Answer:

216 gallon

Step-by-step explanation:

We are given that

Milk in gallon  probability   week

200                   3/30            3

205                   4/30            4

210                   6/30           6

215                    5/30          5

220                    4/30          4

225                    3/30          3

230                     2/30          2

235                     2/30         2

240                     1/30         1

Total weeks=30

We have to find the average number of gallons of milk  consumed per week

The average number of gallons of milk  consumed per week

=Total number of gallons of milk/total weeks

Using the formula

The average number of gallons of milk  consumed per week

=\frac{200(3)+205(4)+210(6)+215(5)+220(4)+225(3)+230(2)+235(2)+240(1)}{30}

=\frac{6480}{30}

=216gallons/week

Hence, the average number of gallons of milk  consumed per week= 216 gallon

Problem 1 [4 pts]: The maintenance cost of machines are uniformly distributed from 0 to 160 (dollars). If a random sample of 75
Andru [333]

Answer:

$6,000

Step-by-step explanation:

The mean value of a sample is assumed to be the same as the mean of the population. The mean of a uniformly distributed variable between 0 and 160 is:

M = \frac{0+160}{2}\\ M=\$80

If the mean cost for each machine is $80, the mean aggregate cost for a sample of 75 machines is:

M_{75}=75*\$80\\M_{75}=\$6,000

The mean aggregate maintenance cost is $6,000.

How many subsets are there of the set N = {1, 42, 65, 12, 31, 27}?
lutik1710 [3]

Answer:

\boxed{ \bold{  \huge{ \boxed{ \sf{64}}}}}

Step-by-step explanation:

If ' n ' is the cardinal number of a set, the number of subsets of a given set can be obtained by using the formula 2ⁿ

Given,

N = { 1 , 42 , 65 , 12 , 31 , 27 }

where n ( total number of elements ) = 6

So, the number of possible subsets of set N :

= 2ⁿ

= 2⁶

= 2 × 2 × 2 × 2 × 2 × 2

= 64

Hope I helped!

Best regards!!
