the mean of 10 numbers is 1445. if 1500 is also added to this data what will be there new mean of 11 numbers

tamaranim1 [39]

Let the sum of the 10 numbers be x, then
x/ 10 = 1445
x = 1445 x 10 = 14450

New mean = (14450 + 1500)/11 = 15950/11 = 1450

The equation y = 50(1.05)x models the growth of a mule deer population introduced into Guadalupe National Park in December 2015.

Vesna [10]

9514 1404 393

Answer:

J. 2085

Step-by-step explanation:

Fill in the desired value for y and solve for x.

1500 = 50(1.05^x)

30 = 1.05^x . . . . . . . divide by 50

log(30) = x·log(1.05) . . . . . take logarithms

x = log(30)/log(1.05) ≈ 69.71

Since x represents years after December 2015, x = 69.7 will be some time in mid 2085.

Elle placed a bucket under a leaky roof. The bucket was 310 full after 25 of an hour. How much water is leaking per hour?

kvasek [131]

Answer:

3/4 bucket

Step-by-step explanation:

Elle placed a bucket under a leaky roof. The bucket was 3/10 full after 2/5 of an hour. How much water is leaking per hour

Water leaking : time taken

Let x = amount of water leaking per hour

3/10 : 2/5 = x : 1

3/10 ÷ 2/5 = x / 1

3/10 × 5/2 = x / 1

15 / 20 = x / 1

Cross product

15 * 1 = 20 * x

15 = 20x

x = 15/20

= 3/4

3/4 bucket of water is leaking per hour
