A bacteria colony doubles every 40 minutes. If the colony contains 10 bacteria at noon, how many bacteria are present at 6 pm?
A.180
B.512
C.810
D.900
E.5120
Answer: E
noon to 6 pm is 6 hours which is 360 minutes
divide 360 by 40 to get the number of times it doubles which is 9 times so it’ll be 2 to the ninth power (2 is there since your doubling the number of bacteria)
multiply that by 10 since that was how many bacteria there was at the beginning
10 x 2^9 = 5120
5120 bacteria will be there at 6 PM.
This question is an example of geometric progression, in which a bacteria colony has growing population that is multiplying itself at constant rate. The geometric progression is defined by this expression:
[tex]n (t) = n_{o} \cdot r^{\frac{t}{\tau} }[/tex] (1)
Where:
[tex]n_{o}[/tex] - Initial population, no unit.[tex]r[/tex] - Growth rate, no unit.[tex]t[/tex] - Time, in minutes.[tex]\tau[/tex] - Time factor, in minutes.If we know that [tex]n_{o} = 10[/tex], [tex]r = 2[/tex], [tex]\tau = 40\,min[/tex] and [tex]t = 360\,min[/tex], then the population of bacteria at 6 PM is:
[tex]n(360) = 10\cdot 2^{\frac{360}{40} }[/tex]
[tex]n (360) = 5120[/tex]
5120 bacteria will be there at 6 PM.

The probability that it will be warmer today than it was yesterday is 0.1.
The probability that it will be colder today than it was yesterday is 0.7.
a .What is the probability that it will not be colder today than it was yesterday?
b What is the probability that it will not be warmer today than it was yesterday?
Answer:
a) 30% probability that it will not be colder today than it was yesterday
b) 90% probability that it will not be warmer today than it was yesterday
Step-by-step explanation:
In this question, we have that:
0.1 = 10% probability it will be warmer today than yesterday.
0.7 = 70% probability it will be colder today than yesterday.
a .What is the probability that it will not be colder today than it was yesterday?
70% probability it will be colder, so 100 - 70 = 30% probability that it will not be colder today than it was yesterday.
b What is the probability that it will not be warmer today than it was yesterday?
10% probability it will be warmer today than yesterday, so 100 - 10 = 90% probability that it will not be warmer today than it was yesterday

Estimate 58.311+49.35 by first rounding each number to the nearest whole number.
Answer:
≈107
Step-by-step explanation:
58.311 will round down since 0.311 is less than half or 0.5. It will become 58. 49.35 will also round down since 0.35 is less than 0.5. This will be 49. 58+49=107. Since 107 is not the exact answer, you will use the approximately sign, or ≈.

A corner store sells two kinds of baked goods: cakes and pies. A cake costs $7 and a pie costs $6. In one day, the store sold 10 baked goods for a total of $66. What system would work for the situation?
9514 1404 393
Answer:
c + p = 107c + 6p = 66Step-by-step explanation:
Assuming you're interested in the number of each that were sold, the system of equations will express the relation for total sold, and the relation for total revenue. We have used the variable c and p to represent numbers of cakes and pies sold, respectively. Your choices may use x and y, instead.
c + p = 107c + 6p = 66__
The solution can be found by subtracting 6 times the first equation from the second. That tells you 6 cakes were sold, hence 4 pies.
You pull a marble from a bag with 20 red 20 white and 10 green marbles. You hold onto it and then pull another marble. What is the probability of pulling a red marble and then pulling a green marble?
The probability of pulling a red marble and then pulling a green marble is,
⇒ 3 / 5
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
We have to given that;
You pull a marble from a bag with 20 red 20 white and 10 green marbles.
Here, Total number of marbles = 20 + 20 + 10
= 50
Thus, The probability of pulling a red marble is,
⇒ 20 / 50
⇒ 2 / 5
And, The probability of pulling a green marble is,
⇒ 10 / 50
⇒ 1 / 5
Therefore, The probability of pulling a red marble and then pulling a green marble is,
⇒ 2 / 5 + 1 / 5
⇒ 3 / 5

$600 invested at 5% compounded daily after a period of 3 years.
Answer:
$697.09
Step-by-step explanation:
The computation of the investment after 3 years is shown below:
As we know that
Amount = Present value × (1 + rate)^number of years
= $600 × (1 + 0.05 ÷ 365)^365× 3
= $697.09
Hence, the investment after 3 years is $697.09
We simply used the above formula to determine the investment

Ball thrown straight up
H(x)=64x-16xSquared
How do you find the value of x when the ball reached its maximum height.
Answer:
x = 2
Step-by-step explanation:
H(x) = 64x - 16x²
Find the value of x when the ball reaches its maximum height.
Since the largest degree in this equation is two, this function represents a parabola. We can find the maximum height of the ball at the vertex of the quadratic.
In H(x) = 64x - 16x², rearrange the powers from greatest to least:
a = -16b = 64c = 0Vertex: [-b/2a, f(-b/2a)]
Substitute a and b into the x-value of the vertex: -b/2a.
-(64)/2·(-16) -64/-32 2The vertex of the parabola is at x = 2, with a maximum height of H(2).
On rainy weekend days, the probability that Karen bakes bread is
90%. On the weekend, the probability of rain is 50%. There is a 29%
chance that today is a weekend day. What is the probability that today
is a rainy weekend day in which Karen is baking bread?
9514 1404 393
Answer:
13%
Step-by-step explanation:
The probability is the product of the individual probabilities.
p(baking | rainy weekend) = 0.90
p(rainy weekend) = p(rain | weekend) × p(weekend) = 0.50×0.29 = 0.145
Then ...
p(baking) = p(baking | rainy weekend) × p(rainy weekend) =
0.90 × 0.145 = 0.1305 ≈ 13%
