Answer:
<h2>- 417</h2>
Step-by-step explanation:
n - integer
The sum of n and 181 is equal to -236:
n + 181 = -236 <em>subtract 181 from both sides</em>
n + 181 - 181 = -236 - 181
n = -417
0.0038 is the probability that the code is 9Z.
<u>Step-by-step explanation:</u>
Here we have , A code consists of a digit chosen from 0 to 9 followed by a letter of the alphabet. We need to find What is the probability that the code is 9Z . Let's find out:
A code consists of a digit between 0-9 , i.e. there are 10 choices . And followed by a letter i.e. from A-Z having 26 choices ! So combinations possible are :
0{A-Z}=26
1{A-Z} = 26
2{A-Z} = 26
3{ A-Z}=26
.......
9{A-Z}=26 or ,
⇒ 10(26)
⇒
Now , 9Z is one combination ! So , probability :
⇒
⇒
Therefore , 0.0038 is the probability that the code is 9Z.
Hey there! I'm happy to help!
We want to put this 0.002 into scientific notation, where you put it as a one digit number multiplied by 10 raised to a certain power.
If we move the decimal to the right 3 times, we will have 2. We will multiply this 2 by to show that it is still equal to 0.002.
So, the mass of the mustard seed is 2×.
Now, we multiply this mustard seed mass by the number of mustard seeds to find the weight of all of the mustard seeds combined.
(2×)×(4.3602×)
Let's round 4.3602 to the nearest whole number, which is 4. We multiply those two together.
2×4=8
And we multiply the two exponents. When multiplying them, you add the numbers in the exponent. -3 and 4 combined gives us 1, and 10 the first power is just 10.
So, a good estimate for the mass of the mustard seeds is 80 grams, which is the same as (2×)×(4×)=8×
Have a wonderful day! :D
