Step-by-step explanation:
First you find 3.5% of $3500.Which is $122.50.Then multiply $122.50 by 5 years.So then your answer will be $612.50.The scatter plot shows the number of years of experience, x , and the amount charged per hour, y , for each of 24 dog sitters in Texas. (a) Write an approximate equation of the line of best fit for the data. It doesn't have to be the exact line of best fit. (b) Using your equation from part (a), predict the amount charged per hour by a dog sitter with 10 years of experience.
a) An approximate equation of the line of best fit for the data is,
⇒ y = 18/13 (x - 7)
b) The amount charged per hour by a dog sitter with 10 years of experience is, $54/13
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The scatter plot shows the number of years of experience, x , and the amount charged per hour, y , for each of 24 dog sitters in Texas.
Now, Add a line of best fit (see attached).
Here, The two points on the line are,
⇒ (7, 0) and (20, 18)
Thus, Use these points to find the slope of the line is,
⇒ m = (18 - 0) / (20 - 7)
⇒ m = 18 / 13
Use the found slope and one of the points in the point-slope form of the linear equation to find an equation for the line of best fit:
⇒ y - y₁ = m (x - x₁)
⇒ y - 0 = 18/13 (x - 7)
⇒ y = 18/13 (x - 7)
Substitute x = 10 we get;
⇒ y = 18/13 (x - 7)
⇒ y = 18/13 (10 - 7)
⇒ y = 18/13 × 3
⇒ y = $54/13
Thus, An approximate equation of the line of best fit for the data is,
⇒ y = 18/13 (x - 7)

What is Percentage?percentage, a relative value indicating hundredth parts of any quantity.
We can use the formula for compound interest:
[tex]A = P (1 + r/n)^(^n^t^)[/tex]
where A = the final amount, P = the principal (initial investment), r = the annual interest rate (as a decimal), n = the number of times the interest is compounded per year and t = the time in years
We know that P = £7500, t = 4 years, and A = £7866.53.
Let n is 1
Plugging in the values we know, we get:
£7866.53 = £7500 (1 + r/1)⁴
Simplifying the equation:
(1 + r)⁴ = 1.04887
Taking the fourth root of both sides:

Suppose an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t)=-16t^2+48t+120. Find the average velocity from t=2 to t=4.
Type your answer as a number with no units.
The average velocity from t = 2s to t = 4s would be - 48 ft/s.
What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.
Given is that an object is thrown upward with initial velocity of 48 feet per second from a high of 120 feet. The height of the object t seconds after it is thrown is given by h(t) = - 16t² + 48t + 120.
Average velocity
Average rate of change of velocity with time is called average velocity. Mathematically -
v{avg.} = Δx/Δt .... Eq { 1 }
Δx = x(4) - x(2)
Δx = - 16(4)² + 48(4) + 120 - {- 16(2)² + 48(2) + 120}
Δx = - 96
Δt = 4 - 2 = 2
So -
v{avg.} = Δx/Δt = -96/2 = - 48 ft/s
Therefore, the average velocity from t = 2s to t = 4s would be - 48 ft/s.

if the probability that a portfolio outperforms its benchmark in any quarter is 0.75, the probability that the portfolio outperforms its benchmark in three or fewer quarters over the course of a year is closest to: 0.26 0.42 0.68
The closest solution to this total among the available possibilities is 0.68, indicating that the portfolio is likely to surpass its benchmark in three or fewer quarters over the course of a year.
What is probability?The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms.
Here,
The probability that the portfolio outperforms its benchmark in three or fewer quarters over the course of a year is the sum of the probabilities of outperforming the benchmark in exactly 0 quarters, 1 quarter, 2 quarters, and 3 quarters.
Since the probability of outperforming the benchmark in any quarter is 0.75, the probability of not outperforming the benchmark in a quarter is 1 - 0.75 = 0.25.
The probability of not outperforming the benchmark in exactly 0 quarters is 0.25⁰ = 1
The probability of not outperforming the benchmark in exactly 1 quarter is 0.25¹= 0.25
The probability of not outperforming the benchmark in exactly 2 quarters is 0.25² = 0.0625
The probability of not outperforming the benchmark in exactly 3 quarters is 0.25³ = 0.015625
So, the probability of outperforming the benchmark in exactly 0 quarters, 1 quarter, 2 quarters, and 3 quarters is 1 - 0.25⁰, 1 - 0.25¹, 1 - 0.25², and 1 - 0.25³, respectively.
The sum of these probabilities is the probability of outperforming the benchmark in three or fewer quarters over the course of a year:
P(outperform in three or fewer quarters) = 1 - 0.25⁰ + 1 - 0.25¹ + 1 - 0.25² + 1 - 0.25³
This expression can be calculated to get an exact answer, but to get the closest answer to the options given, we can round off the intermediate results to 2 decimal places:
P(outperform in three or fewer quarters) = 1 + 0.75 + 0.94 + 0.98
The closest answer to this sum among the options given is 0.68, so the probability that the portfolio outperforms its benchmark in three or fewer quarters over the course of a year is closest to 0.68.

If f(x)=2(x)+3=5 what is f(-2)
As a result, f(-2) has a value of -1 by simply substituting the value of x in the function. as Each function is given a domain and a codomain, often known as a scope.
what is function ?Math deals with numbers with their variants, formulae and adjacent tissues, structures and associated locations, and areas where they might be found. The term "function" refers to the connection between a series of inputs, of which each has a corresponding output. A function is a connection between the inputs and outputs where each input result in a single, unique output. A domain as well as a codomain, or scope, are allocated to each function. Functions are generally symbolized by the letter f. (x). The input is an x. On functions, another functions, many-to-one functions, within operations, and on functions are the four main types of functions that are available.
