A submarine is running at a depth of 235 ft underwater. It changes course and rises 101 ft. What is the change in elevation?

Bumek [7]

Answer:

The change in elevation is -134 ft

Step-by-step explanation:

Given;

initial depth of the submarine, d₁ = 235 ft

final depth of the submarine, d₂ = 101 ft

The change in the elevation of the submarine is given by;

Δd = d₂ - d₁

Δd = 101 ft - 235 ft

Δd = -134 ft

The change in elevation is negative because the submarine is moving closer to the surface.

Therefore, the change in elevation is -134 ft

Suppose that weights of bags of potato chips coming from a factory follow a normal distribution with mean 12.8 ounces and standa

MA_775_DIABLO [31]

Answer:

std dev = 0.625

Step-by-step explanation:

Given that weights of bags of potato chips coming from a factory follow a normal distribution with mean 12.8 ounces and standard deviation .6 ounces.

We must change std deviation such that

P(X<12) =0.01

Mean would remain the same as 12.8 oz

From normal distribution score we can find

10th percentile is -1.28\

i.e. we must have

$12.8-1.28*s = 12\\1.28s = 0.8\\s = 0.625$

Std deviation should be 0.625
