The formula for given sequence is aₙ = 0.3(-0.2)ⁿ⁻¹ i.e. E.
What exactly is a sequence?
A sequence is a collection of numbers that follows pattern. Olivia, for example, has been offered a position with a beginning monthly pay of $1000 and a yearly raise of $500. Can you figure out her monthly pay for the first three years? The prices will be $1000, $1500, and $2000. Note that Olivia's income over a number of years creates a sequence as they follow a pattern where the numbers increase by $500 each time.
Now,
Given sequence is 0.3,-0.06, 0.012, -0.0024, 0.00048, ...
Of all given options only E satisfies the given sequence because
for E
a₁=0.3*-0.2¹⁻¹
=0.3*1
=0.3
a₂=0.3*-0.2²⁻¹
=-0.3*0.2
=-0.006
a₃=0.3*-0.2³⁻¹
=0.3*0.04
=0.012
hence,
The formula for given sequence is aₙ = 0.3(-0.2)ⁿ⁻¹.

be said about the parabola?
Answer: A parabola can be defined as the set of all points that are equidistant from a focus and a directrix. Based on the information provided, the focus of the parabola is (0, 4) and the directrix is y =.
The parabola will open upwards or downwards depending on the location of the focus and the directrix. Since the focus is at (0, 4), and the directrix is at y =, the parabola must open upwards. The axis of symmetry of the parabola will pass through the focus and will be perpendicular to the directrix.
Without more information, it is not possible to fully determine the shape and equation of the parabola. The shape of the parabola and its equation can be found by using the focus and directrix and other information, such as the vertex or a point on the parabola.

A Smoothie is mixed with strawberries and bananas in the ratio 7:3. Gill
makes a smoothie using 144g of bananas. How many grams of
Strawberry does she use?
Answer: et's call the amount of strawberries Gill uses "x" grams. We know that the ratio of strawberries to bananas is 7:3, so we can set up an equation:
x/144 = 7/3
To solve for x, we'll multiply both sides of the equation by 144:
x = 7/3 * 144
x = 7 * 48
x = 336
So Gill uses 336 grams of strawberries in the smoothie.

uppose that a particular nba player makes of his free throws. assume that late in a basketball game, this player is fouled and is awarded two free throws. a. what is the probability that he will make both free throws? (to 4 decimals) b. what is the probability that he will make at least one free throw? (to 4 decimals)
Answer:
a. 0.81
b. 0.81
Step-by-step explanation:
Let's assume that the player makes x% of his free throws. Then, the probability that he will make both free throws is (x/100)^2, and he will make at least one free throw is 1 - (1 - x/100)^2.
So if he makes 90% of his free throws, then:
a. The probability that he will make both free throws is (90/100)^2 = 0.81.
b. The probability that he will make at least one free throw is 1 - (1 - 90/100)^2 = 1 - (1 - 0.9)^2 = 1 - 0.19 = 0.81.
The answers to the questions rounded to 4 decimal places are:
a. 0.81

The histogram of the magazine ranks the best paying college degrees in a country is illustrated below.
A histogram is a graphical representation of data that displays the frequency distribution of a set of continuous or discrete data
To construct a histogram, we would first need to determine the range of the data. In this case, the range would be the difference between the highest and lowest starting salaries or mid-career salaries. We would then divide the range into several intervals or "bins" of equal width.
For example, if we use a bin width of $10,000, the first bin would be $40,000-$49,999, the second bin would be $50,000-$59,999, and so on.
We would then count the number of degrees that fall into each bin and plot the counts as bars on a graph, with the bin ranges on the x-axis and the frequency counts on the y-axis. The resulting graph would be a histogram, showing the distribution of the data.
It is important to label the axes of the histogram and include a title that accurately reflects the data being presented.

