Answer:

305 and 793

Step-by-step explanation:

LCM * HCF = product

3965 * 61 = 241,865 = 5*13*61*61

HCF = 61 so

61*5 = 305

61 * 13 = 793

seraphim [82]

Answer:

8 / 9 miles

Step-by-step explanation:

Given that:

Jason's distance = 1/3 mile

Jane's distance = 2/6 miles

Jude's distance = 2/9 miles

The total miles rowed down the river by all 3 :

(1/3 + 2/6 + 2/9) miles

The L. C. M of the denominator (3, 6, 9) = 18

(6 + 6 + 4) / 18

16 / 18 miles

8 / 9 miles

2. Suppose that a particular medical procedure has a cost that is approximately normally distributed with a mean of $19,800 and

Lina20 [59]

Answer:

a) 0.5085

b) -1.6551

c) 0.8103834

Step-by-step explanation:

Data provided in the question:

Mean = $19,800

Standard deviation, s = $2,900

Now,

z score = [ X - Mean ] ÷ s

a) The procedure costs between $18,000 and $22,000

For X = $22,000

z-score = [ $22,000 - $19,800 ] ÷ $2,900

= 0.7586

For X = $18,000

z-score = [ $18,000 - $19,800 ] ÷ $2,900

= -0.62069

P(procedure costs between $18,000 and $22,000)

= P(z < 0.7586) - P( z < -0.62069)

= 0.7759541 - 0.2674018 [ P value from standard z table ]

= 0.5085

b) The procedure costs less than $15,000

For X = $15,000

z-score = [ $15,000 - $19,800 ] ÷ $2,900

= -1.6551

thus,

The procedure costs less than $15,000

P (z < -1.655172 )

= 0.0489448 [ P value from standard z table ]

c) The procedure costs more than $17,250

z-score = [ $17,250 - $19,800 ] ÷ $2,900

= -0.87931

thus,

The procedure costs more than $17,250.

P (z > -0.87931 ) = 0.8103834

Vedavit walks his dog the same distance each day. After 5 days, he has walked his dog 1 mile. How many feet does he walk his dog

posledela

Answer:

$1056 ft$

Step-by-step explanation:

''Vedavit walks his dog the same distance each day.''

After 5 days,he has walked his dog 1 mile.''

First we are going to convert the total distance (1 mi) to feet.

The relation is :

$1mi=5280 ft$

After 5 days, he has walked his dog 5280 ft.

The next step is to divide the total distance for the amount of day that he has walked his dog (we do this because Vedavit walks his dog the same distance each day)

$\frac{5280ft}{5 days} =1056\frac{ft}{day}$

Finally, he has walked his dog $1056 ft$ each day
