Taylor opened a savings account with $425. After 2 years, the total interest earned was $10.20. What was the annual interest rat

storchak [24]

Answer:

R = 1.2%

Step-by-step explanation:

<u>Given the following data;</u>

Principal = 425

Time = 2

Simple interest = 10.20

To find the annual interest rate;

Mathematically, simple interest is calculated using this formula;

$S.I = \frac {PRT}{100}$

Where;

S.I is simple interest.
P is the principal.
R is the interest rate.
T is the time.

Substituting into the equation, we have;

$10.20 = \frac {425*R*2}{100}$

$10.20 = \frac {850R}{100}$

Cross-multiplying, we have;

$1020 = 850R$

$R = \frac {1020}{850}$

<em>Therefore, the annual interest rate is 1.2 percent. </em>

Carlos uses a vertical number line to graph the points −4, −2, 3, and 4. He notices that −4 is closer to zero than −2. He is not

aivan3 [116]

Step-by-step explanation:

The number line is a line with marks, where each mark represents a real number.

In the vertical number line zero is in the center. The numbers above zero are considered positive and the numbers below zero are considered negative.

-1

-2

-3

-4

The numbers after zero start from 0, 1, 2 ...... and 0, -1, -2.....

Hence, Carlos is wrong and -4 is further to zero than -2

An exam consists of 50 multiple choice questions. Based on how much you studied, for

Ann [662]

Using the Central Limit Theorem, it is found that the sampling distribution of the sample proportion of the 50 questions on which you get the correct is approximately normal, with mean of 0.7 and standard error of 0.0648.

<h3>What does the Central Limit Theorem state?</h3>

It states that for a proportion p in a sample of size n, the sampling distribution of sample proportion is approximately normal with mean $\mu = p$ and standard deviation $s = \sqrt{\frac{p(1 - p)}{n}}$ , as long as $np \geq 10$ and $n(1 - p) \geq 10$ .
