Answer:
16,17,18,19
Step-by-step explanation:
one guy guessed. probably using a calculator
another guy took the 4th root of 100,000 and rounded down a number
(a third way started like this
n*(n+1)*(n+2)(n+3)=100000
The value is 1.1. Because it is 1.1 spaces away. the negative symbol isn’t,t important in this case.
Answer:
a) 6 2/5
b) 13 1/2
Step-by-step explanation:
Have a nice day!
Can I maybe have brainliest?
I forgot it was simplify..
You have two unknown rates, so we need to develop two equations to solve for these unknowns (based on the information given on the problem statement):
5x + 10y = 725
x + y = 100
By substitution, we get:
5x + 10(100 - x) = 725
5x + 1000 - 10x = 725
-5x = 725 - 1000
-5x = -275
x = -275/-5 = 55
100 - 55 = 45
Thus:
The mechanic who worked for 5 hours charged his time at $55/hr, and the mechanic who worked for 10 hours charged his time at $45/hr.
To verify, plug and chug the results back into the original equations:
5(55) + 10(45) = 725
275 + 450 = 725
725 = 725 [OK]
55 + 45 = 100 [OK]
Answer:
The answer is "The threat to internal validity is mortality".
Step-by-step explanation:
It signifies that while in terms of your study, persons were "morning." It usually signifies when people leave the studies. There will be only likely if indeed the experiment lasts a long period that it'll be a substantial danger to validity and reliability because the chance for drops increases. Eight content validity risks are history, maturity, instrument, test, choice, average regress, human engagement, and mortality.
