(15X-3)
Step-by-step explanation:
Let the number be x.
Tim thought of a number X, multiplied it by 15, and then subtracted 3.
It means, the number will be :
(15X-3)

George Martin loves The Beatles. Honestly, who doesn’t? On George’s favorite Spotify playlist, 40% of the songs are by The Beatles. During a long road trip, George shuffled his playlist and listened to 30 songs. What is the probability that at least half of the songs on the trip were by The Beatles? Don’t forget to check appropriate conditions before you do your computations. Note: you can assume the playlist is infinite in length.
Answer:
17.5%
Step-by-step explanation:
First of all, see this situation as a cumulative binomial distribution. You have isolated trials with a probability of success. This makes it binomial. The wording of the question "what is the probability of at least half..." makes this cumulative.
There are a few ways to calculate this, and I'm not quite sure which way you're familiar with. I'll show the cumbersome way and use wolfram to make the calculation.
First, I'll calculate the probability for 15 success, given 30 trials.
30c15*0.4^15*0.6^15
Since the question asks for the probability of at least 15 success, I'll have to make a calculation for the probability of 16 successes, then 17, and so on. Then I'll have to add all the probabilities together. So, I'll use wolfram for that (see attached)

Answer:
It loses -0.04 milliliters per minute.
Step-by-step explanation:
The pipe loses 1 1/5 milliliters (I'mma just call it ml from now on) every 30 minutes. The question is asking how many ml it loses every one minute. To find this, divide 1 1/5 ml by 30. This is very difficult with fractions tho, so convert the fraction into a decimal. (1 1/5 as a decimal is 1.2) Then divide 1.2 by 30 and you get -0.04 ml per minute.
Make sure you put that it loses *negative* 0.04 ml per minute!

Question 1
What value of v makes the
equation true?
5(5 + 5v) =-29 + 7v
Answer:
v = -3
Step-by-step explanation:
5 (5 + 5v) = -29 + 7v
or, 25 + 25 v = -29 + 7v
or, 25 + 29 = 7v - 25 v
or, 54 = - 18v
or, v = -54/18
or, v = -3
for checking ( putting the value of v in both sides )
5( 5 + 5 (-3))= -29 + 7 (-3)
or, 5 ( 5 - 15 ) = -29 -21
or, 5 (-10) = -50
or, -50 = - 50
the equation is true
hope it will help you ☺✌
Answer:
v = - 3
Step-by-step explanation:
Given
5(5 + 5v) = - 29 + 7v ← distribute parenthesis on left side
25 + 25v = - 29 + 7v ( subtract 7v from both sides )
25 + 18v = - 29 ( subtract 25 from both sides )
18v = - 54 ( divide both sides by 18 )
v = - 3

80% of 90 is the same as 8/9 of 90. true or false
20% of 90 is the same as 1/5 of 90. true or false
Answer:
Both true
Step-by-step explanation: 80%*90=72. 72/90=8/9.
20%*90=18. 18/90=1/5
80% of 90 is the same as 8/9 of 90 is false.
20% of 90 is the same as 1/5 of 90 is true.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, 80% of 90 is the same as 8/9 of 90.
80% of 90 is,
= (80/100)×90.
= 8×9.
= 72.
And,
(8/9)×90.
= 8×10.
= 80.
So, 80% of 90 and 8/9 of 90 is not the same.
20% of 90 is the same as 1/5 of 90.
(20/100)×90.
= 2×9.
= 18.
And,
(1/5)×90.
= 18.
So, 20% of 90 is the same as 1/5 of 90.

b. increase operational capital with a bank loan
c. lower fixed expenses (phone, electric, advertising)
d. lower direct costs (labor, purchasing, controlling, inventory)
Answer:
b
Step-by-step explanation:
increase operational capital with a bank loan
Increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.
What are Expenses?An expense is an item requiring an outflow of money, or any form of fortune in general, to another person or group as payment for an item, service, or other category of costs.
In the article from BusinessTown.com, the author recommends several strategies to lower the break-even point of a business, which is the point where total revenue equals total expenses. The lower the break-even point, the easier it is for a business to make a profit.
Increase operational capital with a bank loan is not a recommendation to lower the break-even point.
Instead, it suggests borrowing more money to finance operations, which can increase the break-even point and the amount of revenue needed to cover expenses.
Hence, increase operational capital with a bank loan is not a recommendation the author of the Businesstown.com article makes to lower your break-even point.
