Three tenths is bigger then one fourth
Marina CMI [18]3 years ago

Yes, three-tenths is bigger than one-fourth because the common denominator is 20 and three-tenths are equivalent to six-twentieths and one-fourth is equivalent to 5 twentieths.

Sophia spent 6,207 rand on her trip. She exchanged the rand she had left for U.S. dollars. The exchange rate was 1 rand to $0.12
Maru [420]
You divide 6,207 by.12. Which is 50,225. So you would have that many US dollars.

Kristen invests $5,000 in a bank. The bank pays 6.45% interest compounded semi-annually. How much money will she have after 2 ye
kupik [55]

Answer:  $5,676.87

Step-by-step explanation:

Hi, to answer this question we have to apply the compounded interest formula:  

A = P (1 + r/n) nt  

Where:  

A = Future value of investment (principal + interest)  

P = Principal Amount  

r = Nominal Interest Rate (decimal form, 6.45/100= 0.0645)  

n= number of compounding periods in each year (2)  

Replacing with the values given  

A = 5,000 (1+ 0.0645/2)^ (2x2)

A = 5,000 (1.03225)^4

A = $5,676.87

A circle has an area of 144pie square feet what is the diameter of the circle
sukhopar [10]

Answer:

13

Step-by-step explanation:

144 = pie radio square

144 divided by pie = 45.83662361

45.83662361 square root = 6.770275003

6.770275003 multiply by 2 =  13.54055001

13.54055001 = diameter

The random variable X represents the number of test is a patient entering a hospital have along with the corresponding possibili
Galina-37 [17]

Complete question :

The random variable x represents the number of tests that a patient entering a hospital will have along with the corresponding probabilities. Find the mean and standard deviation.

x 0 1 2 3 4

P(x) 3/17 5/17 6/17 2/17 1/17

Answer:

1.59 ; 1.09

Step-by-step explanation:

The Mean :

E(X) = Σx*p(x)

(0*3/17) + (1 * 5/17) + (2*6/17) + (3*2/17) + (4*1/17)

= 1.58823

= 1.59

Standard deviation = sqrt(Var(x))

Var(X) = Σx²*p(x) - E(x)²

= {(0^2*3/17) + (1^2 * 5/17) + (2^2*6/17) + (3^2*2/17) + (4^2*1/17)} - 1.59^2

= 3.7058823 - 2.5281

= 1.1777823

Standard deviation = sqrt(1.1777823)

= 1.0852567

= 1.09

Dose the infinite geometric series diverge or converge? explain 3+9+27+81
tamaranim1 [39]
The terms will be 3, 9, 27, 81 and so on.

notice, to get the next term, we simply multiply the current one by 3, namely the "common ratio" r = 3.

to make it plain and short, if 0 < | r | < 1, then the series sum will diverge, namely is approaching an explicit value, instead of just going on and on to infinity.

0 < | r | < 1, namely, if the common ratio is between 0 and 1, well a fraction, either negative or positive, only then the serie sum will diverge.  In this case is 3 and 3 is definitely not a fraction in that range.
