The dress is on sale for 35% off the regular price (w). What expression represents the sale price of the wedding dress?

Aleonysh [2.5K]

Expression that represents the sale price of the wedding dress is $s = 0.65w$

Solution:

Given that, the dress is on sale for 35 % off the regular price

Let the regular price of dress be "w"

To find: Expression that represents the sale price of the wedding dress

Let "s" be the sale price of wedding dress

Sale price = Regular price - discount price

Discount price is given as:

Discount price = 35 % of regular price

Discount price = 35 % of w

$\rightarrow 35 \% \times w\\\\\rightarrow \frac{35}{100} \times w\\\\\rightarrow 0.35w$

Thus discount price = 0.35w

Expression for the sale price of the wedding dress:

Sale price = Regular price - discount price

s = w - 0.35w

s = 0.65w

Thus expression that represents the sale price of the wedding dress is $s = 0.65w$

A person at ground level measures the angle of elevation to the top of a building to be 74degrees if at this point the person is

SOVA2 [1]

See the attached figure

Let
h---------> building tall

we know that
tan 74°=h/34---------> h=34*tan 74°--------> 34*3.487------> 118.57
h=118.6 ft

the answer is h=118.6 ft

Answer:

The median = Median = $77,153.5

Step-by-step explanation:

Given the data :

199999 98789 90878 87678 87245 83675 77876 77743 76564 76465 75643 66768 65654 58768 54678 51354

Measures of central tendency are used to describe the center or midpoint of a group of observation. They could include the mean, median and mode.

Mean described the average value of the distribution

Median, the middle observation.

Mode, the observation which occurs most

Using online calculator to save time ;

the mean = 83,111.06

Median = 77153.5

For the mode, all the values have a frequency of 1

Plotting the data on an histogram, it could be observed that the Data is positively skewed and hence, not symmetrical.

Since the distribution is not symmetrical, using the mean isn't the best and the mode is also not usable.

Therefore, the median seems to be the best of the 3 measures
