Answer:
first problem: 1,2,4
second problem: D
Step-by-step explanation:
A. 6
B. –6
C. –30
D. 30
Answer:
D. 38x + 1,450 > 4,000
Step-by-step explanation:
It has to be greater than 4,000 so A makes no sense
The parentheses are in the wrong place completely changing the meaning for B
C disregards the info we have about how she's already typed 1,450 words
The answer has to be D
Step-by-step explanation:
2.36 light-years
4.33 light-years
5.36 light-years
Answer:
The distance, in light-years, from Earth to the star is 4.33 light- years.
Step-by-step explanation:
As given
Distances in space are measured in light-years.
As
Thus
by using the exponent property .
Therefore the distance, in light-years, from Earth to the star is 4.33 light- years.
B) Yes. P(married and exercise in the morning) = P(married)·P(exercise in the morning) = 45%
C) No. P(married and exercise in the morning) = 60% & P(married)·P(exercise in the morning) = 42%
D) No. P(married and exercise in the morning) = 45% & P(married)·P(exercise in the morning) = 34.2%
Answer:
D) No. P(married and exercise in the morning) = 45% & P(married)·P(exercise in the morning) = 34.2%
Step-by-step explanation:
Divisibility rule of 2: All even numbers are divisible by 2 means no remainder will be left. For example- 4,6,10,18,26 etc
Divisibility rule of 3: A number is divisible by 3 if the sum of the digits is divisible by 3. For example- 15,54,213,699 etc
Divisibility rule of 5: A number is divisible by 5 if the number's last digit is either 0 or 5. For example- 40,85,255,3600,6510 etc
Divisibility rule of 10: The last digit must be zero. For example-100,450,2500,3010,5860 etc
Divisibility rule of 7: To know if a given number is divisible by 7, we will take the last digit of the number and double it. Then we will subtract the result from the rest of the number. If the resulting number is evenly divisible by 7, then the original number is also divisible by 7. For example: 2555, 5509,203, 287 etc
Lets check for 2555. double the last digit. 5 is doubled to 10. Then subtract 10 from 255 this gives 245. 245 is divisible by 7, so 2555 is divisible by 7.
this is the reason, divisibility rule of 7 is complicated as compared to other given number.
