A rectangular parking lot has an area of 1650 yd.² the length of the parking lot is 55 yards what is the width of the parking lo

nikitadnepr [17]

Answer:

The width of parking lot is 30 yards.

Step-by-step explanation:

Given that:

Area of rectangular parking lot = 1650 yards square

Length of parking lot = 55 yards

Width of parking lot = x yards

Area of rectangle is given by:

A = Length * Width

1650 = 55x

Dividing both sides by 55

$\frac{55x}{55}=\frac{1650}{55}\\x=30$

Hence,

The width of parking lot is 30 yards.

Tabitha's mom is trying to decide between two plumber companies to fix her sink.

ohaa [14]

Answer:

the amount due for 3 hours would be $52 + ($34/hr)(3 hrs) = $154

Step-by-step explanation:

Write two equations, one for the total cost payable to Water R Us and another to Clogs:

$52 + ($34/hr)t = $34 + ($40/hr)t, or

$18 = ($6/hr)t, which tells us that t = 3 (That's 3 hours).

At the time the charges from the two companies would be the same (3 hours into the job), the amount due for 3 hours would be

$52 + ($34/hr)(3 hrs) = $154

An airplane begins a descent to a sea-level airport at an angle of -4° to the horizon. What is the change in elevation after it

mote1985 [20]

Using the slope concept, it is found that the change in elevation was of -699 feet.

<h3>What is a slope?</h3>

The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.

In this problem, we have that:

The vertical change is of h.

The horizontal change is of 10,000 feet.

The angle is of -4º.

Hence:

tan(-4º) = h/10000

h = 10000 x tan(-4º)

h = -699.

Answer:

Step-by-step explanation:

<u>Excel's Normal Distribution</u>

The normal distribution has two parameters: the mean value $\mu$ and the standard deviation $\sigma$ . Since it's a symmetric function the values at the right side of the center value

The normal distribution is a function which integral cannot be expressed in terms of elemental functions. That is why the cumulative probability is usually found in tables, graphs or any digital media like Excel.

The formula NORM.DIST computes the cumulative values for the left tail or $P( X < X_o)$ for a given mean and standard deviation. The parameters are

$NORM.DIST (X_o,\mu,\sigma,cumulative)$

This last parameter tells the formula we want the cumulative left-tail probability or just the value at Xo. This value must be set to TRUE to compute the probability for a range of values, like in the problem at hand.

Since the formula computes the left-tail of the function, we must take advantage of the symmetry of the distribution if we want to compute right-tail values we just subtract the result from 1.

Thus, the correct formula to calculate the required probability is

D. 1 – NORM.DIST(100, 75, 10, TRUE)
