Answer: (2.5 ; 1.5 )
Step-by-step explanation:
- The midpoint of the segment with the points
and 
is calculated by the formula:
The <u>correct answer</u> is C) yes, the answer is written in scientific notation.
Explanation:
In scientific notation, we have a decimal number multiplied by a power of 10. The decimal number has the decimal point behind the first non-zero digit, and the exponent on the power of 10 tells us how many places to move the decimal.
In this problem, we have 5.6, which has the decimal after the first non-zero digit. We also have 10¹², which tells us to move the decimal 12 places.
This is in scientific notation.
Remember, the exact value cannot involve any rounding or estimates. Now, let's solve this problem. First, we have to translate it into an expression:
√72 - √8 + √128 separate the terms into square roots
√36·2 - √4·2 + √64·2 square root the terms that you can
6√2 - 2√2 + 8√2 they have like radical terms, so combine the terms
6 - 2 + 8 = 12 the coefficients are 12 when combined
12√2 this is the EXACT VALUE of the expression
Hope this helps!
Answer: 29.1
Step-by-step explanation: You would multiply 15$ by .94 which is the same as 94% and get 14.1. You would then add the 14.1 to the 15$ and get 29.1$.
Randomly assigned group. the art class isn't random and only consists of a select type of people--it is not a representative sample; maybe more left handed people enjoy art than do right handed people! therefore, even though the randomly assigned group is smaller, it is the better estimate.
