Li invest money in a savings account. She wants to know the amount of simple interest that she will earn 6 years at 3.75 percent

What additional information does she needs to find this amount
Mathematics
1 answer:
Sloan [31]4 years ago
4 0

Answer:

<h2>Principal</h2>

Step-by-step explanation:

In Business, the formula for calculating simple interest on an amount of money saved is expressed using the formula below.

Simple Interest = Principal * Rate * Time/100

From the question, the parameters given are the time which is 5 years and the rate at 3.75%. There is no information on the principal and <u>before we can calculate the simple interest that Li will earn, the her principal must be made known</u>. Principal is like the amount she initially saved in her account.

<em>Hence, </em><em>the additional information that she needs</em><em> to find the simple interest </em><em>is her principal.</em>

A gas can hold 10 L of gas. How many cans could we fill with 7 L of gas?
katrin2010 [14]

Answer: It is only one can that can be filled up.

Step-by-step explanation: If 1 gas can can hold 10 L of gas and you only have 7 L then how can you fill up more than 1 gas can with only 7 L?  You don't have enough gas to fill up more than 1 gas can. So you are left with only 1 gas can filled but only with 7 L.

A resident of Bayport claims to the City Council that the proportion of Westside residents
Kazeer [188]

Answer:

The test statistics is  z =  -1.56  

The p-value is   p-value =  0.05938

Step-by-step explanation:

From the question we are told  

   The West side sample  size is n_1  =  578

    The  number of residents on the West side with income below poverty level is k  = 76

    The East side sample size  n_2=688

  The  number of residents on the East side with income below poverty level is u  = 112

   The null hypothesis is  H_o  :  p_1 = p_2

    The alternative hypothesis is  H_a :  p_1 <  p_2

Generally the sample proportion of  West side is  

     \^{p} _1 = \frac{k}{n_1}

=>   \^{p} _1 = \frac{76}{578}

=>   \^{p} _1 =  0.1315

Generally the sample proportion of  West side is  

     \^{p} _2 = \frac{u}{n_2}

=>   \^{p} _2 = \frac{112}{688}

=>   \^{p} _2 =  0.1628

 Generally the pooled sample proportion is mathematically represented as

    p = \frac{k + u}{ n_1 + n_2 }

=>  p = \frac{76 + 112}{ 578 + 688 }

=>  p =0.1485

Generally the test statistics is mathematically represented as

z = \frac{\^ {p}_1 - \^{p}_2}{\sqrt{p(1- p) [\frac{1}{n_1 } + \frac{1}{n_2}  ]}  }

=> z = \frac{ 0.1315  - 0.1628 }{\sqrt{0.1485(1-0.1485) [\frac{1}{578} + \frac{1}{688}  ]}  }  

=> z =  -1.56  

Generally the p-value  is mathematically represented as

          p-value =  P(z <  -1.56 )

From z-table  

         P(z <  -1.56 ) =  0.05938

So

     p-value =  0.05938

If f(x) = 2x + 3, what is f(–1)?
Helen [10]

Answer:

Normally, sequences don't go behind 1, but let's see for this one.

f(-1) = 1

Step-by-step explanation:

Let's sub for -1 in x.

f(-1) = 2(-1) + 3.

f(-1) = -2 + 3

f(-1) = 1
