Answer:

Interest earned after 5 years is $1100.

Step-by-step explanation:

We know that,

i=\dfrac{Prt}{100}

where,

i = interest

P = principal = $5500

r = rate of interest = 4%

t = time period = 5 years

Putting the values,

i=\dfrac{5500\times 4\times 5}{100}

=\dfrac{110000}{100}

=\$1100

Therefore, the interest earned after 5 years is $1100.

Find the probability of each event.

Using the binomial distribution, it is found that there is a 0.0108 = 1.08% probability of the coin landing tails up at least nine times.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

In this problem:

  • The coin is fair, hence p = 0.5.
  • The coin is tossed 10 times, hence n = 10.

The probability that is lands tails up at least nine times is given by:

P(X \geq 9) = P(X = 9) + P(X = 10)

In which:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 9) = C_{10,9}.(0.5)^{9}.(0.5)^{1} = 0.0098

P(X = 10) = C_{10,10}.(0.5)^{10}.(0.5)^{0} = 0.001

Hence:

P(X \geq 9) = P(X = 9) + P(X = 10) = 0.0098 + 0.001 = 0.0108

0.0108 = 1.08% probability of the coin landing tails up at least nine times.

Which graph shows the solution to the equation below? log Subscript 3 Baseline (x + 3) = log Subscript 0.3 (x minus 1) On a coor
Effectus [21]

Answer:

On a coordinate plane, 2 curves intersect at (1, 1). One curve curves up and to the right from quadrant 3 into quadrant 1. The other curve curves down from quadrant 1 into quadrant 4

Step-by-step explanation:

The first function is given as:

log_3(x+3)

The second function is given as:

log_{0.3}(x-1)

First we graph both the functions.

We can see that one curves up and to the right from quadrant 3 into quadrant 1. This curve is of  log_3(x+3)

The other curve curves down from quadrant 1 into quadrant 3

Both curves interest almost at (1,1)

See the graph attached below

Blue line represents first function

Green line represents second function

The solution lies on the Red line.

A number cube has sides numbered 1 through 6. The probability of rolling a 2 is 16
ser-zykov [4K]
Hello there.

<span>A number cube has sides numbered 1 through 6. The probability of rolling a 2 is 16
what is the probability of not rolling a 2?

Answer: I'm guessing that by 16 you meant 1/6. Therefore you do 6/6 - 1/6 = 5/6,
Therefore the answer is 5/6.

Hope This Helps You!
