Answer:
Divide the weight of the bag by 2.
Step-by-step explanation:
Every time we divide the weight of bags by 2 we always get the number of marbles in this situation.
For example, in the first one:
Weight of bag is 20
Number of marbles is 10
20/10 = 2 or 20 / 2 = 10
On bag number 5 the weight is 100 grams (Add 20 every time)
100/2 = 50
The number of marbles in a bag that weighs 100 grams is 50.
50 marbles
Answer:
The expressión is:
10(a+14) = 9a
and the number is:
-140
Step-by-step explanation:
The expression is:
10(a+14) = 9a
then:
10*a + 10*14 = 9a
10a + 140 = 9a
10a - 9a = -140
a = -140
Check:
10(-140+14) = 9*140
10*-126 = 1260
Answer: 2.4
Step-by-step explanation:
Given : A large disaster cleaning company estimates that 30 percent of the jobs it bids on are finished within the bid time.
i..e The proportion of the jobs it bids on are finished within the bid time: p = 30%= 0.30
Sample size of jobs that it has contracted : n= 8
Then , the mean number of jobs completed within the bid time : 
Hence, the mean number of jobs completed within the bid time is 2.4 .
