Answer:
0.0035289
Step-by-step explanation:
From the question;
mean annual salary = $63,500
n = sample size = 31
Standard deviation = $6,200
Firstly, we calculate the z-score of $60,500
Mathematically;
z-score = x-mean/SD/√n = (60500-63500)/6200/√(31) = -2.6941
So we want to find the probability that P(z < -2.6941)
We can get this from the standard normal table
P( z < -2.6941) = 0.0035289
Answer:
A rectangle is a 2-dimensional polygon with four sides,
Step-by-step explanation:
four angles, and four vertices. A rectangle is composed of two sides: length (L) and width (W). The length of a rectangle is the longest side, whereas the width is the shortest side. The width of a rectangle is sometimes referred to as the breadth (b).
Answer:
sin-1 (24/25).
Step-by-step explanation:
We are given the opposite side to the given angle (24 ft) and the hypotenuse (25 ft) .
sin = opposite / hypotenuse
- so it is sin-1 (24/25).
