Answer:  The required probability that Maria will wear blue dress at her party is 16.67%.

Step-by-step explanation:  Given that Maria has three red dresses, two white dresses and one blue dress.

We are to find the probability that Maria will wear a blue dress at her party.

Let S denotes the sample space of selecting a dress from the collection of Maria and A be the event that Maria wear blue dress at her party.

Then, we have

n(S)=3+2+1=6,\\\\n(A)=1.

Therefore, the probability of event A is given by

P(A)=\dfrac{n(A)}{n(S)}=\dfrac{1}{6}=\dfrac{1}{6}\times100\%=16.67\%.

Thus, the required probability that Maria will wear blue dress at her party is 16.67%.

£40 is divided between Jim, Krutika &amp; Natasha so that Jim gets twice as much as Krutika, and Krutika gets three times as muc
harkovskaia [24]

Answer:Jim gets £24

Step-by-step explanation:

Let the amount Natasha gets be represented as x

SO that Krutika getting  three times as much as Natasha be represented as 3x

AND Jim getting  twice as much as Krutika  be represented as 2 x 3x=6x

The equation to show how much each gets can be represented as

x + 3x  +6x=40

Solving

x +3x + 6x=40

10x =40

x =40/10 =4

Natasha gets £4

Krutika gets 3x =3x4= £12

Jim gets 6x=6 x4= £24

Use the formula s=32, 512(1.10)^t to calculate your salary after 2 years. Round your answer to the nearest dollar.
Amiraneli [1.4K]

<em><u>Answer:</u></em>

s = $39,340

<em><u>Explanation:</u></em>

Note: I will use the symbol "n" instead of "t" in the solution.

<u>The given formula is:</u>

s = 32,512 * (1.1)ⁿ where "n" is the number of years.

We want to get the salary after 2 years. This means that we will substitute with n = 2 in the above equation and get the value of s.

<u>This is shown as follows:</u>

s = 32,512 * (1.1)²

s = $39,339.52 which is approximately $39,340

Hope this helps :)
