Answer is d
Step-by-step explanation:
If you multiply a^6 and a it equals a^7
Answer:
6 x (-4)
= (-24)
Step-by-step explanation:
when multiplying integers, you first need to multiply the numbers. Then you need to look at the signs if both numbers have the same signs or if it doesn't. if the signs are the same, the product is a positive . If the two numbers have different signs, you will get a negative product.
NOTE: if a number doesn't have a sign, it's a positive number
Each pencil cost $2.
Explanation: She had $24 before buying the pencils and after she had $10. 24-10=14 so the total she spent on pencils was $14. She bought 7 pencils so you divide 14 by 7 (14/7=2) which equals 2. So each pencil cost $2.
Given parameters:
Total length of curtains bought = 20m
She used 8m for the living room
She used 7m for the dining room
unknown:
Quantity used for the kitchen = ?
Solution:
Quantity used for the kitchen = Total length - (living room + dining room)
Input the parameters given solve;
Quantity used for the kitchen = 20 - (8 + 7) = 5m
The length of curtain used for the kitchen is 5m
Answer:
Recall that probability is given as; the number of required outcome over the number of total possible outcome.
The probability that a transmitter receives the signal being sent by itself is given as 
.
when there are n transmitters, the probability will be given as 
Step-by-step explanation:
Probability simply the likelihood of an event occurring or not occurring.
Probability therefore is given as; the number of required outcome over number of possible outcome.
In the case of the first part above we have the number of required outcome to be at least one divided by the number of possible outcome which is 3.
while in the second part we have the number o possible outcome to be n.
