Answer: D
Step-by-step explanation:
a^2 +b^2 = c^2
= 18
3\sqrt{2}^2= 18
18 + 18 = 36
The square root of 36 is 6
Answer:
If the game with 3 hits is ignored the data becomes:
- 7, 7, 8, 8, 8, 8, 9, 9, 9, 9, 9, 10, 10, 10, 10, 11, 11, 11, 11
a) The mean will increase.
<u>With 3:</u>
- (3 + 7*2 + 8*4 + 9*5 + 10*4 + 11*4)/20 = 8.9
<u>Without 3:</u>
- (7*2 + 8*4 + 9*5 + 10*4 + 11*4)/19 = 9.21
b) The median will remain as is.
- With 3 and without the median is same = 9
Answer:
A. H<0
Step-by-step explanation:
<em>Add by 4 from both sides of equation.</em>
<em>-4+4>-4+h+4</em>
<em>Simplify.</em>
<em>0>h</em>
<em>Then, switch sides to find the answer.</em>
<em>h<0</em>
<em>h<0 is the correct answer.</em>
Given: ∠A is a straight angle. ∠B is a straight angle.
We need to Prove: ∠A≅∠B.
We know straight angles are of measure 180°.
So, ∠A and <B both would be of 180°.
It is given that ∠A and ∠B are straight angles. This means that <u>both angles are of 180°</u> because of the <u>the definition of straight angles</u>. Using <u>the definition of equality</u>, m∠A=m∠B . Finally, ∠A≅∠B by <u>definition of congruent. </u>
