Answer:
$34,341
Step-by-step explanation:
Given :
Job Salary Percent of Employees Entry 23,264 60% 47,480 38% 117,027 2%
To obtain the best value for the mean salary ; we obtain the weighted average ;
Σ(salary * weight factor) / Σ weight
[(23264 * 0.60) + (47480 * 0.38) + (117027 * 0.02)] ÷ (0.60 + 0.38 + 0.02)
= 34341.34 / 1
Average salary = 34341.34
= $34,341 ( nearest dollar)
2.975 round up to 3.
2.975 rounded up to the nearest hundredths is 2.98
2.975 rounded up to the neared tenths will automatically be 3. because 0.97 rounded up to the neared tenths will result to 1.0.
2.975 rounded up to the nearest ones is 3.
Any number that must be rounded to the nearest place must be aware of the number next to it. If the following number is 5 and up, the number place is rounded up. If the next number is 4 and below, the number place is rounded down.
Answer:
C.
Step-by-step explanation:
We estimate that 12/480=1/40 fish are tagged, so 600 is 1/40 of the total number of fish. This means that there are about 600*40=24000 fish total in the pond.
Answer:
3x^2 +8x -10=-8
Step-by-step explanation:
A quadratic equation is
ax^2 + bx +c=0
has a formula
-b ± sqrt( b^2 -4ac)
--------------------------
2a
We know a = 3 b = 8 and c = -2
3x^2 +8x -2=0
Subtract 8 from each side
3x^2 +8x -2 -8=0-8
3x^2 +8x -10=-8
That is choice C
