A is correct because it’s the only answer that starts with five
The horizontal and vertical vector components of the velocity vector V, namely Vx and Vy are; 505.32 ft/s and 721.57 ft/s respectively
<h3>Horizontal and Vertical components of vectors</h3>
For ease of computation since vectors have magnitude and direction; they are resolved into horizontal and vertical components.
By convention, the horizontal, Vx and vertical components, Vy are as follows;
- Vx = V cos π
- Vy = V sin π
where π = angle of inclination to the horizontal.
Hence,
- Vx = 881 × cos55° = 505.32 ft/s
- Vy = 881 × sin55° = 721.57 ft/s

By direct correspondence AB = PQ
Answer:
.
Step-by-step explanation:
The z-score for a normal distribution is calculated using the formula:
.
From the question, the distribution has a mean of 50.
and the standard deviation is 
.
For a z-score to be negative, then, 
.
.
.
.
.
.
Any value less than 50 will produce a negative z-score
