Please help fast! Rosa's friend Jake claims that he can read minds. To test Jake's abilities, Rosa chooses 3 different numbers
grigory [225]

Jake's guesses are illustrations of probabilities.

The probability that Jake's guesses are correct is 1/720

The sample size is:

\mathbf{n = 10} --- 10 different numbers

The probability that Jake's guesses are correct is as follows:

  • 1st guess = 1/10
  • 2nd guess = 1/9
  • 3rd guess = 1/8

So, the required probability is:

\mathbf{Pr = \frac{1}{10} \times \frac 19 \times \frac 18}

\mathbf{Pr = \frac{1}{720} }

Hence, the probability that Jake's guesses are correct is 1/720

Solve please<br> A. 1/6m-3=-5<br> B. 2/3x-3=1/2x-7<br> C. x+x/2-4=x/4
AysviL [449]

Answer:

A m = 48

B x = -24

C x = 16

Step-by-step explanation:

A. 1/6m - 3 = 5

1/6m = 5+3

1/6m = 8

multiply both side by 6

m = 8×6

m = 48

B. 2/3x-3 = 1/2 x-7

2/3 x - 1/2 x = -7 +3

1/6 x = -4

multiply 6 to the both side

x = -4×6

x= -24

C.x+x/2-4= x/4

x+x/2 - x/4 = 4

x + l/2 x - 1/4 x = 4

1/4 x = 4

multiply both side by 4

x= 4×4

x = 16

sweet [91]
\bf \qquad \textit{Amount for Exponential Decay}\\\\&#10;A=P(1 - r)^t\qquad &#10;\begin{cases}&#10;A=\textit{accumulated amount}\\&#10;P=\textit{initial amount}\to &12500\\&#10;r=rate\to 9\%\to \frac{9}{100}\to &0.09\\&#10;t=\textit{elapsed time}\\&#10;\end{cases}&#10;\\\\\\&#10;A=12500(1-0.09)^t\implies A=12500(0.91)^t&#10;\\\\\\&#10;\textit{after 5 years t = 5}\qquad A=12500(0.91)^5

and surely you know how much that is.

Anastaziya [24]
No, because when you set them up side by side, and cross multiply they dont equal the same amount on each side
