Answer:

P(1 and 2) = 1/16

Step-by-step explanation:

There is a 1/4 chance of selecting the correct answer to the 1st question as there is a 1/4 chance of selecting the correct answer to the 2nd question. Since both events are independent, their probabilities are multiplied. Therefore, the probability that Jacqueline will select the correct answer for problems 1 and 2 is (1/4)(1/4)=1/16

What is the answer to<br> -2a-9=6a+15
timurjin [86]

Answer:

a=-3

Step-by-step explanation:

-2a-9=6a+15

Add 9 to both sides:

-2a-9+9=6a+15+9

-2a=6a+24

Subtract 6a from both sides:

-2a-6a=6a+24-6a

-8a=24

Divide both sides by -8:

\frac{-8a}{-8}=\frac{24}{-8}

a=-3

Someone please help
KIM [24]

Answer:

Step-by-step explanation:

Exponential function representing final amount with compound interest compounded continuously,

A=Pe^{rt}

Here, A = Final amount

P = principal amount

r = Rate of interest

t = Duration of investment

For P = $9600

r = 6%

A = 2 × 9600 = $19200

By substituting these values in the formula,

19200=9600(e)^{0.06\times t}

2=e^{0.06t}

ln(2)=ln(e^{0.06t})

ln(2) = 0.06t

t = \frac{0.693147}{0.06}

t = 11.55245

t ≈ 11.5525 years

Any amount will get doubled (with the same rate of interest and duration of investment) in the same time.

Therefore, $960000 will get doubled in 11.5525 years.
