Answer: x= - 14

Step-by-step explanation:

4(x + 2) = 3(x - 2)

4x+8 = 3x-6

-3x -3x

x+8 = -6

-8 = -8

x = -14

Answer:

x = -14

Step-by-step explanation:

Step 1: Write equation

4(x + 2) = 3(x - 2)

Step 2: Solve for x

Distribute: 4x + 8 = 3x - 6
Subtract 3x on both sides: x + 8 = -6
Subtract 8 on both sides: x = -14

Step 3: Check

Plug in x to verify it's a solution.

4(-14 + 2) = 3(-14 - 2)

4(-12) = 3(-16)

-48 = -48

A tennis player makes a successful first serve 51% of the time. If she serves 9 times, what is the probability that she gets exa

aleksley [76]

Answer:

$P(X=3)$

And we can use the probability mas function and we got:

$P(X=3)=(9C3)(0.51)^3 (1-0.51)^{9-3}=0.1542$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=9, p=0.51)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want this probability:

$P(X=3)$

And we can use the probability mas function and we got:

$P(X=3)=(9C3)(0.51)^3 (1-0.51)^{9-3}=0.1542$

Terri invested $1500 in an account with an interest rate of 2.25% compounded continuously. How long will it take for Teri’s acco

melomori [17]

Answer:

53.51 years

Step-by-step explanation:

FV = PV e⁽ⁿˣ⁾

FV = Future Value = $5000

PV = Present Value = $1500

n = Interest Rate = 2.25%

x = time in years = ?

e = mathematical constant = 2.7183

So,

5000 = 1500 e⁽⁰°⁰⁰²⁵ˣ⁾

50 / 15 = e⁽⁰°⁰⁰²⁵ˣ⁾

㏑ (3.3333) = 0.0225x ㏑ (2.7183)

1.2040 = 0.0225x

x = 53.51 year

So, If compounded continuously at an APR of 2.25% the amount invested in an account of $1500 will accumulate to $5000 in 53.51 years.
