at a simple annual interest rate of 4.5 percent, haw many years will it take Sam to earn 135 dollars on an original account of 1,000

Answers

9514 1404 393

Answer:

  3

Step-by-step explanation:

The simple interest formula is useful here:

  I = Prt

where I is the interest earned on principal P invested at rate r for t years.

Filling in the given information, we can solve for the unknown.

  135 = 1000·0.045·t

  135/45 = t = 3

It will take 3 years for Sam to earn $135 on his account.

Answers

Answer:

Discrete

Step-by-step explanation:

Given

Number of phone calls between two cities on Thanks giving day

Required

Discrete or Continuous

Number of phone calls can be represented as thus:

0, 1, 2 , 3 , 10, 20, 100 or any other positive whole numbers

Only discrete data take form of the above.

Hence, "Discrete" answers the question

The given random variable is discrete and this can be determined by observing the given data.

Given :

The number of phone calls between New York and California on Thanksgiving day.

The following steps can be used in order to determine the given random variable as being discrete or continuous:

Step 1 - According to the given data, the number of phone calls between New York and California on Thanksgiving day.

Step 2 - So, the total number of calls on thanksgiving day may be 0, 2, 6, 9, 15, 100, 115, or whole positive number.

Step 3 - So, from the above steps, it can be concluded that the given random variable is discrete.

Answer:

Katie spent 29.2 minutes

Step-by-step explanation:

I hope this helps!!!

Answer:

29.2 minutes

Step-by-step explanation:

If Jasmine ran 5 miles in 42 minutes. Katie ran 4 miles.  She ran at a rate that was 1.1 minutes per mile slower than Jasmine.  For how many minutes did Katie run?  Explain how you determined your answer. So basically When you run slower you subtract so  8.4 minus 1.1 is 7.3. And then multiply it by 4 and get 29.2 You can check your answer by dividing 29.2 by 7.3

An article presents a study of the effect of the subbase thickness on the amount of surface deflection caused by aircraft landing on an airport runway. In six applications of a 160 kN load on a runway with a subbase thickness of 864 mm, the average surface deflection was 2.34 mm with a standard deviation of 0.090 mm. Find a 90% confidence interval for the mean deflection caused by a 160 kN load. Round the answers to three decimal places. The 90% confidence interval is ( , ).

Answers

Answer:

The answer is below

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean.

Given that: sample size (n) = 6, standard deviation (σ) = 0.09 mm, mean (μ) = 2.34 mm

The confidence interval = 90% = 0.9

α = 1 - 0.9 = 0.1

α / 2 = 0.05

The z score of 0.05 is the same as the z score of 0.45 (0.5 - 0.05) which is 1.645.

The margin of error is given as:

[tex]E=Z_{\frac{\alpha}{s} }*\frac{\sigma}{\sqrt{n} }[/tex]

[tex]E=1.645*\frac{0.09}{\sqrt{6} }=0.06\ mm[/tex]

The confidence interval = μ ± E = 2.34 ± 0.06 = (2.28, 2.40)

The confidence interval is between 2.28 mm and 2.4 mm

How many grams are in 1.204 x 10 24 atoms lithium

Answers

Answer:

We have:

1.204x10^24 atoms of lithium.

The weight of one atom of lithium is: 6.941 atomic mass units.

And we know that:

1 atomic mass unit = 1.661x10^(-24)g

Then the mass of one atom is 6.941 times 1.661x10^(-24)g

m = 6.941*1.661x10^(-24)g = 1.153x10^(-23)g

Then the mass of 1.204x10^24 atoms is 1.204x10^24 times 1.153x10^(-23)g

M = 1.204x10^24 *1.153x10^(-23)g = 1.388x10^(24 - 23) g

M = 1.388x10^1g = 13.88 g

Then 1.204x10^24 atoms of lithium wieght 13.88 grams.

The sum of two consecutive integers is 26. What are the integers? Question does not specify even or odd consecutive integers. Please HELP!

Answers

X is some integer


X+1 is the consecutive integer
Consecutive interferes are numbers like { 5,6,7 } or { 11,12,13 }. They are numbers that follow after one another

We sum x and x+1 getting 26 which means
x+(x+1)=26

2x+1=26

2x=26-1

2x=25

x=25/2

x=12.5

We made x an internet but 12.5 isn’t a integer so there are no solutions to the first integer equation.
So there are no consecutive integers that add up to 26.

If your teacher said consecutive even integers then your equation would be

x+(x+2)=26

2x+2=26

2x=24

x=24/2

x=12

And we can see that x=12 and x+2=12+2=14 add 12+14=26

Thar only applies if your teacher wrote consecutive even integers. With that even left out there are no solutions
