A colony of 50 bacteria double in size every 30 minutes. What will the population be 120 mintues from now?

Answers

Answer 1

Answer:

800 bacteria

Step-by-step explanation:

Over here, we have exponential growth.

So we have 50 bacteria

Every 30 minutes, it doubles in size

In 120 minutes, there are four 30 minutes.

So you do 50 * 2 * 2 * 2 * 2

Do that out and you get 800

you need 3 sticks of butter for every 24 cookies you bake how many sticks of butter do you need for 16 cookies

Answers

Answer: 2

Step-by-step explanation:

24 divided by 3 is 8 so 1 stick of butter makes 8 cookies so 2 sticks of butter make 16 cookies(2 x 8)

Answer:

2 sticks of butter

Step-by-step explanation:

First, let's figure out how many cookies you can make with one stick of butter. So, we can divide 3 by 3 and 24 by 3...

[tex]\frac{3}{3} = 1\[/tex]

[tex]\frac{24}{3} = 8[/tex]

Now that we know that 1 stick of butter makes 8 cookies, we can multiply the amount of cookies till it becomes 16...

8×? = 16

We could rewrite this equation as division...

16÷8 = 2 sticks of butter

Now we know that we need 2 sticks of butter for 16 cookies...

Hope this Helps!!!

The product of 3 and a number equals the sum of 16 and a number.

Answers

Answer:

The numbers can be either -8,-7,-6, or 6, 7, 8.

n(n−1)(n+1)=16(n−1+n+n+1)  

⟹n(n2−1)=16×3n  

⟹n(n2−1)n=48nn  

⟹(n2−1)−48=48−48  

⟹n2−49=0  

⟶(n−7)(n+7)=0  

n  can be  7  or  −7 , so the numbers can be either  −8,−7,−6

Kate went to the store and bought some pants for $22 and 4 shirts. She spent a total of $52. How much did each shirt cost? Write an equation to represent this situation.

Answers

Answer:

$7.5

$22 + 4x = 52

Step-by-step explanation:

Given that:

Cost of pants = $22

Number of shirts = 4

Total spent = $52

Let the cost per shirt = x

Cost of pants + cost of shirts = total

$22 + 4x = 52

4x = 52 - 22

4x = 30

x = 30 / 4

x = 7.5

Cost per shirt = $7.5

You invest $125,000 in an account that earns 4.75% annual
interest, compounded continuously.
a. What is the value of the account after 15 years?

Answers

Step-by-step explanation:

step 1. let's call the amount of money A, the initial amount A¡, the rate r, and the time t.

step 2. A = A¡e^(rt) (continuously compounding equation)

step 3. A = 125000e^((.0475)(15))

step 4. A = $254,885.32

The value of the account after 15 years will be $254885.


What is compound interest?

In theory, continuously compounded interest means that an account balance is constantly earning interest and reinvesting that interest so that it, too, earns interest.p explanation.

In finance and economics, interest is the payment of an amount above the repayment of the principal sum by a borrower or deposit-taking financial institution to a lender or depositor at a specific rate by a borrower or depositor.

Given that you invest $125,000 in an account that earns 4.75% annually for 15 years of the time.

The compound interest will be calculated as:-

[tex]P(t) = P_o\times e^{rt}\\P(t) = 1250000\times e^{0.0475\times 15}[/tex]

P(t) = $254885

Hence, the value of the account after 15 years will be $254885.

Answers

Answer:

The x-intercept is where the graph crosses the x-axis, so in this case, the x-intercepts are (-4, 0) and (-2, 0).

The y-intercept is where the graph crosses the y-axis, so in this case, the y-intercept is (0,8).

The  line of symmetry splits the  graph in two equal halves, and it is x=-3.

Finally, because this graph opens up, the graph is positive.

If a fair die is rolled 7 times, what is the probability, rounded to the nearest thousandth, of getting at most 2 twos?

Answers

Answer:

0.904

Step-by-step explanation:

Using the binomial distribution, it is found that there is a 0.905 = 90.5% probability of getting at most 2 twos.

For each time the die is rolled, there are only two possible outcomes, either the result is a 2, or it is not. The result on a roll is independent of any other roll, which means that the binomial distribution is used to solve this question.

Binomial probability distribution

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

The parameters are:

x is the number of successes. n is the number of trials. p is the probability of a success on a single trial.

In this problem:

The die is rolled 7 times, hence [tex]n = 7[/tex].One out of the 6 sides is a 2, hence [tex]p = \frac{1}{6} = 0.1667[/tex]

The probability is:

[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2)[/tex]

Hence:

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 0) = C_{7,0}.(0.1667)^{0}.(0.8333)^{7} = 0.279[/tex]

[tex]P(X = 1) = C_{7,1}.(0.1667)^{1}.(0.8333)^{6} = 0.391[/tex]

[tex]P(X = 2) = C_{7,2}.(0.1667)^{2}.(0.8333)^{5} = 0.235[/tex]

Then:

[tex]P(X \leq 2) = P(X = 0) + P(X = 1) + P(X = 2) = 0.279 + 0.391 + 0.235 = 0.905[/tex]

0.905 = 90.5% probability of getting at most 2 twos.
