Step-by-step explanation:
6 times 4,
Answer:
x = 12
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
3x - 7 = 29
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 7 on both sides: 3x = 36
- Divide 3 on both sides: x = 12
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: 3(12) - 7 = 29
- Multiply: 36 - 7 = 29
- Subtract: 29 = 29
Here we see that 29 does indeed equal 29.
∴ x = 12 is a solution of the equation.
Answer: H0 : u = 6 ounces
Ha : u not equal to 6 ounces
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean.
While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above;
H0 : u = 6
Ha : u not equal to 6.
