Answer:
p = 19
x = 64
y = 100
Step-by-step explanation:
114 = 6p
Divide by 6 into both sides
p = 19
x/4 = 16
Times 4 into both sides
x = 64
75 = y - 25
Add 25 to both sides
y = 100
17. Louis is offered an interest rate of 6.35%
for an investment with continuous
compounding. What is his equivalent rate
of interest with simple compounding?
[A] 1.23 or 12.3%
[B] 0.0593 or 5.93%
[C] 0.423 or 42.3%
[D] 0.0656 or 6.56%
[E] 0.0615 or 6.15%
The rate of interest for simple compounding if Louis is offered an interest rate of 6.35% for an investment with continuous compounding, is 0.0656 or 6.56%, so option D is correct.
What is interest?When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.
Given:
Louis is offered an interest rate of 6.35% for an investment with continuous compounding,
Here, P will be the same, the amount will be the same and the time period will be the same then,
The amount in simple compounding = The amount in continuous compounding
[tex]P(1 + r)^t = Pe^{Rt}[/tex]
Here, r is the rate of interest for simple compounding,
[tex]1 + r = e^{0.0635}[/tex]
r = 1.0656 - 1
r = 0.06556
r = 0.0656
r = 6.56%
Thus, the rate of interest for simple compounding is 6.56%.

Answer:
7 feet
Step-by-step explanation:
Because they divided the length by 5 to get the scaled length so you would do the same for the width.
Answer:
26 inches squared
Step-by-step explanation:
If the real length is 30 feet and the scale drawing is 6 inches its 5:1

The graph of the parabola declines through (-5, 2), (-3, 0), (-2, 0), (0, 1), (1, 2), (2, 3), (3, 5) on the x y coordinate plane represents the function.
What is a Function?A function is defined as the relation between the x and y coordinates such that no value of x maps to two values of y.
A vertical line test is a test used to determine whether the graph given is a function or not. This is a test where we draw a vertical line passing through a point x. If the graph is a function, then the vertical line will not intersects the graph at two points.
That is, no x coordinate maps to more than 1 y coordinate.
In the first graph of ellipse, the value -5 maps to two values 3 and 5. So this is not a function.
In the parabola all x values only maps to one y value. So this graph represents a function.
In the third graph, the value 3 maps to three values of y, 3, 2, and 1. So this is also not a function.
In the fourth graph, -2 maps to both 4 and 2, which also indicates that the given graph is not a function.
Hence the second graph of the parabola represents a function.

find a recurrence relation for the number of bit strings of length n that contain three consecutive 0s. b) what are the initial conditions? c) how many bit strings of length seven contain three consecutive 0s?
a) A recurrence relation for the number of bit strings of length n that contain three consecutive 0s :
a_n = a_(n-1) + a_(n-2) + a_(n-3) + 2^(n-3) for n ≥ 3
b) The initial conditions are:
a_0 = a_1 = a_2 = 0 and a_3 = 1
c) There are 47 bit strings of length seven contain three consecutive 0s
Let s_n be a string of length n that does not have 3 consecutive 0's, and a_n be the number of strings that contain three consecutive 0's
Consider a string of length n -1 that does not have 3 consecutive 0's, s_(n-1)
If we add 1 to this string, then we get a string s_n.
Consider a string s_(n-2)
If we add 10 at the end, then we get a string s_n
Now consider a string s_(n-3)
If we add 100 at the end we get a string s_n.
Now we got all possible strings s_n: that end in 1 (i.e. the last 3 digits could be 001, 011, 101 and 111),
Those strings that end in 10 (i.e. the last 3 digits could be 010 and 110)
and those strings that end in 100. There are no other possibilities without having 3 consecutive zeros.
In the third case, there are a_(n-3) possibilities. And, in the fourth case, there are 2^(n-3) possibilities.
Hence the recurrence relation is
So, a_n = a_(n-1) + a_(n-2) + a_(n-3) + 2^(n-3) for n ≥ 3
The initial conditions are a_0 = a_1 = a_2 = 0 and a_3 = 1
The recurrence gives the sequence of positive integers 0, 0, 0, 1, 3, 8, 20, 47, 107, 238, 520, 1121, 2391, . . . .
Hence there are a_7 = 47 bit strings of length seven that contain
three consecutive 0's.
Therefore, a) the recurrence relation:
a_n = a_(n-1) + a_(n-2) + a_(n-3) + 2^(n-3) for n ≥ 3
b) Initial conditions: a_0 = a_1 = a_2 = 0 and a_3 = 1

What is simple interest?
The interest on a loan or principal amount can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more. When you pay back a loan, the monthly interest is deducted first, and any remaining funds are applied to the principle.S.I = Pnr / 100
where P = prinicipal
n= number of years
r = rate of interest
= 45000 * 2 * 8 / 100
= 810000 /100
= $8100
where, the divide by number of months
Balance= 8100 / 96

From the graph the curve cross the x -axis at X=1
Therefore the expression is (x-1)
And at (-) x axis at X=-2 it is the turning point.

Total price paid by Michael for the basket of mangoes is $4.48.
For the calculation of total price, price of sales tax will be added with selling price. Forming the equation -
Total price = 4 + 12%×4
Calculating the percentage of sales tax on Right Hand Side of the equation
Total price = 4 + 12×4/100
Solving the percentage part on Right Hand Side of the equation
Total price = 4 + 0.48

I left a desmos explanation on my previous answer
what is meant by a type i error? a type i error occurs when the null hypothesis is rejected when it is true. the null hypothesis is not rejected when it is false.
Type I errors (also known as a "false positive") occur when a test erroneously rejects a true null hypothesis. In other words, the test incorrectly concludes that the observed effect is significant or real when, in fact, it is not.
A type I error is a statistical mistake where the null hypothesis is rejected, despite it being true. This is also known as a false positive. This means that the test concluded that the observed effect was significant when in reality, it was not. Type I errors are more likely to occur when the sample size is small or when too many tests are conducted at once. To avoid type I errors, it is important to use an appropriate sample size and to consider the power of the test before conducting it.
