Height of the water after 3 minutes is 31.25 inches

<h3><u>Solution:</u></h3>

Given that height of the water in a fish pond is 42.5 inches

Water is being drained from the pond at a rate of 3.75 inches per minute

<em><u>To find:  height of the water after 3 minutes</u></em>

According to given information,

Water drained in 1 minute = 3.75 inches

<em><u>So height of the water after 3 minutes is calculated by following steps:</u></em>

1) find how much water is drained in 3 minutes

2) subtract value obtained in step 1 from total height of water in fish pond

<h3><u>Step 1:</u></h3>

water is drained in 3 minutes = Water drained in 1 minute x 3

\text {water is drained in } 3 \text { minutes }=3.75 \times 3=11.25

Thus water drained in 3 minutes is 11.25 inches

<h3><u>Step 2:</u></h3>

height of the water after 3 minutes = total height of water in fish pond - water drained in 3 minutes

height of the water after 3 minutes = 42.5 - 11.25 = 31.25 inches

Thus height of the water after 3 minutes is 31.25 inches

Weights of cars passing over a bridge part 2<br>​
DaniilM [7]

Step-by-step explanation:

The solution to this problem is very much similar to your previous ones, already answered by Sqdancefan.

Given:

mean,  mu = 3550 lbs (hope I read the first five correctly, and it's not a six)

standard deviation, sigma = 870 lbs

weights are normally distributed, and assume large samples.

Probability to be estimated between W1=2800 and W2=4500 lbs.

Solution:

We calculate Z-scores for each of the limits in order to estimate probabilities from tables.

For W1 (lower limit),

Z1=(W1-mu)/sigma = (2800 - 3550)/870 = -.862069

From tables, P(Z<Z1) = 0.194325

For W2 (upper limit):

Z2=(W2-mu)/sigma = (4500-3550)/879 = 1.091954

From tables, P(Z<Z2) = 0.862573

Therefore probability that weight is between W1 and W2 is

P( W1 < W < W2 )

= P(Z1 < Z < Z2)

= P(Z<Z2) - P(Z<Z1)

= 0.862573 - 0.194325

= 0.668248

= 0.67 (to the hundredth)

Which complex number does NOT fall within the shaded region in this graph?
avanturin [10]
In order to find which is the answer, we will go step-by-step. Numbers that are not followed by I are drawn on the Real Axis and the other ones are drawn on the Imaginary Axis. You go first on the Real Axis and then on the Imaginary Axis and intersect those 2 points. If a number does not have an imaginary or real part you can assume that is equal to 0. As you can notice the number that is not in the shaded area is <span>2 − I</span>