Lisa's average score on 4 tests is 82. What does she need to score on her fifth test to have an average final score of 85?
Answer:
Lisa would need to score 97 on her 5th test.
Step-by-step explanation:
If Lisa has an average score of 82 on 4 tests, then the total sum of her scores would be 82 multiplied by 4, which is equal to 328.
If she wants an average final score of 85 over 5 tests, then the total sum of her scores needs to be 425 (i.e. 85 multiplied by 5).
To determine what she needs to get on her 5th test we need to subtract 328 from 425.
425 - 328 = 97
Company F sells fabrics known as fat quarters, which are rectangles of fabric created by cutting a yard of fabric into four pieces. Occasionally the manufacturing process results in a fabric defect. Let the random variable X represent the number of defects on a fat quarter created by Company F. The following table shows the probability distribution of X.
X 0 1 2 3 4 or more
probability 0. 58 0. 23 0. 11 0. 05 0. 03
If a fat quarter has more than 2 defects, it cannot be sold and is discarded. Let the random variable Y represent the number of defects on a fat quarter that can be sold by Company F.
(a) Construct the probability distribution of the random variable Y.
(b) Determine the mean and standard deviation of Y. Show your work.
Company G also sells fat quarters. The mean and standard deviation of the number of defects on a fat quarter that can be sold by Company G are 0. 40 and 0. 66, respectively. The fat quarters sell for $5. 00 each but are discounted by $1. 50 for each defect found.
(c) What are the mean and standard deviation of the selling price for the fat quarters sold by Company G?
The probability distribution of the random variable Y is 0.63, 0.25, 0.12. The mean of y is 0.4899 and the std deviation of y is 0.6999 and the mean of the selling price for the fat quarters sold by Company G is $4.4 and the std deviation for the same is $0.99
a) x = number of defects on a fat quarter
to be sold, X must be, X ≤ 2
y = number of defects on the sellable fat quarter,
now from the table, P [fat quarter being sellable]
=P [X ≤ 2]
=0.58 + 0.23 + 0.11
= 0.92
Therefore, P[y-0] = P[x=0Ix≤2]
=[tex]\frac{P[x=0][x < 2]}{P[x < 2]}[/tex]
=P[y=0] = 0.63
P[y=1] = P[x=1Ix≤2]
P[y=1] = [tex]\frac{0.23}{0.92}[/tex]
=0.25
P[y=2] = P[x=2Ix≤2]
P[y=2] = [tex]\frac{0.11}{0.92}[/tex]
= 0.12
y------------------0--------1---------2
probability---0.63----0.25----0.12
b)mean of y = E(y)
=0²×0.063+1×0.25+2×0.12
=0.25+0.24
=0.49
now we know that E(y²) = 0²×0.63+1²×0.25+2²×0.12
=0.25+0.48
=0.73
E(y²) - [E(y)]²
=0.73-0.49²
=0.4899
std deviation of y = 0.6999
c) now that we have E(G) = 0.40, √v(G) = 0.66
let s be selling price of fat quarters, then s = 5.00 - 1.50 × (G)
therefore = 5-1.5×0.4
=5-0.6
=$4.4 is the mean selling price.
now for the standard deviation price = v[5-1.5G]
=v(5)+1.5² v(G)
=0+2.25×0.66²
=v(s)= 0.9801
standard deviation of sp =√v(s)
=$0.99

Emma is starting a cupcake business and borrows money from Dixons dynamite deals (DDD) .she agrees to pay back the loan after 10 years by making one payment of 80,000 , interest is compounded and fixed at 14,6% per annum.hpw much did emma borrow from (DDD) ?
The amount (present value) that Emma borrowed from Dixons Dynamite Deals (DDD) to repay after 10 years with a one-time payment of $80,000 at 14/6% compounded interest per annum is not more than $20,475.94.
Step-by-step explanation:
To find out how much Emma borrowed from Dixons Dynamite Deals (DDD), we can use the formula for the future value of a loan with compound interest:
Future Value (FV) = Principal Amount (P) * (1 + r)^n
Where:
P = Principal amount (the amount borrowed)
r = Interest rate per period (in decimal form)
n = Number of periods
In this case:
Future Value (FV) = $80,000 (the payment Emma will make after 10 years)
Interest rate (r) = 14.6% per annum = 0.146 (in decimal form)
Number of periods (n) = 10 years
Now, let's calculate the principal amount (P):
$80,000 = P * (1 + 0.146)^10
Now, let's solve for P:
P = $80,000 / (1.146)^10
P ≈ $80,000 / 2.97804
P ≈ $26,874.94
So, Emma borrowed approximately $26,874.94 from Dixons Dynamite Deals (DDD) to start her cupcake business.

