Answer:
To find the value of missing exponent, we have to split the number which is in other side of equal sign (which is not having power) as the multiple of base of the missing exponent.
On both sides, powers have the same base, so their exponents must be equal.
Step-by-step explanation:
<h3>Problem 1:</h3>
Write the missing exponent:
25=5^x
Let x be the missing exponent.
To find the value missing exponent, we have to split the number which is in the left side as the multiple of the base of the missing exponent.
That is,
25=5*5 or 5^2
Now,
5^2=5^x
Powers have the same base so their exponent must be equal.
Hence the missing exponent is 2

Answer:
36%
Step-by-step explanation:
the <em>complement </em>of it raining on at least one of these days = it not raining on any day
this means that if it does not rain on at least one day, it does not rain on any day
thus,
1 - probability of it not raining at all = probability it rains at least one day
probability it doesn't rain on monday = 1- 20% = 80%
probability it doesn't rain on tuesday = 1 - 20% = 80%
probability it doesn't rain on monday AND it doesn't rain on tuesday = probability it doesn't rain at all
P(A and B) = P(A) * P(B) = 0.8 * 0.8 = 0.64
1 - 0.64 = 0.36 as our answer
Answer:
Multiply row 2 by-1 and add it to row 3.
Step-by-step explanation:
The given augmented matrix is ![\left[\begin{array}{ccc}3&-21&15\\15&8&15\\-2&-1&3\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D3%26-21%2615%5C%5C15%268%2615%5C%5C-2%26-1%263%5Cend%7Barray%7D%5Cright%5D)
The permissible row operations are:
1. Switching rows
2. Multiplying a row by a nonzero constant.
3. Adding/Subtracting two rows
Therefore the correct option is: Multiply row 2 by-1 and add it to row 3.
<u>Answer</u>:
Elisa.
She withdraws $20 at a time and has a star of $140.
140 ÷ 20 = 7.
Francis withdraws 45 dollars at a time and has a start of $270.
270 ÷ 45 = 6
Elsa has the greater number of withdrawals.
