x = x) = (e^-λ * λ^x) ÷ x!
λ for Ford = 1.27
B) zero problems :
P(x = 0) :
(e^-1.27 * 1.27^0) ÷ 0! = 0.281
P(x = 0) = 0.281
Two or fewer problems :
P(x ≤ 2) = p(x = 0) + p(x = 1) + p(x = 2)
P(x ≤ 2) = 0.281 + 0.357 + 0.226
P(x ≤ 2) = 0.864
D.) It allows for early detection and thus adequate curtailment of the problem at an a stage in which it seems easier to curb.

Explanation:
Label the center point of the circle as point G.
Also, label the top and bottom tangent points as H and J respectively. This means that H is on line segment ED, while J is on line segment EF.
The given arc measure of 100 degrees directly leads to the central angle HGJ to be 100 degrees.
Focus on quadrilateral EHGJ. It has two right angles at points H and J since they are tangent points. Angle G of this quadrilateral was found to be 100. Let's find angle E
E+H+G+J = 360 ..... any four angles of a quadrilateral add to 360
E+90+100+90 = 360
E+280 = 360
E = 360-280
E = 80
Or as a shortcut, we can note that angles E and G must add to 180, since H+J = 90+90 = 180, making up half of 360.
So, E+G = 180 leads to E+100 = 180 which solves to E = 80.
Once we know that E = 80, this leads to angle DEF to be 80 degrees.
This is an inscribed angle that subtends arc DF. By the inscribed angle theorem, we double the inscribed angle value to get the arc measure
arc DF = 2*(inscribed angle DEF)
arc DF = 2*(80)
arc DF = 160 degrees
Find the following for the function f(x) = x/x^2+1

(b) f(9)
(f) f(x + 1)
(c) f(-9)
(g) f(3x)
(d) f(-x)
(h) f(x + h)
Step-by-step explanation:
step 1. f(0) = 0/(0^2 + 1) = 0/1 = 0
step 2. -f(x) = -x/(x^2 + 1)
step 3. f(9) = 9/(9^2 + 1) = 9/82.
A function is defined as a relation between a set of inputs having one output each. The values can be written as shown below.
What is function explain?A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given function is f(x) = [tex]\frac{x}{x^{2} +1}[/tex], therefore, the values can be found by as shown below. Therefore, we can write,
(a) f(0) = 0/0+1 = 0
(e) – f(x) = - [ x / (x²+1)]
(b) f(9) = 9/(81 + 1) = 9/82
(f) f(x + 1) = (x + 1)/(x² + 2x + 2)
(c) f(-9) = - 9/(81 + 1 ) = -9/82
(g) f(3x) = 3x/(9x² + 1)
(d) f(-x) = -x/(x² + 1)
(h) f(x + h) = (x + h) / [(x+h)²+1]

Give the slope and the y-intercept of the line y = x – 4.
Make sure the y-intercept is written as a coordinate.
Given:
The equation of a line is
[tex]y=x-4[/tex]
To find:
The slope and y-intercept of the line.
Solution:
We have,
[tex]y=x-4[/tex] ...(i)
The slope intercept form of a line is
[tex]y=mx+b[/tex] ...(ii)
Where, m is the slope and b is the y-intercept.
On comparing (i) and (ii), we get
[tex]m=1,b=-4[/tex]
Slope of the line = 1
y-intercept of the line = -4
The coordinate form of y-intercept is (0,b). So, the y-intercept of the given line is (0,-4).
Therefore, the slope of the line is 1 and the y-intercept is (0,-4).

Answer:
A) length = 9cm, width = 4 cm
Step-by-step explanation:
The key word "times" refers to multiplication, so if you're trying to find dimensions at 1/4 times its original size, you need to multiply the original dimensions by 1/4.
l = 36
new l = 36 (1/4)
= 36/4
= 9 cm
w = 16
new w = 16 (1/4)
= 16/4
= 4 cm

In circle C, IL is a diameter, ∠ICR = (3x + 5)°, and angle∠RCL = (x – 1)°.
find X and (arc) ILR
The measure of arc ILR is 223 degrees
Circle geometryThe sum of angle on a straight line is 180 degrees
Given the following parameter
∠ICR = (3x + 5)°, and
∠RCL = (x – 1)°.
Taking the sum:
3x + 5 + x - 1 = 180
4x + 4 = 180
4x = 176
x = 176/4
x = 44
arc ILR = 180 + arcRL
arc ILR = 180 + 44 - 1
arc ILR = 223 degrees
Hence the measure of arc ILR is 223 degrees

Step-by-step explanation:
An oil exploration company currently has two active projects, one in Asia and the other in Europe. Let A be the event that the Asian project is successful and B be the event that the European project is successful. Suppose that A and B are independent events with P(A) = 0.5 and P(B) = 0.3. (a) If the Asian project is not successful, what is the probability that the European project is also not successful? Explain your reasoning. Since the events are independent, then A′ and B′ are not independent. Since the events are independent, then A′ and B′ are independent. Since the events are not independent, then A′ and B′ are mutually exclusive. Since the events are independent, then A′ and B′ are mutually exclusive. (b) What is the probability that at least one of the two projects will be successful? (c) Given that at least one of the two projects is successful, what is the probability that only the Asian project is successful? (Round your answer to three decimal places.)
Answer:
0.7 ; 0.65 ; 0.115
Step-by-step explanation:
Step-by-step explanation:
P(A) = 0.5 ; P(B) = 0.3
P(not successful) = P(B') = 1 - 0.3 = 0.7 ; P(A') = 1 - 0.5 = 0.5
1.)
Both events are independent events, hence the outcome of one does not depend on the other. That is the failure of the Asian project has nothing to do with the European project.
Probability that European project isn't successful;
P(B') = 1 - P(B) = 1 - 0.3 = 0.7
2.)
Probability that atleast one of the 2 projects is successful :
P(AUB) = P(A) + P(B) - P(AnB)
P(AnB) = P(A) * P(B) = 0.5 * 0.3 = 0.15
P(AUB) = 0.5 + 0.3 - 0.15 = 0.65
3.)
Probability that only the Asian project is successful, given that atleast one of the two projects is successful :
[P(A) - P(AnB)] ÷ P(AuB)
[0.5 * 0.15] ÷ 0.65
= 0.075 ÷ 0.65
= 0.1153846
= 0.115
