Answer:
it's equivalent to B. 6x + 5
Explanation:
Given
f(x) = -2x + 5
f(- 3x) = - 2 * (-3x) + 5 = 6x + 5
the answer is gas hope you pass
The option that describes the relationship between the two confidence intervals is; The width of I₈₁ will be¹/₉ the width of I₉
<h3>How to calculate width of the confidence interval with normal distribution?</h3>
The width of the confidence interval will be calculated from the formula;
W = 2Z(σ/√n)
where;
z is the z-score at given confidence level
σ is standard deviation
n is sample size
For first sample;
W_i9 = 2Z(σ/√9)
W_i9 = ²/₃Zσ
For second Sample;
W_i81 = 2Z(σ/√81)
W_i81 = ²/₉Zσ
Thus, we will have;
W_i9/W_i81 = (²/₃Zσ)/(²/₉Zσ)
W_i9/W_i81 = 9
W_i81 = ¹/₉W_i9

The box would accelerate in the same direction (to the right) as the truck as shown by this free-body diagram.
<h3>What is a free-body diagram?</h3>
A free-body diagram is a graphical illustration which is typically used in the field of science to visualize moments, tension, and applied forces that are acting on an isolated or rigid object (body), while using arrows to point in the direction of these forces.
In this scenario, the box would accelerate in the same direction (to the right) as the truck in accordance with Newton's Second Law of Motion.
As shown in the free-body diagram, the forces that are acting on both the heavy box and truck include the following:
