Answer and working out attached below. Hope it helps
Simplifying
0.5p + -3.45 = -1.2
Reorder the terms:
-3.45 + 0.5p = -1.2
Solving
-3.45 + 0.5p = -1.2
Solving for variable 'p'.
Move all terms containing p to the left, all other terms to the right.
Add '3.45' to each side of the equation.
-3.45 + 3.45 + 0.5p = -1.2 + 3.45
Combine like terms: -3.45 + 3.45 = 0.00
0.00 + 0.5p = -1.2 + 3.45
0.5p = -1.2 + 3.45
Combine like terms: -1.2 + 3.45 = 2.25
0.5p = 2.25
Divide each side by '0.5'.
p = 4.5
Simplifying
p = 4.5
2x⁴(2x² + 3x + 4)
Simplify.
4x⁶ + 6x⁵ + 8x⁴ ==> The second answer choice.
We know this because :
Multiply 2x⁴ with 2x²
2x⁴ × 2x² = 4x⁶
Then, do :
2x⁴ × 3x = 6x⁵
Then, finally, do :
2x⁴ × 4 = 8x⁴
So, our answer looks like this :
4x⁶ + 6x⁵ + 8x⁴

Answer:
b. 2
Step-by-step explanation:
The standard error of the sample mean is the standard deviation of the sample divided by the square root of the size of the sample.
In this problem, we have that:
Sample standard deviation of 14, sample size of 49.
So
So the correct answer is:
b. 2
