Meg initially has 3 hours of pop music and 2 hours of classical music in her collection. Every month onwards, the hours of pop m

zlopas [31]

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Number of hours of pop music = 3

Number of hours of classical music = 2

According to question, Every month onwards, the hours of pop music in her collection is 5% more than what she had the previous month. Her classical music does not change.

Rate of increment = 5% = 0.05

Let the number of months be 'x'.

So, our required function becomes,

$f(x)=3(1+0.05)x+2\\\\f(x)=3(1.05)x+2$

Hence, Option 'd' is correct.

Shankar has decided to train to be a Carbucks Barrista. Being young and inexperienced, for every order he makes a mistake in mak

astra-53 [7]

Answer:

Step-by-step explanation:

Since each trial is independent of the other

no of mistakes he does is binomial with p = 1/3

a) the probability that he makes no mistakes on his first 10 orders but the 11th order is a mistake

= $(\frac{2}{3}) ^{10} *\frac{1}{3}\\=\frac{2^{10} }{3^{11} }$

b) Prob that shanker quits = P(Shankar does I one mistake and Fran does not do the first one)+Prob (Shanker does mistake in the II one while Fran does both right)

= $\frac{1*5}{3*6} +\frac{2}{3} \frac{1}{3}(\frac{5}{6})^2 =\frac{5}{18} +\frac{50}{216} \\=\frac{55}{108}$

Fraz is running a science fair experiment where mice run through a maze with 4 turns. At each turn, the mouse can take a right o

kherson [118]

Answer:

the probability is 0.125

Step-by-step explanation:

The number of ways in which the mouse can move in the 4 turns is calculated using the rule of multiplication as:

2 * 2 * 2 * 2 = 16

1st turn 2nd turn 3rd turn 4th turn

Because the mouse can take two options at every turn, right or left.

Now, from the 16 possibilities of movements, a mouse will find an exit in just two options:

1. right-right-left-left

2. left-right-right-left

So, the probability that a mouse will find an exit is:

$P=\frac{2}{16}=0.125$

Because, there are 16 possibilities and a mouse will find an exit using 2 of them.
