11z > -33
11z / 11 > 33 / 11
z > 3
Hope it helps!
For quite some time now, calculators have had statistical functions built in. Here we need to use the stat. function normalcdf, which has only two inputs when we're working with z scores instead of raw scores.
Here,
normalcdf(-100,1.25) = 0.894
This same result could be obtained using a table of z-scores.
Answer: The radius is 8.76 inches.
Step-by-step explanation:
18.25/12.5 = 1.46
1.46 * 6 = 8.76

Answer:
True
Step-by-step explanation:
The smallest the product could be is 4×4 = 16.
The largest the product could be is 5×5 = 25.
The product must be between 16 and 25. (true)
Answer:
The distance of Satelite from the earth's surface = 2720.12 miles
Step-by-step explanation:
Below is the calculation for distance:
Use Pythagorean theorem
Distance, d² = 5400² + 4000²
d² = 45160000
d = 6720.12
Subtract the radius to find the distance from earth's surface.
Distance = 6720.12 - 4000 = 2720.12
The distance of Satelite from the earth's surface = 2720.12 miles
