Answer:
$2561.50
Step-by-step explanation:
If the account earns simple interest, then the balance at the end of 6 months will be ...
... A = P + Prt . . . . . for principal amount P, interest rate r, time period t
... A = $2350 +2350·0.18·6/12 = $2350 + 211.50
... A = $2561.50
If a company has five employees with annual salaries of $60,000, $70,000, $60,000, $90,000, and $80,000, respectively, what is t
Vanyuwa [196]
well to find the mean you add up all the numbers then divide by the ammount of numbers so it would be 60,000+70,000+60,000+90,000+80,000=360,000 then you divide that by 5 and you end up with 72,000
To find the value of a variable you must know the basics of pre-Algebra.
Example:
2x+9=39
To find he answer of this you must subtract 9 from both sides
Then you are left with…
2x=30
Since 2x=30 means 2 times x equals 30
You can divide 2 from both sides to find the answer
Which is…
x=15
Answer:
True
True
Step-by-step explanation:
The unknown parameters are treated as variable and data serve as coefficients. The random variables are value whose outcome depends on some random event. The θ can exist when n ≥ 0. A sample mean is a sequence which has normal distribution and n ≥ 1. The sample average of X-n follows normal distribution for all integer and n is greater or equal to 1.
Answer:
40 ways
Step-by-step explanation:
Step one:
given data
number of people= 6
number of committees=6
Required
The number of ways the committees can be formed differently
Step two:
Applying the combination formula we have
C(n,r)= n!/(n-r)r!
substitute
C(n,r)= 6!/(6-3)3!
C(n,r)= 6*5*4*3!/3*3!
C(n,r)= 6*5*4/3
C(n,r)= 120
/3
C(n,r)= 40 ways
