If the principal is $350 and the interest rate is 3 percent, what is the simple interest earned in one year?simple interest = Pxrxt

Answers

Answer 1

Answer:

Answer:

The simple interest was found to be $9.6 after 1 year at 3%

Step-by-step explanation:

Given that

principal p= $350

rate r= 3%= 3/100= 0.03

time t= 1 year

The expression for the simple interest is given as

SI= p*r*t

SI= 320*0.03*1

SI= $9.6

After 1 year at 3% the simple interest is $9.6

Simply put the extra money earned after an investment is called the simple interest

Central limit theorem Imagine that you are doing an exhaustive study on the children in all of the elementary schools in your school district. You are particularly interested in how much time children spend doing active play on weekends. You find that for this population of 2,431 children, the average number of minutes spent doing active play on weekends is μ = 87.85, with a standard deviation of σ = 118.1. You select a random sample of 25 children of elementary school age in this same school district.

Annisa wrote an expression that represents“the product of 6.2 and the sum of 3c and 8.”
What are the factors of the expression?

Answers

Answer:

“the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:

⇒ (6.2) (3c + 8)

We know that the numbers that we multiply are the factors of the product.

Here, (6.2) and (3c+8) are the factors of the expression.

Step-by-step explanation:

Let us breakdown and translate the word expression into an algebraic expression.

The sum of 3c and 8 is algebraically represented as:

⇒ 3c + 8

Thus, “the product of 6.2 and the sum of 3c and 8'' will be algebraically represented as:

⇒ (6.2) (3c + 8)

We know that the numbers that we multiply are the factors of the product.

Here, (6.2) and (3c+8) are the factors of the expression.

Consider a disease whose presence can be identified by carrying out a blood test. Let p denote the probability that a randomly selected individual has the disease. Suppose n individuals are independently selected for testing. One way to proceed is to carry out a separate test on each of the n blood samples. A potentially more economical approach, group testing, was introduced during World War II to identify syphilitic men among army inductees. First, take a part of each blood sample, combine these specimens, and carry out a single test. If no one has the disease, the result will be negative, and only the one test is required. If at least one individual is diseased, the test on the combined sample will yield a positive result, in which case the n individual tests are then carried out. [The article "Random Multiple-Access Communication and Group Testing"† applied these ideas to a communication system in which the dichotomy was active/idle user rather than diseased/nondiseased.] If p = 0.15 and n = 5, what is the expected number of tests using this procedure? (Round your answer to three decimal places.)

Answers

Answer:

The expected number of tests, E(X) = 6.00

Step-by-step explanation:

Let us denote the number of tests required by X.

In the case of 5 individuals, the possible value of x are 1, if no one has the disease, and 6, if at least one person has the disease.

To find the probability that no one has the disease, we will consider the fact that the selection is independent. Thus, only one test is necessary.

Case 1: P(X=1) = [P (not infected)]⁵

= (0.15 - 0.1)⁵

P(X=1) = 3.125*10⁻⁷

Case 2: P(X=6) = 1- P(X=1)

= 1 - (1 - 0.1)⁵

P(X=6) = (1 - 3.125*10⁻⁷) = 0.999999

P(X=6) = 1.0

We can then use the previously determined values to compute the expected number of tests.

E(X) = ∑x.P(X=x)

= (1).(3.125*10⁻⁷) + 6.(1.0)

E(X) = E(X) = 6.00

Therefore, the expected number of tests, E(X) = 6.00

Linda is paid double her normal hourly rate for each hour she works over 40 hours in a week. Last week she worked 52 hours and earned $544. What is her hourly rate? Equation = (use h as variable)
Weekly Rate = $

Answers

Answer:

$837.96

got u bro good luck

Step-by-step explanation:

Final answer:

By setting up an equation based on her hourly work and pay, we find that Linda's hourly rate of pay is $8.5 per hour.

Explanation:

To answer this question, we need to set up an equation based on the information provided. We know that Linda earns a normal hourly rate for her first 40 hours and twice that for the hours she works over 40. The total money she made is $544.

If we define h as her hourly rate, then for the first 40 hours, she earns 40h dollars. For the extra hours (in this case 12), she earns double her normal rate, meaning she earns an additional 2h*12 dollars. Setting up the equation gives us:

40h+2h*12 = 544

Solving this equation will give us the value of h, which is her hourly rate. 40h+24h=544, simplifying this will result in 64h=544. So her hourly rate is 544/64 = $8.5.

What is the distance between -34 and 16

Answers

The distance between -34 and 16 as requested is; 50

The distance between two points, x and y on the number line is the absolute value of their difference.

Distance = | x -y |

In this scenario; the distance between -34 and 16 is therefore;

Distance = | -34 - 16|

Distance = | -50 |

In essence, Distance = 50.
