Answer:
b
Step-by-step explanation:
b. There is 5% probability that a true null hypothesis will be rejected.
A p-value of 0.05 represents the probability of obtaining a test statistic as extreme or more extreme than the one observed under the assumption that the null hypothesis is true. In other words, it is the probability of observing the data or more extreme data assuming the null hypothesis is true. It is also the threshold level of significance beyond which the null hypothesis is rejected in favor of the alternative hypothesis. A p-value of 0.05 means that there is a 5% probability that the observed results occurred by chance under the null hypothesis and that there is a 95% probability that the observed results occurred due to a real effect.

$2,400 and received full credit.
a. If Rolfes Company pays the invoice within the
discount period, what is the amount of cash required for
the payment? If required, round the answer to the
nearest dollar.
b. What account is debited by Rolfes Company to record
the return?

Therefore , the solution of the given problem of percentage comes out to be the sum of money needed to complete the transaction is $7,722.
A percentage is defined.A percentage is mathematics is a figure or number that is stated as a proportion of 100. The abbreviations "pct.," "pct," and "pc" are also occasionally used. However, the symbol "%" used to denote it is frequently used. The percentage amount is flat; there are no dimensions. Given that their numerator is 100, percentages are basically fractions.
Here,
According to the clauses 1/10, n/30, the buyer would receive a 1% reduction if the discount was applied within 10 days.
The consumer would be required to pay the whole amount in 30 days if the payment was not completed within this time frame.
Considering this and the fact that Nieman invoiced $2,400 for the returned goods, you must deduct this sum from their original purchase:
=> $12,200-$2,400= $7,800
Then, you must figure out the discount at 1% of $7,800 and deduct it from $7,800:
=> $7,800*1%= $78
=> $7,800-$78= $7,722
This means that, in the event Nieman Company settles the invoice during in the buy the product, the sum of money needed to complete the transaction is $7,722.

The prove that the given expression is divisible by 43 is explained below.
Divisibility of numbers.A number is said to be divisible by a given number when it leaves no remainder after the division. Example; show that 7^7 is divisible by 49.
7^7 = 823543
So that;
823543/ 49 = 16807
To prove that the expression is divisible by 43, we have;
7^8 = 5764801
7^7 = 823543
7^6 = 117649
Then,
7^8 - 7^7 + 7^6 = 5764801 - 823543 + 117649
= 4941258 + 117649
= 5058907

What is the Probability.
The value of the conditional Probability is P(A|B) is 1/3.
What is probability ?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
The main distinction between a probability and a conditional probability is that a probability is the likelihood of an event, such as A, occurring, whereas a conditional probability assumes that another event, such as B, has already happened in order to define the probability of an event, such as in the conditional probability of A given B.
Conditional probability is the likelihood that any event A will occur in the presence of another event B that is related to A. P(A|B) illustrates it.
By, Conditional Probability :
P (A∩B) =P (A∩B') - P(B)= 4/9 - 1/3 = 1/9
P(A|B) = P (A∩B)/ P(B)
= (1/9)/(1/3) = 1/3

What is the distance between (4,-2), (0,4)
Answer:
the distance between (4,-2) and (0,4) is √(52) or approximately 7.2 units.
Step-by-step explanation:
To find the distance between two points in a Cartesian coordinate plane, we can use the distance formula:
distance = √((x2-x1)² + (y2-y1)²)
In this case, the two points are (4,-2) and (0,4). So,
x1 = 4, y1 = -2 and x2 = 0, y2 = 4
By substituting these values in the distance formula, we get:
distance = √((0-4)² + (4-(-2))²)
distance = √((-4)² + 6²)
distance = √(16 + 36)
distance = √(52)
So the distance between (4,-2) and (0,4) is √(52) or approximately 7.2 units.
Fill in the P(X=x) values in the table below give a legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6.
The legitimate probability distribution for the discrete random variable X whose possible values are 0, 3, 4, 5 and 6 is: P(X=0) = 0.2, P(X=3) = 0.2, P(X=4) = 0.3, P(X=5) = 0.2, and P(X=6) = 0.1.
For a probability distribution to be legitimate, the probabilities of all the possible values of a random variable need to add up to 1. So, in this case, the sum of all the probabilities must be equal to 1.
For the given values, we can assign the probability of 0.2 to the values 0 and 3, 0.3 to the value 4 and 0.1 to the value 6, so that the sum of all the probabilities is 1.
Therefore, the legitimate probability distribution for the given discrete random variable X is as follows:
| Value (x) | P(X=x) |
|---|---|
| 0 | 0.2 |
| 3 | 0.2 |
| 4 | 0.3 |

What is graph?In mathematics, the graph of a function f is the set of ordered pairs, where {\displaystyle f(x)=y.} In the common case where x and f(x) are real numbers, these pairs are Cartesian coordinates of points in two-dimensional space and thus form a subset of this plane.
here, we have,
f(x)=logx
How to determine the equation of g(x)?
From the graph, the given parameters are:
f(x) = log(x)
From the graph, we can see that:
The graph of f(x) is translated left by 1 unit
The graph of f(x) is translated up by 4 units
This transformation is given as
g(x) = f(x + 1) + 4
Mathematically, this transformation can be represented as
(x, y) = (x + 1, y + 4)
When represented as a function, we have
g(x) = f(x + 1) + 4
Substitute the equation f(x) = log(x)
f(x + 1) = log(x + 1) + 4

A student decides to finance a used car over a 5-yr (60-month) period. After making a down
payment of $2000, the remaining cost of the car including tax and interest is $14,820. The
amount owed y = A(t) (in $) is given by A(t) = 14,820-247t, where t is the number of
months after purchase and 0 ≤t≤ 60. Determine the t-intercept and y-intercept and interpret
their meanings in context.
Answer:The t-intercept of a function is the point at which the function crosses the t-axis. To find the t-intercept of the function A(t) = 14,820 - 247t, we need to find the value of t when A(t) = 0. Setting A(t) = 0 and solving for t, we get:
14,820 - 247t = 0
t = (14820/247)
The t-intercept of the function is 60 months, which means that after 60 months (or 5 years) the amount owed on the car will be $0.
The y-interval of a function is the point at which the function crosses the y-axis. To find the y-intercept of the function A(t) = 14,820 - 247t, we need to find the value of A(t) when t = 0.
At t = 0, A(t) = 14,820 - 247(0) = 14,820.
The y-intercept of the function is $14,820 which means that before making the first payment, the cost of the car including tax and interest is $14,820.
Step-by-step explanation:
A is the set of integers greater than -9 and less than -2
B = {a, i, j, y}
(a) Find the cardinalities of A and B.
n(A) =
n (B) = 4
Answer:
n(A) = 6
n(B) = 4
Step-by-step explanation:
The integers greater than -9 but less than -2 are
-8, -7, -6, -5, -4, -3
There are 6 integers and the set A = {-8, -7, -6, -5, -4, -3}
Cardinality of a set is the number of elements in that set
n(A) = 6
n(B) = 4 since there are 4 elements - this seems to have been answered