The probability that an event will occur is determined by probability: P(A) = f / N. Probability and odds are related, but probability determines what the odds are. Probability is required before calculating the likelihood that an event will occur.
To find the probability of flaws, we can find the probability of no flaws first by dividing by 100:
P(no flaw) = 80/100 = 0.8
So then:
P(flaw) = 1 - P(no flaw) = 1 - 0.8 = 0.2
P(flaw) = 0.2
B) First, we need to find the probability of major flaws:
P(major flaws) =
P(Major flaws) = 0.05
So to find the probability of no major flaws:
P(No major flaws) = 1 - P(major flaws) = 1 - 0.05 = 0.95

There are 50 ways for Marvin to reach his destination without passing through the forbidden point.
To solve this problem, we can use the unitary method. This method involves breaking the problem down into smaller, simpler units to solve it more easily.
In this case, we can break the path from Marvin's starting point to his destination into two smaller paths. The first path is from (0,0) to (1,4), and the second path is from (1,4) to (4,6).
There are five paths from the bottom left corner to the point (1,4) that do not go through the forbidden point.
Once Marvin reaches the point (1,4), he can only go up or to the right to reach his destination. So, we need to count the number of ways to get from (1,4) to (4,6)

Base case: For k = 1, removing the root of a 1st order binomial tree results in zero smaller binomial trees, which is true.
Inductive hypothesis: Assume that removing the root of a k-th order binomial tree results in k binomial trees of smaller orders, for some positive integer k.
Inductive step: We want to prove that removing the root of a (k+1)-th order binomial tree results in (k+1) binomial trees of smaller orders.
By definition, a (k+1)-th order binomial tree, denoted by B(k+1), is formed by joining two k-th order binomial trees, denoted by Bk, with one of them as the leftmost child of the root of the other. Let us remove the root of B(k+1) to obtain a new binomial tree, denoted by B'.
Since B(k+1) is formed by joining two k-th order binomial trees, we can apply the inductive hypothesis to each of them to obtain that removing their roots results in k smaller binomial trees each. Let these smaller binomial trees be denoted by B1, B2, ..., Bk and C1, C2, ..., Ck,
respectively.
Now, consider B' and observe that it is a k-th order binomial tree, since it has k children, each of which is a smaller binomial tree. Moreover, B' is obtained from B(k+1) by removing the root, which is the parent of the two k-th order binomial trees Bk and Ck. Thus, we have decomposed B' into k smaller binomial trees, namely B1, B2, ..., Bk and C1, C2, ..., Ck.
Therefore, we have shown that removing the root of a (k+1)-th order binomial tree results in (k+1) binomial trees of smaller orders, which completes the induction.

Write a piece wise function for each function graphed below.
The piecewise function for the graph is given as follows:
y = -2, x < -4.y = 0.5x + 4, -4 < x ≤ 2y = -1.5x + 1, x > 1.How to define the piecewise function?A piecewise function is a function that has different definitions, depending on the input x of the function.
The three different definitions for the function in this problem are given as follows:
x < -4.-4 < x ≤ 2.x > 2.For x < -4, the function is constant at y = -2, hence:
y = -2, x < -4.
For -4 < x ≤ 2, the function is linear, with an slope of 0.5 and intercept of 4, hence:
y = 0.5x + 4, -4 < x ≤ 2
For x > 2, the function is also linear, with slope of -1.5, hence at x = 0 it would assume a value of 1, thus:
y = -1.5x + 1, x > 1.

Answer: 5 1/4
Step-by-step explanation:
emmas suitcase was extremely heavy so she decided to take some things out and weigh them. she started with a gift that weighed 30 pounds. Then, she took out all of her shower essentials and personal items that weighed 7 1/4 pounds. If her suitcase now weighs 21 2/3 pounds, how much did it weigh when she started?
Answer:
58 11/12
Step-by-step explanation:
Add up each item within the suitcase + the suitcase after taking out the items to find the weight of the suitcase at the beginning.
30 + 7 1/4 + 21 2/3
Convert the fractions to have a common denominator
30 + 7 3/12 + 21 8/12
Add these up to get 58 11/12.
Your school is going to start offering afterschool clubs they will be nine clubs to choose from to have clubs at least 23 students we will need to sign up for each one what is the least number of students that must sign up to have all nine clubs
At least number of students who must have signed up to have all nine clubs is equal to 207.
Number of clubs school going to start after school = 9 clubs
At least number of students need to sign up in each one of the club is equal to 23 students.
At least number of students need to sign up to have all in nine clubs is equal to :
At least number of student in 1 club > 23
⇒ At least number of student in 9 club > 23 × 9
At least number of student in 9 club > 207
Therefore, at least number of students need to signed up to have in all nine given clubs are 207 students.
