General Formulas and Concepts:
<u>Algebra I</u>
- Standard Form: ax² + bx + c = 0
- Factoring
- Finding roots
Step-by-step explanation:
<u>Step 1: Define equation</u>
5u² + 6 = -13u
<u>Step 2: Solve for </u><em><u>u</u></em>
- Rewrite: 5u² + 13u + 6 = 0
- Factor: (u + 2)(5u + 3) = 0
- Find roots: u = -2, -3/5
Answer:
The answer would be HFG = KIJ (A)
If we know that the opposite and the adjacent side of the triangle are congruent, then the hypotenuse is congruent too. Therefor, A is correct as we know the opposite side and the adjacent side are congruent.
Answer:
22
Step-by-step explanation:
(5x-7 )+(4x-11)=180 ( it equals 180 because those two angles equal 180)
Then add the similar things together
5x+4x=9x
-7-11= -18
9x-18=180, add 18 on both sides to get 9x alone
9x=180, then divide 180 by 9 to get x alone
x=22

Answer:
D. The new box plot will be positively skewed.
Step-by-step explanation:
We have been given a box plot which represents the the heights (in feet) of a sample of pine trees.
We are asked to determine that affect of adding a pine tree that is 140 feet tall to the sample.
We can see from our box plot that the tallest pine tree is 75 feet and 140 is approximately 2 times greater than 75.
After adding the a tree that is 140 feet tall, the maximum height will be 140 and our right whisker will be at point 140.
Since we know that for a positive skewed data, the tail of the distribution is longer on the right hand side.
As 140 is a extreme positive outlier for our given data set, therefore, after adding a tree that is 140 feet tall our box plot will be positively skewed and option D is the correct choice.
