The manager must check relative frequencies by row because there are more than two different promotions. The manager must check relative frequencies by column because there are more than two different promotions. The manager cannot use relative frequencies to look for an association because there are more than two different promotions. The manager should check both relative frequencies by row and by column to look for an association.

or wy not? Please explain.
Answers
Yes, to some extent President Biden is right in telling them to lower the price rate because due to the war, a lot of gas companies a using it as a yardstick to inflate their prices and sell above the normal rate they bought it and the oil firms needs to consider the times that people are too.

Answers
The one making the most money in one week is by sales manager which is an amount of $1006.25.
What is Unit Rate?Unit rate is the amount of one quantity for a unit amount of the other quantity.
Given that,
Hourly rate of a head mechanic = $37.52 per hour
Number of hours worked in a week = 25 hours
Money made = 25 × 37.52 = $938

Number of hours worked in a week = 30 hours
Money made = 30 × 30.42 = $912.6
Hourly rate of a sales manager = $28.75 per hour
Number of hours worked in a week = 35 hours
Money made = 35 × 28.75 = $1006.25
Hourly rate of a front desk clerk = $15.09 per hour

Draw an angle in standard position with the given measure. 8/3 π
Answers
The asterisk (*) represents the vertex of the angle, the initial side is the positive x-axis, and the terminal side is the red line segment that forms an angle of 8/3 π with the positive x-axis.
What is the standard position of angles?
Standard position simply means that the vertex of the angle is at the origin of the circle and that one ray of the angle is on the positive x-axis. The other ray of the angle is placed at the angle measure formed by traveling counter-clockwise along the circle.
To draw an angle in standard position with measure 8/3 π, follow these steps:
Start with the positive x-axis.
Counterclockwise, rotate the initial side of the angle until it coincides with the positive x-axis.
Starting from the initial side on the positive x-axis, rotate the terminal side of the angle in a counterclockwise direction until the angle measures 8/3 π.
The resulting angle will have a measure of 8/3 π and will look like the following:

In a classroom, 100 plastic fish are in a tub. The tub is hidden from the student view. Some fish are green, and the rest are yellow. The students know that there are 100 fish, but they don’t know how many of each color there are. The students go fishing, each time, picking a random fish from the tub, recording its color, and throwing the fish back in the tub. At the end of the day, 65 fish have been chosen, 12, green and 53 yellow. What is the best estimate you can give for the number of green fish in the number of yellow fish in the tub? Describe how to calculate this best estimate, and explain why your method of calculation makes sense in a way that a seventh grader my understand. Is your best estimate necessarily accurate? Why or why not?
Answers
The best estimate for the number of fish is that there are 82 yellow fish and 18 green fish, which you can calculate using the rule of three. This estimate is expected to be accurate.
What is the estimated number of fish of each color?This can be calculated using a rule of three as follows. Let's start with the yellow fish:
53 = 65
x = 100
53 x 100 / 65 = 82 yellow fish
Green fish:
12 = 65
x = 100
12 x 100 / 65= 18 green fish
Is this estimate accurate?This estimate is expected to be accurate; however, there might be small differences in real life such as 80 yellow fish and 20 green fish.

of the account after 8 years?
Answers
If principal is $2,658 and rate of interest 9% then the value of the account balance is approximately $10,253 by using continuous compound interest formula.
What is the Continuous Compound Interest ?Recurring interest is interest calculated on principal plus all interest and other interest. The idea is that lenders always receive interest, not individually at specific times.
The formula for continuous compound interest :
A= Peˣⁿ
Where,
A =Amount of money after a certain amount of time
P= principal or the amount of money you start with
e =Napier's number, which is approximately 2.7183
x =Interest rate
n =Amount of time in years.
Use the continuous compound interest formula :
Given P= 2658
x =9% = = 0.09
n = 15
e = 2.7183
By using
A= Peˣⁿ
A= (2658)(2.7183)⁰°⁰⁹¹⁵
A =10,253 (approximately)
Hence, the value of account balance after 15 years is approximately $10,253

x=3
Explanation:
First what you do is move x to one side and the rest of the numbers to another while changing the sign from + to - or - to + like this
6x+4x= 1+-21+50
Then you do the equation on 1 side
6x+4x=30
And then the other but add them like x is not there
10x=30
Your final result should be
X=3
Answer:
x = 3
Step-by-step explanation:
First you want to add the numbers.
6x - 1 + 4x + 21 = 50
6x + 20 + 4x = 50
Then you want to combine like terms
6x + 20 + 4x = 50
10x + 20 = 50
Then subtract 20 from BOTH sides of the equation
10x + 20 = 50
10x + 20 - 20 = 50 - 20
After, simplify.
10x = 30
Then divide BOTH sides of the equation by the same term
10x / 10 = 30 / 10
Simplify ..
x = 3

The equation that models the relationship between the number of guests, x, and the total charge, y is A. y = 450 + 125x. The base charge for a single guest is $450, and for each additional guest, the charge increases by $125. So, we add 125 times the number of additional guests to the base charge of $450.
