Her average in first three test = 89
This means, her total scores in first three test were = 3 x 89 = 267
Her average in four tests = 91
This means, her total scores in four tests are = 364
267 give the sum of first three test scores. and 364 give the sum of scores with fourth test adding in three tests.
So, subtracting 267 from 364 will give us the scores of Fourth test.
Scores of Fourth test = 364 - 267 = 97
Thus, Samantha's Claim is correct
I believe it is 1/3, but probability is not my strong suit.
Answer:
Qualitative data
Step-by-step explanation:
Qualitative methods like an interviews and observations that are considered valuable as of their detail, descriptiveness, and uniqueness.
In this given situation, it is already known that the specific painter who outperforms in the factory.
And my motive is to gain an understanding with respect to the performing as a best painter for an automative industry so the same information would be observed and interviewed him
Answer:
No
Step-by-step explanation:
2√3 × 2√6
= 4√18
= 4√9*2
= 4( 2√2)
= 8√2
Just multiply the numbers under the radical together. √3 × √6 = √18. √18 can be written as √9*2, or 3√3.
√2 is irrational, so the answer will be irrational
Volume is a three-dimensional scalar quantity. The volume of the triangular prism is 66cm².
<h3>What is volume?</h3>
A volume is a scalar number that expresses the amount of three-dimensional space enclosed by a closed surface.
Given the length of the triangle is 4cm, while the width of the triangle is 11cm, therefore, the area of the base of the triangle will be,
Area of triangle = 0.5 × 4cm × 11cm
Area of triangle = 22 cm²
Now, the volume of the prism with a base area of 22cm² and a height of 3 cm is,
Volume of the triangular prism = 22cm² × 3cm = 66cm³
Hence, the volume of the triangular prism is 66cm².
