Kate bad $2,251 in here bank account. Currently, she has $1,958 in her account. What is the approximate percent of decrease in h

Fiesta28 [93]

Answer:

The answer is: 13%.

Step-by-step explanation:

At first, Kate had $2,251. Then her new balance was $1,958. The difference between the two is the amount spent:

$2,251 - $1,958 = $293.

The difference is the ratio of the amount spent divided by the original amount, to provide the decrease:

$293 / $2,251 = .13 or 13% (Approximately)

Hope this helps! Have a great day!

Is x =4 a solution of the equation 13=2x + 4? A.yes B.no

Harman [31]

No, it is not. If you plug 4 into the equation in the place of x, you get 13=2(4)+4

13=8+4

13=12

It equals 12, not 13.

Tina wants to save money for school. Tina invests $1,100 in an account that pays an interest rate of 7.25%. How many years will

svlad2 [7]

The amount of Tina money can be expressed in an exponent function like this:
an= $1100(1.0725)^n
The variable an represent the total money and variable n is the years needed to achieve that amount.

Then, the time needed for the money to reach $6,600 would be:

an= $1100(1.0725)^n
$6,600= $1100(1.0725)^n
$1,100(6)= $1100(1.0725)^n
6= (1.0725)^n
n= log1.075 6
n= 24.78

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 3 minutes and 15 minute

madam [21]

Answer:

33.33% probability that it takes Isabella more than 11 minutes to wait for the bus

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X lower than x is given by the following formula.

$P(X \leq x) = \frac{x - a}{b-a}$

For this problem, we have that:

Uniformly distributed between 3 minutes and 15 minutes:

So $a = 3, b = 15$

What is the probability that it takes Isabella more than 11 minutes to wait for the bus?

Either she has to wait 11 or less minutes for the bus, or she has to wait more than 11 minutes. The sum of these probabilities is 1. So

$P(X \leq 11) + P(X > 11) = 1$

We want P(X > 11). So

$P(X > 11) = 1 - P(X \leq 11) = 1 - \frac{11 - 3}{15 - 3} = 0.3333$

33.33% probability that it takes Isabella more than 11 minutes to wait for the bus
