Bank a charged 45 $ monthly fee with unlimited transaction. Bank b charged 20$ monthly fee plus 0.70for each transaction
Answers
Transactions are larger than others Bank B may be the cheaper option even if you make more than 35 transactions.
To compare the cost of using Bank A and Bank B need to consider the total cost based on the number of transactions.
Let's say you make x transactions in a month.
For Bank A the monthly cost is a fixed fee of $45 regardless of the number of transactions.
For Bank B the monthly cost is a fee of $20 plus $0.70 for each transaction.
So the total cost for Bank B is:
Total cost = $20 + $0.70x
The break-even point where the total cost of Bank A and Bank B are equal need to solve the following equation:
45 = 20 + 0.70x
Subtracting 20 from both sides, we get:
25 = 0.70x
Dividing both sides by 0.70, we get:
x = 35.71
If you make more than 35 transactions in a month Bank A is the cheaper option.
If you make fewer than 35 transactions Bank B is the cheaper option.
Analysis assumes that all transactions are of the same amount.
To compare the total cost of both banks based on the actual amounts of the transactions.

A dairy needs 372 gallons of milk containing 6% butterfat. How many gallons each of milk containing 7% butterfat and milk containing 3% butterfat must be used to obtain the desired 372 gallons?
Answers
We know that we need a total of 372 gallons of milk.
So, x + y = 372
We also know that the final mixture must contain 6% butterfat.
To find the amount of butterfat in the final mixture, we can multiply the percentage of butterfat in each milk by the number of gallons of that milk, add the two amounts of butterfat, and divide by the total number of gallons:
0.07x + 0.03y = 0.06(372)
Now we have two equations with two variables:
x + y = 372
0.07x + 0.03y = 22.32
We can solve for one of the variables in terms of the other in the first equation:
y = 372 - x
We can substitute this expression for y into the second equation:
0.07x + 0.03(372 - x) = 22.32
Simplifying and solving for x:
0.07x + 11.16 - 0.03x = 22.32
0.04x = 11.16
x = 279
So we need 279 gallons of milk containing 7% butterfat and 93 gallons of milk containing 3% butterfat to obtain 372 gallons of milk containing 6% butterfat.
Answer: 279 gallons of milk containing 7% butterfat and 93 gallons of milk containing 3% butterfat.

RQT = 159
RQS = 69
==============================================
Explanation:
Draw a segment connecting R and S.
Triangle SRQ is a right triangle due to Thale's Theorem. That theorem is a special case of the inscribed angle theorem. The 90 degree angle R is opposite the diameter SQ.
Minor arc QR = 42 degrees. Half of this is 42/2 = 21, which is the measure of inscribed angle RSQ. This inscribed angle subtends minor arc QR.
Focus on triangle SRQ. We have two known angles (R = 90 and S = 21). Let's use them to find the missing angle.
The inside angles of any triangle always add to 180 degrees.
S+R+Q = 180
21+90+Q = 180
111+Q = 180
Q = 180-111
Q = 69
Angle RQS is 69 degrees.
----------------
We'll add angle SQT onto the previous result to get angle RQT.
angle RQT = (angle RQS) + (angle RQT)
angle RQT = (69) + (90)
angle RQT = 159 degrees

What is the probability of picking an odd number and then picking an odd number?
Write your answer as a fraction or whole number.
Answers
The probability of picking an odd number and then picking an odd number when two cards are drawn without replacement from a set of four cards labeled 3, 4, 5 and 6 is 1/6 or approximately 1667/10000 .
The probability of picking an odd number and then picking an odd number when two cards are drawn without replacement from a set of four cards labeled 3, 4, 5 and 6 can be found by using conditional probability.
The probability of the first card being odd is 2/4 (since there are two odd numbers out of four cards). If the first card was odd and not replaced, the number of cards remaining is three, with only one odd card. Therefore, the probability of picking an odd number again is 1/3.
So, the probability of picking an odd number and then picking an odd number is the product of the probabilities of picking an odd number in the first draw and picking an odd number in the second draw, given that the first draw resulted in an odd number.
P(Odd, Odd) = P(Odd on the first draw) * P(Odd on the second draw given that the first draw was odd)
P(Odd, Odd) = (2/4) * (1/3)
P(Odd, Odd) = 2/12
P(Odd, Odd) = 1/6 or approximately 0.1667

