Answer:
The time taken is 4.79 minutes.
Step-by-step explanation:
[tex]P = Po(1.4)^{t}[/tex]
initial Population, Po = 400
Final population, P = 2000
Let the time is t.
[tex]2000 = 400(1.4)^{t} \\5 = (1.4)^t\\log 5 = t log 1.4\\0.6989 = 0.146 t \\t = 4.79 minutes[/tex]

Samantha saw two bottles of ketchup at the store for the same price. One bottle contained 4 pints of ketchup, and the other contained 1.25 quarts of ketchup.
Which bottle was the better bargain?
Answer:
The 4 pint ketchup bottle was the better bargain.
Step-by-step explanation:
To find which bottle was the better bargain, find which one had the most amount of ketchup in it.
In one quart, there are 2 pints.
Convert the 1.25 quart bottle to pints by multiplying 1.25 by 2:
1.25(2)
= 2.5
Since 4 is larger than 2.5, the 4 pint bottle of ketchup has more.
So, the 4 pint ketchup bottle was the better bargain.
There is 1/3 of a pizza left to split between 3 of your friends. If you split the pizza equally. What fraction of the pizza will each of your friends get.
Answer:
Each friend will get 1/9 of the pizza (I think).
Step-by-step explanation:
I believe you would divide 1/3 by 3, or in other words, multiply 1/3 * 1/3:
1/3 * 1/3 = 1/9

I WILL GIVE BRAINLIEST!!!!!!! A video game developer wants to know how long it takes people to finish playing their new game. They surveyed a random sample of 13 players and asked how long it took them (in minutes). 1.235 952 457 1,486 1,486 | 1,759 1,148 548 1,0371,864 | 1,245 866 1,431 a. Estimate the median time it will take all players to finish this game. minutes b. Find the interquartile range for this sample minutes
Answer:
a) median = 1,148 minutes
b) IQR = 549.5
Step-by-step explanation:
Q1 = (952 + 866) / 2 = 909
Q3 = (1431 + 1486) / 2 = 1458.5
IQR = 1458.5 - 909.0 = 549.5

stay safe healthy and happy.Jasmine had an average daily balance of $1,608.24 for the last billing cycle, which had 31 days. If her credit cards charges an APR of 22.99%, what would her finance charges be for the last billing cycle?
Answer:
Finance per billing cycle = $ 30.91
Step-by-step explanation:
First, we will calculate the APR for 1 day:
APR per day = (22.99%/year)(1 year/12 month)(1 month/31 days)
APR per day = 0.062 % / day
Now, we will calculate the finance per day:
Finance per day = (Daily Balance)(APR per day) = ($ 1608.24)(0.062 %/day)
Finance per day = $0.99/day
Now, we will calculate the finance for one billing cycle:
Finance per billing cycle = (Finance per day)(31 days) = ($ 0.99/ day)(31 days)
Finance per billing cycle = $ 30.91
Using the Pythagorean theorem what is the distance between (5,-3) and (9,1)
Step-by-step explanation:
Distance between (5,-3) and (9,1)=√(9-5)^2+(1-(-3))^2
=√4^2+4^2
=√16+16
=√32 units
It's not possible to calculate the distance between these points by pythagoras theorem .We can easily calculate it by distance formula I.e.√(x2-x1)^2+(y2-y2)^2
Find the value of x.
Answer:
x = 4
Step-by-step explanation:
The angle next to (adjacent to) 19x + 3 is 180 degrees less (19x + 3):
180 - (19x + 3)
and the three interior angles of the triangle must sum up to 180 degrees:
11x - 2 + 180 - 19x - 3 + 9x + 1 = 180, or
11x - 2 - 19x - 3 + 9x + 1 = 0
Combining like terms, we get:
x = 4
Suppose A and B are independent events. If P(A) = 0.6 and P(B) = 0.85, what is P(A and B)? A. .34 B. .51 C. .17 D. .68
Answer:
0.51
Step-by-step explanation:
Mathematically, for two individual events;
P(AnB) = P(A) * P(B)
P(A n B) = 0.6 * 0.85 = 0.51
Answer:
.51 (B)
