Answer:
A. 6^2/7 and (√6)^7
Step-by-step explanation:
Because we can't get 6 out of root as a whole we need to use the power to show its value when we do so.
The power of (√6)^7 has is seven and degree of the root is 2 so we have to put 2/7 over 6 when we take it out of root.
Answer:
N=11/5

Answer:
Hypothesis testing of ' significance of difference between means'
Step-by-step explanation:
Study conducted to tests whether oxygen level prior SAT score improves test score. This can be done through - Hypothesis testing of ' significance of difference between means'.
Where x1 & x2 represent mean values of SAT test score before (or without) & after (or with) oxygen.
Null hypothesis [H0] = x1 = x2 , Alternate Hypothesis [H1] : x1 < x2

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
2x + y = 3
-2x + 5y = -9
<u>Step 2: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
- Combine equations: 6y = -6
- Divide 6 on both sides: y = -1
<u>Step 3: Solve for </u><em><u>x</u></em>
- Define equation: 2x + y = 3
- Substitute in <em>y</em>: 2x - 1 = 3
- Isolate <em>y</em> term: 2x = 4
- Isolate <em>y</em>: x = 2
