Answer:
$870.83 or $870
Step-by-step explanation:
Combine fractions:
1 / 4 + 2 / 3
multiply both sides by their denominators.
1 × 3 / 4 × 3 + 2 × 4 / 3 × 4
3 / 12 + 8 / 12
= 11 / 12
950 × 11 / 12
950 × 11 = 10,450
10,450 ÷ 12 = $870.8
Answer: 0.7071
Step-by-step explanation:
The first thing to do is to calculate the R² which is the coefficient of determination. This will be:
= 1 - SSE/SS Total
= 1 - 600/1200
= 1 - 0.5
= 0.5
Then, the correlation coefficient will be:
= ✓0.5
= 0.7071
<h3>
Answer: Choice A</h3>
Explanation:
Notice how the input 5 leads to the output 3 when we look at the S(x) function. The inverse will undo this. So that must mean the answer is choice A where we have the input 3 lead to the output 5. In short, the inputs and outputs swap places. This means the domain and ranges swap.

Answer:
6
Step-by-step explanation:
This can be solved by the use of proportions
2/5÷3=x÷7.2
Cross multiply to solve
2/5*7.2=18
3*x=3x
We now have 3x=18
Divide by 3 and get 6
Hope this helps!
