Answer: 3.75

Step-by-step explanation:

P=0.50, n=15

np= 0.5x15 gives 7.5

n(1-p)= 15x(1-0.5)=7.5

Both are greater than 5

Then Mean, u=np;15x0.5=7.5

Standard deviation, √np(1-p)

15x0.5(0.5)= 3.75

step 1: find the mean by adding up all the numbers and divide the sum by the number of numbers. 
step 2: find the difference between each number and the mean, square the difference
step 3: add up all the results of step 2, divide the sum by (n-1), n is the number of numbers.
step 4:  square root the result of step 3.

it is a long process.

A meteor crater is 3900 feet in diameter. Approximate the distance around the crater. Use 3.14 for pi.
AveGali [126]

"<em>The distance around a circle"</em> = Circumference

Circumference = 3.14 * diameter

3900 * 3.14 = 12246

The circumference (distance around the crater) is equal to 12,246 feet

A country in South America exported 62% of the 315,000 bags of coffee beans they produced in a given year. How many bags did the
Arte-miy333 [17]

Answer:

195,300

Step-by-step explanation:

62 percent *315000 =

(62:100)*315000 =

(62*315000):100 =

19530000:100 = 195300

Now we have: 62 percent of 315000 = 195300

Question: What is 62 percent of 315000?

Percentage solution with steps:

Step 1: Our output value is 315000.

Step 2: We represent the unknown value with x.

Step 3: From step 1 above,315000=100%.

Step 4: Similarly, x=62%.

Step 5: This results in a pair of simple equations:

315000=100%(1).

x=62%(2).

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

315000/x = 100/62%

Step 7: Again, the reciprocal of both sides gives

x/315000 = 62/100

x=195300

Therefore, 62% of 315000 is 195300