How to calculate the valuea. slope AB = (k+4-9)/(k+1-0) = (k-5)/(k+1)
The slope of AC is:
slope AC = (k+3-9)/(2k-0) = (k-6)/(2k)
Since A, B, and C are collinear, slope AB = slope AC. Therefore, we have:

< Select an answer <
Do not round in between steps. Round answers to at least 4 decimal places.
Answers
The 95% confidence interval of the mean is approximately (26.4121, 39.3879) lbs.
How to solve for the confidence intervalsince df = n - 1 = 20 - 1 = 19). You can find this value using a t-distribution table or an online calculator.
For a 95% confidence level and 19 degrees of freedom, the t-score is approximately 2.093.
Now, let's calculate the margin of error (E):
E = 2.093 * (14.8 / √20)
E ≈ 6.4879
Finally, we'll find the confidence interval:
Lower Bound = x - E = 32.9 - 6.4879 ≈ 26.4121 lbs
Upper Bound = x + E = 32.9 + 6.4879 ≈ 39.3879 lbs
The 95% confidence interval of the mean is approximately (26.4121, 39.3879) lbs.

There are 16 equally likely outcomes on a spinner, numbered 1 through 16. What are the odds against stopping on a number less than 12?
Answers
The odds against stopping on a number less than 12 is 5 ; 11
How to determine the odds against stopping on a number less than 12?From the question, we have the following parameters that can be used in our computation:
Sections in the spinner = 16
This means that the probability of getting a number less than 12 is
P(Number less than 12) = Sections less than 12/Sections in the spinner
There are 11 sections less than 12
So, we have
P(Number less than 12) = 11/16
When represented as odds, we have
P(Number less than 12) = 16 - 11 : 11
Evaluate the difference
P(Number less than 12) = 5 : 11

Answers
The amount of walking space between two tables at the point where they are the closest is 0.9 m.
We are given that;
The space allowed per chair = 45 cm.
Number of tables=30
Now,
we find the length of a side of a square that contains a table by adding twice the radius of a table to twice the space allowed per chair. The formula is: side length=2×radius+2×space per chair
Plug in the given values and simplify. The calculation is: side length=2×0.9+2×0.45=2.7
Now subtract the diameter of a table from the side length to get the walking space between two tables. The formula is: walking space=side length−diameter
Plug in the given values and simplify. The calculation is: walking space=2.7−1.8=0.9
To express our answer in meters. walking space=0.9 m
Therefore, by the algebra the answer will be 0.9 m.

Fred has a great idea for a new product. However, he can only invest $11,919 to start up the company. He asks a three other
individuals to invest in his company. The other three investors bring the total investment to start the company to $285,763.
What percent of the company does the three other individuals own? Round your answer to the nearest tenth of a percent.
Answers
Answer:
He owns about 4.17% or 4% so the others own about 95.83% or 96% but sense it rounds to the nearest tenth your answer would be 95.8%
Step-by-step explanation:
You can figure this out by doing 11,919 divided by 285,763 in order to figure out the percentage of the company he owns and then just do 100 - your answer.
Step-by-step explanation:
First, we need to find out how much money the three other individuals invested in the company. To do that, we'll subtract Fred's investment from the total investment:
Total investment = 285,763
Fred's investment = 11,919
Investment from the three other individuals = Total investment – Fred's investment
Investment from the three other individuals = 285,763 – 11,919
Investment from the three other individuals = 273,844
Now, to calculate the percentage of ownership for the three individuals, we'll divide their combined investment by the total investment and multiply by 100:
Percentage of ownership = (Investment from the three other individuals / Total investment) * 100
Percentage of ownership = (273,844 / 285,763) * 100
Percentage of ownership ≈ 95.8%
So, the three other individuals own approximately 95.8% of the company. Since the question asks to round to the nearest tenth, the answer is 95.8%.
