Th owner must buy 7 Jackets
Step-by-step explanation:
a. Purchase price=$55 , Sell Price= $77
Sell Price = $55+$22
= Purchase price + 40*55/100
=Purchase price + 40% of Purchase price
=140% of purchase price
b. Purchase Price=$35
Sell price=140%of $35
=140*$35/100
=$49
Number of Jackets required for the total sale to be $340 = $340/$49
=6.94
So We get the result by rounding off because Jackets cannot be in fraction, which is 7
Answer:
<h3>B.)Segment BC is proportional to segment EF, and angles A and D are congruent.</h3>
Step-by-step explanation:
If ΔABC and ΔDEF are similar, then
AB is proportional to DE
BC is proportional to EF
CA is proportional to FD
and
angles A and D are congruent
angles B and E are congruent
angles C and F are congruent
18/5= 3.6
square root of 11= 3.316
1 to the 3rd power is 1
pie=3.14
4= 4
square root to the third power= 3
Which sampling method divides the population up into sections, randomly selects some of those sections, then chooses all the members from the selected sections to study?
What is Cluster Sampling?
Cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research. Researchers then select random groups with a simple random or systematic random sampling technique for data collection and data analysis.
So, The above mentioned type of sampling is called cluster sampling.
Cluster sampling is a sampling technique in which the entire population of interest is divide into clusters or groups, then the investigator randomly selects some of these clusters and all the members of these randomly selected clusters are investigated.

Answer: A = ≈28.55 cm²
Step-by-step explanation:
It is drawn as if it should be a triangle minus a rectangle with an area of
½(10)(13) - (7)(6) = 23 cm²
However it is not to scale.
The angle on the right side is
θ = arctan10/13 = 37.56859...°
Meaning the right triangle has a height of
h = 4tan37.56859 = 3.07692 cm
So the right triangle has an area of
Ar = ½(3.07692)(4) = 6.15384... cm²
The left hand side consists of a triangle over a rectangle
The height of the triangle is 4, the base is is 4/tan37.56859 = 5.2 cm
so the left area is
(2)(6) + ½(5.2)(4) = 22.4 cm²
So the sum of the areas of the two enclosed shapes is
A = 22.4 + 6.15384... = 28.55384... ≈28.55 cm²
