First find the multiplier: 5.5% + 1 = 1.0505.

Then we do amount x (multiplier) to the power of how many years.

300 x (1.0505)^5

The answer is <span>383.79696707. 

We round this to 2dp, making it £393.80

REMEMBER UNITS!!!

C+ax=dx<br><br><br>this one has all variables and no numbers
sergeinik [125]
That's OK, but you have not said which variable you want to solve it for.

<u>To solve for 'x':</u>
                                           <span>c + ax = dx

Subtract c from each side:    ax = dx - c

Subtract  dx  from each side:   ax - dx = -c

Factor the left side:                 x (a - d) = -c

Divide each side by (a - d) :      x = -c / (a - d)  or  <u>x = c / (d - a)</u> .

The amount of time it takes Evelyn to go grocery shopping is continuous and uniformly distributed between 20 minutes and 44 minu
vivado [14]

Answer:

85.71% probability that it takes Evelyn less than 38 minutes given that it takes less than 41 minutes for her to go grocery shopping

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

P(X < x) = \frac{x - a}{b-a}

Uniformly distributed between 20 minutes and 44 minutes.

This means that a = 20, b = 44.

What is the probability that it takes Evelyn less than 38 minutes given that it takes less than 41 minutes for her to go grocery shopping

We know that it takes less than 41 minutes, so we can update b to 41.

So

P(X < 38) = \frac{38 - 20}{41 - 20} = 0.8571

85.71% probability that it takes Evelyn less than 38 minutes given that it takes less than 41 minutes for her to go grocery shopping
