The price of a new slide in stove is $794. Pedro makes a 10% down payment for a
two-year installment purchase. The monthly payment is $34.25 dollars. What is his
down payment?
Answer:
$79.4
Step-by-step explanation:
Given that :
Price of stove =$794
Down payment = 10% =
Time = 2 years = 24 months
Monthly payment = $34.25
Down payment = 10% of 794
Down payment = 0.1 * $794
Down payment = $79.4
Hence, down-payment = $79. 4
John worked in a furniture store for a salary of $850 a month, plus a commission of 6% on sales over $20,000. How much did he earn in a month where he sold $36,000 worth of furniture?v
Answer:
He earned in this month $1810
Step-by-step explanation:
∵ John worked in a furniture store for a salary of $850 a month
∴ His fixed salary = $850
∵ He takes a commission of 6% on sales over $20,000
∴ His commission = 6% on sales over $20,000
→ Change it to decimal by divide it by 100
∴ His commission = [tex]\frac{6}{100}[/tex] = 0.06 on sales over $2000
∵ In one month he sold $36,000 worth of furniture
∴ He will take a commission on the value that over $20,000
∵ The amount of selling over $20,000 = 36,000 - 20,000
∴ The amount of selling over $20,000 = $16,000
→ Multiply it by 0.06 to find his commission
∵ His commission = 0.06 × 16,000
∴ His commission = $960
→ Now let us find his total earn
∵ His total earn = his salary + his commission
∴ His total earn = 850 + 960 = 1810
∴ He earned in this month $1810

Identify which shapes on the graph are congruent to shape l by preforming these sequences of transformations on shape l:
▪︎ A reflection across the y-axis, followed by a 90ﾟcounterclockwise rotation about the origin, and then are translation 3 units down
▪︎ A 90ﾟcounterclockwise rotation about the origin in their translation 2 units up and units left
▪︎ 180° rotation about the origin and then a translation 1 unit right
Answer:
Your awnsers would be C and B
Step-by-step explanation:
The 2 number shape which is 90ﾟcounterclockwise rotation about the origin and 180° rotation about the origin.
What are transformations?
A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.
Given:
After rotation in sequence we will get 2 number shape which is congruent shape.
According to given question we have
A 90ﾟcounterclockwise rotation about the origin : means a right angle about the origin in opposite direction the needle would point to (9=45 mins)the reflection of it would mean the needle is at 3 = 15 min.
180° rotation about the origin : either in the clockwise or counterclockwise direction, each point of the given figure has to be changed from (x, y) to (-x, -y) .
Therefore, the 2 number shape which is 90ﾟcounterclockwise rotation about the origin and 180° rotation about the origin.

A supermarket has been experiencing long lines during peak periods of the day. The problem is noticeably worse on certain days of the week, and the peak periods sometimes differ according to the day of the week. There are usually enough workers on the job to open all cash registers. The problem is knowing when to call some of the workers who are stocking shelves up to the front to work the checkout counters. How might business analytics help the supermarket? What data would be needed to facilitate good decisions?
Answer:
Step-by-step explanation:
As you will have understood, processing this information qualitatively by giving it meaning is essential for understanding the market in which the company is positioned and anticipating its evolution. In this sense, the business analysis contributes to the performance of results.
Why do a business analysis?
Relevant business analysis can exhaustively list and understand the reasons for a sale's success or failure. It facilitates decision-making, the reproduction of a sales performance while constituting a source of motivation for the sales team members in the field.
The role of Business analytics would assist the supermarket in efficiently scheduling their workers. This would help to reduce congestion at the checkout counter and offer customers an improved shopping experience. Thus, the supermarket can exploit its labor resource effectively and efficiently with the assistance of business analytics.
The data needed to facilitate good decisions are:
Number in terms of customers getting to the checkout counters, relating to the day and time of checkout.The minimum regular amount of time customers usually use in the store will assist in planning ahead. Numbers in terms of the customer standing in the queue, if any.The population of workers situated in the store.What is the answer?

Step-by-step explanation:
A company has 2 machines that produce widgets. An older machine produces 23% defective widgets, while the new machine produces only 8% defective widgets. Besides, the new machine produces 3 times as many widgets as the older machine does. Given that a randomly chosen widget was tested and was found to be defective, what is the probability that it was produced by the new machine
Answer:
The value is [tex]P(Z' | N )= 0.92[/tex]
Step-by-step explanation:
From the question we are told that
The proportion of defective widgets produced by older widget is [tex]p = 23\% = 0.23[/tex]
The proportion of defective widgets produced by new widget is
[tex]q = 0.08[/tex]
Generally since we are considering the new machine in this question it then mean that the probability that widget was defective given that it was produce by the new machine is
[tex]P(Z | N ) = 0.08[/tex]
Here Z is the event that the widget was defective
N is the even that the widget was produced by the new machine
Also the probability that the widget was defective given that it was not produced by the new machine is
[tex]P(Z | N') = 0.23[/tex]
Generally from the question the probability that the widget was produced by the new machine is mathematically represented as
[tex]P( N) = \frac{3}{4}[/tex]
=> [tex]P( N) = 0.75[/tex]
Generally the probability that the widget is defective and that it was produced by the new is mathematically represented as
[tex]P( Z\ n \ N) = P(Z | N ) * P(N)[/tex]
=> [tex]P( Z\ n \ N) = 0.08 * 0.75[/tex]
=> [tex]P( Z\ n \ N) = 0.06[/tex]
Generally the probability that the widget is defective and that it was not produced by the new machine is
[tex]P(Z\ n \ N') = P( Z | N' ) * [1 -P(N)][/tex]
=> [tex]P(Z\ n \ N') = 0.23 * [1 -0.75][/tex]
=> [tex]P(Z\ n \ N') =0.0575[/tex]
Generally the probability that the widget is defective is
[tex]P(Z) = P(Z \ n \ N) + P(Z \ n \ N')[/tex]
=> [tex]P(Z) = 0.06 + 0.0575[/tex]
=> [tex]P(Z) = 0.1175[/tex]
Generally the probability that the widget is not defective and it produced by the new machine is mathematically represented as
[tex]P(Z' \ n \ N ) = P(N ) - P(Z \ n \ N)[/tex]
=> [tex]P(Z' \ n \ N ) =0.75 - 0.06[/tex]
=> [tex]P(Z' \ n \ N ) =0.69[/tex]
Generally the probability that the widget was produced by the new machine,given that a randomly chosen widget was tested and was found to be defective is mathematically represented as
[tex]P(Z' | N ) =\frac{P(Z' \ n \ N)}{P(N)}[/tex]
=> [tex]P(Z' | N )= \frac{0.69}{0.75}[/tex]
=> [tex]P(Z' | N )= 0.92[/tex]

A plumber charges his customers $90 for each hour he works. If Mr. Hall's bill for
plumbing services is $855, which equation could be used to determine the number of
hours the plumber worked?
The equation that represents the number of hours the plumber worked is
90(x) = 855.
What is an equation?An equation is written in the form of variables and constants separated by the operation of multiplication and division,
An equation states that terms in different forms on both sides of the equality sign are equal.
Multiplication and division do not separate the terms of an equation.
Given, A plumber charges his customers $90 for each hour he works.
Assuming the no. of hours to be 'x'.
