____ [38]

Answer:

The mean is 4.88 hours / day

Step-by-step explanation:

To calculate the mean we just add the values and divide by the number of items (in this case we add the hours and divide by the number of days)

so the equation would be

\frac{1.7+7.7+8.3+1.6+5.1}{5}=4.88

mars1129 [50]

Answer:

The absolute change in the height of the water is 9.5 inches

Step-by-step explanation:

Given

l =24in --- length

w = 15in --- width

h =12in --- height

V_1 = 900in^3 --- the volume removed

Required

The absolute change in the height of the water

First, calculate the base area (b):

b = l * w

b =24in * 15in

b =360in^2

The height of the water that was removed is:

<em />H = \frac{V_1}{b}<em> i.e. the volume of the water removed divided by the base area</em>

H = \frac{900in^3}{360in^2}

H = \frac{900in}{360}

H = 2.5in

The absolute change in height is:

\triangle H = |h - H|

\triangle H = |12in - 2.5in|

\triangle H = |9.5in|

\triangle H = 9.5in

Find two consecutive odd integers such that 65 more than the lesser is four times the greate
lyudmila [28]
Let the lesser number be x  and y the greater. Then

x + 65 = 4y ,  Also

y - x =  2
Adding:-

y + 65 = 4y + 2
63 = 3y
y = 21
and
x = 21-2 = 19

Answer the 2 odd numbers are 19 and 21.
