Answer:
x=12
Step-by-step explanation:
The values of x and y is x = 2 1/4, y = 6.
We can write the corresponding dimensions:
Larger: smaller
Heigh: 8 : y
Width: 12 : 9
Depth: 3 : x
Since the figures are similar, corresponding values are proportional. This means
y/8 = 9/12
y = 8(9/12)
y = 6
x/3 = 9/12
x = 3(9/12) = 9/4
x = 2 1/4

Answer:
0.6808
Step-by-step explanation:
First, find the standard deviation of the sample.
s = σ / √n
s = 3 / √49
s = 0.429
Next, find the z-score.
z = (x − μ) / s
z = (28.8 − 29) / 0.429
z = -0.467
Use a calculator or z-score table to find the probability.
Using a table:
P(x > -0.47) = 1 − 0.3192 = 0.6808
Using a calculator:
P(x > -0.467) = 0.6796
