$91.14
Step-by-step explanation:
11.76 (7) = 82.32
11.75 (.75) = 8.82
Answer:
C. 72 million
Step-by-step explanation:
Put the appropriate value of x into the correct formula and do the arithmetic.
... For the year 2002, x = 2002 -1980 = 22.
Then the population estimate is ...
... h(22) = 51.42 +15.473·log(22)
... = 51.42 +15.473·1.3424
... = 51.42 +20.77
... = 72.19 ≈ 72 . . . . million . . . . . matches choice C.
Answer:
The highest score is 32.
Step-by-step explanation:
We are given the following in the question:
The mean score of 8 players is 14.5.
Let x denote the highest score.
If x is removed, the mean of the score of the remaining 7 players is 12.
Formula for mean:
Putting values, we get:
Thus, the highest score is 32.
Here we have a case of the least common multipl(lcm) of 6 and 20.
Prime numbers 2,3,5,7,11,13,17,19... (natural numbers greater than 1 that has no positive divisors other than 1 and itself) .
lcm(6,20)= 6 20 | 2
3 10 | 3
1 10 | 2
5 | 5
1
2*3*2*5=60 The first one to get both calendar and the animal toy will be 60th.
Explenation: First we look for the smallest prime number with wich 6 and 20 can be devided by. That is 2. Next is 3. Since 10 is not divisible by 3, we only copy it. Under the 6 we got 1, wich is our goal. Now we continue to devide 10 by prime numbers till we also get 1. We now multiple all divisors and we get the least common multiple.
